      5 # This file is meant to be included into a target to provide an action
      6 # to compute global objects in a component.
      7 #
      8 # To use this, create a gyp target with the following form:
      9 # {
     10 #   'target_name': 'component_global_objects',
     11 #   'variables': {
     12 #     'idl_files': '<(list_of_idl_files)',
     13 #     'input_files': ['<(some_dir)/GlobalObjectBaseComponent.pickle'],
     14 #     'output_file': '<(some_dir)/GlobalObjectsComponent.pickle',
     15 #   },
     16 #   'includes': ['path/to/this/gypi/file'],
     17 # },
     18 #
     19 # Required variables:
     20 #  idl_files - List of .idl files that will be searched in.
     21 #    This should *only* contain main IDL files, excluding dependencies and
     22 #    testing, which should not define global objects.
     23 #  output_file - Pickle file of output.
     24 #
     25 # Optional variables:
     26 #  input_files - List of input pickle files of global objects in base
     27 #    components. In this case make sure to include a dependencies section
     28 #    in the target to ensure this is generated.
