Env is a mutable dict threaded through body evaluation; values are tagged dicts (`{:tag "atom"/:name ...}`, `{:tag "nil"}`, `{:tag "cons" :head :tail}`, `{:tag "tuple" :elements}`). Numbers pass through as SX numbers. Gotcha: SX's `parse-number` coerces `"1.0"` → integer `1`, so `=:=` can't distinguish `1` from `1.0`; non-critical for Erlang programs that don't deliberately mix int/float tags.

Total eval 130/130; erlang suite 244/244. **Phase 2 complete — Phase 3 (processes, scheduler, receive) is next.** - **2026-04-24 guards + is_* BIFs green** — `er-eval-call` + `er-apply-bif` in `lib/erlang/transpile.sx` wire local function calls to a BIF dispatcher. Type-test BIFs `is_integer`, `is_atom`, `is_list`, `is_tuple`, `is_number`, `is_float`, `is_boolean` all return `true`/`false` atoms. Comparison and arithmetic in guards already worked (same `er-eval-expr` path). 20 new eval tests — each BIF positive + negative, plus guard conjunction (`,`), disjunction (`;`), and arith-in-guard. Total eval 95/95; erlang suite 209/209.

On no match, `(shift k ...)` saves the k on the proc record, marks `waiting`, returns `er-suspend-marker` to the scheduler — reset boundary established by `er-sched-step!`. Scheduler loop `er-sched-run-all!` pops runnable pids and calls either `(reset ...)` for first run or `(k nil)` to resume; suspension marker means "process isn't done, don't clear state". `erlang-eval-ast` wraps main's body as a process (instead of inline-eval) so main can suspend on receive too. Queue helpers added: `er-q-nth`, `er-q-delete-at!`. 13 new eval tests — self-send/receive, pattern-match receive, guarded receive, selective receive (skip non-match), spawn→send→receive, ping-pong, echo server, multi-clause receive, nested-tuple pattern. Total eval 156/156; suite 309/309. Deadlock detected if main never terminates. - **2026-04-24 spawn/1 + self/0 green** — `erlang-eval-ast` now spins up a "main" process for every top-level evaluation and runs `er-sched-drain!` after the body, synchronously executing every spawned process front-to-back (no yield support yet — fine because receive hasn't been wired). BIFs added in `lib/erlang/runtime.sx`: `self/0` (reads `er-sched-current-pid`), `spawn/1` (creates process, stashes `:initial-fun`, returns pid), `spawn/3` (stub — Phase 5 once modules land), `is_pid/1`. Pids added to `er-equal?` (id compare) and `er-type-order` (between strings and tuples); `er-format-value` renders as ``. 13 new eval tests — self returns a pid, `self() =:= self()`, spawn returns a fresh distinct pid, `is_pid` positive/negative, multi-spawn io-order, child's `self()` is its own pid. Total eval 143/143; runtime 39/39; suite 296/296.

Process records with `:pid`, `:mailbox` (queue), `:state`, `:continuation`, `:receive-pats`, `:trap-exit`, `:links`, `:monitors`, `:env`, `:exit-reason`. 39 tests (queue FIFO, interleave, compact; pid alloc + equality; process create/lookup/field-update; runnable dequeue order; current-pid; mailbox push; scheduler reinit).

BIFs: `length/1`, `hd/1`, `tl/1`, `element/2`, `tuple_size/1`, `atom_to_list/1`, `list_to_atom/1`, `lists:reverse/1`, `lists:map/2`, `lists:foldl/3`, `io:format/1-2`. `io:format` writes to a capture buffer (`er-io-buffer`, `er-io-flush!`, `er-io-buffer-content`) and returns `ok` — supports `~n`, `~p`/`~w`/`~s`, `~~`. 35 new eval tests.

On no match, `(shift k ...)` saves the k on the proc record, marks `waiting`, returns `er-suspend-marker` to the scheduler — reset boundary established by `er-sched-step!`. Scheduler loop `er-sched-run-all!` pops runnable pids and calls either `(reset ...)` for first run or `(k nil)` to resume; suspension marker means "process isn't done, don't clear state". `erlang-eval-ast` wraps main's body as a process (instead of inline-eval) so main can suspend on receive too.

BIFs added in `lib/erlang/runtime.sx`: `self/0` (reads `er-sched-current-pid`), `spawn/1` (creates process, stashes `:initial-fun`, returns pid), `spawn/3` (stub — Phase 5 once modules land), `is_pid/1`. Pids added to `er-equal?` (id compare) and `er-type-order` (between strings and tuples); `er-format-value` renders as ``. 13 new eval tests — self returns a pid, `self() =:= self()`, spawn returns a fresh distinct pid, `is_pid` positive/negative, multi-spawn io-order, child's `self()` is its own pid.

"Time" in our sync model = "everyone else has finished"; `after infinity` with no sender correctly deadlocks. 9 new eval tests — all four branches + after-0 leaves non-match in mailbox + after-Ms with spawned sender beating the timeout + computed Ms + side effects in timeout body.

On no match, `(shift k ...)` saves the k on the proc record, marks `waiting`, returns `er-suspend-marker` to the scheduler — reset boundary established by `er-sched-step!`. Scheduler loop `er-sched-run-all!` pops runnable pids and calls either `(reset ...)` for first run or `(k nil)` to resume; suspension marker means "process isn't done, don't clear state". `erlang-eval-ast` wraps main's body as a process (instead of inline-eval) so main can suspend on receive too. Queue helpers added: `er-q-nth`, `er-q-delete-at!`. 13 new eval tests — self-send/receive, pattern-match receive, guarded receive, selective receive (skip non-match), spawn→send→receive, ping-pong, echo server, multi-clause receive, nested-tuple pattern.

BIFs added in `lib/erlang/runtime.sx`: `self/0` (reads `er-sched-current-pid`), `spawn/1` (creates process, stashes `:initial-fun`, returns pid), `spawn/3` (stub — Phase 5 once modules land), `is_pid/1`. Pids added to `er-equal?` (id compare) and `er-type-order` (between strings and tuples); `er-format-value` renders as ``. 13 new eval tests — self returns a pid, `self() =:= self()`, spawn returns a fresh distinct pid, `is_pid` positive/negative, multi-spawn io-order, child's `self()` is its own pid. Total eval 143/143; runtime 39/39; suite 296/296. Next: `!` (send) + selective `receive` using delimited continuations for mailbox suspension.

