Demystifying compilers by writing your own
summary
A small compiler implemented in Elixir translates a Ragnarok/OpenKore macro language into runtime code for the bot system; source code and a live asciinema show it working. It uses a parser built with Elixir parsing tools (no separate tokenization), builds an AST, a symbol table for semantic checks, and applies two concrete optimizations — constant folding and dead-store elimination — before code generation into the target plugin format. The tool compiles, runs in demos, and the repo shows how to add new commands.
