Pretty Path

I wanted a way to display a shorter path in my terminal. So I figured I'd write it in Haskell through a Nix dev shell. The result is a program that you can hook into your shell .*rc file to run each time it renders the prompt. Example outputs:

/some/long/path/when/home/isnt/a/parent/ -> /.../parent/

/home/some/long/path/when/home/is/a/parent/ -> ~/.../parent/

TODO:

• also display repo root if you're in a repo

Info

• Nix + Flakes (via github:srid/haskell-flake) + GHC 9.4
• VSCode + HLS
• fourmolu autoformatting
• Relude as Prelude.
  • .hlint.yaml is from relude
• Devshell commands are provided via just; run just in devshell.

Tips

• Run nix flake update to update all flake inputs.
• Run just fmt in nix shell to autoformat the project. This uses treefmt.
• Run just docs to start Hoogle with packages in your cabal file.
