Adds Sx_vm.bytecode_uses_extension_opcodes — an operand-aware
bytecode scanner that walks past CONST u16, CALL_PRIM u16+u8, and
CLOSURE u16+dynamic upvalue descriptors so operand bytes that happen
to be ≥200 don't false-positive as extension opcodes.
jit_compile_lambda calls the scanner on the inner closure's bytecode.
On hit it returns None — the lambda then runs through CEK
interpretation. The VM's dispatch fallthrough still routes the
extension opcodes themselves through the registry; this change just
prevents the JIT from claiming code it has no plan for.
Tests: 7 new foundation cases — pure core eligible, head/middle/
post-CLOSURE detection, CONST + CALL_PRIM + CLOSURE-descriptor false-
positive avoidance. +7 pass vs Phase D baseline, no regressions
across 11 conformance suites.
Loop complete: acceptance criteria 1-4 met. Hand-off to the Erlang
loop — lib/erlang/vm/dispatcher.sx's Phase 9b stub can now be
replaced with a real hosts/ocaml/lib/extensions/erlang.ml consumer.
lib/extensions/ becomes the new home for VM extensions, wired in via
(include_subdirs unqualified). README documents the registration
pattern, opcode-ID range conventions (200-209 guest_vm, 210-219
inline test, 220-229 test_ext, 230-247 ports), and naming rules.
extensions/test_ext.ml is the canonical worked example — two
operand-less opcodes (220 push 42, 221 double TOS) carrying a per-
extension state slot (TestExtState invocation counter). Test_ext.register
called from run_tests.ml at the start of the Phase D suite, on top of
the inline test_reg from earlier suites (disjoint opcode IDs).
Sx_vm.opcode_name now consults extension_opcode_name_ref (forward ref
in the same style as extension_dispatch_ref), so disassemble shows
extension opcodes by name instead of UNKNOWN_n. Registry maintains
name_of_id_table and installs the lookup at module init.
Tests: 5 new foundation cases — primitive resolves test_ext name,
end-to-end bytecode (push + double + return → 84), disassemble shows
"test_ext.OP_TEST_PUSH_42" / "test_ext.OP_TEST_DOUBLE_TOS",
unregistered ext opcodes still fall back to UNKNOWN_n, invocation
counter records the two dispatches. +5 pass vs Phase C baseline, no
regressions across 11 conformance suites.
Registers extension-opcode-id from sx_vm_extensions.ml module init.
Lives downstream of both sx_primitives and sx_vm to avoid a build
cycle. Accepts a string or symbol; returns Integer id when the opcode
is registered, Nil otherwise.
Compilers (lib/compiler.sx) call this to emit extension opcodes by
name. Returning Nil rather than failing on unknown names lets a port's
optimization opt in per-build — missing extensions degrade to slower
correct execution.
Tests: 5 new foundation cases — registered lookup, unknown → nil,
symbol arg, zero-arg + integer-arg rejection. +5 pass vs Phase B
baseline, no regressions across 11 conformance suites.
sx_vm_extension.ml: handler type, extensible extension_state variant,
EXTENSION first-class module signature.
sx_vm_extensions.ml: register / dispatch / id_of_name /
state_of_extension. install_dispatch () runs at module init,
swapping Phase A's stub for the real registry. Rejects out-of-range
opcode IDs (must be 200-247), duplicate IDs, duplicate names, and
duplicate extension names.
Tests: 9 new foundation cases — lookup hits/misses, end-to-end VM
dispatch including opcode composition, all four rejection paths.
+9 pass vs Phase A baseline, no regressions across 11 conformance
suites.
Adds Invalid_opcode of int exception and extension_dispatch_ref forward
ref (default raises Invalid_opcode op), plus the |op when op >= 200 arm
before the catch-all in the bytecode dispatch loop. Partition comment
documents 1-199 core / 200-247 extensions / 248-255 reserved.
Phase B will install the real registry's dispatch into the ref at module
init, replacing this stub.
Tests: 4 new foundation cases (Invalid_opcode for 200/224/247, Eval_error
for 199 to pin the threshold). +4 pass vs baseline, no regressions.
OCaml kernel changes:
sx_types.ml:
- Add l_call_count : int field to lambda type — counts how many times
a named lambda has been invoked through the VM dispatch path.
- Add module-level refs jit_threshold (default 4), jit_compiled_count,
jit_skipped_count, jit_threshold_skipped_count for stats.
Refs live here (not sx_vm) so sx_primitives can read them without
creating a sx_primitives → sx_vm dependency cycle.
sx_vm.ml:
- In the Lambda case of cek_call_or_suspend, before triggering the JIT,
increment l.l_call_count. Only call jit_compile_ref if count >= the
runtime-tunable threshold. Below threshold, fall through to the
existing cek_call_or_suspend path (interpreter-style).
sx_primitives.ml:
- Register jit-stats — returns dict {threshold, compiled, compile-failed,
below-threshold}.
- Register jit-set-threshold! N — change threshold at runtime.
- Register jit-reset-counters! — zero the stats counters.
bin/run_tests.ml:
- Add l_call_count = 0 to the test-fixture lambda construction.
Effect: lambdas only get JIT-compiled after the 4th invocation. One-shot
lambdas (test harness wrappers, eval-hs throwaways, REPL inputs) never enter
the JIT cache, eliminating the cumulative slowdown that the batched runner
currently works around. Hot paths (component renders, event handlers) cross
the threshold within a handful of calls and get the full JIT speed.
Phase 2 (LRU eviction) and Phase 3 (jit-reset! / jit-clear-cold!) follow.
Verified: 4771 passed, 1111 failed in OCaml run_tests.exe — identical to
baseline before this change. No regressions; tiered logic is correct.

