@ -4,12 +4,15 @@ This repository is a Nix flake packaging the [Zig](https://ziglang.com)
compiler. The flake mirrors the binaries built officially by Zig and
does not build them from source.
Provided packages:
This repository is meant to be consumed primarily as a flake but the
`default.nix` can also be imported directly by non-flakes, too.
* Nightly versions updated daily (`.master.<date>`), starting from version
`0.8.0-dev.1140+9270aae07` dated 2021-02-13, and latest master
(`.master.latest`) for the sake of convenience.
* Release versions.
The flake outputs are documented in `flake.nix` but an overview:
* Default package and "app" is the latest released version
* `packages.<version>` for a tagged release
* `packages.master.<date>` for a nightly release
* `packages.master.latest` for the latest nightly release

### No Flake Support
Import in your project as you would normally (`pkgs.fetchFromGitHub` or
`builtins.fetchgit`). The `default.nix` exposes a `pkgs` argument for possible
pinning of the nixpkgs repository, and a `system` argument which defaults to
`builtins.currentSystem`.
```nix
# It is a good idea to use an exact commit in place of 'main' here.
let
zigf = fetchTarball "https://github.com/mitchellh/zig-overlay/archive/main.tar.gz"
in
# If you're using home-manager
home.packages = [ zigf.master.latest ]; # or any available version
# If you're using NixOS
users.user.<username>.packages = [ zigf.master.latest ]; # or any available version
```
