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
