This is a collection of diff algorithms, to test various combinations.
|
|
|
|
The initial aim was to provide a faster diff implementation for got
|
|
(gameoftrees.org) with a BSD license, at the u2k20 OpenBSD hackathon.
|
|
A side effect could be improving OpenBSD's /usr/bin/diff utility.
|
|
|
|
At the time of writing, this is little more than a playground / benchmark basis
|
|
/ diff algorithm analysis platform. What could be done:
|
|
- add profiling and test series to rate diff algorithm combinations.
|
|
- interface with / merge into got.

The Myers and Patience Diff algorithm implementations found here are based on
|
|
the explanations found in these blog post series:
|
|
https://blog.jcoglan.com/2017/02/12/the-myers-diff-algorithm-part-1/ ff.
|
|
and
|
|
https://blog.jcoglan.com/2017/09/19/the-patience-diff-algorithm/ ff.
|
|
-- possibly the single most comprehensive explanations of these algorithms.
|
|
Many thanks for this valuable door opener!

The source code itself is not based on the code found in those blogs, but
|
|
written from scratch with the knowledge gained.
