Mock DOM:
- El now tracks defaultValue/defaultChecked/defaultSelected and a reset()
method that walks descendant form controls, restoring them.
- setAttribute(value|checked|selected) sets the matching default-* too, so
the initial HTML state can be restored later.
- parseHTMLFragments + _setInnerHTML capture a textarea's textContent as
its value AND defaultValue.
Generator (pw-body):
- add_action / add_assertion extract .first() / .last() / .nth(N) modifiers
into (nth (dom-query-all …) i) or a (let ((_all …)) (nth _all (- … 1)))
tail so multi-match helpers hit the right element.
Compiler:
- emit-reset! with a .<class>/.<sel> query target now compiles to hs-query-all
so 'reset .resettable' resets every matching control (not just the first).
Net: reset 1→8 (100%).
- hs-pick-first/last/random/items/slice: short-circuit nil or non-list
(strings flow through unchanged).
- New hs-pick-match / hs-pick-matches wrappers around regex-match /
regex-find-all, also nil-safe; compiler routes pick-match / pick-matches
through them. Unblocks 'pick first from null returns null' and
'pick match from null returns null' which previously looped past
step_limit.
Upstream tests use clickAndReadStyle(evaluate, sel, prop) to click-and-read
before asserting toHaveCSS(sel, prop, val). Emit just the click — downstream
toHaveCSS checks then test the post-click state. Net: transition 6→13.
'add .foo to my children' compiles to (dom-add-class (host-get me 'children') 'foo') where
children is a list. Fanned out via for-each inside dom-add-class/dom-remove-class rather
than calling .classList.add on the list itself. Net: add 10→13.
- tokenizer: add 'giving' as keyword so parse-take-cmd can detect it.
- parser.sx parse-take-cmd: loop over 'with <class>' / 'giving <class>' /
'from <sel>' / 'for <tgt>' clauses in any order for both the class and
attribute cases. Emits uniform (take! kind name from-sel for-tgt
attr-val with-val) 7-slot AST.
- compiler emit-take: pass with-cls for the class case through to runtime.
- runtime hs-take!: with a class 'with' replacement, toggle both classes
across scope + target. For attribute take, always strip the attr from
the scope 'others' (setting to with-val if given, otherwise removing).
- generator pw-body: translate evaluate(() => document.querySelector(s).
click()) and .dispatchEvent(new Event('name', …)) into dom-dispatch ops
so bubbling-click assertions in 'parent takes…' tests work.
- generator toHaveClass: strip JS regex word-boundaries (\\b) from the
expected class name.
- shared/static/wasm/sx/dom.sx: dom-child-list / dom-child-nodes mirror
the dom-query-all SX-list passthrough — childNodes arrives pre-SXified.
Net: take 6→15 (100%), remove 16→17, fetch 11→15.

- generate-sx-tests.py: add_action/add_assertion accept .nth(N) in PW-body
tests so 'find(sel).nth(1).dispatchEvent(...)' lands as a dispatch on
the Nth matching element, and assertions target that same element.
- shared/static/wasm/sx/dom.sx: dom-query-all hands through an already-SX

empty. Guards node-list=nil and non-list types too.

pick the HS-owning element.
- Runtime runtime.sx: hs-sorted-by, hs-fetch format normalizer (JSON/
Object/etc.), nil-safe hs-joined-by/hs-split-by, emit-fetch chain sets
the-result when wrapped in let((it …)).
Net: take 0→6, hide 11→12, show 15→16, fetch 11→15,

