Portfolio & live playground
Runnable examples compiled to WebAssembly: edit PatLang in the browser and the self-hosted compiler (itself running on WASM) compiles and executes it, with performance self-reported by the programs.
PatLang
A multi-paradigm language with a fully self-hosted compiler: the lexer, parser, lowerer, and code generator are written in PatLang and compile themselves. Events, logic facts, objects, functional style, networking, WASM, and a browser playground.
Getting started
Build the runtime, run and compile your first program, tour the language and all six paradigms, and meet the self-hosting pipeline.
Self-hosting: the road to the fixpoint
How PatLang came to compile itself: the staged roadmap from a Rust Stage 0 seed to byte-identical self-compilation, with the runtime library itself expressed as PatLang source.
Control-flow graphs
Basic blocks and jump edges recovered from the compiler's own IR, rendered as SVG by a PatLang tool.
