I'm curious, what's some user-friendly terminal based tool to say stage only a couple of discontiguous lines from changes in a single file to commit in Git?

I think I've tried the git command line "interactive" mode, and is really painful. I find myself going to an IDE, selecting the line and right-clicking + "stage selected ranges" to achieve that.

Lazygit is incredibly capable for everything (including this). I don't touch the git cli anymore.

Lazygit for a standalone program, or magit for an emacs package (some people use a different editor and just treat emacs+magit as a dedicated git frontend).
