deltas 0.3.1

An experimental diff library for generating operation deltas that represent the difference between two sequences of comparable items.

Package Documentation


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

* **Installation:** **TODO**
* **Repo**: ``_
* **Documentation**: ``_
* 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``.

>>> 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:
..., 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 ' ' ''