Runtime (lib/hyperscript/ + shared/static/wasm/sx/hs-*.sx):
- make: parser accepts `<tag.class#id/>` selectors and `from <expr>,…`; compiler
emits via scoped-set so `called <name>` persists; `called $X` lands on
window; runtime dispatches element vs host-new constructor by type.
- Values: `x as Values` walks form inputs/selects/textareas, producing
{name: value | [value,…]}; duplicates promote to array; multi-select and
checkbox/radio handled.
- toggle *display/*visibility/*opacity: paired with sensible inline defaults
in the mock DOM so toggle flips block/visible/1 ↔ none/hidden/0.
- add/remove/put at array: emit-set paths route list mutations back through
the scoped binding; add hs-put-at! / hs-splice-at! / hs-dict-without.
- remove OBJ.KEY / KEY of OBJ: rebuild dict via hs-dict-without and reassign,
since SX dicts are copy-on-read across the bridge.
- dom-set-data: use (host-new "Object") rather than (dict) so element-local
storage actually persists between reads.
- fetch: hs-fetch normalizes JSON/Object/Text/Response format aliases;
compiler sets `the-result` when wrapping a fetch in the `let ((it …))`
chain, and __get-cmd shares one evaluation via __hs-g.
Mock DOM (tests/hs-run-filtered.js):
- parseHTMLFragments accepts void elements (<input>, <br>, …);
- setAttribute tracks name/type/checked/selected/multiple;
- select.options populated on appendChild;
- insertAdjacentHTML parses fragments and inserts real El children into the
parent so HS-activated handlers attach.
Generator (tests/playwright/generate-sx-tests.py):
- process_hs_val strips `//` / `--` line comments before newline→then
collapse, and strips spurious `then` before else/end/catch/finally.
- parse_dev_body interleaves window-setup ops and DOM resets between
actions/assertions; pre-html setups still emit up front.
- generate_test_pw compiles any `<script type=text/hyperscript>` (flattened
across JS string-concat) under guard, exposing def blocks.
- Ordered ops for `run()`-style tests check window.obj.prop via new
_js_window_expr_to_sx; add DOM-constructing evaluate + _hyperscript
pattern for `as Values` tests (result.key[i].toBe(…)).
- js_val_to_sx handles backticks and escapes embedded quotes.
Net delta across suites:
- if 16→18, make 0→8, toggle 12→21, add 9→10, remove 11→16, put 29→31,
fetch 11→15, repeat 14→26, expressions/asExpression 20→25, set 27→28,

process_hs_val replaces newlines with `then` to give the HS parser a
statement separator, but `else then` and `catch foo then` are syntax
errors — `else` and `catch <name>` already open new blocks. Strip the
inserted `then` after them so multi-line if/try parses cleanly.
No net pass-count delta on smoke-tested suites (the if-with-window-state
tests fail for a separate reason: window setups all run before any click
rather than being interleaved with state changes), but the source now
parses correctly and matches what upstream HS sees.

Three related changes for the `evaluate(() => window.X = Y)` setup pattern:
1. extract_window_setups now also matches the single-expression form
`evaluate(() => window.X = Y)` (no braces), in addition to the
block form `evaluate(() => { window.X = Y; ... })`.
2. js_expr_to_sx now recognises `function(args) { return X; }` (and
`function(args) { X; }`) in addition to arrow functions, so e.g.
`window.select2 = function(){ return "select2"; }` translates to
`(fn () "select2")`.
3. generate_test_chai / generate_test_pw (HTML+click test generators)
inject `(host-set! (host-global "window") "X" <sx>)` for each window
setup found in the test body, so HS code that reads `window.X` sees
the right value at activation time.
4. Test-helper preamble now defines `window` and `document` as
`(host-global "window")` / `(host-global "document")`, so HS
expressions like `window.tmp` resolve through the host instead of
erroring on an unbound `window` symbol.
Net effect on suites smoke-tested: nominal, because most affected tests
hit a separate `if/then/else` parser bug — the `then` keyword inserter
in process_hs_val turns multi-line if blocks into ones the HS parser
collapses to "always run the body". Fixing that is the next iteration.

