parser.sx parse-toggle-cmd: when seeing 'toggle .foo for', peek the following two tokens. If they are '<ident> in', it is a for-in loop and toggle does NOT consume 'for' as a duration clause. Restores the trailing for-in to the command list. parser.sx parse-on (handler modifiers): recognize 'throttled at <ms>' and 'debounced at <ms>' as handler modifiers. Captured as :throttle / :debounce kwargs in the on-form parts list. compiler.sx emit-on: pre-extract :throttle / :debounce from parts via new _strip-throttle-debounce helper before scan-on, then wrap the built handler with (hs-throttle! handler ms) or (hs-debounce! handler ms). runtime.sx: hs-throttle! — closure with __hs-last-fire timestamp, fires immediately and drops events arriving within ms of the last fire. hs-debounce! — closure with __hs-timer, clears any pending timer and schedules a new setTimeout(handler, ms) so only the last burst event fires. Both formerly-architectural skips now pass: - "toggle does not consume a following for-in loop" - "throttled at <time> drops events within the window" Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

HS Conformance Scoreboard
Live tally for plans/hs-conformance-to-100.md. Update after every cluster commit.
Baseline: 1213/1496 (81.1%) initial scrape
Snapshot: 1496/1514 upstream sync 2026-05-08 (+18 new upstream tests)
Conformance: 1496/1496 (100.0%) on counted tests; 18 documented architectural skips
Wall: 26m17s sequential (8 batches × 200) via tests/hs-run-batched.js
Target: 1514/1514 — clear the 18 skip list (in progress)
Note: full-suite single-process is unreliable due to JIT cache saturation;
use hs-run-batched.js (fresh kernel per batch) for deterministic numbers.
Skip list (18 — work to do)
| Skip | Reason | Estimated work |
|---|---|---|
Tokenizer-stream API (13) — matchToken, matchTokenType, matchOpToken, matchAnyToken*, peekToken, consumeUntil, consumeUntilWhitespace, pushFollow/popFollow, pushFollows/popFollows, clearFollows/restoreFollows, lastMatch, lastWhitespace |
Upstream exposes a streaming token API on _hyperscript.internals.tokenizer. Our hs-tokenize returns a flat list; parser holds stream state internally as closures. |
Wrap hs-tokenize output in a token-stream object exposed as a primitive. ~1-2 days, mostly mechanical. |
Template-component scope (2) — component reads a feature-level set from an enclosing div on first load, component reads enclosing scope set by a sibling init on first load |
Upstream supports <script type="text/hyperscript-template" component="..."> — HTML-template-based custom elements. Our defcomp is SX-only; no template-component bootstrap. |
Add a <script type="text/hyperscript-template"> registrar alongside the existing script-tag scanner. ~1 day. |
Toggle parser ambiguity (1) — toggle does not consume a following for-in loop |
Parser greedily consumes for x in [...] as toggle .foo for <duration>. Need lookahead to distinguish for <num>ms/s (duration) from for <ident> in <expr> (iteration). |
Targeted parser fix in parse-toggle. ~2-4 hours. |
Throttled-at modifier (1) — throttled at <time> drops events within the window |
Parser doesn't recognize throttled at <duration> as a handler modifier. Currently emits malformed SX (handler body is the literal throttled symbol; time expression dangles outside closure). |
Parser support + runtime hs-throttle! wrapper. ~4 hours. |
Async event dispatch (1) — until event keyword works |
repeat until event click from #x suspends the OCaml kernel waiting for a click that the sync test runner can't dispatch (kernel busy, JS event loop blocked). |
Architectural — requires either yielding to the JS event loop between iterations, or a different test-runner shape that can interleave event injection. ~2-3 days. |
