This is a fork of python-Levenshtein which also distributes binary wheels for a lot of operating systems and architectures:
- Windows (amd64 and x86)
- OSX (10.6+)
- Linux (x86_64 and i686)
The wheels can be installed with the python-Levenshtein-wheels package on PyPI.
The Levenshtein Python C extension module contains functions for fast computation of
- Levenshtein (edit) distance, and edit operations
- string similarity
- approximate median strings, and generally string averaging
- string sequence and set similarity
It supports both normal and Unicode strings.
Python 2.2 or newer is required; Python 3 is supported.
StringMatcher.py is an example SequenceMatcher-like class built on the top of Levenshtein. It misses some SequenceMatcher's functionality, and has some extra OTOH.
Levenshtein.c can be used as a pure C library, too. You only have to define NO_PYTHON preprocessor symbol (-DNO_PYTHON) when compiling it. The functionality is similar to that of the Python extension. No separate docs are provided yet, RTFS. But they are not interchangeable:
- C functions exported when compiling with -DNO_PYTHON (see Levenshtein.h) are not exported when compiling as a Python extension (and vice versa)
- Unicode character type used with -DNO_PYTHON is wchar_t, Python extension uses Py_UNICODE, they may be the same but don't count on it
gendoc.sh generates HTML API documentation,
you probably want a selfcontained instead of includable version, so run
in ./gendoc.sh --selfcontained. It needs Levenshtein already installed
and genextdoc.py.

This package was long missing from the Python Package Index and available as source checkout only, but can now be found on PyPI again.
We needed to restore this package for Go Mobile for Plone and Pywurfl projects which depend on this.
