lua.withPackages only brings packages that have passthru.luaModule, which was not the case of luarocks (because it's built differently than other lua packages). We call toLuaModule on luarocks so that it is brought in a lua.withPackages call
it makes overriding easier, instead of having to know internals to
decide which of `sqlite = prev.luaLib.overrideLuarocks prev.sqlite (drv: {` or
`sqlite = prev.sqlite.overrideAttrs (drv: {` just use the latter
- 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).
