Eelco Dolstra 89b1dd8dde Fix environment.checkConfigurationOptions
This requires delaying the declaredness check until later, otherwise
we get an infinite recursion querying
environment.checkConfigurationOptions.

Eelco Dolstra 85b69834e7 fixMergeModules shouldn't check whether options are declared 2013-10-29 14:34:39 +01:00

Eelco Dolstra 0afdb1e933 Add option type "str" for unique strings
An annoying and dangerous property of "types.string" is that it merges
multiple definitions by concatenating them, which almost never
produces a sensible result.  (Those options for which it does make
sense typically should use "types.lines" instead, and things only work
because the option definitions already end in a newline.)  Of course,
you can use "types.uniq types.string", but that's rather verbose, and
inconsistent with other basic types like "types.int".

Changing the behaviour of "types.string" to be unique by default is
not an option, given the large number of options that use it.  So
instead, we now have "types.str", which is equivalent to "types.uniq
types.string".

Eelco Dolstra adc1b38b85 Add a priority level for overrides in VM tests
Now that overriding fileSystems in qemu-vm.nix works again, it's
important that the VM tests that add additional file systems use the
same override priority.  Instead of using the same magic constant
everywhere, they can now use mkVMOverride.

Eelco Dolstra 3115addf4c Fix nixos-option
In particular, it no longer produces an "infinite recursion" error
when run with no arguments.

Eelco Dolstra 73f32d0375 Show precise error messages in option merge failures
For instance, if time.timeZone is defined multiple times, you now get
the error message:

  error: user-thrown exception: The unique option `time.timeZone' is defined multiple times, in `/etc/nixos/configurations/misc/eelco/x11vnc.nix' and `/etc/nixos/configuration.nix'.

while previously you got:

  error: user-thrown exception: Multiple definitions of string. Only one is allowed for this option.

and only an inspection of the stack trace gave a clue as to what
option caused the problem.

Eelco Dolstra d5047faede Remove uses of the "merge" option attribute
It's redundant because you can (and should) specify an option type, or
an apply function.

Eelco Dolstra 40913958a2 Keep position information for option declarations and definitions
Also, when an option definition fails to type-check, print the file
name of the module in which the offending definition occurs, e.g.

  error: user-thrown exception: The option value `boot.loader.grub.version' in `/etc/nixos/configuration.nix' is not a integer.

Eelco Dolstra 0e333688ce Big cleanup of the NixOS module system
The major changes are:

* The evaluation is now driven by the declared options.  In
  particular, this fixes the long-standing problem with lack of
  laziness of disabled option definitions.  Thus, a configuration like

    config = mkIf false {
      environment.systemPackages = throw "bla";
    };

  will now evaluate without throwing an error.  This also improves
  performance since we're not evaluating unused option definitions.

* The implementation of properties is greatly simplified.

* There is a new type constructor "submodule" that replaces
  "optionSet".  Unlike "optionSet", "submodule" gets its option
  declarations as an argument, making it more like "listOf" and other
  type constructors.  A typical use is:

    foo = mkOption {
      type = type.attrsOf (type.submodule (
        { config, ... }:
        { bar = mkOption { ... };
          xyzzy = mkOption { ... };
        }));
    };

  Existing uses of "optionSet" are automatically mapped to
  "submodule".

* Modules are now checked for unsupported attributes: you get an error
  if a module contains an attribute other than "config", "options" or
  "imports".

* The new implementation is faster and uses much less memory.

This means they're not for end users.  Currently they're filtered from
the manual, but we could include them in a separate section.
