<p style="color: grey"> Python recipe 577784 by <a href="/recipes/users/4178578/">Christoph Burgmer</a> (<a href="/recipes/tags/diff/">diff</a>). </p> <p>A line-based diff that shows two versions side-by-side based on Google's diff_match_patch implementation.</p> <p>Deletions are displayed on the left side, while additions are displayed on the right similar to the diff shown on Wikipedia.</p>

Revision 4. </p> <p>This is a pure Python implementation of the <a href="http://samba.anu.edu.au/rsync/">rsync algorithm</a>. On my desktop (3.0GHz dual core, 7200RPM), best case throughput for target file hash generation and delta generation is around 2.9MB/s. Absolute worst case scenario (no blocks in common) throughput for delta generation is 200KB/s to 300KB/s on the same system.</p> <p>Tested in Python 2.5, 2.6, and 3.1. In 2.7, io.BufferedReader should yield the best throughput. On all other versions use __builtin__.open.</p>

Revision 4. </p> <p>diff shows difference in files in whole lines. Sometimes those lines are very similar, only one or two words changed. This script compares changed lines by characters and highlights actual differences in them.</p>
