wasm: three-tier Lumbda to WebAssembly + browser playground
Adds a parallel build of all three Lumbda implementations to WASM, a
single-page playground at www/playground/, and a verified test suite.
Tiers
- Python: Pyodide (CPython-in-WASM) hosting lumbda.py
- C: Emscripten build of c/ (tree-walker + bytecode VM; jit.c
stubbed, gc.c uses its existing no-Boehm fallback)
- Asm: hand-written asm/lumbda.wat — parallel impl to asm/lumbda.s.
Reader, eval (lambda/define/if/cond/let/and/or/quote/set!),
recursion across mutated top-level env, bump allocator with
memory.grow, 24 primitives. ~1200 lines of raw WAT.
SPA (wasm/app/, deployed to www/playground/)
- CodeMirror 6 editor (Scheme highlighting) on left, output on right
- Radios: 4 demos (Mandelbrot, Fib+Ack, Sieve, self-interp meta-eval)
x 4 tiers (Python | C | Asm | All three)
- All-three mode renders the three tier outputs side by side with
per-tier elapsed timing
Tests (38 verified assertions)
- 20 unit (Node): per-tier module loads, eval smoke
- 8 integration (Node): each demo on c+asm WASM byte-matches the
canonical native Python run
- 10 functional (Playwright headless Chromium): page mounts, every
demo runs on every tier, all-three renders
Makefile
- Root targets: wasm-build, wasm-test, wasm-test-fn, wasm-serve,
wasm-deploy, wasm-clean
- wasm/Makefile orchestrates the three tier builds; deploy copies
dist/ into www/playground/
Asm tier notes
- WAT linear symbol intern + linear env lookup is MOAD-0001 at scale;
documented in the asm/lumbda.wat header and in the SPA footer. The
demos hit ~30 globals so the linear walks are cheap enough.
- Bump allocator never frees (matches asm/lumbda.s heap discipline);
memory.grow expands by 1 MB chunks. Browser tab tears down at unload.
Toolchain (developer prerequisites)
- Emscripten 6.0.0 via emsdk at ~/git/emsdk
- wabt 1.0.36 at ~/git/wabt
- Playwright for functional tests (symlinked from ~/git/agnt)
