Eelco Dolstra f3cdf9b477 Make update-mime-database less verbose 2013-10-30 18:47:44 +01:00
Eelco Dolstra 408b8b5725 Add lots of missing option types 2013-10-30 18:47:43 +01:00
Eelco Dolstra 70a2c54527 Strictly check the arguments to mkOption
And fix various instances of bad arguments.

Eelco Dolstra 800f9c2037 Show correct position info for errors in submodules
E.g.

  The unique option `fileSystems./.device' is defined multiple times, in `/etc/nixos/configuration.nix' and `/etc/nixos/foo.nix'.

This requires passing file/value tuples to the merge functions.

Eelco Dolstra 4680af6a93 Add some option types 2013-10-30 14:57:42 +01:00
Eelco Dolstra 862e3dd977 Substitute "types.uniq types.string" -> "types.str" 2013-10-30 14:57:42 +01:00
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 e28ea1239f Fix evaluation of environment.variables 2013-10-28 22:45:57 +01:00
Eelco Dolstra 259f7a93b1 Rename environment.nix -> nix.package 2013-10-28 22:45:57 +01:00
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 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.

Eelco Dolstra 5b8c4d2a7d Get rid of the only use of mkNotdef 2013-10-28 22:45:54 +01:00
Eelco Dolstra 29014a47fb Allow options to be marked as "internal"
This means they're not for end users.  Currently they're filtered from
the manual, but we could include them in a separate section.
