# This file is meant to be included into a target to provide an action
# to compute global objects in a component.
#
# To use this, create a gyp target with the following form:
# {
#   'target_name': 'core_global_constructors_idls',
#   'dependencies': [
#     'component_global_objects',
#   ],
#   'variables': {
#     'idl_files': '<(list_of_idl_files)',
#     'global_objects_file': '<(some_dir)/GlobalObjectsComponent.pickle',
#     'global_names_idl_files': [
#       'GlobalName',
#       '<(blink_core_output_dir)/GlobalScopeComponentConstructors.idl',
#       # ...
#     ],
#     'outputs': [
#       '<@(component_global_constructors_generated_idl_files)',
#       '<@(component_global_constructors_generated_header_files)',
#     ],
#   },
#   'includes': ['path/to/this/gypi/file'],
# },
#
# Required variables:
#  idl_files - List of .idl files that will be searched in.
#    This should *only* contain main IDL files, excluding dependencies and
#    testing, which should not appear on global objects.
#  global_objects - Pickle file of global objects.
#  global_names_idl_files - pairs (GlobalName, Constructors.idl)
#  outputs - List of output files.
#    Passed as a variable here, included by the template in the action.
