Parse a Python file and retrieve classes and methods.
Parse enough of a Python file to recognize class and method
definitions and to find out the superclasses of a class.
The interface consists of a single function:
module is the name of a Python module, path is an optional list of
directories where the module is to be searched. If present, path is
prepended to the system search path sys.path.
The return value is a dictionary. The keys of the dictionary are
the names of the classes defined in the module (including classes
that are defined via the from XXX import YYY construct). The values
are class instances of the class Class defined here.
A class is described by the class Class in this module. Instances
of this class have the following instance variables:
name -- the name of the class
super -- a list of super classes (Class instances)
methods -- a dictionary of methods
file -- the file in which the class was defined
lineno -- the line in the file on which the class statement occurred
The dictionary of methods uses the method names as keys and the line
numbers on which the method was defined as values.
If the name of a super class is not recognized, the corresponding
entry in the list of super classes is not a class instance but a
string giving the name of the super class. Since import statements
are recognized and imported modules are scanned as well, this
shouldn't happen often.
Continuation lines are not dealt with at all and strings may confuse
the hell out of the parser, but it usually works.
