For a while I've been using XFCE's mousepad to write code. Basically notepad but with syntax highlight and line numbers. With all of the fancy tooling you get in IDEs and editors nowadays, it's hard to forget that you really don't need all of that crap to write code. Sure, integrated debuggers and LSP and autocomplete can be very convenient at times, but at the end of the day it's your skill as a programmer that matters, not your tools.
That's only useful in commit messages, issue discussions and stuff like that. Why would the devs even make that execute in source files, where it's all but guaranteed to be a false match??
