gitwalk: Bulk processing of git repos

Complex systems are usually made up of many components that span at least a few code repositories. And while this is a very good thing, it adds a few extra steps to your workflow. Having to keep several repositories up to date and on the right branches can become a little cumbersome when you need to quickly search for something or automate a minor change across the whole system. This is when gitwalk comes in. gitwalk lets you manipulate multiple repositories at once. It’s the man-in-the-middle that abstracts away the repetitive work and lets you focus on what needs to be done. You select a group of repos using a simple expression and provide an operation to be completed for each one. This may be searching through files or the commit history, running tests and linters or even editing and pushing changes back upstream — whatever you can think of. And it integrates with GitHub. I’ve been working on gitwalk in my spare time over the past few months and today, I’m releasing it as open source.
