uncompyle 1.1

Introduction

‘uncompyle’ converts Python byte-code back into equivalent Python source. It accepts byte-code from Python version 2.7 only.

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

‘uncompyle’ may also verify the equivalence of the generated source by by compiling it and comparing both byte-codes.

‘uncompyle’ is based on John Aycock’s generic small languages compiler ‘spark’ (http://www.csr.uvic.ca/~aycock/python/) and his prior work on ‘decompyle’.

Additional note (3 July 2004, Ben Burton):

The original website from which this software was obtained is no longer available. 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.

Features

• decompiles Python byte-code into equivalent Python source

• decompiles byte-code from Python version 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.

Requirements

‘decompile’ requires Python 2.2 or later.

Installation

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

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

python2 setup.py install

Usage

uncompyler -h prints short usage uncompyler –help prints long usage