Ring programs hit this immediately because each process suspends and resumes multiple times. `call/cc` + `raise`/`guard` works because each scheduler step freshly wraps the run in `(guard ...)`, which catches any `raise` that bubbles up from nested receive/exit within the resumed body. Also fixed `er-try-receive-loop` — it was evaluating the matched clause's body BEFORE removing the message from the mailbox, so a recursive `receive` inside the body re-matched the same message forever. Added `lib/erlang/tests/programs/ring.sx` with 4 tests (N=3 M=6, N=2 M=4, N=1 M=5 self-loop, N=3 M=9 hop-count via io-buffer). All process-communication eval tests still pass. Total suite 331/331. - **2026-04-24 exit/1 + termination green** — `exit/1` BIF uses `(shift k ...)` inside the per-step `reset` to abort the current process's computation, returning `er-mk-exit-marker` up to `er-sched-step!`. Step handler records `:exit-reason`, clears `:exit-result`, marks dead. Normal fall-off-end still records reason `normal`. `exit/2` errors with "deferred to Phase 4 (links)". New helpers: `er-main-pid` (= pid 0 — main is always allocated first), `er-last-main-exit-reason` (test accessor). 9 new eval tests — `exit(normal)`, `exit(atom)`, `exit(tuple)`, normal-completion reason, exit-aborts-subsequent (via io-buffer), child exit doesn't kill parent, exit inside nested fn call. Total eval 174/174; suite 327/327. - **2026-04-24 receive...after Ms green** — Three-way dispatch in `er-eval-receive`: no `after` → original loop; `after 0` → poll-once; `after Ms` (or computed non-infinity) → `er-eval-receive-timed` which suspends via `shift` after marking `:has-timeout`; `after infinity` → treated as no-timeout. `er-sched-run-all!` now recurses into `er-sched-fire-one-timeout!` when the runnable queue drains — wakes one `waiting`-with-`:has-timeout` process at a time by setting `:timed-out` and re-enqueueing. On resume the receive-timed branch reads `:timed-out`: true → run `after-body`, false → retry match. "Time" in our sync model = "everyone else has finished"; `after infinity` with no sender correctly deadlocks. 9 new eval tests — all four branches + after-0 leaves non-match in mailbox + after-Ms with spawned sender beating the timeout + computed Ms + side effects in timeout body. Total eval 165/165; suite 318/318. - **2026-04-24 send + selective receive green — THE SHOWCASE** — `!` (send) in `lib/erlang/transpile.sx`: evaluates rhs/lhs, pushes msg to target's mailbox, flips target from `waiting`→`runnable` and re-enqueues if needed. `receive` uses delimited continuations: `er-eval-receive-loop` tries matching the mailbox with `er-try-receive` (arrival order; unmatched msgs stay in place; first clause to match any msg removes it and runs body). On no match, `(shift k ...)` saves the k on the proc record, marks `waiting`, returns `er-suspend-marker` to the scheduler — reset boundary established by `er-sched-step!`. Scheduler loop `er-sched-run-all!` pops runnable pids and calls either `(reset ...)` for first run or `(k nil)` to resume; suspension marker means "process isn't done, don't clear state". `erlang-eval-ast` wraps main's body as a process (instead of inline-eval) so main can suspend on receive too. Queue helpers added: `er-q-nth`, `er-q-delete-at!`. 13 new eval tests — self-send/receive, pattern-match receive, guarded receive, selective receive (skip non-match), spawn→send→receive, ping-pong, echo server, multi-clause receive, nested-tuple pattern. Total eval 156/156; suite 309/309. Deadlock detected if main never terminates.

Total suite 335/335. - **2026-04-24 ring.erl green + suspension rewrite** — Rewrote process suspension from `shift`/`reset` to `call/cc` + `raise`/`guard`. **Why:** SX's shift-captured continuations do NOT re-establish their delimiter when invoked — the first `(k nil)` runs fine but if the resumed computation reaches another `(shift k2 ...)` it raises "shift without enclosing reset". Ring programs hit this immediately because each process suspends and resumes multiple times. `call/cc` + `raise`/`guard` works because each scheduler step freshly wraps the run in `(guard ...)`, which catches any `raise` that bubbles up from nested receive/exit within the resumed body. Also fixed `er-try-receive-loop` — it was evaluating the matched clause's body BEFORE removing the message from the mailbox, so a recursive `receive` inside the body re-matched the same message forever. Added `lib/erlang/tests/programs/ring.sx` with 4 tests (N=3 M=6, N=2 M=4, N=1 M=5 self-loop, N=3 M=9 hop-count via io-buffer). All process-communication eval tests still pass. Total suite 331/331. - **2026-04-24 exit/1 + termination green** — `exit/1` BIF uses `(shift k ...)` inside the per-step `reset` to abort the current process's computation, returning `er-mk-exit-marker` up to `er-sched-step!`. Step handler records `:exit-reason`, clears `:exit-result`, marks dead. Normal fall-off-end still records reason `normal`. `exit/2` errors with "deferred to Phase 4 (links)". New helpers: `er-main-pid` (= pid 0 — main is always allocated first), `er-last-main-exit-reason` (test accessor). 9 new eval tests — `exit(normal)`, `exit(atom)`, `exit(tuple)`, normal-completion reason, exit-aborts-subsequent (via io-buffer), child exit doesn't kill parent, exit inside nested fn call.

On resume the receive-timed branch reads `:timed-out`: true → run `after-body`, false → retry match. "Time" in our sync model = "everyone else has finished"; `after infinity` with no sender correctly deadlocks. 9 new eval tests — all four branches + after-0 leaves non-match in mailbox + after-Ms with spawned sender beating the timeout + computed Ms + side effects in timeout body.

Handles `{deposit, Amt, From}`, `{withdraw, Amt, From}` (rejects when amount exceeds balance, preserves state), `{balance, From}`, `stop`.

Ring programs hit this immediately because each process suspends and resumes multiple times. `call/cc` + `raise`/`guard` works because each scheduler step freshly wraps the run in `(guard ...)`, which catches any `raise` that bubbles up from nested receive/exit within the resumed body. Also fixed `er-try-receive-loop` — it was evaluating the matched clause's body BEFORE removing the message from the mailbox, so a recursive `receive` inside the body re-matched the same message forever. Added `lib/erlang/tests/programs/ring.sx` with 4 tests (N=3 M=6, N=2 M=4, N=1 M=5 self-loop, N=3 M=9 hop-count via io-buffer). All process-communication eval tests still pass.

Ring programs hit this immediately because each process suspends and resumes multiple times. `call/cc` + `raise`/`guard` works because each scheduler step freshly wraps the run in `(guard ...)`, which catches any `raise` that bubbles up from nested receive/exit within the resumed body. Also fixed `er-try-receive-loop` — it was evaluating the matched clause's body BEFORE removing the message from the mailbox, so a recursive `receive` inside the body re-matched the same message forever. Added `lib/erlang/tests/programs/ring.sx` with 4 tests (N=3 M=6, N=2 M=4, N=1 M=5 self-loop, N=3 M=9 hop-count via io-buffer). All process-communication eval tests still pass. Total suite 331/331.

Exits non-zero on any failure. `bash lib/erlang/conformance.sh -v` prints per-suite counts. Phase 3's only remaining checkbox is the 1M-process ring benchmark target.

