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)

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).

Nothing else needed unless you want a stripped minimal build snippet or zasm wrapper example.
