<h2>DESCRIPTION
|
|
<a name="DESCRIPTION"></a>
|
|
</h2>
|
|
|
|
|
|
<p style="margin-left:11%; margin-top: 1em">The
|
|
<i>nanorc</i> files contain the default settings for
|
|
<b>nano</b>, a small and friendly editor. During startup, if
|
|
<b>--rcfile</b> is not given, <b>nano</b> will read two
|
|
files: first the system-wide settings, from
|
|
<i>/etc/nanorc</i> (the exact path might be different on
|
|
your system), and then the user-specific settings, either
|
|
from <i>~/.nanorc</i> or from
|
|
<i>$XDG_CONFIG_HOME/nano/nanorc</i> or from
|
|
<i>~/.config/nano/nanorc</i>, whichever is encountered
|
|
first. If <b>--rcfile</b> is given, <b>nano</b> will read
|
|
just the specified settings file.</p>
|
|
|
|
<h2>OPTIONS
|
|
<a name="OPTIONS"></a>
|
|
</h2>
|
|
|
|
|
|
<p style="margin-left:11%; margin-top: 1em">The
|
|
configuration file accepts a series of <b>set</b> and
|
|
<b>unset</b> 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.
|
|
<b>nano</b> reads one command per line. All commands and
|
|
keywords should be written in lowercase.</p>
|
|
|
|
<p style="margin-left:11%; margin-top: 1em">Options in
|
|
<i>nanorc</i> files take precedence over nano’s
|
|
defaults, and command-line options override <i>nanorc</i>
|
|
settings. Also, options that do not take an argument are
|
|
unset by default. So using the <b>unset</b> command is only
|
|
needed when wanting to override a setting of the
|
|
system’s <i>nanorc</i> file in your own <i>nanorc</i>.
|
|
Options that take an argument cannot be unset.</p>
|
|
|
|
<p style="margin-left:11%; margin-top: 1em">Quotes inside
|
|
the <i>characters</i> parameters below should not be
|
|
escaped. The last double quote on the line will be seen as
|
|
the closing quote.</p>
|
|
|
|
<p style="margin-left:11%; margin-top: 1em">The supported
|
|
commands and arguments are: <b><br>
|
|

|
|
|
|
<p style="margin-left:15%;">Make Ctrl+Right and Ctrl+Delete
|
|
stop at word ends instead of beginnings.</p>

|
|
<p style="margin-left:11%;"><b>set
|
|
allow_insecure_backup</b></p>
|
|
|
|
<p style="margin-left:15%;">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.</p>
|
|
|
|
<p style="margin-left:11%;"><b>set atblanks</b></p>
|
|
|

|
|
|
|
<p style="margin-left:15%;">Automatically indent a newly

previous line (or as the next line if the previous line is
|
|
the beginning of a paragraph).</p>
|

|
|
<p style="margin-left:11%;"><b>set backup</b></p>
|
|
|
|
<p style="margin-left:15%;">When saving a file, create a

|
|
<i>directory</i></p>

<p style="margin-left:15%;">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 <b>set
|
|
backup</b> or <b>--backup</b> or <b>-B</b>. The uniquely
|
|
numbered files are stored in the specified
|
|
<i>directory</i>.</p>
|
|
|
|
<p style="margin-left:11%;"><b>set boldtext</b></p>
|
|
|
|
<p style="margin-left:15%;">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 <b>titlecolor</b>,
|
|
<b>statuscolor</b>, <b>keycolor</b>, <b>functioncolor</b>,

|
<b>numbercolor</b>, and <b>selectedcolor</b>.</p>

|
|
"</b><i>characters</i><b>"</b></p>
|
|
|
|
<p style="margin-left:15%;">Set the characters treated as
|
|
closing brackets when justifying paragraphs. This may not
|
|
include blank characters. Only closing punctuation (see
|
|
<b>set punct</b>), optionally followed by the specified
|
|
closing brackets, can end sentences. The default value is
|
|
"<b>"’)>]}</b>".</p>
|
|
|
|
<p style="margin-left:11%;"><b>set breaklonglines</b></p>
|
|
|

|
<b>quickblank</b>.</p>
|
|
|
|
<p style="margin-left:11%;"><b>set cutfromcursor</b></p>
|
|
|
|
<p style="margin-left:15%;">Use

|
|
|

|
<p style="margin-left:15%;">Set the target width for

justifying and automatic hard-wrapping at this <i>number</i>
|
|
of columns. If the value is 0 or less, wrapping will occur

|
|
allowing the wrap point to vary along with the width of the
|
|
screen if the screen is resized. The default value is
|
|
<b>-8</b>.</p>
|
|
|
|
<p style="margin-left:11%;"><b>set functioncolor</b>

|
|
<p style="margin-left:15%;">Draw a vertical stripe at the

|
|
|
|
<p style="margin-left:11%;"><b>set indicator</b></p>
|
|
|
|
<p style="margin-left:15%;">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.</p>
|
|

|
<p style="margin-left:11%;"><b>set jumpyscrolling</b></p>
|
|

<p style="margin-left:15%;">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.)</p>
|
|
|

