o :aw @sTddlZGdddZddZGdddeZGdd d eZd d ZeZZdS) Nc@s(eZdZdZddZddZddZdS) SubstitutionaG A decorator that performs %-substitution on an object's docstring. This decorator should be robust even if ``obj.__doc__`` is None (for example, if -OO was passed to the interpreter). Usage: construct a docstring.Substitution with a sequence or dictionary suitable for performing substitution; then decorate a suitable function with the constructed object, e.g.:: sub_author_name = Substitution(author='Jason') @sub_author_name def some_function(x): "%(author)s wrote this function" # note that some_function.__doc__ is now "Jason wrote this function" One can also use positional arguments:: sub_first_last_names = Substitution('Edgar Allen', 'Poe') @sub_first_last_names def some_function(x): "%s %s wrote the Raven" cOs"|r|rtd|p ||_}dS)Nz+Only positional or keyword args are allowed) TypeErrorparams)selfargskwargsrr6/usr/lib/python3/dist-packages/matplotlib/docstring.py__init__szSubstitution.__init__cCs|jr t|j|j|_|SN)__doc__inspectZcleandocr)rfuncrrr __call__$szSubstitution.__call__cOs|jj|i|dS)zW Update ``self.params`` (which must be a dict) with the supplied args.
