Phase 3 done; Phase 4 (links, monitors, exit signals, try/catch) is next. - **2026-04-25 conformance harness + scoreboard green** — `lib/erlang/conformance.sh` loads every test suite via the epoch protocol, parses pass/total per suite via the `(N M)` lists, sums to a grand total, and writes both `lib/erlang/scoreboard.json` (machine-readable) and `lib/erlang/scoreboard.md` (Markdown table with ✅/❌ markers). 9 suites × full pass = 358/358. 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. - **2026-04-25 fib_server.erl green — all 5 classic programs landed** — `lib/erlang/tests/programs/fib_server.sx` with 8 tests. Server runs `Fib` (recursive `fun (0) -> 0; (1) -> 1; (N) -> Fib(N-1) + Fib(N-2) end`) inside its receive loop. Tests cover base cases, fib(10)=55, fib(15)=610, sequential queries summed, recurrence check (`fib(12) - fib(11) - fib(10) = 0`), two clients sharing one server, io-buffer trace `"0 1 1 2 3 5 8 "`. Total suite 358/358. Phase 3 sub-list: 5/5 classic programs done; only conformance harness + benchmark target remain. - **2026-04-25 echo.erl green** — `lib/erlang/tests/programs/echo.sx` with 7 tests. Server: `receive {From, Msg} -> From ! Msg, Loop(); stop -> ok end`. Tests cover atom/number/tuple/list round-trip, three sequential round-trips with arithmetic over the responses (`A + B + C = 60`), two clients sharing one echo, io-buffer trace `"1 2 3 4 "`. Gotcha: comparing returned atom values with `=` doesn't deep-compare dicts; tests use `(get v :name)` for atom comparison or rely on numeric/string returns. Total suite 350/350.

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. - **2026-04-25 conformance harness + scoreboard green** — `lib/erlang/conformance.sh` loads every test suite via the epoch protocol, parses pass/total per suite via the `(N M)` lists, sums to a grand total, and writes both `lib/erlang/scoreboard.json` (machine-readable) and `lib/erlang/scoreboard.md` (Markdown table with ✅/❌ markers). 9 suites × full pass = 358/358. 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. - **2026-04-25 fib_server.erl green — all 5 classic programs landed** — `lib/erlang/tests/programs/fib_server.sx` with 8 tests. Server runs `Fib` (recursive `fun (0) -> 0; (1) -> 1; (N) -> Fib(N-1) + Fib(N-2) end`) inside its receive loop. Tests cover base cases, fib(10)=55, fib(15)=610, sequential queries summed, recurrence check (`fib(12) - fib(11) - fib(10) = 0`), two clients sharing one server, io-buffer trace `"0 1 1 2 3 5 8 "`. Total suite 358/358. Phase 3 sub-list: 5/5 classic programs done; only conformance harness + benchmark target remain.

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. Total suite 415/415. - **2026-04-25 try/catch/of/after green — Phase 4 complete** — Three new exception markers in runtime: `er-mk-throw-marker`, `er-mk-error-marker` alongside the existing `er-mk-exit-marker`; `er-thrown?`, `er-errored?` predicates. `throw/1` and `error/1` BIFs raise their respective markers. 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.

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.

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.

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.

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.

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.

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.

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.

Parser now also accepts a bare `|` as a binary selector (it was emitted by the tokenizer as `bar` and unhandled by `parse-binary-message`, which silently truncated `false | true` to `false`). - [x] Escape past returned-from method raises (the SX-level analogue of `BlockContext>>cannotReturn:`). Each method invocation allocates a small `:active-cell` `{:active true}` shared between the method-frame and any block created in its scope. `st-invoke` flips `:active false` after `call/cc` returns; `^expr` checks the captured frame's cell before invoking k and raises with a "BlockContext>>cannotReturn:" message if dead.

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.

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.

From c70bbdeb362d090febd3353a1adb5ad2551be13e Mon Sep 17 00:00:00 2001 From: giles Date: Sun, 26 Apr 2026 12:10:50 +0000 Subject: [PATCH 071/154] =?UTF-8?q?ocaml:=20numeric=20tower=20=E2=80=94=20?= =?UTF-8?q?Integer/Number=20distinction=20+=20float=20contagion?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Add `Integer of int` to sx_types.ml alongside `Number of float`. Parser produces Integer for whole-number literals. Arithmetic primitives apply float contagion (int op int → Integer, int op float → Number). Division always returns Number. Rounding (floor/truncate/round) returns Integer. Predicates: integer?, float?, exact?, inexact?, exact->inexact, inexact->exact. run_tests.ml updated for json_of_value, value_of_json, identical?, random-int mock, DOM accessors, and parser pattern matches. New spec/tests/test-numeric-tower.sx — 92 tests, all pass (394 unchanged).

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?
