nix-flake-template

Template flake for my own use, if you stumble upon this repo, feel free to use it.

Note

Generative AI has been used in making this flake template.

Features

Easy to drop-in, general-purpose development flake template that comes with:

• configuration for project details
• Packages
• Development shell
• Build, Run and Install with the flake (nix build, nix run, nix profile install .)
• Language templates:
  • Shell
  • Generic (C, C++, etc.)
  • Python
  • Rust
  • Gleam (with gleescript)
  • Go
  • Zig

nix flake clone git+https://codeberg.org/Katacc/nix-flake-template --dest .

Just set your project name in (usually the same as in your Cargo.toml for example), uncomment the technology you are using, declare packages and make sure the build section is correct.

There is also included some extra niceties for rust developing like:

• Naersk
• rust-overlay

You just need to uncomment them and wire them to the inputs.

Then you are ready for developing

  # Direnv and nix-direnv users
  direnv allow

  # Normal devshell users
  nix develop 

  # Build
  nix build

  # Run the app
  nix run

  # If using profiles,
  # You can install the app to your profile
  nix profile install .

Note

The flake will not run without uncommenting one package definition!

Extra info

Rust

If you use the normal rust package definition without naersk, nix build will recompile cargo dependencies each time you run or build through nix, which is fine for production application, but for developing, you probably want to use cargo commands or use naersk

narsk allows the use of cargo cache so nix doesnt need to rebuild everything each time! lucky for you, naersk is allready included as a package definition, just start using it, uncomment the imports and such and include naersk in your inputs

Gleam

The gleam package requires you to commit your gleam packages to the git repo.

gleam deps download
git add build/packages -f

nix run