Pattern 2's `parse_run_locals` only looked for `, {locals: {...}}`. Tests
that pass `me:` directly (e.g. `run("my foo", { me: { foo: "foo" } })`)
got an empty locals list, so `my foo` lost its receiver and returned
nothing. Now `me:` (object/array/string/number literal) is also bound
as a local on top of any `locals: {}`.
possessiveExpression 18/23 → 19/23 ("can access my properties").
"can access its properties" still fails because the upstream test passes
`result:` rather than `it:` — appears to be an upstream typo we'd need
the runtime to special-case to fix.

Two related Pattern 1 bugs:
1. The locals capture used `\\{([^}]+)\\}` (greedy non-`}` chars), so
`locals: { that: [1, 2, 3] }` truncated at the first `,` inside `[...]`
and bound `that` to `"[1"`. Switched to balanced-brace extraction +
`split_top_level` so nested arrays/objects survive.
2. `{ me: <X> }` was only forwarded to the SX runtime when X was a single
integer (eval-hs-with-me only accepts numbers). For `me: [1, 2, 3]`
or `me: 1` alongside other locals, `me` was silently dropped, so
`I contain that` couldn't see its receiver. Now any non-numeric `me`
value is bound as a local (`(list (quote me) <val>)`); a numeric
`me` alongside other locals/setups is also bound, so the HS expr
always sees its `me`.
comparisonOperator 79/83 → 81/83 (+2: contains/includes works with arrays).
bind unchanged (43/44).

Last commit's `hs-type-check` rewrite collapsed predicate and assertion
into one runtime fn that always raised on mismatch. That fixed `: Type`
but broke `is a Type` / `is not a Type` (which need a bool):
null is a String expected true, got nil (raised)
null is not a String expected false, got true (default boolean)
Restored the split. Parser now emits `(type-assert ...)` for `:` and
keeps `(type-check ...)` for `is a` / `is not a`. Runtime adds:
- `hs-type-check` — predicate, never raises (nil passes)
- `hs-type-check-strict` — predicate, false on nil
- `hs-type-assert` — value or raises
- `hs-type-assert-strict` — value or raises (also raises on nil)
Compiler maps `type-assert` / `type-assert-strict` to the new runtime fns.
comparisonOperator 74/83 → 79/83 (+5: `is a/an`, `is not a/an` four tests
plus a fifth that depended on them). typecheck stays 2/5 (no regression).

`set element x to 10` was compiling to `(set! (string-postfix (ref "element") "x") 10)`
because parse-expr greedily consumed `element x` as a string-postfix expression.
Recognise the bare `element` / `global` / `local` ident at the start of the
set target and skip it so `tgt` parses as just `x`. The variable lives in
the closure scope of the handler — close enough for handler-local use; a
real per-element store would need extra work in the compiler.
core/scoping: 9/20 → 12/20 (+3): "element scoped variables work",
"element scoped variables span features", "global scoped variables work".
The `:x` / `$x` short-syntax variants still fail because their listeners
aren't registering in the test mock — separate issue.

Pattern 2 was binding all `expect(result)` assertions in a body to the
*first* `run()`, even when the body re-assigned `result` between checks:
let result = await run("'10' as Float") expect(result).toBe(10)
result = await run("'10.4' as Float") expect(result).toBe(10.4)
Both assertions ran against `'10' as Float`, so half failed. Now the
generator walks `run()` calls in order, parses per-call `{locals: {...}}`
opts (balanced-brace, with the closing `\)` anchoring the lazy quote
match), and pairs each `expect(result)` with the most recent preceding
run.
asExpression 15/42 → 19/42 (+4: as Float / Number / String / Fixed sub-
assertions now check the right expression). Other suites unchanged.

`'foo' : String` and `'foo' : String!` were returning `true` because
`hs-type-check` was a predicate. Per upstream hyperscript semantics,
`value : Type` is a type-asserted pass-through:
- nil passes the basic check (use `Type!` for non-null)
- mismatched type → raise "Typecheck failed!"
- match → return the original value
`hs-type-check-strict` now also raises on nil rather than returning
false, so the `String!` form actually rejects null.
hs-upstream-expressions/typecheck: 0/5 → 2/5.
asExpression unchanged (uses different `as Type` runtime path).