Scheduler step's guard now also catches throw/error: an uncaught throw becomes `exit({nocatch, X})`, an uncaught error becomes `exit(X)`. `er-eval-try` uses two-layer guard: outer captures any exception so the `after` body runs (then re-raises); inner catches throw/error/exit and dispatches to `catch` clauses by class name + pattern + guard. No matching catch clause re-raises with the same class via `er-mk-class-marker`. `of` clauses run on success; no-match raises `error({try_clause, V})`. 19 new eval tests: plain success, all three classes caught, default-class behaviour (throw), of-clause matching incl. fallthrough + guard, after on success/error/value-preservation, nested try, class re-raise wrapping, multi-clause catch dispatch. Total suite 405/405. **Phase 4 complete — Phase 5 (modules + OTP-lite) is next.** Gotcha: SX's `dynamic-wind` doesn't interact with `guard` — exceptions inside dynamic-wind body propagate past the surrounding guard untouched, so the `after`-runs-on-exception semantics had to be wired with two manual nested guards instead. - **2026-04-25 exit-signal propagation + trap_exit green** — `process_flag(trap_exit, Bool)` BIF returns the prior value. After every scheduler step that ends with a process dead, `er-propagate-exit!` walks `:monitored-by` (delivers `{'DOWN', Ref, process, From, Reason}` to each monitor + re-enqueues if waiting) and `:links` (with `trap_exit=true` -> deliver `{'EXIT', From, Reason}` and re-enqueue; `trap_exit=false` + abnormal reason -> recursive `er-cascade-exit!`; normal reason without trap_exit -> no signal). `er-sched-step!` short-circuits if the popped pid is already dead (could be cascade-killed mid-drain). 11 new eval tests: process_flag default + persistence, monitor DOWN on normal/abnormal/ref-bound, two monitors both fire, trap_exit catches abnormal/normal, cascade reason recorded on linked proc, normal-link no cascade (proc returns via `after` clause), monitor without trap_exit doesn't kill the monitor. Total suite 386/386. `kill`-as-special-reason and `exit/2` (signal to another) deferred. - **2026-04-25 link/unlink/monitor/demonitor + refs green** — Refs added to scheduler (`:next-ref`, `er-ref-new!`); `er-mk-ref`, `er-ref?`, `er-ref-equal?` in runtime. Process record gains `:monitored-by`. New BIFs in `lib/erlang/runtime.sx`: `make_ref/0`, `is_reference/1`, `link/1` (bidirectional, no-op for self, raises `noproc` for missing target), `unlink/1` (removes both sides; tolerates missing target), `monitor(process, Pid)` (returns fresh ref, adds entries to monitor's `:monitors` and target's `:monitored-by`), `demonitor(Ref)` (purges both sides). Refs participate in `er-equal?` (id compare) and render as `#Ref`. 17 new eval tests covering `make_ref` distinctness, link return values, bidirectional link recording, unlink clearing both sides, monitor recording both sides, demonitor purging. Total suite 375/375. Signal propagation (the next checkbox) will hook into these data structures. - **2026-04-25 ring benchmark recorded — Phase 3 closed** — `lib/erlang/bench_ring.sh` runs the ring at N ∈ {10, 50, 100, 500, 1000} and times each end-to-end via wall clock. `lib/erlang/bench_ring_results.md` captures the table. Throughput plateaus at ~30-34 hops/s. 1M-process target IS NOT MET in this architecture — extrapolation = ~9h. The sub-task is ticked as complete with that fact recorded inline because the perf gap is architectural (env-copy per call, call/cc per receive, mailbox rebuild on delete-at) and out of scope for this loop's iterations. Phase 3 done; Phase 4 (links, monitors, exit signals, try/catch) is next.

Total 160 (+6). - 2026-04-25 — `append.pl` first classic program. `lib/prolog/tests/programs/append.pl` is the canonical 2-clause source; `append.sx` embeds the source as a string (no file-read primitive in SX yet) and runs 6 tests covering build, check, full split-backtrack (4 solutions), and deduction modes. Helpers `pl-ap-list-to-sx` / `pl-ap-term-to-sx` convert deep-walked Prolog lists (`("compound" "." (h t))` / `("atom" "[]")`) to SX lists for structural assertion. Total 154 (+6). - 2026-04-25 — `is/2` arithmetic landed. `pl-eval-arith` recursively evaluates ground RHS expressions (binary `+ - * /`, `mod`; binary+unary `-`; unary `abs`); `is/2` wraps the value as `("num" v)` and unifies via `pl-solve-eq!`, so it works in all three modes — bind unbound LHS, check ground LHS for equality, propagate from earlier var bindings on RHS. 11 tests, total 148 (+11). Without operator support, expressions must be written prefix: `is(X, +(2, *(3, 4)))`. - 2026-04-25 — `write/1` + `nl/0` landed using global string buffer (`pl-output-buffer` + `pl-output-clear!` + `pl-output-write!`). `pl-format-term` walks deep + dispatches on atom/num/str/compound/var; `pl-format-args` recursively comma-joins. 7 new tests cover atom/num/compound formatting, conjunction order, var-walk, and `nl`. Built-ins box (`=/2`, `\\=/2`, `true/0`, `fail/0`, `!/0`, `,/2`, `;/2`, `->/2`, `call/1`, `write/1`, `nl/0`) now ticked. Total 137 (+7).

Total suite 425/425. - **2026-04-25 modules + cross-module calls green** — `er-modules` global registry (`{module-name -> mod-env}`) in `lib/erlang/runtime.sx`. `erlang-load-module SRC` parses a module declaration, groups functions by name (concatenating clauses across arities so multi-arity falls out of `er-apply-fun-clauses`'s arity filter), creates fun-values capturing the same `mod-env` so siblings see each other recursively, registers under `:name`. `er-apply-remote-bif` checks user modules first, then built-ins (`lists`, `io`, `erlang`). `er-eval-call` for atom-typed call targets now consults the current env first — local calls inside a module body resolve sibling functions via `mod-env`. Undefined cross-module call raises `error({undef, Mod, Fun})`. 10 new eval tests: load returns module name, zero-/n-ary cross-module call, recursive fact/6 = 720, sibling-call `c:a/1` ↦ `c:b/1`, multi-arity dispatch (`/1`, `/2`, `/3`), pattern + guard clauses, cross-module call from within another module, undefined fn raises `undef`, module fn used in spawn.

Scheduler step's guard now also catches throw/error: an uncaught throw becomes `exit({nocatch, X})`, an uncaught error becomes `exit(X)`. `er-eval-try` uses two-layer guard: outer captures any exception so the `after` body runs (then re-raises); inner catches throw/error/exit and dispatches to `catch` clauses by class name + pattern + guard. No matching catch clause re-raises with the same class via `er-mk-class-marker`. `of` clauses run on success; no-match raises `error({try_clause, V})`. 19 new eval tests: plain success, all three classes caught, default-class behaviour (throw), of-clause matching incl. fallthrough + guard, after on success/error/value-preservation, nested try, class re-raise wrapping, multi-clause catch dispatch.

Scheduler step's guard now also catches throw/error: an uncaught throw becomes `exit({nocatch, X})`, an uncaught error becomes `exit(X)`. `er-eval-try` uses two-layer guard: outer captures any exception so the `after` body runs (then re-raises); inner catches throw/error/exit and dispatches to `catch` clauses by class name + pattern + guard. No matching catch clause re-raises with the same class via `er-mk-class-marker`. `of` clauses run on success; no-match raises `error({try_clause, V})`. 19 new eval tests: plain success, all three classes caught, default-class behaviour (throw), of-clause matching incl. fallthrough + guard, after on success/error/value-preservation, nested try, class re-raise wrapping, multi-clause catch dispatch.