Move `hs-prolog-hook` / `hs-set-prolog-hook!` / `prolog` out of
`lib/hyperscript/runtime.sx` into a self-contained plugin file at
`lib/hyperscript/plugins/prolog.sx`. The API surface is preserved —
`lib/prolog/hs-bridge.sx::pl-install-hs-hook!` still calls
`hs-set-prolog-hook!` exactly as before, just resolved to the plugin
file's binding rather than runtime.sx's.
Move the E39 worker stub registration out of `lib/hyperscript/parser.sx`
into `lib/hyperscript/plugins/worker.sx`. The plugin calls
`(hs-register-feature! "worker" ...)` at file load time. Behaviour is
identical — `worker MyWorker ...` raises the same helpful "plugin not
installed" error, just routed through the registry from a separate
file. The pre-existing `behavioral` test for the helpful error
("raises a helpful error when the worker plugin is not installed")
still passes via the new path.
Wire-up:
- OCaml `bin/run_tests.ml`: load `plugins/worker.sx` and
`plugins/prolog.sx` after `runtime.sx`, before `integration.sx`.
- JS `tests/hs-kernel-eval.js`: extend HS module list with
`hs-worker` / `hs-prolog`; add `HS_PLUGINS` resolver branch so the
`hs-` prefix maps to `lib/hyperscript/plugins/`.
- WASM `hosts/ocaml/browser/bundle.sh`: copy plugin files into
`dist/sx/hs-<name>.sx`.
- WASM `hosts/ocaml/browser/compile-modules.js`: add `hs-worker` /
`hs-prolog` to `FILES`, `HS_DEPS`, and `HS_LAZY` so the lazy loader
resolves them on first reference.
- Worker plugin carries a sentinel `(define hs-worker-loaded? true)`
so `extractDefines` indexes it in the module manifest (the lazy
loader skips files with no defines).
Mirrors `shared/static/wasm/sx/hs-{parser,runtime}.sx` are byte-identical
to source; new mirrors `hs-{prolog,worker}.sx` written via sx_write_file.
OCaml: 4545 passed, 1339 failed — matches baseline.
JS: 2591 passed, 2465 failed — matches baseline.
Smoke tests: `(prolog ...)` raises "prolog hook not installed" cleanly,
`(hs-set-prolog-hook! ...)` then `(prolog ...)` returns the hook result,
`(hs-compile "worker MyWorker def noop() end end")` raises the worker
stub error via the registry path.

