git-interactive-rebase-tool

I've been working on adding diff support to a tool I created a while back for interactive rebases in Git. It's been interesting digging into libgit2 and the Rust bindings. https://github.com/MitMaro/git-interactive-rebase-tool The tool/utility provides an easy interface for managing the interactive rebase TODO file. It's heavily inspired by vim and I have plans to expand the functionality. I had tried a similar tool that was written using Node.js but that seemed like overkill. After ranting about the lack of a good tool, my co-worker at the time challenged me to write it that evening after work. I added to the challenge that I would write it Rust since I had not used the language before and I had heard several good things about it. After hacking away for several hours that evening, I had a working prototype to show at work the next day. S
