"pyclbr" — Python class browser support
***************************************

**Source code:** Lib/pyclbr.py

======================================================================

The "pyclbr" module can be used to determine some limited information
about the classes, methods and top-level functions defined in a
module. The information provided is sufficient to implement a
traditional three-pane class browser. The information is extracted
from the source code rather than by importing the module, so this
module is safe to use with untrusted code. This restriction makes it
impossible to use this module with modules not implemented in Python,
including all standard and optional extension modules.

pyclbr.readmodule(module, path=None)

Read a module and return a dictionary mapping class names to class
descriptor objects. The parameter *module* should be the name of a
module as a string; it may be the name of a module within a
package. The *path* parameter should be a sequence, and is used to
augment the value of "sys.path", which is used to locate module
source code.

pyclbr.readmodule_ex(module, path=None)

Like "readmodule()", but the returned dictionary, in addition to
mapping class names to class descriptor objects, also maps top-
level function names to function descriptor objects. Moreover, if
the module being read is a package, the key "'__path__'" in the
returned dictionary has as its value a list which contains the
package search path.

Class Objects
=============

The "Class" objects used as values in the dictionary returned by
"readmodule()" and "readmodule_ex()" provide the following data
attributes:

Class.module

The name of the module defining the class described by the class
descriptor.

Class.name

The name of the class.

Class.super

A list of "Class" objects which describe the immediate base classes
of the class being described. Classes which are named as
superclasses but which are not discoverable by "readmodule()" are
listed as a string with the class name instead of as "Class"
objects.

Class.methods

A dictionary mapping method names to line numbers.

Class.file

Name of the file containing the "class" statement defining the
class.

Class.lineno

The line number of the "class" statement within the file named by
"file".

Function Objects
================

The "Function" objects used as values in the dictionary returned by
"readmodule_ex()" provide the following attributes:

Function.module

The name of the module defining the function described by the
function descriptor.

Function.name

The name of the function.

Function.file

Name of the file containing the "def" statement defining the
function.

Function.lineno

The line number of the "def" statement within the file named by
"file".
