Reblok

Reblok build an Abstract Syntax Tree (AST) back from python bytecode.

###Requirements:

• byteplay

###Compatility:

• python 2.[5-6] (NOT python 2.7, see Notes bellow)

• Has not been tested with python3,

• Should work with pypy, although some specific opcodes are not handled (see Pypy special opcodes).

###Installation easy_install reblok

or

wget http://devedge.bour.cc/resources/reblok/src/reblok.latest.tar.gz
tar xvf reblok.latest.tar.gz
cd reblok-* && ./setup.py install

Documentation

You can found reblok opcodes documentation at http://devedge.bour.cc/resources/reblok/doc/sources/ast.html

Example

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

Notes

reblok is not compatible with python 2.7 at the moment as JUMP_IF_FALSE and JUMP_IF_TRUE opcodes are replaced by new POP_JUMP_IF_FALSE, POP_JUMP_IF_TRUE, JUMP_IF_FALSE_OR_POP and JUMP_IF_TRUE_OR_POP opcodes.
Will be fixed in a future release.

Not yet handled opcodes:

• POP_JUMP_IF_TRUE (py2.7)
• POP_JUMP_IF_FALSE (py2.7)
• JUMP_IF_FALSE_OR_POP (py2.7)
• JUMP_IF_FALSE_OR_TRUE (py2.7)
