komandr 0.1.1

Convert your ordinary functions into cool command-line interfaces!

Komandr is a smart thin wrapper around powerful argparse module lets you build defacto standart command-line interfaces in secondz while providing you all the flexibity.

Example

# example.py

from komandr import *


# straigforward ad-hoc usage
@command
def foo(bar, baz=None):
    print 'foo', bar, baz


# but also it allows you much more tuning
@command(name='cool_command_name')
@arg('baz', '-z', required=True, type=int)
def lame_command_name(foo, bar, baz=1):
    print 'lame_command_name', foo, bar, baz

if __name__ == '__main__':
    main()

Need some help?:

$ python example.py --help
usage: example.py [-h] [-v] {foo,cool_command_name} ...

positional arguments:
  {foo,cool_command_name}

optional arguments:
  -h, --help            show this help message and exit
  -v, --version         show program's version number and exit

Let’s investigate more about foo:

$ python example.py foo --help
usage: example.py foo [-h] --baz BAZ bar

positional arguments:
  bar

optional arguments:
  -h, --help  show this help message and exit
  --baz BAZ

Test foo command:

$ python example.py foo Hello
usage: example.py foo [-h] --baz BAZ bar
example.py foo: error: argument --baz is required

That’s ok now:

$ python example.py foo Hello --baz World
foo Hello World

Cool, eh?

This also shows how flexible and configurable it is:

$ python example.py cool_command_name Hello -z 'Non numeric' World
usage: example.py cool_command_name [-h] --baz BAZ foo bar
example.py cool_command_name: error: argument --baz/-z: invalid int value: 'Non Numeric'

Correct one should be:

$ python example.py cool_command_name Hello -z 2013 World
lame_command_name Hello World 2013

Enjoy!
