Output a patch instead

[sniperrifle2004]

I was wondering if it would be possible for ghc-hare to produce a patch or a diff instead of refactored files.

I don't know enough about this project to answer your question,
but if you are using a VCS (e.g. git), which you should be, creating a patch from the new files is a trivial task:

1. Make sure your repository is clean. Commit or stash any current changes. (Run git status to check)
2. Run HaRe
3. Run git diff > changes.patch to save the diff in changes.patch.
4. (optional) Run git reset --hard to restore your repository and revert the changes.
