The Free Translation Project is +a way to get maintainers of free software, translators, and users all +together, so that free software will gradually become able to speak many +languages. A few packages already provide translations for their +messages. + + If you found this `ABOUT-NLS' file inside a distribution, you may +assume that the distributed package does use GNU `gettext' internally, +itself available at your nearest GNU archive site. But you do _not_ +need to install GNU `gettext' prior to configuring, installing or using +this package with messages translated. + + Installers will find here some useful hints. These notes also +explain how users should proceed for getting the programs to use the +available translations. They tell how people wanting to contribute and +work on translations can contact the appropriate team. + +1.1 INSTALL Matters +=================== + +Some packages are "localizable" when properly installed; the programs +they contain can be made to speak your own native language. Most such +packages use GNU `gettext'. Other packages have their own ways to +internationalization, predating GNU `gettext'. + + By default, this package will be installed to allow translation of +messages. It will automatically detect whether the system already +provides the GNU `gettext' functions. Installers may use special +options at configuration time for changing the default behaviour. The +command: + + ./configure --disable-nls + +will _totally_ disable translation of messages. + + When you already have GNU `gettext' installed on your system and run +configure without an option for your new package, `configure' will +probably detect the previously built and installed `libintl' library +and will decide to use it. If not, you may have to to use the +`--with-libintl-prefix' option to tell `configure' where to look for it. + + Internationalized packages usually have many `po/LL.po' files, where +LL gives an ISO 639 two-letter code identifying the language. Unless +translations have been forbidden at `configure' time by using the +`--disable-nls' switch, all available translations are installed +together with the package. However, the environment variable `LINGUAS' +may be set, prior to configuration, to limit the installed set. +`LINGUAS' should then contain a space separated list of two-letter +codes, stating which languages are allowed. + +1.2 Using This Package +====================== + +As a user, if your language has been installed for this package, you +only have to set the `LANG' environment variable to the appropriate +`LL_CC' combination. If you happen to have the `LC_ALL' or some other +`LC_xxx' environment variables set, you should unset them before +setting `LANG', otherwise the setting of `LANG' will not have the +desired effect. Here `LL' is an ISO 639 two-letter language code, and +`CC' is an ISO 3166 two-letter country code. For example, let's +suppose that you speak German and live in Germany. At the shell +prompt, merely execute `setenv LANG de_DE' (in `csh'), +`export LANG; LANG=de_DE' (in `sh') or `export LANG=de_DE' (in `bash'). +This can be done from your `.login' or `.profile' file, once and for +all. + + You might think that the country code specification is redundant. +But in fact, some languages have dialects in different countries. For +example, `de_AT' is used for Austria, and `pt_BR' for Brazil. The +country code serves to distinguish the dialects. + + The locale naming convention of `LL_CC', with `LL' denoting the +language and `CC' denoting the country, is the one use on systems based +on GNU libc. On other systems, some variations of this scheme are +used, such as `LL' or `LL_CC.ENCODING'. You can get the list of +locales supported by your system for your language by running the +command `locale -a | grep '^LL''. + + Not all programs have translations for all languages. By default, an +English message is shown in place of a nonexistent translation. If you +understand other languages, you can set up a priority list of languages. +This is done through a different environment variable, called +`LANGUAGE'. GNU `gettext' gives preference to `LANGUAGE' over `LANG' +for the purpose of message handling, but you still need to have `LANG' +set to the primary language; this is required by other parts of the +system libraries. For example, some Swedish users who would rather +read translations in German than English for when Swedish is not +available, set `LANGUAGE' to `sv:de' while leaving `LANG' to `sv_SE'. + + Special advice for Norwegian users: The language code for Norwegian +bokma*l changed from `no' to `nb' recently (in 2003). During the +transition period, while some message catalogs for this language are +installed under `nb' and some older ones under `no', it's recommended +for Norwegian users to set `LANGUAGE' to `nb:no' so that both newer and +older translations are used. + + In the `LANGUAGE' environment variable, but not in the `LANG' +environment variable, `LL_CC' combinations can be abbreviated as `LL' +to denote the language's main dialect. For example, `de' is equivalent +to `de_DE' (German as spoken in Germany), and `pt' to `pt_PT' +(Portuguese as spoken in Portugal) in this context. + +1.3 Translating Teams +===================== + +For the Free Translation Project to be a success, we need interested +people who like their own language and write it well, and who are also +able to synergize with other translators speaking the same language. +Each translation team has its own mailing list. The up-to-date list of +teams can be found at the Free Translation Project's homepage, +`http://translationproject.org/', in the "Teams" area. + + If you'd like to volunteer to _work_ at translating messages, you +should become a member of the translating team for your own language. +The subscribing address is _not_ the same as the list itself, it has +`-request' appended. For example, speakers of Swedish can send a +message to `sv-request@li.org', having this message body: + + subscribe + + Keep in mind that team members are expected to participate +_actively_ in translations, or at solving translational difficulties, +rather than merely lurking around. If your team does not exist yet and +you want to start one, or if you are unsure about what to do or how to +get started, please write to `coordinator@translationproject.org' to +reach the coordinator for all translator teams. + + The English team is special. It works at improving and uniformizing +the terminology in use. Proven linguistic skills are praised more than +programming skills, here. + +1.4 Available Packages +====================== + +Languages are not equally supported in all packages. The following +matrix shows the current state of internationalization, as of June +2010. The matrix shows, in regard of each package, for which languages +PO files have been submitted to translation coordination, with a +translation percentage of at least 50%. + + Ready PO files af am an

Of course you have to respect the GNU Library General Public +License which covers the use of the GNU `gettext' library. This means +in particular that even non-free programs can use `libintl' as a shared +library, whereas only free software can use `libintl' as a static +library or use modified versions of `libintl'. + + Once the sources are changed appropriately and the setup can handle +the use of `gettext' the only thing missing are the translations. The +Free Translation Project is also available for packages which are not +developed inside the GNU project. Therefore the information given above +applies also for every other Free Software Project. Contact +`coordinator@translationproject.org' to make the `.pot' files available +to the translation teams. + diff --git a/AUTHORS b/AUTHORS new file mode 100644 index 0000000..05c7838 --- /dev/null +++ b/AUTHORS @@ -0,0 +1,77 @@ +This file lists people who have made significant contributions to the +nano editor.

By contrast, +the GNU General Public License is intended to guarantee your freedom to +share and change all versions of a program--to make sure it remains free +software for all its users. We, the Free Software Foundation, use the +GNU General Public License for most of our software; it applies also to +any other work released this way by its authors. You can apply it to +your programs, too. + + When we speak of free software, we are referring to freedom, not +price. Our General Public Licenses are designed to make sure that you +have the freedom to distribute copies of free software (and charge for +them if you wish), that you receive source code or can get it if you +want it, that you can change the software or use pieces of it in new +free programs, and that you know you can do these things. + + To protect your rights, we need to prevent others from denying you +these rights or asking you to surrender the rights. Therefore, you have +certain responsibilities if you distribute copies of the software, or if +you modify it: responsibilities to respect the freedom of others. + + For example, if you distribute copies of such a program, whether +gratis or for a fee, you must pass on to the recipients the same +freedoms that you received. You must make sure that they, too, receive +or can get the source code. And you must show them these terms so they +know their rights. + + Developers that use the GNU GPL protect your rights with two steps: +(1) assert copyright on the software, and (2) offer you this License +giving you legal permission to copy, distribute and/or modify it. + + For the developers' and authors' protection, the GPL clearly explains +that there is no warranty for this free software. For both users' and +authors' sake, the GPL requires that modified versions be marked as +changed, so that their problems will not be attributed erroneously to +authors of previous versions. + + Some devices are designed to deny users access to install or run +modified versions of the software inside them, although the manufacturer +can do so. This is fundamentally incompatible with the aim of +protecting users' freedom to change the software. The systematic +pattern of such abuse occurs in the area of products for individuals to +use, which is precisely where it is most unacceptable. Therefore, we +have designed this version of the GPL to prohibit the practice for those +products. If such problems arise substantially in other domains, we +stand ready to extend this provision to those domains in future versions +of the GPL, as needed to protect the freedom of users. + + Finally, every program is threatened constantly by software patents. +States should not allow patents to restrict development and use of +software on general-purpose computers, but in those that do, we wish to +avoid the special danger that patents applied to a free program could +make it effectively proprietary. To prevent this, the GPL assures that +patents cannot be used to render the program non-free. + + The precise terms and conditions for copying, distribution and +modification follow. + + TERMS AND CONDITIONS + + 0. Definitions. + + "This License" refers to version 3 of the GNU General Public License. + + "Copyright" also means copyright-like laws that apply to other kinds of +works, such as semiconductor masks. + + "The Program" refers to any copyrightable work licensed under this +License. Each licensee is addressed as "you". "Licensees" and +"recipients" may be individuals or organizations. + + To "modify" a work means to copy from or adapt all or part of the work +in a fashion requiring copyright permission, other than the making of an +exact copy. The resulting work is called a "modified version" of the +earlier work or a work "based on" the earlier work. + + A "covered work" means either the unmodified Program or a work based +on the Program. + + To "propagate" a work means to do anything with it that, without +permission, would make you directly or secondarily liable for +infringement under applicable copyright law, except executing it on a +computer or modifying a private copy. Propagation includes copying, +distribution (with or without modification), making available to the +public, and in some countries other activities as well. + + To "convey" a work means any kind of propagation that enables other +parties to make or receive copies. Mere interaction with a user through +a computer network, with no transfer of a copy, is not conveying. + + An interactive user interface displays "Appropriate Legal Notices" +to the extent that it includes a convenient and prominently visible +feature that (1) displays an appropriate copyright notice, and (2) +tells the user that there is no warranty for the work (except to the +extent that warranties are provided), that licensees may convey the +work under this License, and how to view a copy of this License. If +the interface presents a list of user commands or options, such as a +menu, a prominent item in the list meets this criterion. + + 1. Source Code. + + The "source code" for a work means the preferred form of the work +for making modifications to it. "Object code" means any non-source +form of a work. + + A "Standard Interface" means an interface that either is an official +standard defined by a recognized standards body, or, in the case of +interfaces specified for a particular programming language, one that +is widely used among developers working in that language. + + The "System Libraries" of an executable work include anything, other +than the work as a whole, that (a) is included in the normal form of +packaging a Major Component, but which is not part of that Major +Component, and (b) serves only to enable use of the work with that +Major Component, or to implement a Standard Interface for which an +implementation is available to the public in source code form. A +"Major Component", in this context, means a major essential component +(kernel, window system, and so on) of the specific operating system +(if any) on which the executable work runs, or a compiler used to +produce the work, or an object code interpreter used to run it. + + The "Corresponding Source" for a work in object code form means all +the source code needed to generate, install, and (for an executable +work) run the object code and to modify the work, including scripts to +control those activities. However, it does not include the work's +System Libraries, or general-purpose tools or generally available free +programs which are used unmodified in performing those activities but +which are not part of the work. For example, Corresponding Source +includes interface definition files associated with source files for +the work, and the source code for shared libraries and dynamically +linked subprograms that the work is specifically designed to require, +such as by intimate data communication or control flow between those +subprograms and other parts of the work. + + The Corresponding Source need not include anything that users +can regenerate automatically from other parts of the Corresponding +Source. + + The Corresponding Source for a work in source code form is that +same work. + + 2. Basic Permissions. + + All rights granted under this License are granted for the term of +copyright on the Program, and are irrevocable provided the stated +conditions are met. This License explicitly affirms your unlimited +permission to run the unmodified Program. The output from running a +covered work is covered by this License only if the output, given its +content, constitutes a covered work. This License acknowledges your +rights of fair use or other equivalent, as provided by copyright law. + + You may make, run and propagate covered works that you do not +convey, without conditions so long as your license otherwise remains +in force. You may convey covered works to others for the sole purpose +of having them make modifications exclusively for you, or provide you +with facilities for running those works, provided that you comply with +the terms of this License in conveying all material for which you do +not control copyright. Those thus making or running the covered works +for you must do so exclusively on your behalf, under your direction +and control, on terms that prohibit them from making any copies of +your copyrighted material outside their relationship with you. + + Conveying under any other circumstances is permitted solely under +the conditions stated below. Sublicensing is not allowed; section 10 +makes it unnecessary. + + 3. Protecting Users' Legal Rights From Anti-Circumvention Law. + + No covered work shall be deemed part of an effective technological +measure under any applicable law fulfilling obligations under article +11 of the WIPO copyright treaty adopted on 20 December 1996, or +similar laws prohibiting or restricting circumvention of such +measures. + + When you convey a covered work, you waive any legal power to forbid +circumvention of technological measures to the extent such circumvention +is effected by exercising rights under this License with respect to +the covered work, and you disclaim any intention to limit operation or +modification of the work as a means of enforcing, against the work's +users, your or third parties' legal rights to forbid circumvention of +technological measures. + + 4. Conveying Verbatim Copies. + + You may convey verbatim copies of the Program's source code as you +receive it, in any medium, provided that you conspicuously and +appropriately publish on each copy an appropriate copyright notice; +keep intact all notices stating that this License and any +non-permissive terms added in accord with section 7 apply to the code; +keep intact all notices of the absence of any warranty; and give all +recipients a copy of this License along with the Program. + + You may charge any price or no price for each copy that you convey, +and you may offer support or warranty protection for a fee. + + 5. Conveying Modified Source Versions. + + You may convey a work based on the Program, or the modifications to +produce it from the Program, in the form of source code under the +terms of section 4, provided that you also meet all of these conditions: + + a) The work must carry prominent notices stating that you modified + it, and giving a relevant date. + + b) The work must carry prominent notices stating that it is + released under this License and any conditions added under section + 7. This requirement modifies the requirement in section 4 to + "keep intact all notices". + + c) You must license the entire work, as a whole, under this + License to anyone who comes into possession of a copy. This + License will therefore apply, along with any applicable section 7 + additional terms, to the whole of the work, and all its parts, + regardless of how they are packaged. This License gives no + permission to license the work in any other way, but it does not + invalidate such permission if you have separately received it. + + d) If the work has interactive user interfaces, each must display + Appropriate Legal Notices; however, if the Program has interactive + interfaces that do not display Appropriate Legal Notices, your + work need not make them do so. + + A compilation of a covered work with other separate and independent +works, which are not by their nature extensions of the covered work, +and which are not combined with it such as to form a larger program, +in or on a volume of a storage or distribution medium, is called an +"aggregate" if the compilation and its resulting copyright are not +used to limit the access or legal rights of the compilation's users +beyond what the individual works permit. Inclusion of a covered work +in an aggregate does not cause this License to apply to the other +parts of the aggregate. + + 6. Conveying Non-Source Forms. + + You may convey a covered work in object code form under the terms +of sections 4 and 5, provided that you also convey the +machine-readable Corresponding Source under the terms of this License, +in one of these ways: + + a) Convey the object code in, or embodied in, a physical product + (including a physical distribution medium), accompanied by the + Corresponding Source fixed on a durable physical medium + customarily used for software interchange. + + b) Convey the object code in, or embodied in, a physical product + (including a physical distribution medium), accompanied by a + written offer, valid for at least three years and valid for as + long as you offer spare parts or customer support for that product + model, to give anyone who possesses the object code either (1) a + copy of the Corresponding Source for all the software in the + product that is covered by this License, on a durable physical + medium customarily used for software interchange, for a price no + more than your reasonable cost of physically performing this + conveying of source, or (2) access to copy the + Corresponding Source from a network server at no charge. + + c) Convey individual copies of the object code with a copy of the + written offer to provide the Corresponding Source. This + alternative is allowed only occasionally and noncommercially, and + only if you received the object code with such an offer, in accord + with subsection 6b. + + d) Convey the object code by offering access from a designated + place (gratis or for a charge), and offer equivalent access to the + Corresponding Source in the same way through the same place at no + further charge. You need not require recipients to copy the + Corresponding Source along with the object code. If the place to + copy the object code is a network server, the Corresponding Source + may be on a different server (operated by you or a third party) + that supports equivalent copying facilities, provided you maintain + clear directions next to the object code saying where to find the + Corresponding Source. Regardless of what server hosts the + Corresponding Source, you remain obligated to ensure that it is + available for as long as needed to satisfy these requirements. + + e) Convey the object code using peer-to-peer transmission, provided + you inform other peers where the object code and Corresponding + Source of the work are being offered to the general public at no + charge under subsection 6d. + + A separable portion of the object code, whose source code is excluded +from the Corresponding Source as a System Library, need not be +included in conveying the object code work. + + A "User Product" is either (1) a "consumer product", which means any +tangible personal property which is normally used for personal, family, +or household purposes, or (2) anything designed or sold for incorporation +into a dwelling. In determining whether a product is a consumer product, +doubtful cases shall be resolved in favor of coverage. For a particular +product received by a particular user, "normally used" refers to a +typical or common use of that class of product, regardless of the status +of the particular user or of the way in which the particular user +actually uses, or expects or is expected to use, the product. A product +is a consumer product regardless of whether the product has substantial +commercial, industrial or non-consumer uses, unless such uses represent +the only significant mode of use of the product. + + "Installation Information" for a User Product means any methods, +procedures, authorization keys, or other information required to install +and execute modified versions of a covered work in that User Product from +a modified version of its Corresponding Source. The information must +suffice to ensure that the continued functioning of the modified object +code is in no case prevented or interfered with solely because +modification has been made. + + If you convey an object code work under this section in, or with, or +specifically for use in, a User Product, and the conveying occurs as +part of a transaction in which the right of possession and use of the +User Product is transferred to the recipient in perpetuity or for a +fixed term (regardless of how the transaction is characterized), the +Corresponding Source conveyed under this section must be accompanied +by the Installation Information. But this requirement does not apply +if neither you nor any third party retains the ability to install +modified object code on the User Product (for example, the work has +been installed in ROM). + + The requirement to provide Installation Information does not include a +requirement to continue to provide support service, warranty, or updates +for a work that has been modified or installed by the recipient, or for +the User Product in which it has been modified or installed. Access to a +network may be denied when the modification itself materially and +adversely affects the operation of the network or violates the rules and +protocols for communication across the network. + + Corresponding Source conveyed, and Installation Information provided, +in accord with this section must be in a format that is publicly +documented (and with an implementation available to the public in +source code form), and must require no special password or key for +unpacking, reading or copying. + + 7. Additional Terms. + + "Additional permissions" are terms that supplement the terms of this +License by making exceptions from one or more of its conditions. +Additional permissions that are applicable to the entire Program shall +be treated as though they were included in this License, to the extent +that they are valid under applicable law. If additional permissions +apply only to part of the Program, that part may be used separately +under those permissions, but the entire Program remains governed by +this License without regard to the additional permissions. + + When you convey a copy of a covered work, you may at your option +remove any additional permissions from that copy, or from any part of +it. (Additional permissions may be written to require their own +removal in certain cases when you modify the work.) You may place +additional permissions on material, added by you to a covered work, +for which you have or can give appropriate copyright permission. + + Notwithstanding any other provision of this License, for material you +add to a covered work, you may (if authorized by the copyright holders of +that material) supplement the terms of this License with terms: + + a) Disclaiming warranty or limiting liability differently from the + terms of sections 15 and 16 of this License; or + + b) Requiring preservation of specified reasonable legal notices or + author attributions in that material or in the Appropriate Legal + Notices displayed by works containing it; or + + c) Prohibiting misrepresentation of the origin of that material, or + requiring that modified versions of such material be marked in + reasonable ways as different from the original version; or + + d) Limiting the use for publicity purposes of names of licensors or + authors of the material; or + + e) Declining to grant rights under trademark law for use of some + trade names, trademarks, or service marks; or + + f) Requiring indemnification of licensors and authors of that + material by anyone who conveys the material (or modified versions of + it) with contractual assumptions of liability to the recipient, for + any liability that these contractual assumptions directly impose on + those licensors and authors. + + All other non-permissive additional terms are considered "further +restrictions" within the meaning of section 10. If the Program as you +received it, or any part of it, contains a notice stating that it is +governed by this License along with a term that is a further +restriction, you may remove that term. If a license document contains +a further restriction but permits relicensing or conveying under this +License, you may add to a covered work material governed by the terms +of that license document, provided that the further restriction does +not survive such relicensing or conveying. + + If you add terms to a covered work in accord with this section, you +must place, in the relevant source files, a statement of the +additional terms that apply to those files, or a notice indicating +where to find the applicable terms. + + Additional terms, permissive or non-permissive, may be stated in the +form of a separately written license, or stated as exceptions; +the above requirements apply either way. + + 8. Termination. + + You may not propagate or modify a covered work except as expressly +provided under this License. Any attempt otherwise to propagate or +modify it is void, and will automatically terminate your rights under +this License (including any patent licenses granted under the third +paragraph of section 11). + + However, if you cease all violation of this License, then your +license from a particular copyright holder is reinstated (a) +provisionally, unless and until the copyright holder explicitly and +finally terminates your license, and (b) permanently, if the copyright +holder fails to notify you of the violation by some reasonable means +prior to 60 days after the cessation. + + Moreover, your license from a particular copyright holder is +reinstated permanently if the copyright holder notifies you of the +violation by some reasonable means, this is the first time you have +received notice of violation of this License (for any work) from that +copyright holder, and you cure the violation prior to 30 days after +your receipt of the notice. + + Termination of your rights under this section does not terminate the +licenses of parties who have received copies or rights from you under +this License. If your rights have been terminated and not permanently +reinstated, you do not qualify to receive new licenses for the same +material under section 10. + + 9. Acceptance Not Required for Having Copies. + + You are not required to accept this License in order to receive or +run a copy of the Program. Ancillary propagation of a covered work +occurring solely as a consequence of using peer-to-peer transmission +to receive a copy likewise does not require acceptance. However, +nothing other than this License grants you permission to propagate or +modify any covered work. These actions infringe copyright if you do +not accept this License. Therefore, by modifying or propagating a +covered work, you indicate your acceptance of this License to do so. + + 10. Automatic Licensing of Downstream Recipients. + + Each time you convey a covered work, the recipient automatically +receives a license from the original licensors, to run, modify and +propagate that work, subject to this License. You are not responsible +for enforcing compliance by third parties with this License. + + An "entity transaction" is a transaction transferring control of an +organization, or substantially all assets of one, or subdividing an +organization, or merging organizations. If propagation of a covered +work results from an entity transaction, each party to that +transaction who receives a copy of the work also receives whatever +licenses to the work the party's predecessor in interest had or could +give under the previous paragraph, plus a right to possession of the +Corresponding Source of the work from the predecessor in interest, if +the predecessor has it or can get it with reasonable efforts. + + You may not impose any further restrictions on the exercise of the +rights granted or affirmed under this License. For example, you may +not impose a license fee, royalty, or other charge for exercise of +rights granted under this License, and you may not initiate litigation +(including a cross-claim or counterclaim in a lawsuit) alleging that +any patent claim is infringed by making, using, selling, offering for +sale, or importing the Program or any portion of it. + + 11. Patents. + + A "contributor" is a copyright holder who authorizes use under this +License of the Program or a work on which the Program is based. The +work thus licensed is called the contributor's "contributor version". + + A contributor's "essential patent claims" are all patent claims +owned or controlled by the contributor, whether already acquired or +hereafter acquired, that would be infringed by some manner, permitted +by this License, of making, using, or selling its contributor version, +but do not include claims that would be infringed only as a +consequence of further modification of the contributor version. For +purposes of this definition, "control" includes the right to grant +patent sublicenses in a manner consistent with the requirements of +this License. + + Each contributor grants you a non-exclusive, worldwide, royalty-free +patent license under the contributor's essential patent claims, to +make, use, sell, offer for sale, import and otherwise run, modify and +propagate the contents of its contributor version. + + In the following three paragraphs, a "patent license" is any express +agreement or commitment, however denominated, not to enforce a patent +(such as an express permission to practice a patent or covenant not to +sue for patent infringement). To "grant" such a patent license to a +party means to make such an agreement or commitment not to enforce a +patent against the party. + + If you convey a covered work, knowingly relying on a patent license, +and the Corresponding Source of the work is not available for anyone +to copy, free of charge and under the terms of this License, through a +publicly available network server or other readily accessible means, +then you must either (1) cause the Corresponding Source to be so +available, or (2) arrange to deprive yourself of the benefit of the +patent license for this particular work, or (3) arrange, in a manner +consistent with the requirements of this License, to extend the patent +license to downstream recipients. "Knowingly relying" means you have +actual knowledge that, but for the patent license, your conveying the +covered work in a country, or your recipient's use of the covered work +in a country, would infringe one or more identifiable patents in that +country that you have reason to believe are valid. + + If, pursuant to or in connection with a single transaction or +arrangement, you convey, or propagate by procuring conveyance of, a +covered work, and grant a patent license to some of the parties +receiving the covered work authorizing them to use, propagate, modify +or convey a specific copy of the covered work, then the patent license +you grant is automatically extended to all recipients of the covered +work and works based on it. + + A patent license is "discriminatory" if it does not include within +the scope of its coverage, prohibits the exercise of, or is +conditioned on the non-exercise of one or more of the rights that are +specifically granted under this License. You may not convey a covered +work if you are a party to an arrangement with a third party that is +in the business of distributing software, under which you make payment +to the third party based on the extent of your activity of conveying +the work, and under which the third party grants, to any of the +parties who would receive the covered work from you, a discriminatory +patent license (a) in connection with copies of the covered work +conveyed by you (or copies made from those copies), or (b) primarily +for and in connection with specific products or compilations that +contain the covered work, unless you entered into that arrangement, +or that patent license was granted, prior to 28 March 2007. + + Nothing in this License shall be construed as excluding or limiting +any implied license or other defenses to infringement that may +otherwise be available to you under applicable patent law. + + 12. No Surrender of Others' Freedom. + + If conditions are imposed on you (whether by court order, agreement or +otherwise) that contradict the conditions of this License, they do not +excuse you from the conditions of this License. If you cannot convey a +covered work so as to satisfy simultaneously your obligations under this +License and any other pertinent obligations, then as a consequence you may +not convey it at all. For example, if you agree to terms that obligate you +to collect a royalty for further conveying from those to whom you convey +the Program, the only way you could satisfy both those terms and this +License would be to refrain entirely from conveying the Program. + + 13. Use with the GNU Affero General Public License. + + Notwithstanding any other provision of this License, you have +permission to link or combine any covered work with a work licensed +under version 3 of the GNU Affero General Public License into a single +combined work, and to convey the resulting work. The terms of this +License will continue to apply to the part which is the covered work, +but the special requirements of the GNU Affero General Public License, +section 13, concerning interaction through a network will apply to the +combination as such. + + 14. Revised Versions of this License. + + The Free Software Foundation may publish revised and/or new versions of +the GNU General Public License from time to time. Such new versions will +be similar in spirit to the present version, but may differ in detail to +address new problems or concerns. + + Each version is given a distinguishing version number. If the +Program specifies that a certain numbered version of the GNU General +Public License "or any later version" applies to it, you have the +option of following the terms and conditions either of that numbered +version or of any later version published by the Free Software +Foundation. If the Program does not specify a version number of the +GNU General Public License, you may choose any version ever published +by the Free Software Foundation. + + If the Program specifies that a proxy can decide which future +versions of the GNU General Public License can be used, that proxy's +public statement of acceptance of a version permanently authorizes you +to choose that version for the Program. + + Later license versions may give you additional or different +permissions. However, no additional obligations are imposed on any +author or copyright holder as a result of your choosing to follow a +later version. + + 15. Disclaimer of Warranty. + + THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY +APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT +HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY +OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, +THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR +PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM +IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF +ALL NECESSARY SERVICING, REPAIR OR CORRECTION. + + 16. Limitation of Liability. + + IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING +WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS +THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY +GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE +USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF +DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD +PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), +EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF +SUCH DAMAGES. + + 17. Interpretation of Sections 15 and 16. + + If the disclaimer of warranty and limitation of liability provided +above cannot be given local legal effect according to their terms, +reviewing courts shall apply local law that most closely approximates +an absolute waiver of all civil liability in connection with the +Program, unless a warranty or assumption of liability accompanies a +copy of the Program in return for a fee. + + END OF TERMS AND CONDITIONS + + How to Apply These Terms to Your New Programs + + If you develop a new program, and you want it to be of the greatest +possible use to the public, the best way to achieve this is to make it +free software which everyone can redistribute and change under these terms. + + To do so, attach the following notices to the program. It is safest +to attach them to the start of each source file to most effectively +state the exclusion of warranty; and each file should have at least +the "copyright" line and a pointer to where the full notice is found. + + + Copyright (C) + + This program is free software: you can redistribute it and/or modify + it under the terms of the GNU General Public License as published by + the Free Software Foundation, either version 3 of the License, or + (at your option) any later version. + + This program is distributed in the hope that it will be useful, + but WITHOUT ANY WARRANTY; without even the implied warranty of + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the + GNU General Public License for more details. + + You should have received a copy of the GNU General Public License + along with this program. If not, see . + +Also add information on how to contact you by electronic and paper mail. + + If the program does terminal interaction, make it output a short +notice like this when it starts in an interactive mode: + + Copyright (C) + This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'. + This is free software, and you are welcome to redistribute it + under certain conditions; type `show c' for details. + +The hypothetical commands `show w' and `show c' should show the appropriate +parts of the General Public License. Of course, your program's commands +might be different; for a GUI interface, you would use an "about box". + + You should also get your employer (if you work as a programmer) or school, +if any, to sign a "copyright disclaimer" for the program, if necessary. +For more information on this, and how to apply and follow the GNU GPL, see +. + + The GNU General Public License does not permit incorporating your program +into proprietary programs. If your program is a subroutine library, you +may consider it more useful to permit linking proprietary applications with +the library. If this is what you want to do, use the GNU Lesser General +Public License instead of this License.

PREAMBLE + +The purpose of this License is to make a manual, textbook, or other +functional and useful document "free" in the sense of freedom: to +assure everyone the effective freedom to copy and redistribute it, +with or without modifying it, either commercially or noncommercially. +Secondarily, this License preserves for the author and publisher a way +to get credit for their work, while not being considered responsible +for modifications made by others. + +This License is a kind of "copyleft", which means that derivative +works of the document must themselves be free in the same sense. It +complements the GNU General Public License, which is a copyleft +license designed for free software. + +We have designed this License in order to use it for manuals for free +software, because free software needs free documentation: a free +program should come with manuals providing the same freedoms that the +software does. But this License is not limited to software manuals; +it can be used for any textual work, regardless of subject matter or +whether it is published as a printed book. We recommend this License +principally for works whose purpose is instruction or reference. + + +1. APPLICABILITY AND DEFINITIONS + +This License applies to any manual or other work, in any medium, that +contains a notice placed by the copyright holder saying it can be +distributed under the terms of this License. Such a notice grants a +world-wide, royalty-free license, unlimited in duration, to use that +work under the conditions stated herein. The "Document", below, +refers to any such manual or work. Any member of the public is a +licensee, and is addressed as "you". You accept the license if you +copy, modify or distribute the work in a way requiring permission +under copyright law. + +A "Modified Version" of the Document means any work containing the +Document or a portion of it, either copied verbatim, or with +modifications and/or translated into another language. + +A "Secondary Section" is a named appendix or a front-matter section of +the Document that deals exclusively with the relationship of the +publishers or authors of the Document to the Document's overall subject +(or to related matters) and contains nothing that could fall directly +within that overall subject. (Thus, if the Document is in part a +textbook of mathematics, a Secondary Section may not explain any +mathematics.) The relationship could be a matter of historical +connection with the subject or with related matters, or of legal, +commercial, philosophical, ethical or political position regarding +them. + +The "Invariant Sections" are certain Secondary Sections whose titles +are designated, as being those of Invariant Sections, in the notice +that says that the Document is released under this License. If a +section does not fit the above definition of Secondary then it is not +allowed to be designated as Invariant. The Document may contain zero +Invariant Sections. If the Document does not identify any Invariant +Sections then there are none. + +The "Cover Texts" are certain short passages of text that are listed, +as Front-Cover Texts or Back-Cover Texts, in the notice that says that +the Document is released under this License. A Front-Cover Text may +be at most 5 words, and a Back-Cover Text may be at most 25 words. + +A "Transparent" copy of the Document means a machine-readable copy, +represented in a format whose specification is available to the +general public, that is suitable for revising the document +straightforwardly with generic text editors or (for images composed of +pixels) generic paint programs or (for drawings) some widely available +drawing editor, and that is suitable for input to text formatters or +for automatic translation to a variety of formats suitable for input +to text formatters. A copy made in an otherwise Transparent file +format whose markup, or absence of markup, has been arranged to thwart +or discourage subsequent modification by readers is not Transparent. +An image format is not Transparent if used for any substantial amount +of text. A copy that is not "Transparent" is called "Opaque". + +Examples of suitable formats for Transparent copies include plain +ASCII without markup, Texinfo input format, LaTeX input format, SGML +or XML using a publicly available DTD, and standard-conforming simple +HTML, PostScript or PDF designed for human modification. Examples of +transparent image formats include PNG, XCF and JPG. Opaque formats +include proprietary formats that can be read and edited only by +proprietary word processors, SGML or XML for which the DTD and/or +processing tools are not generally available, and the +machine-generated HTML, PostScript or PDF produced by some word +processors for output purposes only. + +The "Title Page" means, for a printed book, the title page itself, +plus such following pages as are needed to hold, legibly, the material +this License requires to appear in the title page. For works in +formats which do not have any title page as such, "Title Page" means +the text near the most prominent appearance of the work's title, +preceding the beginning of the body of the text. + +A section "Entitled XYZ" means a named subunit of the Document whose +title either is precisely XYZ or contains XYZ in parentheses following +text that translates XYZ in another language. (Here XYZ stands for a +specific section name mentioned below, such as "Acknowledgements", +"Dedications", "Endorsements", or "History".) To "Preserve the Title" +of such a section when you modify the Document means that it remains a +section "Entitled XYZ" according to this definition. + +The Document may include Warranty Disclaimers next to the notice which +states that this License applies to the Document. These Warranty +Disclaimers are considered to be included by reference in this +License, but only as regards disclaiming warranties: any other +implication that these Warranty Disclaimers may have is void and has +no effect on the meaning of this License. + + +2. VERBATIM COPYING + +You may copy and distribute the Document in any medium, either +commercially or noncommercially, provided that this License, the +copyright notices, and the license notice saying this License applies +to the Document are reproduced in all copies, and that you add no other +conditions whatsoever to those of this License. You may not use +technical measures to obstruct or control the reading or further +copying of the copies you make or distribute. However, you may accept +compensation in exchange for copies. If you distribute a large enough +number of copies you must also follow the conditions in section 3. + +You may also lend copies, under the same conditions stated above, and +you may publicly display copies. + + +3. COPYING IN QUANTITY + +If you publish printed copies (or copies in media that commonly have +printed covers) of the Document, numbering more than 100, and the +Document's license notice requires Cover Texts, you must enclose the +copies in covers that carry, clearly and legibly, all these Cover +Texts: Front-Cover Texts on the front cover, and Back-Cover Texts on +the back cover. Both covers must also clearly and legibly identify +you as the publisher of these copies. The front cover must present +the full title with all words of the title equally prominent and +visible. You may add other material on the covers in addition. +Copying with changes limited to the covers, as long as they preserve +the title of the Document and satisfy these conditions, can be treated +as verbatim copying in other respects. + +If the required texts for either cover are too voluminous to fit +legibly, you should put the first ones listed (as many as fit +reasonably) on the actual cover, and continue the rest onto adjacent +pages. + +If you publish or distribute Opaque copies of the Document numbering +more than 100, you must either include a machine-readable Transparent +copy along with each Opaque copy, or state in or with each Opaque copy +a computer-network location from which the general network-using +public has access to download using public-standard network protocols +a complete Transparent copy of the Document, free of added material. +If you use the latter option, you must take reasonably prudent steps, +when you begin distribution of Opaque copies in quantity, to ensure +that this Transparent copy will remain thus accessible at the stated +location until at least one year after the last time you distribute an +Opaque copy (directly or through your agents or retailers) of that +edition to the public. + +It is requested, but not required, that you contact the authors of the +Document well before redistributing any large number of copies, to give +them a chance to provide you with an updated version of the Document. + + +4. MODIFICATIONS + +You may copy and distribute a Modified Version of the Document under +the conditions of sections 2 and 3 above, provided that you release +the Modified Version under precisely this License, with the Modified +Version filling the role of the Document, thus licensing distribution +and modification of the Modified Version to whoever possesses a copy +of it. In addition, you must do these things in the Modified Version: + +A. Use in the Title Page (and on the covers, if any) a title distinct + from that of the Document, and from those of previous versions + (which should, if there were any, be listed in the History section + of the Document). You may use the same title as a previous version + if the original publisher of that version gives permission. +B. List on the Title Page, as authors, one or more persons or entities + responsible for authorship of the modifications in the Modified + Version, together with at least five of the principal authors of the + Document (all of its principal authors, if it has fewer than five), + unless they release you from this requirement. +C. State on the Title page the name of the publisher of the + Modified Version, as the publisher. +D. Preserve all the copyright notices of the Document. +E. Add an appropriate copyright notice for your modifications + adjacent to the other copyright notices. +F. Include, immediately after the copyright notices, a license notice + giving the public permission to use the Modified Version under the + terms of this License, in the form shown in the Addendum below. +G. Preserve in that license notice the full lists of Invariant Sections + and required Cover Texts given in the Document's license notice. +H. Include an unaltered copy of this License. +I. Preserve the section Entitled "History", Preserve its Title, and add + to it an item stating at least the title, year, new authors, and + publisher of the Modified Version as given on the Title Page. If + there is no section Entitled "History" in the Document, create one + stating the title, year, authors, and publisher of the Document as + given on its Title Page, then add an item describing the Modified + Version as stated in the previous sentence. +J. Preserve the network location, if any, given in the Document for + public access to a Transparent copy of the Document, and likewise + the network locations given in the Document for previous versions + it was based on. These may be placed in the "History" section. + You may omit a network location for a work that was published at + least four years before the Document itself, or if the original + publisher of the version it refers to gives permission. +K. For any section Entitled "Acknowledgements" or "Dedications", + Preserve the Title of the section, and preserve in the section all + the substance and tone of each of the contributor acknowledgements + and/or dedications given therein. +L. Preserve all the Invariant Sections of the Document, + unaltered in their text and in their titles. Section numbers + or the equivalent are not considered part of the section titles. +M. Delete any section Entitled "Endorsements". Such a section + may not be included in the Modified Version. +N. Do not retitle any existing section to be Entitled "Endorsements" + or to conflict in title with any Invariant Section. +O. Preserve any Warranty Disclaimers. + +If the Modified Version includes new front-matter sections or +appendices that qualify as Secondary Sections and contain no material +copied from the Document, you may at your option designate some or all +of these sections as invariant. To do this, add their titles to the +list of Invariant Sections in the Modified Version's license notice. +These titles must be distinct from any other section titles. + +You may add a section Entitled "Endorsements", provided it contains +nothing but endorsements of your Modified Version by various +parties--for example, statements of peer review or that the text has +been approved by an organization as the authoritative definition of a +standard. + +You may add a passage of up to five words as a Front-Cover Text, and a +passage of up to 25 words as a Back-Cover Text, to the end of the list +of Cover Texts in the Modified Version. Only one passage of +Front-Cover Text and one of Back-Cover Text may be added by (or +through arrangements made by) any one entity. If the Document already +includes a cover text for the same cover, previously added by you or +by arrangement made by the same entity you are acting on behalf of, +you may not add another; but you may replace the old one, on explicit +permission from the previous publisher that added the old one. + +The author(s) and publisher(s) of the Document do not by this License +give permission to use their names for publicity for or to assert or +imply endorsement of any Modified Version. + + +5. COMBINING DOCUMENTS + +You may combine the Document with other documents released under this +License, under the terms defined in section 4 above for modified +versions, provided that you include in the combination all of the +Invariant Sections of all of the original documents, unmodified, and +list them all as Invariant Sections of your combined work in its +license notice, and that you preserve all their Warranty Disclaimers. + +The combined work need only contain one copy of this License, and +multiple identical Invariant Sections may be replaced with a single +copy. If there are multiple Invariant Sections with the same name but +different contents, make the title of each such section unique by +adding at the end of it, in parentheses, the name of the original +author or publisher of that section if known, or else a unique number. +Make the same adjustment to the section titles in the list of +Invariant Sections in the license notice of the combined work. + +In the combination, you must combine any sections Entitled "History" +in the various original documents, forming one section Entitled +"History"; likewise combine any sections Entitled "Acknowledgements", +and any sections Entitled "Dedications". You must delete all sections +Entitled "Endorsements". + + +6. COLLECTIONS OF DOCUMENTS + +You may make a collection consisting of the Document and other documents +released under this License, and replace the individual copies of this +License in the various documents with a single copy that is included in +the collection, provided that you follow the rules of this License for +verbatim copying of each of the documents in all other respects. + +You may extract a single document from such a collection, and distribute +it individually under this License, provided you insert a copy of this +License into the extracted document, and follow this License in all +other respects regarding verbatim copying of that document. + + +7. AGGREGATION WITH INDEPENDENT WORKS + +A compilation of the Document or its derivatives with other separate +and independent documents or works, in or on a volume of a storage or +distribution medium, is called an "aggregate" if the copyright +resulting from the compilation is not used to limit the legal rights +of the compilation's users beyond what the individual works permit. +When the Document is included in an aggregate, this License does not +apply to the other works in the aggregate which are not themselves +derivative works of the Document. + +If the Cover Text requirement of section 3 is applicable to these +copies of the Document, then if the Document is less than one half of +the entire aggregate, the Document's Cover Texts may be placed on +covers that bracket the Document within the aggregate, or the +electronic equivalent of covers if the Document is in electronic form. +Otherwise they must appear on printed covers that bracket the whole +aggregate. + + +8. TRANSLATION + +Translation is considered a kind of modification, so you may +distribute translations of the Document under the terms of section 4. +Replacing Invariant Sections with translations requires special +permission from their copyright holders, but you may include +translations of some or all Invariant Sections in addition to the +original versions of these Invariant Sections. You may include a +translation of this License, and all the license notices in the +Document, and any Warranty Disclaimers, provided that you also include +the original English version of this License and the original versions +of those notices and disclaimers. In case of a disagreement between +the translation and the original version of this License or a notice +or disclaimer, the original version will prevail. + +If a section in the Document is Entitled "Acknowledgements", +"Dedications", or "History", the requirement (section 4) to Preserve +its Title (section 1) will typically require changing the actual +title. + + +9. TERMINATION + +You may not copy, modify, sublicense, or distribute the Document except +as expressly provided for under this License. Any other attempt to +copy, modify, sublicense or distribute the Document is void, and will +automatically terminate your rights under this License. However, +parties who have received copies, or rights, from you under this +License will not have their licenses terminated so long as such +parties remain in full compliance. + + +10. FUTURE REVISIONS OF THIS LICENSE + +The Free Software Foundation may publish new, revised versions +of the GNU Free Documentation License from time to time. Such new +versions will be similar in spirit to the present version, but may +differ in detail to address new problems or concerns. See +http://www.gnu.org/copyleft/. + +Each version of the License is given a distinguishing version number. +If the Document specifies that a particular numbered version of this +License "or any later version" applies to it, you have the option of +following the terms and conditions either of that specified version or +of any later version that has been published (not as a draft) by the +Free Software Foundation. If the Document does not specify a version +number of this License, you may choose any version ever published (not +as a draft) by the Free Software Foundation. + + +ADDENDUM: How to use this License for your documents + +To use this License in a document you have written, include a copy of +the License in the document and put the following copyright and +license notices just after the title page: + + Copyright (c) YEAR YOUR NAME. + Permission is granted to copy, distribute and/or modify this document + under the terms of the GNU Free Documentation License, Version 1.2 + or any later version published by the Free Software Foundation; + with no Invariant Sections, no Front-Cover Texts, and no Back-Cover Texts. + A copy of the license is included in the section entitled "GNU + Free Documentation License". + +If you have Invariant Sections, Front-Cover Texts and Back-Cover Texts, +replace the "with...Texts." line with this: + + with the Invariant Sections being LIST THEIR TITLES, with the + Front-Cover Texts being LIST, and with the Back-Cover Texts being LIST. + +If you have Invariant Sections without Cover Texts, or some other +combination of the three, merge those two alternatives to suit the +situation. + +If your document contains nontrivial examples of program code, we +recommend releasing these examples in parallel under your choice of +free software license, such as the GNU General Public License, +to permit their use in free software. diff --git a/ChangeLog b/ChangeLog new file mode 100644 index 0000000..e8c5f71 --- /dev/null +++ b/ChangeLog @@ -0,0

