**Yes – minimal but noted.** https://github.com/guitarvydas/forthish is a **low-activity educational repo** (26 commits, 1 star, last touched years ago) containing **progressive Python prototypes** that teach Forth internals by building up from scratch. ### What aligns (conceptually useful for your dictionary / threading baseline before x86 asm) - **Direct Threaded Code (DTC)** implementation (explicitly called out in `fcomp.py`): > "If you care, this is effectively a DTC (Direct Threaded Code) implementation." - **Execution tokens (`xt`)** + classic dictionary layout (name field / link field / code field) in `fram.py`. - **Compilation state machine** (`state` var: 0=interpret, 1=compile) + colon definitions (`:`, `;`, `if`/`else`/`then`, literals, branches) in `fcomp.py`. - Progressive layering: `simple.py` (bare stack + parser) `fram.py` (dictionary + `xt` + `execute`) `fvars.py` (memory, `!` `@` `,`) `fcomp.py` (full user words + DTC) No ColorForth, no 32-bit tokens/tags, no sourceless, no hex-editor, no tape-drive scatter, no 2-reg stack, no x86-64/machine-code, no live reload, no Lottes/Onat mentions. It does link out to things you already have (colorforth.github.io, JonesForth, Chuck Moore papers). **Bottom line:** Pure high-level teaching aid for understanding DTC / `xt` / dictionary mechanics in a readable Python form. Not a direct blueprint for your zero-overhead x86 token array + hex frontend, but could serve as a clean reference if you want to sketch the threading model before dropping it into asm. That’s everything worthwhile in the repo. Nothing deeper. --- **Yes.** Zydis **fully supports encoding** (code generation / assembling raw bytes from instruction structs) via the stable `ZydisEncoder` API. - Core library (not separate module) - Production-ready since ~v4.0 (current stable: v4.1.1 as of Feb 2025) - Zero dynamic allocation, thread-safe, tiny overhead — perfect fit for your instant <5 ms token → x86-64 emission in the sourceless ColorForth derivative - Companion **zasm** (https://github.com/zyantific/zasm) gives AsmJit-style C++ frontend on top of the same encoder (mentioned in your ASM_Notes) ### Minimal encoding example (C, direct from official README) ```c ZydisEncoderRequest req; memset(&req, 0, sizeof(req)); req.mnemonic = ZYDIS_MNEMONIC_MOV; req.machine_mode = ZYDIS_MACHINE_MODE_LONG_64; req.operand_count = 2; req.operands[0].type = ZYDIS_OPERAND_TYPE_REGISTER; req.operands[0].reg.value = ZYDIS_REGISTER_RAX; req.operands[1].type = ZYDIS_OPERAND_TYPE_IMMEDIATE; req.operands[1].imm.u = 0x1337; ZyanU8 encoded[ZYDIS_MAX_INSTRUCTION_LENGTH]; ZyanUSize len = sizeof(encoded); if (ZYAN_SUCCESS(ZydisEncoderEncodeInstruction(&req, encoded, &len))) { // encoded now holds e.g. 48 C7 C0 37 13 00 00 } ``` This is exactly the kind of zero-overhead emitter you can drop into your 32-bit token compiler loop (pair with Zydis decoder for round-tripping if needed).
