minishells

This repo is where I park the Nix/devenv shells I actually use for the different open source organisations I work with. Instead of reinventing a dev environment every time, I plug in system config once and spin up a shell per project.

Requirements

• Nix with flakes enabled
• Optional: direnv + nix-direnv

Usage

Enter the default shell:

nix develop

Enter a specific shell:

nix develop .#cloud-pi-native

List available shells:

nix flake show

Direnv

This repo ships an .envrc that loads the default shell:

direnv allow

To automatically load a specific shell, point direnv at the shell attribute:

use flake .#cloud-pi-native --accept-flake-config --no-pure-eval

Template

If you want to consume these shells from another checkout (or without a local clone), you can init a tiny direnv setup:

nix flake init -t github:shikanime-studio/minishells#default

Then edit .envrc to target the shell you want:

use flake github:shikanime-studio/minishells#cloud-pi-native \
  --accept-flake-config --no-pure-eval

Adding A Shell

Shells live under devenv.shells in [flake.nix](file:///Users/shikanimedeva/Source/Repos/github.com/shikanime-studio/minishells/flake.nix). Most shells import base for common packages and settings, then layer extra languages, packages, env vars, and hooks:

devenv.shells.my-shell = {
  imports = [ base ];

  languages.go.enable = true;

  packages = with pkgs; [
    gnumake
  ];
};

This flake also imports devlib, so shells can reuse devlib.devenvModules.<name> profiles for consistent formatters, hooks, and generators.