This file is offered as-is, +without warranty of any kind. + +Basic Installation +================== + + Briefly, the shell command './configure && make && make install' +should configure, build, and install this package. The following +more-detailed instructions are generic; see the 'README' file for +instructions specific to this package. Some packages provide this +'INSTALL' file but do not implement all of the features documented +below. The lack of an optional feature in a given package is not +necessarily a bug. More recommendations for GNU packages can be found +in *note Makefile Conventions: (standards)Makefile Conventions. + + The 'configure' shell script attempts to guess correct values for +various system-dependent variables used during compilation. It uses +those values to create a 'Makefile' in each directory of the package. +It may also create one or more '.h' files containing system-dependent +definitions. Finally, it creates a shell script 'config.status' that +you can run in the future to recreate the current configuration, and a +file 'config.log' containing compiler output (useful mainly for +debugging 'configure'). + + It can also use an optional file (typically called 'config.cache' and +enabled with '--cache-file=config.cache' or simply '-C') that saves the +results of its tests to speed up reconfiguring. Caching is disabled by +default to prevent problems with accidental use of stale cache files. + + If you need to do unusual things to compile the package, please try +to figure out how 'configure' could check whether to do them, and mail +diffs or instructions to the address given in the 'README' so they can +be considered for the next release. If you are using the cache, and at +some point 'config.cache' contains results you don't want to keep, you +may remove or edit it. + + The file 'configure.ac' (or 'configure.in') is used to create +'configure' by a program called 'autoconf'. You need 'configure.ac' if +you want to change it or regenerate 'configure' using a newer version of +'autoconf'. + + The simplest way to compile this package is: + + 1. 'cd' to the directory containing the package's source code and type + './configure' to configure the package for your system. + + Running 'configure' might take a while. While running, it prints + some messages telling which features it is checking for. + + 2. Type 'make' to compile the package. + + 3. Optionally, type 'make check' to run any self-tests that come with + the package, generally using the just-built uninstalled binaries. + + 4. Type 'make install' to install the programs and any data files and + documentation. When installing into a prefix owned by root, it is + recommended that the package be configured and built as a regular + user, and only the 'make install' phase executed with root + privileges. + + 5. Optionally, type 'make installcheck' to repeat any self-tests, but + this time using the binaries in their final installed location. + This target does not install anything. Running this target as a + regular user, particularly if the prior 'make install' required + root privileges, verifies that the installation completed + correctly. + + 6. You can remove the program binaries and object files from the + source code directory by typing 'make clean'. To also remove the + files that 'configure' created (so you can compile the package for + a different kind of computer), type 'make distclean'. There is + also a 'make maintainer-clean' target, but that is intended mainly + for the package's developers. If you use it, you may have to get + all sorts of other programs in order to regenerate files that came + with the distribution. + + 7. Often, you can also type 'make uninstall' to remove the installed + files again. In practice, not all packages have tested that + uninstallation works correctly, even though it is required by the + GNU Coding Standards. + + 8. Some packages, particularly those that use Automake, provide 'make + distcheck', which can by used by developers to test that all other + targets like 'make install' and 'make uninstall' work correctly. + This target is generally not run by end users. + +Compilers and Options +===================== + + Some systems require unusual options for compilation or linking that +the 'configure' script does not know about. Run './configure --help' +for details on some of the pertinent environment variables. + + You can give 'configure' initial values for configuration parameters +by setting variables in the command line or in the environment. Here is +an example: + + ./configure CC=c99 CFLAGS=-g LIBS=-lposix + + *Note Defining Variables::, for more details. + +Compiling For Multiple Architectures +==================================== + + You can compile the package for more than one kind of computer at the +same time, by placing the object files for each architecture in their +own directory. To do this, you can use GNU 'make'. 'cd' to the +directory where you want the object files and executables to go and run +the 'configure' script. 'configure' automatically checks for the source +code in the directory that 'configure' is in and in '..'. This is known +as a "VPATH" build. + + With a non-GNU 'make', it is safer to compile the package for one +architecture at a time in the source code directory. After you have +installed the package for one architecture, use 'make distclean' before +reconfiguring for another architecture. + + On MacOS X 10.5 and later systems, you can create libraries and +executables that work on multiple system types--known as "fat" or +"universal" binaries--by specifying multiple '-arch' options to the +compiler but only a single '-arch' option to the preprocessor. Like +this: + + ./configure CC="gcc -arch i386 -arch x86_64 -arch ppc -arch ppc64" \ + CXX="g++ -arch i386 -arch x86_64 -arch ppc -arch ppc64" \ + CPP="gcc -E" CXXCPP="g++ -E" + + This is not guaranteed to produce working output in all cases, you +may have to build one architecture at a time and combine the results +using the 'lipo' tool if you have problems. + +Installation Names +================== + + By default, 'make install' installs the package's commands under +'/usr/local/bin', include files under '/usr/local/include', etc. You +can specify an installation prefix other than '/usr/local' by giving +'configure' the option '--prefix=PREFIX', where PREFIX must be an +absolute file name. + + You can specify separate installation prefixes for +architecture-specific files and architecture-independent files. If you +pass the option '--exec-prefix=PREFIX' to 'configure', the package uses +PREFIX as the prefix for installing programs and libraries. +Documentation and other data files still use the regular prefix. + + In addition, if you use an unusual directory layout you can give +options like '--bindir=DIR' to specify different values for particular +kinds of files. Run 'configure --help' for a list of the directories +you can set and what kinds of files go in them. In general, the default +for these options is expressed in terms of '${prefix}', so that +specifying just '--prefix' will affect all of the other directory +specifications that were not explicitly provided. + + The most portable way to affect installation locations is to pass the +correct locations to 'configure'; however, many packages provide one or +both of the following shortcuts of passing variable assignments to the +'make install' command line to change installation locations without +having to reconfigure or recompile. + + The first method involves providing an override variable for each +affected directory. For example, 'make install +prefix=/alternate/directory' will choose an alternate location for all +directory configuration variables that were expressed in terms of +'${prefix}'. Any directories that were specified during 'configure', +but not in terms of '${prefix}', must each be overridden at install time +for the entire installation to be relocated. The approach of makefile +variable overrides for each directory variable is required by the GNU +Coding Standards, and ideally causes no recompilation. However, some +platforms have known limitations with the semantics of shared libraries +that end up requiring recompilation when using this method, particularly +noticeable in packages that use GNU Libtool. + + The second method involves providing the 'DESTDIR' variable. For +example, 'make install DESTDIR=/alternate/directory' will prepend +'/alternate/directory' before all installation names. The approach of +'DESTDIR' overrides is not required by the GNU Coding Standards, and +does not work on platforms that have drive letters. On the other hand, +it does better at avoiding recompilation issues, and works well even +when some directory options were not specified in terms of '${prefix}' +at 'configure' time. + +Optional Features +================= + + If the package supports it, you can cause programs to be installed +with an extra prefix or suffix on their names by giving 'configure' the +option '--program-prefix=PREFIX' or '--program-suffix=SUFFIX'. + + Some packages pay attention to '--enable-FEATURE' options to +'configure', where FEATURE indicates an optional part of the package. +They may also pay attention to '--with-PACKAGE' options, where PACKAGE +is something like 'gnu-as' or 'x' (for the X Window System). The +'README' should mention any '--enable-' and '--with-' options that the +package recognizes. + + For packages that use the X Window System, 'configure' can usually +find the X include and library files automatically, but if it doesn't, +you can use the 'configure' options '--x-includes=DIR' and +'--x-libraries=DIR' to specify their locations. + + Some packages offer the ability to configure how verbose the +execution of 'make' will be. For these packages, running './configure +--enable-silent-rules' sets the default to minimal output, which can be +overridden with 'make V=1'; while running './configure +--disable-silent-rules' sets the default to verbose, which can be +overridden with 'make V=0'. + +Particular systems +================== + + On HP-UX, the default C compiler is not ANSI C compatible. If GNU CC +is not installed, it is recommended to use the following options in +order to use an ANSI C compiler: + + ./configure CC="cc -Ae -D_XOPEN_SOURCE=500" + +and if that doesn't work, install pre-built binaries of GCC for HP-UX. + + HP-UX 'make' updates targets which have the same time stamps as their +prerequisites, which makes it generally unusable when shipped generated +files such as 'configure' are involved. Use GNU 'make' instead. + + On OSF/1 a.k.a. Tru64, some versions of the default C compiler cannot +parse its '' header file. The option '-nodtk' can be used as a +workaround. If GNU CC is not installed, it is therefore recommended to +try + + ./configure CC="cc" + +and if that doesn't work, try + + ./configure CC="cc -nodtk" + + On Solaris, don't put '/usr/ucb' early in your 'PATH'. This +directory contains several dysfunctional programs; working variants of +these programs are available in '/usr/bin'. So, if you need '/usr/ucb' +in your 'PATH', put it _after_ '/usr/bin'. + + On Haiku, software installed for all users goes in '/boot/common', +not '/usr/local'. It is recommended to use the following options: + + ./configure --prefix=/boot/common + +Specifying the System Type +========================== + + There may be some features 'configure' cannot figure out +automatically, but needs to determine by the type of machine the package +will run on. Usually, assuming the package is built to be run on the +_same_ architectures, 'configure' can figure that out, but if it prints +a message saying it cannot guess the machine type, give it the +'--build=TYPE' option. TYPE can either be a short name for the system +type, such as 'sun4', or a canonical name which has the form: + + CPU-COMPANY-SYSTEM + +where SYSTEM can have one of these forms: + + OS + KERNEL-OS + + See the file 'config.sub' for the possible values of each field. If +'config.sub' isn't included in this package, then this package doesn't +need to know the machine type. + + If you are _building_ compiler tools for cross-compiling, you should +use the option '--target=TYPE' to select the type of system they will +produce code for. + + If you want to _use_ a cross compiler, that generates code for a +platform different from the build platform, you should specify the +"host" platform (i.e., that on which the generated programs will +eventually be run) with '--host=TYPE'. + +Sharing Defaults +================ + + If you want to set default values for 'configure' scripts to share, +you can create a site shell script called 'config.site' that gives +default values for variables like 'CC', 'cache_file', and 'prefix'. +'configure' looks for 'PREFIX/share/config.site' if it exists, then +'PREFIX/etc/config.site' if it exists. Or, you can set the +'CONFIG_SITE' environment variable to the location of the site script. +A warning: not all 'configure' scripts look for a site script. + +Defining Variables +================== + + Variables not defined in a site shell script can be set in the +environment passed to 'configure'. However, some packages may run +configure again during the build, and the customized values of these +variables may be lost. In order to avoid this problem, you should set +them in the 'configure' command line, using 'VAR=value'. For example: + + ./configure CC=/usr/local2/bin/gcc + +causes the specified 'gcc' to be used as the C compiler (unless it is +overridden in the site shell script). + +Unfortunately, this technique does not work for 'CONFIG_SHELL' due to an +Autoconf limitation. Until the limitation is lifted, you can use this +workaround: + + CONFIG_SHELL=/bin/bash ./configure CONFIG_SHELL=/bin/bash + +'configure' Invocation +====================== + + 'configure' recognizes the following options to control how it +operates. + +'--help' +'-h' + Print a summary of all of the options to 'configure', and exit. + +'--help=short' +'--help=recursive' + Print a summary of the options unique to this package's + 'configure', and exit. The 'short' variant lists options used only + in the top level, while the 'recursive' variant lists options also + present in any nested packages. + +'--version' +'-V' + Print the version of Autoconf used to generate the 'configure' + script, and exit. + +'--cache-file=FILE' + Enable the cache: use and save the results of the tests in FILE, + traditionally 'config.cache'. FILE defaults to '/dev/null' to + disable caching. + +'--config-cache' +'-C' + Alias for '--cache-file=config.cache'. + +'--quiet' +'--silent' +'-q' + Do not print messages saying which checks are being made. To + suppress all normal output, redirect it to '/dev/null' (any error + messages will still be shown). + +'--srcdir=DIR' + Look for the package's source code in directory DIR. Usually + 'configure' can determine that directory automatically. + +'--prefix=DIR' + Use DIR as the installation prefix. *note Installation Names:: for + more details, including other options available for fine-tuning the + installation locations. + +'--no-create' +'-n' + Run the configure checks, but stop before creating any output + files. + +'configure' also accepts some other, not widely useful, options. Run +'configure --help' for more details. diff --git a/Makefile.am b/Makefile.am new file mode 100644 index 0000000..ad76876 --- /dev/null +++ b/Makefile.am @@ -0,0 +1,17 @@ +AUTOMAKE_OPTIONS = gnu

