About the Project: Natalie is a very early-stage work-in-progress Ruby implementation that compiles Ruby to an executable. It does so by transpiling Ruby to C++ and feeding it to gcc or clang to produce a binary.

About the Parser: We're rebuilding our parser from scratch so we can stop using the ruby_parser gem someday.

My OS: Ubuntu or Manjaro Linux (depending on which machine I'm on) with Gnome running the Dash to Panel extension. My Editor: Neovim with coc.nvim (intellisense), ALE (linting and auto formatting), CtrlP (jump to file), and the Gruvbox theme.
