vinibispo/ruby.nvim — reverse-engineered prompt

I want to make a small Neovim plugin called ruby.nvim that helps Ruby developers do the common things they do all day without leaving the editor. Build the Lua plugin so that when I’m editing a Ruby file I can run the current file in a terminal, jump between a source file and its matching test or spec file, run the relevant Ruby tests, and try to open or inspect a gem from the current project if that is reasonable.

Please keep it simple and practical, with clean commands like RubyRun, RubyAlternate, RubyTest, and RubyBrowseGem, plus filetype setup for Ruby files. Add helpful messages when something can’t be found instead of crashing. Include basic Neovim help docs and a short README that explains installation, usage, and that modern alternatives may cover some features better. Look up current Neovim Lua plugin docs online if you need to.
