This module is a wrapper to argparse module. Its goal is to generate a custom and advanced command-line from a formatted dictionary. The sequence of subparsers is not limited but it is not possible to have a (sub)parser that have both subparsers and options. The idea is really to not write dozens or hundreds of lines of code to generate the command-line but to outsource it to a file in a "classic" format (YAML, JSON, ...).

Code is available on Github (http://github.com/fmenabe/python-clg).

Documentation is available on readthedocs (https://clg.readthedocs.org/en/latest/).

• Port code to Python 3 (with compatiblity at least until Python 2.6)

• Add description of parser (via desc keyword).

• Add an iterable and accessible namespace for arguments.
• Change behaviour of parse method (now return a namespace with arguments).
• Set default value for list type to empty list.
• Change behaviour of the execution of an external module. It is no longer a python path of a module in 'sys.path' but directly the path of a file. In addition, keyword 'lib' has be replaced by 'path'.
• Replace '__FILE__' in default value of an option by the directory of the program.
• Update the licence to MIT.

• CommandLine object doesn't take anymore a JSON or YAML file but a dictionary.
• Add documentation.
• Updating setup for PyPi.
