+As mentioned above, starship is a shell-agnostic prompt, written in Rust and which can be configured separately from the shell. I decided to configure it here though, since fish is the only shell I use which is compatible with starship.

+I want starship to be able to detect Lisp files, be it CommonLisp or EmacsLisp. Unfortunately, it seems nerd-font doesn’t have any symbol for either language, so I’m just using a lambda character.
