doc to argparse driven by docopt

Project Description

doc to argparse driven by docopt

|PyPi Status|
|Build Status| |Coverage Status| |Branch Coverage Status|

Define your command line interface (CLI) from a docstring (rather than the
other way around). Because it's easy. It's quick. Painless. Then focus on
what's actually important - using the arguments in the rest of your program.

The problem is that this is not always flexible. Still need all the features of
`argparse`? Now have the best of both worlds... all the extension such as
`argcomplete <>`__ or
`Gooey <>`__ but with the simple syntax of
`docopt <>`__.


.. contents:: Table of contents
:backlinks: top


Latest pypi stable release

.. code:: sh

pip install argopt

Latest development release on github

Pull and install in the current directory:

.. code:: sh

pip install -e git+


The list of all changes is available either on
`Github's Releases <>`__
or on crawlers such as
` <>`__.


Standard `docopt <>`__ docstring syntax applies.
Additionally, some improvements and enhancements are supported, such as type
checking and default positional arguments.

.. code:: python

from argopt import argopt

def main(doc):
parser = argopt(doc, version='0.1.2-3.4')
# parser.print_help()

args = parser.parse_args()
print (args)

if __name__ == '__main__':
doc = '''
Example programme description.
You should be able to do
args = argopt(__doc__).parse_args()
instead of
args = docopt(__doc__)

Usage: [-h | options] <x> [<y>...]

<x> A file.
--anarg=<a> Description here [default: 1e3:int].
-p PAT, --patts PAT Or [default: None:file].
--bar=<b> Another [default: something] should
auto-wrap something in quotes and assume str.
-f, --force Force.

Advanced usage and examples

See the `examples <>`__


.. code:: python

def argopt(doc='', argparser=argparse.ArgumentParser, **_kwargs):
Note that `docopt` supports neither type specifiers nor default
positional arguments. We support both here.

doc : docopt compatible, with optional type specifiers
[default: '':str]
argparser : Argument parser class [default: argparse.ArgumentParser]
version : Version string [default: None:str]
_kwargs : any `argparser` initialiser arguments

out : argparser object (default: argparse.ArgumentParser)

Extension syntax example: [default: 1e3:int].

You should be able to do
parser = argopt(__doc__)
args = parser.parse_args()
instead of
args = docopt(__doc__)

(better) subparser support
(docopt extension) action choices
(docopt extension) action count


To run the testing suite please make sure tox (
is installed, then type ``tox`` from the command line.

Where ``tox`` is unavailable, a Makefile-like setup is
provided with the following command:

.. code:: sh

$ python make alltests

To see all options, run:

.. code:: sh

$ python make
