process_hs_val stripped `//…` line comments with a naïve regex,
which devoured `https://yyy.xxxxxx.com/…` inside a backtick template
— the 'properly interpolates values 2' fixture was landing with
the HS source truncated at `https:`.
New helper _strip_hs_line_comments walks char-by-char and only
strips `//` / leading-whitespace `--` when not inside `'…'`, `"…"`,
or backticks; respects `\\`-escapes inside strings.

Runtime gains hs-get-selection: prefers window.__test_selection stash,
falls back to real getSelection().toString(). Compiler rewrites
`(ref "selection")` to `(hs-get-selection)`. Generator detects the
createRange + setStart/setEnd + addRange block and emits a single
host-set! on __test_selection with the text slice; sidesteps the need
for a fully propagating DOM range/text-node mock.

Two generator changes: (a) `parse_run_locals` for Pattern 2
(`var R = await run(...)`) now recognises `result: <literal>` in the
opts dict and binds it to `it` so `run("its foo", {result: {foo: "foo"}})`
produces `(eval-hs-locals "its foo" (list (list (quote it) {:foo "foo"})))`.
Also adds the same extraction to Pattern 1 (`expect(run(...)).toBe(...)`).
(b) `_hs-wrap-body` emitted by the generator no longer shadows `it` to
nil — it only binds `event` — so eval-hs-locals's outer `it` binding is
visible inside the wrapped body. `eval-hs` still binds `it` nil at its
own `fn` wrapper so nothing regresses.
Suite hs-upstream-expressions/possessiveExpression: 22/23 → 23/23.
Smoke 0-195: 162/195 unchanged.

Three parts: (a) parser `collect-transitions` recognises `style`
tokens (`*prop`) as a continuation, so
`transition *width from A to B *height from A to B` chains both
transitions instead of dropping the second. (b) Mock `El` class gets
`nextSibling`/`previousSibling` (plus `*ElementSibling` aliases) so
`transition *W of the next <span/>` can resolve the next-sibling
target via host-get. (c) Generator pattern for
`const X = await evaluate(() => { const el = document.querySelector(SEL);
el.dispatchEvent(new Event(NAME, ...)); return ... })`; optionally
prefixed by a destructuring assignment and allowing trailing
`expect(...).toBe(...)` junk because `_body_statements` only splits on
`;` at depth 0.
Remaining `can use initial to transition to original value` needs
`on click N` count-filtered events (same mock-sync block as cluster 13).
Suite hs-upstream-transition: 13/17 → 15/17. Smoke 0-195: 162/195

Three parts: (a) `runtime.sx` hs-hide-one!/hs-show-one! consult a new
`_hs-hide-strategies` dict (and `_hs-default-hide-strategy` override)
before falling through to the built-in display/opacity/etc. cases. The
strategy fn is called directly with (op, el, arg). New setters
`hs-set-hide-strategies!` and `hs-set-default-hide-strategy!`. (b)
`generate-sx-tests.py` `_hs_config_setup_ops` recognises
`_hyperscript.config.defaultHideShowStrategy = "X"`, `delete …default…`,
and `hideShowStrategies = { NAME: function (op, el, arg) { if …
classList.add/remove } }` with brace-matched function body extraction.
(c) Pre-setup emitter handles `__hs_config__` pseudo-name by emitting
the SX expression as-is (not a window.X = Y assignment).
Suite hs-upstream-hide: 12/16 → 15/16. Remaining test
(`hide element then show element retains original display`) needs

