clg 2.3.0

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/).

Release notes

2.3.0 (2016-10-20)

• Add subparsers after args and options for improved behaviour (4c4471c).

• Add a ‘-p/–page’ option to the help command (added by the add_help_cmd parameter) allowing to page the output (8b2d9fd).

• Remove obsolete script for generating bash and zsh completion (b7a06fb).

• Fix a bug that prevented the completion (using argcomplete) to work when print_help is used (d2590f7).

• Fix a bug that prevented paging of the help (behaviour induced by the page_help parameter) when the help option was not defined manually (0a1a0b4).

• Add the completer parameter for options and arguments allowing to manage argcomplete completers (20c8461).

• Update documentation for argcomplete (66ad52a).

2.2.0 (2016-06-09)

• Add a negative_value parameter for parsers allowing to redefine how negatives values are distinguished from options (4c7e7be).

2.1.1 (2016-05-08)

• print_help parameter is not anymore a root parameter but a per command parameter and simulate the use of the –help option if no arguments are supplied (6bee4d9). This allows flexibiliy for (sub)commands that do not require any input.

2.1.0 (2016-05-08)

• Remove empty list for default value when nargs is set to * or + (4102816).

• Allows to add custom actions by updating ACTIONS dictionnary (65d7480).

• Add a page_help action allowing to page help (818383b, f788f35).

• Add the parameter page_help at the root of the configuration allowing to page the help of all commands (by replacing the default help action by the page_help action; 9454f7a).

• Add the parameter print_help at the root of the configuration allowing to print help when no arguments is set (also work for subcommands; 5ea6fe8)

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.

• Allow bultins.

• Drop compatibility to python2.6 (because of dict comprehension).

0.5 (2013-11-25)

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

0.4 (2013-11-14)

• Add description of parser (via desc keyword).

0.3 (2013-08-09)

• Add an iterable and accessible namespace for arguments.

• Change behaviour of parse method (now return a namespace with arguments).

• Set the default value for list type to an empty list.

• Changes the 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 the default value of an option by the directory of the program.

• Update the license to MIT.

0.2 (2013-07-21)

• CommandLine object doesn’t take anymore a JSON or YAML file but a dictionary.

• Add documentation.

• Updating setup for PyPi.