The options + -z, --suspendable, and 'set suspendable' are obsolete and ignored. + (In case you want to be able to suspend nano with a single keystroke, + you can put 'bind ^Z suspend main' in your nanorc.) +• When automatic hard-wrapping is in effect, pasting just a few words + (without a line break) will now hard-wrap the line when needed. +• Toggling Append or Prepend clears the current filename. +• The word count as shown by M-D is now affected by option --wordbounds; + with it, nano counts words as 'wc' does; without it (the new default), + words are counted in a more human way: seeing punctuation as space. +• The YAML syntax file is now actually included in the tarball. + + +2021.10.06 - GNU nano 5.9 "El manicomio ha decidido: mañana sol!" +• The extension of a filename is added to the name of a corresponding + temporary file, so that spell checking a C file, for example, will + check only the comments and strings (when using 'aspell'). +• The process number is added to the name of an emergency save file, + so that when multiple nanos die they will not fight over a filename. +• Undoing a cutting operation will restore an anchor that was located + in the cut area to its original line. +• When using --locking, saving a new buffer will create a lock file. +• Syntax highlighting for YAML files has been added. + +2021.06.15 - GNU nano 5.8 "Why is it necessary to be special?" +• After a search, the spotlighting is dropped after 1.5 seconds (0.8 + seconds with --quick) to avoid the idea that the text is selected. +• A + and a space before a filename on the command line will put the + cursor at the end of the corresponding buffer. +• Linter messages no longer include filename and line/column numbers. +• Color name "grey" or "gray" can be used instead of "lightblack". +• The color of the minibar can be chosen with 'set minicolor'. + +2021.04.29 - GNU nano 5.7 "Toți ceilalți arau câmpurile" +• The output of --constantshow (without --minibar) is more stable. +• When opening multiple buffers and there is an error message, this + message is shown again upon first switch to the relevant buffer. +• The position and size of the indicator now follow actual lines, + instead of visual lines when in softwrap mode, meaning that the + size of the indicator can change when scrolling in softwrap mode. + +2021.03.03 - GNU nano 5.6.1 "Geelgors" +• Search matches are properly colorized in softwrap mode too. +• Option 'highlightcolor' has been renamed to 'spotlightcolor'. + +2021.02.24 - GNU nano 5.6 "Wielewaal" +• A search match gets highlighted (in black on yellow by default), + in addition to placing the cursor at the start of the match. + The color combination can be changed with 'set highlightcolor'. + By default the cursor is hidden until the next keystroke, but + it can be forced on with --showcursor / 'set showcursor'. +• Option --markmatch / 'set markmatch' has been removed. +• Cursor position and character code are displayed in the minibar + only when option --constantshow / 'set constantshow' is used, + and their display can be toggled with M-C. +• The state flags are displayed in the minibar only when option + --stateflags / 'set stateflags' is used. + +2021.01.14 - GNU nano 5.5 "Rebecca" +• Option 'set minibar' makes nano suppress the title bar and instead + show a bar with basic editing information at the bottom: file name + (plus an asterisk when the buffer is modified), the cursor position + (line,column), the character under the cursor (U+xxxx), the flags + that --stateflags normally shows, plus the percentage of the buffer + that is above the cursor. +• With 'set promptcolor' the color combination of the prompt bar can + be changed, to allow contrasting it with the mini bar (which always + has the same color as the title bar). +• Option 'set markmatch' highlights the result of a successful search + by putting the mark at the end of the match, making the match more + visible. It also suppresses the cursor until the next keystroke. + (If you dislike the hiding of the cursor, use 'set showcursor'.) +• The bindable toggle 'nowrap' has been renamed to 'breaklonglines', + to match the corresponding option, like for all other toggles. +• Support for Slang has been removed. + +2020.12.02 - GNU nano 5.4 "Terre des hommes" +• Moving the cursor now skips over combining characters (and other + zero-width characters). Deleting a character deletes also any + succeeding zero-width characters, but backspacing deletes just + one character at a time. +• Workarounds for older ncurses and older libvtes were removed. + +2020.10.07 - GNU nano 5.3 "Revolution!" +• Option 'set stateflags' makes nano show the state of auto-indenting, + the mark, hard-wrapping, macro recording, and soft-wrapping in the + title bar. The flags take the place of "Modified", and a modified + buffer is instead indicated by an asterisk (*) after its name. +• Nano no longer by default tries using libmagic to determine the type + of a file (when neither filename nor first line gave a clue), because + in most cases it is a waste of time. It requires using the option + --magic or -! or 'set magic' to make nano try libmagic. +• The color of the indicator can be changed with 'set scrollercolor'. + +2020.08.24 - GNU nano 5.2 "Ranrapalca" +• Making certain replacements after a large paste does not crash. +• Hitting a toggle at the Search prompt does not clear the answer. +• Using --positionlog does not complain at the first start. +• A macro containing a Search command will not sometimes fail. + +2020.08.12 - GNU nano 5.1 "Cantabria" +• M-Bsp (Alt+Backspace) deletes a word backwards, like in Bash. +• M-[ has become bindable. (Be careful, though: as it is the + starting combination of many escape sequences, avoid gluing + it together with other keystrokes, like in a macro.) +• With --indicator and --softwrap, the first keystroke in an + empty buffer does not crash. +• Invoking the formatter while text is marked does not crash. +• In UTF-8 locales, an anchor is shown as a diamond. + +2020.07.29 - GNU nano 5.0 "Among the fields of barley" +• With --indicator (or -q or 'set indicator') nano will show a kind + of scrollbar on the righthand side of the screen to indicate where + in the buffer the viewport is located and how much it covers. +• With any line can be "tagged" with an anchor, and + and will jump to the nearest anchor. + When using line numbers, an anchor is shown as "+" in the margin. +• The Execute Command prompt is now directly accessible from the + main menu (with ^T, replacing the Spell Checker). The Linter, + Formatter, Spell Checker, Full Justification, Suspension, and + Cut-Till-End functions are available in this menu too. +• On terminals that support at least 256 colors, nine new color + names are available: pink, purple, mauve, lagoon, mint, lime, + peach, orange, and latte. These do not have lighter versions. +• For the color names red, green, blue, yellow, cyan, magenta, + white, and black, the prefix 'light' gives a brighter color. + Prefix 'bright' is deprecated, as it means both bold AND light. +• All color names can be preceded with "bold," and/or "italic," + (in that order) to get a bold and/or italic typeface. +• With --bookstyle (or -O or 'set bookstyle') nano considers any + line that begins with whitespace as the start of a paragraph. +• Refreshing the screen with ^L now works in every menu. +• In the main menu, ^L also centers the line with the cursor. +• Toggling the help lines with M-X now works in all menus except + in the help viewer and the linter. +• At a filename prompt, the first lists the possibilities, + and these are listed near the bottom instead of near the top. +• Bindable function 'curpos' has been renamed to 'location'. +• Long option --tempfile has been renamed to --saveonexit. +• Short option -S is now a synonym of --softwrap. +• The New Buffer toggle (M-F) has become non-persistent. Options + --multibuffer and 'set multibuffer' still make it default to on. +• Backup files will retain their group ownership (when possible). +• Data is synced to disk before "... lines written" is shown. +• The raw escape sequences for F13 to F16 are no longer recognized. +• Distro-specific syntaxes, and syntaxes of less common languages, + have been moved down to subdirectory syntax/extra/. The affected + distros and others may wish to move wanted syntaxes one level up. +• Syntaxes for Markdown, Haskell, and Ada were added. + + +2020.05.23 - GNU nano 4.9.3 "Almendras" +• One more bug introduced in version 4.9 is fixed: a crash when + the terminal screen is resized while at a lock-file prompt. + +2020.04.07 - GNU nano 4.9.2 "Mali Lošinj" +• Another bug introduced in version 4.9 is fixed: a likely crash + after undoing an at the end of leading whitespace. + +2020.03.31 - GNU nano 4.9.1 "Sapperdeflap" +• Two bugs introduced in version 4.9 are fixed: the cursor + getting misplaced when undoing line cuts, and filtering + of the whole buffer to a new buffer not working. + +2020.03.24 - GNU nano 4.9 "die fetten Jahre sind vorbei" +• When justifying a selection, the new paragraph and the + succeeding one get the appropriate first-line indent. +• Trying to justify an empty selection does not crash. +• Redoing the insertion of an empty file does not crash. +• On the BSDs and macOS, ^H has become rebindable again + (in most terminal emulators, not on the console). +• DOS line endings in nanorc files are accepted. +• Option --suspend / 'set suspend' has been renamed to + the more logical --suspendable / 'set suspendable'. + +2020.02.07 - GNU nano 4.8 "Jaška" +• When something is pasted into nano, auto-indentation is suppressed, + and the paste can be undone as a whole with a single M-U. +• When a lock file is encountered during startup, pressing ^C/Cancel + quits nano. (Pressing 'No' just skips the file and continues.) +• Shift+Meta+letter key combos can be bound with 'bind Sh-M-letter'. + Making any such binding dismisses the default behavior of ignoring + Shift for all Meta+letter keystrokes. +• The configuration option --with-slang (to be avoided when possible) + can now be used only together with --enable-tiny. +• A custom nanorc file can be specified on the command line, with + -f filename or --rcfile=filename. + +2019.12.23 - GNU nano 4.7 "Havikskruid" +• A will indent a marked region only when mark and cursor are + on different lines. +• Two indentations (any mix of tabs and spaces) are considered the + same when they look the same (that is: indent to the same level). +• When using --breaklonglines or ^J, a line will never be broken in + its leading whitespace or quoting. +• The keywords in nanorc files must be in lowercase. + +2019.11.29 - GNU nano 4.6 "And don't you eat that yellow snow" +• The 'formatter' command has returned, bound by default to M-F. + It allows running a syntax-specific command on the contents of + the buffer. +• ^T will try to run 'hunspell' before 'spell', because it checks + spelling for the locale's language and understands UTF-8. +• Multiple errors or warnings on startup will no longer slow nano + down but will be indicated on the status bar with trailing dots. + +2019.10.04 - GNU nano 4.5 "Košice" +• The new 'tabgives' command allows you to specify per syntax what + the key should produce: some spaces, a hard TAB, ... +• The output of --help is properly aligned again for all languages. +• will indent a marked region also when M-} has been rebound. + +2019.08.25 - GNU nano 4.4 "Hagelslag" +• At startup, the cursor can be put on the first or last occurrence + of a string by preceding the filename with +/string or +?string. +• When automatic hard-wrapping occurs (--breaklonglines), any leading + quoting characters will be automatically copied to the new line. +• M-6 works again also when the cursor is at end of buffer. + +2019.06.18 - GNU nano 4.3 "Musa Kart" +• The ability to read from and write to a FIFO has been regained. +• Opening a file no longer triggers an inotify CLOSE_WRITE event. +• Startup time is reduced by fully parsing a syntax only when needed. +• Asking for help (^G) when using --operatingdir does not crash. +• The reading of a huge or slow file can be stopped with ^C. +• Cut, zap, and copy operations are undone separately when intermixed. +• M-D reports the correct number of lines (zero for an empty buffer). + +2019.04.24 - GNU nano 4.2 "Tax the rich, pay the teachers" +• The integrated spell checker does not crash when 'spell' is missing. +• Option --breaklonglines works also when --ignorercfiles is used. +• Automatic hard-wrapping is more persistent in pushing words to the + same overflow line. + +2019.04.15 - GNU nano 4.1 "Qué corchos será eso?" +• By default, a newline character is again automatically added at the + end of a buffer, to produce valid POSIX text files by default, but + also to get back the easy adding of text at the bottom. +• The now unneeded option --finalnewline (-f) has been removed. +• Syntax files are read in alphabetical order when globbing, so that + the precedence of syntaxes becomes predictable. +• In the C syntax, preprocessor directives are highlighted differently. +• M-S now toggles soft wrapping, and M-N toggles line numbers. +• The jumpy-scrolling toggle has been removed. +• The legacy keystrokes ^W^Y and ^W^V are recognized again. +• Executing an external command is disallowed when in view mode. +• Problems with resizing during external or speller commands were fixed. + +2019.03.24 - GNU nano 4.0 "Thy Rope of Sands" +• An overlong line is no longer automatically hard-wrapped. +• Smooth scrolling (one line at a time) has become the default. +• A newline character is no longer automatically added at end of buffer. +• The line below the title bar is by default part of the editing space. +• Option --breaklonglines (-b) turns automatic hard-wrapping back on. +• Option --jumpyscrolling (-j) gives the chunky, half-screen scrolling. +• Option --finalnewline (-f) brings back the automatic newline at EOF. +• Option --emptyline (-e) leaves the line below the title bar unused. +• and now do a linewise scroll instead of a findnext. +• Any number of justifications can be undone (like all other operations). +• When marked text is justified, it becomes a single, separate paragraph. +• Option --guidestripe= draws a vertical bar at the given column. +• Option --fill= no longer turns on automatic hard-wrapping. +• When a line continues offscreen, it now ends with a highlighted ">". +• The halves of a split two-column character are shown as "[" and "]". +• A line now scrolls horizontally one column earlier. +• The bindable functions 'cutwordleft' and 'cutwordright' were renamed + to 'chopwordleft' and 'chopwordright' as they don't use the cutbuffer. +• The paragraph-jumping functions were moved from Search to Go-to-Line. +• Option --rebinddelete is able to compensate for more misbindings. +• Options --morespace and --smooth are obsolete and thus ignored. +• The --disable-wrapping-as-root configure option was removed. + + +2018.11.11 - GNU nano 3.2 "Het kromme hout" changes the default binding + for the linter to M-B so that the spell checker (^T) can + always be used, and changes (when linting) the text in the + title bar and the color of the status bar to make linting + mode more obvious. It also adds a bindable 'zap' function + for deleting a line or marked region without changing the + cutbuffer, adds --zap to bind the and + keys to the zap function when something is marked, and + hard-binds to 'zap'. Furthermore, it shows the + cursor also in the help viewer (when --showcursor is used), + renames the bindable functions 'prevhistory' to 'older' and + 'nexthistory' to 'newer' (update your nanorcs when needed), + reads the nanorc files also in restricted mode to allow + customization by the user (if this should not be allowed, + use --ignorercfiles in addition to --restricted), allows + in view mode to open also other files (if this should not + be allowed, use --restricted in addition to --view), makes + resizes respect a relative --fill again, no longer binds + F13...F15 by default, properly re-highlights a misspelled + word after invoking help in the internal spell checker, + and does not skip Unicode characters in string binds. + +2018.09.18 - GNU nano 3.1 "Je faisais des bonds comme ça!" fixes a + misbinding of ^H on some terminals and some systems, + does not leave stray stuff after the prompt upon exit + when having suspended nano while using --constantshow, + and does not allow to toggle to Replace in view mode. + +2018.09.09 - GNU nano 3.0 "Water Flowing Underground" speeds up the + reading of a file by seventy percent, roughly doubles the + speed of handling ASCII text, changes the way words at line + boundaries are deleted, makes wipe the next + word and the preceding word, binds M-Q + to 'findprevious' by default (the Tabs-to-Spaces toggle is + placed on M-O, and the More-Space toggle is fully removed), + makes an external spell check undoable, shows the correct + number of lines on the status bar when opening multiple + files, removes the 'formatter' command, removes the + 'searchagain' bindable function (M-W is now bound to + 'findnext' by default), moves the No-Convert toggle to the + Insert menu, removes the Backup and New-Buffer toggles from + the main menu (they remain in the Write-Out and Insert + menus, respectively), is more precise in what it accepts as + a rebindable key name, ignores any presses of before + a valid command keystroke, recognizes some more escape + sequences for modified editing-pad keys, does not hide + rcfile error messages on a Linux console, renames the + bindable functions 'copytext' to 'copy' and 'uncut' to + 'paste', and avoids a possible hang during a Full-Justify. + + +2018.06.02 - GNU nano 2.9.8 "Espresso" brings the ability to filter the + buffer (or the marked region) through an external command + (^R^X and prefix the command with the pipe symbol, "|"), is + better at detecting and maintaining paragraphs, is able to + justify //-style comments, fixes a crash when the binding + of a key to a string lacks a closing quote, gives feedback + about the number of lines written also when prepending or + appending, and fixes a couple of bugs with the linter. + +2018.05.15 - GNU nano 2.9.7 "Hvide Sande" adds the option '--afterends' + for making Ctrl+Right (the nextword function) stop at word + ends instead of beginnings, accepts multibyte letters for + the Yes/No/All answers, does emergency saves of changed + buffers in the unlikely event that nano crashes, adds the + until-now missing bindable function 'linenumbers', and + renames the toggles 'constupdate' to 'constantshow' and + 'cuttoend' to 'cutfromcursor', for consistency with the + corresponding options -- adjust your nanorc files soon. + +2018.04.27 - GNU nano 2.9.6 "Gomance" fixes a crash in word completion, + makes --enable-altrcname work again, improves the fluidity + of scrolling when using the touchpad, tweaks the syntaxes + for shell scripts and PO files, makes a replacing session + go always forward by default, no longer inserts a newline + after an external spell check of a selected region, always + accepts the English Y and N (and A) at a yes-no prompt in + any locale, and solves a few hypothetical bugs. + +2018.03.29 - GNU nano 2.9.5 "Kiša pada" changes the way the Scroll-Up + and Scroll-Down commands work (M-- and M-+): instead of + keeping the cursor in the same screen position they now + keep the cursor in the same text position (if possible). + This version further adds a new color name, "normal", + which gives the default foreground or background color, + which is useful when you want to undo some overzealous + painting by earlier syntax regexes. Bug fixes include: + a segfault when trying to insert a file in restricted + mode, the reading in of a new file being "undoable", a + slight miswrapping of help texts when --linenumbers was + used, and the shell syntax coloring the word "tar" in + file names. + +2018.03.08 - GNU nano 2.9.4 "Isabel" allows binding a key to a string + (any piece of text and/or commands), permits customizing + the color of error messages with 'set errorcolor', colors + those error messages by default in bright white on red, + makes at the bottom of the screen scroll just one + row when --smooth is used, does not fail when redoing a + file insertion, and cancels a Shift-selection when any + cursor key is pressed without Shift even when the cursor + cannot move. Further, it treats tabs fully the same as + spaces when doing automatic hard-wrapping, allows syntax + names to be unquoted, and removes two deprecated options + and six deprecated bindable function names. + +2018.01.29 - GNU nano 2.9.3 "Córdoba" fixes a segfault with trimblanks + that could occur when a typed space caused the word after + it to be pushed to the next line. It further makes macros + work also when your keyboard still emits escape sequences, + adds the options -M and --trimblanks for the command line, + recognizes key combos with Shift on a few more terminals, + no longer shows dots in certain prompt texts when visible + whitespace is turned on, fixes two corner cases when doing + replacements in a marked region, allows to open a named + pipe again when using --noread, and accurately detects + a needed color change when a line contains a start match + but not a corresponding end match any more. Plus some + other small fry. + +2018.01.02 - GNU nano 2.9.2 "Pussy Riot" correctly displays the Modified + state when undoing/redoing (also when the file was saved + somewhere midway), improves the undoing of an automatic + linefeed at EOF, fixes a build issue on the BSDs, shows + the cursor again when compiled with --withslang, renames + the option 'justifytrim' to 'trimblanks' because it will + now snip trailing whitespace also while you are typing + (and hard-wrapping is enabled), continues pushing words + to the next line much longer (when hard-wrapping), makes + and indent and unindent a marked region, + allows unindenting when not all lines are indented, lets a + region marked with Shift persist when indenting/unindenting + or commenting/uncommenting it, and in those cases excludes + the last line of the region when it is not visibly marked + (which makes for a more intuitive behavior). + +2017.11.27 - GNU nano 2.9.1 "Damyatta" fixes a bug where, when the mark + is on, ^S would overwrite the file with just the marked + region. This release further clears the "Modified" flag + when all edits are undone, adds or updates some magic + strings, and does not forget when the cursor was last + at line 1, column 1. + +2017.11.18 - GNU nano 2.9.0 "Eta" introduces the ability to record and + replay keystrokes (M-: to start and stop recording, M-; + to play the macro back), makes ^Q and ^S do something + useful by default (^Q starts a backward search, and ^S + saves the current file), changes ^W to start always a + forward search, shows the number of open buffers (when + more than one) in the title bar, no longer asks to press + Enter when there are errors in an rc file, retires the + options '--quiet' and 'set quiet' and 'set backwards', + makes indenting and unindenting undoable, will look in + $XDG_CONFIG_HOME for a nanorc file and in $XDG_DATA_HOME + for the history files, adds a history stack for executed + commands (^R^X), does not overwrite the position-history + file of another nano, and fixes a score of tiny bugs. + + +2017.08.27 - GNU nano 2.8.7 "Fragrance" fixes a lockup when tabs are + wider than the screen, makes indenting + unindenting + more predictable by retaining relative indentations, + allows pasting (^U) at a prompt, allows triple quotes + in Python to not be followed by a character, does not + scroll three pages on a roll of the mouse wheel, binds + Alt+Up and Alt+Down to findprevious and findnext, and + fixes some hard-to-describe issues with softwrapping + and boundary-crossing tabs. Enjoy. + +2017.07.21 - GNU nano 2.8.6 "Kekulé" offers a new feature: the ability + to do softwrapping between words -- at whitespace -- + instead of always at the edge of the screen. This can + be activated with -a or --atblanks or 'set atblanks' + together with the softwrap option. This release further + fixes a handful of rare display glitches, fixes a build + failure on AIX, harmonizes the quoting rules in the rc + files, and renames the option 'cut' to 'cutfromcursor' + (please update your nanorc files before 2020). + +2017.06.25 - GNU nano 2.8.5 "Farouche" avoids a crash when waking from + a suspension that was induced from the outside, allows + negative line and column numbers on the command line, + avoids some flickering when resizing the screen while + in the file browser, opens files in the order they were + mentioned on the command line, and does not pretend to + have woken from suspension when receiving a SIGCONT. + +2017.05.21 - GNU nano 2.8.4 "Our Version of Events" includes the nanorc + man page again. + +2017.05.18 - GNU nano 2.8.3 "Hirsch" fixes a misplacement of the spotlight + during interactive replacing, avoids build failures on AIX + and Solaris, fixes a crash on Solaris, speeds up backwards + searching, improves PHP syntax highlighting, and no longer + asks “save anyway?” when the user ^Q discards the buffer. + +2017.05.04 - GNU nano 2.8.2 "Krats" adds another new feature: it makes + the ^G help texts searchable with ^W. Apart from that, + it fixes a crash when resizing the window in the middle + of verbatim input, avoids an unlikely crash when used + without UTF-8 support in some locales, avoids redrawing + the screen twice when switching between buffers while + line numbers are active, and works around a coloring + bug on musl. Plus tweaks to the documentation; plus + translation updates for fifteen languages. + +2017.04.12 - GNU nano 2.8.1 "Ellert" fixes build failures on MacOS and + on musl, fixes scrolling problems in softwrap mode when + double-width characters on row boundaries are involved, + shows double-width characters as ">" and "<" when split + across two rows, moves the cursor more predictably (at + the cost of sometimes putting it on the second "half" + of a character), avoids creating lines that consist of + only blanks when using autoindent, makes ^Home and ^End + go to the start and end of the file (on terminals that + support those keystrokes), places the cursor better when + linting, lets the linter ask only once whether to open + an included file, and adds bindings for ^Up and ^Down + in the file browser. Don't sit on your hands. + +2017.03.31 - GNU nano 2.8.0 "Axat" makes it easier to move around in + softwrapped lines: the Up and Down keys now step from + visual row to visual row instead of jumping between + logical lines, and the Home and End keys now move to + the start and end of a row, and only when already + there, then to the start and end of the logical line. + Furthermore, the screen can now scroll per row instead + of always per logical line. On an entirely different + front: nano now makes use of gnulib, to make it build + on more platforms. In short: there were many internal + changes, not many user-visible ones (apart from the + new softwrap navigation). The conversion to gnulib + was done by Mike Frysinger, the softwrap overhaul by + David Ramsey. + + +2017.02.23 - GNU nano 2.7.5 "Nijntje" can properly search and replace + the \B and \b regex anchors, correctly repaints things + when multiline regexes with identical start and end are + involved, fixes a crash with zero-length regex matches, + does replacements at the edges of a marked region right, + no longer hides double-width characters at the head of + softwrapped rows, displays at most three warnings at + startup, and documents the ability to read a file from + standard input. Come tickle my ears. + +2017.01.10 - GNU nano 2.7.4 "Red dress" undoes deletions in an orderly + manner again (bug was introduced in previous version), + sets the preferred x position for vertical movements + more consistently, avoids some scrolling problems in + softwrap mode, installs the Info manual also when your + system lacks 'makeinfo', and corrects the behavior of + the beginning-of-word anchor (\<) in regex searches. + +2016.12.28 - GNU nano 2.7.3 "Ontbijtkoek" wipes away a handful of bugs: + your editor is now able to handle filenames that contain + newlines, avoids a brief flash of color when switching + between buffers that are governed by different syntaxes, + makes the Shift+Ctrl+Arrow keys select text again on a + Linux console, is more resistant against malformations + in the positionlog file, and does not crash when ^C is + typed on systems where it produces the code KEY_CANCEL. + Oh, and it no longer mistakenly warns about editing an + unlocked file just after saving a new one. That's it. + Tastes great with thick butter. + +2016.12.12 - GNU nano 2.7.2 "Shemesh! Shemesh!" brings another feature: + the ability to complete with one keystroke (^] by default) + a fragment of a word to a full word existing elsewhere in + the current buffer. Besides, this release fixes two bugs + related to using line numbers in softwrap mode, allows to + use the PageUp and PageDown keys together with Shift on + VTE-based terminals, stops the help lines from flickering + during interactive replacing, makes a 'set fill' override + an earlier 'set nowrap', properly restores the selected + region after an external spell check, and improves a few + other tidbits. If you should find any more bugs, please + run 'man nano | grep bugs' and report them there. + +2016.10.29 - GNU nano 2.7.1 "Leuven" adds an often-asked-for feature: the + ability to display line numbers beside the text. This can + be activated with -l or --linenumbers on the command line, + or with 'set linenumbers' in your nanorc, or toggled with + M-#. The coloring of these numbers can be chosen via the + option 'set numbercolor'. This release furthermore fixes + some bugs with scrolling in softwrap mode, is more strict + in the parsing of key rebindings, and marks a new buffer + as modified when the output of a command (^R^X) has been + read into it. Come and check it out! + +2016.09.01 - GNU nano 2.7.0 "Suni" adds a new feature: allowing text to + be selected by holding Shift together with the cursor keys. + Besides that, nano now works also when run in very tiny + terminals (down to one line, one column), and improves + the handling of the prompt in cramped spaces. Not much, + but it's time to get it out there. + + +2016.08.10 - nano 2.6.3 "Marika" makes the Ctrl+Arrow keys work also on + a Linux virtual console, takes as verbatim only the very + first keystroke after M-V, removes any lock files that it + holds when dying, doesn't abort when a word contains digits + (when using the default speller), fixes a small sorting bug + in the file browser, makes searching case-insensitively in + a UTF-8 locale a little faster, and doesn't enter invalid + bytes when holding down both Alt keys. Santé! + +2016.07.28 - nano 2.6.2 "Le vent nous portera" adds two new features: the + keystrokes Ctrl+Up and Ctrl+Down for jumping between blocks + of text, and the option 'wordchars' for specifying which + characters (beside alphanumeric ones) should be considered + word-forming. Further, it provides feedback during Unicode + input (M-V followed by a six-digit hexadecimal number which + must start with 0 or 10), avoids a crash when resizing the + window during Verbatim input, doesn't drop a keystroke after + having been suspended, and replaces the beginning-of-line + anchor (^) just once per line. There are also several tiny + improvements in screen rendering and key handling. Come get + your hair tousled! + +2016.06.27 - nano 2.6.1 "Stampede" is chiefly a translation update, but + also adds one little feature (the ability to use negative + numbers with Go To Line: -1 meaning the first line from the + bottom), includes syntax highlighting for Rust, and fixes + three tiny bugs (but in such far corners of the editor that + they aren't even worth mentioning). + +2016.06.17 - nano 2.6.0 "Rubicon" fixes more than fifty little bugs -- + and some of them not so little. It improves moving about + in the file browser, corrects failings of the internal spell + checker, adds a new feature (comment/uncomment lines, with + default binding M-3), makes some error messages clearer, + shows more of a file when positionlog is used and the cursor + is near the end, displays all error messages at startup if + there are multiple ones, does not misinterpret keystrokes + when typing very fast, is less eager to trim the filename + on narrow terminals, speeds up case-insensitive searches, + and allows to abort re-searches. Among bunches of other + things. It is worth the trouble to upgrade. + + +2016.02.25 - GNU nano 2.5.3 "Alphys" is released. This release contains + fixes for bugs like: stray cursor positioning errors, many + many memory leaks including during file reading, using the + file browser, searching for multibyte characters, history + completion, and many other places. + New features include the ability to trim whitespace + from the ends of lines when justifying text, see nanorc(5) + option justifytrim for deets. As always thank you for your + continued support of nano, and keep sparing. + +2016.02.12 - GNU nano 2.5.2 is carrying too many dogs. This release + includes several fixes for various memory leaks, position- + history size growth, and a long-standing issue with using + nano under sudo creating root-owned files. There are also + the usual bevy of documentation and other miscellaneous + fixes and touchups. Upgrade today while supplies last, + operators are standing by! + +2016.01.11 - GNU nano 2.5.1 "Salzburg" is released. It includes fixes + for a syntax-highlighting bug and a positionlog bug, it + disables a time-eating multiline regex in the C syntax, + and it adds an escape hatch to the WriteOut menu when + --tempfile is used: the discardbuffer command, ^Q. It + also has translation updates for fifteen languages, and + a small fix in the softwrap code. So... you are heartily + invited to upgrade. Enjoy! + +2015.12.05 - GNU nano 2.5.0 "Karma", the first release of the 2.5 series, + is now available. Please note that as of this release, + there will no longer be separate stable and unstable + branches. The development team will prioritize bug fixes + as needed, and make new releases in proportion to the + severity of the bugs which are fixed. + This release includes all of the fixes now in 2.4.3, as + well as color syntax highlighting improvements, undo fixes, + and many more improvements! Thank you for using nano! + + +2015.11.18 - GNU nano 2.4.3 "Apocalypse" is now available for your + downloading pleasure. This release includes a myriad + of fixes including several memory leaks, issues with + color syntax highlighting, search/replace, file insertion + and help menu bugs. Many thanks to Benno Schulenberg for + tireless efforts on the vast majority of fixes for some + time now. As always please report bugs via the Savannah + page, and remember to Share and Enjoy. + +2015.07.05 - GNU nano 2.4.2 "Portorož" is released. This release + includes several fixes, including the ability to resize + when in modes other than the main editing window, proper + displaying of invalid UTF-8 bytes, new syntax definitions + for Elisp, Guile, and PostgreSQL, and better display of + shortcuts in the help viewer and file browser. Thanks + for your patience and using nano! + +2015.04.14 - GNU nano 2.4.1 "Glitch Gremlin" is released. This release + includes several fixes for issues with the file browser + menu, linter and formatter functions, spell checker, + undo/redo with some specific marked-cutting situations, + and some small improvements to the color syntax + highlighting definitions. There are also various + documentation and code comment updates included, and + finally, fixes for compilation on non-GNU/Linux systems + and certain configure combinations. Toasters! + +2015.03.22 - GNU nano 2.4.0 "lizf" is released. This is the first + stable release in many years, and brings together many + new features from the 2.3 series, including: + a fully functional undo system (now enabled by default), + vim-compatible file locking, linter support, formatter + support, syntax highlighting flexibility, and many fixes + for issues reported since 2.2. Many sincere thanks + to all of the bug reports, patches, well wishes and + contributions from everyone who has continued to + support us. Thank you for using nano! + + +2015.02.27 - GNU nano 2.3.99pre3 "Ashley" is released. This is likely + to be the last release before the next major (2.4.0) + release. Please test it out and send us any feedback + via Savannah (https://savannah.gnu.org/bugs/?group=nano). + This release includes fixes for rebinding toggles via + nanorc, several memory alignment fixes, and documentation + and build updates. As always thank you for using nano - + Share and Enjoy! + +2015.02.06 - GNU nano 2.3.99pre2 "Snowblind" is released. This release + contains only fixes, including: a long-standing problem + with cutting in nano-tiny, several memory alignment + improvements, and issues with leftover file locks. Please + keep reporting bugs so we can get a happy and healthy + 2.4.0 soon. Thanks for using nano! + +2015.01.06 - GNU nano 2.3.99pre1 "Junior" is released. As the first + 2.4 release candidate there will be fewer new features + but many bugfixes going forward. This release contains + new support for language reformatters like Go's gofmt + command which takes the place of the spelling checker. + Fixes in this release include many syntax highlighting + fixes and improvements, and documentation formatting updates. + As always please report bugs via the Savannah bug page for + nano (https://savannah.gnu.org/bugs/?group=nano), so we can + release a super awesome and bug-free 2.4.0 soon! + +2014.07.17 - GNU nano 2.3.6 "Columbo" is released. This release + contains a fix for installing internationalization + files. Also included are scattered documentation + (in particular man page) fixes, and a few touchups + to syntax highlighting definitions. Oh, just one + more thing, thanks for using nano! + +2014.07.11 - GNU nano 2.3.5 "lucky day" is released. This release + contains many visible and under-the-hood fixes for + components such as file locking, more fixes to the + undo system, and you no longer have to explicitly ask + nano to have undo/redo support as it now defaults to + being enabled. Other notable fixes include a better + handling of --tempfile mode, and better handling of + command line arguments when also attempting to specify + +. As always, please file any bugs you + find via https://savannah.gnu.org/bugs/?group=nano + and thanks for using nano. + +2014.06.02 - GNU nano 2.3.4 won't leave you high, won't leave you dry. + This release contains only a small number of fixes, but + in particular allows nano to compile on non-UTF-8 curses + implementations (i.e. libncursesw). Other small fixes to + the undo implementation and the default syntax config are + also included. As always, Share and Enjoy! + +2014.05.28 - GNU nano 2.3.3 is in its right place. This release + contains many many improvements to the core system, + including substantial improvements to the undo/redo code, + UTF-8 handling, the configure script, and display of + shortcuts on very wide terminals. New features include + the ability to write to named pipes (--noread), as well + as linter support (see the nanorc man page for details). + Also included are much improved syntax highlighting code, + and configurations for JSON, texinfo, Go, and a default + syntax for catch-all highlighting. Finally, nano now has + the ability to set the color of the title bar, status bar, + and shortcut keys (e.g. "^X") and their descriptions. + Again see the nanorc page for details. There's much more, + too much to include here, but please keep those reports + and general feedback coming! Thank you for helping us + help you help us all. + +2013.03.22 - GNU nano 2.3.2 "Annoy your coworkers for fun and profit" is + released. This release introduces vim-style file locking + (though not backup/restore), useful when using nano in a + multi-editor environment. Feedback is welcome if you run + into any issues with this new code. Other new features + include additional support for word boundary checking when + cross compiling, fixes for trying to go to an invalid + line number, and the usual documentation tweaks. + +2011.05.10 - GNU nano 2.3.1 "I'm in space" is released. This release + includes some fixes for the new libmagic code, as well as + a fix for improper character counts when using auto-indent. + Also included are new syntax highlighting definitions for + RPM spec and Lua files. Thanks for using nano and keep + circulating the tapes. + +2011.02.26 - GNU nano 2.3.0 "Septic surprise" is released. This first + release in the 2.3 unstable series brings several new + features. First, libmagic support for syntax highlighting + has been added on top of the existing file extension and + header support already available. Secondly, cursor position + can be saved between editing sessions with the -P or --poslog + command-line flag, or via 'set poslog' in your .nanorc. Also + included are some fixes for compilation with g++, and better + handling of issues writing the backup file, which should + reduce the need for the 'set allow_insecure_backup' nanorc + option. Don't stop, get it get it, don't stop, get it get it. + + +2010.11.22 - GNU nano 2.2.6 "Pimp my BBS" wants you to go to + www.desertbus.org and donate a few bucks for the great + Child's Play Charity! This is just a small release to + update a bug where restricted mode was not particularly + restricted since key bindings were introduced. It also + signals the return of win32 builds which now feature + nanorc support; please see the FAQ for details of how + to enable it, this feature is a bit of a kludge for now. + Remember that when all else fails, USE SPACE JUMP. + +2010.08.05 - GNU nano 2.2.5 "Inactivity timeout" is now available. + This release includes slightly less restrictive checking + when writing files in strange environments (e.g. when + being used out of crontab). For very strange situations + (such as where you cannot change the permissions on the + file you're writing), there is a new rc file option + 'allow_insecure_backup' to be even more permissive and + allow the write to proceed. Also included are some + syntax highlighting updates, and that is about it. + Keep fighting the good fight children. + +2010.04.15 - GNU nano 2.2.4 is nobody's fool. First and foremost, + this release includes some security fixes due to + an assessment of nano's vulnerability to symlink attacks + on open files. The CVEs fixed with this release are + CVE-2010-1160 and CVE-2010-1161. Also included are fixes + for various crash modes when using the spell checker + on new files in multibuffer mode (surely you've used + that combination recently? no?) as well as a fixing + the 'file was modified' message when saving to a + new filename (since how would nano know?). And + the list would not be complete without our + third-times-the-charm fixes to page up/down due to + the soft wrapping code. The lone new feature + included is a new syntax highlighting definition for + cmake-related files. Please do consider upgrading to + this release if still using the 2.0 series since + fixes for that version are still forthcoming. + +2010.02.11 - GNU nano 2.2.3 "fumbling toward stability" is released. + This release contains a fix for only one bug, but a + rather irritating one: when paging up/down with smooth + scrolling, the cursor position was not being preserved + due to a bug in 2.2.2. With such a targeted fix + like this what could POSSIBLY go WRONG? Hahaha. + Enjoy and if you find new bugs, as always please + use Savannah's bug tracker. + https://savannah.gnu.org/bugs/?func=additem&group=nano + +2010.01.17 - GNU nano 2.2.2 is released for you, you, you. This + release includes fixes for: crashes when writing + backup files in certain conditions, improper + screen centering when moving up/down in various + combination of smooth scrolling and soft wrapping modes, + a search crash on the armel arch, and issues with + lots of keybinding customizations causing crashing + particularly on FreeBSD. Also included are better + help menu entries for forward/back in the file browser, + some man page tweaks and one assert fix. As always, + share and enjoy! + +2009.12.12 - GNU nano 2.2.1 "DLR strikes back" is open for business. + This release fixes many bugs, including: missing + keybindings for page up/down and GotoDir in the browser, + ^P/^N in the help menu, and restoration of M-W as the + default re-search binding. Other fixes include several + issues with compiler warnings and configure options, and + documentation updates, including the nano texinfo manual, + nano and nanorc man pages, and UPGRADE file, and some + missing syntax highlighting entries for the sample nanorc. + And no release would be complete without the latest round + of 'final' soft wrapping fixes! Finally, nano will no + longer print a warning when attempting to insert the + contents of a read-only file into an existing buffer. + Enjoy and Happy Hanukkah. + +2009.11.30 - GNU nano 2.2.0 "Doc Brown" is released! The culmination + of almost two years of development and hot on the heels + of nano's 10th birthday is available for all your editing + needs! Bugs fixed since the last release include several + fixes for tiny mode (involving both the help keys and + replace menu text), more 'final' fixes for soft wrapping, + and several typo and documentation updates including nanorc + tweaks and a new syntax highlighting file for makefiles. + Also included is a long-standing fix for random crashing + when using nanorc on FreeBSD, and nano will no longer clear + the screen on suspend to maintain compatibility with other + *nix editors. For those who haven't been playing along at + home, please see the official web page for the summary of + new features since 2.0. Special thanks to all who have + submitted bug reports recently in support of our new stable + release, and apologies for all those bugs we didn't yet + find :-) Peace to all. + + +2009.11.21 - GNU nano 2.1.99pre2 is available for a special pre-Black + Friday discount. Included are some (hopefully final) + fixes for issues with last page display caused by the + soft wrapping code, and a fix for a long-standing issue + with hitting the Home key when going through the search + history. On the features front, nano will now attempt to + retain the proper ownership and permissions when trying + to create a .save file due to receiving a signal. Nano + can now also unbind keys from one or more menus via the + 'unbind' keyword. Finally, passing --fill or --nowrap on + the command line will now override any related .nanorc + entries. Speak now or forever hold your bugs! + +2009.11.15 - GNU nano 2.1.99pre1 "take a bow" is out there, man, + it's out there all right. This release contains mainly + bugfixes, underscoring that we are preparing for the + next stable series release. Included are many fixes + for the new soft wrapping code, compiler warning tweaks, + and the modification time warning no longer triggers + when saving a file with a new name. Also included are + some fixes for various nanorc options, and there are + surely more bugs to find before we call the code base + stable, so please keep those reports coming! + +2009.09.14 - GNU nano 2.1.11 is on very thin ice, very thin ice, very + thin ice. This release includes two new features: first, + nano will check whether the current file is writable when + it is opened, and warn if it is not on the status bar. + Secondly, a new soft-wrapping (AKA full-line display) + option is available, which will attempt to fully display + the contents of lines longer than the width of the screen + without the usual truncation and a '$' symbol at the end + of the line. It can be enabled via Meta-$ inside the + editor, via the -$ or --softwrap command-line flags, + or via "set softwrap" in your .nanorc. As always, + please report any bugs to the nano Savannah project page + (https://savannah.gnu.org/bugs/?func=additem&group=nano) + Remember: data loss happens, back up your files. + +2009.07.28 - GNU nano 2.1.10 "Ellie" is released. This version includes + various fixes for portability including some older HP-UX + compiler combos, various compiler warnings, and some crash + fixes in the undo code. On the topic of the latter item, + the undo code is now marked as experimental since it can + cause severe stability and memory issues, and thus now + requires a flag (-u, --undo) in order to enable it. + Please feel free to continue to test the undo code and + thanks again for using nano for your text editing needs. + Go team Nano! + +2009.02.16 - GNU nano 2.1.9 wonders what all that glass is doing on the + floor! This release is primarily meant as a less buggy + version of 2.1.8, particularly for issues with the new + sped-up syntax highlighting code. Other fixes include + configure-time detection of groff HTML support before + attempting to generate the HTML version of man pages, + and using ~ or ~username syntax in .nanorc should now + work again. Also, nano will now only ask for one + acknowledgement of errors it encounters when parsing + nanorc files, and a new flag -q (--quiet) will silence + these messages altogether. Give it a go, and happy + birthday lenny! + +2009.02.07 - GNU nano 2.1.8 "unsafe at any speed" is released. This + release includes some long overdue performance improvements + in syntax color highlighting, the ability to abort running + searches (useful mainly when editing very large files) and + the ability to use nano like a pager for viewing standard + input (i.e. "nano -"). Additionally, there are gentoo + syntax highlighting updates and fixes for issues with + reading files in a directory with strange parent directory + permissions. The key-bindings code was also substantially + changed in order to be more ISO-C compatible. Be sure to + use the Savannah page not only for bug reports but for any + features you would like to see before the next stable + series is released. Have fun with it! + +2008.11.10 - GNU nano 2.1.7 "Effingham" is ready to make good on those + campaign promises of lower bug rates and 50% more pie. + This release includes a new check for external modifications + when saving a file, some code and documentation cleanups, + and more bug fixes for the new undo code (but we continue + to welcome your bug reports via the Savannah bug page at + https://savannah.gnu.org/bugs/?func=additem&group=nano). + Come get some. + +2008.10.03 - GNU nano 2.1.6 was for new features before it was against + them. This release includes more undo capability, several + new syntax highlighting configurations including Objective + C, OCaml, and Fortran, and a new capability to activate + highlighting based on the 1st line of the file being + edited. Also, the new default configure options now + include color syntax highlighting, .nanorc support, + multibuffer and extras. These items can still be disabled + and are not enabled with --enable-tiny. Bug fixes include + better signal handling under Cygwin, and that's about it. + Again please remember to submit bug reports via Savannah at + https://savannah.gnu.org/bugs/?func=additem&group=nano as + undo functions certainly need more testing. Bon appetit. + +2008.08.30 - GNU nano 2.1.5 is ready to lead on day one. This release + contains a better fix for incorrectly reported successful + writes on full filesystems, more helpful messages when + an internal error occurs in the undo code, and fixes for + various combinations of configure-time options and + compiler flags. Also included is new support for + changing the rc file name at configure time, and using + GNU-style regexes for word-boundaries on systems which + do not support them natively, as well as the ever popular + translation updates. Rock the tarball. + +2008.08.09 - GNU nano 2.1.4 "I told you so!" is released. This release + includes fixes for several severe issues with the new + undo/redo code. Also the behavior of writing files when + using backup mode has changed as well: if writing the + backup file fails, nano will not attempt to write the + current file. This should help folks who enjoy "extreme + text editing", i.e. editing files on file systems which + are likely to run out of space; see Savannah bug #24000. + Have fun with it! + +2008.08.04 - GNU nano 2.1.3 "least stable version ever" is released. + This release includes new (and experimental) undo and redo + functionality for most text operations. The default key + bindings are Meta-U for undo and Meta-E for redo, but these + can be remapped using the new 2.1 keybinding code. Also + included are some fixes for configuring using wide curses, + crashing when invoking the help menu with certain locales, + and not saving the search history when compiled with + configure options. + +2008.06.24 - GNU nano 2.1.2 "New York City" is released. This + release contains fixes for binding bad keys, some + configure-specific compilation failures, and more + issues with the new input back end and in particular + the status bar. Also fixed are some long-standing + issues with compiling on AIX, and a segfault when + making the terminal window too small. Rest in Peace + Tim and George! + +2008.04.01 - GNU nano 2.1.1 won't get fooled again. This release + contains fixes for the new user-rebindable keys (in + particular bracket match which was mis-bound), and + various problems with translations and configure- + related compilation problems are now fixed as well. + It also contains new syntax highlighting definitions + for Tcl, PHP, Gentoo and Debian-related files, and + some documentation updates as well. Please continue to + send reports with the key binding code to the Savannah + page (https://savannah.gnu.org/bugs/?group=nano). + +2008.03.18 - GNU nano 2.1.0 "under old mismanagement" is released. + This first release in the 2.1 development series + introduces rebindable keys for most actions inside + the editor. Please see the nanorc(5) page for more + information on configuring key bindings. Please + also report all keybinding bugs (crashes, missing + menu functions) using the Savannah bug tracker URL, + https://savannah.gnu.org/bugs/?group=nano and + thanks for sticking with us! + + +2007.12.20 - GNU nano 2.0.7 keeps its balance. This release fixes + several bugs, among others: a segfault and several + cursor positioning problems when uncutting text or + inserting files into the current buffer; a problem where + the total number of characters would be miscalculated + when replacing single-byte characters with multibyte + ones; several minor issues with the statusbar prompt + involving text display and mouse support; and several + oddities when tab-completing in the middle of a line. + It also improves autodetection of DOS and Mac format + files, properly supports the mouse wheel when using a + version of ncurses built with the --enable-ext-mouse + option, fixes some problems under NetBSD curses, adds a + lot of translation updates, and adds more minor + documentation updates. Slang curses emulation support + has also been changed to turn off all the options that + --enable-tiny does, as it's hopelessly broken otherwise. + Finally, nano is now licensed under the GNU GPL version + 3 or later, and its documentation is now dual-licensed + under the GNU GPL version 3 or later and the GNU FDL + version 1.2 or later. Have fun. + +2007.04.26 - GNU nano 2.0.6 "that was quick" is released. This release + fixes a potential segfault after justifying text marked + from the bottom up. It also adds one more minor + documentation update. Enjoy. + +2007.04.22 - GNU nano 2.0.5 braces for impact. Among other things, this + release fixes various problems (including a segfault) + when trying to open or save a file in a directory + beginning with "~" that isn't a home directory; fixes a + problem where a file with no name could be saved over an + existing filename with no warning about overwriting it; + properly disallows opening directories or device files + from "include" commands in nanorc files; no longer + displays a misleading prompt when trying to save in + restricted mode with the mark on; and properly supports + the Cancel and Shift-Cancel keys. It also improves + several color syntaxes to highlight trailing whitespace, + just as the Java syntax does, and adds yet more minor + documentation updates. Have fun. + +2007.04.06 - GNU nano 2.0.4 heralds the dawn. This release contains + proper support for the Ctrl-[arrow key], Shift-[arrow + key], and F13-F16 keys under Xfce's Terminal. It also + adds still more minor documentation updates. Enjoy. + +2007.01.29 - GNU nano 2.0.3 flows toward its ending. This release + contains several minor optimizations to make the + executable a little smaller under some circumstances, + some translation updates, improvements to the color + syntax for Python, and still more minor documentation + updates. Have fun. + +2006.12.20 - GNU nano 2.0.2 forges ahead. This release fixes a segfault + when trying to save in a nonexistent directory; fixes + handling of strings containing nulls at the "Write File", + "Insert File", "Execute Command", and "Go to Directory" + prompts; fixes several minor memory leaks; fixes two + more potential compilation warnings; adds a few + translation updates; and adds a few more minor + documentation updates. Enjoy. + +2006.11.20 - GNU nano 2.0.1 emerges from its cocoon. This release + contains several bugfixes: saving one file over another + will now always warn about overwriting it, overwriting + a file is no longer possible when saving a new file in + restricted mode, and zero-length Unicode characters are + now highlighted properly when nano is built without + regular expression support. It also adds several minor + documentation updates. Have fun with it. + +2006.11.06 - GNU nano 2.0.0 does its little dance. This release adds + documentation updates and a few cosmetic tweaks. + For those who haven't been following nano 1.3 + development, there are a ton of new features, including + support for UTF-8, moving to a specified line and column + instead of just a line, improved color syntax + highlighting, inserting previously untypeable characters + using "Verbatim Input" mode, and copying text into the + cutbuffer without cutting it. There are also fixes for + some long-standing bugs, such as the "NumLock glitch" + from nano 1.2.x, and the inability to unjustify text + after resizing. Finally, there are also a ton of + translation updates and new translations, as well as new + color syntaxes. See the UPGRADE file for more + information, and enjoy the new stable release. + + +2006.10.25 - GNU nano 1.9.99pre3 learns to appreciate life. This + release fixes a bug where the screen sometimes wouldn't + be updated properly after copying text into the + cutbuffer, fixes a potential warning while compiling, + and fixes a few other minor inconsistencies. Have fun. + +2006.10.02 - GNU nano 1.9.99pre2 crosses the threshold. This release + fixes a few more bugs: cursor positioning after leaving + the statusbar prompt has been fixed, and verbatim input + at the statusbar prompt now properly handles newlines. + Enjoy. + +2006.08.29 - GNU nano 1.9.99pre1 passes through the flames. This + release fixes various bugs in the last version: the + mouse support properly ignores everything except clicks + of the left mouse button; the statusbar is now blanked + properly when it should be; indenting and unindenting + operate on the current line when the mark is off; nano + should build on Tru64, NetBSD, and other systems that + use termcap instead of terminfo in their curses + libraries; the built-in file browser now properly + navigates file lists that take up only one row; the + cursor position is now completely restored after + inserting a file into the current buffer, and after + inserting the output of a command into a new buffer; the + ^X shortcut at the search prompt has been removed, as + official Pico doesn't include it and it's too easily + confused with Exit; the screen is updated properly after + scrolling a line without moving the cursor; the keyboard + input routines behave more consistently; and so on. + Have fun with it. + +2006.06.26 - GNU nano 1.3.12 escapes the darkness. This release + contains the last new features that nano will have + before 2.0: copying text into the cutbuffer without + cutting it, indenting lines of marked text with a single + keystroke, reworked help text that should be easier for + new users, searching for filenames in the file browser, + the ability to include color regexes in files separate + from nanorc files, etc. It also contains many bugfixes. + Text can now be unjustified after justifying it and + resizing the window; the screen is now cleared when + suspending; the "default" color syntax is now handled + properly at all times; lines of text containing tabs are + now wrapped at the right place; double-column characters + are now properly displayed when past the right edge of + the screen; invalid multiline color regexes are now + ignored; and so on. Enjoy. + +2006.03.30 - GNU nano 1.3.11 awakens from its fever dream. This release + focuses mostly on bugfixes, which include better + handling of the cursor at the statusbar prompt, support + for certain combinations of Shift and keypad keys in + both normal and --rebindkeypad mode, a fix for a minor + display problem after some searches, a real fix for a + long-standing segfault when displaying overly long + lines, and a real fix for nano's not hanging up properly + in xterm under certain circumstances. There are also + several new features, such as the ability to set the + characters used as brackets when searching for matching + brackets, and tab completion of directories at the "Go + To Directory" prompt. Have fun. + +2005.12.23 - GNU nano 1.3.10 rises to the surface. This release + contains several new features as well as fixes for + several long-standing bugs. The former include the + ability to scroll up or down single lines without + scrolling the cursor, reworked bracket searching code + that doesn't require regular expression support, + reworked command execution code that uses $SHELL if + available instead of hardcoding "/bin/sh", and the + ability to no longer add newlines to files that don't + end in them via the -L/--nonewlines option. The latter + include fixes to the statusbar prompt so that mouse + clicks work properly on it, fixes to the Yes/No/All + prompt so that mouse clicks on it work properly when + -O/--morespace is used, and fixes to the resize handling + so that nano dies properly when the terminal is too + small to display a prompt. Enjoy. + +2005.10.23 - GNU nano 1.3.9 breaks through the wall. This release + includes major enhancements as well as bugfixes. The + enhancements include better handling of invalid UTF-8, + expansion of the word count option to also count lines + and characters in the file or selection, more efficient + screen update routines, a readded -K/--rebindkeypad + option to work around numeric keypad problems on + terminals that don't show the usual NumLock glitch, a + new -W/--wordbounds option to properly detect words + containing punctuation when moving among them, and + massive improvements to the color code such as handling + of unspecified foreground colors, more efficient memory + usage for color regexes, and new reserved syntaxes + "default" and "none". The bugfixes include fixes for + the rewritten history code, fixes for potential line + numbering problems on 64-bit platforms, fixes for a few + long-standing minor display problems, a fix for erroneous + hangups occurring while waiting for input, and a fix for + a segfault when displaying certain overly long lines. + Have fun with it. + +2005.06.30 - GNU nano 1.3.8 floats at its own level. This release + contains several new features. Among other things, + you can now move to a specified column number as well + as line number within a file, file backups saved in a + backup directory will have unique names, the search and + replace history routines should work more consistently, + you can get a word count by pressing Meta-D at the edit + window, and there's a new -E/--tabstospaces option to + convert all typed tabs to spaces (--backupdir's short + option has been changed to -C). In terms of bugfixes, + this release contains fixes for minor problems with + screen updates, UTF-8 display, and flow control; a fix + for a segfault when displaying some lines ending with + tabs; better handling of constant cursor position + display; improved color parsing in the rcfile; + and support for the "Regexp" toggle in tiny mode + (-R/--regexp is gone, and --restricted's short option + has been changed to -R), among other things. Enjoy. + +2005.04.10 - GNU nano 1.3.7 claws its way to the top. This release + mostly contains bugfixes for the massive amount of new + code in 1.3.6. Among other things, nano builds with + debug support again; going into the help browser at the + "Read File" prompt no longer kicks you out of the prompt + after you exit the help browser; paragraph searching no + longer skips over certain cases of single-line + paragraphs; the titlebar no longer cuts off some UTF-8 + strings prematurely; and the text displayed in the help + browser is now wrapped as it was in nano 1.2.x, taking + UTF-8 support into account. New features include an + --enable/disable-utf8 configure option to explicitly + turn detection of UTF-8 support on or off, and sample + regexes for C++ as well as C. Have fun. + +2005.03.20 - GNU nano 1.3.6 "shout it from the rooftops" is released. + This release finally includes the long-awaited support + for UTF-8. Other new features include the ability to + insert UTF-8 characters using verbatim input; the + ability to delete all text from the cursor position to + the end of the file via ^W^X as (patched) Pico does; + improvements to input and output so that pasted text + displays faster, improvements to the statusbar prompt so + that more edit window shortcuts, including verbatim + input and previous/next word search, work in it; a new + option to allow using the formerly always-blank second + line of the screen as part of the edit window; and the + ability to refresh the help browser and file browser + windows via Ctrl-L. Notable bug fixes include a fix for + a segfault when using full justify, and a fix for the + long-standing bug where nano would keep running if the + terminal it was in died unexpectedly. Enjoy. + +2004.11.22 - GNU nano 1.3.5 hurls itself forward. New features in this + release include the ability to replace only marked text + when the mark is on, improvements to smooth scrolling so + that it applies everywhere instead of just affecting the + movement keys, improvements to how files are opened so + that they are no longer displayed unnecessarily, support + for multiple +LINE arguments in addition to multiple + filenames on the command line, autodetection of the + format to save a file in based on the format it was in + when it was opened, the ability to toggle both ways + between the "Read File" and "Execute Command" prompts + and the "Search" and "Go to Line" prompts, and support + for cross-compiling nano. As for bug fixes, the + "tabsize" nanorc option works again, mouse clicks on the + shortcut list trigger the right shortcuts again, + tab-completing a filename with %'s in it no longer + causes a segfault, the internal spell checker no longer + skips words after the cursor position when the cursor is + in the middle of the file, and spell checking of only + marked text now works properly. Have fun with it. + +2004.08.17 - GNU nano 1.3.4 marches forth after a false start. This + release mainly features fixes for the bugs that crept + into the last release. Among other things, nano now + compiles again with certain options, quoted justify now + works properly on systems without regex.h, full justify + no longer segfaults when used on a file with no + paragraphs, previous paragraph searching works properly + again, tab completion is properly disabled when needed + in restricted mode, Ctrl-C is no longer disabled after + using the alternate spell checker, the permissions of a + newly created file now match those of nano 1.2.x again, + and replacing all text in a file now properly updates + the screen in all cases. New features include sample + regexes for patch files, improvements to the sample + regexes for C files, and support for strings greater + than 1023 characters and/or containing nulls in + .nano_history. Additionally, the full justify keystroke + has been changed to match current Pico, and whitespace + display mode is now turned off by default. Enjoy. + +2004.06.28 - GNU nano 1.3.3 marches forth. There are several new + features in this release, including a restricted mode + that provides better security than just setting an + operating directory, the ability to justify the entire + file at once, support for a "smart" Home key that can + leap from the beginning of text on a line to the true + beginning of the line (or the reverse) in one stroke, + support for specifying an alternative spell checker in + $SPELL, the ability to specify the characters used to + display spaces and tabs so that they can easily be told + apart, and the ability to specify the characters marking + the ends of sentences as used in justification. There + are also several bug fixes; among other things, + justification now keeps spaces at the ends of all but + the last line of a paragraph as Pico does, saving a + marked selection no longer changes the current filename + to the filename the selection was saved under, resizing + now works better and no longer corrupts the screen under + slang, and the movement functions now avoid doing + unnecessary redraws and hence work faster. In short, + there are a lot of new things to play with. Enjoy. + +2004.03.31 - GNU nano 1.3.2 is prepared for the void. New features in + this release include the ability to spell-check only + marked text and the ability to save all backup files in + a specified directory instead of wherever the original + files are. Bug fixes include a fix for a segfault when + replacing certain regular expressions, fixes for some + misbehavior when doing searches, minor fixes to verbatim + input mode and keyboard input in general, better + handling of window resizes at certain times, and + allowing the mark to be saved properly again when + switching between multiple file buffers. nano has also + been ported to the Tandem NonStop Kernel. Have fun. + +2004.01.09 - GNU nano 1.3.1 is outside the gates. This release + features, among other things, fixes for the input + routines to deal with some problems they had, a + reorganized shortcut list for the help browser, minor + Pico compatibility improvements for the file browser, + fixes for misbehavior when replacing certain regular + expressions, and the ability to highlight those regular + expressions properly. It also allows searching without + prompting to work in view mode, adds support for glib + 2.x for those systems that need it, updates the .spec + file for the 1.3 branch, prompts you first when you try + to save a file under a different name, and adds a new + verbatim input mode that acts as ^V does under vi, but + with additional Pico compatibility (explained in the + FAQ). Basically, a bunch of fixes and a few new + features for your editor of choice. Enjoy. + +2003.10.22 - GNU nano 1.3.0 is loosed upon the world. This is the first + release in the unstable 1.3.x series, and as such it + includes a lot of new features, including the addition + of a -d option for those FreeBSD users with Backspace + keys that act like Delete keys, the ability to repeat + the last search without prompting, the ability to search + for the beginning or end of a paragraph, new smooth + paging routines to go with the smooth scrolling + routines, and various improvements to the input and + display routines to make them behave more intuitively. + It also includes the usual load of bugfixes. Enjoy. + + +2003.08.11 - GNU nano 1.2.2 is released, only four months since the + last version :-). This release includes fixes for + broken regex detection, search history recall, and + keypad handling with -K. Debugging strings are no + longer translated and comments denote where translations + should be as short as possible (i.e. the statusbar). + There are new examples for syntax highlighting, and + documentation updates and fixes. The 1.3.0 CVS tree + will be opening soon for all your nano desires, so stay + tuned! + +2003.04.19 - Happy Easter! GNU nano 1.2.1 is released. This release + features a new check for broken regexec() + implementations and some variable, function and macro + cleanups. Fixes are included for search history, + cutting marked text, alt keyboard mode, and the usual + translation and documentation updates. + +2003.02.19 - GNU nano 1.2.0 is released. Few changes from pre3, just + some doc and translation updates, and bugfixes for + justify and file conversion. For those of you who + haven't kept up with the 1.1 unstable series, v1.2 + brings nanorc support, color syntax highlighting, + multiple file buffers, search/replace history and much + much more. Please read the UPGRADE file for details, + and enjoy GNU nano 1.2.0. + + +2003.02.13 - GNU nano 1.1.99pre3 "The last testing version, no really!" + is released. This release includes fixes for wrapping + (again), resizing, color syntax highlighting, rcfile + parsing, the mouse code, more memory leaks, and some + reversion of the code to get the user's home directory + (nano will now again rely on $HOME). There are also + translation updates, a new manual page for the nanorc + file, and an UPGRADE file detailing the changes since + version 1.0. Please submit reports for any bugs you + might find to the development team (nano-devel@gnu.org), + and enjoy nano almost-1.2.0 ;-) + +2003.02.03 - GNU nano 1.1.99pre2 "bugs in my pockets, bugs in my shoes" + is released. There are, not surprisingly, only bugfixes + in this release as we move toward the stable 1.2.0 + release. Fixes are included for translatable string + format, subexpression replacement, constant cursor + position, invalid search regexes, justify, screen state on + SIGHUP and SIGTERM, cutting to end cuts with long lines, + many file browser and operating directory bugs, memory and + file descriptor leaks, marker code, spell checker, the + mouse code with long lines, multiple buffers and non-file + open errors, replacement string length, and a silly but + serious history message crash. There is also a drastic + improvement in CPU utilization for the color regex code. + Depending on the number of bugs found in this release, + there may be a 1.1.99pre3 or RC1, or just a 1.2.0 release. + Most of the major bugs seem to have been worked out, so if + you are waiting for a good time to test nano before the + official 1.2.0 release, this would be the one to use. + Happy bug hunting! + +2003.01.17 - GNU nano 1.1.99pre1 "enough already" has been released. + This release is, barring bug fixes and documentation + updates, what version 1.2.0 has looked like, feature + wise. There will very likely be bugs, just due the + volume of changes made in this release. Search and + replace string history has been added, including an + option to log history to ~/.nano_history (-H, + --historylog). Because of this, the Pico incompatible + search/replace string behavior that used to be the + default has been deleted. The old "pico" flag (-p) is + now compatible with Pico's "preserve" mode for allowing + flow control characters; by default this version ignores + both ^Q and ^S. The --disable-wrapping-as-root + configure option has been forward ported from version + 1.0.x, and a new flag to enable all extra options + (--enable-all) has been added. The internal spell + checker has been improved, meaning you will now be + prompted only once for each unique capitalization of a + given word. + There have also been lots of bug fixes, + including the "trying to insert a directory name in + multibuffer mode bug", the ugly spell checker scrolling, + the color code, cutting text crashes, justification, + deleting the "magic line" via replace, and cursor + positioning on the statusbar. There have also been the + usual helping of translation and documentation updates. + Please send all new feedback on this release + direct to the development list (nano-devel@gnu.org). + +2002.10.24 - GNU nano 1.1.12 "Make Jordi happy" is released. This + release demonstrates that nano is starting to freeze for + version 1.2. New features include a Meta-Y toggle for + syntax highlighting, pluralized i18n, and a handler for + SIGTERM. Nano now ignores XOFF (^S) to stop accidental + lock-ups, and no longer references malloc.h. + Also included are fixes for zero-length regex + matches, segfaults with --disable-mouse, justification, + memory corruption with the browser, version and help + cmdline output, and translation updates. Aside from the + (currently up in the air) search history behavior, the + next version of nano should be 1.1.99pre1. Have fun! + +2002.10.01 - GNU nano 1.1.11 "Oddball" is released. This release + features a new version of gettext, a new and improved + syntax highlighting engine, and some updates for the + nanorc.sample file. The toggles for case sensitivity + (Meta-C) and regular expressions (Meta-R) have changed + in the search and replace prompts, multibuffer status is + now displayed and can be toggled from the insert file + menu, and some wrapping behavior that changed in 1.1.10 + has reverted. The --enable-color warning was also made + less severe, as the color syntax code has improved, and + nano now uses extended regexes in the .nanorc file. + Also included are fixes for various memory + leaks, the operating directory option, username tab + completion, the page_up and down arrow, go to previous + word and next word, nanorc parser and line wrapping + code. Have fun! + +2002.07.25 - At long last! GNU nano 1.1.10 "What didn't we break?" + is released. This version of GNU nano features version + 0.11.2 of gettext, building with automake 1.6, some new + code for displaying control characters, browser + improvements, a new backup file option (-B, --backup), + a new option to ignore rc files (-I, --ignorercfiles), + compatibility with -pedantic, handling null characters + before EOF, a slightly sportier nanorc.sample and more. + Fixes are included for justification, the reading + and writing file routines, resizing and fill length, + millions of memory leaks, the usage screen was updated, + and the --quotestr and --regexp really work now ;-) + Enjoy :) + +2002.05.12 - GNU nano 1.1.9 is released, happy Mother's Day! This + release includes many new features, including a prepend + mode (^O,M-P), a new "syntax" command in the .nanorc to + allow multiple syntax highlighting types, and a new -Y, + --syntax flag to set a specific one if there's no + filename regex to match it against (i.e. w/mutt). The + ^space and M-space keys will now show up in the help + menu, which itself has been tweaked a bit, and many more + configure options should now cooperate (like the odd + pairing of --enable-tiny and --enable-multibuffer). The + marker should now work when using multiple buffers, and + the huge memory leak in color syntax highlighting has + been fixed. A lot of new stuff for everyone's favorite + text editor ;) Have fun! + +2002.03.30 - GNU nano 1.1.8 is released. New features include an + "Insert Output of External Command", ^R^X, and a .spec + file is now included in the distribution. There are + cleanups in the usage code, fixes for regex parsing, the + file browser, the NO_CONVERT auto-detect, indented + justification, the internal spell checker, and a serious + bug where reading a file of 0 lines would hang nano. + Also, the "show position" code now shows the starting + column as 1 instead of 0. Have fun! + +2002.03.05 - GNU nano 1.1.7 "let's change everything and see what breaks" + is released. New features include the new flags + -N, --noconvert (to stop any file format conversion) and + -Q, --quotestr (for the new quoted text justification), + a new tempnam() implementation to avoid silly warnings, + DOS and Mac file options in the Write File dialog, + multiple save files (file.1) for abnormal exits, + ^C now showing column as well as character position, and + multibuffer allowing duplicate files, even unnamed ones. + Also, the static shortcut and toggle lengths are history, + nano now reads SYSCONFDIR/nanorc if rc file support is + enabled, and nano is now built with (and for rebuilding + requires) autoconf 2.5. + This release also includes fixes for some memory + leaks, detecting DOS and Mac file format, justification, + suspending keys, search & replace under various + conditions, variable width for shortcuts, and the usual + ton of translation updates. + +2002.01.25 - GNU nano 1.1.6 is released. Lots of new features in this + release. New Meta-keys were added as alternates for + control sequences: Meta-A for the marker key (^^), and + Meta-G for the 'goto dir' key in the file browser (^_). + The color syntax highlighting now supports multiple + lines via start="regex" end="regex" syntax, and the + .nanorc regex format itself has changed. Also, the + gettext code was upgraded to version 0.10.40, and nano + will now display a message if only occurrence of a given + search exists. + For bugfixes, there are fixes for spelling, + stray newlines in the usage() function, suspend issues + with tcsh, auto-indent and wrapping clashes, ugly code + in rcfile.c, global variable compatibility with AIX. + There are also oodles of translation updates. Have fun + with it. + +2002.01.05 - GNU nano 1.1.5 is out. The main new feature in this + release is the changed behavior of the keypad. Nano + now does the Right Thing and uses keypad() by default. + If you wish to use the keypad arrow keys in certain + terminals, you may use the -K or --keypad flag to get + the old behavior. Users of other OSes should see better + handling of their non-keypad keys in this release. + Other changes include more Hurd fixes, fixes parsing the + .nanorc, display fixes for the color syntax highlighting, + gettext stabilization and many translation updates. + This is almost like a stable release, much like in the + 0.9.x series when every other release was the most stable + one :) Have fun! + +2001.12.11 - GNU nano 1.1.4 is released. This release contains + rudimentary color syntax support (but it's still + broken), compatibility fixes for the Hurd and FreeBSD, + spell checker and wrapping fixes, and more. It seems + that the amount of interest in the code is inversely + proportional to the amount of time since last release, + so it's time to show the world all the changes since + 1.1.3 ;) Have fun with it! + +2001.10.26 - GNU nano 1.1.3 is released. As far as new features go, + the help system is now available for all functions in + the editor. Also, nano will now also print a message on + the status bar when it automatically converts a file + from Mac or DOS format, and trying to load a file that + has already been loaded in multibuffer mode will now + also cause an error message. There is now a "goto + previous word" which you can use by hitting Meta-Space + Bar. + As for fixes, a SEVERE bug in the null_at code + which discarded the memory address of reallocated memory + has been fixed. This is probably the biggest bug fix in + well over the last year of development. There are also + some display fixes for when the screen shouldn't center + itself on cut or uncut text. Also, the comments in the + header files incorrectly said that nano was distributed + under version 1 of the GPL when the accompanying license + was the GPLv2. + If you're using nano-1.1, it is highly + recommended you upgrade to this release. If using 1.0, + wait for version 1.0.6 which should be available early + next week. Enjoy! + +2001.10.03 - GNU nano 1.1.2 is out there. Many new features in this + release, including support for auto-converting from DOS + and Mac formatted files, as well as toggles for writing + out files in these formats. Pico's -o flag has been + implemented, as has some new smooth scrolling code + (which can be used in place of the default jerky + scrolling behavior). Also, there is now a "find + matching bracket/brace/etc" feature (Meta-]). The + .nanorc file now accepts setting the tabsize, and the + help text at the bottom of the editor is now better + spaced out in the search/replace prompts. There are + also the usual helping of bugfixes, translation updates + and, surely a bug or two. You better get ready! + +2001.07.28 - GNU nano 1.1.1 is released. Our second 1.1 unstable + release features many bugfixes from the initial release, + in particular fixes for the multibuffer code, and + various compiler macro fixes. The shortcut lists for + the search and replace prompts are a little more logical + (with cancel the last option again), and the included + gettext was re-downgraded to 0.10.35 due to problems on + the PPC platform. GNU nano now includes its own aclocal + macros in the m4/ directory to allow rebuilding the + configure script to work on platforms regardless of + their gettext version. + +2001.07.15 - GNU nano 1.1.0 is released. This is the first release + in the 1.1.x unstable series of GNU nano. It + incorporates all changes up to the 1.0.3 release, and + also includes many many new features, including + appending to as well as overwriting files, writing + marked text to a separate file, dynamic wrap length, + lots more compatibility with Pico, and new optional + features like .nanorc file support and multiple file + buffers! All in all, plenty of new stuff that's sure to + introduce lots of bugs ;-) Have fun with it, but be + careful, unstable means unstable. + + +2001.07.01 - GNU nano 1.0.3 is the "mutt" release. This release + features oodles of bug fixes with cutting text, + especially with the -k (cut to end) option. There is + also a new suspend handler which should make nano play + better with mutt (the code for which came from mutt + itself; many many thanks to Jordi Mallach and Tom Lear + for working late into the night fixing this). Nano now + also features mutt's case insensitive string compare + function for more speed and less memory usage. Two new + translations are included, Ukrainian and Russian. + +2001.05.12 - GNU nano 1.0.2 is the "just the bugfixes ma'am" release. + The most noticeable fixes are for display errors using + page up/down with the marker code, and view mode (-v) + not stopping the replace function. Other fixes include + being able to use the arrow keys while holding down the + ctrl key in certain TERMs, and there are many + documentation updates and spelling tweaks. We also have + a new Galician translation (provided by Jacobo Tarrío). + Have fun with it! + +2001.04.06 - GNU nano 1.0.1 is out there. The only new feature is a + configure option for those who want to disable all word + wrapping from nano, --disable-wrapping. Bug fixes this + release include some bugs with autoconf and i18n, and + several fixes in the file browser including a segfault + on Solaris, symlinks to directories now work properly, + and nano now sorts files case insensitively like Pilot. + Have fun with it. + +2001.03.22 - GNU Nano 1.0 is released! The autoindent wrapping bug + has been fixed, as well as a strange bug when using Pico + mode and regex search. There have also been some minor + spelling and documentation updates. As stated on the + website, there are currently no known bugs with nano, + but some will pop up eventually and they will be + addressed in subsequent releases. We hope you enjoy + this first stable release of nano, and as always, + feedback is welcome! + + +2001.02.19 - Nano 0.9.99pre3 brings a lot of changes! The most important + being that nano is now officially a GNU program. Some + changes have been made for GNU compatibility (like in the + default list of shortcuts: "^G Get Help" is now listed + and "^_ Goto Line" is not). The Yes/No/All keys have + finally been internationalized also. All in all, quite + a few changes, considering nano is supposed to be in + a code freeze. But there are the usual helping of + bugfixes, a nasty bug when cutting text in -k mode and + some compatibility issues with older ncurses libraries + have also been fixed. All in all, a lot to see. + +2001.01.31 - Nano 0.9.99pre2 is released. Not surprisingly, all that + is new is bugfixes, bugfixes, bugfixes. There were a + few cleanups in unneeded global variables and duplicate + functions, but most is just fixing. Specifically, there + is now a preliminary (read: needs testing) fix for + resizing the editor in any mode other than normal edit + mode. Other fixes include some more tab completion + segfaults, and a silly segfault that occurred when + successfully writing a file on the 2nd try (i.e. after + an initial write error). Slowly but surely, on toward + 1.0 we travel. + +2001.01.17 - Nano 0.9.99pre1 is released. This is the first pre-1.0 + release of nano, and is also the first release since the + code freeze for nano 1.0. Don't expect (or request) any + new features between now and nano 1.0, only bugfixes, + optimizations and doc/translation updates. For fixes, a + nasty segfault when trying to insert one's home directory + (~), some checks for the NumLock key making the keypad go + awry, window size sanity checks, many autoconf fixes, and + support for the KDE Konsole keypad layout. Have fun. + +2001.01.07 - Nano 0.9.25 is the "Just one more feature I swear!" + release. It includes one new feature that Pico has had + forever, a built-in file browser. Since not everyone + may want this option, there is a --disable-browser + option to the configure script as well. Other changes + include slightly different keypad handling, and a bugfix + for crashes when tab completion in certain instances. + Have fun and Happy New Year! + +2000.12.18 - Nano 0.9.24 is released. This version contains the last + of the security fixes for writing files, as well as for + a nasty segfault when nano is unable to open a file for + reading, among other fixes. Nano now also cowardly + refuses to open device files, to stop silly things like + trying to open /dev/zero. New features include being + able to use Meta-Meta- as Control-, better + HURD support, and some new flags have been added for + Pico compatibility. Upgrading to this version is highly + recommended. + +2000.12.08 - Nano 0.9.23 is the "race conditions bite" release. The + main reason for this release is the less-than-optimal + fix for the security issue in nano with following + symbolic links. Hopefully this will fix the problem + permanently. The --nofollow option also works again + for those who are real security nuts. There are also + some display and search fixes, and the --disable-spell + function was renamed to --disable-speller to be in line + with nano and Pico's "speller" term. + +2000.12.02 - Nano 0.9.22 is released, with many more changes and + additions than imaginable. The most important change is + a fix for unsafe handling of symbolic links which could + lead to symlink attacks if nano were to exit because of + an error or signal. Also there are better checks when + saving files. + As for new features, username tab completion is now + working well, the internal spell checker code has been + tweaked, you can now unjustify if you don't like how the + justify formatted your text, and there are more options + for configure, including --disable-spell and + --disable-justify and --enable-extra (for those who like + surprises). All in all, a whole lot of changes in a + little over a week. + +2000.11.23 - Happy Thanksgiving! Nano 0.9.21 is our "last version was + a big turkey" release. It fixes several bugs introduced + by the previous version, as well as a few long-standing + display bugs. All 0.9.20 users are strongly encouraged + to upgrade to this release. + +2000.11.18 - Nano 0.9.20 is finally out the door. Probably the biggest + change is the brand new way nano displays previous search + and replace strings (they are now editable!) This is a + break from Pico's (inconsistent) interface, so if you + don't like the new way, "Pico" mode (-p on the command + line or Meta-P within nano) still works the "old" way. + Other new features include being able to deal with + search strings of any length, a new internal spell feature + (courtesy of Mr. Rocco Corsi) and tab completion when + reading in or writing out files! There's also the usual + billion or so bug fixes. Feedback on this release is + welcome because so much has changed, especially with the + previous string display in search and replace. Email + -> nano@nano-editor.org <-. If you like something, + don't like something, or just want to order a pizza, + let us know! + +2000.10.02 - Nano 0.9.19 is the "Chris is getting married in less than + a week and needs a distraction" release. There are only + a few actual code changes, mainly portability and + compiler warning fixes. Nano now also supports + PDCurses, which enables easily-built nano executables + for Windows NT and 95/98 for the brave. The official + nano site has changed (again) as well, check out + www.nano-editor.org for all the latest nano schtuff. + +2000.09.18 - Nano 0.9.18 is unleashed. It has some new keyboard + handling code, Cygwin support out of the box, and a more + portable handler for the NOHELP toggle. There is also a + fix for a somewhat serious bug whereby trying to insert + a directory instead of a normal file would destroy the + contents of the editor. A must-see. Four stars. + +2000.09.04 - Nano 0.9.17, the Labor Day release, is released after a + quiet spell (almost an entire month since last release!) + New features include better (not yet perfect) binary + display support and toggle support for most of the + program flags (M-c, M-i, M-z, M-x, M-p, M-w, M-m, M-k + and M-e for -c, -i, -z, -x, -p, -w, -m, -k, and -R). + +2000.08.09 - Nano 0.9.16, after some struggling, is released. This + release should fix a few of the holes that 0.9.15 dug. + The "cutting text on the first line" bug is fixed, as is + the "cutting text on the last line" bug. Nice symmetry + there huh? Also the --tabsize argument should now work + as well as by using -T. + +2000.08.03 - Nano 0.9.15 is the "I can't think of a release description" + release. There are the usual gala of display bugfixes, + a fix for the nasty bug in -k mode that could create + a loop in the file being edited, and some other code + cleanup. Also, the -T option should now work regardless + of the curses library used. Yay. + +2000.07.27 - Nano 0.9.14 is officially the "13 is so unlucky it should + be skipped as a version number" release. One typo caused + unending problems (calling nano with either -t or -k + caused both flags to be used). The -k code is now also + closer in functionality to Pico's -k mode; please note + that this code is not finished yet. Working on this code + has made me realize that there is not enough abstraction + in the code, and I will be working on that for the next + release. Until then, have fun with this version. + +2000.07.23 - Nano 0.9.13 has a few new bits and bobs, most notably the + -k option from Pico (cut to end of line). The majority + of changes in this release are bugfixes, however, + including the usual display fixes and fixes for writing + to symbolic links and unwritable files. Barring any + other major changes, this should be the feature set for + nano 1.0, whenever it might be released =-) + +2000.07.07 - Nano 0.9.12 (the "lucky day" release) is bursting with + new features, bug fixes, and yummy fruit flavor. For + changes, the alternate replace keystroke ^W^T is now + ^W^R to be compatible with later versions of Pico. ^W^T + is now goto line, again for Pico compatibility. As for + new features, the wonderful/hated magic line code has + returned with a vengeance! Also, regular expression + searches and replaces have been incorporated via the -R + flag. And, of course, there are the usual helping of + display and other bug fixes to top it all off. + +2000.06.20 - Nano 0.9.11 presents drastic rewrites of the most buggy + routines in the program, specifically the wrapping code + and almost all of the display routines. There are many + improvements and bugfixes to the display subsystem in + general, but there may be bugs lurking yet. Also, after + many MANY requests, there is now an option to set the + displayed tab width (-T, --tabsize). Note that this + function just changes the way tabs LOOK in the editor, + the tabs you input are still real tabs of normal width + (usually 8 characters); nano just makes them look + smaller or bigger while in the editor. New in the + translation department is an Indonesian translation + (id). + +2000.06.06 - Nano 0.9.10 is primarily a bugfix for the loss of SIGINT + when using "run and terminate" flags (for example, --help). + There are also some minor documentation updates. This + version of nano is the most stable in quite some time, + and is likely to be the most stable for awhile. Users + are encouraged to upgrade to this version. + +2000.05.31 - Nano 0.9.9 introduces much better working i18n support, + more portability, and a ton of bugfixes. While nano is + not likely anywhere near 1.0 in terms of code quality, + it gets a quantum leap closer with this release. + +2000.05.18 - Nano 0.9.8 (the 'what broke now?' release) should fix + the resize crash people have been experiencing. It also + offers a new input method that should allow nano to do + things the right way (like ^S, ^Q, custom suspend keys) + and hopefully won't break with non-US keyboards. There + are also the obligatory display fixes and speedups. + Have fun with it. + +2000.05.14 - Nano 0.9.7 (the Mother's Day release) continues in the + long line of display fixes, and also fixes the broken + symlink behavior (i.e. symlinks weren't being followed + by default). Hopefully all major bugs can be worked out + soon and we can have a 1.0 release before the end of the + year, but who knows. + +2000.05.08 - Nano 0.9.6 cleans up a lot of the display bugs that 0.9.5 + uncovered. There are improvements (and some remaining + segfaults) in the wrapping code, and even more display + optimizations. I would still say 0.9.4 or 0.9.2 are the + most stable versions of nano to date, but this one may + not be too bad =-) + +2000.05.01 - Nano 0.9.5 attempts to speed up the display of text to be + at least somewhat reasonable. Much code profiling has been + done to reduce the ridiculous number of redundant display + updates. This will probably expose a lot of bugs that can + then be fixed, so this release is probably not for the faint + of heart. For anyone curious, I would call nano 0.9.2 the + most stable version recently, so use that if you're not + particularly concerned with being on the bleeding edge. + +2000.04.25 - Nano 0.9.4 fixes some problems in 0.9.3 with the last + line code and related segfaults. It now also has much + better handling for 8-bit characters. The --enable-tiny + code also produces a smaller executable. + +2000.04.19 - Nano 0.9.3 is officially the "Micro$oft" release. It + underscores the recent problem of bugfixes introducing + more bugs than they fix. The most important change to + this version of nano is the removal of the "magic line". + You will no longer see a blank line at the end of the + file. If you want a new line at the end of your file, + you'll have to hit enter to get one. + + NOTE: THIS BREAKS COMPATIBILITY WITH PICO. + Unfortunately, this feature has been causing many many + problems with nano so it is being removed for the time + being, and perhaps indefinitely. + + Other new stuff includes an --enable-tiny option to make + nano ultra small (disabling i18n, detailed help and the + marker and mouse code), and --with-slang to use the + slang libraries instead of ncurses. + +2000.04.15 - Nano 0.9.2 just fixes the serious segfault problem if + nano is invoked any way other than using the absolute + path. The bug was in the new code for checking whether + nano is invoked as 'pico'. + +2000.04.14 - Nano 0.9.1 has some more Pico compatibility built-in. The + option to switch to/from Search and Search/Replace (^T) + is now available, and nano now displays the more + Pico-like shortcut list when invoked as 'pico' (i.e. if + 'pico' is a symlink to nano). There is an important + change to the handling of symbolic links as well. Now, + nano does the "correct" thing and automatically writes + to the object of the symlink, rather than replace the + symlink with the updated file. This behavior is still + available with the --nofollow or -l flags. + Other new things include a fix for the infamous + "recursive replace" bug, and more bugfixes in the + wrapping code. + +2000.04.07 - Nano 0.9.0 has some updates, new language support and + a much better refresh setup (It's still not great, + but...) There should also be more stability editing + long lines, as there was a stupid mistake in the + update_line call. Silly me =) + +2000.03.22 - Nano 0.8.9 is basically just a bugfix release of 0.8.8 + to reflect the current stagnant status of the project. + Most things work, the rest doesn't doesn't work because + (a) I can't fix it or I would have already done so, and + (b) the amount of patches I'm receiving right now is + quite negligible. Fortunately, this release marks the + first release since I have acquired ownership of the + nano pages on SourceForge. Here's hoping SF will get us + some more visibility, translators and patches. + +2000.03.12 - After a hiatus, I have finally moved (not unpacked though) + to my new home into Albany. Thus I should now have more + time to work on nano. Nano 0.8.8, the "dear god what + broke this time?" release, incorporates patches for both + i18n and many bugfixes. It is VERY likely something + broke this version, and it's likely I didn't even apply + the i18n stuff properly, so *it* may not even work. + + I would like to announce that I'm going to need + translations soonish, so if you are fluent in other + languages than English (or even better, if your native + language is not English) and you would like to submit a + translation file to me, please feel free to do so. If + you do, I will list your name and email in the AUTHORS + file as the maintainer of the .po file, and from then on + it is yours to take care of and keep up to date. + +2000.03.01 - Well, to continue my trend of going back on my previous + release's comments, nano 0.8.7 is released. The crashing + behavior was still occurring, and this most recent fix + also fixes some other wrapping problems, so here you go. + There may be another release soon, there may not be, is + that vague enough? =) + +2000.02.25 - More minor bugfixes in 0.8.6, the bizarre behavior at the + end of a page has ceased, thankfully. I'm also moving + next weekend, so don't be shocked if you don't see a new + version of nano next week =-) + +2000.02.11 - Okay, here we go again. Aside from a few minor fixes + and some under-the-hood changes, you won't notice much + different in this version of nano. I haven't gotten + much feedback on the help feature, is it simply amazing + or does no one care? Write and let me know! =) + +2000.02.08 - Nano 0.8.3 marks the first time in a long time that there + has been more than three days since the last release. + New features include an initial help mode (YAY!), + hopefully much more support for i18n out of the box, and + a flag for more Pico compatibility in the shortcut lists + displayed. This release also marks the new nano + distribution site, http://www.asty.org/nano and email + address nano@asty.org for bugs, etc. + +2000.02.02 - Okay, I hate to go back on what I said in the last release, + but I may be changing jobs very soon. I will release version + 0.8.2 as is (no i18n, no help menu (yet)). I expect things + to settle down by the end of next week, and then I can try to + start on the i18n support and help menu; look for these new + features in version 0.8.5 to 0.9.0. + +2000.01.28 - Nano 0.8.1 marks our first official step toward + internationalization (i18n) and the help system (^G). + I will be merging in Jordi's patches for initial i18n + in the next version, and will implement the help system + with i18n built into it shortly after that. Please + don't hesitate to send bug reports, as long as you're + sure the fault lies with nano =-). + +2000.01.25 - Nano 0.8.0 is officially the "let's try and be at least + a little portable, mmmmkay?" release. There are many + portability checks and fixes; many thanks to Andy Kahn + for his patches. I removed the broken do_spell behavior + with the 'spell' program; for now, we only try to call + 'ispell' until I write a better method to handle the + output of the normal 'spell' command. + +2000.01.24 - Nano 0.7.9 features many new features. Among them are a + new autoindent feature (-i, --autoindent), tempfile flag + like Pico's -t flag (-t, --tempfile), and preliminary + spelling program support. The spelling function tries to + run 'spell' and then 'ispell' in that order, but you can + specify another spelling program with -s or --speller. + +2000.01.17 - Nano 0.7.7 is officially the "way too much stuff changed + this release" release. It's the busy time at work for me, + so please don't get offended if your patch doesn't get + included in the next immediate version of nano. I'm sure + all the changes in this release will cause a few bugs, so + 0.7.8 will primarily be about fixing those bugs. + + Things added this release include resizability (kinda), + new -x and -c flags (see nano -h for help), long command + line flag support, and the usual array of bugfixes. + +2000.01.15 - Nano 0.7.6 is officially the "lightning" release. + It now loads large files much faster than previous + versions, and is even much faster than Pico or vi + in some rather rudimentary tests. Many thanks to + Adam Rogoyski for the read_byte patch! + +2000.01.09 - As of this version (0.7.4), TIP has officially + been renamed to nano. The new homepage is at + http://faculty.plattsburgh.edu/astyanax/nano. + Please update your bookmarks, tell your friends, + and all that jazz. diff --git a/README b/README new file mode 100644 index 0000000..b746045 --- /dev/null +++ b/README @@ -0,0 +1,122 @@ + + GNU nano -- a simple editor, inspired by Pico + +Purpose + + Nano is a small and simple text editor for use on the terminal. + It copied the interface and key bindings of the Pico editor but + added several missing features: undo/redo, syntax highlighting, + line numbers, softwrapping, multiple buffers, selecting text by + holding Shift, search-and-replace with regular expressions, and + several other conveniences. + +Appearance + + In rough ASCII graphics, this is what nano's screen looks like: + + ____________________________________________________________________ + | GNU nano 7.2 filename Modified | + -------------------------------------------------------------------- + | This is the text window, displaying the contents of a 'buffer', | + | the contents of the file you are editing. | + | | + | The top row of the screen is the 'title bar'; it shows nano's | + | version, the name of the file, and whether you modified it. | + | The two bottom rows display the most important shortcuts; in | + | those lines ^ means Ctrl.

