Working Dev Shells

Reusable Nix flake module that provides Rust and Python development shells via flake-parts.

Features

• Rust - configurable toolchain channel (stable/beta/nightly), extensions, rust-analyzer, bacon, glib, openssl
• Python - Python 3.13, uv2nix-based virtual environment, ruff, ty

Usage

Add to your flake inputs:

{
  inputs = {
    working-devshells.url = "git+https://git.geekiot.tech/geekiot/working-devshells.git";
  };
}

Import the module and enable what you need (flake-parts):

{
  imports = [ inputs.working-devshells.flakeModule ];

  perSystem = { config, ... }: {
    workingDevShells.rust.enable = true;
    workingDevShells.python = {
      enable = true;
      workspaceRoot = ./.;
    };
  };
}

Then enter the shell:

nix develop .#rust
nix develop .#python

Complete usage example

{
  inputs = {
    working-devshells.url = "git+https://git.geekiot.tech/geekiot/working-devshells.git";
    nixpkgs.url = "github:nixos/nixpkgs/nixos-unstable";
    flake-parts.url = "github:hercules-ci/flake-parts";
  };

  outputs =
    inputs:
    inputs.flake-parts.lib.mkFlake { inherit inputs; } {
      systems = inputs.working-devshells.systems;
      imports = [ inputs.working-devshells.flakeModule ];

      perSystem =
        { config, ... }:
        {
          workingDevShells.python = {
            enable = true;
            workspaceRoot = ./.;
          };

          devShells.default = config.devShells.python;
        };
    };
}
