uncompyle6

Python byte-code disassembler and source-code converter

Project description

uncompyle6

A native Python bytecode Disassembler, Decompiler, Fragment Decompiler and bytecode library

Introduction

uncompyle6 translates Python bytecode back into equivalent Python source code. It accepts bytecodes from Python version 2.5 to 3.4 or so and has been tested on Python running versions 2.6, 2.7, 3.3, 3.4 and 3.5.

Why this?

What makes this different from other CPython bytecode decompilers? Its ability to deparse just fragments and give source-code information around a given bytecode offset.

I use this to deparse fragments of code inside my trepan debuggers. For that, I need to record text fragments for all bytecode offsets (of interest). This purpose although largely compatible with the original intention is yet a little bit different. See this for more information.

The idea of Python fragment deparsing given an instruction offset can be used in showing stack traces or any program that wants to show a location in more detail than just a line number. It can be also used when source-code information does not exist and there is just bytecode information.

Other parts of the library can be used inside Python for various bytecode-related tasks. For example you can read in bytecode, i.e. perform a version-independent marshal.loads(), and disassemble the bytecode using a version of Python different from the one used to compile the bytecode.

Installation

This uses setup.py, so it follows the standard Python routine:

pip install -r requirements.txt
pip install -r requirements-dev.txt
python setup.py install # may need sudo
# or if you have pyenv:
python setup.py develop

A GNU makefile is also provided so make install (possibly as root or sudo) will do the steps above.

Testing

make check

A GNU makefile has been added to smooth over setting running the right command, and running tests from fastest to slowest.

If you have remake installed, you can see the list of all tasks including tests via remake –tasks

Usage

Run

./bin/uncompyle6 -h
./bin/pydisassemble -h

for usage help

Known Bugs/Restrictions

Python 2 deparsing is probably as solid as the various versions of uncompyle2. Python 3 deparsing is okay but not as solid.
