A Python 2.5, 2.6, 2.7 byte-code decompiler, written in Python 2.7

'uncompyle2' converts Python byte-code back into equivalent Python source code. It accepts byte-code from Python version 2.5 to 2.7. Additionally, it will only run on Python 2.7.

The generated source is very readable: docstrings, lists, tuples and hashes get pretty-printed.

'uncompyle2' is based on John Aycock's generic small languages compiler 'spark' (http://www.csr.uvic.ca/~aycock/python/) and his prior work on a tool called 'decompyle'. This tool has been vastly improved by Hartmut Goebel http://www.crazy-compilers.com/

# Additional note (3 July 2004, Ben Burton):

This software is no longer available from the original website. It has now become a commercial decompilation service, with no software available for download.

Any developers seeking to make alterations or enhancements to this code should therefore consider these debian packages an appropriate starting point.

# Additional note (5 June 2012):

The decompilation of python bytecode 2.5 & 2.6 is based on the work of Eloi Vanderbeken. bytecode is translated to a pseudo 2.7 python bytecode and then decompiled.

• decompiles Python byte-code into equivalent Python source
• decompiles byte-code from Python version 2.5, 2.6, 2.7
• pretty-prints docstrings, hashes, lists and tuples
• reads directly from .pyc/.pyo files, bulk-decompile whole directories
• output may be written to file, a directory or to stdout
• option for including byte-code disassembly into generated source

For a list of changes please refer to the 'CHANGES' file.

uncompyle2 requires Python 2.7

You may either create a RPM and install this, or install directly from the source distribution.

Creating RPMS:

python setup.py bdist_rpm

If you need to force the python interpreter to eg. pyton2:

python2 setup.py bdist_rpm --python=python2

### Installation from the source distribution:

python setup.py install

To install to a user's home-dir:

python setup.py install --home=<dir>

To install to another prefix (eg. /usr/local)

python setup.py install --prefix=/usr/local

For more information on 'Installing Python Modules' please refer to http://www.python.org/doc/current/inst/inst.html

./uncompyle2.py -h prints usage

./test_pythonlib.py test files and python library

No support for python 3.2

It currently reconstructs most of Python code but probably needs to be tested more thoroughly. All feedback welcome
