optnix

optnix is a fast, terminal-based options searcher for Nix module systems.

There are multiple module systems that Nix users use on a daily basis:

• NixOS (the most well-known one)
• Home Manager
• nix-darwin
• flake-parts

These systems can have difficult-to-navigate documentation, especially for options in external modules.

optnix solves that problem, and lets users inspect option values if possible; just like nix repl in most cases, but prettier.
