Agrh, argparse! =============== Did you ever say "argh" trying to remember the details of optparse or argparse API? If yes, this package may be useful for you. It provides a very simple wrapper for argparse with support for hierarchical commands that can be bound to modules or classes. Argparse can do it; argh makes it easy. In a nutshell ------------- Here's a list of features that `argh` adds to `argparse`: * mark a function as a CLI command and specify its arguments before the parser is instantiated; * nesed commands made easy: no messing with subparsers (though they are of course used under the hood); * infer agrument type from the default value; * infer command name from function name; * add an alias root command ``help`` for the ``--help`` argument; * enable passing unwrapped arguments to certain functions instead of a `argparse.Namespace` object. `Argh` is fully compatible with `argparse`. You can mix `argh`-agnostic and `argh`-aware code. Just keep in mind that `argh.dispatch` does some extra work that a custom dispatcher may not do. Installation ------------ $ pip install argh Example ------- A very simple application with one command:: @command def echo(text='hello'): print text parser = ArghParser() parser.add_commands([echo]) if __name__ == '__main__': parser.dispatch() The powerful API of `argparse` is also available:: @arg('text', default='hello world', nargs='+', help='The message') def echo(args): print args.text The approaches can be safely combined.