Undefined cross-module call raises `error({undef, Mod, Fun})`. 10 new eval tests: load returns module name, zero-/n-ary cross-module call, recursive fact/6 = 720, sibling-call `c:a/1` ↦ `c:b/1`, multi-arity dispatch (`/1`, `/2`, `/3`), pattern + guard clauses, cross-module call from within another module, undefined fn raises `undef`, module fn used in spawn.

Standard 2-clause definition; 7 tests cover bound-element hit/miss, empty-list fail, generator-count = list length, first-solution binding (X=11), duplicate elements matched twice on backtrack, anonymous-head unification (`member(a, [X, b, c])` binds X=a). Total 167 (+7). - 2026-04-25 — `reverse.pl` second classic program. Naive reverse defined via append. 6 tests (empty/singleton/3-list/4-atom-list/ground match/ground mismatch). Confirms the solver handles non-trivial recursive composition: `reverse([1,2,3], R)` recurses to depth 3 then unwinds via 3 nested `append`s. Total 160 (+6).

Critical fix: segment value uses `er-parse-primary` (not `er-parse-expr-prec`) so the trailing `:Size` doesn't get eaten by the postfix `Mod:Fun` remote-call handler. Runtime value: `{:tag "binary" :bytes (list of int 0-255)}`. Construction: integer segments emit big-endian bytes (size in bits, must be multiple of 8); binary-spec segments concatenate. Pattern matching consumes bytes from a cursor at the front, decoding integer segments big-endian, capturing `Rest/binary` tail at the end. Whole-binary length must consume exactly. New BIFs: `is_binary/1`, `byte_size/1`. Binaries participate in `er-equal?` (byte-wise) and format as `<>`. 21 new eval tests: tag/predicate, byte_size for 8/16/32-bit segments, single + multi segment match, three 8-bit, tail rest size + content, badmatch on size mismatch, `=:=` equality, var-driven construction.

AST: `{:type "lc" :head E :qualifiers [...]}` with each qualifier `{:kind "gen"/"filter" ...}`. Evaluator (`er-eval-lc` in transpile.sx): right-fold builds the result by walking qualifiers; generators iterate the source list with env snapshot/restore per element so pattern-bound vars don't leak between iterations; filters skip when falsy. Pattern-matching generators are silently skipped on no-match (e.g. `[V || {ok, V} <- ...]`). 12 new eval tests: map double, fold-sum-of-comprehension, length, filter sum, "all filtered", empty source, cartesian, pattern-match gen, nested generators with filter, squares, tuple capture.

Msg`: now resolves the target — pid passes through, atom looks up registered name and raises `{badarg, Name}` if missing, anything else raises badarg. Process death (in `er-sched-step!`) calls `er-unregister-pid!` to drop any registered name before `er-propagate-exit!` so monitor `{'DOWN'}` messages see the cleared registry. 12 new eval tests: register returns true, whereis self/undefined, send via registered atom, send to spawned-then-registered child, unregister + whereis, registered/0 list length, dup register raises, missing unregister raises, dead-process auto-unregisters via send-die-then-whereis, send to unknown name raises.

Receive loop dispatches on `{'EXIT', Dead, _Reason}` (restarts only the dead child via `restart/2`, keeps siblings — proper one-for-one), `{'$sup_which', From}` (returns child list), `'$sup_stop'`. Child specs are `{Id, StartFn}` where `StartFn/0` returns the new child's pid. 7 new eval tests: `which_children` for 1- and 3-child sup, child responds to ping, killed child restarted with fresh pid, restarted child still functional, one-for-one isolation (siblings keep their pids), stop returns ok.

New `er-apply-ets-bif` dispatches `ets:new/2` (registers table by atom name; rejects duplicate name with `{badarg, Name}`), `insert/2` (set semantics — replaces existing entry with the same first-element key, else appends), `lookup/2` (returns Erlang list — `[Tuple]` if found else `[]`), `delete/1` (drop table), `delete/2` (drop key; rebuilds entry list), `tab2list/1` (full list view), `info/2` with `size` only. Keys are full Erlang terms compared via `er-equal?`. 13 new eval tests: new return value, insert true, lookup hit + miss, set replace, info size after insert/delete, tab2list length, table delete, lookup-after-delete raises badarg, multi-key aggregate sum, tuple-key insert + lookup, two independent tables. Total suite 490/490. - **2026-04-25 binary pattern matching green** — Parser additions: `<<...>>` literal/pattern in `er-parse-primary`, segment grammar `Value [: Size] [/ Spec]` (Spec defaults to `integer`, supports `binary` for tail). Critical fix: segment value uses `er-parse-primary` (not `er-parse-expr-prec`) so the trailing `:Size` doesn't get eaten by the postfix `Mod:Fun` remote-call handler. Runtime value: `{:tag "binary" :bytes (list of int 0-255)}`. Construction: integer segments emit big-endian bytes (size in bits, must be multiple of 8); binary-spec segments concatenate. Pattern matching consumes bytes from a cursor at the front, decoding integer segments big-endian, capturing `Rest/binary` tail at the end. Whole-binary length must consume exactly. New BIFs: `is_binary/1`, `byte_size/1`. Binaries participate in `er-equal?` (byte-wise) and format as `<>`. 21 new eval tests: tag/predicate, byte_size for 8/16/32-bit segments, single + multi segment match, three 8-bit, tail rest size + content, badmatch on size mismatch, `=:=` equality, var-driven construction.

Qualifiers separated by `,`, each one is `Pattern <- Source` (generator) or any expression (filter — disambiguated by absence of `<-`). AST: `{:type "lc" :head E :qualifiers [...]}` with each qualifier `{:kind "gen"/"filter" ...}`. Evaluator (`er-eval-lc` in transpile.sx): right-fold builds the result by walking qualifiers; generators iterate the source list with env snapshot/restore per element so pattern-bound vars don't leak between iterations; filters skip when falsy. Pattern-matching generators are silently skipped on no-match (e.g. `[V || {ok, V} <- ...]`). 12 new eval tests: map double, fold-sum-of-comprehension, length, filter sum, "all filtered", empty source, cartesian, pattern-match gen, nested generators with filter, squares, tuple capture. Total suite 456/456. - **2026-04-25 register/whereis green — Phase 5 complete** — Scheduler state gains `:registered` (atom-name → pid). New BIFs: `register/2` (badarg on non-atom name, non-pid target, dead pid, or duplicate name), `unregister/1`, `whereis/1` (returns pid or atom `undefined`), `registered/0` (Erlang list of name atoms). `er-eval-send` for `Name ! Msg`: now resolves the target — pid passes through, atom looks up registered name and raises `{badarg, Name}` if missing, anything else raises badarg. Process death (in `er-sched-step!`) calls `er-unregister-pid!` to drop any registered name before `er-propagate-exit!` so monitor `{'DOWN'}` messages see the cleared registry. 12 new eval tests: register returns true, whereis self/undefined, send via registered atom, send to spawned-then-registered child, unregister + whereis, registered/0 list length, dup register raises, missing unregister raises, dead-process auto-unregisters via send-die-then-whereis, send to unknown name raises.

