Eelco Dolstra 21358e7ad0 * Support require/imports in top-level anonymous configurations,
i.e. the elements of initModules that are not paths.
* Support a "key" attribute in anonymous configurations to allow
  lazyGenericClosure to distinguish between them.

Nicolas Pierron 88f113d032 * Add a function to replace "pkgs.checker". The function checkModule does a
traversal of all definitions and also check definitions contained inside
  sub-modules.

Nicolas Pierron b15cbb639e Refactor a bit to add names to intermediate computations. Add a cross
temporary result to fetch information from the evaluation to make them
available inside the option declaration.

Add: isNotDefined flag inside the option.

and another module define its value with "mkIf <false>".

buildfarm ("undefined variable `delayPropertiesTemplate'").

Nicolas Pierron bb16a7f08d Replace a counter intuitive behaviour of module evaluations.
- types.nix:
Introduce a new flag named "delayProperties" which define either that
properties should be evaluated (when false) or that they should be delaied
through the type structure.

- properties.nix:
Generalized the delayProperties function to make it work with the iter
functions of option types.

- modules.nix:
Replace evalProperties by a condition based on the value of the
"delayProperties" flag of the option type.  If the flag does not exists or
if it is false, then the system behaves as always.  Otherwise it delays
the properties from the current value to each values contained inside it.

used to convert option sets, provided inside option declarations, to a
module.

Nicolas Pierron 4c43afbaf6 export definitions to be used in conjunctions with extraConfigs. With such
method, properties evaluated at the evaluation time are still on the values
which makes this interresting to use in conjunction with extraConfigs.
The extraConfigs values are merged with the other values and then the
properties gets evaluated.

Thus, we can keep properties like mkOverride with this method.

Nicolas Pierron 33d43ac18b Add extraConfigs attribute inside options. This attribute is used to
insert definitions from an external location.  As opposed to other
defintions, these definitions are always embedded into a list which allow
to add multiple definitions with one module.

!!! This feature _should not_ be used as a new mean to define options.

Nicolas Pierron b0f639844a the tryEval builtin does not have a strict evaluation. Add the toXML
builtin to force the evaluation of the configuration value.  Thus the
success flag returned by tryEval corespond to the success of the
whole evaluation.

Nicolas Pierron fad1b41fe4 externals argumental are now taking precedence over the result of
moduleMerge because we may need to alter the result of the configuration
before using it inside other options.

Nicolas Pierron 0c16b00cbd Replace the traversal of modules:
- Remove handleOptionSets which used option declarations & definitions
in the same set.
- Add a traversal of modules where "config" and "options" are traverse at
the same time.

This allow to have accruate error messages with the incriminated files
playing a role in the error.

This system add a new restriction compare to the previous system:
- A module with no structure (option definitions & option declarations
& require) should not contain any option declarations.  If such module
exists you must convert it to the following form:

{ imports = <content of the require attribute>;
  options = <set of option declarations>;
  config = <set of option definitions>;
}

Nicolas Pierron 37ce2ca949 Handles cases where developers ""cannot"" put their initial modules in
other files.

Imports of imported attribute set are not working anymore because this
feature is hard to maintain and because this a potential source of error.

Imports are only accepted inside named modules where the system has some
control over mutual inclusion.

Michael Raskin b98b622ef0 Fix NixOS evaluation. As I understand, configuration gets added to the list of modules as an attrSet (not as a file name). Just add a trivial check to passthrough such modules.

2009-09-14 20:10:41 +00:00
Nicolas Pierron 1557cfd0c6 split moduleClosure in two parts:
* unifyModuleSyntax: handle all kind of module syntax to convert them into
  a module which has the following form:

  {
    imports = [ <paths> ];
    options = <attribute set of options declarations>;
    config = <attribute set (with properties) of option definitions>;
  }

  This function assume that there is at most one imported attribute set which
  correspond to option declarations.

* moduleClosure: handle a list of module's paths which are converted with
  the previous function to do the closure of the imports with the function
  lazyGenericClosure (which does the same as builtins.genericClosure except
  that it doesn't evaluate the content of modules).  The "key" and "paths"
  attributes are left to be used as debug information in futur
  implementation(s).
