Rensa DevShell

Minimal devshell implementation using Modules. Inspired by numtide/devshell.

It features the absolute basics, like env variables (dynamic values/eval supported), programs and shell hooks (enterShellCommands). Additional functionality can be added with modules, like Rensa DevTools.

Features

  • fast: due to the NixOS module system it's a bit slower than pkgs.mkShell, but only about 10% (still in the tens of milliseconds range)
  • minimal: only contains the bare minimum, the rest should be added with imported modules
  • straight forward: no toml (like numtide/devshell), no abstractions over Nix (like devenv), just a straight forward Nix lib