1. General

+

1.1. What is GNU nano?

+

GNU nano was designed to be a free replacement for the Pico text editor, part of the Pine email suite from The University of Washington. It aimed to "emulate Pico as closely as is reasonable and then include extra functionality".

+

1.2. What is the history behind nano?

+

Funny you should ask!

+

In the beginning...

+

For years Pine was THE program used to read email on a Unix system. The Pico text editor is the portion of the program one would use to compose his or her mail messages. Many beginners to Unix flocked to Pico and Pine because of their well organized, easy to use interfaces. With the proliferation of GNU/Linux in the mid to late 90's, many University students became intimately familiar with the strengths (and weaknesses) of Pine and Pico.

+

Then came Debian...

+

The Debian GNU/Linux distribution, known for its strict standards in distributing truly "free" software (i.e. software with no restrictions on redistribution), would not include a binary package for Pine or Pico. Many people had a serious dilemma: they loved these programs, but the versions available at the time were not truly free software in the GNU sense of the word.

+

The event...

+

It was in late 1999 when Chris Allegretta (our hero) was yet again complaining to himself about the less-than-perfect license Pico was distributed under, the 1000 makefiles that came with it and how just a few small improvements could make it the Best Editor in the World (TM). Having been a convert from Slackware to Debian, he missed having a simple binary package that included Pine and Pico, and had grown tired of downloading them himself.

+

Finally something snapped inside and Chris coded and hacked like a madman for many hours straight one weekend to make a (barely usable) Pico clone, at the time called TIP (Tip Isn't Pico). The program could not be invoked without a filename, could not save files, had no help text display, spell checker, and so forth. But over time it improved, and with the help of a few great coders it matured to the (hopefully) stable state it is in today.

+

In February 2001, nano was declared an official GNU program by Richard Stallman. nano also reached its first production release on March 22, 2001.

+

1.3. Why the name change from TIP?

+

On January 10, 2000, TIP was officially renamed to nano because of a namespace conflict with another program called 'tip'. The original 'tip' program "establishes a full duplex terminal connection to a remote host", and was included with many older Unix systems (and newer ones like Solaris). The conflict was not noticed at first because there is no 'tip' utility included with most GNU/Linux distributions (where nano was developed).

+

1.4. What is the current version of nano?

+

The current version of nano should be 7.2. Of course, you should always check the nano homepage to see what the latest and greatest version is.

+

1.5. I want to read the man page without having to download the program!

+

Jeez, demanding, aren't we? Okay, look here.

+
+ +

2. Where to get GNU nano.

+

2.1. Web sites that carry nano.

+

The nano source tarballs can be downloaded from the following web sites:

+ +
+

2.2. RPM packages (RedHat, OpenSuse, and derivatives).

+
+ +
+

2.3. Deb packages (Debian and derivatives):

+

Debian users can check out the current nano packages for:

+ +

You can also have a look at the Package Pool to see all the available binary and source packages.

+
+

2.4. By git (for the brave).

+

For the "bleeding edge" current version of nano, you can use git to download the current source code. Note: believe it or not, by downloading code that has not yet stabilized into an official release, there could quite possibly be bugs, in fact the code may not even compile! Anyway, see the hacking document for info on getting and building nano from git.

+
+ +

3. Installation and Configuration

+

3.1. How do I install the RPM or DEB package?

+

It's simple really! As root, type rpm -Uvh nano-x.y-1*.rpm if you have a RedHat-ish system or dpkg -i nano_x.y-1*.deb if you have a Debian-ish system, where x.y is the version number of nano. There are other programs to install packages, and if you wish to use those, knock yourself out.

+

3.2. Compiling from source: WHAT THE HECK DO I DO NOW?

+

Okay, take a deep breath, this really isn't hard. Unpack the nano source with a command like:

+

tar -xvf nano-x.y.tar.gz

+

Then you need to run configure with any options you might want (if any).

+

The average case is this:

+

cd nano-x.y/
+ ./configure
+ make
+ make install   #(as root, of course)

+

3.3. Why does everything go into /usr/local?

+

Well, that's what the configure script defaults to. If you wish to change this, simply do this:

+

./configure --prefix=/usr

+

This will put nano into /usr/bin when you run make install.

+

3.4. nano should automatically run strip on the binary when installing it!

+

It does when you use make install-strip. The default make install does not, and will not, run strip automatically.

+

3.5. How can I make the executable smaller? This is too bloated!

+

Actually, there are several parts of the editor that can be disabled. You can pass arguments to the configure script that disable certain features. Here's a brief list:

+ 
+    --disable-browser       Disable the built-in file browser
+    --disable-color         Disable color and syntax highlighting
+    --disable-comment       Disable the comment/uncomment function
+    --disable-extra         Disable the easter egg
+    --disable-formatter     Disable the formatting tool
+    --disable-help          Disable the built-in help texts
+    --disable-histories     Disable the saving of search strings and cursor positions
+    --disable-justify       Disable the justify/unjustify functions
+    --disable-libmagic      Disable the use of libmagic for determining a file's syntax
+    --disable-linenumbers   Disable line numbering
+    --disable-linter        Disable the linting tool
+    --disable-mouse         Disable mouse support
+    --disable-multibuffer   Disable the opening of multiple file buffers
+    --disable-nanorc        Disable the use of .nanorc files
+    --disable-operatingdir  Disable the setting of an operating directory
+    --disable-speller       Disable the spell-checking tool
+    --disable-tabcomp       Disable the tab-completion functions
+    --disable-wordcomp      Disable the word-completion function
+    --disable-wrapping      Disable all hard-wrapping of text
+

There's also the --enable-tiny option which disables everything above, as well as some larger chunks of the program (like the undo/redo code and the code for selecting text). Also, if you know you don't need other languages, you can use --disable-nls to disable internationalization and save a few kilobytes. And finally, there's always good old strip to remove all unneeded symbols.

+
+

3.6. Tell me more about this multibuffer stuff!

+

To use multiple file buffers, you must not have configured nano with --disable-multibuffer nor with --enable-tiny (use nano -V to check the compilation options). Then when you want to insert a file into its own buffer instead of into the current file, just hit Meta-F after typing ^R. If you always want files to be loaded into their own buffers, use the -F or --multibuffer flag when you invoke nano, or add set multibuffer to your .nanorc file.

+

You can move between the buffers you have open with the Meta-< and Meta-> keys, or more easily without holding Shift: Meta-, and Meta-. (clear as mud, right? =-). When you have more than one buffer open, the ^X shortcut will say "Close", instead of "Exit".

+

3.7. Tell me more about this verbatim input stuff!

+

When you want to insert a literal character into the file you're editing, such as a control character that nano usually treats as a command, first press Meta-V (if you're not at a prompt, you'll get the message "Verbatim Input" on the status bar), then press the key(s) that generate the character you want.

+

Alternatively, if Unicode support is enabled (see section 5.3), you can press Meta-V and then type a six-digit hexadecimal code (from 000000 to 10FFFF, case-insensitive), and the character with the corresponding value will be inserted. The status bar will change to "Unicode Input: ......" when you do this.

+

3.8. How do I make a .nanorc file that will be read when I start nano?

+

It's not hard at all! Simply copy the sample.nanorc from the doc/ directory in the nano source package (or from /usr/doc/nano on your system) to .nanorc in your home directory, and then edit it. If you didn't get a sample nanorc, the syntax of the file is simple: features are turned on and off by using the words set and unset followed by the long option name of the feature (see man nanorc for the full list of options). For example, "set quickblank" or "set smarthome". Of course, for this to work, your nano must not have been compiled with --disable-nanorc.

+

3.9. Why does my self-compiled nano not read /etc/nanorc?

+

By default (see 3.3), nano gets installed into /usr/local. This also means that, at startup, nano will read /usr/local/etc/nanorc instead of /etc/nanorc. You can make a symlink from the former to the latter if you want your self-compiled nano to read the same nanorc as the system-installed nano. Or you can configure your nano to overwrite the system nano (again, see 3.3).

+
+ +

4. Running

+

4.1. Alt+Up does nothing on a Linux console. How can I make it scroll?

+

On Debian and its derivatives, the Alt+Up keystroke on a Linux console + produces by default a 'KeyboardSignal', which normally does absolutely nothing and is useless + for the average user. To get the keystroke to do what it ought to do (scroll the viewport + one row up), run this in a Linux console:

+

dumpkeys --full | sed s/KeyboardSignal/Up/ | sudo loadkeys -

+

You will need to run this command whenever you first switch to a Linux console.

+

Or you can (as root) execute the following little script just once:

+

for file in /etc/console-setup/cached*.kmap.gz; do
+     gunzip $file;
+     sed -i 's/KeyboardSignal/Up/' ${file%.gz};
+     gzip ${file%.gz};
+ done

+

4.2. How can I make Ctrl+Shift+Left/Right select words on urxvt?

+

The urxvt terminal emulator produces non-standard escape sequences for the modified cursor keys. These deviant sequences are not listed in the terminfo database, which means that ncurses does not recognize them. The easiest way around this is to tell urxvt to produce xterm-compatible escape sequences for the relevant keystrokes. To achieve this, add the following lines to your ~/.Xresources file:

+
+    URxvt.iso14755_52: False
+
+    URxvt.keysym.C-S-Up: \033[1;6A
+    URxvt.keysym.C-S-Down: \033[1;6B
+    URxvt.keysym.C-S-Right: \033[1;6C
+    URxvt.keysym.C-S-Left: \033[1;6D
+
+    URxvt.keysym.M-Up: \033[1;3A
+    URxvt.keysym.M-Down: \033[1;3B
+    URxvt.keysym.M-Right: \033[1;3C
+    URxvt.keysym.M-Left: \033[1;3D
+
+    URxvt.keysym.M-Insert: \033[2;3~
+    URxvt.keysym.M-Delete: \033[3;3~
+
+    URxvt.keysym.M-Page_Up: \033[5;3~
+    URxvt.keysym.M-Page_Down: \033[6;3~
+

Then run xrdb ~/.Xresources and restart your urxvt terminal. Now Ctrl+Shift+Left and Ctrl+Shift+Right will select words, Alt+Up and Alt+Down will scroll the text without moving the cursor, and several such things more.

+

4.3. Ack! My numeric keypad's keys don't work properly when NumLock is off! What can I do?

+

You can use the -K or --rawsequences option on the command line, or add the line set rawsequences to your .nanorc. However, nano's mouse support will be disabled if you do any of these things.

+

4.4. With what keystroke can I paste text from the clipboard into nano?

+

In most desktop environments Shift+Insert will paste the contents of the clipboard.

+

4.5. How do I select text for or paste text from the clipboard when nano's mouse support is turned on?

+

Try holding down the Shift key and selecting or pasting the text as you normally would.

+

4.6. When I paste text into a document, each line gets indented further than the last. Why? And how can I stop this?

+

You have the autoindent feature turned on. Hit Meta-I to turn it off, paste your text, and then hit Meta-I again to turn it back on.

+

Update: Since version 4.8, nano will suppress auto-indentation during a paste, so you no longer need to toggle it off and on manually.

+

4.7. When I paste from Windows into a remote nano, nano rewraps the lines. What gives?

+

When pasting from Windows, in some situations linefeeds are sent instead of carriage returns (Enters). And linefeeds are ^Js, which make nano justify (rewrap) the current paragraph. To prevent these linefeeds from causing these unwanted justifications, add this line to your .nanorc on the remote Linux box: unbind ^J main or bind ^J enter main, depending on whether the paste contains CR + LF or only LF.

+

Update: Since version 4.8, nano will ignore linefeed characters in a paste, so you no longer need the above workaround.

+

4.8. I've compiled nano with color support, but I don't see any color when I run it!

+

If you want nano to actually use color, you have to specify the color configurations you want it to use in your .nanorc. Several example configurations are in the syntax/ subdirectory of the nano source, which are normally installed to /usr/local/share/nano/. To enable all of them, uncomment the line # include "/usr/local/share/nano/*.nanorc" in your nanorc. See also section 3.9.

+

4.9. How do I make nano my default editor (in Pine, mutt, etc.)?

+

You need to make nano your $EDITOR. If you want this to be saved, you should put a line like this in your .bashrc if you use bash (or .zshrc if you believe in zsh):

+

export EDITOR=/usr/local/bin/nano

+

or, if you use tcsh, put this in your .cshrc file:

+

setenv EDITOR /usr/local/bin/nano

+

Change /usr/local/bin/nano to wherever nano is installed on your system. Type "which nano" to find out. This will not take effect until the next time you log in. So log out and back in again.

+

Then, on top of that, if you use Pine, you must go into setup (type S at the main menu), and then configure (type C). Hit Enter on the lines that say:

+

[ ] enable-alternate-editor-cmd
+ [ ] enable-alternate-editor-implicitly

+

Then exit (E) and select Yes (Y).

+

If you're a mutt user, you should see an effect immediately the next time you log in. No further configuration is needed. However, if you want to let people know you use nano to compose your email messages, you can put a line like this in your .muttrc:

+

my_hdr X-Composer: nano-x.y

+

Again, replace x.y with the version of nano you use.

+
+ +

5. Internationalization

+

5.1. There's no translation for my language!

+

In June 2001, GNU nano entered the Translation Project and since then, translations should be managed from there.

+

If there isn't a translation for your language, you could ask your language team to translate nano, or better still, join that team and do it yourself. Joining a team is easy. You just need to ask the team leader to add you, and then send a translation disclaimer to the FSF (this is necessary as nano is an official GNU package, but it does not mean that you transfer the rights of your work to the FSF, it's just so the FSF can legally manage them).

+

In any case, translating nano is easy. Just grab the latest nano.pot file listed on nano's page at the TP, and translate each msgid line into your native language on the msgstr line. When you're done, you should send it to the TP's central PO-file repository.

+

5.2. I don't like the translation for <x> in my language. How can I fix it?

+

The best way is to send an e-mail with your suggested corrections to the team's mailing list. The address is mentioned in the Language-Team: field in the relevant PO file. The team leader or the assigned translator can then make the changes reach the nano-devel list.

+

5.3. What is the status of Unicode support?

+

Unicode should be fully usable nowadays. When the encoding of your terminal is set to UTF-8, and your locale (mainly the LANG environment variable) is UTF-8 too, then you should be able to read, enter and save Unicode text.

+
+ +

6. Advocacy and Licensing

+

6.1. Why should I use nano instead of Pico?

+

If you want features like undo/redo, syntax highlighting, line numbers, soft-wrapping, opening multiple files at once, an interface localized to your language, or search and replace with support for regular expressions, then you want nano.

+

6.2. Why should I use Pico instead of nano?

+

If you use your editor only to write emails or other texts and have no need for the above-mentioned features, then Pico will do fine for you.

+

6.3. What is so bad about the older Pine license?

+

The U of W license for older versions of Pine and Pico is not considered truly Free Software according to both the Free Software Foundation and the Debian Free Software Guidelines. The main problem regards the limitations on distributing derived works: according to UW, you can distribute their software, and you can modify it, but you can not do both, i.e. distribute modified binaries.

+

6.4. Okay, well, what mail program should I use then?

+

If you are looking to use a Free Software program similar to Pine, and Emacs is not your thing, you should definitely take a look at mutt. It is a full-screen, console based mail program that actually has a lot more flexibility than Pine, but has a keymap included in the distribution that allows you to use the same keystrokes as Pine would to send and receive mail. It's also under the GNU General Public License, version 2.0.

+

Of course, due to the license change you can now use the Alpine distribution of PINE as it is now considered Free Software, but you would be sacrificing many of nano's features to do so.

+
+ +

7. Miscellaneous

+

7.1. Where can I ask questions or send suggestions?

+

There are three mailing lists for nano hosted at Savannah: info-nano, help-nano and nano-devel. info-nano is a very low traffic list where new versions of nano are announced (surprise!). help-nano is for getting help with the editor without needing to hear all of the development issues surrounding it. nano-devel is a normally low, sometimes high traffic list for discussing the present and future development of nano. Here are links to where you can sign up for a given list:

+

info-nano - https://lists.gnu.org/mailman/listinfo/info-nano/
+ help-nano - https://lists.gnu.org/mailman/listinfo/help-nano/
+ nano-devel - https://lists.gnu.org/mailman/listinfo/nano-devel/

+

7.3. How do I submit a bug report or patch?

+
+

The best way to submit bugs is through the Savannah bug tracker, as you can check whether the bug you are reporting has already been submitted, and it makes it easier for the maintainers to keep track of them. +

You can submit patches for nano via Savannah's patch manager.

+

7.3. I want to send the development team a big load of cash (or just a thank you).

+

That's fine. Send it our way! Better yet, fix a bug in the program or implement a cool feature and send us that instead (though cash is fine too).

+

7.4. How do I join the development team?

+

The easiest way is to consistently send in good patches that add some needed functionality, fix a bug or two, and/or make the program more optimized/efficient. Then ask nicely and you will probably be added to the Savannah development list and be given write access after a while. There is a lot of responsibility that goes along with being a team member, so don't think it's just something to add to your resume.

+

7.5. Can I have write access to the git tree?

+

Re-read section 7.4 and you should know the answer.

It copies the look and feel +of Pico, but is free software, and implements several features that Pico +lacks, such as: opening multiple files, scrolling per line, undo/redo, +syntax coloring, line numbering, and soft-wrapping overlong lines. +.sp +When giving a filename on the command line, the cursor can be put on a +specific line by adding the line number with a plus sign (\fB+\fR) before +the filename, and even in a specific column by adding it with a comma. +(Negative numbers count from the end of the file or line.) +The cursor can be put on the first or last occurrence of a specific string +by specifying that string after \fB+/\fR or \fB+?\fR before the filename. +The string can be made case sensitive and/or caused to be interpreted as a +regular expression by inserting \fBc\fR and/or \fBr\fR after the \fB+\fR sign. +These search modes can be explicitly disabled by using the uppercase variant +of those letters: \fBC\fR and/or \fBR\fR. When the string contains spaces, +it needs to be enclosed in quotes. To give an example: to open a file at +the first occurrence of the word "Foo", you would do: +.sp +.RS 4 +.BI "nano +c/Foo " file +.RE +.sp +As a special case: if instead of a filename a dash (\fB\-\fR) is given, +\fBnano\fR will read data from standard input. + +.SH EDITING +Entering text and moving around in a file is straightforward: typing the +letters and using the normal cursor movement keys. Commands are entered +by using the Control (^) and the Alt or Meta (M\-) keys. +Typing \fB^K\fR deletes the current line and puts it in the cutbuffer. +Consecutive \fB^K\fRs will put all deleted lines together in the cutbuffer. +Any cursor movement or executing any other command will cause the next +\fB^K\fR to overwrite the cutbuffer. A \fB^U\fR will paste the current +contents of the cutbuffer at the current cursor position. +.sp +When a more precise piece of text needs to be cut or copied, you can mark +its start with \fB^6\fR, move the cursor to its end (the marked text will be +highlighted), and then use \fB^K\fR to cut it, or \fBM\-6\fR to copy it to the +cutbuffer. You can also save the marked text to a file with \fB^O\fR, or +spell check it with \fB^T^T\fR. +.sp +On some terminals, text can be selected also by holding down Shift while +using the arrow keys. Holding down the Ctrl or Alt key too will increase +the stride. +Any cursor movement without Shift being held will cancel such a selection. +.sp +Any valid Unicode code point can be inserted into the buffer by typing +\fBM\-V\fR followed by the hexadecimal digits of the code point (concluded +with \fB\fR or \fB\fR when it are fewer than six digits). +A literal control code (except \fB^J\fR) can be inserted by typing +\fBM\-V\fR followed by the pertinent keystroke. +.sp +The two lines at the bottom of the screen show some important commands; +the built-in help (\fB^G\fR) lists all the available ones. +The default key bindings can be changed via a \fInanorc\fR file -- see +.BR nanorc (5). + +.SH OPTIONS +.TP +.BR \-A ", " \-\-smarthome +Make the Home key smarter.

NAME + +

+ + +

nano - +Nano’s ANOther editor, inspired by Pico

+ +

SYNOPSIS + +

+ + +

nano +[options] +[[+line[,column]] +file]...

+ +

nano +[options] +[[+[crCR](/|?)string] +file]...

+ +

DESCRIPTION + +

+ + +

nano is +a small and friendly editor. It copies the look and feel of +Pico, but is free software, and implements several features +that Pico lacks, such as: opening multiple files, scrolling +per line, undo/redo, syntax coloring, line numbering, and +soft-wrapping overlong lines.

+ +

When giving a +filename on the command line, the cursor can be put on a +specific line by adding the line number with a plus sign +(+) before the filename, and even in a specific +column by adding it with a comma. (Negative numbers count +from the end of the file or line.) The cursor can be put on +the first or last occurrence of a specific string by +specifying that string after +/ or +? before +the filename. The string can be made case sensitive and/or +caused to be interpreted as a regular expression by +inserting c and/or r after the + sign. +These search modes can be explicitly disabled by using the +uppercase variant of those letters: C and/or +R. When the string contains spaces, it needs to be +enclosed in quotes. To give an example: to open a file at +the first occurrence of the word "Foo", you would +do:

+ +

nano ++c/Foo file

+ +

As a special +case: if instead of a filename a dash (-) is given, +nano will read data from standard input.

+ +

EDITING + +

+ + +

Entering text +and moving around in a file is straightforward: typing the +letters and using the normal cursor movement keys. Commands +are entered by using the Control (^) and the Alt or Meta +(M-) keys. Typing ^K deletes the current line and +puts it in the cutbuffer. Consecutive ^Ks will put +all deleted lines together in the cutbuffer. Any cursor +movement or executing any other command will cause the next +^K to overwrite the cutbuffer. A ^U will paste +the current contents of the cutbuffer at the current cursor +position.

