This is the module that can be imported in a Python program in order to use Pyment with the class PyComment.

PyComment class

Module docstring

This module is used by pyment module and is not intended to be used out of Pyment. To use Pyment in your project, you may want to use pyment.PyComment (see above).

DocsTools class

class docstring.DocsTools(style_in='javadoc', style_out='reST', params=None)

This class provides the tools to manage several types of docstring. Currently the following are managed: - ‘javadoc’: javadoc style - ‘reST’: restructured text style compatible with Sphinx - ‘groups’: parameters on beginning of lines (like Google Docs) - ‘google’: the numpy format for docstrings (using an external module) - ‘numpydoc’: the numpy format for docstrings (using an external module)

__init__(style_in='javadoc', style_out='reST', params=None)

Choose the kind of docstring type.

Parameters:
  • style_in (string) – docstring input style (‘javadoc’, ‘reST’, ‘groups’, ‘numpydoc’, ‘google’)

  • style_out (string) – docstring output style (‘javadoc’, ‘reST’, ‘groups’, ‘numpydoc’, ‘google’)

  • params (list) – if known the parameters names that should be found in the docstring.
