No experience with ruby but nixpkgs has sections for many languages. See ruby: https://github.com/NixOS/nixpkgs/blob/master/doc/languages-frameworks/ruby.section.md https://github.com/NixOS/nixpkgs/blob/master/doc/languages-f.... Also a quick search on the NixOS wiki gives this: https://nixos.wiki/wiki/Packaging/Ruby https://nixos.wiki/wiki/Packaging/Ruby. This is less packaging related (more nix lang related) but here is my go to resource for functions: https://teu5us.github.io/nix-lib.html https://teu5us.github.io/nix-lib.html. teu5us extracted the builtin/lib function docs and put them on one place saving you from having it split up into multiple manuals. One issue with nix is the content has been written down it’s very inaccessible. It is split up between blog posts, discourse, nixpkgs code comments, the wiki, Reddit, etc. When working on something in nix I’ll frequently have 10+ sources of information. The google-fu needed is strong. My biggest recommendation is to dive into the nixpkgs repo and other public dotfiles as most likely what you are doing has been done.