+ +

When a more +precise piece of text needs to be cut or copied, you can +mark its start with ^6, move the cursor to its end +(the marked text will be highlighted), and then use +^K to cut it, or M-6 to copy it to the +cutbuffer. You can also save the marked text to a file with +^O, or spell check it with ^T^T.

+ +

On some +terminals, text can be selected also by holding down Shift +while using the arrow keys. Holding down the Ctrl or Alt key +too will increase the stride. Any cursor movement without +Shift being held will cancel such a selection.

+ +

Any valid +Unicode code point can be inserted into the buffer by typing +M-V followed by the hexadecimal digits of the code +point (concluded with <Space> or +<Enter> when it are fewer than six digits). A +literal control code (except ^J) can be inserted by +typing M-V followed by the pertinent keystroke.

+ +

The two lines +at the bottom of the screen show some important commands; +the built-in help (^G) lists all the available ones. +The default key bindings can be changed via a nanorc +file -- see nanorc(5).

+ +

OPTIONS + +

+ + +

-A, +--smarthome

+ +

Make the Home key smarter. When +Home is pressed anywhere but at the very beginning of +non-whitespace characters on a line, the cursor will jump to +that beginning (either forwards or backwards). If the cursor +is already at that position, it will jump to the true +beginning of the line.

+ +

-B, --backup

+ +

When saving a file, back up the +previous version of it, using the current filename suffixed +with a tilde (~).

+ + +

-C directory, +--backupdir=directory

+ +

Make and keep not just one +backup file, but make and keep a uniquely numbered one every +time a file is saved -- when backups are enabled +(-B). The uniquely numbered files are stored in the +specified directory.

+ +

-D, +--boldtext

+ +

For the interface, use bold +instead of reverse video. This will be overridden by setting +the options titlecolor, statuscolor, +keycolor, functioncolor, numbercolor, +and/or selectedcolor in your nanorc file. See +nanorc(5).

+ +

-E, +--tabstospaces

+ +

Convert each typed tab to +spaces -- to the number of spaces that a tab at that +position would take up.

+ +

-F, +--multibuffer

+ +

Read a file into a new buffer +by default.

+ +

-G, --locking

+ +

Use vim-style file locking when +editing files.

+ +

-H, +--historylog

+ +

Save the last hundred search +strings and replacement strings and executed commands, so +they can be easily reused in later sessions.

+ +

-I, +--ignorercfiles

+ +

Don’t look at the +system’s nanorc nor at the user’s +nanorc.

+ +

-J number, +--guidestripe=number

+ +

Draw a vertical stripe at the +given column, to help judge the width of the text. (The +color of the stripe can be changed with set +stripecolor in your nanorc file.)

+ +

-K, +--rawsequences

+ +

Interpret escape sequences +directly, instead of asking ncurses to translate +them. (If you need this option to get some keys to work +properly, it means that the terminfo terminal description +that is used does not fully match the actual behavior of +your terminal. This can happen when you ssh into a BSD +machine, for example.) Using this option disables +nano’s mouse support.

+ +

-L, +--nonewlines

+ +

Don’t automatically add a +newline when a text does not end with one. (This can cause +you to save non-POSIX text files.)

+ +

-M, +--trimblanks

+ +

Snip trailing whitespace from +the wrapped line when automatic hard-wrapping occurs or when +text is justified.

+ +

-N, +--noconvert

+ +

Disable automatic conversion of +files from DOS/Mac format.

+ +

-O, +--bookstyle

+ +

When justifying, treat any line +that starts with whitespace as the beginning of a paragraph +(unless auto-indenting is on).

+ +

-P, +--positionlog

+ +

For the 200 most recent files, +log the last position of the cursor, and place it at that +position again upon reopening such a file.

+ +

-Q +"regex", +--quotestr="regex"

+ +

Set the regular expression for +matching the quoting part of a line. The default value is +"^([ \t]*([!#%:;>|}]|//))+". (Note +that \t stands for an actual Tab.) This makes it +possible to rejustify blocks of quoted text when composing +email, and to rewrap blocks of line comments when writing +source code.

+ +

-R, +--restricted

+ +

Restricted mode: don’t +read or write to any file not specified on the command line. +This means: don’t read or write history files; +don’t allow suspending; don’t allow spell +checking; don’t allow a file to be appended to, +prepended to, or saved under a different name if it already +has one; and don’t make backup files. Restricted mode +can also be activated by invoking nano with any name +beginning with ’r’ (e.g. "rnano").

+ +

-S, +--softwrap

+ +

Display over multiple screen +rows lines that exceed the screen’s width. (You can +make this soft-wrapping occur at whitespace instead of +rudely at the screen’s edge, by using also +--atblanks.) (The old short option, -$, is +deprecated.)

+ +

-T number, +--tabsize=number

+ +

Set the size (width) of a tab +to number columns. The value of number must be +greater than 0. The default value is 8.

+ +

-U, +--quickblank

+ +

Make status-bar messages +disappear after 1 keystroke instead of after 20. Note that +option -c (--constantshow) overrides this. +When option --minibar or --zero is in effect, +--quickblank makes a message disappear after 0.8 +seconds instead of after the default 1.5 seconds.

+ +

-V, --version

+ +

Show the current version number +and exit.

+ +

-W, +--wordbounds

+ +

Detect word boundaries +differently by treating punctuation characters as part of a +word.

+ +

-X +"characters", +--wordchars="characters"

+ +

Specify which other characters +(besides the normal alphanumeric ones) should be considered +as part of a word. When using this option, you probably want +to omit -W (--wordbounds).

+ +

-Y name, +--syntax=name

+ +

Specify the name of the syntax +highlighting to use from among the ones defined in the +nanorc files.

+ +

-Z, --zap

+ +

Let an unmodified Backspace or +Delete erase the marked region (instead of a single +character, and without affecting the cutbuffer).

+ +

-a, +--atblanks

+ +

When doing soft line wrapping, +wrap lines at whitespace instead of always at the edge of +the screen.

+ +

-b, +--breaklonglines

+ +

Automatically hard-wrap the +current line when it becomes overlong. (This option is the +opposite of -w (--nowrap) -- the last one +given takes effect.)

+ +

-c, +--constantshow

+ +

Constantly show the cursor +position on the status bar. Note that this overrides option +-U (--quickblank).

+ +

-d, +--rebinddelete

+ +

Interpret the Delete and +Backspace keys differently so that both Backspace and Delete +work properly. You should only use this option when on your +system either Backspace acts like Delete or Delete acts like +Backspace.

+ +

-e, +--emptyline

+ +

Do not use the line below the +title bar, leaving it entirely blank.

+ +

-f file, +--rcfile=file

+ +

Read only this file for +setting nano’s options, instead of reading both the +system-wide and the user’s nanorc files.

+ +

-g, +--showcursor

+ +

Make the cursor visible in the +file browser (putting it on the highlighted item) and in the +help viewer. Useful for braille users and people with poor +vision.

+ +

-h, --help

+ +

Show a summary of the available +command-line options and exit.

+ +

-i, +--autoindent

+ +

Automatically indent a newly +created line to the same number of tabs and/or spaces as the +previous line (or as the next line if the previous line is +the beginning of a paragraph).

+ +

-j, +--jumpyscrolling

+ +

Scroll the buffer contents per +half-screen instead of per line.

+ +

-k, +--cutfromcursor

+ +

Make the ’Cut Text’ +command (normally ^K) cut from the current cursor +position to the end of the line, instead of cutting the +entire line.

+ +

-l, +--linenumbers

+ +

Display line numbers to the +left of the text area. (Any line with an anchor additionally +gets a mark in the margin.)

+ +

-m, --mouse

+ +

Enable mouse support, if +available for your system. When enabled, mouse clicks can be +used to place the cursor, set the mark (with a double +click), and execute shortcuts. The mouse will work in the X +Window System, and on the console when gpm is running. Text +can still be selected through dragging by holding down the +Shift key.

+ +

-n, --noread

+ +

Treat any name given on the +command line as a new file. This allows nano to write +to named pipes: it will start with a blank buffer, and will +write to the pipe when the user saves the "file". +This way nano can be used as an editor in combination +with for instance gpg without having to write +sensitive data to disk first.

+ + +

-o directory, +--operatingdir=directory

+ +

Set the operating directory. +This makes nano set up something similar to a +chroot.

+ +

-p, +--preserve

+ +

Preserve the XON and XOFF +sequences (^Q and ^S) so they will be caught +by the terminal.

+ +

-q, +--indicator

+ +

Display a "scrollbar" +on the righthand side of the edit window. It shows the +position of the viewport in the buffer and how much of the +buffer is covered by the viewport.

+ +

-r number, +--fill=number

+ +

Set the target width for +justifying and automatic hard-wrapping at this number +of columns. If the value is 0 or less, wrapping will occur +at the width of the screen minus number columns, +allowing the wrap point to vary along with the width of the +screen if the screen is resized. The default value is +-8.

+ +

-s "program +[argument ...]", +--speller="program [argument +...]"

+ +

Use this command to perform +spell checking and correcting, instead of using the built-in +corrector that calls hunspell(1) or +spell(1).

+ +

-t, +--saveonexit

+ +

Save a changed buffer without +prompting (when exiting with ^X).

+ +

-u, --unix

+ +

Save a file by default in Unix +format. This overrides nano’s default behavior of +saving a file in the format that it had. (This option has no +effect when you also use --noconvert.)

+ +

-v, --view

+ +

Just view the file and disallow +editing: read-only mode. This mode allows the user to open +also other files for viewing, unless --restricted is +given too.

+ +

-w, --nowrap

+ +

Do not automatically hard-wrap +the current line when it becomes overlong. This is the +default. (This option is the opposite of -b +(--breaklonglines) -- the last one given takes +effect.)

+ +

-x, --nohelp

+ +

Don’t show the two help +lines at the bottom of the screen.

+ +

-y, +--afterends

+ +

Make Ctrl+Right and Ctrl+Delete +stop at word ends instead of beginnings.

+ +

-!, --magic

+ +

When neither the file’s +name nor its first line give a clue, try using libmagic to +determine the applicable syntax.

+ +

-%, +--stateflags

+ +

Use the top-right corner of the +screen for showing some state flags: I when +auto-indenting, M when the mark is on, L when +hard-wrapping (breaking long lines), R when recording +a macro, and S when soft-wrapping. When the buffer is +modified, a star (*) is shown after the filename in +the center of the title bar.

+ +

-_, --minibar

+ +

Suppress the title bar and +instead show information about the current buffer at the +bottom of the screen, in the space for the status bar. In +this "minibar" the filename is shown on the left, +followed by an asterisk if the buffer has been modified. On +the right are displayed the current line and column number, +the code of the character under the cursor (in Unicode +format: U+xxxx), the same flags as are shown by +--stateflags, and a percentage that expresses how far +the cursor is into the file (linewise). When a file is +loaded or saved, and also when switching between buffers, +the number of lines in the buffer is displayed after the +filename. This number is cleared upon the next keystroke, or +replaced with an [i/n] counter when multiple buffers are +open. The line plus column numbers and the character code +are displayed only when --constantshow is used, and +can be toggled on and off with M-C. The state flags +are displayed only when --stateflags is used.

+ +

-0, --zero

+ +

Hide all elements of the +interface (title bar, status bar, and help lines) and use +all rows of the terminal for showing the contents of the +buffer. The status bar appears only when there is a +significant message, and disappears after 1.5 seconds or +upon the next keystroke. With M-Z the title bar plus +status bar can be toggled. With M-X the help +lines.

+ +

TOGGLES + +

+ + +

Several of the +above options can be switched on and off also while +nano is running. For example, M-L toggles the +hard-wrapping of long lines, M-S toggles +soft-wrapping, M-N toggles line numbers, M-M +toggles the mouse, M-I auto-indentation, and +M-X the help lines. See at the end of the ^G +help text for a complete list.

+ +

The M-X +toggle is special: it works in all menus except the help +viewer and the linter. All other toggles work in the main +menu only.

+ +

FILES + +

+ + +

When +--rcfile is given, nano will read just the +specified file for setting its options and syntaxes and key +bindings. Without that option, nano will read two +configuration files: first the system’s nanorc +(if it exists), and then the user’s nanorc (if +it exists), either ~/.nanorc or +$XDG_CONFIG_HOME/nano/nanorc or +~/.config/nano/nanorc, whichever is encountered +first. See nanorc(5) for more information on the +possible contents of those files.

+ +

See +/usr/share/nano/ and /usr/share/nano/extra/ +for available syntax-coloring definitions.

+ +

NOTES + +

+ + +

Option +-z (--suspendable) has been removed. +Suspension is enabled by default, reachable via ^T^Z. +(If you want a plain ^Z to suspend nano, add bind +^Z suspend main to your nanorc.)

+ +

If no +alternative spell checker command is specified on the +command line nor in one of the nanorc files, +nano will check the SPELL environment variable +for one.

+ +

In some cases +nano will try to dump the buffer into an emergency +file. This will happen mainly if nano receives a +SIGHUP or SIGTERM or runs out of memory. It will write the +buffer into a file named nano.save if the buffer +didn’t have a name already, or will add a +".save" suffix to the current filename. If an +emergency file with that name already exists in the current +directory, it will add ".save" plus a number (e.g. +".save.1") to the current filename in order to +make it unique. In multibuffer mode, nano will write +all the open buffers to their respective emergency +files.

+ +

BUGS + +

+ + +

The recording +and playback of keyboard macros works correctly only on a +terminal emulator, not on a Linux console (VT), because the +latter does not by default distinguish modified from +unmodified arrow keys.

+ +

Please report +any other bugs that you encounter via:
+https://savannah.gnu.org/bugs/?group=nano.

+ +

When nano +crashes, it will save any modified buffers to emergency +.save files. If you are able to reproduce the crash and you +want to get a backtrace, define the environment variable +NANO_NOCATCH.

1 Introduction

+ +

GNU nano is a small and friendly text editor. Besides +basic text editing, nano offers features like undo/redo, +syntax coloring, interactive search-and-replace, auto-indentation, +line numbers, word completion, file locking, backup files, and +internationalization support. +

+

The original goal for nano was to be a complete bug-for-bug +emulation of Pico. But currently the goal is to be as compatible +as is reasonable while offering a superset of Pico’s functionality. +See Pico Compatibility for more details on how nano and +Pico differ. +

+

Starting with version 4.0, nano no longer hard-wraps an overlong +line by default. It further uses linewise scrolling by default, and by +default includes the line below the title bar into the editing area. +If you want the old, Pico behavior back, you can use the +following options: --breaklonglines, +--jumpyscrolling, and --emptyline +(or -bje). +

+

Please report bugs via https://savannah.gnu.org/bugs/?group=nano. +

+

For background information see https://nano-editor.org/. +

+ +
+

2 Invoking

+ +

The usual way to invoke nano is: +

+
+
nano [FILE]
+
+ +

But it is also possible to specify one or more options (see Command-line Options), +and to edit several files in a row. Additionally, the cursor +can be put on a specific line of a file by adding the line number +with a plus sign before the filename, and even in a specific column by +adding it with a comma. +(Negative numbers count from the end of the file or line.) +The cursor can also be put on the first or last occurrence of a specific string +by specifying that string after +/ or +? before the filename. +The string can be made case sensitive and/or caused to be interpreted as a +regular expression by inserting a c and/or r after the plus sign. +These search modes can be explicitly disabled by using the uppercase variant +of those letters: C and/or R. When the string contains spaces, +it needs to be enclosed in quotes. +A more complete command synopsis thus is: +

+
+
nano [OPTION]… [[+LINE[,COLUMN]|+[crCR](/|?)STRING] FILE]…
+
+ +

Normally, however, you set your preferred options in a nanorc +file (see Nanorc Files). And when using set positionlog +(making nano remember the cursor position when you close a file), +you will rarely need to specify a line number. +

+

As a special case: when instead of a filename a dash is given, nano +will read data from standard input. This means you can pipe the output of +a command straight into a buffer, and then edit it. +

+ +
+

3 Editor Basics

• Screen Layout   +
• Entering Text   +
• Commands   +
• The Cutbuffer   +
• The Mark   +
• Search and Replace   +
• Using the Mouse   +
• Anchors   +
• Limitations   +
+ +
+

3.1 Screen Layout

+ +

The default screen of nano consists of four areas. +From top to bottom these are: the title bar, the edit window, +the status bar, and two help lines. +

+

The title bar consists of +three sections: left, center and right. The section on the left +displays the version of nano being used. The center section +displays the current filename, or "New Buffer" if the file has not yet +been named. The section on the right displays "Modified" if the +file has been modified since it was last saved or opened. +

+

The status bar is the third line from the bottom of the screen. It +shows important and informational messages. Any error messages that +occur from using the editor will appear on the status bar. Any questions +that are asked of the user will be asked on the status bar, and any user +input (search strings, filenames, etc.) will be input on the status bar. +

+

The two help lines at the bottom of the screen show some of the most +essential functions of the editor. +

+
+

3.2 Entering Text

+ +

nano is a "modeless" editor. This means that all keystrokes, +with the exception of Control and Meta sequences, enter text into the +file being edited. +

+

Characters not present on the keyboard can be entered in two ways: +

+
    +
  • For characters with a single-byte code, +pressing the Esc key twice and then typing a three-digit decimal number +(from 000 to 255) will make nano behave as if you +typed the key with that value. + +
  • For any possible character, pressing M-V (Alt+V) and then typing a +series of hexadecimal digits (at most six, or concluded with Enter or +Space) will enter the corresponding Unicode character into the buffer. +
+ +

For example, typing Esc Esc 2 3 4 will enter the character "ê" — +useful when writing about a French party. Typing M-V 0 0 2 2 c 4 +will enter the symbol "⋄", a little diamond. +

+

Typing M-V followed by anything other than a hexadecimal digit +will enter this keystroke verbatim into the buffer, allowing the user +to insert literal control codes (except ^J) or escape sequences. +

+
+

3.3 Commands

+ +

Commands are given by using the Control key (Ctrl, shown as ^) +or the Meta key (Alt or Cmd, shown as M-). +

+
    +
  • A control-key sequence is entered by holding down the Ctrl key and +pressing the desired key. + +
  • A meta-key sequence is entered by holding down the Meta key (normally +the Alt key) and pressing the desired key. +
+ +

If for some reason on your system the combinations with Ctrl or Alt do +not work, you can generate them by using the Esc key. A control-key +sequence is generated by pressing the Esc key twice and then pressing +the desired key, and a meta-key sequence by pressing the Esc key once +and then pressing the desired key. +

+
+

3.4 The Cutbuffer

+ +

Text can be cut from a file a whole line at a time with ^K. +The cut line is stored in the cutbuffer. Consecutive strokes of ^K +will add each cut line to this buffer, but a ^K +after any other keystroke will overwrite the entire cutbuffer. +

+

The contents of the cutbuffer can be pasted at the current cursor position +with ^U. +

+

A line of text can be copied into the cutbuffer (without cutting it) +with M-6. +

+
+

3.5 The Mark

+ +

Text can be selected by first ’setting the Mark’ with ^6 +or M-A and then moving the cursor to the other end of the portion +to be selected. The selected portion of text will be highlighted. +This selection can now be cut or copied in its entirety with a single +^K or M-6. Or the selection can be used to limit the scope of +a search-and-replace (^\) or spell-checking session (^T^T). +

+

On some terminals, text can be selected also by holding down Shift +while using the cursor keys. Holding down the Ctrl or Alt +key too will increase the stride. Such a selection is cancelled +upon any cursor movement where Shift isn’t held. +

+

Cutting or copying selected text toggles off the mark automatically. +If needed, it can be toggled off manually with another ^6 or M-A. +

+
+

3.6 Search and Replace

+ +

One can search the current buffer for the occurrence of any string +with the Search command (default key binding: ^W). The default search +mode is forward, case-insensitive, and for literal strings. But one +can search backwards by pressing M-B, search case sensitively with M-C, +and interpret regular expressions in the search string with M-R. +

+

A regular expression in a search string always covers just one line; +it cannot span multiple lines. And when replacing (with ^\ or M-R) +the replacement string cannot contain a newline (LF). +

+
+

3.7 Using the Mouse

+ +

When mouse support has been configured and enabled, a single mouse click +places the cursor at the indicated position. Clicking a second time in +the same position toggles the mark. Clicking in the two help lines +executes the selected shortcut. To be able to select text with the +left button, or paste text with the middle button, hold down the +Shift key during those actions. +

+

The mouse will work in the X Window System, and on the console when gpm +is running. +

+
+

3.8 Anchors

+ +

With M-Ins you can place an anchor (a kind of temporary bookmark) +at the current line. With M-PgUp and M-PgDn you can jump +to an anchor in the backward/forward direction. This jumping wraps +around at the top and bottom. +

+

When a line with an anchor is removed, the line where the cursor ends up +inherits the anchor. After performing an operation on the entire buffer +(like formatting it, piping it through a command, or doing an external +spell check on it), any anchors that were present are gone. And when +you close the buffer, all its anchors simply disappear; they are not saved. +

+

Anchors are visualized in the margin when line numbers are activated. +

+
+

3.9 Limitations

+ +

The recording and playback of keyboard macros works correctly only on a +terminal emulator, not on a Linux console (VT), because the latter does +not by default distinguish modified from unmodified arrow keys. +

+ +
+

4 The Help Viewer

+ +

The built-in help in nano is available by pressing ^G. +It is fairly self-explanatory. It documents the various parts of the +editor and the available keystrokes. Navigation is via the ^Y (Page Up) +and ^V (Page Down) keys. ^X exits from the help viewer. +

+ +
+

5 The File Browser

+ +

When in the Read-File (^R) or Write-Out menu (^O), +pressing ^T will invoke the file browser. +Here, one can navigate directories in a graphical manner in order to +find the desired file. +

+

Basic movement in the file browser is accomplished with the arrow and +other cursor-movement keys. More targeted movement is accomplished by +searching, via ^W or w, or by changing directory, via +^_ or g. The behavior of the Enter key (or s) +varies by what is currently selected. +If the currently selected object is a directory, the file browser will +enter and display the contents of the directory. If the object is a +file, this filename and path are copied to the status bar, and the file +browser exits. +

+ +
+

6 Command-line Options

+ +

nano takes the following options from the command line: +

+
+
-A
+
--smarthome
+

Make the Home key smarter. When Home is pressed anywhere but at the +very beginning of non-whitespace characters on a line, the cursor will +jump to that beginning (either forwards or backwards). If the cursor is +already at that position, it will jump to the true beginning of the +line. +

+
+
-B
+
--backup
+

When saving a file, back up the previous version of it, using the current +filename suffixed with a tilde (~). +

+
+
-C directory
+
--backupdir=directory
+

Make and keep not just one backup file, but make and keep a uniquely +numbered one every time a file is saved — when backups are enabled. +The uniquely numbered files are stored in the specified directory. +

+
+
-D
+
--boldtext
+

For the interface, use bold instead of reverse video. This will be overridden +by setting the options titlecolor, statuscolor, keycolor, +functioncolor, numbercolor, and/or selectedcolor in your +nanorc file. See set keycolor for details. +

+
+
-E
+
--tabstospaces
+

Convert each typed tab to spaces — to the number of spaces +that a tab at that position would take up. +

+
+
-F
+
--multibuffer
+

Read a file into a new buffer by default. +

+
+
-G
+
--locking
+

Enable vim-style file locking when editing files. +

+
+
-H
+
--historylog
+

Save the last hundred search strings and replacement strings and +executed commands, so they can be easily reused in later sessions. +

+
+
-I
+
--ignorercfiles
+

Don’t look at the system’s nanorc file nor at the user’s nanorc. +

+
+
-J
+
--guidestripe
+

Draw a vertical stripe at the given column, to help judge the width of the +text. (The color of the stripe can be changed with set stripecolor +in your nanorc file.) +

+
+
-K
+
--rawsequences
+

Interpret escape sequences directly, instead of asking ncurses +to translate them. (If you need this option to get some keys to work +properly, it means that the terminfo terminal description that is used +does not fully match the actual behavior of your terminal. This can +happen when you ssh into a BSD machine, for example.) +Using this option disables nano’s mouse support. +

+
+
-L
+
--nonewlines
+

Don’t automatically add a newline when a text does not end with one. +(This can cause you to save non-POSIX text files.) +

+
+
-M
+
--trimblanks
+

Snip trailing whitespace from the wrapped line when automatic +hard-wrapping occurs or when text is justified. +

+
+
-N
+
--noconvert
+

Disable automatic conversion of files from DOS/Mac format. +

+
+
-O
+
--bookstyle
+

When justifying, treat any line that starts with whitespace as the +beginning of a paragraph (unless auto-indenting is on). +

+
+
-P
+
--positionlog
+

For the 200 most recent files, log the last position of the cursor, +and place it at that position again upon reopening such a file. +

+
+
-Q "regex"
+
--quotestr="regex"
+

Set the regular expression for matching the quoting part of a line. +The default value is "^([ \t]*([!#%:;>|}]|//))+". +(Note that \t stands for a literal Tab character.) +This makes it possible to rejustify blocks of quoted text when composing +email, and to rewrap blocks of line comments when writing source code. +

+
+
-R
+
--restricted
+

Restricted mode: don’t read or write to any file not specified on the +command line. This means: don’t read or write history files; don’t allow +suspending; don’t allow spell checking; don’t +allow a file to be appended to, prepended to, or saved under a different +name if it already has one; and don’t make backup files. +Restricted mode can also be activated by invoking nano with +any name beginning with r (e.g. rnano). +

+
+
-S
+
--softwrap
+

Display over multiple screen rows lines that exceed the screen’s width. +(You can make this soft-wrapping occur at whitespace instead of rudely at +the screen’s edge, by using also --atblanks.) +(The old short option, -$, is deprecated.) +

+
+
-T number
+
--tabsize=number
+

Set the displayed tab length to number columns. The value of +number must be greater than 0. The default value is 8. +

+
+
-U
+
--quickblank
+

Make status-bar messages disappear after 1 keystroke instead of after 20. +Note that option -c (--constantshow) overrides this. +When option --minibar or --zero is in effect, +--quickblank makes a message disappear after +0.8 seconds instead of after the default 1.5 seconds. +

+
+
-V
+
--version
+

Show the current version number and exit. +

+
+
-W
+
--wordbounds
+

Detect word boundaries differently by treating punctuation +characters as parts of words. +

+
+
-X "characters"
+
--wordchars="characters"
+

Specify which other characters (besides the normal alphanumeric ones) +should be considered as parts of words. When using this option, you +probably want to omit -W (--wordbounds). +

+
+
-Y name
+
--syntax=name
+

Specify the syntax to be used for highlighting. +See Syntax Highlighting for more info. +

+
+
-Z
+
--zap
+

Let an unmodified Backspace or Delete erase the marked region +(instead of a single character, and without affecting the cutbuffer). +

+
+
-a
+
--atblanks
+

When doing soft line wrapping, wrap lines at whitespace +instead of always at the edge of the screen. +

+
+
-b
+
--breaklonglines
+

Automatically hard-wrap the current line when it becomes overlong. +(This option is the opposite of -w (--nowrap) — +the last one given takes effect.) +

+
+
-c
+
--constantshow
+

Constantly display the cursor position (line number, column number, +and character number) on the status bar. +Note that this overrides option -U (--quickblank). +

+
+
-d
+
--rebinddelete
+

Interpret the Delete and Backspace keys differently so that +both work properly. You should only use this option when on your system +either Backspace acts like Delete or Delete acts like Backspace. +

+
+
-e
+
--emptyline
+

Do not use the line below the title bar, leaving it entirely blank. +

+
+
-f file
+
--rcfile=file
+

Read only this file for setting nano’s options, instead of reading +both the system-wide and the user’s nanorc files. +

+
+
-g
+
--showcursor
+

Make the cursor visible in the file browser (putting it on the +highlighted item) and in the help viewer. Useful for braille users +and people with poor vision. +

+
+
-h
+
--help
+

Show a summary of command-line options and exit. +

+
+
-i
+
--autoindent
+

Automatically indent a newly created line to the same number of tabs +and/or spaces as the previous line (or as the next line if the previous +line is the beginning of a paragraph). +

+
+
-j
+
--jumpyscrolling
+

Scroll the buffer contents per half-screen instead of per line. +

+
+
-k
+
--cutfromcursor
+

Make the ’Cut Text’ command (normally ^K) cut from the current cursor +position to the end of the line, instead of cutting the entire line. +

+
+
-l
+
--linenumbers
+

Display line numbers to the left of the text area. +(Any line with an anchor additionally gets a mark in the margin.) +

+
+
-m
+
--mouse
+

Enable mouse support, if available for your system. When enabled, mouse +clicks can be used to place the cursor, set the mark (with a double +click), and execute shortcuts. The mouse will work in the X Window +System, and on the console when gpm is running. Text can still be +selected through dragging by holding down the Shift key. +

+
+
-n
+
--noread
+

Treat any name given on the command line as a new file. This allows +nano to write to named pipes: it will start with a blank buffer, +and will write to the pipe when the user saves the "file". This way +nano can be used as an editor in combination with for instance +gpg without having to write sensitive data to disk first. +

+
+
-o directory
+
--operatingdir=directory
+

Set the operating directory. This makes nano set up something +similar to a chroot. +

+
+
-p
+
--preserve
+

Preserve the ^Q (XON) and ^S (XOFF) sequences so data being +sent to the editor can be stopped and started. +

+
+
-q
+
--indicator
+

Display a "scrollbar" on the righthand side of the edit window. +It shows the position of the viewport in the buffer +and how much of the buffer is covered by the viewport. +

+
+
-r number
+
--fill=number
+

Set the target width for justifying and automatic hard-wrapping at this +number of columns. If the value is 0 or less, wrapping will occur +at the width of the screen minus number columns, allowing the wrap +point to vary along with the width of the screen if the screen is resized. +The default value is -8. +

+
+
-s "program [argument …]"
+
--speller="program [argument …]"
+

Use the given program to do spell checking and correcting. By default, +nano uses the command specified in the SPELL environment +variable. If SPELL is not set, and --speller is +not specified either, then nano uses its own interactive spell +corrector, which requires either hunspell or GNU spell +to be installed. +

+
+
-t
+
--saveonexit
+

Save a changed buffer without prompting (when exiting with ^X). +This can be handy when nano is used as the composer of an +email program. +

+
+
-u
+
--unix
+

Save a file by default in Unix format. This overrides nano’s +default behavior of saving a file in the format that it had. +(This option has no effect when you also use --noconvert.) +

+
+
-v
+
--view
+

Don’t allow the contents of the file to be altered: read-only mode. +This mode allows the user to open also other files for viewing, +unless --restricted is given too. +(Note that this option should NOT be used in place of correct +file permissions to implement a read-only file.) +

+
+
-w
+
--nowrap
+

Do not automatically hard-wrap the current line when it becomes overlong. +This is the default. (This option is the opposite of -b +(--breaklonglines) — the last one given takes effect.) +

+ +
+
-x
+
--nohelp
+

Expert mode: don’t show the two help lines at the bottom of the screen. +This affects the location of the status bar as well, as in Expert mode it +is located at the very bottom of the editor. +

+

Note: When accessing the help system, Expert mode is temporarily +disabled to display the help-system navigation keys. +

+
+
-y
+
--afterends
+

Make Ctrl+Right and Ctrl+Delete stop at word ends +instead of beginnings. +

+
+
-!
+
--magic
+

When neither the file’s name nor its first line give a clue, +try using libmagic to determine the applicable syntax. +

+
+
-%
+
--stateflags
+

Use the top-right corner of the screen for showing some state flags: +I when auto-indenting, M when the mark is on, L when +hard-wrapping (breaking long lines), R when recording a macro, +and S when soft-wrapping. +When the buffer is modified, a star (*) is shown after the +filename in the center of the title bar. +

+
+
-_
+
--minibar
+

Suppress the title bar and instead show information about +the current buffer at the bottom of the screen, in the space +for the status bar. In this "minibar" the filename is shown +on the left, followed by an asterisk if the buffer has been modified. +On the right are displayed the current line and column number, the +code of the character under the cursor (in Unicode format: U+xxxx), +the same flags as are shown by --stateflags, and a percentage +that expresses how far the cursor is into the file (linewise). +When a file is loaded or saved, and also when switching between buffers, +the number of lines in the buffer is displayed after the filename. +This number is cleared upon the next keystroke, or replaced with an +[i/n] counter when multiple buffers are open. +The line plus column numbers and the character code are displayed only when +--constantshow is used, and can be toggled on and off with M-C. +The state flags are displayed only when --stateflags is used. +

+
+
-0
+
--zero
+

Hide all elements of the interface (title bar, status bar, and help lines) +and use all rows of the terminal for showing the contents of the buffer. +The status bar appears only when there is a significant message, +and disappears after 1.5 seconds or upon the next keystroke. +With M-Z the title bar plus status bar can be toggled. +With M-X the help lines. +

+
+
+ +
+

Option -z (--suspendable) has been removed. +Suspension is enabled by default, reachable via ^T^Z. +(If you want a plain ^Z to suspend nano, add +bind ^Z suspend main to your nanorc.) +

+ +
+

7 Feature Toggles

+ +

Toggles allow you to change certain aspects of the editor while you are +editing, aspects that you would normally specify via command-line options +or nanorc options. Each toggle can be flicked via a Meta-key combination +— the Meta key is normally the Alt key (see Commands +for more details). The following global toggles are available: +

+
+
+
Constant Cursor Position Display
+

M-C toggles the -c (--constantshow) command-line option. +

+
+
Smart Home Key
+

M-H toggles the -A (--smarthome) command-line option. +

+
+
Auto Indent
+

M-I toggles the -i (--autoindent) command-line option. +

+
+
Cut From Cursor To End-of-Line
+

M-K toggles the -k (--cutfromcursor) command-line option. +

+
+
Long-Line Wrapping
+

M-L toggles the -b (--breaklonglines) command-line option. +

+
+
Mouse Support
+

M-M toggles the -m (--mouse) command-line option. +

+
+
Line Numbers
+

M-N toggles the -l (--linenumbers) command-line option. +

+
+
Tabs To Spaces
+

M-O toggles the -E (--tabstospaces) command-line option. +

+
+
Whitespace Display
+

M-P toggles the displaying of whitespace (see Whitespace). +

+
+
Soft Wrapping
+

M-S toggles the -S (--softwrap) command-line option. +

+
+
Expert
+

M-X toggles the -x (--nohelp) command-line option. +

+
+
Syntax Coloring
+

M-Y toggles syntax coloring, when your nanorc defines syntaxes +(see Syntax Highlighting). +

+
+
Hidden Interface
+

M-Z toggles the -0 (--zero) command-line option, +but without the -x (--nohelp) part. That is: it toggles +just the title bar plus status bar (or the combined minibar plus status bar), +not the help lines. The latter are toggled with M-X. +

+
+
+ + +
+

8 Nanorc Files

+ +

Nanorc files can be used to configure nano to your liking +without using command-line options. During startup nano will +normally read two files: first the system-wide file, /etc/nanorc +(the exact path may be different on your system), and then the user-specific +file, either ~/.nanorc or $XDG_CONFIG_HOME/nano/nanorc or +.config/nano/nanorc, whichever exists first. +However, if --rcfile is given, nano will skip the +above files and will read just the specified settings file. +

+

A nanorc file can contain set and unset commands for +various options (see Settings). It can also contain commands that +define syntax highlighting (see Syntax Highlighting) and commands +that rebind keys (Rebinding Keys). Each command should be on a +separate line, and all commands should be written in lowercase. +

+

Options that do not take an argument are unset by default. So using +the unset command is only needed when wanting to override a +setting from the system’s nanorc file in your own nanorc. Options that +take an argument cannot be unset, but can be assigned the empty string. +

+

Any command-line option overrides its nanorc setting, of course. +

+

Quotes inside the characters parameters below should not be escaped. +The last double quote on the line will be seen as the closing quote. +

+ + + + +
• Settings   +
• Syntax Highlighting   +
• Rebinding Keys   +
+ +
+

8.1 Settings

+ +

The supported settings in a nanorc file are: +

+
+
set afterends
+

Make Ctrl+Right and Ctrl+Delete stop at word ends +instead of beginnings. +

+
+
set allow_insecure_backup
+

When backing up files, allow the backup to succeed even if its +permissions can’t be (re)set due to special OS considerations. +You should NOT enable this option unless you are sure you need it. +

+
+
set atblanks
+

When soft line wrapping is enabled, make it wrap lines at blank characters +(tabs and spaces) instead of always at the edge of the screen. +

+
+
set autoindent
+

Automatically indent a newly created line to the same number of tabs +and/or spaces as the previous line (or as the next line if the previous +line is the beginning of a paragraph). +

+
+
set backup
+

When saving a file, back up the previous version of it, using the current +filename suffixed with a tilde (~). +

+
+
set backupdir "directory"
+

Make and keep not just one backup file, but make and keep a uniquely +numbered one every time a file is saved — when backups are enabled +with set backup or --backup or -B. +The uniquely numbered files are stored in the specified directory. +

+
+
set boldtext
+

Use bold instead of reverse video for the title bar, status bar, key combos, +function tags, line numbers, and selected text. This is overridden by +setting the options titlecolor, statuscolor, keycolor, +functioncolor, numbercolor, and/or selectedcolor. +

+
+
set bookstyle
+

When justifying, treat any line that starts with whitespace as the +beginning of a paragraph (unless auto-indenting is on). +

+
+
set brackets "characters"
+

Set the characters treated as closing brackets when justifying +paragraphs. This may not include blank characters. Only closing +punctuation (see set punct), optionally followed by the specified +closing brackets, can end sentences. The default value is +""')>]}". +

+
+
set breaklonglines
+

Automatically hard-wrap the current line when it becomes overlong. +

+
+
set casesensitive
+

Do case-sensitive searches by default. +

+
+
set constantshow
+

Constantly display the cursor position on the status bar. +Note that this overrides quickblank. +

+
+
set cutfromcursor
+

Use cut-from-cursor-to-end-of-line by default, instead of cutting the whole line. +

+
+
set emptyline
+

Do not use the line below the title bar, leaving it entirely blank. +

+
+
set errorcolor [bold,][italic,]fgcolor,bgcolor
+

Use this color combination for the status bar when an error message is displayed. +The default value is bold,white,red. +See set keycolor for valid color names. +

+
+
set fill number
+

Set the target width for justifying and automatic hard-wrapping at this +number of columns. If the value is 0 or less, wrapping will occur +at the width of the screen minus number columns, allowing the wrap +point to vary along with the width of the screen if the screen is resized. +The default value is -8. +

+
+
set functioncolor [bold,][italic,]fgcolor,bgcolor
+

Use this color combination for the concise function descriptions +in the two help lines at the bottom of the screen. +See set keycolor for valid color names. +

+
+
set guidestripe number
+

Draw a vertical stripe at the given column, to help judge the width of the +text. (The color of the stripe can be changed with set stripecolor.) +

+
+
set historylog
+

Save the last hundred search strings and replacement strings and +executed commands, so they can be easily reused in later sessions. +

+
+
set indicator
+

Display a "scrollbar" on the righthand side of the edit window. +It shows the position of the viewport in the buffer +and how much of the buffer is covered by the viewport. +

+
+
set jumpyscrolling
+

Scroll the buffer contents per half-screen instead of per line. +

+
+
set keycolor [bold,][italic,]fgcolor,bgcolor
+

Use this color combination for the shortcut key combos +in the two help lines at the bottom of the screen. +Valid names for the foreground and background colors are: +red, green, blue, +magenta, yellow, cyan, +white, and black. +Each of these eight names may be prefixed with the word +light to get a brighter version of that color. +The word grey or gray may be used +as a synonym for lightblack. +

+

On terminal emulators that can do at least 256 colors, +other valid (but unprefixable) color names are: +pink, purple, mauve, +lagoon, mint, lime, +peach, orange, latte, +rosy, beet, plum, sea, +sky, slate, teal, sage, +brown, ocher, sand, tawny, +brick, crimson, and normal +— where normal means the default foreground or background color. +On such emulators, the color may also be specified as a three-digit hexadecimal +number prefixed with #, with the digits representing the amounts of red, +green, and blue, respectively. This tells nano to select from the +available palette the color that approximates the given values. +

+

Either fgcolor or ,bgcolor may be left out, +and the pair may be preceded by bold and/or italic +(separated by commas) to get a bold and/or slanting typeface, +if your terminal can do those. +

+
+
set linenumbers
+

Display line numbers to the left of the text area. +(Any line with an anchor additionally gets a mark in the margin.) +

+
+
set locking
+

Enable vim-style lock-files for when editing files. +

+
+
set magic
+

When neither the file’s name nor its first line give a clue, +try using libmagic to determine the applicable syntax. +(Calling libmagic can be relatively time consuming. +It is therefore not done by default.) +

+
+
set matchbrackets "characters"
+

Specify the opening and closing brackets that can be found by bracket +searches. This may not include blank characters. The opening set must +come before the closing set, and the two sets must be in the same order. +The default value is "(<[{)>]}". +

+
+
set minibar
+

Suppress the title bar and instead show information about +the current buffer at the bottom of the screen, in the space +for the status bar. In this "minibar" the filename is shown +on the left, followed by an asterisk if the buffer has been modified. +On the right are displayed the current line and column number, the +code of the character under the cursor (in Unicode format: U+xxxx), +the same flags as are shown by set stateflags, and a percentage +that expresses how far the cursor is into the file (linewise). +When a file is loaded or saved, and also when switching between buffers, +the number of lines in the buffer is displayed after the filename. +This number is cleared upon the next keystroke, or replaced with an +[i/n] counter when multiple buffers are open. +The line plus column numbers and the character code are displayed only when +set constantshow is used, and can be toggled on and off with M-C. +The state flags are displayed only when set stateflags is used. +

+
+
set minicolor [bold,][italic,]fgcolor,bgcolor
+

Use this color combination for the minibar. +(When this option is not specified, the colors of the title bar are used.) +See set keycolor for valid color names. +

+
+
set mouse
+

Enable mouse support, so that mouse clicks can be used to place the +cursor, set the mark (with a double click), or execute shortcuts. +

+
+
set multibuffer
+

When reading in a file with ^R, insert it into a new buffer by default. +

+
+
set noconvert
+

Don’t convert files from DOS/Mac format. +

+
+
set nohelp
+

Don’t display the help lists at the bottom of the screen. +

+
+
set nonewlines
+

Don’t automatically add a newline when a text does not end with one. +(This can cause you to save non-POSIX text files.) +

