You’re getting downvoted (probably because of the mini Vim tutorial in #2) while the author of the post wrote a whole TUI because they didn’t know to change their EDITOR variable.
Learn your tools, people. This is the equivalent of a contractor taping rulers together because they didn’t realize their bag comes with a tape measure.
I feel like this is one of the big things we lose when working completely remote and disconnected: missing out on all these chances to help each other. We don't know the things we don't know.
Imagine OP was going to do a rebase -i, sitting next to a teammate and said, "man, I would do anything to be able to use interactive rebase without having to learn vim", and their teammate turned back and said, "Oh, you can use any editor you want".
git config --global core.editor "vim"But if you already have that and want something specific and different for just git then yeah GIT_EDITOR.
