Let you convert any Python module into a multi-command CLI program without any configuration.

Clime

Clime lets you convert any module into a multi-command CLI program without any configuration.

The main features:

1. It works well with zero configuration. Free you from the configuration hell.
2. Docstring is just config. When you finish the docstring, the config of the aliases and metavars are also finished.
3. It generates the usage of each command from the functions automatically.

It is a better choice than the heavy optparse or argparse for most of the CLI tasks.

CLI-ize ME!

Let me show you Clime with an example.

Here we have a simple script with a docstring here:

# file: repeat.py

def repeat(message, times=2, count=False):
    '''It repeats the message.

    options:
        -m=<str>, --message=<str>  The description of this option.
        -t=<int>, --times=<int>
        -c, --count
    '''

    s = message * times
    return len(s) if count else s

After adding this line,

import clime.now

... your CLI program is ready!

$ python repeat.py twice
twicetwice

$ python repeat.py --times=3 thrice
thricethricethrice

And it generates the usage manual:

$ python repeat.py --help
usage: [-t<int> | --times=<int>] [-c | --count] <message>
   or: repeat [-t<int> | --times=<int>] [-c | --count] <message>

If you have a docstring in your function, it also show up in usage manual with --help.

$ python repeat.py repeat --help
usage: [-t<int> | --times=<int>] [-c | --count] <message>
   or: repeat [-t<int> | --times=<int>] [-c | --count] <message>

It repeats the message.

options:
    -m=<str>, --message=<str>  The message.
    -t=<int>, --times=<int>
    -c, --count

You can find more examples in the clime/examples.

This page, Command.parse, describes how Clime parses the arguments.

If you are interesting in the aliases or the metavariables which Clime provides, read Command for more infomation.

Installation

Clime is hosted on two different platforms, PyPI and GitHub.

1. Install from PyPI

   Install Clime from PyPI for a stable version

   $ sudo pip install clime
   

   If you don't have pip, execute

   $ sudo apt-get install python-pip
   

   to install pip on Debian-base Linux distribution.

2. Get Clime from GitHub

   If you want to follow the latest version of Clime, use

   $ git clone git://github.com/moskytw/clime.git
   

   to clone a Clime repository, or download manually from GitHub.

Usage

You have two different ways to use Clime.

1. Insert A Line into Your Source Code

   Just add this line into your source code:

   import clime.now
   

   It is recommended to put the line in the if __name__ == '__main__': block.

2. Use Clime as A Command

   clime is also an executable module. You can use it to convert a module or a stand-alone program temporarily.

   $ python -m clime TARGET