+
+
set nowrap
+

Deprecated option since it has become the default setting. +When needed, use unset breaklonglines instead. +

+
+
set numbercolor [bold,][italic,]fgcolor,bgcolor
+

Use this color combination for line numbers. +See set keycolor for valid color names. +

+
+
set operatingdir "directory"
+

nano will only read and write files inside "directory" and its +subdirectories. Also, the current directory is changed to here, so +files are inserted from this directory. By default, the operating +directory feature is turned off. +

+
+
set positionlog
+

Save the cursor position of files between editing sessions. +The cursor position is remembered for the 200 most-recently edited files. +

+
+
set preserve
+

Preserve the XON and XOFF keys (^Q and ^S). +

+
+
set promptcolor [bold,][italic,]fgcolor,bgcolor
+

Use this color combination for the prompt bar. +(When this option is not specified, the colors of the title bar are used.) +See set keycolor for valid color names. +

+
+
set punct "characters"
+

Set the characters treated as closing punctuation when justifying +paragraphs. This may not include blank characters. Only the +specified closing punctuation, optionally followed by closing brackets +(see set brackets), can end sentences. +The default value is "!.?". +

+
+
set quickblank
+

Make status-bar messages disappear after 1 keystroke instead of after 20. +Note that option constantshow overrides this. +When option minibar or zero is in effect, +quickblank makes a message disappear after +0.8 seconds instead of after the default 1.5 seconds. +

+
+
set quotestr "regex"
+

Set the regular expression for matching the quoting part of a line. +The default value is "^([ \t]*([!#%:;>|}]|//))+". +(Note that \t stands for a literal Tab character.) +This makes it possible to rejustify blocks of quoted text when composing +email, and to rewrap blocks of line comments when writing source code. +

+
+
set rawsequences
+

Interpret escape sequences directly, instead of asking ncurses +to translate them. (If you need this option to get some keys to work +properly, it means that the terminfo terminal description that is used +does not fully match the actual behavior of your terminal. This can +happen when you ssh into a BSD machine, for example.) +Using this option disables nano’s mouse support. +

+
+
set rebinddelete
+

Interpret the Delete and Backspace keys differently so that +both work properly. You should only use this option when on your system +either Backspace acts like Delete or Delete acts like Backspace. +

+
+
set regexp
+

Do regular-expression searches by default. +Regular expressions in nano are of the extended type (ERE). +

+
+
set saveonexit
+

Save a changed buffer automatically on exit (^X); don’t prompt. +

+
+
set scrollercolor fgcolor,bgcolor
+

Use this color combination for the indicator alias "scrollbar". +(On terminal emulators that link to a libvte older than version 0.55, +using a background color here does not work correctly.) +See set keycolor for valid color names. +

+
+
set selectedcolor [bold,][italic,]fgcolor,bgcolor
+

Use this color combination for selected text. +See set keycolor for valid color names. +

+
+
set showcursor
+

Put the cursor on the highlighted item in the file browser, and show +the cursor in the help viewer, to aid braille users and people with +poor vision. +

+
+
set smarthome
+

Make the Home key smarter. When Home is pressed anywhere but at the +very beginning of non-whitespace characters on a line, the cursor will +jump to that beginning (either forwards or backwards). If the cursor is +already at that position, it will jump to the true beginning of the +line. +

+
+
set softwrap
+

Display lines that exceed the screen’s width over multiple screen lines. +(You can make this soft-wrapping occur at whitespace instead of rudely at +the screen’s edge, by using also set atblanks.) +

+
+
set speller "program [argument …]"
+

Use the given program to do spell checking and correcting. +See --speller for details. +

+
+
set spotlightcolor [bold,][italic,]fgcolor,bgcolor
+

Use this color combination for highlighting a search match. +The default value is black,lightyellow. +See set keycolor for valid color names. +

+
+
set stateflags
+

Use the top-right corner of the screen for showing some state flags: +I when auto-indenting, M when the mark is on, L when +hard-wrapping (breaking long lines), R when recording a macro, +and S when soft-wrapping. +When the buffer is modified, a star (*) is shown after the +filename in the center of the title bar. +

+
+
set statuscolor [bold,][italic,]fgcolor,bgcolor
+

Use this color combination for the status bar. +See set keycolor for valid color names. +

+
+
set stripecolor [bold,][italic,]fgcolor,bgcolor
+

Use this color combination for the vertical guiding stripe. +See set keycolor for valid color names. +

+
+
set tabsize number
+

Use a tab size of number columns. The value of number must be +greater than 0. The default value is 8. +

+
+
set tabstospaces
+

Convert each typed tab to spaces — to the number of spaces +that a tab at that position would take up. +

+
+
set titlecolor [bold,][italic,]fgcolor,bgcolor
+

Use this color combination for the title bar. +See set keycolor for valid color names. +

+
+
set trimblanks
+

Remove trailing whitespace from wrapped lines when automatic +hard-wrapping occurs or when text is justified. +

+
+
set unix
+

Save a file by default in Unix format. This overrides nano’s +default behavior of saving a file in the format that it had. +(This option has no effect when you also use set noconvert.) +

+
+
set whitespace "characters"
+

Set the two characters used to indicate the presence of tabs and +spaces. They must be single-column characters. The default pair +for a UTF-8 locale is "»·", and for other locales ">.". +

+
+
set wordbounds
+

Detect word boundaries differently by treating punctuation +characters as part of a word. +

+
+
set wordchars "characters"
+

Specify which other characters (besides the normal alphanumeric ones) +should be considered as parts of words. When using this option, you +probably want to unset wordbounds. +

+
+
set zap
+

Let an unmodified Backspace or Delete erase the marked region +(instead of a single character, and without affecting the cutbuffer). +

+
+
set zero
+

Hide all elements of the interface (title bar, status bar, and help lines) +and use all rows of the terminal for showing the contents of the buffer. +The status bar appears only when there is a significant message, +and disappears after 1.5 seconds or upon the next keystroke. +With M-Z the title bar plus status bar can be toggled. +With M-X the help lines. +

+
+
+ +
+

8.2 Syntax Highlighting

+ +

Coloring the different syntactic elements of a file +is done via regular expressions (see the color command below). +This is inherently imperfect, because regular expressions are not +powerful enough to fully parse a file. Nevertheless, regular +expressions can do a lot and are easy to make, so they are a +good fit for a small editor like nano. +

+

See /usr/share/nano/ and /usr/share/nano/extra/ +for the syntax-coloring definitions that are available out of the box. +

+

All regular expressions in nano are POSIX extended regular expressions +(ERE). This means that ., ?, *, +, ^, +$, and several other characters are special. +The period . matches any single character, +? means the preceding item is optional, +* means the preceding item may be matched zero or more times, ++ means the preceding item must be matched one or more times, +^ matches the beginning of a line, and $ the end, +\< matches the start of a word, and \> the end, +and \s matches a blank. +It also means that lookahead and lookbehind are not possible. +A complete explanation can be found in the manual of GNU grep: +info grep regular. +

+

Each regular expression in a nanorc file should be wrapped in +double quotes (""). Multiple regular expressions can follow +each other on a line by separating them with blanks. This means that +a regular expression cannot contain a double quote followed by a blank. +When you need this combination inside a regular expression, +then either the double quote or the blank should be put +between square brackets ([]). +

+

A separate syntax can be defined for each kind of file +via the following commands in a nanorc file: +

+
+
syntax name ["fileregex" …]
+

Start the definition of a syntax with this name. +All subsequent color and other such commands +will be added to this syntax, until a new syntax +command is encountered. +

+

When nano is run, this syntax will be automatically +activated if the current filename matches the extended regular +expression fileregex. Or the syntax can be explicitly +activated by using the -Y or --syntax +command-line option followed by the name. +

+

The default syntax is special: it takes no fileregex, +and applies to files that don’t match any syntax’s regexes. +The none syntax is reserved; specifying it on the +command line is the same as not having a syntax at all. +

+
+
header "regex" …
+

If from all defined syntaxes no fileregex matched, then compare +this regex (or regexes) against the first line of the current file, +to determine whether this syntax should be used for it. +

+
+
magic "regex" …
+

If no fileregex matched and no header regex matched +either, then compare this regex (or regexes) against the +result of querying the magic database about the current +file, to determine whether this syntax should be used for it. +(This functionality only works when libmagic is installed +on the system and will be silently ignored otherwise.) +

+
+
formatter program [argument …]
+

Run the given program on the full contents of the current buffer. +

+
+
linter program [argument …]
+

Use the given program to do a syntax check on the current buffer. +

+
+
comment "string"
+

Use the given string for commenting and uncommenting lines. +If the string contains a vertical bar or pipe character (|), +this designates bracket-style comments; for example, "/*|*/" for +CSS files. The characters before the pipe are prepended to the line and the +characters after the pipe are appended at the end of the line. If no pipe +character is present, the full string is prepended; for example, "#" for +Python files. If empty double quotes are specified, the comment/uncomment +functions are disabled; for example, "" for JSON. +The default value is "#". +

+
+
tabgives "string"
+

Make the <Tab> key produce the given string. Useful for languages like +Python that want to see only spaces for indentation. +This overrides the setting of the tabstospaces option. +

+
+
color [bold,][italic,]fgcolor,bgcolor "regex" …
+

Paint all pieces of text that match the extended regular expression "regex" +with the given foreground and background colors, at least one of which must +be specified. Valid color names are: +red, green, blue, +magenta, yellow, cyan, +white, and black. +Each of these eight names may be prefixed with the word +light to get a brighter version of that color. +The word grey or gray may be used +as a synonym for lightblack. +

+

On terminal emulators that can do at least 256 colors, +other valid (but unprefixable) color names are: +pink, purple, mauve, +lagoon, mint, lime, +peach, orange, latte, +rosy, beet, plum, sea, +sky, slate, teal, sage, +brown, ocher, sand, tawny, +brick, crimson, and normal +— where normal means the default foreground or background color. +On such emulators, the color may also be specified as a three-digit hexadecimal +number prefixed with #, with the digits representing the amounts of red, +green, and blue, respectively. This tells nano to select from the +available palette the color that approximates the given values. +

+

The color pair may be preceded by bold and/or italic +(separated by commas) to get a bold and/or slanting typeface, +if your terminal can do those. +

+

All coloring commands are applied in the order in which they are specified, +which means that later commands can recolor stuff that was colored earlier. +

+
+
icolor [bold,][italic,]fgcolor,bgcolor "regex" …
+

Same as above, except that the matching is case insensitive. +

+
+
color [bold,][italic,]fgcolor,bgcolor start="fromrx" end="torx"
+

Paint all pieces of text whose start matches extended regular expression +"fromrx" and whose end matches extended regular expression "torx" with +the given foreground and background colors, at least one of +which must be specified. This means that, after an initial instance of +"fromrx", all text until the first instance of "torx" will be colored. +This allows syntax highlighting to span multiple lines. +

+
+
icolor [bold,][italic,]fgcolor,bgcolor start="fromrx" end="torx"
+

Same as above, except that the matching is case insensitive. +

+
+
include "syntaxfile"
+

Read in self-contained color syntaxes from "syntaxfile". Note that +"syntaxfile" may contain only the above commands, from syntax +to icolor. +

+
+
extendsyntax name command argument …
+

Extend the syntax previously defined as "name" with another command. +This allows you to add a new color, icolor, header, +magic, formatter, linter, comment, +or tabgives command to an already +defined syntax — useful when you want to slightly improve a syntax defined +in one of the system-installed files (which normally are not writable). +

+
+
+ +
+

8.3 Rebinding Keys

+ +

Key bindings can be changed via the following three commands in a +nanorc file: +

+
+
bind key function menu
+

Rebinds key to function in the context of menu +(or in all menus where the function exists when all is used). +

+
+
bind key "string" menu
+

Makes key produce string in the context of menu +(or in all menus where the key exists when all is used). +Besides literal text and/or control codes, the string may contain +function names between braces. These functions will be invoked when the +key is typed. To include a literal opening brace, use {{}. +

+
+
unbind key menu
+

Unbinds key from menu +(or from all menus where the key exists when all is used). +

+
+
+ +

Note that bind key "{function}" menu is equivalent to +bind key function menu, except that for the latter form +nano will check the availabilty of the function +in the given menu at startup time (and report an error if +it does not exist there), whereas for the first form nano +will check at execution time that the function exists but not +whether it makes any sense in the current menu. The user has to take +care that a function name between braces (or any sequence of them) +is appropriate. Strange behavior can result when it is not. +

+
+

The format of key should be one of: +

+
+
+
^X
+

where X is a Latin letter, or one of several +ASCII characters (@, ], \, ^, _), or the word "Space". +Example: ^C. +

+
+
M-X
+

where X is any ASCII character except [, or the word "Space". +Example: M-8. +

+
+
Sh-M-X
+

where X is a Latin letter. +Example: Sh-M-U. +By default, each Meta+letter keystroke does the same as the corresponding +Shift+Meta+letter. But when any Shift+Meta bind is made, that will +no longer be the case, for all letters. +

+
+
Fn
+

where n is a numeric value from 1 to 24. +Example: F10. +(Often, F13 to F24 can be typed as F1 to F12 +with Shift.) +

+
+
Ins or Del
+
+
+ +
+

Rebinding ^M (Enter) or ^I (Tab) is probably not a good idea. +Rebinding ^[ (Esc) is not possible, because its keycode +is the starter byte of Meta keystrokes and escape sequences. +Rebinding any of the dedicated cursor-moving keys (the arrows, Home, End, +PageUp and PageDown) is not possible. +On some terminals it’s not possible to rebind ^H (unless --raw +is used) because its keycode is identical to that of the Backspace key. +

+
+

Valid names for the function to be bound are: +

+
+
help
+

Invokes the help viewer. +

+
+
cancel
+

Cancels the current command. +

+
+
exit
+

+
+
insert
+

Inserts a file into the current buffer (at the current cursor position), +or into a new buffer when option multibuffer is set. +

+
+

+

Starts a forward search for text in the current buffer — or for filenames +matching a string in the current list in the file browser. +

+
+
wherewas
+

Starts a backward search for text in the current buffer — or for filenames +matching a string in the current list in the file browser. +

+
+
findprevious
+

Searches the next occurrence in the backward direction. +

+
+
findnext
+

Searches the next occurrence in the forward direction. +

+
+
replace
+

Interactively replaces text within the current buffer. +

+
+
cut
+

+
+
copy
+

Copies the current line (or the marked region) without deleting it. +

+
+
paste
+

Pastes the currently stored text into the current buffer at the +current cursor position. +

+
+
zap
+

Throws away the current line (or the marked region). +(This function is bound by default to Alt+Delete.) +

+
+
chopwordleft
+

Deletes from the cursor position to the beginning of the preceding word. +(This function is bound by default to Shift+Ctrl+Delete. If your terminal +produces ^H for Ctrl+Backspace, you can make Ctrl+Backspace delete +the word to the left of the cursor by rebinding ^H to this function.) +

+
+
chopwordright
+

Deletes from the cursor position to the beginning of the next word. +(This function is bound by default to Ctrl+Delete.) +

+
+
cutrestoffile
+

Cuts all text from the cursor position till the end of the buffer. +

+
+
mark
+

Sets the mark at the current position, to start selecting text. +Or, when it is set, unsets the mark. +

+
+
location
+

Reports the current position of the cursor in the buffer: +the line, column, and character positions. +

+
+
wordcount
+

Counts and reports on the status bar the number of lines, words, +and characters in the current buffer (or in the marked region). +

+
+
execute
+

Prompts for a program to execute. The program’s output will be inserted +into the current buffer (or into a new buffer when M-F is toggled). +

+
+
speller
+

Invokes a spell-checking program, either the default hunspell +or GNU spell, or the one defined by --speller or +set speller. +

+
+
formatter
+

Invokes a full-buffer-processing program (if the active syntax defines one). +(The current buffer is written out to a temporary file, the program +is run on it, and then the temporary file is read back in, replacing +the contents of the buffer.) +

+
+
linter
+

Invokes a syntax-checking program (if the active syntax defines one). +If this program produces lines of the form "filename:linenum:charnum: +some message", then the cursor will be put at the indicated position +in the mentioned file while showing "some message" on the status bar. +You can move from message to message with PgUp and PgDn, +and leave linting mode with ^C or Enter. +

+
+
justify
+

Justifies the current paragraph (or the marked region). +A paragraph is a group of contiguous lines that, apart from possibly +the first line, all have the same indentation. The beginning of a +paragraph is detected by either this lone line with a differing +indentation or by a preceding blank line. +

+
+
fulljustify

+
+
scrollup
+

Scrolls the viewport up one row (meaning that the text slides down) +while keeping the cursor in the same text position, if possible. +(This function is bound by default to Alt+Up. +If Alt+Up does nothing on your Linux console, see the FAQ: +https://nano-editor.org/dist/latest/faq.html#4.1.) +

+
+
scrolldown
+

Scrolls the viewport down one row (meaning that the text slides up) +while keeping the cursor in the same text position, if possible. +(This function is bound by default to Alt+Down.) +

9 Pico Compatibility

+ +

nano emulates Pico quite closely, but there +are some differences between the two editors: +

+
+
Hard-Wrapping
+

Unlike Pico, nano does not automatically hard-wrap the current +line when it becomes overlong during typing. This hard-wrapping can be +switched on with the --breaklonglines option. With that option, +nano by default breaks lines at screen width minus eight columns, +whereas Pico does it at screen width minus six columns. You can make +nano do as Pico by using --fill=-6. +

+
+
Scrolling
+

By default, nano will scroll just one line (instead of half +a screen) when the cursor is moved to a line that is just out of view. +And when paging up or down, nano keeps the cursor in the same +screen position as much as possible, instead of always placing it on the +first line of the viewport. The Pico-like behavior can be obtained +with the --jumpyscrolling option. +

+
+
Edit Area
+

Pico never uses the line directly below the title bar, leaving it always +blank. nano includes this line in the editing area, in order +to not waste space, and because in this way it is slightly clearer where +the text starts. If you are accustomed to this line being empty, you can +get it back with the --emptyline option. +

+
+
Interactive Replace
+

Instead of allowing you to replace either just one occurrence of a search +string or all of them, nano’s replace function is interactive: it +will pause at each found search string and query whether to replace this +instance. You can then choose Yes, or No (skip this one), or All (don’t +ask any more), or Cancel (stop with replacing). +

+
+
Search and Replace History
+

When the option -H or --historylog is given (or set in +a nanorc file), text entered as search or replace strings is stored. +These strings can be accessed with the up/down arrow keys at their +respective prompts, or you can +type the first few characters and then use Tab to cycle through the +matching strings. A retrieved string can subsequently be edited. +

+
+
Position History
+

When the option -P or --positionlog is given (or set in +a nanorc file), nano will store the position of the cursor +when you close a file, and will place the cursor in that position +again when you later reopen the file. +

+
+
Current Cursor Position
+

The output of the "Display Cursor Position" command (^C) displays +not only the current line and character position of the cursor, +but also (between the two) the current column position. +

+
+
Spell Checking
+

In the internal spell checker misspelled words are sorted alphabetically +and trimmed for uniqueness, such that the words ’apple’ and ’Apple’ will +be prompted for correction separately. +

+
+
Writing Selected Text to Files
+

When using the Write-Out key (^O), text that has been selected using the +marking key (^^) can not just be written out to a new (or existing) file, +it can also be appended or prepended to an existing file. +

+
+
Reading Text from a Command
+

When using the Read-File key (^R), nano can not just read a file, +it can also read the output of a command to be run (^X). +

+
+
Reading from Working Directory
+

By default, Pico will read files from the user’s home directory (when +using ^R), but it will write files to the current working directory +(when using ^O). nano makes this symmetrical: always reading +from and writing to the current working directory — the directory +that nano was started in. +

+
+
File Browser
+

In the file browser, nano does not implement the Add, Copy, +Rename, and Delete commands that Pico provides. In nano the +browser is just a file browser, not a file manager. +

+
+
Toggles
+

Many options which alter the functionality of the program can be +"toggled" on or off using Meta key sequences, meaning the program does +not have to be restarted to turn a particular feature on or off. +See Feature Toggles for a list of options that can be toggled. +Or see the list at the end of the main internal help text (^G) instead. +

+
+
+ + +
+

10 Building and its Options

+ +

Building nano from source is straightforward if you are +familiar with compiling programs with autoconf support: +

+
+
  tar -xf nano-x.y.tar.gz
+  cd nano-x.y
+  ./configure
+  make
+  make install
+
+ +

The possible options to ./configure are: +

+
+
--disable-browser
+

Exclude the file browser that can be called with ^T when +wanting to read or write a file. +

+
+
--disable-color
+

Exclude support for syntax coloring. This also eliminates the -Y +command-line option, which allows choosing a specific syntax. +

+
+
--disable-comment
+

Exclude the single-keystroke comment/uncomment function (M-3). +

+
+
--disable-extra
+

Exclude the Easter egg: a crawl of major contributors. +

+
+
--disable-formatter
+

Exclude the code for calling a formatting tool. +

+
+
--disable-help
+

Exclude the help texts (^G). This makes the binary much smaller, +but also makes it difficult for new users to learn more than very basic +things about using the editor. +

+
+
--disable-histories
+

Exclude the code for handling the history files: the search and +replace strings that were used, the commands that were executed, +and the cursor position at which each file was closed. +This also eliminates the -H and -P command-line +options, which switch on the storing of search/replace strings, +executed commands, and cursor positions. +

+
+
--disable-justify
+

Exclude the text-justification functions (^J and M-J). +

+
+
--disable-libmagic
+

Exclude the code for using the library of magic-number tests (for +determining the file type and thus which syntax to use for coloring — +in most cases the regexes for filename and header line will be enough). +

+
+
--disable-linenumbers
+

Exclude the ability to show line numbers. This also eliminates +the -l command-line option, which turns line numbering on. +

+
+
--disable-linter
+

Exclude the code for calling a linting tool. +

+
+
--disable-mouse
+

Exclude all mouse functionality. This also eliminates the -m +command-line option, which enables the mouse functionality. +

+
+
--disable-multibuffer
+

Exclude support for opening multiple files at a time and switching +between them. This also eliminates the -F command-line option, +which causes a file to be read into a separate buffer by default. +

+
+
--disable-nanorc
+

Exclude support for reading the nanorc files at startup. With such +support, you can store custom settings in a system-wide and a per-user +nanorc file rather than having to pass command-line options to get +the desired behavior. See Nanorc Files for more info. +Disabling this also eliminates the -I command-line option, +which inhibits the reading of nanorc files. +

+
+
--disable-operatingdir
+

Exclude the code for setting an operating directory. This also eliminates +the -o command-line option, which sets the operating directory. +

+
+
--disable-speller
+

Exclude the code for spell checking. This also eliminates the -s +command-line option, which allows specifying an alternate spell checker. +

+
+
--disable-tabcomp
+

Exclude tab completion (when nano asks for a filename or search string +or replace string or command to execute). +

+
+
--disable-wordcomp
+

Exclude word completion (^]). +

+
+
--disable-wrapping
+

Exclude all hard-wrapping of overlong lines. This also eliminates the +-b and -w command-line options, which switch automatic +long-line wrapping on and off, respectively. +

+
+
--enable-tiny
+

This option implies all of the above. It also disables some other +internals of the editor, like the function toggles, the marking of text, +the undo/redo code, line anchors, the recording and playback of a macro, +softwrapping, and the cut-to-end-of-line code. These things stay disabled +also when using the enabling counterpart of the above options together with +--enable-tiny to switch specific features back on. +

+
+
--enable-debug
+

Include some code for runtime debugging output. This can get messy, so +chances are you only want this feature when you’re working on the nano source. +

+
+
--disable-nls
+

Exclude Native Language support. This will disable the use of any +available GNU nano translations. +

+
+
--enable-utf8
+

Include support for handling and displaying Unicode files. +This requires a "wide" version of the curses library. +

+
+
--disable-utf8
+

Exclude support for handling and displaying Unicode files. Normally the +configure script auto-detects whether to enable UTF-8 support or not. +You can use this or the previous option to override that detection. +

+
+
--enable-altrcname=name
+

Use the file with the given name (in the user’s home directory) +as nano’s settings file, instead of the default .nanorc. +

Besides basic text +editing, ‘nano’ offers features like undo/redo, syntax coloring, +interactive search-and-replace, auto-indentation, line numbers, word +completion, file locking, backup files, and internationalization +support. + + The original goal for ‘nano’ was to be a complete bug-for-bug +emulation of Pico. But currently the goal is to be as compatible as is +reasonable while offering a superset of Pico’s functionality. *Note +Pico Compatibility:: for more details on how ‘nano’ and Pico differ. + + Starting with version 4.0, ‘nano’ no longer hard-wraps an overlong +line by default. It further uses linewise scrolling by default, and by +default includes the line below the title bar into the editing area. If +you want the old, Pico behavior back, you can use the following options: +‘--breaklonglines’, ‘--jumpyscrolling’, and ‘--emptyline’ (or ‘-bje’). + + Please report bugs via . + + For background information see . + + +File: nano.info, Node: Invoking, Next: Editor Basics, Prev: Introduction, Up: Top + +2 Invoking +********** + +The usual way to invoke ‘nano’ is: + + nano [FILE] + + But it is also possible to specify one or more options (*note +Command-line Options::), and to edit several files in a row. +Additionally, the cursor can be put on a specific line of a file by +adding the line number with a plus sign before the filename, and even in +a specific column by adding it with a comma. (Negative numbers count +from the end of the file or line.) The cursor can also be put on the +first or last occurrence of a specific string by specifying that string +after ‘+/’ or ‘+?’ before the filename. The string can be made case +sensitive and/or caused to be interpreted as a regular expression by +inserting a ‘c’ and/or ‘r’ after the plus sign. These search modes can +be explicitly disabled by using the uppercase variant of those letters: +‘C’ and/or ‘R’. When the string contains spaces, it needs to be +enclosed in quotes. A more complete command synopsis thus is: + + nano [OPTION]... [[+LINE[,COLUMN]|+[crCR](/|?)STRING] FILE]... + + Normally, however, you set your preferred options in a ‘nanorc’ file +(*note Nanorc Files::). And when using ‘set positionlog’ (making ‘nano’ +remember the cursor position when you close a file), you will rarely +need to specify a line number. + + As a special case: when instead of a filename a dash is given, ‘nano’ +will read data from standard input.

From top to bottom +these are: the title bar, the edit window, the status bar, and two help +lines. + + The title bar consists of three sections: left, center and right. +The section on the left displays the version of ‘nano’ being used. The +center section displays the current filename, or "New Buffer" if the +file has not yet been named. The section on the right displays +"Modified" if the file has been modified since it was last saved or +opened. + + The status bar is the third line from the bottom of the screen. It +shows important and informational messages. Any error messages that +occur from using the editor will appear on the status bar. Any +questions that are asked of the user will be asked on the status bar, +and any user input (search strings, filenames, etc.) will be input on +the status bar. + + The two help lines at the bottom of the screen show some of the most +essential functions of the editor. + + +File: nano.info, Node: Entering Text, Next: Commands, Prev: Screen Layout, Up: Editor Basics + +3.2 Entering Text +================= + +‘nano’ is a "modeless" editor. This means that all keystrokes, with the +exception of Control and Meta sequences, enter text into the file being +edited. + + Characters not present on the keyboard can be entered in two ways: + + • For characters with a single-byte code, pressing the Esc key twice + and then typing a three-digit decimal number (from ‘000’ to ‘255’) + will make ‘nano’ behave as if you typed the key with that value. + + • For any possible character, pressing ‘M-V’ (Alt+V) and then typing + a series of hexadecimal digits (at most six, or concluded with + ‘Enter’ or ‘Space’) will enter the corresponding Unicode character + into the buffer. + + For example, typing ‘Esc Esc 2 3 4’ will enter the character "ê" — +useful when writing about a French party. Typing ‘M-V 0 0 2 2 c 4’ will +enter the symbol "⋄", a little diamond. + + Typing ‘M-V’ followed by anything other than a hexadecimal digit will +enter this keystroke verbatim into the buffer, allowing the user to +insert literal control codes (except ‘^J’) or escape sequences. + + +File: nano.info, Node: Commands, Next: The Cutbuffer, Prev: Entering Text, Up: Editor Basics + +3.3 Commands +============ + +Commands are given by using the Control key (Ctrl, shown as ‘^’) or the +Meta key (Alt or Cmd, shown as ‘M-’). + + • A control-key sequence is entered by holding down the Ctrl key and + pressing the desired key. + + • A meta-key sequence is entered by holding down the Meta key + (normally the Alt key) and pressing the desired key. + + If for some reason on your system the combinations with Ctrl or Alt +do not work, you can generate them by using the Esc key. A control-key +sequence is generated by pressing the Esc key twice and then pressing +the desired key, and a meta-key sequence by pressing the Esc key once +and then pressing the desired key. + + +File: nano.info, Node: The Cutbuffer, Next: The Mark, Prev: Commands, Up: Editor Basics + +3.4 The Cutbuffer +================= + +Text can be cut from a file a whole line at a time with ‘^K’. The cut +line is stored in the cutbuffer. Consecutive strokes of ‘^K’ will add +each cut line to this buffer, but a ‘^K’ after any other keystroke will +overwrite the entire cutbuffer. + + The contents of the cutbuffer can be pasted at the current cursor +position with ‘^U’. + + A line of text can be copied into the cutbuffer (without cutting it) +with ‘M-6’. + + +File: nano.info, Node: The Mark, Next: Search and Replace, Prev: The Cutbuffer, Up: Editor Basics + +3.5 The Mark +============ + +Text can be selected by first ’setting the Mark’ with ‘^6’ or ‘M-A’ and +then moving the cursor to the other end of the portion to be selected. +The selected portion of text will be highlighted. This selection can +now be cut or copied in its entirety with a single ‘^K’ or ‘M-6’. Or +the selection can be used to limit the scope of a search-and-replace +(‘^\’) or spell-checking session (‘^T^T’). + + On some terminals, text can be selected also by holding down ‘Shift’ +while using the cursor keys. Holding down the ‘Ctrl’ or ‘Alt’ key too +will increase the stride. Such a selection is cancelled upon any cursor +movement where ‘Shift’ isn’t held. + + Cutting or copying selected text toggles off the mark automatically. +If needed, it can be toggled off manually with another ‘^6’ or ‘M-A’. + + +File: nano.info, Node: Search and Replace, Next: Using the Mouse, Prev: The Mark, Up: Editor Basics + +3.6 Search and Replace +====================== + +One can search the current buffer for the occurrence of any string with +the Search command (default key binding: ‘^W’). The default search mode +is forward, case-insensitive, and for literal strings. But one can +search backwards by pressing ‘M-B’, search case sensitively with ‘M-C’, +and interpret regular expressions in the search string with ‘M-R’. + + A regular expression in a search string always covers just one line; +it cannot span multiple lines. And when replacing (with ‘^\’ or ‘M-R’) +the replacement string cannot contain a newline (LF). + + +File: nano.info, Node: Using the Mouse, Next: Anchors, Prev: Search and Replace, Up: Editor Basics + +3.7 Using the Mouse +=================== + +When mouse support has been configured and enabled, a single mouse click +places the cursor at the indicated position. Clicking a second time in +the same position toggles the mark. Clicking in the two help lines +executes the selected shortcut. To be able to select text with the left +button, or paste text with the middle button, hold down the Shift key +during those actions. + + The mouse will work in the X Window System, and on the console when +gpm is running. + + +File: nano.info, Node: Anchors, Next: Limitations, Prev: Using the Mouse, Up: Editor Basics + +3.8 Anchors +=========== + +With ‘M-Ins’ you can place an anchor (a kind of temporary bookmark) at +the current line. With ‘M-PgUp’ and ‘M-PgDn’ you can jump to an anchor +in the backward/forward direction. This jumping wraps around at the top +and bottom. + + When a line with an anchor is removed, the line where the cursor ends +up inherits the anchor. After performing an operation on the entire +buffer (like formatting it, piping it through a command, or doing an +external spell check on it), any anchors that were present are gone. +And when you close the buffer, all its anchors simply disappear; they +are not saved. + + Anchors are visualized in the margin when line numbers are activated. + + +File: nano.info, Node: Limitations, Prev: Anchors, Up: Editor Basics + +3.9 Limitations +=============== + +The recording and playback of keyboard macros works correctly only on a +terminal emulator, not on a Linux console (VT), because the latter does +not by default distinguish modified from unmodified arrow keys. + + +File: nano.info, Node: The Help Viewer, Next: The File Browser, Prev: Editor Basics, Up: Top + +4 The Help Viewer +***************** + +The built-in help in ‘nano’ is available by pressing ‘^G’. It is fairly +self-explanatory. It documents the various parts of the editor and the +available keystrokes. Navigation is via the ‘^Y’ (Page Up) and ‘^V’ +(Page Down) keys. ‘^X’ exits from the help viewer. + + +File: nano.info, Node: The File Browser, Next: Command-line Options, Prev: The Help Viewer, Up: Top + +5 The File Browser +****************** + +When in the Read-File (‘^R’) or Write-Out menu (‘^O’), pressing ‘^T’ +will invoke the file browser. Here, one can navigate directories in a +graphical manner in order to find the desired file. + + Basic movement in the file browser is accomplished with the arrow and +other cursor-movement keys. More targeted movement is accomplished by +searching, via ‘^W’ or ‘w’, or by changing directory, via ‘^_’ or ‘g’. +The behavior of the ‘Enter’ key (or ‘s’) varies by what is currently +selected. If the currently selected object is a directory, the file +browser will enter and display the contents of the directory. If the +object is a file, this filename and path are copied to the status bar, +and the file browser exits. + + +File: nano.info, Node: Command-line Options, Next: Feature Toggles, Prev: The File Browser, Up: Top + +6 Command-line Options +********************** + +‘nano’ takes the following options from the command line: + +‘-A’ +‘--smarthome’ + Make the Home key smarter. When Home is pressed anywhere but at + the very beginning of non-whitespace characters on a line, the + cursor will jump to that beginning (either forwards or backwards). + If the cursor is already at that position, it will jump to the true + beginning of the line. + +‘-B’ +‘--backup’ + When saving a file, back up the previous version of it, using the + current filename suffixed with a tilde (‘~’). + +‘-C DIRECTORY’ +‘--backupdir=DIRECTORY’ + Make and keep not just one backup file, but make and keep a + uniquely numbered one every time a file is saved — when backups are + enabled. The uniquely numbered files are stored in the specified + directory. + +‘-D’ +‘--boldtext’ + For the interface, use bold instead of reverse video. This will be + overridden by setting the options ‘titlecolor’, ‘statuscolor’, + ‘keycolor’, ‘functioncolor’, ‘numbercolor’, and/or ‘selectedcolor’ + in your nanorc file. *Note set keycolor:: for details. + +‘-E’ +‘--tabstospaces’ + Convert each typed tab to spaces — to the number of spaces that a + tab at that position would take up. + +‘-F’ +‘--multibuffer’ + Read a file into a new buffer by default. + +‘-G’ +‘--locking’ + Enable vim-style file locking when editing files. + +‘-H’ +‘--historylog’ + Save the last hundred search strings and replacement strings and + executed commands, so they can be easily reused in later sessions. + +‘-I’ +‘--ignorercfiles’ + Don’t look at the system’s nanorc file nor at the user’s nanorc. + +‘-J’ +‘--guidestripe’ + Draw a vertical stripe at the given column, to help judge the width + of the text. (The color of the stripe can be changed with ‘set + stripecolor’ in your nanorc file.) + +‘-K’ +‘--rawsequences’ + Interpret escape sequences directly, instead of asking ‘ncurses’ to + translate them. (If you need this option to get some keys to work + properly, it means that the terminfo terminal description that is + used does not fully match the actual behavior of your terminal. + This can happen when you ssh into a BSD machine, for example.) + Using this option disables ‘nano’’s mouse support. + +‘-L’ +‘--nonewlines’ + Don’t automatically add a newline when a text does not end with + one. (This can cause you to save non-POSIX text files.) + +‘-M’ +‘--trimblanks’ + Snip trailing whitespace from the wrapped line when automatic + hard-wrapping occurs or when text is justified. + +‘-N’ +‘--noconvert’ + Disable automatic conversion of files from DOS/Mac format. + +‘-O’ +‘--bookstyle’ + When justifying, treat any line that starts with whitespace as the + beginning of a paragraph (unless auto-indenting is on). + +‘-P’ +‘--positionlog’ + For the 200 most recent files, log the last position of the cursor, + and place it at that position again upon reopening such a file. + +‘-Q "REGEX"’ +‘--quotestr="REGEX"’ + Set the regular expression for matching the quoting part of a line. + The default value is "^([ \t]*([!#%:;>|}]|//))+". (Note that ‘\t’ + stands for a literal Tab character.) This makes it possible to + rejustify blocks of quoted text when composing email, and to rewrap + blocks of line comments when writing source code. + +‘-R’ +‘--restricted’ + Restricted mode: don’t read or write to any file not specified on + the command line. This means: don’t read or write history files; + don’t allow suspending; don’t allow spell checking; don’t allow a + file to be appended to, prepended to, or saved under a different + name if it already has one; and don’t make backup files. + Restricted mode can also be activated by invoking ‘nano’ with any + name beginning with ‘r’ (e.g. ‘rnano’). + +‘-S’ +‘--softwrap’ + Display over multiple screen rows lines that exceed the screen’s + width. (You can make this soft-wrapping occur at whitespace + instead of rudely at the screen’s edge, by using also + ‘--atblanks’.)

During startup ‘nano’ will normally read +two files: first the system-wide file, ‘/etc/nanorc’ (the exact path may +be different on your system), and then the user-specific file, either +‘~/.nanorc’ or ‘$XDG_CONFIG_HOME/nano/nanorc’ or ‘.config/nano/nanorc’, +whichever exists first. However, if ‘--rcfile’ is given, ‘nano’ will +skip the above files and will read just the specified settings file. + + A nanorc file can contain ‘set’ and ‘unset’ commands for various +options (*note Settings::). It can also contain commands that define +syntax highlighting (*note Syntax Highlighting::) and commands that +rebind keys (*note Rebinding Keys::). Each command should be on a +separate line, and all commands should be written in lowercase. + + Options that do not take an argument are unset by default. So using +the ‘unset’ command is only needed when wanting to override a setting +from the system’s nanorc file in your own nanorc. Options that take an +argument cannot be unset, but can be assigned the empty string. + + Any command-line option overrides its nanorc setting, of course. + + Quotes inside the CHARACTERS parameters below should not be escaped. +The last double quote on the line will be seen as the closing quote. + +* Menu: + +* Settings:: +* Syntax Highlighting:: +* Rebinding Keys:: + + +File: nano.info, Node: Settings, Next: Syntax Highlighting, Up: Nanorc Files + +8.1 Settings +============ + +The supported settings in a nanorc file are: + +‘set afterends’ + Make ‘Ctrl+Right’ and ‘Ctrl+Delete’ stop at word ends instead of + beginnings. + +‘set allow_insecure_backup’ + When backing up files, allow the backup to succeed even if its + permissions can’t be (re)set due to special OS considerations.

