name: generator
long_name: Generator object
description: |
  This object is returned by [[generator]] and contains a
  generator that is used to transform files from one type to another by
  an executable (e.g. `idl` files into source code and headers).

methods:
  - name: process
    returns: generated_list
    description: |
      Takes an array of files, causes them to be processed and returns an object containing the result
      which can then, for example, be passed into a build target definition.

    varargs:
      name: source
      min_varargs: 1
      type: str | file | custom_tgt | custom_idx | generated_list
      description: sources to process.

    kwargs:
      extra_args:
        type: array[str]
        description: |
          If present, will be used to replace an entry `@EXTRA_ARGS@` in the argument array.

      preserve_path_from:
        type: str
        since: 0.45.0
        description: |
          If given, specifies that the output files need to maintain their directory structure
          inside the target temporary directory. The most common value for this is
          `meson.current_source_dir()`. With this value when a file called
          `subdir/one.input` is processed it generates a file `{target private
          directory}/subdir/one.out` as opposed to `{target private
          directory}/one.out`.

      env:
        type: env | array[str] | dict[str]
        since: 1.3.0
        description: |
          environment variables to set, such as
          `{'NAME1': 'value1', 'NAME2': 'value2'}` or `['NAME1=value1', 'NAME2=value2']`,
          or an [[@env]] object which allows more
          sophisticated environment juggling.

      depends:
        type: array[build_tgt | custom_tgt | custom_idx | program]
        since: 1.12.0
        description: |
          An array of build targets that must be built before attempting to run this
          generator against the source files. This extends the `depends` value of the
          generator to be run.
