zig

Getting Started

Use the version attribute to select the Zig compiler from zig-overlay and the matching ZLS (Zig Language Server) release:

languages.zig = {
  enable = true;
  version = "0.15.1";
};

This will automatically:

  • Use the specified Zig version from zig-overlay
  • Install the corresponding ZLS version (e.g., version “0.15.1” uses ZLS 0.15.0)

Add the required inputs before starting the environment. For the example above:

devenv inputs add zig-overlay github:mitchellh/zig-overlay --follows nixpkgs
devenv inputs add zls github:zigtools/zls/0.15.0 --follows nixpkgs --follows zig-overlay

For Zig 0.16.0, use version = "0.16.0" and add ZLS with devenv inputs add zls github:zigtools/zls/0.16.0 --follows nixpkgs. ZLS 0.16 uses its own zig-flake input instead of zig-overlay. Setting languages.zig.lsp.enable = false disables ZLS and removes the need for the zls input.

Alternatively, you can manually specify packages:

languages.zig = {
  enable = true;
  package = pkgs.zig;
  lsp.package = pkgs.zls;
};