This is inherently +imperfect, because regular expressions are not powerful enough to fully +parse a file. Nevertheless, regular expressions can do a lot and are +easy to make, so they are a good fit for a small editor like ‘nano’. + + See ‘/usr/share/nano/’ and ‘/usr/share/nano/extra/’ for the +syntax-coloring definitions that are available out of the box. + + All regular expressions in ‘nano’ are POSIX extended regular +expressions (ERE). This means that ‘.’, ‘?’, ‘*’, ‘+’, ‘^’, ‘$’, and +several other characters are special. The period ‘.’ matches any single +character, ‘?’ means the preceding item is optional, ‘*’ means the +preceding item may be matched zero or more times, ‘+’ means the +preceding item must be matched one or more times, ‘^’ matches the +beginning of a line, and ‘$’ the end, ‘\<’ matches the start of a word, +and ‘\>’ the end, and ‘\s’ matches a blank. It also means that +lookahead and lookbehind are not possible. A complete explanation can +be found in the manual of GNU grep: ‘info grep regular’. + + Each regular expression in a ‘nanorc’ file should be wrapped in +double quotes (‘""’). Multiple regular expressions can follow each +other on a line by separating them with blanks. This means that a +regular expression cannot contain a double quote followed by a blank. +When you need this combination inside a regular expression, then either +the double quote or the blank should be put between square brackets +(‘[]’). + + A separate syntax can be defined for each kind of file via the +following commands in a nanorc file: + +‘syntax NAME ["FILEREGEX" ...]’ + Start the definition of a syntax with this NAME. All subsequent + ‘color’ and other such commands will be added to this syntax, until + a new ‘syntax’ command is encountered. + + When ‘nano’ is run, this syntax will be automatically activated if + the current filename matches the extended regular expression + FILEREGEX. Or the syntax can be explicitly activated by using the + ‘-Y’ or ‘--syntax’ command-line option followed by the NAME. + + The ‘default’ syntax is special: it takes no FILEREGEX, and applies + to files that don’t match any syntax’s regexes. The ‘none’ syntax + is reserved; specifying it on the command line is the same as not + having a syntax at all. + +‘header "REGEX" ...’ + If from all defined syntaxes no FILEREGEX matched, then compare + this REGEX (or regexes) against the first line of the current file, + to determine whether this syntax should be used for it. + +‘magic "REGEX" ...’ + If no FILEREGEX matched and no ‘header’ regex matched either, then + compare this REGEX (or regexes) against the result of querying the + ‘magic’ database about the current file, to determine whether this + syntax should be used for it. (This functionality only works when + ‘libmagic’ is installed on the system and will be silently ignored + otherwise.) + +‘formatter PROGRAM [ARGUMENT ...]’ + Run the given PROGRAM on the full contents of the current buffer. + +‘linter PROGRAM [ARGUMENT ...]’ + Use the given PROGRAM to do a syntax check on the current buffer. + +‘comment "STRING"’ + Use the given string for commenting and uncommenting lines. If the + string contains a vertical bar or pipe character (|), this + designates bracket-style comments; for example, "/*|*/" for CSS + files. The characters before the pipe are prepended to the line + and the characters after the pipe are appended at the end of the + line. If no pipe character is present, the full string is + prepended; for example, "#" for Python files. If empty double + quotes are specified, the comment/uncomment functions are disabled; + for example, "" for JSON. The default value is "#". + +‘tabgives "STRING"’ + Make the key produce the given STRING. Useful for languages + like Python that want to see only spaces for indentation. This + overrides the setting of the ‘tabstospaces’ option. + +‘color [bold,][italic,]FGCOLOR,BGCOLOR "REGEX" ...’ + Paint all pieces of text that match the extended regular expression + "regex" with the given foreground and background colors, at least + one of which must be specified. Valid color names are: ‘red’, + ‘green’, ‘blue’, ‘magenta’, ‘yellow’, ‘cyan’, ‘white’, and ‘black’. + Each of these eight names may be prefixed with the word ‘light’ to + get a brighter version of that color. The word ‘grey’ or ‘gray’ + may be used as a synonym for ‘lightblack’. + + On terminal emulators that can do at least 256 colors, other valid + (but unprefixable) color names are: ‘pink’, ‘purple’, ‘mauve’, + ‘lagoon’, ‘mint’, ‘lime’, ‘peach’, ‘orange’, ‘latte’, ‘rosy’, + ‘beet’, ‘plum’, ‘sea’, ‘sky’, ‘slate’, ‘teal’, ‘sage’, ‘brown’, + ‘ocher’, ‘sand’, ‘tawny’, ‘brick’, ‘crimson’, and ‘normal’ — where + ‘normal’ means the default foreground or background color. On such + emulators, the color may also be specified as a three-digit + hexadecimal number prefixed with ‘#’, with the digits representing + the amounts of red, green, and blue, respectively. This tells + ‘nano’ to select from the available palette the color that + approximates the given values. + + The color pair may be preceded by ‘bold’ and/or ‘italic’ (separated + by commas) to get a bold and/or slanting typeface, if your terminal + can do those. + + All coloring commands are applied in the order in which they are + specified, which means that later commands can recolor stuff that + was colored earlier. + +‘icolor [bold,][italic,]FGCOLOR,BGCOLOR "REGEX" ...’ + Same as above, except that the matching is case insensitive. + +‘color [bold,][italic,]FGCOLOR,BGCOLOR start="FROMRX" end="TORX"’ + Paint all pieces of text whose start matches extended regular + expression "fromrx" and whose end matches extended regular + expression "torx" with the given foreground and background colors, + at least one of which must be specified. This means that, after an + initial instance of "fromrx", all text until the first instance of + "torx" will be colored. This allows syntax highlighting to span + multiple lines. + +‘icolor [bold,][italic,]FGCOLOR,BGCOLOR start="FROMRX" end="TORX"’ + Same as above, except that the matching is case insensitive. + +‘include "SYNTAXFILE"’ + Read in self-contained color syntaxes from "syntaxfile". Note that + "syntaxfile" may contain only the above commands, from ‘syntax’ to + ‘icolor’. + +‘extendsyntax NAME COMMAND ARGUMENT ...’ + Extend the syntax previously defined as "NAME" with another + COMMAND. This allows you to add a new ‘color’, ‘icolor’, ‘header’, + ‘magic’, ‘formatter’, ‘linter’, ‘comment’, or ‘tabgives’ command to + an already defined syntax — useful when you want to slightly + improve a syntax defined in one of the system-installed files + (which normally are not writable). + + +File: nano.info, Node: Rebinding Keys, Prev: Syntax Highlighting, Up: Nanorc Files + +8.3 Rebinding Keys +================== + +Key bindings can be changed via the following three commands in a nanorc +file: + +‘bind key function menu’ + Rebinds ‘key’ to ‘function’ in the context of ‘menu’ (or in all + menus where the function exists when ‘all’ is used). + +‘bind key "string" menu’ + Makes ‘key’ produce ‘string’ in the context of ‘menu’ (or in all + menus where the key exists when ‘all’ is used). Besides literal + text and/or control codes, the ‘string’ may contain function names + between braces. These functions will be invoked when the key is + typed. To include a literal opening brace, use ‘{{}’. + +‘unbind key menu’ + Unbinds ‘key’ from ‘menu’ (or from all menus where the key exists + when ‘all’ is used). + + Note that ‘bind key "{function}" menu’ is equivalent to ‘bind key +function menu’, except that for the latter form ‘nano’ will check the +availabilty of the ‘function’ in the given ‘menu’ at startup time (and +report an error if it does not exist there), whereas for the first form +‘nano’ will check at execution time that the ‘function’ exists but not +whether it makes any sense in the current menu. The user has to take +care that a function name between braces (or any sequence of them) is +appropriate. Strange behavior can result when it is not. + + + The format of ‘key’ should be one of: + + ‘^X’ + where X is a Latin letter, or one of several ASCII characters + (@, ], \, ^, _), or the word "Space". Example: ‘^C’. + + ‘M-X’ + where X is any ASCII character except [, or the word "Space". + Example: ‘M-8’. + + ‘Sh-M-X’ + where X is a Latin letter. Example: ‘Sh-M-U’. By default, + each Meta+letter keystroke does the same as the corresponding + Shift+Meta+letter. But when any Shift+Meta bind is made, that + will no longer be the case, for all letters. + + ‘FN’ + where N is a numeric value from 1 to 24. Example: ‘F10’. + (Often, ‘F13’ to ‘F24’ can be typed as ‘F1’ to ‘F12’ with + Shift.) + + ‘Ins’ or ‘Del’ + + + Rebinding ‘^M’ (Enter) or ‘^I’ (Tab) is probably not a good idea. +Rebinding ‘^[’ (Esc) is not possible, because its keycode is the starter +byte of Meta keystrokes and escape sequences. Rebinding any of the +dedicated cursor-moving keys (the arrows, Home, End, PageUp and +PageDown) is not possible. On some terminals it’s not possible to +rebind ‘^H’ (unless ‘--raw’ is used) because its keycode is identical to +that of the Backspace key. + + + Valid names for the ‘function’ to be bound are: + +‘help’ + Invokes the help viewer. + +‘cancel’ + Cancels the current command. + +‘exit’ + Exits from the program (or from the help viewer or file browser). + +‘writeout’ + Writes the current buffer to disk, asking for a name. + +‘savefile’ + Writes the current file to disk without prompting. + +‘insert’ + Inserts a file into the current buffer (at the current cursor + position), or into a new buffer when option ‘multibuffer’ is set. + +‘whereis’ + Starts a forward search for text in the current buffer — or for + filenames matching a string in the current list in the file + browser. + +‘wherewas’ + Starts a backward search for text in the current buffer — or for + filenames matching a string in the current list in the file + browser. + +‘findprevious’ + Searches the next occurrence in the backward direction. + +‘findnext’ + Searches the next occurrence in the forward direction. + +‘replace’ + Interactively replaces text within the current buffer. + +‘cut’ + Cuts and stores the current line (or the marked region). + +‘copy’ + Copies the current line (or the marked region) without deleting it. + +‘paste’ + Pastes the currently stored text into the current buffer at the + current cursor position. + +‘zap’ + Throws away the current line (or the marked region). (This + function is bound by default to ‘Alt+Delete’.) + +‘chopwordleft’ + Deletes from the cursor position to the beginning of the preceding + word. (This function is bound by default to ‘Shift+Ctrl+Delete’. + If your terminal produces ‘^H’ for ‘Ctrl+Backspace’, you can make + ‘Ctrl+Backspace’ delete the word to the left of the cursor by + rebinding ‘^H’ to this function.) + +‘chopwordright’ + Deletes from the cursor position to the beginning of the next word. + (This function is bound by default to ‘Ctrl+Delete’.) + +‘cutrestoffile’ + Cuts all text from the cursor position till the end of the buffer. + +‘mark’ + Sets the mark at the current position, to start selecting text. + Or, when it is set, unsets the mark. + +‘location’ + Reports the current position of the cursor in the buffer: the line, + column, and character positions. + +‘wordcount’ + Counts and reports on the status bar the number of lines, words, + and characters in the current buffer (or in the marked region). + +‘execute’ + Prompts for a program to execute. The program’s output will be + inserted into the current buffer (or into a new buffer when ‘M-F’ + is toggled). + +‘speller’ + Invokes a spell-checking program, either the default ‘hunspell’ or + GNU ‘spell’, or the one defined by ‘--speller’ or ‘set speller’. + +‘formatter’ + Invokes a full-buffer-processing program (if the active syntax + defines one). (The current buffer is written out to a temporary + file, the program is run on it, and then the temporary file is read + back in, replacing the contents of the buffer.) + +‘linter’ + Invokes a syntax-checking program (if the active syntax defines + one). If this program produces lines of the form + "filename:linenum:charnum: some message", then the cursor will be + put at the indicated position in the mentioned file while showing + "some message" on the status bar. You can move from message to + message with ‘PgUp’ and ‘PgDn’, and leave linting mode with ‘^C’ or + ‘Enter’. + +‘justify’ + Justifies the current paragraph (or the marked region). A + paragraph is a group of contiguous lines that, apart from possibly + the first line, all have the same indentation. The beginning of a + paragraph is detected by either this lone line with a differing + indentation or by a preceding blank line. + +‘fulljustify’ + Justifies the entire current buffer (or the marked region). + +‘indent’ + Indents (shifts to the right) the current line or the marked lines. + +‘unindent’ + Unindents (shifts to the left) the current line or the marked + lines. + +‘comment’ + Comments or uncomments the current line or the marked lines, using + the comment style specified in the active syntax. + +‘complete’ + Completes (when possible) the fragment before the cursor to a full + word found elsewhere in the current buffer. + +‘left’ + Goes left one position (in the editor or browser). + +‘right’ + Goes right one position (in the editor or browser). + +‘up’ + Goes one line up (in the editor or browser). + +‘down’ + Goes one line down (in the editor or browser). + +‘scrollup’ + Scrolls the viewport up one row (meaning that the text slides down) + while keeping the cursor in the same text position, if possible. + (This function is bound by default to ‘Alt+Up’. If ‘Alt+Up’ does + nothing on your Linux console, see the FAQ: + .) + +‘scrolldown’ + Scrolls the viewport down one row (meaning that the text slides up) + while keeping the cursor in the same text position, if possible. + (This function is bound by default to ‘Alt+Down’.) + +‘center’ + Scrolls the line with the cursor to the middle of the screen. + +‘prevword’ + Moves the cursor to the beginning of the previous word. + +‘nextword’ + Moves the cursor to the beginning of the next word. + +‘home’ + Moves the cursor to the beginning of the current line. + +‘end’ + Moves the cursor to the end of the current line. + +‘beginpara’ + Moves the cursor to the beginning of the current paragraph. + +‘endpara’ + Moves the cursor to the end of the current paragraph. + +‘prevblock’ + Moves the cursor to the beginning of the current or preceding block + of text. (Blocks are separated by one or more blank lines.) + +‘nextblock’ + Moves the cursor to the beginning of the next block of text. + +‘pageup’ + Goes up one screenful. + +‘pagedown’ + Goes down one screenful. + +‘firstline’ + Goes to the first line of the file. + +‘lastline’ + Goes to the last line of the file. + +‘gotoline’ + Goes to a specific line (and column if specified). Negative + numbers count from the end of the file (and end of the line). + +‘findbracket’ + Moves the cursor to the bracket (or brace or parenthesis, etc.) + that matches (pairs) with the one under the cursor. *Note set + matchbrackets::. + +‘anchor’ + Places an anchor at the current line, or removes it when already + present. (An anchor is visible when line numbers are activated.) + +‘prevanchor’ + Goes to the first anchor before the current line. + +‘nextanchor’ + Goes to the first anchor after the current line. + +‘prevbuf’ + Switches to editing/viewing the previous buffer when multiple + buffers are open. + +‘nextbuf’ + Switches to editing/viewing the next buffer when multiple buffers + are open. + +‘verbatim’ + Inserts the next keystroke verbatim into the file, or begins + Unicode input when a hexadecimal digit is typed (*note Entering + Text:: for details). + +‘tab’ + Inserts a tab at the current cursor location. + +‘enter’ + Inserts a new line below the current one. + +‘delete’ + Deletes the character under the cursor. + +‘backspace’ + Deletes the character before the cursor. + +‘recordmacro’ + Starts the recording of keystrokes — the keystrokes are stored as a + macro. When already recording, the recording is stopped. + +‘runmacro’ + Replays the keystrokes of the last recorded macro. + +‘undo’ + Undoes the last performed text action (add text, delete text, etc). + +‘redo’ + Redoes the last undone action (i.e., it undoes an undo). + +‘refresh’ + Refreshes the screen. + +‘suspend’ + Suspends the editor and returns control to the shell (until you + tell the process to resume execution with ‘fg’). + +‘casesens’ + Toggles whether searching/replacing ignores or respects the case of + the given characters. + +‘regexp’ + Toggles whether searching/replacing uses literal strings or regular + expressions. + +‘backwards’ + Toggles whether searching/replacing goes forward or backward. + +‘older’ + Retrieves the previous (earlier) entry at a prompt. + +‘newer’ + Retrieves the next (later) entry at a prompt. + +‘flipreplace’ + Toggles between searching for something and replacing something. + +‘flipgoto’ + Toggles between searching for text and targeting a line number. + +‘flipexecute’ + Toggles between inserting a file and executing a command. + +‘flippipe’ + When executing a command, toggles whether the current buffer (or + marked region) is piped to the command. + +‘flipnewbuffer’ + Toggles between inserting into the current buffer and into a new + empty buffer. + +‘flipconvert’ + When reading in a file, toggles between converting and not + converting it from DOS/Mac format. Converting is the default. + +‘dosformat’ + When writing a file, switches to writing a DOS format (CR/LF). + +‘macformat’ + When writing a file, switches to writing a Mac format. + +‘append’ + When writing a file, appends to the end instead of overwriting. + +‘prepend’ + When writing a file, ’prepends’ (writes at the beginning) instead + of overwriting. + +‘backup’ + When writing a file, creates a backup of the current file. + +‘discardbuffer’ + When about to write a file, discard the current buffer without + saving. (This function is bound by default only when option + ‘--saveonexit’ is in effect.) + +‘browser’ + Starts the file browser (in the Read File and Write Out menus), + allowing to select a file from a list. + +‘gotodir’ + Goes to a directory to be specified, allowing to browse anywhere in + the filesystem. + +‘firstfile’ + Goes to the first file in the list when using the file browser. + +‘lastfile’ + Goes to the last file in the list when using the file browser. + +‘nohelp’ + Toggles the presence of the two-line list of key bindings at the + bottom of the screen. (This toggle is special: it is available in + all menus except the help viewer and the linter. All further + toggles are available in the main menu only.) + +‘zero’ + Toggles the presence of title bar and status bar. + +‘constantshow’ + Toggles the constant display of the current line, column, and + character positions. + +‘softwrap’ + Toggles the displaying of overlong lines on multiple screen lines. + +‘linenumbers’ + Toggles the display of line numbers in front of the text. + +‘whitespacedisplay’ + Toggles the showing of whitespace. + +‘nosyntax’ + Toggles syntax highlighting. + +‘smarthome’ + Toggles the smartness of the Home key. + +‘autoindent’ + Toggles whether a newly created line will contain the same amount + of leading whitespace as the preceding line — or as the next line + if the preceding line is the beginning of a paragraph. + +‘cutfromcursor’ + Toggles whether cutting text will cut the whole line or just from + the current cursor position to the end of the line. + +‘breaklonglines’ + Toggles whether long lines will be hard-wrapped to the next line. + (The old name of this function, ’nowrap’, is deprecated.) + +‘tabstospaces’ + Toggles whether typed tabs will be converted to spaces. + +‘mouse’ + Toggles mouse support. + + + Valid names for ‘menu’ are: + +‘main’ + The main editor window where text is entered and edited. + +‘help’ + The help-viewer menu. + +‘search’ + The search menu (AKA whereis). + +‘replace’ + The ’search to replace’ menu. + +‘replacewith’ + The ’replace with’ menu, which comes up after ’search to replace’. + +‘yesno’ + The ’yesno’ menu, where the Yes/No/All/Cancel question is asked. + +‘gotoline’ + The ’goto line (and column)’ menu. + +‘writeout’ + The ’write file’ menu. + +‘insert’ + The ’insert file’ menu. + +‘browser’ + The ’file browser’ menu, for selecting a file to be opened or + inserted or written to. + +‘whereisfile’ + The ’search for a file’ menu in the file browser. + +‘gotodir’ + The ’go to directory’ menu in the file browser. + +‘execute’ + The menu for inserting the output from an external command, or for + filtering the buffer (or the marked region) through an external + command, or for executing one of several tools. + +‘spell’ + The menu of the integrated spell checker where the user can edit a + misspelled word. + +‘linter’ + The linter menu, which allows jumping through the linting messages. + +‘all’ + A special name that encompasses all menus. For ‘bind’ it means all + menus where the specified ‘function’ exists; for ‘unbind’ it means + all menus where the specified ‘key’ exists. + + +File: nano.info, Node: Pico Compatibility, Next: Building and its Options, Prev: Nanorc Files, Up: Top + +9 Pico Compatibility +******************** + +‘nano’ emulates Pico quite closely, but there are some differences +between the two editors: + +‘Hard-Wrapping’ + Unlike Pico, ‘nano’ does not automatically hard-wrap the current + line when it becomes overlong during typing. This hard-wrapping + can be switched on with the ‘--breaklonglines’ option. With that + option, ‘nano’ by default breaks lines at screen width minus eight + columns, whereas Pico does it at screen width minus six columns. + You can make ‘nano’ do as Pico by using ‘--fill=-6’. + +‘Scrolling’ + By default, ‘nano’ will scroll just one line (instead of half a + screen) when the cursor is moved to a line that is just out of + view. And when paging up or down, ‘nano’ keeps the cursor in the + same screen position as much as possible, instead of always placing + it on the first line of the viewport. The Pico-like behavior can + be obtained with the ‘--jumpyscrolling’ option. + +‘Edit Area’ + Pico never uses the line directly below the title bar, leaving it + always blank. ‘nano’ includes this line in the editing area, in + order to not waste space, and because in this way it is slightly + clearer where the text starts. If you are accustomed to this line + being empty, you can get it back with the ‘--emptyline’ option. + +‘Interactive Replace’ + Instead of allowing you to replace either just one occurrence of a + search string or all of them, ‘nano’’s replace function is + interactive: it will pause at each found search string and query + whether to replace this instance. You can then choose Yes, or No + (skip this one), or All (don’t ask any more), or Cancel (stop with + replacing). + +‘Search and Replace History’ + When the option ‘-H’ or ‘--historylog’ is given (or set in a nanorc + file), text entered as search or replace strings is stored. These + strings can be accessed with the up/down arrow keys at their + respective prompts, or you can type the first few characters and + then use ‘Tab’ to cycle through the matching strings. A retrieved + string can subsequently be edited. + +‘Position History’ + When the option ‘-P’ or ‘--positionlog’ is given (or set in a + nanorc file), ‘nano’ will store the position of the cursor when you + close a file, and will place the cursor in that position again when + you later reopen the file. + +‘Current Cursor Position’ + The output of the "Display Cursor Position" command (‘^C’) displays + not only the current line and character position of the cursor, but + also (between the two) the current column position. + +‘Spell Checking’ + In the internal spell checker misspelled words are sorted + alphabetically and trimmed for uniqueness, such that the words + ’apple’ and ’Apple’ will be prompted for correction separately. + +‘Writing Selected Text to Files’ + When using the Write-Out key (‘^O’), text that has been selected + using the marking key (‘^^’) can not just be written out to a new + (or existing) file, it can also be appended or prepended to an + existing file. + +‘Reading Text from a Command’ + When using the Read-File key (‘^R’), ‘nano’ can not just read a + file, it can also read the output of a command to be run (‘^X’). + +‘Reading from Working Directory’ + By default, Pico will read files from the user’s home directory + (when using ‘^R’), but it will write files to the current working + directory (when using ‘^O’). ‘nano’ makes this symmetrical: always + reading from and writing to the current working directory — the + directory that ‘nano’ was started in. + +‘File Browser’ + In the file browser, ‘nano’ does not implement the Add, Copy, + Rename, and Delete commands that Pico provides. In ‘nano’ the + browser is just a file browser, not a file manager. + +‘Toggles’ + Many options which alter the functionality of the program can be + "toggled" on or off using Meta key sequences, meaning the program + does not have to be restarted to turn a particular feature on or + off. *Note Feature Toggles:: for a list of options that can be + toggled. Or see the list at the end of the main internal help text + (‘^G’) instead. + + +File: nano.info, Node: Building and its Options, Prev: Pico Compatibility, Up: Top + +10 Building and its Options +*************************** + +Building ‘nano’ from source is straightforward if you are familiar with +compiling programs with autoconf support: + + tar -xf nano-x.y.tar.gz + cd nano-x.y + ./configure + make + make install + + The possible options to ‘./configure’ are: + +‘--disable-browser’ + Exclude the file browser that can be called with ‘^T’ when wanting + to read or write a file. + +‘--disable-color’ + Exclude support for syntax coloring. This also eliminates the ‘-Y’ + command-line option, which allows choosing a specific syntax. + +‘--disable-comment’ + Exclude the single-keystroke comment/uncomment function (‘M-3’). + +‘--disable-extra’ + Exclude the Easter egg: a crawl of major contributors. + +‘--disable-formatter’ + Exclude the code for calling a formatting tool. + +‘--disable-help’ + Exclude the help texts (‘^G’). This makes the binary much smaller, + but also makes it difficult for new users to learn more than very + basic things about using the editor. + +‘--disable-histories’ + Exclude the code for handling the history files: the search and + replace strings that were used, the commands that were executed, + and the cursor position at which each file was closed. This also + eliminates the ‘-H’ and ‘-P’ command-line options, which switch on + the storing of search/replace strings, executed commands, and + cursor positions. + +‘--disable-justify’ + Exclude the text-justification functions (‘^J’ and ‘M-J’). + +‘--disable-libmagic’ + Exclude the code for using the library of magic-number tests (for + determining the file type and thus which syntax to use for coloring + — in most cases the regexes for filename and header line will be + enough). + +‘--disable-linenumbers’ + Exclude the ability to show line numbers. This also eliminates the + ‘-l’ command-line option, which turns line numbering on. + +‘--disable-linter’ + Exclude the code for calling a linting tool. + +‘--disable-mouse’ + Exclude all mouse functionality. This also eliminates the ‘-m’ + command-line option, which enables the mouse functionality. + +‘--disable-multibuffer’ + Exclude support for opening multiple files at a time and switching + between them. This also eliminates the ‘-F’ command-line option, + which causes a file to be read into a separate buffer by default. + +‘--disable-nanorc’ + Exclude support for reading the nanorc files at startup. With such + support, you can store custom settings in a system-wide and a + per-user nanorc file rather than having to pass command-line + options to get the desired behavior. *Note Nanorc Files:: for more + info. Disabling this also eliminates the ‘-I’ command-line option, + which inhibits the reading of nanorc files. + +‘--disable-operatingdir’ + Exclude the code for setting an operating directory. This also + eliminates the ‘-o’ command-line option, which sets the operating + directory. + +‘--disable-speller’ + Exclude the code for spell checking. This also eliminates the ‘-s’ + command-line option, which allows specifying an alternate spell + checker. + +‘--disable-tabcomp’ + Exclude tab completion (when nano asks for a filename or search + string or replace string or command to execute). + +‘--disable-wordcomp’ + Exclude word completion (‘^]’). + +‘--disable-wrapping’ + Exclude all hard-wrapping of overlong lines. This also eliminates + the ‘-b’ and ‘-w’ command-line options, which switch automatic + long-line wrapping on and off, respectively. + +‘--enable-tiny’ + This option implies all of the above. It also disables some other + internals of the editor, like the function toggles, the marking of + text, the undo/redo code, line anchors, the recording and playback + of a macro, softwrapping, and the cut-to-end-of-line code. These + things stay disabled also when using the enabling counterpart of + the above options together with ‘--enable-tiny’ to switch specific + features back on. + +‘--enable-debug’ + Include some code for runtime debugging output. This can get + messy, so chances are you only want this feature when you’re + working on the nano source. + +‘--disable-nls’ + Exclude Native Language support. This will disable the use of any + available GNU ‘nano’ translations. + +‘--enable-utf8’ + Include support for handling and displaying Unicode files. This + requires a "wide" version of the curses library. + +‘--disable-utf8’ + Exclude support for handling and displaying Unicode files. + Normally the configure script auto-detects whether to enable UTF-8 + support or not. You can use this or the previous option to + override that detection. + +‘--enable-altrcname=NAME’ + Use the file with the given NAME (in the user’s home directory) as + nano’s settings file, instead of the default ‘.nanorc’. + + + +Tag Table: +Node: Top199 +Node: Introduction579 +Node: Invoking1775 +Node: Editor Basics3391 +Node: Screen Layout3677 +Node: Entering Text4779 +Node: Commands6034 +Node: The Cutbuffer6831 +Node: The Mark7405 +Node: Search and Replace8382 +Node: Using the Mouse9112 +Node: Anchors9726 +Node: Limitations10531 +Node: The Help Viewer10848 +Node: The File Browser11272 +Node: Command-line Options12170 +Ref: --speller21707 +Node: Feature Toggles25939 +Node: Nanorc Files28010 +Node: Settings29575 +Ref: set keycolor33747 +Ref: set matchbrackets35825 +Ref: Whitespace44200 +Node: Syntax Highlighting45378 +Node: Rebinding Keys52989 +Node: Pico Compatibility68936 +Node: Building and its Options73495 + +End Tag Table + + +Local Variables: +coding: utf-8 +End: diff --git a/doc/nano.texi b/doc/nano.texi new file mode 100644 index 0000000..f5817d6 --- /dev/null +++ b/doc/nano.texi @@ -0,0 +1,2082 @@ +\input texinfo + +@c %**start of header +@setfilename nano.info +@settitle The GNU nano text editor +@c %**end of header + +@documentencoding UTF-8 + +@documentdescription +The complete manual for the GNU nano text editor. +@end documentdescription + +@smallbook +@set EDITION 0.7 +@set VERSION 7.2 +@set UPDATED January 2023 + +@dircategory Editors +@direntry +* nano: (nano).

Besides +basic text editing, @command{nano} offers features like undo/redo, +syntax coloring, interactive search-and-replace, auto-indentation, +line numbers, word completion, file locking, backup files, and +internationalization support. + +The original goal for @command{nano} was to be a complete bug-for-bug +emulation of Pico. But currently the goal is to be as compatible +as is reasonable while offering a superset of Pico's functionality. +@xref{Pico Compatibility} for more details on how @command{nano} and +Pico differ. + +Starting with version 4.0, @command{nano} no longer hard-wraps an overlong +line by default. It further uses linewise scrolling by default, and by +default includes the line below the title bar into the editing area. +If you want the old, Pico behavior back, you can use the +following options: @option{--breaklonglines}, +@option{--jumpyscrolling}, and @option{--emptyline} +(or @option{-bje}). + +@blankline +Please report bugs via @url{https://savannah.gnu.org/bugs/?group=nano}. + +@blankline +For background information see @url{https://nano-editor.org/}. + + +@node Invoking +@chapter Invoking + +The usual way to invoke @command{nano} is: + +@blankline +@example +@code{nano [FILE]} +@end example +@blankline + +But it is also possible to specify one or more options (@pxref{Command-line Options}), +and to edit several files in a row. Additionally, the cursor +can be put on a specific line of a file by adding the line number +with a plus sign before the filename, and even in a specific column by +adding it with a comma. +(Negative numbers count from the end of the file or line.) +The cursor can also be put on the first or last occurrence of a specific string +by specifying that string after @code{+/} or @code{+?} before the filename. +The string can be made case sensitive and/or caused to be interpreted as a +regular expression by inserting a @code{c} and/or @code{r} after the plus sign. +These search modes can be explicitly disabled by using the uppercase variant +of those letters: @code{C} and/or @code{R}. When the string contains spaces, +it needs to be enclosed in quotes. +A more complete command synopsis thus is: + +@blankline +@example +@code{nano [OPTION]@dots{} [[+LINE[,COLUMN]|+[crCR](/|?)STRING] FILE]@dots{}} +@end example +@blankline + +Normally, however, you set your preferred options in a @file{nanorc} +file (@pxref{Nanorc Files}). And when using @code{set positionlog} +(making @command{nano} remember the cursor position when you close a file), +you will rarely need to specify a line number. + +As a special case: when instead of a filename a dash is given, @command{nano} +will read data from standard input. This means you can pipe the output of +a command straight into a buffer, and then edit it. + + +@node Editor Basics +@chapter Editor Basics + +@menu +* Screen Layout:: +* Entering Text:: +* Commands:: +* The Cutbuffer:: +* The Mark:: +* Search and Replace:: +* Using the Mouse:: +* Anchors:: +* Limitations:: +@end menu + +@node Screen Layout +@section Screen Layout + +The default screen of @command{nano} consists of four areas. +From top to bottom these are: the title bar, the edit window, +the status bar, and two help lines. + +The title bar consists of +three sections: left, center and right. The section on the left +displays the version of @command{nano} being used. The center section +displays the current filename, or "New Buffer" if the file has not yet +been named. The section on the right displays "Modified" if the +file has been modified since it was last saved or opened. + +The status bar is the third line from the bottom of the screen. It +shows important and informational messages. Any error messages that +occur from using the editor will appear on the status bar. Any questions +that are asked of the user will be asked on the status bar, and any user +input (search strings, filenames, etc.) will be input on the status bar. + +The two help lines at the bottom of the screen show some of the most +essential functions of the editor. + +@node Entering Text +@section Entering Text + +@command{nano} is a "modeless" editor. This means that all keystrokes, +with the exception of Control and Meta sequences, enter text into the +file being edited. + +Characters not present on the keyboard can be entered in two ways: + +@itemize @bullet +@item +For characters with a single-byte code, +pressing the Esc key twice and then typing a three-digit decimal number +(from @kbd{000} to @kbd{255}) will make @command{nano} behave as if you +typed the key with that value. + +@item +For any possible character, pressing @kbd{M-V} (Alt+V) and then typing a +series of hexadecimal digits (at most six, or concluded with @kbd{Enter} or +@kbd{Space}) will enter the corresponding Unicode character into the buffer. +@end itemize + +For example, typing @kbd{Esc Esc 2 3 4} will enter the character "ê" --- +useful when writing about a French party. Typing @kbd{M-V 0 0 2 2 c 4} +will enter the symbol "⋄", a little diamond. + +Typing @kbd{M-V} followed by anything other than a hexadecimal digit +will enter this keystroke verbatim into the buffer, allowing the user +to insert literal control codes (except @code{^J}) or escape sequences. + +@node Commands +@section Commands + +Commands are given by using the Control key (Ctrl, shown as @kbd{^}) +or the Meta key (Alt or Cmd, shown as @kbd{M-}). + +@itemize @bullet +@item +A control-key sequence is entered by holding down the Ctrl key and +pressing the desired key. + +@item +A meta-key sequence is entered by holding down the Meta key (normally +the Alt key) and pressing the desired key. +@end itemize + +If for some reason on your system the combinations with Ctrl or Alt do +not work, you can generate them by using the Esc key. A control-key +sequence is generated by pressing the Esc key twice and then pressing +the desired key, and a meta-key sequence by pressing the Esc key once +and then pressing the desired key. + +@node The Cutbuffer +@section The Cutbuffer + +Text can be cut from a file a whole line at a time with @kbd{^K}. +The cut line is stored in the cutbuffer. Consecutive strokes of @kbd{^K} +will add each cut line to this buffer, but a @kbd{^K} +after any other keystroke will overwrite the entire cutbuffer. + +The contents of the cutbuffer can be pasted at the current cursor position +with @kbd{^U}. + +A line of text can be copied into the cutbuffer (without cutting it) +with @kbd{M-6}. + +@node The Mark +@section The Mark + +Text can be selected by first 'setting the Mark' with @kbd{^6} +or @kbd{M-A} and then moving the cursor to the other end of the portion +to be selected. The selected portion of text will be highlighted. +This selection can now be cut or copied in its entirety with a single +@kbd{^K} or @kbd{M-6}. Or the selection can be used to limit the scope of +a search-and-replace (@kbd{^\}) or spell-checking session (@kbd{^T^T}). + +On some terminals, text can be selected also by holding down @kbd{Shift} +while using the cursor keys. Holding down the @kbd{Ctrl} or @kbd{Alt} +key too will increase the stride. Such a selection is cancelled +upon any cursor movement where @kbd{Shift} isn't held. + +Cutting or copying selected text toggles off the mark automatically. +If needed, it can be toggled off manually with another @kbd{^6} or @kbd{M-A}. + +@node Search and Replace +@section Search and Replace + +One can search the current buffer for the occurrence of any string +with the Search command (default key binding: @kbd{^W}). The default search +mode is forward, case-insensitive, and for literal strings. But one +can search backwards by pressing @kbd{M-B}, search case sensitively with @kbd{M-C}, +and interpret regular expressions in the search string with @kbd{M-R}. + +A regular expression in a search string always covers just one line; +it cannot span multiple lines. And when replacing (with @kbd{^\} or @kbd{M-R}) +the replacement string cannot contain a newline (LF). + +@node Using the Mouse +@section Using the Mouse + +When mouse support has been configured and enabled, a single mouse click +places the cursor at the indicated position. Clicking a second time in +the same position toggles the mark. Clicking in the two help lines +executes the selected shortcut. To be able to select text with the +left button, or paste text with the middle button, hold down the +Shift key during those actions. + +The mouse will work in the X Window System, and on the console when gpm +is running. + +@node Anchors +@section Anchors + +With @kbd{M-Ins} you can place an anchor (a kind of temporary bookmark) +at the current line. With @kbd{M-PgUp} and @kbd{M-PgDn} you can jump +to an anchor in the backward/forward direction. This jumping wraps +around at the top and bottom. + +When a line with an anchor is removed, the line where the cursor ends up +inherits the anchor. After performing an operation on the entire buffer +(like formatting it, piping it through a command, or doing an external +spell check on it), any anchors that were present are gone. And when +you close the buffer, all its anchors simply disappear; they are not saved. + +Anchors are visualized in the margin when line numbers are activated. + +@node Limitations +@section Limitations + +The recording and playback of keyboard macros works correctly only on a +terminal emulator, not on a Linux console (VT), because the latter does +not by default distinguish modified from unmodified arrow keys. + + +@node The Help Viewer +@chapter The Help Viewer + +The built-in help in @command{nano} is available by pressing @kbd{^G}. +It is fairly self-explanatory. It documents the various parts of the +editor and the available keystrokes. Navigation is via the @kbd{^Y} (Page Up) +and @kbd{^V} (Page Down) keys. @kbd{^X} exits from the help viewer. + + +@node The File Browser +@chapter The File Browser + +When in the Read-File (@kbd{^R}) or Write-Out menu (@kbd{^O}), +pressing @kbd{^T} will invoke the file browser. +Here, one can navigate directories in a graphical manner in order to +find the desired file. + +Basic movement in the file browser is accomplished with the arrow and +other cursor-movement keys. More targeted movement is accomplished by +searching, via @kbd{^W} or @kbd{w}, or by changing directory, via +@kbd{^_} or @kbd{g}. The behavior of the @kbd{Enter} key (or @kbd{s}) +varies by what is currently selected. +If the currently selected object is a directory, the file browser will +enter and display the contents of the directory. If the object is a +file, this filename and path are copied to the status bar, and the file +browser exits. + + +@node Command-line Options +@chapter Command-line Options + +@command{nano} takes the following options from the command line: + +@table @option + +@item -A +@itemx --smarthome +Make the Home key smarter. When Home is pressed anywhere but at the +very beginning of non-whitespace characters on a line, the cursor will +jump to that beginning (either forwards or backwards). If the cursor is +already at that position, it will jump to the true beginning of the +line. + +@item -B +@itemx --backup +When saving a file, back up the previous version of it, using the current +filename suffixed with a tilde (@code{~}). + +@item -C @var{directory} +@itemx --backupdir=@var{directory} +Make and keep not just one backup file, but make and keep a uniquely +numbered one every time a file is saved --- when backups are enabled. +The uniquely numbered files are stored in the specified directory. + +@item -D +@itemx --boldtext +For the interface, use bold instead of reverse video. This will be overridden +by setting the options @code{titlecolor}, @code{statuscolor}, @code{keycolor}, +@code{functioncolor}, @code{numbercolor}, and/or @code{selectedcolor} in your +nanorc file. @xref{@code{set keycolor}} for details. + +@item -E +@itemx --tabstospaces +Convert each typed tab to spaces --- to the number of spaces +that a tab at that position would take up. + +@item -F +@itemx --multibuffer +Read a file into a new buffer by default. + +@item -G +@itemx --locking +Enable vim-style file locking when editing files. + +@item -H +@itemx --historylog +Save the last hundred search strings and replacement strings and +executed commands, so they can be easily reused in later sessions. + +@item -I +@itemx --ignorercfiles +Don't look at the system's nanorc file nor at the user's nanorc. + +@item -J +@itemx --guidestripe +Draw a vertical stripe at the given column, to help judge the width of the +text. (The color of the stripe can be changed with @code{set stripecolor} +in your nanorc file.) + +@item -K +@itemx --rawsequences +Interpret escape sequences directly, instead of asking @code{ncurses} +to translate them. (If you need this option to get some keys to work +properly, it means that the terminfo terminal description that is used +does not fully match the actual behavior of your terminal. This can +happen when you ssh into a BSD machine, for example.) +Using this option disables @command{nano}'s mouse support. + +@item -L +@itemx --nonewlines +Don't automatically add a newline when a text does not end with one. +(This can cause you to save non-POSIX text files.) + +@item -M +@itemx --trimblanks +Snip trailing whitespace from the wrapped line when automatic +hard-wrapping occurs or when text is justified. + +@item -N +@itemx --noconvert +Disable automatic conversion of files from DOS/Mac format. + +@item -O +@itemx --bookstyle +When justifying, treat any line that starts with whitespace as the +beginning of a paragraph (unless auto-indenting is on). + +@item -P +@itemx --positionlog +For the 200 most recent files, log the last position of the cursor, +and place it at that position again upon reopening such a file. + +@item -Q "@var{regex}" +@itemx --quotestr="@var{regex}" +Set the regular expression for matching the quoting part of a line. +The default value is "@t{^([@w{ }\t]*([!#%:;>|@}]|//))+}". +(Note that @code{\t} stands for a literal Tab character.) +This makes it possible to rejustify blocks of quoted text when composing +email, and to rewrap blocks of line comments when writing source code. + +@item -R +@itemx --restricted +Restricted mode: don't read or write to any file not specified on the +command line. This means: don't read or write history files; don't allow +suspending; don't allow spell checking; don't +allow a file to be appended to, prepended to, or saved under a different +name if it already has one; and don't make backup files. +Restricted mode can also be activated by invoking @command{nano} with +any name beginning with @code{r} (e.g.@: @command{rnano}). + +@item -S +@itemx --softwrap +Display over multiple screen rows lines that exceed the screen's width. +(You can make this soft-wrapping occur at whitespace instead of rudely at +the screen's edge, by using also @code{--atblanks}.) +(The old short option, @code{-$}, is deprecated.) + +@item -T @var{number} +@itemx --tabsize=@var{number} +Set the displayed tab length to @var{number} columns. The value of +@var{number} must be greater than 0. The default value is @t{8}. + +@item -U +@itemx --quickblank +Make status-bar messages disappear after 1 keystroke instead of after 20. +Note that option @option{-c} (@option{--constantshow}) overrides this. +When option @option{--minibar} or @option{--zero} is in effect, +@option{--quickblank} makes a message disappear after +0.8 seconds instead of after the default 1.5 seconds. + +@item -V +@itemx --version +Show the current version number and exit. + +@item -W +@itemx --wordbounds +Detect word boundaries differently by treating punctuation +characters as parts of words. + +@item -X "@var{characters}" +@itemx --wordchars="@var{characters}" +Specify which other characters (besides the normal alphanumeric ones) +should be considered as parts of words.

When enabled, mouse +clicks can be used to place the cursor, set the mark (with a double +click), and execute shortcuts. The mouse will work in the X Window +System, and on the console when gpm is running. Text can still be +selected through dragging by holding down the Shift key. + +@item -n +@itemx --noread +Treat any name given on the command line as a new file. This allows +@command{nano} to write to named pipes: it will start with a blank buffer, +and will write to the pipe when the user saves the "file".

The latter are toggled with @kbd{M-X}. + +@end table + + +@node Nanorc Files +@chapter Nanorc Files + +Nanorc files can be used to configure @command{nano} to your liking +without using command-line options. During startup @command{nano} will +normally read two files: first the system-wide file, @file{/etc/nanorc} +(the exact path may be different on your system), and then the user-specific +file, either @file{~/.nanorc} or @file{$XDG_CONFIG_HOME/nano/nanorc} or +@file{.config/nano/nanorc}, whichever exists first. +However, if @option{--rcfile} is given, @command{nano} will skip the +above files and will read just the specified settings file. + +A nanorc file can contain @command{set} and @command{unset} commands for +various options (@pxref{Settings}). It can also contain commands that +define syntax highlighting (@pxref{Syntax Highlighting}) and commands +that rebind keys (@ref{Rebinding Keys}). Each command should be on a +separate line, and all commands should be written in lowercase. + +Options that do not take an argument are unset by default. So using +the @code{unset} command is only needed when wanting to override a +setting from the system's nanorc file in your own nanorc. Options that +take an argument cannot be unset, but can be assigned the empty string. + +Any command-line option overrides its nanorc setting, of course. + +Quotes inside the @var{characters} parameters below should not be escaped. +The last double quote on the line will be seen as the closing quote. + +@menu +* Settings:: +* Syntax Highlighting:: +* Rebinding Keys:: +@end menu + +@node Settings +@section Settings + +The supported settings in a nanorc file are: + +@table @code + +@item set afterends +Make @kbd{Ctrl+Right} and @kbd{Ctrl+Delete} stop at word ends +instead of beginnings. + +@item set allow_insecure_backup +When backing up files, allow the backup to succeed even if its +permissions can't be (re)set due to special OS considerations. +You should NOT enable this option unless you are sure you need it. + +@item set atblanks +When soft line wrapping is enabled, make it wrap lines at blank characters +(tabs and spaces) instead of always at the edge of the screen. + +@item set autoindent +Automatically indent a newly created line to the same number of tabs +and/or spaces as the previous line (or as the next line if the previous +line is the beginning of a paragraph). + +@item set backup +When saving a file, back up the previous version of it, using the current +filename suffixed with a tilde (@code{~}). + +@item set backupdir "@var{directory}" +Make and keep not just one backup file, but make and keep a uniquely +numbered one every time a file is saved --- when backups are enabled +with @code{set backup} or @option{--backup} or @option{-B}. +The uniquely numbered files are stored in the specified directory. + +@item set boldtext +Use bold instead of reverse video for the title bar, status bar, key combos, +function tags, line numbers, and selected text.