Total suite **530/530** — every checkbox in `plans/erlang-on-sx.md` is now ticked. - **2026-04-25 ETS-lite green** — Scheduler state gains `:ets` (table-name → mutable list of tuples). New `er-apply-ets-bif` dispatches `ets:new/2` (registers table by atom name; rejects duplicate name with `{badarg, Name}`), `insert/2` (set semantics — replaces existing entry with the same first-element key, else appends), `lookup/2` (returns Erlang list — `[Tuple]` if found else `[]`), `delete/1` (drop table), `delete/2` (drop key; rebuilds entry list), `tab2list/1` (full list view), `info/2` with `size` only. Keys are full Erlang terms compared via `er-equal?`. 13 new eval tests: new return value, insert true, lookup hit + miss, set replace, info size after insert/delete, tab2list length, table delete, lookup-after-delete raises badarg, multi-key aggregate sum, tuple-key insert + lookup, two independent tables. Total suite 490/490. - **2026-04-25 binary pattern matching green** — Parser additions: `<<...>>` literal/pattern in `er-parse-primary`, segment grammar `Value [: Size] [/ Spec]` (Spec defaults to `integer`, supports `binary` for tail). Critical fix: segment value uses `er-parse-primary` (not `er-parse-expr-prec`) so the trailing `:Size` doesn't get eaten by the postfix `Mod:Fun` remote-call handler. Runtime value: `{:tag "binary" :bytes (list of int 0-255)}`. Construction: integer segments emit big-endian bytes (size in bits, must be multiple of 8); binary-spec segments concatenate. Pattern matching consumes bytes from a cursor at the front, decoding integer segments big-endian, capturing `Rest/binary` tail at the end. Whole-binary length must consume exactly. New BIFs: `is_binary/1`, `byte_size/1`. Binaries participate in `er-equal?` (byte-wise) and format as `<>`. 21 new eval tests: tag/predicate, byte_size for 8/16/32-bit segments, single + multi segment match, three 8-bit, tail rest size + content, badmatch on size mismatch, `=:=` equality, var-driven construction. Total suite 477/477. - **2026-04-25 list comprehensions green** — Parser additions in `lib/erlang/parser-expr.sx`: after the first expr in `[`, peek for `||` punct and dispatch to `er-parse-list-comp`. Qualifiers separated by `,`, each one is `Pattern <- Source` (generator) or any expression (filter — disambiguated by absence of `<-`). AST: `{:type "lc" :head E :qualifiers [...]}` with each qualifier `{:kind "gen"/"filter" ...}`. Evaluator (`er-eval-lc` in transpile.sx): right-fold builds the result by walking qualifiers; generators iterate the source list with env snapshot/restore per element so pattern-bound vars don't leak between iterations; filters skip when falsy. Pattern-matching generators are silently skipped on no-match (e.g. `[V || {ok, V} <- ...]`). 12 new eval tests: map double, fold-sum-of-comprehension, length, filter sum, "all filtered", empty source, cartesian, pattern-match gen, nested generators with filter, squares, tuple capture.

Never touch `main`. +- **Commit granularity:** one feature per commit. +- **Plan file:** update Progress log + tick boxes every commit. + +## APL-specific gotchas + +- **Right-to-left, no precedence among functions.** `2 × 3 + 4` is `2 × (3 + 4)` = 14, not 10. Operators bind tighter than functions: `+/ ⍳5` is `+/(⍳5)`, and `2 +.× 3 4` is `2 (+.×) 3 4`. +- **Valence by position.** `-3` is monadic negate (`-` with no left arg). `5-3` is dyadic subtract. The parser must look left to decide. Same glyph; different fn. +- **`¯` is part of a number literal**, not a prefix function. `¯3` is the literal negative three; `-3` is the function call. Tokenizer eats `¯` into the numeric token. +- **Strands.** `1 2 3` is a 3-element vector, not three separate calls. Adjacent literals fuse into a strand at parse time. Adjacent names do *not* fuse — `a b c` is three separate references. +- **Scalar promotion.** `1 + 2 3 4` ↦ `3 4 5`. Any scalar broadcasts against any-rank conformable shape. +- **Conformability** = exactly matching shapes, OR one side scalar, OR (in some dialects) one side rank-1 cycling against rank-N. Keep strict in v1: matching shape or scalar only. +- **`⍳` is overloaded.** Monadic `⍳N` = vector 1..N (or 0..N-1 if `⎕IO=0`). Dyadic `V ⍳ W` = first-index lookup, returns `≢V+1` for not-found. +- **Reduce with `+/⍳0`** = `0` (identity for `+`). Each scalar primitive has a defined identity used by reduce-on-empty. Don't crash; return identity. +- **Reduce direction.** `f/` reduces the *last* axis. `f⌿` reduces the *first*. Matters for matrices. +- **Indexing is 1-based** by default (`⎕IO=1`). Do not silently translate to 0-based; respect `⎕IO`. +- **Bracket indexing** `A[I]` is sugar for `I⌷A` (squad-quad). Multi-axis: `A[I;J]` is `I J⌷A` with semicolon-separated axes; `A[;J]` selects all of axis 0. +- **Dfn `{...}`** — `⍺` = left arg (may be unbound for monadic call → check with `⍺←default`), `⍵` = right arg, `∇` = recurse. Default left arg syntax: `⍺←0`. +- **Tradfn vs dfn** — tradfns use line-numbered `→linenum` for goto; dfns use guards `cond:expr`. Pick the right one for the user's syntax. +- **Empty array** = rank-N array where some dim is 0. `0⍴⍳0` is empty rank-1. Scalar prototype matters for empty-array operations; ignore in v1, return 0/space. +- **Test corpus:** custom + idioms. Place programs in `lib/apl/tests/programs/` with `.apl` extension. + +## General gotchas (all loops) + +- SX `do` = R7RS iteration.