<p style="margin-left:11%;"><b>set matchbrackets
|
|
"</b><i>characters</i><b>"</b></p>
|
|
|
|
<p style="margin-left:15%;">Specify the opening and closing

|
|
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 <b>set
|
|
stateflags</b>, 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 <b>set constantshow</b> is used, and can be
|
|
toggled on and off with <b>M-C</b>. The state flags are

|
displayed only when <b>set stateflags</b> is used.</p>

|
<p style="margin-left:11%;"><b>set mouse</b></p>
|
|
|
|
<p style="margin-left:15%;">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.</p>
|

|
|
<p style="margin-left:11%;"><b>set nonewlines</b></p>
|
|
|
|
<p style="margin-left:15%;">Don’t automatically add a
|
|
newline when a text does not end with one. (This can cause
|
|
you to save non-POSIX text files.)</p>
|
|
|
|
<p style="margin-left:11%;"><b>set nowrap</b></p>
|
|
|
|
<p style="margin-left:15%;">Deprecated option since it has

|
|
breaklonglines</b> instead.</p>

|
|
|
<p style="margin-left:11%;"><b>set numbercolor</b>
|
|
[<b>bold,</b>][<b>italic,</b>]<i>fgcolor</i><b>,</b><i>bgcolor</i></p>

|
details.</p>
|
|
|
|
<p style="margin-left:11%;"><b>set operatingdir</b>
|
|
<i>directory</i></p>
|
|
|
|
<p style="margin-left:15%;"><b>nano</b> will only read and
|
|
write files inside <i>directory</i> 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.</p>
|
|
|
|
<p style="margin-left:11%;"><b>set positionlog</b></p>
|
|
|
|
<p style="margin-left:15%;">Save the cursor position of
|
|
files between editing sessions. The cursor position is
|
|
remembered for the 200 most-recently edited files.</p>
|
|
|
|
<p style="margin-left:11%;"><b>set preserve</b></p>
|
|
|
|
<p style="margin-left:15%;">Preserve the XON and XOFF keys
|
|
(<b>^Q</b> and <b>^S</b>).</p>
|
|
|
|
<p style="margin-left:11%;"><b>set promptcolor</b>
|
|
[<b>bold,</b>][<b>italic,</b>]<i>fgcolor</i><b>,</b><i>bgcolor</i></p>
|
|
|
|
<p style="margin-left:15%;">Use this color combination for
|
|
the prompt bar. (When this option is not specified, the
|
|
colors of the title bar are used.) See <b>set titlecolor</b>
|
|
for more details.</p>
|
|
|
|
<p style="margin-left:11%;"><b>set punct
|
|
"</b><i>characters</i><b>"</b></p>
|
|
|
|
<p style="margin-left:15%;">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
|
|
<b>brackets</b>), can end sentences. The default value is
|
|
"<b>!.?</b>".</p>
|
|
|
|
<p style="margin-left:11%;"><b>set quickblank</b></p>
|
|
|
|
<p style="margin-left:15%;">Make status-bar messages
|
|
disappear after 1 keystroke instead of after 20. Note that
|
|
option <b>constantshow</b> overrides this. When option
|
|
<b>minibar</b> or <b>zero</b> is in effect,
|
|
<b>quickblank</b> makes a message disappear after 0.8
|
|
seconds instead of after the default 1.5 seconds.</p>
|
|
|
|
<p style="margin-left:11%;"><b>set quotestr
|
|
"</b><i>regex</i><b>"</b></p>
|
|
|
|
<p style="margin-left:15%;">Set the regular expression for
|
|
matching the quoting part of a line. The default value is
|
|
"<b>^([ \t]*([!#%:;>|}]|//))+</b>". (Note
|
|
that <b>\t</b> 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.</p>
|
|
|
|
<p style="margin-left:11%;"><b>set rawsequences</b></p>
|
|
|
|
<p style="margin-left:15%;">Interpret escape sequences
|
|
directly, instead of asking <b>ncurses</b> 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
|
|
<b>nano</b>’s mouse support.</p>
|
|
|
|
<p style="margin-left:11%;"><b>set rebinddelete</b></p>
|
|
|
|
<p style="margin-left:15%;">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.</p>
|
|
|
|
<p style="margin-left:11%;"><b>set regexp</b></p>
|
|
|
|
<p style="margin-left:15%;">Do regular-expression searches
|
|
by default. Regular expressions in <b>nano</b> are of the
|
|
extended type (ERE).</p>
|
|
|
|
<p style="margin-left:11%;"><b>set saveonexit</b></p>
|
|
|
|
<p style="margin-left:15%;">Save a changed buffer
|
|
automatically on exit (<b>^X</b>); don’t prompt.</p>
|
|
|
|
<p style="margin-left:11%;"><b>set scrollercolor</b>
|
|
<i>fgcolor</i><b>,</b><i>bgcolor</i></p>
|
|
|
|
<p style="margin-left:15%;">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
|
|
<b>set titlecolor</b> for more details.</p>
|
|
|
|
<p style="margin-left:11%;"><b>set selectedcolor</b>
|
|
[<b>bold,</b>][<b>italic,</b>]<i>fgcolor</i><b>,</b><i>bgcolor</i></p>
|
|
|
|
<p style="margin-left:15%;">Use this color combination for

