A set of project templates for Nix-powered development. Aiming to align with latest best practices in an opinionated way.

This project includes a collection of flake.nix templates for projects of different languages. Each playground provides

• nix develop for development environment.
• nix build for production build and packaging.
• nix fmt for code formatting.

Recommended to be used with direnv and nix-direnv.

$ nix flake init --template github:SharzyL/flakae#cpp_cmake

or

$ nix flake new --template github:SharzyL/flakae#cpp_cmake ./cpp_cmake

Replace cpp_cmake with the desired template name, which is a directory name in this project root.

To synchronize nixpkgs to the system version (as in ~/.config/nix/registry.json):

./bump.sh

Pre-commit hook that performs format checks

#!/usr/bin/env bash

set -euo pipefail

nix fmt -- --fail-on-change

Pre-commit hook that performs flake checks

#!/usr/bin/env bash
