patiencediff
############
This package contains the implementation of the ``patiencediff`` algorithm, as
`first described `_ by Bram Cohen.
Like Python's ``difflib``, this module provides both a convenience ``unified_diff``
function for the generation of unified diffs of text files
as well as a SequenceMatcher that can be used on arbitrary lists.
Patiencediff provides a good balance of performance, nice output for humans,
and implementation simplicity.
The code in this package was extracted from the `Bazaar `_
code base.
The package comes with two implementations:
* A Python implementation (_patiencediff_py.py); this implementation only
requires a Python interpreter and is the more readable version of the two
* A C implementation implementation (_patiencediff_c.c); this implementation
is faster, but requires a C compiler and is less readable
Usage
=====
To invoke patiencediff from the command-line::
python -m patiencediff file_a file_b
Or from Python::
>>> import patiencediff
>>> print(''.join(patiencediff.unified_diff(
... ['a\n', 'b\n', 'b\n', 'c\n'],
... ['a\n', 'c\n', 'b\n'])))
