Motivation for this change
  • Means there are no longer two separate setup hooks for Lua packages, with partially-overlapping functionality.
  • Fixes pre-existing issues that came to light here.
Things done
  • Tested using sandboxing (nix.useSandbox on NixOS, or option sandbox in nix.conf on non-NixOS)
  • Built on platform(s)
    • NixOS
    • macOS
    • other Linux distributions
  • Tested via one or more NixOS test(s) if existing and applicable for the change (look inside nixos/tests)
  • Tested compilation of all pkgs that depend on this change using nix-shell -p nix-review --run "nix-review wip"
  • Tested execution of all binary files (usually in ./result/bin/)
  • Determined the impact on package closure size (by running nix path-info -S before and after)
  • Ensured that relevant documentation is up to date
  • Fits CONTRIBUTING.md.

cc @teto @vcunat can one of you two poke ofborg for this? I know from last time it would take me a couple days to do a nix-review for all the builds >.>.

Both prosody tests pass, I've manually tested luakit, and I've tested a handful of buildLuaPackage and buildLuarocksPackage derivations, all have worked fine.

thanks for taking care of this, I remember adjusting LUA_PATH to work with modules that had stuff in strange places but maybe with luarocks that was fixed. Anyway this will definitely needs a few nix-review runs to make sure it works fine/fix whatever needs to be fixed. I am

Odd. I just force-pushed the branch to fix an issue with my change to getPath, but it hasn't updated the PR...

No, I followed the branch link at the top of this PR, and the commit hashes are clearly different. What the hell? I guess I'll try rebasing to master and force-push again to see if that gets github to pick it up =/.

lua*Packages: Consolidate separate setup hooks together
d6f151c 
- Lua packages now consistently use LUA_PATH/LUA_CPATH rather than a mix
  of those and NIX_LUA_PATH/NIX_LUA_CPATH
- Lua libraries are now consistently only added to the search path
variables if:
    1) The library actually has a corresponding directory to search
    2) The library is not already present in the search path
  This should help prevent the search paths from growing overly large
- Fixed bugs in some path helpers
- Changed the affected shell script indentation to 2 spaces; nixpkgs
  shell scripts are inconsistently split between 2 and 4 space
  indentation, but 2 matches better with the Nix expressions, so IMO it
  makes more sense

Nope, that didn't work either.

OK, looks like it was super delayed for some reason.

Did a quick test:

~/nixpkgs$ nix-shell -I nixpkgs=./. -p luajit.pkgs.cjson

[nix-shell:~/nixpkgs]$ echo $LUA_PATH

It works like before. Great work @Shados

Without this patches Lua packages in nix-shell are broken (without manual export of LUA_PATH and LUA_CPATH). @teto / @vcunat can you merge this?
