Library for generating Git-style diff patchsets in Go.

Built to be used in the pure-Go implementation of the Git backend for sourcegraph's go-vcs.

Status: Prototyping. None of the backends produce complete output yet, but the difflib one is closest and least broken.

• Git-style patch headers for each file (are there other styles to support?).
• Bring your own diff algorithm by implementing the Differ interface.
• Includes a few diffing backends:
  • pmezard/go-difflib (default)
  • sergi/go-diff/diffmatchpatch (offsets produced are inconsistent with git diff)
  • mb0/diff (incomplete backend)

Work on this package is sponsored by Sourcegraph.
