# diff [![GoDoc](https://godoc.org/github.com/pkg/diff?status.svg)](http://godoc.org/github.com/pkg/diff)

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 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.

This module has not yet reached v1.0;
