- luarocks-nix: bumped to pass args too, `package_X = callPackage ...`.
It allows to remove the annoying `with self`.
This new version disables tests (because broken) and now emits derivation
with a callPackage in front.
- replaced X.override with lib.overrideLuarocks, it should be used
whenever buildInputs/extraVariables is changed since it impacts the
generated luarocks config.
Once structured attributes are in, it will be easier to have the
luarocks config generated by a hook and we probably will be able to
replace all overrideLuarocks by overrideAttrs.
- moved lua hooks to a specific folder as I foresee to add more
- moved generateLuarocksConfig to lib
- fix getLuaPath
- removed the useless rockspecDir
Goal is to improve separation between packages and utilities.
Can help with autocompletion/navigate nixpkgs faster.
Also it will help standardize how LUA_PATH is exported across packages,
so that one can more easily make lua changes across nixpkgs (for
instance changing where lua modules are installed).
