Reblok

Introduction

Reblok build an Abstract Syntax Tree (AST) from a python bytecode (typically found in .pyc files).

Example

>>> from reblok import Parser
>>> add = lambda x: x + 1
>>> print Parser().walk(add)
['function', '<lambda>', [['ret', ('add', ('var', 'x', 'local'), ('const', 1))]], [('x', '<undef>')], None, None, [], {}]