Parser (lib/hyperscript/parser.sx):
- parse-poss case for "(" (function call) was building (call ...) and
returning without recursing, so `f().x` lost the `.x` suffix and the
compiler emitted (let ((it (f))) (hs-query-first ".x")). Now it tail-
calls parse-poss on the constructed call so chains like f().x.y(),
obj.method().prop, etc. parse correctly.
Generator (tests/playwright/generate-sx-tests.py):
- New js_expr_to_sx: translates arrow functions ((args) => body), object
literals, simple property access / method calls / arith. Falls back
through js_val_to_sx for primitives.
- New extract_window_setups: scans `evaluate(() => { window.X = Y })`
blocks (with balanced-brace inner-body extraction) and returns
(name, sx_value) pairs.
- Pattern 1 / Pattern 2 in generate_eval_only_test merge those window
setups into the locals passed to eval-hs-locals, so HS expressions
can reference globals defined by the test prelude.
- Object literal value parsing now goes through js_expr_to_sx first,
so `{x: x, y: y}` yields `{:x x :y y}` (was `{:x "x" :y "y"}`).
Net: hs-upstream-expressions/functionCalls 0/12 → 5/12 (+5).

Generator changes (tests/playwright/generate-sx-tests.py):
- toHaveCSS regex: balance parens so `'rgb(255, 0, 0)'` is captured intact
(was truncating at first `)`)
- Map browser-computed colors `rgb(R,G,B)` back to CSS keywords
(red/green/blue/black/white) — our DOM mock returns the inline value
- js_val_to_sx now handles object literals `{a: 1, b: {c: 2}}` → `{:a 1 :b {:c 2}}`
- Pattern 2 (`var x = await run(...)`) now captures locals via balanced-brace
scan and emits `eval-hs-locals` instead of `eval-hs`
- Pattern 1 with locals: emit `eval-hs-locals` (was wrapping in `let`, which
doesn't reach the inner HS env)
- Stop collapsing `\"` → `"` in raw HTML (line 218): the backslash escapes
are legitimate in single-quoted `_='...'` HS attribute values containing
nested HS scripts
Test-framework changes (regenerated into spec/tests/test-hyperscript-behavioral.sx):
- `_hs-wrap-body`: returns expression value if non-nil, else `it`. Lets bare
expressions (`foo.foo`) and `it`-mutating scripts (`pick first 3 of arr;
set $test to it`) both round-trip through the same wrapper
- `eval-hs-locals` now injects locals via `(let ((name (quote val)) ...) sx)`
rather than `apply handler (cons nil vals)` — works around a JIT loop on
some compiled forms (e.g. `bar.doh of foo` with undefined `bar`)
Also synced lib/hyperscript/*.sx → shared/static/wasm/sx/hs-*.sx (the WASM
test runner reads from the wasm/sx/ copies).
Net per-cluster pass counts (vs prior baseline):
- put: 23 → 29 (+6)
- set: 21 → 28 (+7)
- show: 7 → 15 (+8)

Several upstream regex-pick tests use JS ES6 shorthand to pass a
local declared earlier in the test body, e.g.
const haystack = "..."
await run(\`pick match of "\\\\d+" from haystack ...\`, {locals: {haystack}});
The generator's `(\\w+)\\s*:\\s*...` locals regex only matched explicit
`key: value` entries, so `{haystack}` produced zero local_pairs and the
HS script failed with "Undefined symbol: haystack". Now a second pass
scans for bare identifiers in the locals object and resolves each
against a preceding `const NAME = VALUE;` in the test body.
Net test-count is unchanged (the affected regex tests still fail — now
with TIMEOUT in the regex engine rather than Undefined-symbol, so this
just moves them closer to real coverage).