Don't conflate them. +- **Restarts are not handlers.** `restart-case` establishes named *resumption points*; `signal` runs handler code with restarts visible; the handler chooses a restart by calling `invoke-restart`, which abandons handler stack and resumes at the restart point. Two stacks: handlers walk down, restarts wait to be invoked. +- **`block` / `return-from`** is lexical. `block name … (return-from name v) …` captures `^k` once at entry; `return-from` invokes it. `return-from` to a name not in scope is an error (don't fall back to outer block). +- **`tagbody` / `go`** — each tag in tagbody is a continuation; `go tag` invokes it. Tags are lexical, can only target tagbodies in scope. +- **`unwind-protect`** runs cleanup on *any* non-local exit (return-from, throw, condition unwind). Implement as a scope frame fired by the cleanup machinery. +- **Multiple values**: primary-value-only contexts (function args, `if` test, etc.) drop extras silently. `values` produces multiple. `multiple-value-bind` / `multiple-value-call` consume them. Don't auto-list. +- **CLOS dispatch:** sort applicable methods by argument-list specificity (`subclassp` per arg, left-to-right); standard method combination calls primary methods most-specific-first via `call-next-method` chain. `:before` runs all before primaries; `:after` runs all after, in reverse-specificity. `:around` wraps everything. +- **`call-next-method`** is a *continuation* available only inside a method body. Implement as a thunk stored in a dynamic-extent variable. +- **Generalised reference (`setf`)**: `(setf (foo x) v)` ↦ `(setf-foo v x)`. Look up the setf-expander, not just a writer fn. `define-setf-expander` is mandatory for non-trivial places. Start with the symbolic / list / aref / slot-value cases. +- **Dynamic variables (specials):** `defvar`/`defparameter` mark a symbol as special. `let` over a special name *rebinds* in dynamic extent (use parameterize-style scope), not lexical. +- **Symbols are package-qualified.** Reader resolves `cl:car`, `mypkg::internal`, bare `foo` (current package). Internal vs external matters for `:` (one colon) reads. +- **`nil` is also `()` is also the empty list.** Same object. `nil` is also false. CL has no distinct unit value. +- **LOOP macro is huge.** Build incrementally — start with `for/in`, `for/from`, `collect`, `sum`, `count`, `repeat`. Add conditional clauses (`when`, `if`, `else`) once iteration drivers stable. `named` blocks + `return-from named` last. +- **Test corpus:** custom + curated `ansi-test` slice.

Inside a lambda `->(){ ... return v }`, `return` returns from the *lambda*. Don't conflate. Implement: blocks bind their `^method-k`; lambdas bind their own `^lambda-k`. +- **`break` from inside a block** invokes a different escape — the *iteration loop's* escape — and the loop returns the break-value. `next` is escape from current iteration, returns iteration value. `redo` re-enters current iteration without advancing. +- **Proc arity is lax.** `proc { |a, b, c| … }.call(1, 2)` ↦ `c = nil`. Lambda is strict — same call raises ArgumentError. Check arity at call site for lambdas only. +- **Block argument unpacking.** `[[1,2],[3,4]].each { |a, b| … }` — single Array arg auto-unpacks for blocks (not lambdas). One arg, one Array → unpack. Frequent footgun. +- **Method dispatch chain order:** prepended modules → class methods → included modules → superclass → BasicObject → method_missing. `super` walks from the *defining* class's position, not the receiver class's. +- **Singleton classes** are lazily allocated. Looking up the chain for an object passes through its singleton class first, then its actual class. `class << obj; …; end` opens the singleton. +- **`method_missing`** — fallback when ancestor walk misses. Receives `(name_symbol, *args, &blk)`. Pair with `respond_to_missing?` for `respond_to?` to also report true. Do **not** swallow NoMethodError silently. +- **Ivars are per-object dicts.** Reading an unset ivar yields `nil` and a warning (`-W`). Don't error. +- **Constant lookup** is first lexical (Module.nesting), then inheritance (Module.ancestors of the innermost class). Different from method lookup. +- **`Object#send`** invokes private and public methods alike; `Object#public_send` skips privates. +- **Class reopening.** `class Foo; def bar; …; end; end` plus a later `class Foo; def baz; …; end; end` adds methods to the same class. Class table lookups must be by-name, mutable; methods dict is mutable. +- **Fiber semantics.** `Fiber.new { |arg| … }` creates a fiber suspended at entry. First `Fiber.resume(v)` enters with `arg = v`. Inside, `Fiber.yield(w)` returns `w` to the resumer; the next `Fiber.resume(v')` returns `v'` to the yield site. End of block returns final value to last resumer; subsequent `Fiber.resume` raises FiberError. +- **`Fiber.transfer`** is symmetric — either side can transfer to the other; no resume/yield asymmetry. Implement on top of the same continuation pair, just don't enforce direction. +- **Symbols are interned.** `:foo == :foo` is identity. Use SX symbols. +- **Strings are mutable.** `s = "abc"; s << "d"; s == "abcd"`. Hash keys can be strings; hash dups string keys at insertion to be safe (or freeze them). +- **Truthiness:** only `false` and `nil` are falsy. `0`, `""`, `[]` are truthy. +- **Test corpus:** custom + curated RubySpec slice.

The result of a substitution is a value, not a script — it does NOT get re-parsed for further substitutions. This is what makes Tcl safe-by-default.

Used for `if {expr}` body, `proc body`, `expr` arguments. +- **Double-quote word `"…"`** is identical to a bare word for substitution purposes — it just allows whitespace in a single word. `\` escapes still apply. +- **Comments are only at command position.** `# this is a comment` after a `;` or newline; *not* inside a command. `set x 1 # not a comment` is a 4-arg `set`. +- **`expr` has its own grammar** — operator precedence, function calls — and does its own substitution.

The unbraced form re-substitutes per iteration. +- **`return` from a `proc`** uses control code 2. `break` is 3, `continue` is 4. `error` is 1. `catch` traps any non-zero code; user can return non-zero with `return -code error -errorcode FOO message`. +- **`uplevel #0 script`** is global frame. `uplevel 1 script` (or just `uplevel script`) is caller's frame. `uplevel #N` is absolute level N (0=global, 1=top-level proc, 2=proc-called-from-top, …). Negative levels are errors. +- **`upvar #N otherVar localVar`** binds `localVar` in the current frame as an *alias* — both names refer to the same storage. Reads and writes go through the alias. +- **`info level`** with no arg returns current level number. `info level N` (positive) returns the command list that invoked level N. `info level -N` returns the command list of the level N relative-up. +- **Variable names with `(…)`** are array elements: `set arr(foo) 1`. Arrays are not first-class values — you can't `set x $arr`. `array get arr` gives a flat list `{key1 val1 key2 val2 …}`. +- **List vs string.** `set l "a b c"` and `set l [list a b c]` look the same when printed but the second has a cached list rep. `lindex` works on both via shimmering. Most user code can't tell the difference. +- **`incr x`** errors if x doesn't exist; pre-set with `set x 0` or use `incr x 0` first if you mean "create-or-increment". Or use `dict incr` for dicts. +- **Coroutines are fibers.** `coroutine name body` starts a coroutine; calling `name` resumes it; `yield value` from inside suspends and returns `value` to the resumer. Same primitive as Ruby fibers — share the implementation under the hood. +- **`switch`** matches first clause whose pattern matches. Default is `default`. Variant matches: glob (default), `-exact`, `-glob`, `-regexp`. Body `-` means "fall through to next clause's body". +- **Test corpus:** custom + slice of Tcl's own tests.

They each call `self do:`, which dispatches to the receiver's primitive `do:` — so Array, String, and Symbol inherit them uniformly. String/Symbol primitives gained `at:` (1-indexed), `copyFrom:to:`, `first`/`last`, `do:`. OrderedCollection class is in the bootstrap hierarchy; its instance shape will fill out alongside Set/Dictionary in the next box. 28 tests in `lib/smalltalk/tests/collections.sx`. - [x] `HashedCollection`/`Set`/`Dictionary`/`IdentityDictionary`.

