Subclasses should also define the following class attributes: * ``name`` a name for this subcommand * ``help`` a help string for argparse to use for this subcommand * ``args`` the parameters to pass to ``parser.add_argument`` The format of the ``args`` should be a sequence of tuples of the form: .. code-block:: python ('argname', dict( metavar='ARGNAME', nargs='+', )) Example: A simple subcommand "foo" might look like this: .. code-block:: python class Foo(Subcommand): name = "foo" help = "performs the Foo action" args = ( ('--yell', dict( action='store_true', help="Make it loud", )), ) def invoke(self, args): if args.yell: print("FOO!") else: print("foo") Then executing ``bokeh foo --yell`` would print ``FOO!`` at the console. cC`sl||_t|ddƒ}xJ|D]B}|d}t|tƒsM|f}n|jj||dŽq"WdS(ut Initialize the subcommand with its parser Args: parser (Parser) : an Argparse ``Parser`` instance to configure with the args for this subcommand.