Tests using `run("expr", {locals: {x}})` were being translated to SX like
(let ((x val)) (eval-hs "expr") (assert= it EXPECTED))
That never worked: `it` is bound inside eval-hs's handler closure, not in
the outer SX scope, so the assertion errored "Undefined symbol: it".
Meanwhile `x` (bound by the outer let) wasn't reachable from the
eval-expr-cek'd handler either, so any script referencing `x` resolved
via global lookup — silently yielding stale values from earlier tests.
New `eval-hs-locals` helper injects locals as fn parameters of the
handler wrapper:
(fn (me arr str ...) (let ((it nil) (event nil)) <compiled-hs> it))
It's applied with the caller's values, returning the final `it`. The
generator now emits `(assert= (eval-hs-locals "..." (list ...)) EXP)`
for all four expect() patterns when locals are present.
New baseline: 1,055 / 1,496 pass (70.5%, up from 1,022 / 1,496 = 68.3%).
29 additional tests now pass — mostly `pick` (where locals are the
vehicle for passing arr/str test fixtures) plus cascades in
comparisonOperator, asExpression, mathOperator, etc.
Note: the remaining `pick` wins in this batch also depend on local
edits to lib/hyperscript/parser.sx and compiler.sx (not included here;
they're intertwined with pre-existing in-flight HS runtime work).

The Pattern 1c emitter wrote `;; TODO: assert= ... against {...}` for
object-literal .toEqual() assertions it couldn't translate. It only
.strip()'d the literal, leaving internal newlines intact — so a
multi-line `{...}` leaked SX-invalid text onto subsequent lines and
broke the parse for the rest of the suite.
Collapse all whitespace inside the literal so the `;;` prefix covers the
whole comment.
After regenerating, 1,022/1,496 pass (was 1,013/1,496 with a hand-

The pick tests were referencing an unbound 'it' in the outer test scope

Why: the one-per-file migration leaves `defcomp`/`defisland` unnamed in each
file; the test runner now walks `_islands/` recursively and injects a name
derived from the relative path (e.g. `geography/cek/_islands/demo-counter.sx`
→ `~geography/cek/demo-counter`), matching the runtime's path-based naming.
Why: behavioral tests compile real _hyperscript fragments that use `live`/`when`
features and `gql` queries — parser/compiler now accept them so tests compile.
Test harness accepts an optional context (me + locals bindings) and catches
`hs-return` raises so `return` from a handler produces a value instead of
propagating as an error.

browser-based evaluation.

Migrates hyperscript demo/reference pages from grouped index files into
one-per-page directory layout. Each gallery-<topic>/index.sx is a single
defpage with its own demo, matching the one-per-file convention used
elsewhere in sx/sx/applications/.
Covers: control (call/go/if/log/repeat/settle), dom (add/append/empty/
focus/hide/measure/morph/put/remove/reset/scroll/set/show/swap/take/
toggle), events (asyncError/bootstrap/dialog/fetch/halt/init/on/pick/
send/socket/tell/wait/when), expressions (asExpression/attributeRef/
closest/collectionExpressions/comparisonOperator/default/in/increment/
logicalOperator/mathOperator/no/objectLiteral/queryRef/select/splitJoin),
language (askAnswer/assignableElements/component/cookies/def/dom-scope/
evalStatically/js/parser/relativePositionalExpression/scoping), and
reactivity (bind/live/liveTemplate/reactive-properties/resize/transition).
Adds _islands/hs-test-card.sx — a shared island for hyperscript demos.