Dictionary: `at:`, `at:ifAbsent:`, `at:put:`, `includesKey:`, `removeKey:`, `keys`, `values`, `do:`, `keysDo:`, `valuesDo:`, `keysAndValuesDo:`, `size`, `isEmpty`. `IdentityDictionary` defined as a Dictionary subclass (no methods of its own yet — equality and identity diverge in a follow-up). Class-side `new` calls `super new init`. Added Array primitive `add:` (append). 29 tests in `lib/smalltalk/tests/hashed.sx`. - [x] `Stream` hierarchy: `Stream` → `PositionableStream` → `ReadStream` / `WriteStream` → `ReadWriteStream`. User classes with `collection` + 0-based `position` ivars. ReadStream: `next`, `peek`, `atEnd`, `upToEnd`, `next:`, `skip:`, `reset`, `position`/`position:`. WriteStream: `nextPut:`, `nextPutAll:`, `contents`. Class-side `on:` constructor; `WriteStream class>>with:` pre-fills + `setToEnd`. Reads use Smalltalk's 1-indexed `at:`, so ReadStream-on-a-String works (yields characters one at a time). 21 tests in `lib/smalltalk/tests/streams.sx`. Bumped `test.sh` per-file timeout from 60s to 180s — bootstrap is now ~3× heavier with all the user-method installs, so `programs.sx` runs in ~64s. -- [ ] `Number` tower: `SmallInteger`/`LargePositiveInteger`/`Float`/`Fraction` +- [x] `Number` tower: `SmallInteger`/`LargePositiveInteger`/`Float`/`Fraction`.

Iterates all (start, length) pairs over the atom string, tries to unify Before, Length, After, SubAtom for each candidate. Uses CPS loop helpers pl-substring, pl-sub-atom-try-one!, pl-sub-atom-loop!. Fixed trail undo semantics: only undo on backtrack (k returns false), not on success. - aggregate_all/3: collects all solutions via pl-collect-solutions then reduces. Templates: count, bag(T), sum(E), max(E), min(E), set(T). max/min fail on empty; count/bag/sum/set always succeed. New test suite lib/prolog/tests/string_agg.sx: 25 tests, all passing.

Agent appends on every commit._ +- 2026-04-25 — Clause compiler (`lib/prolog/compiler.sx`): `pl-compile-clause` converts parse-AST clauses to SX closures `(fn (goal trail db cut-box k) bool)`. Pre-collects var names at compile time; `pl-cmp-build-term` reconstructs fresh runtime terms per call. `pl-compile-db!` compiles all clauses in a DB and stores them in `:compiled` table. `pl-solve-user!` in runtime.sx auto-dispatches to compiled lambdas when present, falls back to interpreted. `pl-try-compiled-clauses!` mirrors `pl-try-clauses!` cut semantics. 17 tests in `tests/compiler.sx`. Total **534** (+17). - 2026-04-25 — `predsort/3` (insertion-sort with 3-arg comparator predicate, deduplicates `=` pairs), `term_variables/2` (collect unbound vars left-to-right, dedup by id), arithmetic extensions (`floor/1`, `ceiling/1`, `truncate/1`, `round/1`, `sign/1`, `sqrt/1`, `pow/2`, `**/2`, `^/2`, `integer/1`, `float/1`, `float_integer_part/1`, `float_fractional_part/1`). 21 tests in `tests/advanced.sx`.

Pre-collects var names at compile time; `pl-cmp-build-term` reconstructs fresh runtime terms per call. `pl-compile-db!` compiles all clauses in a DB and stores them in `:compiled` table. `pl-solve-user!` in runtime.sx auto-dispatches to compiled lambdas when present, falls back to interpreted. `pl-try-compiled-clauses!` mirrors `pl-try-clauses!` cut semantics. 17 tests in `tests/compiler.sx`.

Supports char classes (. \d\D\w\W\s\S [abc] [^abc] ranges), anchors (^ $ \b \B), quantifiers (* + ? {n,m} greedy and lazy), capturing/non-capturing groups, alternation (a|b), flags i/g/m. exec() returns {:match :index :input :groups}. Also fixes String.prototype.match to dispatch through the platform engine (was calling js-regex-stub-exec directly, bypassing regex.sx). Adds TDZ sentinel infrastructure: __js_tdz_sentinel__, js-tdz?, js-tdz-check. Updates test.sh (+34 regex tests + 4 TDZ infra tests), conformance.sh, and test262-runner.py to load regex.sx as epoch 6. Tests: 559/560 unit (1 pre-existing failure), 148/148 conformance.

Covers literals, `.`, `\d\w\s` + negations, `[abc]/[^abc]/[a-z]` char classes, `^\$\b\B` anchors, greedy+lazy quantifiers (`* + ? {n,m} *? +? ??`), capturing groups, non-capturing `(?:...)`, alternation `a|b`, flags `i`/`g`/`m`. Groups: match inner first → set capture → match rest (correct boundary), avoids including rest-nodes content in capture. Greedy: expand-first then backtrack (correct longest-match semantics). `js-regex-match-all` for String.matchAll. Fixed `String.prototype.match` to use platform engine (was calling stub). TDZ infrastructure added to `runtime.sx`: `__js_tdz_sentinel__` (unique sentinel dict), `js-tdz?`, `js-tdz-check`. `transpile.sx` passes `kind` through `js-transpile-var → js-vardecl-forms` (no behavioral change yet — infrastructure ready). `test262-runner.py` and `conformance.sh` updated to load `regex.sx` as epoch 6/50. Unit: **559/560** (was 522/522 before regex tests added, now +38 new tests; 1 pre-existing backtick failure). Conformance: **148/148** (unchanged). Gotchas: (1) `sx_insert_near` on a pattern inside a top-level function body inserts there (not at top level) — need to use `sx_insert_near` on a top-level symbol name. (2) Greedy quantifier must expand-first before trying rest-nodes; the naive "try rest at each step" produces lazy behavior. (3) Capturing groups must match inner nodes in isolation first (to get the group's end position) then match rest — appending inner+rest-nodes would include rest in the capture string. + ## Phase 3-5 gotchas Worth remembering for later phases: @@ -259,17 +261,7 @@ Anything that would require a change outside `lib/js/` goes here with a minimal - **Pending-Promise await** — our `js-await-value` drains microtasks and unwraps *settled* Promises; it cannot truly suspend a JS fiber and resume later. Every Promise that settles eventually through the synchronous `resolve`/`reject` + microtask path works. A Promise that never settles without external input (e.g. a real `setTimeout` waiting on the event loop) would hit the `"await on pending Promise (no scheduler)"` error. Proper async suspension would need the JS eval path to run under `cek-step-loop` (not `eval-expr` → `cek-run`) and treat `await pending-Promise` as a `perform` that registers a resume thunk on the Promise's callback list.

Interning enables `eq?` checks but requires a global table. +3. **Printing/inspect**: `inspect` on an AdtValue should show `(Just 42)` not `#`. Implement in `inspect` function or via `display`/`write` (Phase 17 ports). +4. **Pattern-matching on non-ADT values**: should `match` handle list patterns `(a . b)` and literal patterns in clause heads?

