git-wrong-email is a shell script that refuses to let a commit with the wrong email leave the machine. Why the hook that matters most is pre-push, what it costs to install a global hook without switching off every repo's own hooks, and what it still misses.
One day my personal projects started signing commits with the email of the client I work for instead of mine. A GUI git client had rewritten my global config, and nothing warned me.
I have several MacBooks that should share an environment without all of them having the same things. For over a year I handled it with Homebrew scripts, and the scripts failed at exactly that: they didn't know what was on the machine, didn't know what belonged there, and got things wrong without saying so.
I work on several machines, and some of them aren't mine. At the end of the week I need to know what I did on each one, and the answer was spread across dozens of repositories. didwhat is a command that gets it in one step, with nothing to install but a binary.
It was not my memory failing: it was that I never wrote anything down. The context of what I do lives scattered across Jira, Slack, GitHub and my head, and none of those places keeps the whole story. This is why I ended up writing my own app.
