Module github.com/pkg/diff can be used to create, modify, and print diffs.

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

The subpackages provide very fine-grained control over every aspect:
– myers: creates diffs using the Myers diff algorithm.

– ctxt: provides tools to reduce the amount of context in a diff.
– write: provides routines to write diffs in standard formats.

This package contains the source code needed for building packages that
reference the following Go import paths:
