clg 2.0.0

Command-line generator from a dictionary.

This module is a wrapper to argparse module. Its goal is to generate a custom and advanced command-line from a formatted dictionary. As python dictionnaries are easily exportable to configuration files (like YAML or JSON), the idea is to outsource the command-line definition to a file instead of writing dozens or hundreds lines of code.

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

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

Releases notes

2.0.0 (2015-06-25)

• Change behaviour of groups: groups now act like parsers rather than just referencing previously defined options. It breaks files used by previous versions.

• Update design and correct bugs of the help command added by the add_help_cmd keyword.

• Improve control of abbrevations behaviour. When allow_abbrev parameter was activate, it was not possible to concatenate single options or split with an ‘=’ long options. This is now the case.

• Correct a bug with YAML anchors which causes loss of informations (like the short option).

1.1.1 (2015-02-24)

• Correct a bug when using version action.

1.1 (2015-02-17)

• Add a version keyword for options, allowing to use version action.

• Allow an option add_help_cmd in the root of the configuration that automatically add a help command that show the arborescence of all commands with their descriptions.

• Allow the use of argparse.SUPPRESS with __SUPPRESS__ “builtin”.

• Replace the “builtins” __CHOICES__, __MATCH__ and __FILE__ in the help message by the respectives values of those keywords.

• Add the parameter allow_abbrev in parser configuration, controlling abbrevations behaviour (http://bugs.python.org/issue14910).

1.0 (2014-10-28)

• Rewrite module for matching at best argparse.
