A concise tutorial on building a programming language, also serving as an unofficial ANTLR reference 🌰. This is also where the cyson language originated.
These files are whtoo/How_to_implment_PL_in_Antlr4's own configuration. They tell Claude Code, Codex and OpenCode how to work on this repository, so they are not mods to install elsewhere. Copy one as a starting point and replace the parts that are about this project.
