Clize is an argument parser for `Python `_.  You can

use Clize as an alternative to ``argparse`` if you want an even easier way to

create command-line interfaces.

**With Clize, you can:**

* Create command-line interfaces by creating functions and passing them to

  `clize.run`.

* Enjoy a CLI automatically created from your functions' parameters.

* Bring your users familiar ``--help`` messages generated from your docstrings.

* Reuse functionality across multiple commands using decorators.

* Extend Clize with new parameter behavior.

**Here's an example:**

.. code-block:: python

    from clize import run

    def hello_world(name=None, *, no_capitalize=False):

        """Greets the world or the given name.

        :param name: If specified, only greet this person.

        :param no_capitalize: Don't capitalize the given name.

        """

        if name:

            if not no_capitalize:

                name = name.title()

            return 'Hello {0}!'.format(name)

        return 'Hello world!'

    if __name__ == '__main__':

        run(hello_world)

The python code above can now be used on the command-line as follows:

.. code-block:: console

    $ pip install clize

    $ python3 hello.py --help

        Usage: hello.py [OPTIONS] name

        Greets the world or the given name.

        Positional arguments:

          name   If specified, only greet this person.

        Options:

          --no-capitalize   Don't capitalize the given name.

        Other actions:

          -h, --help   Show the help

    $ python3 hello.py

    Hello world!

    $ python3 hello.py john

    Hello John!

    $ python3 hello.py dave --no-capitalize

    Hello dave!