- parser `empty` no-target → (ref "me") (was bogus (sym "me"))
- parser `halt` modes distinguish: "all"/"bubbling"/"default" halt execution
(raise hs-return), "the-event"/"the event's" only stop propagation/default.
"'s" now matched as op token, not keyword.
- parser `get` cmd: dispatch + cmd-kw list + parse-get-cmd (parses expr with
optional `as TYPE`). Required for `get result as JSON` in fetch chains.
- compiler empty-target for (local X): emit (set! X (hs-empty-like X)) so
arrays/sets/maps clear the variable, not call DOM empty on the value.
- runtime hs-empty-like: container-of-same-type empty value.
- runtime hs-empty-target!: drop dead FORM branch that was short-circuiting
to innerHTML=""; the querySelectorAll-over-inputs branch now runs.
- runtime hs-halt!: take ev param (was free `event` lookup); raise hs-return
to stop execution unless mode is "the-event".
- runtime hs-reset!: type-aware — FORM → reset, INPUT/TEXTAREA → value/checked
from defaults, SELECT → defaultSelected option.
- runtime hs-open!/hs-close!: toggle `open` attribute on details elements
(not just the prop) so dom-has-attr? assertions work.
- runtime hs-coerce JSON: json-stringify dict/list (was str).
- test-runner mock: host-get on List + "length"/"size" (was only Dict);
dom-set-attr tracks defaultChecked / defaultSelected / defaultValue;
mock_query_all supports comma-separated selector groups.
- generator: emit boolean attrs (checked/selected/etc) even with null value;
drop overcautious "skip HS with bare quotes or embedded HTML" guard so
morph tests (source contains embedded <div>) emit properly.

Load sx/sx/geography/cek/ recursively so content/demo/freeze index.sx
pages bind as ~geography/cek/{content,demo,freeze}. Update docs.sx
cek-page dispatch + test-examples cek:content-pages suite to reference
those real names (were stale ~geography/cek/cek-content etc.).
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
Update test-examples.sx to reference the real path-derived names
(~geography/<domain>/<stem>) instead of short aliases, drop the
alias chains in run_tests.ml, and add marshes/_islands loading so
the migrated one-per-file islands resolve. Fix the try-rerender-page
stub in boot-helpers.sx to accept the 3 args its callers pass.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
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.
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.

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)
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
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
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
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)

Parser:
- Reorder toggle style parsing: target before between clause
- Handle "indexed" keyword, "indexed by" syntax
- Use parse-atom (not parse-expr) for between values to avoid
consuming "and" as boolean operator
- Support 3-4 value cycles via toggle-style-cycle
Compiler:
- Add toggle-style-cycle dispatch → hs-toggle-style-cycle!
Runtime:
- Add hs-toggle-style-between! (2-value toggle)
- Add hs-toggle-style-cycle! (N-value round-robin)
Mock DOM:
- Parse CSS strings from setAttribute "style" into style sub-dict

- Add "indexed" to hs-keywords to prevent unit-suffix consumption
Compiler:
- Use map-indexed instead of for-each for indexed for-loops

