Entry Points

It is possible to use setuptools’ entry points to load commands directly from python packages. A mach entry point is a function which returns a list of files or directories containing mach command providers. e.g.:

def list_providers():
    providers = []
    here = os.path.abspath(os.path.dirname(__file__))
    for p in os.listdir(here):
        if p.endswith('.py'):
            providers.append(os.path.join(here, p))
    return providers

See http://pythonhosted.org/setuptools/setuptools.html#dynamic-discovery-of-services-and-plugins for more information on creating an entry point. To search for entry point plugins, you can call mach.command_util.load_commands_from_entry_point(). e.g.:

load_commands_from_entry_point("mach.external.providers")