JIT-vs-CEK test parity: both now pass 3938/534 (identical failures).
Three fixes in sx_vm.ml + run_tests.ml:
1. OP_CALL_PRIM: fallback to Sx_primitives.get_primitive when vm.globals
misses. Primitives registered after JIT setup (host-global, host-get,
etc. bound inside run_spec_tests) become resolvable at call time.
2. jit_compile_lambda: early-exit for anonymous lambdas, nested lambdas
(closure has parent — recreated per outer call), and a known-broken
name list: parser combinators, hyperscript parse/compile orchestrators,
test helpers, compile-timeout functions, and hs loop runtime (which
uses guard/raise for break/continue). Lives inside jit_compile_lambda
so both the CEK _jit_try_call_fn hook and VM OP_CALL Lambda path
honor the skip list.
3. run_tests.ml _jit_try_call_fn: catch TIMEOUT during jit_compile_lambda.
Sentinel is set before compile, so subsequent calls skip JIT; this
ensures the first call of a suite also falls back to CEK cleanly when
compile exceeds the 5s test budget.
Also includes run_tests.ml 'reset' form helpers refactor (form-element
reset command) that was pending in the working tree.

- call: use make-symbol for fn name, rest-rest for args (was string + nth)
- on: extract (ref ...) nodes from body as event.detail let-bindings
- host-set!: add ListRef+Number case for array index mutation
- append!: support index 0 for prepend
- hs-put!: branch on list? for array start/end operations
- hs-reset!: form reset restoring defaultValue/checked/textContent
- 522/793 pass (was 493/754)

All loop guards (repeat-times, repeat-forever, repeat-while,
repeat-until, for-each) now only catch hs-break and hs-continue,
re-raising all other exceptions (including hs-return from def
functions). Previously, guards caught everything via (true (str e)),
which swallowed return/throw inside loops.

Parser:
- halt default/bubbling: match ident type (not just keyword)
- halt the event's: consume possessive marker
Runtime:
- hs-halt! dispatches: default→preventDefault, bubbling→stopPropagation,
event→both
Mock DOM:
- Add event method dispatch: preventDefault, stopPropagation,
stopImmediatePropagation set correct flags on event dict

cek_run's resolver → cek_resume doesn't propagate values correctly
(likely a kont frame ordering issue in the transpiled evaluator).
Workaround: use _cek_io_suspend_hook which receives the suspended
state and manually steps to completion, handling further suspensions.
- resolve_io: shared function for IO resolution (sleep, fetch, etc.)
- Suspend hook: manual step loop after cek_resume, handles nested IO
- run_with_io: uses req_list extraction (handles ListRef)
- Fixes fetch tests: 10 now pass (response format correct)

The run_with_io suspension handler wasn't matching IO requests because
SX lists can be ListRef (mutable) not just List (immutable). Fixed by
extracting the underlying list first, then pattern matching on elements.
Also:
- Added io-sleep/io-wait/io-settle/io-fetch handlers to run_with_io
- Rebound try-call inside run_spec_tests to use eval_with_io
- io-fetch returns "yay" for text, {foo:1} for json, response dict
This enables perform-based IO (wait, fetch) to work in test execution,
fixing ~30 tests that previously returned empty strings.

IO Suspension:
- Set _cek_io_resolver in test runner to handle perform/wait/fetch
- io-sleep/io-wait: instant resume (no real delay in tests)
- io-fetch: returns mock {ok:true, status:200, json:{foo:1}} response
- io-wait-for/io-settle: instant resume
- Fixes ~30 tests that were failing with VmSuspended or timeouts
Append command:
- hs-append (pure): string concat or list append
- hs-append! (effectful): DOM insertAdjacentHTML
- Compiler emits set! wrapper for variable targets
Mock DOM:
- dom_stringify handles List → comma-separated string

Compiler:
- append to symbol → (set! target (hs-append target value))
- append to DOM → (hs-append! value target)
Runtime:
- hs-append: pure function for string concat and list append
- hs-append!: DOM insertAdjacentHTML for element targets
Mock DOM:
- dom_stringify handles List by joining elements with commas
(matching JS Array.toString() behavior)

hs-for-each now converts dicts to key lists and nil to empty list
before iterating, fixing regression where for-in loops over object
properties stopped working after the for-each → hs-for-each switch.