When innerHTML is set on a mock element, textContent now updates to
match (with HTML tags stripped). Many HS tests do `put "foo" into me`
(which sets innerHTML) then check textContent. Previously textContent
stayed empty because only innerHTML was updated.
Also fixes innerHTML="" to fully detach children from parent.
393 → 408/831 HS tests (+15).
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
Setting innerHTML="" on a mock element now detaches and removes all
children, matching browser behavior. Previously hs-cleanup! (which
sets body.innerHTML="") left stale children attached, causing
querySelector to find elements from prior tests.
Also clears children when textContent is set (browser behavior).
375 → 393/831 HS tests (+18).
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
In a real browser, innerHTML/textContent/value are always strings.
The mock was storing raw SX values (Number, Bool, Nil), causing type
mismatches like "Expected 1, got 1" where the value was correct but
Number 1.0 != String "1".
Now coerces to string on host-set! for innerHTML, textContent, value,
outerHTML, innerText. Fixes 10 increment tests that were doing
`put value into me` with numeric results.
367 → 375/831 HS tests (+8 net, +10 new passes, -2 regressions).
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
The infinite loops in the HS parser are in transpiled native OCaml code,
not in the VM or CEK step loop. Neither step counters (in cek_step_loop,
cek_step, trampoline) nor VM instruction checks caught them because
the loops are in direct OCaml recursion.
Fix: SIGALRM handler raises Eval_error to break out of native loops.
Also sets step_limit flag to catch VM loops. Combined approach handles
both native OCaml recursion (alarm+raise) and VM bytecode (step check).
The alarm+raise can become unreliable after ~13 timeouts in a single
process, but handles the common case well. Reverts the fork-based
approach which lost inter-test state.

Two critical fixes for the mock DOM test runner:
1. host-get returns truthy for DOM method names on mock elements.
dom.sx guards like `(and el (host-get el "setAttribute"))` were
silently skipping setAttribute/getAttribute calls because the mock
dict had no "setAttribute" key. Now returns Bool true for known
DOM method names, fixing hs-activate! → dom-set-attr → dom-get-attr
chain. Also adds firstElementChild, nextElementSibling, etc. as
computed properties.
2. Fork-based per-test timeout (5 seconds). The HS parser has infinite
loops on certain syntax ([@attr], complex put targets). Signal-based
alarm doesn't work reliably in OCaml 5. Fork + waitpid + select
gives hard OS-level timeout protection.
Also adds step_limit/step_count to sx_ref.ml trampoline (currently
unused but available for future CEK-level timeout).
Result: 525/963 total, up from 498. Many more add/remove/toggle/set
tests now pass because hs-activate! actually wires up event handlers.

Add mock DOM layer to run_tests.ml so hyperscript behavioral tests
(spec/tests/test-hyperscript-behavioral.sx) can run in the OCaml test
runner without a browser. Previously these tests required Playwright
which crashed after 10 minutes from WASM page reboots.
Mock DOM implementation:
- host-global, host-get, host-set!, host-call, host-new, host-callback,
host-typeof, host-await — OCaml primitives operating on SX Dict elements
- Mock elements with classList, style, attributes, event dispatch + bubbling
- querySelector/querySelectorAll with #id, .class, tag, [attr] selectors
- Load web/lib/dom.sx and web/lib/browser.sx for dom-* wrappers
- eval-hs function for expression-only tests (comparisonOperator, etc.)
Result: 367/831 HS tests pass in ~30 seconds (was: Playwright crash).

lib/hyperscript/integration.sx — connects compiled hyperscript to DOM:
hs-handler(src) — compile source → callable (fn (me) ...) via eval-expr-cek
hs-activate!(el) — read _="...", compile, execute with me=element
hs-boot!() — scan document for [_] elements, activate all
hs-boot-subtree!(root) — activate within subtree (for HTMX swaps)
Handler wraps compiled SX in (fn (me) (let ((it nil) (event nil)) ...))
so each element gets its own me binding and clean it/event state.
Double-activation prevented via data-hs-active marker.
12 integration tests verify full pipeline: source → compile → eval.
Handlers correctly bind me, support arithmetic, conditionals, sequences,
for loops, and repeat. 3111/3111 full build, zero regressions.

New primitives in sx_primitives.ml:
char-at, char-code, parse-number — string inspection + conversion
regex-match, regex-match?, regex-find-all — PCRE pattern matching
regex-replace, regex-replace-first — PCRE substitution
regex-split — split by PCRE pattern
Uses Re.Pcre (OCaml re library) so regex patterns use the same syntax
as JS RegExp — patterns in .sx files work identically on browser and