Five parts: (a) tests/hs-run-filtered.js `io-wait-event` mock now
registers a one-shot listener on the target element and resumes with
the event, instead of immediately resuming with nil. (b) Added
hs-wait-for-or runtime form carrying a timeout-ms; mock resumes
immediately when a timeout is present (0ms tests). (c) parser
parse-wait-cmd recognises `wait for EV(v1, v2)` destructure syntax,
emits :destructure list on wait-for AST. (d) compiler emit-wait-for
updated for :from/:or combos; a new `__bind-from-detail__` form
compiles to `(define v (host-get (host-get it "detail") v))`, and the
`do`-sequence handler preprocesses wait-for to splice these synthetic
bindings after the wait. (e) generator extracts `detail: ...` from
`CustomEvent` options so dispatched events carry their payload.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
Partial fix. The generator's block-form `evaluate(() => { ... })`
swallowed blocks that weren't window-setup assignments (e.g. `const e =
new Event(...); elem.dispatchEvent(e);`). It now only `continue`s when
at least one window-setup pair was parsed; otherwise falls through to
downstream patterns. Also added a new pattern that recognises the
`evaluate(() => { const e = new Event(...); document.querySelector(SEL)
.dispatchEvent(e); })` shape and emits a `dom-dispatch` op.
Still failing: "at start of", "in a element target", "in a symbol
write" — root cause here is that the inserted-button's hyperscript
handler still isn't activating in the afterbegin / innerHTML paths.
Tracked separately.

`\$window.foo` / `\${window.foo}` couldn't resolve. Two fixes:
(a) compiler.sx: in a dot-chain base position, known globals (window,
document, navigator, location, history, screen, localStorage,
sessionStorage, console) emit `(host-global "name")` instead of a
bare unbound symbol.
(b) generator: `eval-hs-locals` now also sets each binding on
`window.<name>` via `host-set!`, so tests that translated
`window.X = Y` as a local pair still see `window.X` at eval time.

Upstream body helpers often call element methods directly — showModal,
close, focus, blur, reset, remove. Emit dom-dispatch or host-call ops so
tests that rely on these pre-click state changes work.
Net: dialog 9→12 (100%).
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%).
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.
- 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
list unchanged — the bridge often pre-converts NodeLists/arrays to SX
lists, so the host-get 'length' / host-call 'item' loop was returning
empty. Guards node-list=nil and non-list types too.
- tests/hs-run-filtered.js (mock DOM): fnd() understands
':nth-of-type(N)', ':first-of-type', ':last-of-type' by matching the
stripped base selector and returning the correct-indexed sibling.
Covers upstream tests that write 'find("div:nth-of-type(2)")' to
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,
collectionExpressions 13→15 (remaining are a WASM JIT bug on
{…} literals inside arrays).

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,
core/scoping 12→14, when 39→39 (no regression).

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).

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.

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).

dom-set-attr tracks defaultChecked / defaultSelected / defaultValue;
mock_query_all supports comma-separated selector groups.

morph tests (source contains embedded <div>) emit properly.

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

the SX variant has no equivalent). Switch each test to assert against the

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.
Tests with _=\"...\" attribute delimiters were garbled because
HTMLParser interpreted the backslash-quote as content, not delimiters.
Now html.replace('\"', '"') normalizes before parsing.
Fixes ~15 tests across toggle, transition, and other categories
that were previously running with corrupted HS source.

Root cause: sx_browser.ml registered all HTML tags (a, b, i, p, s, u, g, etc.)
as custom special forms. The evaluator's step_eval_list checked custom special
forms BEFORE checking local env bindings. So (let ((a (fn () 42))) (a))
matched the HTML tag <a> instead of calling the local function a.
Fix: skip custom special forms AND render-check when the symbol is bound in
the local env. Added (not (env-has? env name)) guard to both checks in
step-eval-list (spec/evaluator.sx and transpiled sx_ref.ml).
This was the root cause of "[sx] resume: Not callable: nil" — after hs-wait
resumed, calling letrec-bound functions like wait-boot (which is not an HTML
tag) worked, but any function whose name collided with an HTML tag failed.

callable? in boot-helpers.sx checked for "native-fn" but type-of returns
"function" for NativeFn — broke make-spread and all native fn dispatch
in aser. Restore 20 behavioral tests replaced with NOT IMPLEMENTED stubs
by the test regeneration commit. Add host-* platform primitive stubs to
sx_server.ml so boot-helpers.sx loads without errors server-side.

