JHYY (机会翼游): a self-hosted, statically typed, expression-oriented systems language. The compiler is written in itself and reproduces itself byte-for-byte to a fixed point. The backend is a self-written amd64 emitter — no QBE, no LLVM, no GC, no managed runtime. Native PE/COFF and ELF output, C ABI FFI, no_std, inline asm. MIT.

An experimental programming language.

A tiny, dependency-free scripting language: lexer, parser, tree-walking evaluator and REPL. Built as an AIKit evaluation project, where the process is under test as much as the code. Free personal use under AL-1.1; commercial use under ACL-1.0.

JiHuiYiYou-for-VEX: an embedded target for the JHYY (机会翼游) systems language — compiling to the VEX V5 Brain (ARM Cortex-A9). Every VEX-side unknown becomes a measured value: signed binary format, startup chain, softfp ABI, struct layouts, register conventions, minimal binding surface. Route B emits ARM machine code and links the official SDK.
