diff

Module diff can be used to create, modify, and print diffs.

The top level package, diff, contains convenience functions for the most common uses.

The subpackages provide very fine-grained control over every aspect:

• myers creates diffs using the Myers diff algorithm.
• edit contains the core diff data types.
• ctxt provides tools to reduce the amount of context in a diff.
• write provides routines to write diffs in standard formats.

Contributions are welcome. However, I am not always fast to respond. I apologize for any sadness or frustration that that causes.

Useful background reading about diffs:

• Neil Fraser's website
• Myers diff paper
• Guido Van Rossum's reverse engineering of the unified diff format

This module has not yet reached v1.0. There are two main sticking points; see issues #18 and #19.
