User-visible changes
- Cancel button — terminates the running worker. Pyodide's slow mandelbrot
no longer freezes the UI; click cancel and the elapsed counter freezes
at "(cancelled @ NNNN ms)".
- Live ms counter ticks per animation frame while a tier is busy, so the
Pyodide tier's ~5-15 s wait is visible instead of looking hung.
- Restyled to match lumbda.com: chunkfive wordmark, --green: #227842
(light) / #5ec07a (dark), lumbda-logo-green.png, lowercase "lumbda"
everywhere. Pulls fonts/chunkfive locally so the playground stays
self-contained.
Architecture
- All tier evaluations now run inside a Web Worker (wasm/app/worker.mjs)
so the main thread stays responsive. Cancel = worker.terminate(); next
eval respawns a fresh worker.
- Loaders use new URL("./...", import.meta.url) so paths resolve against
the loader file's own location — works identically in window and
worker contexts, no baseURL argument needed.
- C tier Emscripten build flipped to EXPORT_ES6=1; loader uses dynamic
`import()` of the factory module. Integration test updated accordingly.
- Python loader uses `import("pyodide.mjs")` (ES module) instead of
document.createElement, which doesn't exist in workers.
Bug fixes
- Asm tier state leak: running the same demo twice on a cached WASM
instance produced corrupted output (every other cell on row 2+ rendered
as " " instead of the expected shade char). Root cause: top-level eval
passed `global_env` as the env, so closures captured stale globals;
fixed by passing NIL — env_lookup falls back to the CURRENT global_env
via its existing two-pass walk. Multi-run regression added to the
functional test suite.
- fib-ack demo: (ack 3 4) was too heavy for Pyodide (minutes). Cut to
(ack 3 3) + (fib 20) max so every tier finishes in seconds.
Test discipline
- Root `make test-all` now includes `wasm-test`. Adding a language
feature without exercising it on all six implementations is no longer
possible by accident.
- Functional suite: 11 assertions (was 10) — adds asm multi-run stability.
- Integration + unit: still 20 + 8.
