# nixp-meta

General purpose meta tool for all things nix.

## Currently implemented modules


### PR tracking

Using `nixp-meta track <pr>` on can see which nixpkgs branches a pull requests has reached, to gauge if updating is worth it yet.

### Live PR diffs

If you cannot wait for a PR to be merged, or just want to test it while it's still being worked on, this module is for you.

`nixp-meta add-pr <pr>` Downloads the diff for the specified PR to a folder (default `./patches/PR`)
`nixp-meta update-prs` updates all prs.

Then using below module one can alter nixpkgs to use these patches

```nix
{
  inputs,
  ...
}:
{
  flake = {
    nixpkgs-patched =
      let
        system = "x86_64-linux";
        pkgs = import inputs.nixpkgs { inherit system; };
      in
      pkgs.stdenvNoCC.mkDerivation {
        name = "Nixpkgs with patches from open PRs";
        src = inputs.nixpkgs;
        dontConfigure = true;
        dontBuild = true;
        doCheck = false;
        dontFixup = true;
        installPhase = ''
          cp -r ./ $out
        '';
        patches =
          if builtins.pathExists ../patches then pkgs.lib.filesystem.listFilesRecursive ../patches else [ ];
      };
  };
}
```