- Compiler: return compiles to (raise (list "hs-return" value))
- Compiler: def wraps body in guard to catch hs-return exceptions
- Compiler: def params extract name from (ref name) nodes
- Test generator: extract <script type="text/hyperscript"> blocks
and compile def functions as setup before tests
- Test generator: add eval-hs-with-me for {me: N} opts
The return mechanism enables repeat-forever with early exit via return.
Direct SX guard/raise works (returns correct value), but the compiled
HS repeat-forever thunk body needs further debugging for full coverage.

- Handle result["foo"] and result.foo property access after eval-hs
- Handle { locals: { x: 5, y: 5 } } opts with nested braces
- Handle { me: N } opts via eval-hs-with-me helper
- Add eval-hs-with-me to test framework for "I am between" tests
- Use host-get for property access on host handles (JSON.parse results)

Parser: skip unit suffix when next ident is a comparison keyword
(starts, ends, contains, matches, is, does, in, precedes, follows).
Fixes "123 starts with '12'" returning "123starts" instead of true.
eval-hs: use hs-compile directly instead of hs-to-sx-from-source with
"return " prefix, which was causing the parser to consume the comparison
as a string suffix.

- eval-hs: new test helper that compiles+evaluates a HS expression and
returns its result. Uses hs-to-sx-from-source with "return " prefix.
- Generator now emits eval-hs calls for expression-only tests
- no suite: 4/5 pass (was 0/5)
- evalStatically: 5/8 pass (was 0/8 stubs)
- pick: 7/7 pass (was 0/7 stubs)
- mathOperator: 3/5 pass (type issues on array concat)
477/831 (57.4%), +69 from session baseline of 408.

- parse_html now captures ALL elements (not just top-level) with
parent-child relationships
- emit_element_setup uses three phases: attributes, DOM tree, activation
- ref() maps positional names (d1, d2) to top-level elements only
- dom-scope: 9→14 (+5), reset: 3→6 (+3), take: 2→3, parser: 2→3
Net 0 due to regressions in dialog/halt/closest (needs investigation).

- Don't insert 'then' inside for-in loop bodies or after 'repeat N times'
(fixes repeat from 1/30 → 5/30)
- Allow HS sources ending with " when they don't contain embedded HTML
(fixes set from 6/25 → 10/25, enables 18 previously-skipped tests)
- Fix assert= argument order: (actual expected), not (expected actual)
(error messages now correctly report Expected/Got)
395 → 402/831 (+7)

- 7 new tests in computed-ho-forms suite: computed with map, reduce,
for-each, nested map, dict creation, signal updates. All pass on
OCaml and WASM sandbox.
- Removed standalone pretext-position-line and pretext-layout-lines
from pretext-demo.sx — now in text-layout library only
- Root cause of island error: pretext-demo.sx had old define with
(reduce + 0 lwid) that the server serialized into component defs,
overriding the library's sum-loop version

- text-layout.sx added to WASM bytecode pipeline (9K compiled)
- Fix multi-list map calls (map-indexed + nth instead of map fn list1 list2)
- pretext-layout-lines and pretext-position-line moved to library exports
- Browser load-sxbc: handle VmSuspended for import, copy library exports
to global_env after module load (define-library export fix)
- compile-modules.js: text-layout in SOURCE_MAP, FILES, and entry deps
- Island uses library functions (break-lines, pretext-layout-lines)
instead of inlining — runs on bytecode VM when exports resolve
Known issue: define-library exports don't propagate to browser global env
yet. The load-sxbc import suspension handler resumes correctly but
bind_import_set doesn't fire. Needs deeper investigation into how the
WASM kernel's define-library registers exports vs how other libraries
(adapter-html, tw) make their exports available.
