Historian uses git commit hooks to inject itself into Git's commit workflow. Historian checks your commit messages for certain markup tokens. If found, it updates your project's history file, and amends your commit with it, while also stripping out the markup.

Spackle tells your editor about the errors in your code. No more need to visually scan your test output for errors, filenames, and line numbers. Just tell your editor to jump to the next error location.
