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:
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)Python 2.7 is supported through decorators.
The python code above can now be used on the command-line as follows:
$ 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
