Convert functions into multi-command program breezily.

Project description

The full version of this documentaion is at


Clime lets you convert any module into a multi-command CLI program with zero configuration.

The main features:

  1. It works well with zero configuration. Free you from the configuration hell.

  2. Docstring (i.e., help text) is just configuration. When you finish your docstring, the configuration of aliases and metavars is also finished.

  3. It generates usage for each command 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.

We have a simple script with a docstring here:

# file:

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

        -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 we add this line:


Our CLI program is ready!

$ python twice

$ python --times=3 thrice

It also generates a pretty usage for this script:

$ python --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 shows up in usage manual with --help.

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

It repeats the message.

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

You can find more examples in the clime/examples.

Command describes more about how it works.