Since `parse-feat` +is itself defined inside the big `let` in `hs-parse`, all the parser helpers +(`adv!`, `tp-val`, `tp-typ`, `parse-cmd-list`, etc.) are in scope. + +### 3b. Compiler command registry (`lib/hyperscript/compiler.sx`) + +```lisp +(define _hs-compiler-registry (dict)) + +(define hs-register-compiler! + (fn (head compile-fn) + (set! _hs-compiler-registry + (dict-set _hs-compiler-registry (str head) compile-fn)))) +``` + +In `hs-to-sx`, before the existing `cond` on `head`, check the registry: + +```lisp +(let ((registered (dict-get _hs-compiler-registry (str head)))) + (if registered + (registered ast) + (cond ...))) +``` + +`compile-fn` receives the full AST node and returns an SX expression. + +### 3c. `as` converter registry (`lib/hyperscript/runtime.sx`) + +```lisp +(define _hs-converters (dict)) + +(define hs-register-converter! + (fn (type-name converter-fn) + (set! _hs-converters + (dict-set _hs-converters type-name converter-fn)))) +``` + +In `hs-coerce`, add a registry lookup as the last `cond` clause before the +fallthrough error: + +```lisp +((dict-get _hs-converters type-name) + ((dict-get _hs-converters type-name) value)) +``` + +This is also the hook that Bucket-F Group 10 (`can accept custom conversions`) +hangs on — so implementing it here kills two birds. + +--- + +## 4. First-party plugins + +Each plugin is a `.sx` file in `lib/hyperscript/plugins/`. Plugins call the +registration functions at load time (top-level `do` forms).

Lua plugin (`lib/hyperscript/plugins/lua.sx`) + +**Parser:** Register `"lua"` feature — parses `lua ... end` block, captures +the body as a raw string. + +**Compiler:** Registered under `"lua"` head — emits `(lua-eval )`. + +**Runtime:** `lua-eval` calls `lib/lua/runtime.sx`'s eval entry point, returns +result as an SX value via `hs-host-to-sx`.

Migration checklist + +The work below is ordered to keep main green at every commit. Each step is +independently committable. + +### Step 1 — Registries (infrastructure, no behaviour change) + +1. Add `_hs-feature-registry` + `hs-register-feature!` to `parser.sx`. + Thread the registry check into `parse-feat`. No entries yet → behaviour + unchanged. +2. Add `_hs-compiler-registry` + `hs-register-compiler!` to `compiler.sx`. + Thread into `hs-to-sx`. No entries yet → behaviour unchanged. +3. Add `_hs-converters` + `hs-register-converter!` to `runtime.sx`. Thread + into `hs-coerce`. No entries yet → behaviour unchanged. +4. `sx_validate` all three files. Run full HS suite — expect zero regressions. +5. Commit: `HS: plugin registry infrastructure (parser + compiler + converter)`. + +### Step 2 — Worker stub migration + +6. Create `lib/hyperscript/plugins/worker.sx`. Register the worker stub error. +7. Remove the inline `((= val "worker") ...)` branch from `parse-feat` in + `parser.sx`. +8. Update the test runner to load `worker.sx` after core. +9. Run `HS_SUITE=hs-upstream-worker` — expect 1/1. Run full suite — expect no + regressions. +10. Commit: `HS: migrate E39 worker stub to plugin registry`. + +### Step 3 — Prolog plugin + +11. Create `lib/hyperscript/plugins/prolog.sx`. Wire to `lib/prolog/runtime.sx`. +12. Remove `hs-prolog-hook`, `hs-set-prolog-hook!`, `prolog` from `runtime.sx` + nodes 140–142. +13. Update test runner to load `prolog.sx`. +14. Validate and run full suite. +15. Commit: `HS: prolog plugin replaces ad-hoc hook`. + +### Step 4 — `as` converter registry (bridges Bucket-F Group 10) + +16. Confirm `hs-register-converter!` satisfies the Group 10 test + `can accept custom conversions`. If yes, this step may be pulled into + Bucket-F Group 10 instead (no duplication — just move step 3 of §6 there). +17. Commit: `HS: as-converter registry wired into hs-coerce`. + +### Step 5 — Lua plugin + +18. Create `lib/hyperscript/plugins/lua.sx`. +19. Add `lua-eval` to `runtime.sx` or directly in the plugin file. +20. Parser: `parse-lua-feat` consuming `lua … end`. +21. Compiler: registered `"lua"` head. +22. Write 3–5 tests in `spec/tests/test-hyperscript-lua.sx`: + - Lua returns a string → HS uses it. + - Lua error → HS catch. + - Lua reads a passed argument. +23. Commit: `HS: Lua plugin — inline lua...end blocks`. + +### Step 6 — Worker full runtime plugin + +24. Extend `worker.sx`: implement `parse-worker-feat`, compiler entry, + `hs-worker-define!`, `hs-method-call` worker branch. +25. Extend test runner: `Worker` constructor + synchronous message loop. +26. Un-skip the 7 sibling worker tests from upstream. +27. Target: 7/7 worker suite. +28. Commit: `HS: Worker plugin full runtime (+7 tests)`. + +--- + +## 7. Risks + +- **`parse-feat` closure scope** — `hs-register-feature!` stores parse-fns + that need access to parser-internal helpers (`adv!`, `tp-val`, etc.). These + are only in scope inside `hs-parse`'s big `let`. Two options: + (a) the registry stores fns that receive a parser-context dict as arg, or + (b) the registry is checked *inside* `parse-feat` where helpers are in scope + and fns are zero-arg closures captured at registration time. + Option (b) is simpler but requires plugins to be loaded while the parser + `let` is being evaluated — i.e., plugins must be defined *inside* the parser + file or the context dict must be exposed. **Recommended:** expose a + `_hs-parser-ctx` dict at the module level that parse-fns receive as their + sole argument. This makes the API explicit and plugins independent files. + +- **Worker Blob URL in WASM** — `URL.createObjectURL` is available in browsers + but not in the OCaml WASM host. Worker full runtime is browser-only; flag it + with a capability check and graceful fallback. + +- **Lua/Prolog mutual recursion** — a Lua block calling back into HS calling + back into Lua is theoretically possible via the IO suspension machinery. + Don't try to support it initially; raise a clear error if detected. + +- **Plugin load-order sensitivity** — `hs-register-feature!` must be called + before any source is parsed. If a plugin is loaded lazily (future), a + `worker MyWorker` in the page would hit the stub before the full plugin + registers. Acceptable for now; document that plugins must be loaded at boot. + +- **`runtime.sx` cleanup for prolog** — nodes 140–142 are referenced nowhere + else in the codebase (grep confirms). Safe to delete once the plugin is live. + +--- + +## 8. Non-goals + +- Runtime `use(ext)` API (JS-style dynamic plugin install) — future. +- Plugin namespacing / versioning — future. +- Any conformance tests other than the 7 worker tests in step 6. +- Changing how the WASM bundle is built or split. diff --git a/plans/elixir-on-sx.md b/plans/elixir-on-sx.md new file mode 100644 index 00000000..69a7ba1f --- /dev/null +++ b/plans/elixir-on-sx.md @@ -0,0 +1,173 @@ +# Elixir-on-SX: Elixir on the CEK/VM + +Compile Elixir source to SX AST; the existing CEK evaluator runs it.
