Project description

An open licensed (MIT) library for performing generating deltas (A.K.A sequences of operations) representing the difference between two sequences of comparable tokens.

Installation: pip install deltas
Repo: http://github.com/halfak/Deltas
Documentation: http://pythonhosted.org/deltas
Note this library requires Python 3.3 or newer

This library is intended to be used to make experimental difference detection strategies more easily available. There are currently two strategies available:

deltas.sequence_matcher.diff(a, b):: A shameless wrapper around difflib.SequenceMatcher to get it to work within the structure of deltas.
deltas.segment_matcher.diff(a, b, segmenter=None):: A generalized difference detector that is designed to detect block moves and copies based on the use of a Segmenter.

Example:

>>> from deltas import segment_matcher, text_split
>>>
>>> a = text_split.tokenize("This is some text.  This is some other text.")
>>> b = text_split.tokenize("This is some other text.  This is some text.")
>>> operations = segment_matcher.diff(a, b)
>>>
>>> for op in operations:
...     print(op.name, repr(''.join(a[op.a1:op.a2])),
...           repr(''.join(b[op.b1:op.b2])))
...
equal 'This is some other text.' 'This is some other text.'
insert ' ' '  '
equal 'This is some text.' 'This is some text.'
delete '  ' ''