selected text. See <b>set titlecolor</b> for more
|
|
details.</p>
|
|

|
<p style="margin-left:11%;"><b>set showcursor</b></p>
|
|
|
|
<p style="margin-left:15%;">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.</p>
|
|
|
|
<p style="margin-left:11%;"><b>set smarthome</b></p>
|
|
|
|
<p style="margin-left:15%;">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.</p>
|
|
|
|
<p style="margin-left:11%;"><b>set softwrap</b></p>
|
|

</h2>
|
|
|
|
|
|
<p style="margin-left:11%; margin-top: 1em">Coloring the
|
|
different syntactic elements of a file is done via regular
|
|
expressions (see the <b>color</b> 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 <b>nano</b>.</p>
|
|
|
|
<p style="margin-left:11%; margin-top: 1em">All regular
|
|
expressions in <b>nano</b> are POSIX extended regular
|
|
expressions. This means that <b>.</b>, <b>?</b>, <b>*</b>,
|
|
<b>+</b>, <b>^</b>, <b>$</b>, and several other characters
|
|
are special. The period <b>.</b> matches any single
|
|
character, <b>?</b> means the preceding item is optional,
|
|
<b>*</b> means the preceding item may be matched zero or
|
|
more times, <b>+</b> means the preceding item must be
|
|
matched one or more times, <b>^</b> matches the beginning of
|
|
a line, and <b>$</b> the end, <b>\<</b> matches the start
|
|
of a word, and <b>\></b> the end, and <b>\s</b> 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: <b>man grep</b>.</p>
|
|
|
|
<p style="margin-left:11%; margin-top: 1em">Each regular
|
|
expression in a <b>nanorc</b> file should be wrapped in
|
|
double quotes (<b>""</b>). 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 (<b>[]</b>).</p>
|
|
|
|
<p style="margin-left:11%; margin-top: 1em">For each kind
|
|
of file a separate syntax can be defined via the following
|
|
commands: <b><br>
|
|
syntax</b> <i>name</i>
|
|
[<b>"</b><i>fileregex</i><b>"</b> ...]</p>
|
|
|
|
<p style="margin-left:22%;">Start the definition of a
|
|
syntax with this <i>name</i>. All subsequent <b>color</b>
|
|
and other such commands will be added to this syntax, until
|
|
a new <b>syntax</b> command is encountered.</p>
|
|
|
|
<p style="margin-left:22%; margin-top: 1em">When
|
|
<b>nano</b> is run, this syntax will be automatically
|
|
activated if the current filename matches the extended
|
|
regular expression <i>fileregex</i>. Or the syntax can be
|
|
explicitly activated by using the <b>-Y</b> or
|
|
<b>--syntax</b> command-line option followed by the
|
|
<i>name</i>.</p>
|
|
|
|
<p style="margin-left:22%; margin-top: 1em">The syntax
|
|
<b>default</b> is special: it takes no <i>fileregex</i>, and
|
|
applies to files that don’t match any syntax’s
|
|
regexes. The syntax <b>none</b> is reserved; specifying it
|
|
on the command line is the same as not having a syntax at
|
|
all.</p>
|
|
|
|
<p style="margin-left:11%;"><b>header

"<b>/*|*/</b>" 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, "<b>#</b>" for Python files. If empty

double quotes are specified, the comment/uncomment function

Besides literal text and/or control codes, the <i>string</i>

<p style="margin-left:11%; margin-top: 1em">Rebinding
|
|
<b>^M</b> (Enter) or <b>^I</b> (Tab) is probably not a good
|
|
idea. Rebinding <b>^[</b> (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 <b>^H</b> (unless <b>--raw</b> is used) because its
|
|
keycode is identical to that of the Backspace key. <br>