This means that @code{.}, @code{?}, @code{*}, @code{+}, @code{^}, +@code{$}, and several other characters are special. +The period @code{.} matches any single character, +@code{?} means the preceding item is optional, +@code{*} means the preceding item may be matched zero or more times, +@code{+} means the preceding item must be matched one or more times, +@code{^} matches the beginning of a line, and @code{$} the end, +@code{\<} matches the start of a word, and @code{\>} the end, +and @code{\s} matches a blank. +It also means that lookahead and lookbehind are not possible. +A complete explanation can be found in the manual of GNU grep: +@code{info grep regular}. + +Each regular expression in a @file{nanorc} file should be wrapped in +double quotes (@code{""}). Multiple regular expressions can follow +each other on a line by separating them with blanks. This means that +a regular expression cannot contain a double quote followed by a blank. +When you need this combination inside a regular expression, +then either the double quote or the blank should be put +between square brackets (@code{[]}). + +A separate syntax can be defined for each kind of file +via the following commands in a nanorc file: + +@table @code + +@item syntax @var{name} ["@var{fileregex}" @dots{}] +Start the definition of a syntax with this @var{name}. +All subsequent @code{color} and other such commands +will be added to this syntax, until a new @code{syntax} +command is encountered. + +When @command{nano} is run, this syntax will be automatically +activated if the current filename matches the extended regular +expression @var{fileregex}. Or the syntax can be explicitly +activated by using the @option{-Y} or @option{--syntax} +command-line option followed by the @var{name}. + +The @code{default} syntax is special: it takes no @var{fileregex}, +and applies to files that don't match any syntax's regexes. +The @code{none} syntax is reserved; specifying it on the +command line is the same as not having a syntax at all. + +@item header "@var{regex}" @dots{} +If from all defined syntaxes no @var{fileregex} matched, then compare +this @var{regex} (or regexes) against the first line of the current file, +to determine whether this syntax should be used for it. + +@item magic "@var{regex}" @dots{} +If no @var{fileregex} matched and no @code{header} regex matched +either, then compare this @var{regex} (or regexes) against the +result of querying the @code{magic} database about the current +file, to determine whether this syntax should be used for it. +(This functionality only works when @code{libmagic} is installed +on the system and will be silently ignored otherwise.) + +@item formatter @var{program} [@var{argument} @dots{}] +Run the given @var{program} on the full contents of the current buffer. + +@item linter @var{program} [@var{argument} @dots{}] +Use the given @var{program} to do a syntax check on the current buffer. + +@item comment "@var{string}" +Use the given string for commenting and uncommenting lines. +If the string contains a vertical bar or pipe character (@t{|}), +this designates bracket-style comments; for example, @t{"/*|*/"} for +CSS files.

If no pipe +character is present, the full string is prepended; for example, @t{"#"} for +Python files.

For @code{bind} it means +all menus where the specified @code{function} exists; for @code{unbind} +it means all menus where the specified @code{key} exists. + +@end table + + +@node Pico Compatibility +@chapter Pico Compatibility + +@command{nano} emulates Pico quite closely, but there +are some differences between the two editors: + +@table @code + +@item Hard-Wrapping +Unlike Pico, @command{nano} does not automatically hard-wrap the current +line when it becomes overlong during typing. This hard-wrapping can be +switched on with the @option{--breaklonglines} option. With that option, +@command{nano} by default breaks lines at screen width minus eight columns, +whereas Pico does it at screen width minus six columns. You can make +@command{nano} do as Pico by using @option{--fill=-6}. + +@item Scrolling +By default, @command{nano} will scroll just one line (instead of half +a screen) when the cursor is moved to a line that is just out of view. +And when paging up or down, @command{nano} keeps the cursor in the same +screen position as much as possible, instead of always placing it on the +first line of the viewport. The Pico-like behavior can be obtained +with the @option{--jumpyscrolling} option. + +@item Edit Area +Pico never uses the line directly below the title bar, leaving it always +blank. @command{nano} includes this line in the editing area, in order +to not waste space, and because in this way it is slightly clearer where +the text starts. If you are accustomed to this line being empty, you can +get it back with the @option{--emptyline} option. + +@item Interactive Replace +Instead of allowing you to replace either just one occurrence of a search +string or all of them, @command{nano}'s replace function is interactive: it +will pause at each found search string and query whether to replace this +instance. You can then choose Yes, or No (skip this one), or All (don't +ask any more), or Cancel (stop with replacing). + +@item Search and Replace History +When the option @option{-H} or @option{--historylog} is given (or set in +a nanorc file), text entered as search or replace strings is stored. +These strings can be accessed with the up/down arrow keys at their +respective prompts, or you can +type the first few characters and then use @kbd{Tab} to cycle through the +matching strings. A retrieved string can subsequently be edited. + +@item Position History +When the option @option{-P} or @option{--positionlog} is given (or set in +a nanorc file), @command{nano} will store the position of the cursor +when you close a file, and will place the cursor in that position +again when you later reopen the file. + +@item Current Cursor Position +The output of the "Display Cursor Position" command (@kbd{^C}) displays +not only the current line and character position of the cursor, +but also (between the two) the current column position. + +@item Spell Checking +In the internal spell checker misspelled words are sorted alphabetically +and trimmed for uniqueness, such that the words 'apple' and 'Apple' will +be prompted for correction separately. + +@item Writing Selected Text to Files +When using the Write-Out key (@kbd{^O}), text that has been selected using the +marking key (@kbd{^^}) can not just be written out to a new (or existing) file, +it can also be appended or prepended to an existing file. + +@item Reading Text from a Command +When using the Read-File key (@kbd{^R}), @command{nano} can not just read a file, +it can also read the output of a command to be run (@kbd{^X}). + +@item Reading from Working Directory +By default, Pico will read files from the user's home directory (when +using @kbd{^R}), but it will write files to the current working directory +(when using @kbd{^O}). @command{nano} makes this symmetrical: always reading +from and writing to the current working directory --- the directory +that @command{nano} was started in. + +@item File Browser +In the file browser, @command{nano} does not implement the Add, Copy, +Rename, and Delete commands that Pico provides. In @command{nano} the +browser is just a file browser, not a file manager. + +@item Toggles +Many options which alter the functionality of the program can be +"toggled" on or off using Meta key sequences, meaning the program does +not have to be restarted to turn a particular feature on or off. +@xref{Feature Toggles} for a list of options that can be toggled. +Or see the list at the end of the main internal help text (@kbd{^G}) instead. + +@end table + + +@node Building and its Options +@chapter Building and its Options + +Building @command{nano} from source is straightforward if you are +familiar with compiling programs with autoconf support: + +@blankline +@example + tar -xf nano-x.y.tar.gz + cd nano-x.y + ./configure + make + make install +@end example +@blankline + +The possible options to @code{./configure} are: + +@table @code + +@item --disable-browser +Exclude the file browser that can be called with @kbd{^T} when +wanting to read or write a file. + +@item --disable-color +Exclude support for syntax coloring. This also eliminates the @option{-Y} +command-line option, which allows choosing a specific syntax. + +@item --disable-comment +Exclude the single-keystroke comment/uncomment function (@w{@kbd{M-3}}). + +@item --disable-extra +Exclude the Easter egg: a crawl of major contributors. + +@item --disable-formatter +Exclude the code for calling a formatting tool. + +@item --disable-help +Exclude the help texts (@kbd{^G}). This makes the binary much smaller, +but also makes it difficult for new users to learn more than very basic +things about using the editor. + +@item --disable-histories +Exclude the code for handling the history files: the search and +replace strings that were used, the commands that were executed, +and the cursor position at which each file was closed. +This also eliminates the @option{-H} and @option{-P} command-line +options, which switch on the storing of search/replace strings, +executed commands, and cursor positions. + +@item --disable-justify +Exclude the text-justification functions (@kbd{^J} and @kbd{M-J}). + +@item --disable-libmagic +Exclude the code for using the library of magic-number tests (for +determining the file type and thus which syntax to use for coloring --- +in most cases the regexes for filename and header line will be enough). + +@item --disable-linenumbers +Exclude the ability to show line numbers. This also eliminates +the @option{-l} command-line option, which turns line numbering on. + +@item --disable-linter +Exclude the code for calling a linting tool. + +@item --disable-mouse +Exclude all mouse functionality. This also eliminates the @option{-m} +command-line option, which enables the mouse functionality. + +@item --disable-multibuffer +Exclude support for opening multiple files at a time and switching +between them. This also eliminates the @option{-F} command-line option, +which causes a file to be read into a separate buffer by default. + +@item --disable-nanorc +Exclude support for reading the nanorc files at startup. With such +support, you can store custom settings in a system-wide and a per-user +nanorc file rather than having to pass command-line options to get +the desired behavior. @xref{Nanorc Files} for more info. +Disabling this also eliminates the @option{-I} command-line option, +which inhibits the reading of nanorc files. + +@item --disable-operatingdir +Exclude the code for setting an operating directory. This also eliminates +the @option{-o} command-line option, which sets the operating directory. + +@item --disable-speller +Exclude the code for spell checking. This also eliminates the @option{-s} +command-line option, which allows specifying an alternate spell checker. + +@item --disable-tabcomp +Exclude tab completion (when nano asks for a filename or search string +or replace string or command to execute). + +@item --disable-wordcomp +Exclude word completion (@kbd{^]}). + +@item --disable-wrapping +Exclude all hard-wrapping of overlong lines. This also eliminates the +@option{-b} and @option{-w} command-line options, which switch automatic +long-line wrapping on and off, respectively. + +@item --enable-tiny +This option implies all of the above. It also disables some other +internals of the editor, like the function toggles, the marking of text, +the undo/redo code, line anchors, the recording and playback of a macro, +softwrapping, and the cut-to-end-of-line code. These things stay disabled +also when using the enabling counterpart of the above options together with +@option{--enable-tiny} to switch specific features back on. + +@item --enable-debug +Include some code for runtime debugging output. This can get messy, so +chances are you only want this feature when you're working on the nano source. + +@item --disable-nls +Exclude Native Language support. This will disable the use of any +available GNU @command{nano} translations. + +@item --enable-utf8 +Include support for handling and displaying Unicode files. +This requires a "wide" version of the curses library. + +@item --disable-utf8 +Exclude support for handling and displaying Unicode files. Normally the +configure script auto-detects whether to enable UTF-8 support or not. +You can use this or the previous option to override that detection. + +@item --enable-altrcname=@var{name} +Use the file with the given @var{name} (in the user's home directory) +as nano's settings file, instead of the default @code{.nanorc}. + +@end table + +@html +

During startup, if \fB\-\-rcfile\fR +is not given, \fBnano\fR will read two files: first the +system-wide settings, from \fI/etc/nanorc\fP (the exact path might be +different on your system), and then the user-specific settings, either +from \fI~/.nanorc\fR or from \fI$XDG_CONFIG_HOME/nano/nanorc\fR +or from \fI~/.config/nano/nanorc\fR, whichever is encountered first. +If \fB\-\-rcfile\fR is given, \fBnano\fR will read just the specified +settings file. + +.SH OPTIONS +The configuration file accepts a series of \fBset\fP and \fBunset\fP +commands, which can be used to configure nano on startup without using +command-line options. Additionally, there are some commands to define +syntax highlighting and to rebind keys -- see the two separate sections +on those. \fBnano\fP reads one command per line. +All commands and keywords should be written in lowercase. +.sp +Options in \fInanorc\fP files take precedence over nano's defaults, and +command-line options override \fInanorc\fP settings. Also, options that +do not take an argument are unset by default. So using the \fBunset\fR +command is only needed when wanting to override a setting of the system's +\fInanorc\fR file in your own \fInanorc\fR. Options that take an +argument cannot be unset. +.sp +Quotes inside the \fIcharacters\fR parameters below should not be escaped. +The last double quote on the line will be seen as the closing quote. +.sp +The supported commands and arguments are: +.TP 3 +.B set afterends +Make Ctrl+Right and Ctrl+Delete stop at word ends instead of beginnings. +.TP +.B set allow_insecure_backup +When backing up files, allow the backup to succeed even if its permissions +can't be (re)set due to special OS considerations. You should +NOT enable this option unless you are sure you need it. +.TP +.B set atblanks +When soft line wrapping is enabled, make it wrap lines at blank characters +(tabs and spaces) instead of always at the edge of the screen. +.TP +.B set autoindent +Automatically indent a newly created line to the same number of tabs +and/or spaces as the previous line (or as the next line if the previous +line is the beginning of a paragraph). +.TP +.B set backup +When saving a file, create a backup file by adding a tilde (\fB~\fP) to +the file's name. +.TP +.B set backupdir "\fIdirectory\fP" +Make and keep not just one backup file, but make and keep a uniquely +numbered one every time a file is saved -- when backups are enabled +with \fBset backup\fR or \fB\-\-backup\fR or \fB\-B\fR. +The uniquely numbered files are stored in the specified \fIdirectory\fR. +.TP +.B set boldtext +Use bold instead of reverse video for the title bar, status bar, key combos, +function tags, line numbers, and selected text. This can be overridden by +setting the options \fBtitlecolor\fP, \fBstatuscolor\fP, \fBkeycolor\fP, +\fBfunctioncolor\fP, \fBnumbercolor\fP, and \fBselectedcolor\fP. +.TP +.B set bookstyle +When justifying, treat any line that starts with whitespace as the +beginning of a paragraph (unless auto-indenting is on). +.TP +.BI "set brackets """ characters """ +Set the characters treated as closing brackets when justifying +paragraphs.

This may not include blank characters. The opening set must +come before the closing set, and the two sets must be in the same order. +The default value is "\fB(<[{)>]}\fP". +.TP +.B set minibar +Suppress the title bar and instead show information about +the current buffer at the bottom of the screen, in the space +for the status bar. In this "minibar" the filename is shown +on the left, followed by an asterisk if the buffer has been modified. +On the right are displayed the current line and column number, the +code of the character under the cursor (in Unicode format: U+xxxx), +the same flags as are shown by \fBset stateflags\fR, and a percentage +that expresses how far the cursor is into the file (linewise). +When a file is loaded or saved, and also when switching between buffers, +the number of lines in the buffer is displayed after the filename. +This number is cleared upon the next keystroke, or replaced with an +[i/n] counter when multiple buffers are open. +The line plus column numbers and the character code are displayed only when +\fBset constantshow\fR is used, and can be toggled on and off with \fBM\-C\fR. +The state flags are displayed only when \fBset stateflags\fR is used. +.TP +.B set minicolor \fR[\fBbold,\fR][\fBitalic,\fR]\fIfgcolor\fB,\fIbgcolor\fR +Use this color combination for the minibar. +(When this option is not specified, the colors of the title bar are used.) +See \fBset titlecolor\fR for more details. +.TP +.B set mouse +Enable mouse support, if available for your system.

Nevertheless, regular +expressions can do a lot and are easy to make, so they are a +good fit for a small editor like \fBnano\fR. +.sp +All regular expressions in \fBnano\fR are POSIX extended regular expressions. +This means that \fB.\fR, \fB?\fR, \fB*\fR, \fB+\fR, \fB^\fR, \fB$\fR, and +several other characters are special. +The period \fB.\fR matches any single character, +\fB?\fR means the preceding item is optional, +\fB*\fR means the preceding item may be matched zero or more times, +\fB+\fR means the preceding item must be matched one or more times, +\fB^\fR matches the beginning of a line, and \fB$\fR the end, +\fB\\<\fR matches the start of a word, and \fB\\>\fR the end, +and \fB\\s\fR matches a blank. +It also means that lookahead and lookbehind are not possible. +A complete explanation can be found in the manual page of GNU grep: +\fBman grep\fR. +.sp +Each regular expression in a \fBnanorc\fR file should be wrapped in +double quotes (\fB""\fR). Multiple regular expressions can follow +each other on a line by separating them with blanks. This means that +a regular expression cannot contain a double quote followed by a blank. +When you need this combination inside a regular expression, +then either the double quote or the blank should be put +between square brackets (\fB[]\fR). +.sp +For each kind of file a separate syntax can be defined +via the following commands: +.TP +.BI syntax " name \fR[" """" fileregex """ " \fR...] +Start the definition of a syntax with this \fIname\fR. +All subsequent \fBcolor\fR and other such commands +will be added to this syntax, until a new \fBsyntax\fR +command is encountered. +.sp +When \fBnano\fR is run, this syntax will be automatically +activated if the current filename matches the extended regular +expression \fIfileregex\fR.

nanorc - GNU +nano’s configuration file

+ +

DESCRIPTION + +

+ + +

The +nanorc files contain the default settings for +nano, a small and friendly editor. During startup, if +--rcfile is not given, nano will read two +files: first the system-wide settings, from +/etc/nanorc (the exact path might be different on +your system), and then the user-specific settings, either +from ~/.nanorc or from +$XDG_CONFIG_HOME/nano/nanorc or from +~/.config/nano/nanorc, whichever is encountered +first. If --rcfile is given, nano will read +just the specified settings file.

+ +

OPTIONS + +

+ + +

The +configuration file accepts a series of set and +unset commands, which can be used to configure nano +on startup without using command-line options. Additionally, +there are some commands to define syntax highlighting and to +rebind keys -- see the two separate sections on those. +nano reads one command per line. All commands and +keywords should be written in lowercase.

+ +

Options in +nanorc files take precedence over nano’s +defaults, and command-line options override nanorc +settings. Also, options that do not take an argument are +unset by default. So using the unset command is only +needed when wanting to override a setting of the +system’s nanorc file in your own nanorc. +Options that take an argument cannot be unset.

+ +

Quotes inside +the characters parameters below should not be +escaped. The last double quote on the line will be seen as +the closing quote.

+ +

The supported +commands and arguments are:
+set afterends

+ +

Make Ctrl+Right and Ctrl+Delete +stop at word ends instead of beginnings.

+ +

set +allow_insecure_backup

+ +

When backing up files, allow +the backup to succeed even if its permissions can’t be +(re)set due to special OS considerations. You should NOT +enable this option unless you are sure you need it.

+ +

set atblanks

+ +

When soft line wrapping is +enabled, make it wrap lines at blank characters (tabs and +spaces) instead of always at the edge of the screen.

+ +

set autoindent

+ +

Automatically indent a newly +created line to the same number of tabs and/or spaces as the +previous line (or as the next line if the previous line is +the beginning of a paragraph).

+ +

set backup

+ +

When saving a file, create a +backup file by adding a tilde (~) to the file’s +name.

+ +

set backupdir +directory

+ +

Make and keep not just one +backup file, but make and keep a uniquely numbered one every +time a file is saved -- when backups are enabled with set +backup or --backup or -B. The uniquely +numbered files are stored in the specified +directory.

+ +

set boldtext

+ +

Use bold instead of reverse +video for the title bar, status bar, key combos, function +tags, line numbers, and selected text. This can be +overridden by setting the options titlecolor, +statuscolor, keycolor, functioncolor, +numbercolor, and selectedcolor.

+ +

set bookstyle

+ +

When justifying, treat any line +that starts with whitespace as the beginning of a paragraph +(unless auto-indenting is on).

+ +

set brackets +"characters"

+ +

Set the characters treated as +closing brackets when justifying paragraphs. This may not +include blank characters. Only closing punctuation (see +set punct), optionally followed by the specified +closing brackets, can end sentences. The default value is +""’)>]}".

+ +

set breaklonglines

+ +

Automatically hard-wrap the +current line when it becomes overlong.

+ +

set casesensitive

+ +

Do case-sensitive searches by +default.

+ +

set constantshow

+ +

Constantly display the cursor +position in the status bar. This overrides the option +quickblank.

+ +

set cutfromcursor

+ +

Use +cut-from-cursor-to-end-of-line by default, instead of +cutting the whole line.

+ +

set emptyline

+ +

Do not use the line below the +title bar, leaving it entirely blank.

+ +

set errorcolor +[bold,][italic,]fgcolor,bgcolor

+ +

Use this color combination for +the status bar when an error message is displayed. The +default value is bold,white,red. See set +titlecolor for valid color names.

+ +

set fill +number

+ +

Set the target width for +justifying and automatic hard-wrapping at this number +of columns. If the value is 0 or less, wrapping will occur +at the width of the screen minus number columns, +allowing the wrap point to vary along with the width of the +screen if the screen is resized. The default value is +-8.

+ +

set functioncolor +[bold,][italic,]fgcolor,bgcolor

+ +

Use this color combination for +the concise function descriptions in the two help lines at +the bottom of the screen. See set titlecolor for more +details.

+ +

set guidestripe +number

+ +

Draw a vertical stripe at the +given column, to help judge the width of the text. (The +color of the stripe can be changed with set +stripecolor.)

+ +

set historylog

+ +

Save the last hundred search +strings and replacement strings and executed commands, so +they can be easily reused in later sessions.

+ +

set indicator

+ +

Display a "scrollbar" +on the righthand side of the edit window. It shows the +position of the viewport in the buffer and how much of the +buffer is covered by the viewport.

+ +

set jumpyscrolling

+ +

Scroll the buffer contents per +half-screen instead of per line.

+ +

set keycolor +[bold,][italic,]fgcolor,bgcolor

+ +

Use this color combination for +the shortcut key combos in the two help lines at the bottom +of the screen. See set titlecolor for more +details.

+ +

set linenumbers

+ +

Display line numbers to the +left of the text area. (Any line with an anchor additionally +gets a mark in the margin.)

+ +

set locking

+ +

Enable vim-style lock-files for +when editing files.

+ +

set magic

+ +

When neither the file’s +name nor its first line give a clue, try using libmagic to +determine the applicable syntax. (Calling libmagic can be +relatively time consuming. It is therefore not done by +default.)

+ +

set matchbrackets +"characters"

+ +

Specify the opening and closing +brackets that can be found by bracket searches. This may not +include blank characters. The opening set must come before +the closing set, and the two sets must be in the same order. +The default value is "(<[{)>]}".

+ +

set minibar

+ +

Suppress the title bar and +instead show information about the current buffer at the +bottom of the screen, in the space for the status bar. In +this "minibar" the filename is shown on the left, +followed by an asterisk if the buffer has been modified. On +the right are displayed the current line and column number, +the code of the character under the cursor (in Unicode +format: U+xxxx), the same flags as are shown by set +stateflags, and a percentage that expresses how far the +cursor is into the file (linewise). When a file is loaded or +saved, and also when switching between buffers, the number +of lines in the buffer is displayed after the filename. This +number is cleared upon the next keystroke, or replaced with +an [i/n] counter when multiple buffers are open. The line +plus column numbers and the character code are displayed +only when set constantshow is used, and can be +toggled on and off with M-C. The state flags are +displayed only when set stateflags is used.

+ +

set minicolor +[bold,][italic,]fgcolor,bgcolor

+ +

Use this color combination for +the minibar. (When this option is not specified, the colors +of the title bar are used.) See set titlecolor for +more details.

+ +

set mouse

+ +

Enable mouse support, if +available for your system. When enabled, mouse clicks can be +used to place the cursor, set the mark (with a double +click), and execute shortcuts. The mouse will work in the X +Window System, and on the console when gpm is running. Text +can still be selected through dragging by holding down the +Shift key.

+ +

set multibuffer

+ +

When reading in a file with +^R, insert it into a new buffer by default.

+ +

set noconvert

+ +

Don’t convert files from +DOS/Mac format.

+ +

set nohelp

+ +

Don’t display the two +help lines at the bottom of the screen.

+ +

set nonewlines

+ +

Don’t automatically add a +newline when a text does not end with one. (This can cause +you to save non-POSIX text files.)

+ +

set nowrap

+ +

Deprecated option since it has +become the default setting. When needed, use unset +breaklonglines instead.

+ +

set numbercolor +[bold,][italic,]fgcolor,bgcolor

+ +

Use this color combination for +line numbers. See set titlecolor for more +details.

+ +

set operatingdir +directory

+ +

nano will only read and +write files inside directory and its subdirectories. +Also, the current directory is changed to here, so files are +inserted from this directory. By default, the operating +directory feature is turned off.

+ +

set positionlog

+ +

Save the cursor position of +files between editing sessions. The cursor position is +remembered for the 200 most-recently edited files.

+ +

set preserve

+ +

Preserve the XON and XOFF keys +(^Q and ^S).

+ +

set promptcolor +[bold,][italic,]fgcolor,bgcolor

+ +

Use this color combination for +the prompt bar. (When this option is not specified, the +colors of the title bar are used.) See set titlecolor +for more details.

+ +

set punct +"characters"

+ +

Set the characters treated as +closing punctuation when justifying paragraphs. This may not +include blank characters. Only the specfified closing +punctuation, optionally followed by closing brackets (see +brackets), can end sentences. The default value is +"!.?".

+ +

set quickblank

+ +

Make status-bar messages +disappear after 1 keystroke instead of after 20. Note that +option constantshow overrides this. When option +minibar or zero is in effect, +quickblank makes a message disappear after 0.8 +seconds instead of after the default 1.5 seconds.

+ +

set quotestr +"regex"

+ +

Set the regular expression for +matching the quoting part of a line. The default value is +"^([ \t]*([!#%:;>|}]|//))+". (Note +that \t stands for an actual Tab character.) This +makes it possible to rejustify blocks of quoted text when +composing email, and to rewrap blocks of line comments when +writing source code.

+ +

set rawsequences

+ +

Interpret escape sequences +directly, instead of asking ncurses to translate +them. (If you need this option to get some keys to work +properly, it means that the terminfo terminal description +that is used does not fully match the actual behavior of +your terminal. This can happen when you ssh into a BSD +machine, for example.) Using this option disables +nano’s mouse support.

+ +

set rebinddelete

+ +

Interpret the Delete and +Backspace keys differently so that both Backspace and Delete +work properly. You should only use this option when on your +system either Backspace acts like Delete or Delete acts like +Backspace.

+ +

set regexp

+ +

Do regular-expression searches +by default. Regular expressions in nano are of the +extended type (ERE).

+ +

set saveonexit

+ +

Save a changed buffer +automatically on exit (^X); don’t prompt.

+ +

set scrollercolor +fgcolor,bgcolor

+ +

Use this color combination for +the indicator alias "scrollbar". (On terminal +emulators that link to a libvte older than version 0.55, +using a background color here does not work correctly.) See +set titlecolor for more details.

+ +

set selectedcolor +[bold,][italic,]fgcolor,bgcolor

+ +

Use this color combination for +selected text. See set titlecolor for more +details.

+ +

set showcursor

+ +

Put the cursor on the +highlighted item in the file browser, and show the cursor in +the help viewer, to aid braille users and people with poor +vision.

+ +

set smarthome

+ +

Make the Home key smarter. When +Home is pressed anywhere but at the very beginning of +non-whitespace characters on a line, the cursor will jump to +that beginning (either forwards or backwards). If the cursor +is already at that position, it will jump to the true +beginning of the line.

+ +

set softwrap

+ +

Display lines that exceed the +screen’s width over multiple screen lines. (You can +make this soft-wrapping occur at whitespace instead of +rudely at the screen’s edge, by using also set +atblanks.)

+ +

set speller +"program [argument +...]"

+ +

Use the given program to +do spell checking and correcting, instead of using the +built-in corrector that calls hunspell(1) or +spell(1).

+ +

set spotlightcolor +[bold,][italic,]fgcolor,bgcolor

+ +

Use this color combination for +highlighting a search match. The default value is +black,lightyellow. See set titlecolor for +valid color names.

+ +

set stateflags

+ +

Use the top-right corner of the +screen for showing some state flags: I when +auto-indenting, M when the mark is on, L when +hard-wrapping (breaking long lines), R when recording +a macro, and S when soft-wrapping. When the buffer is +modified, a star (*) is shown after the filename in +the center of the title bar.

+ +

set statuscolor +[bold,][italic,]fgcolor,bgcolor

+ +

Use this color combination for +the status bar. See set titlecolor for more +details.

+ +

set stripecolor +[bold,][italic,]fgcolor,bgcolor

+ +

Use this color combination for +the vertical guiding stripe. See set titlecolor for +more details.

+ +

set tabsize +number

+ +

Use a tab size of number +columns. The value of number must be greater than 0. +The default value is 8.

+ +

set tabstospaces

+ +

Convert each typed tab to +spaces -- to the number of spaces that a tab at that +position would take up.

+ +

set titlecolor +[bold,][italic,]fgcolor,bgcolor

+ +

Use this color combination for +the title bar. Valid names for the foreground and background +colors are: red, green, blue, +magenta, yellow, cyan, white, +and black. Each of these eight names may be prefixed +with the word light to get a brighter version of that +color. The word grey or gray may be used as a +synonym for lightblack. On terminal emulators that +can do at least 256 colors, other valid (but unprefixable) +color names are: pink, purple, mauve, +lagoon, mint, lime, peach, +orange, latte, rosy, beet, +plum, sea, sky, slate, +teal, sage, brown, ocher, +sand, tawny, brick, crimson, and +normal -- where normal means the default +foreground or background color. On such emulators, the color +may also be specified as a three-digit hexadecimal number +prefixed with #, with the digits representing the +amounts of red, green, and blue, respectively. This tells +nano to select from the available palette the color +that approximates the given values.

+ +

Either +"fgcolor" or +",bgcolor" may be left out, and the +pair may be preceded by bold and/or italic +(separated by commas) to get a bold and/or slanting +typeface, if your terminal can do those.

+ +

set trimblanks

+ +

Remove trailing whitespace from +wrapped lines when automatic hard-wrapping occurs or when +text is justified.

+ +

set unix

+ +

Save a file by default in Unix +format. This overrides nano’s default behavior of +saving a file in the format that it had. (This option has no +effect when you also use set noconvert.)

+ +

set whitespace +"characters"

+ +

Set the two characters used to +indicate the presence of tabs and spaces. They must be +single-column characters. The default pair for a UTF-8 +locale is "»⋅", and for other +locales ">.".

+ +

set wordbounds

+ +

Detect word boundaries +differently by treating punctuation characters as parts of +words.

+ +

set wordchars +"characters"

+ +

Specify which other characters +(besides the normal alphanumeric ones) should be considered +as parts of words. When using this option, you probably want +to unset wordbounds.

+ +

set zap

+ +

Let an unmodified Backspace or +Delete erase the marked region (instead of a single +character, and without affecting the cutbuffer).

+ +

set zero

+ +

Hide all elements of the +interface (title bar, status bar, and help lines) and use +all rows of the terminal for showing the contents of the +buffer. The status bar appears only when there is a +significant message, and disappears after 1.5 seconds or +upon the next keystroke. With M-Z the title bar plus +status bar can be toggled. With M-X the help +lines.

+ +

NOTES + +

+ + +

Option set +suspendable has been removed. Suspension is enabled by +default, reachable via ^T^Z. (If you want a plain +^Z to suspend nano, add bind ^Z suspend main +to your nanorc.)

+ +

SYNTAX HIGHLIGHTING + +

+ + +

Coloring the +different syntactic elements of a file is done via regular +expressions (see the color command below). This is +inherently imperfect, because regular expressions are not +powerful enough to fully parse a file. Nevertheless, regular +expressions can do a lot and are easy to make, so they are a +good fit for a small editor like nano.

+ +

All regular +expressions in nano are POSIX extended regular +expressions. This means that ., ?, *, ++, ^, $, and several other characters +are special. The period . matches any single +character, ? means the preceding item is optional, +* means the preceding item may be matched zero or +more times, + means the preceding item must be +matched one or more times, ^ matches the beginning of +a line, and $ the end, \< matches the start +of a word, and \> the end, and \s matches a +blank. It also means that lookahead and lookbehind are not +possible. A complete explanation can be found in the manual +page of GNU grep: man grep.

+ +

Each regular +expression in a nanorc file should be wrapped in +double quotes (""). Multiple regular +expressions can follow each other on a line by separating +them with blanks. This means that a regular expression +cannot contain a double quote followed by a blank. When you +need this combination inside a regular expression, then +either the double quote or the blank should be put between +square brackets ([]).

+ +

For each kind +of file a separate syntax can be defined via the following +commands:
+syntax name +["fileregex" ...]

+ +

Start the definition of a +syntax with this name. All subsequent color +and other such commands will be added to this syntax, until +a new syntax command is encountered.

+ +

When +nano is run, this syntax will be automatically +activated if the current filename matches the extended +regular expression fileregex. Or the syntax can be +explicitly activated by using the -Y or +--syntax command-line option followed by the +name.

+ +

The syntax +default is special: it takes no fileregex, and +applies to files that don’t match any syntax’s +regexes. The syntax none is reserved; specifying it +on the command line is the same as not having a syntax at +all.

+ +

header +"regex" ...

+ +

If from all defined syntaxes no +fileregex matched, then compare this regex (or +regexes) against the first line of the current file, to +determine whether this syntax should be used for it.

+ +

magic +"regex" ...

+ +

If no fileregex matched +and no header regex matched either, then compare this +regex (or regexes) against the result of querying the +magic database about the current file, to determine +whether this syntax should be used for it. (This +functionality only works when libmagic is installed +on the system and will be silently ignored otherwise.)

+ +

formatter program +[argument ...]

+ +

Run the given program on +the full contents of the current buffer.

+ +

linter program +[argument ...]

+ +

Use the given program to +run a syntax check on the current buffer.

+ +

comment +"string"

+ +

Use the given string for +commenting and uncommenting lines. If the string contains a +vertical bar or pipe character (|), this designates +bracket-style comments; for example, +"/*|*/" for CSS files. The characters +before the pipe are prepended to the line and the characters +after the pipe are appended at the end of the line. If no +pipe character is present, the full string is prepended; for +example, "#" for Python files. If empty +double quotes are specified, the comment/uncomment function +is disabled; for example, "" for JSON. The default +value is "#".

+ +

tabgives +"string"

+ +

Make the <Tab> key +produce the given string. Useful for languages like +Python that want to see only spaces for indentation. This +overrides the setting of the tabstospaces option.

+ +

color +[bold,][italic,]fgcolor,bgcolor +"regex" ...

+ +

Paint all pieces of text that +match the extended regular expression regex with the +given foreground and background colors, at least one of +which must be specified. Valid color names are: red, +green, blue, magenta, yellow, +cyan, white, and black. Each of these +eight names may be prefixed with the word light to +get a brighter version of that color. The word grey +or gray may be used as a synonym for +lightblack. On terminal emulators that can do at +least 256 colors, other valid (but unprefixable) color names +are: pink, purple, mauve, +lagoon, mint, lime, peach, +orange, latte, rosy, beet, +plum, sea, sky, slate, +teal, sage, brown, ocher, +sand, tawny, brick, crimson, and +normal -- where normal means the default +foreground or background color. On such emulators, the color +may also be specified as a three-digit hexadecimal number +prefixed with #, with the digits representing the +amounts of red, green, and blue, respectively. This tells +nano to select from the available palette the color +that approximates the given values.

+ +

The color pair +may be preceded by bold and/or italic +(separated by commas) to get a bold and/or slanting +typeface, if your terminal can do those.

+ +

All coloring +commands are applied in the order in which they are +specified, which means that later commands can recolor stuff +that was colored earlier.

+ +

icolor +[bold,][italic,]fgcolor,bgcolor +"regex" ...

+ +

Same as above, except that the +matching is case insensitive.

+ +

color +[bold,][italic,]fgcolor,bgcolor +start="fromrx" +end="torx"

+ +

Paint all pieces of text whose +start matches extended regular expression fromrx and +whose end matches extended regular expression torx +with the given foreground and background colors, at least +one of which must be specified. This means that, after an +initial instance of fromrx, all text until the first +instance of torx will be colored. This allows syntax +highlighting to span multiple lines.

+ +

icolor +[bold,][italic,]fgcolor,bgcolor +start="fromrx" +end="torx"

+ +

Same as above, except that the +matching is case insensitive.

+ +

include +"syntaxfile"

+ +

Read in self-contained color +syntaxes from syntaxfile. Note that syntaxfile +may contain only the above commands, from syntax to +icolor.

+ +

extendsyntax name +command argument ...

+ +

Extend the syntax previously +defined as name with another command. This +allows adding a new color, icolor, +header, magic, formatter, +linter, comment, or tabgives command to +an already defined syntax -- useful when you want to +slightly improve a syntax defined in one of the +system-installed files (which normally are not +writable).

+ +

REBINDING KEYS + +

+ + +

Key bindings +can be changed via the following three commands:

+ +

bind key function +menu

+ +

Rebinds the given key to +the given function in the given menu (or in +all menus where the function exists when all is +used).

+ +

bind key +"string" menu

+ +

Makes the given key +produce the given string in the given menu (or +in all menus where the key exists when all is used). +Besides literal text and/or control codes, the string +may contain function names between braces. These functions +will be invoked when the key is typed. To include a literal +opening brace, use {{}.

+ +

unbind key +menu

+ +

Unbinds the given key +from the given menu (or from all menus where the key +exists when all is used).

+ +

Note that +bind key +"{function}" menu is +equivalent to bind key function menu, except +that for the latter form nano will check the +availabilty of the function in the given menu +at startup time (and report an error if it does not exist +there), whereas for the first form nano will check at +execution time that the function exists but not +whether it makes any sense in the current menu. The user has +to take care that a function name between braces (or any +sequence of them) is appropriate. Strange behavior can +result when it is not.
+The format of key should be one of:

+ + + + + + + + + + + + + + + + + + + + + + +
+ + +

^X

 + + +

where X is a Latin letter, or one of several +ASCII characters (@, ], \, ^, _), or the word +"Space". Example: ^C.

+ + +

M-X

 + + +

where X is any ASCII character except [, or the +word "Space". Example: M-8.

+ + +

Sh-M-X

 + + +

where X is a Latin letter. Example: Sh-M-U. By +default, each Meta+letter keystroke does the same as the +corresponding Shift+Meta+letter. But when any Shift+Meta +bind is made, that will no longer be the case, for all +letters.

+ + +

FN

 + + +

where N is a numeric value from 1 to 24. Example: +F10. (Often, F13 to F24 can be typed as +F1 to F12 with Shift.)

+ +

Ins or Del.

+ +

Rebinding +^M (Enter) or ^I (Tab) is probably not a good +idea. Rebinding ^[ (Esc) is not possible, because its +keycode is the starter byte of Meta keystrokes and escape +sequences. Rebinding any of the dedicated cursor-moving keys +(the arrows, Home, End, PageUp and PageDown) is not +possible. On some terminals it’s not possible to +rebind ^H (unless --raw is used) because its +keycode is identical to that of the Backspace key.
+Valid function names to be bound are:

+ +

help

+ +

Invokes the help viewer.

+ +

cancel

+ +

Cancels the current +command.

+ +

exit

+ +

Exits from the program (or from +the help viewer or file browser).

+ +

writeout

+ +

Writes the current buffer to +disk, asking for a name.

+ +

savefile

+ +

Writes the current file to disk +without prompting.

+ +

insert

+ +

Inserts a file into the current +buffer (at the current cursor position), or into a new +buffer when option multibuffer is set.

+ +

whereis

+ +

Starts a forward search for +text in the current buffer -- or for filenames matching a +string in the current list in the file browser.

+ +

wherewas

+ +

Starts a backward search for +text in the current buffer -- or for filenames matching a +string in the current list in the file browser.

+ +

findprevious

+ +

Searches the next occurrence in +the backward direction.

+ +

findnext

+ +

Searches the next occurrence in +the forward direction.

+ +

replace

+ +

Interactively replaces text +within the current buffer.

+ +

cut

+ +

Cuts and stores the current +line (or the marked region).

+ +

copy

+ +

Copies the current line (or the +marked region) without deleting it.

+ +

paste

+ +

Pastes the currently stored +text into the current buffer at the current cursor +position.

+ +

zap

+ +

Throws away the current line +(or the marked region). (This function is bound by default +to <Meta+Delete>.)

+ +

chopwordleft

+ +

Deletes from the cursor +position to the beginning of the preceding word. (This +function is bound by default to <Shift+Ctrl+Delete>. +If your terminal produces ^H for +<Ctrl+Backspace>, you can make <Ctrl+Backspace> +delete the word to the left of the cursor by rebinding +^H to this function.)

+ +

chopwordright

+ +

Deletes from the cursor +position to the beginning of the next word. (This function +is bound by default to <Ctrl+Delete>.)

+ +

cutrestoffile

+ +

Cuts all text from the cursor +position till the end of the buffer.

+ +

mark

+ +

Sets the mark at the current +position, to start selecting text. Or, when it is set, +unsets the mark.

+ +

location

+ +

Reports the current position of +the cursor in the buffer: the line, column, and character +positions.

+ +

wordcount

+ +

Counts and reports on the +status bar the number of lines, words, and characters in the +current buffer (or in the marked region).

+ +

execute

+ +

Prompts for a program to +execute. The program’s output will be inserted into +the current buffer (or into a new buffer when M-F is +toggled).

+ +

speller

+ +

Invokes a spell-checking +program, either the default hunspell(1) or GNU +spell(1), or the one defined by --speller or +set speller.

+ +

formatter

+ +

Invokes a +full-buffer-processing program (if the active syntax defines +one). (The current buffer is written out to a temporary +file, the program is run on it, and then the temporary file +is read back in, replacing the contents of the buffer.)

+ +

linter

+ +

Invokes a syntax-checking +program (if the active syntax defines one). If this program +produces lines of the form "filename:linenum:charnum: +some message", then the cursor will be put at the +indicated position in the mentioned file while showing +"some message" on the status bar. You can move +from message to message with <PgUp> and <PgDn>, +and leave linting mode with ^C or <Enter>.

+ +

justify

+ +

Justifies the current paragraph +(or the marked region). A paragraph is a group of contiguous +lines that, apart from possibly the first line, all have the +same indentation. The beginning of a paragraph is detected +by either this lone line with a differing indentation or by +a preceding blank line.

+ +

fulljustify

+ +

complete

+ +

Completes (when possible) the +fragment before the cursor to a full word found elsewhere in +the current buffer.

+ +

left

+ +

Goes left one position (in the +editor or browser).

+ +

right

+ +

Goes right one position (in the +editor or browser).

+ +

up

+ +

Goes one line up (in the editor +or browser).

+ +

down

+ +

Goes one line down (in the +editor or browser).

+ +
