-The theme I use for fish is [[https://github.com/oh-my-fish/theme-bobthefish][bobthefish]], which by default puts a really long
-timestamp to the right of the prompt. I want something shorter, so here is the
-variable to set, using the format specified in ~date(1)~.

-set -g theme_date_format "+%g-%m-%d %H:%M:%S"

+For my fish prompt, I use [[https://starship.rs][starship]], a shell-agnostic prompt. Let’s load it:
+#+begin_src fish
+starship init fish | source
+#+end_src
 
-I also wish to have a kinda different newline prompt, so let’s set it:
-#+BEGIN_SRC fish
-set -g theme_newline_prompt 'λ '

+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.
 
-Finally, let’s set our prompt’s theme to the Nord theme.

+First I’ll modify the default format variable, removing the modules I don’t need.

+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.
