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.

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`.

Still untyped. -- **Phase 3** — **laziness**: thunk-wrap every application arg, `force` = WHNF, pattern match forces scrutinee. Classic programs (infinite Fibonacci, sieve of Eratosthenes, quicksort, n-queens, expression calculator) green. -- **Phase 4** — Hindley-Milner type inference (Algorithm W, let-polymorphism, type-sig checking) -- **Phase 5** — typeclasses (dictionary passing, Eq/Ord/Show/Num/Functor/Monad/Applicative, `deriving`) -- **Phase 6** — real `IO` monad backed by `perform`/`resume`, full Prelude, drive corpus to 150+ +- **Phase 7** — String = [Char] via O(1) string-view dicts.

Native SX strings +also satisfy `hk-str?` (offset = 0 implicitly). No OCaml changes needed. + +- `hk-str?` covers both native strings and view dicts. +- `hk-str-head v` returns the character at offset `n` as an **integer** (ord + value). Char = integer throughout. +- `hk-str-tail v` returns a new view dict with offset `n+1`; **O(1)**. +- `hk-str-null? v` is true when offset ≥ string length. +- In `match.sx`, the `":"` cons-pattern branch checks `hk-str?` on the scrutinee + **before** the normal tagged-list path. On a string: head = char-int, tail = + shifted view (or `(list "[]")` if exhausted). +- `chr n` converts an integer back to a single-character SX string for display + and for `++`. +- `++` between two strings concatenates natively via `str`; no cons-spine built. +- The natural hazard: any code that checks `(list? v)` or `(= (first v) ":")` on + a value must be audited — string views are dicts, not lists.

After new programs, run `bash lib/haskell/conformance.sh`. ## Haskell-specific gotchas -- **Layout rule is the hard bit of parsing** — you need a lexer-parser feedback loop that inserts virtual `{`, `;`, `}` based on indentation. Budget proportionally. -- **Every application arg is a thunk** — compiling `f x y` to `(f (thunk x) (thunk y))` not `(f x y)`. Pattern-match forces. -- **ADT representation:** tagged list, e.g. `data Maybe a = Nothing | Just a` → constructors are `(:Nothing)` (0-ary) and `(:Just )` (1-ary). Pattern match on the head symbol. -- **Let-polymorphism** (phase 4): generalise at let-binding boundaries only, not at lambda. -- **Typeclass dictionaries** (phase 5): each class is a record type; each instance builds the record; method call = project + apply. -- **`IO`** (phase 6): internally `World -> (a, World)` but in practice backed by `perform`/`resume` for real side effects. Desugar `do`-notation to `>>=`. -- **Out of scope:** GHC extensions. No `DataKinds`, `GADTs`, `TypeFamilies`, `TemplateHaskell`. Stick to Haskell 98. +- **String views are dicts** — `(list? v)` returns false for a string view. + Audit every value-dispatch chain in `match.sx` and `eval.sx` for this. +- **Char = integer** — `'a'` parses to int 97. `chr 97 = "a"` (1-char string). + Do not represent Char as a 1-char SX string internally. +- **`deriving Show`** (Phase 8): nested constructor args need parens if their + show string contains a space. Rule: `if string-contains (show arg) " " then + "(" ++ show arg ++ ")" else show arg`. +- **`error` tag** (Phase 9): use `(raise (list "hk-error" msg))`. The top-level + `hk-run-io` guard must catch this tag; do not let `hk-error` leak as an + uncaught SX exception into the test runner's output. +- **`Data.Map` module resolution** (Phase 11): qualified imports `import + qualified Data.Map as Map` need the eval import handler to resolve the dotted + module name to the `map.sx` namespace dict. Check `hk-bind-decls!` import arm. +- **Record update field index** (Phase 14): `r { field = v }` needs the field → + positional-index mapping at runtime. Store it in `hk-constructors` when + registering `:con-rec`. +- **IORef mutation** (Phase 15): `dict-set!` is the SX in-place mutator. The + `IORef` dict is heap-allocated and passed by reference — mutation is safe. +- **Every application arg is a thunk** — `f x y` → `(f (thunk x) (thunk y))`. + Pattern-match forces before matching. Builtins force their args. +- **ADT representation:** `("Just" thunk)`, `("Nothing")`, `(":" h t)`, `("[]")`. +- **Let-polymorphism:** generalise at let-binding boundaries only, not lambda. +- **Typeclass dictionaries:** class = record; instance = record value; method + call = project + apply. Defaults stored under `"__default__ClassName_method"`, + used as fallback when the instance dict lacks the key. +- **Out of scope:** GHC extensions. No `DataKinds`, `GADTs`, `TypeFamilies`, + `TemplateHaskell`. Haskell 98 only. ## General gotchas (all loops) -- SX `do` = R7RS iteration.

Full suite 4280/1080 (was 4243/1117, +37). Committed 5d1913e7. +- 2026-04-26: Phase 6 Spec match done — ADT case added to match-pattern in spec/evaluator.sx: checks (list? pattern)+(symbol? first)+(dict? value)+(get value :_adt), then matches :_ctor+arity and recursively binds field patterns. No-clause error now uses make-cek-value+raise-eval-frame so guard can catch it. 20 new match tests pass; 40/40 total ADT tests green.

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.

Result is the cascade's last send (or first, depending on parser variant — pick one and document). +- **`super` send** looks up starting from the *defining* class's superclass, not the receiver class.

Mutating one rep dirties the cached string and vice versa. +- **The Dodekalogue is strict.** Substitution is **one-pass**, **left-to-right**. 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. Don't accidentally re-parse. +- **Brace word `{…}`** is the only way to defer evaluation. No substitution inside, just balanced braces. 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. Brace `expr {$x + 1}` to avoid double-substitution and to enable bytecode caching. +- **`if` and `while` re-parse** the condition only if not braced. Always use `if {…}`/`while {…}` form. 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.

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). The host loads +plugins explicitly after the core files. + +### 4a. Worker plugin (`lib/hyperscript/plugins/worker.sx`) + +**Phase 1 — stub migration (immediate):** +Remove the inline error branch from `parse-feat` (the E39 stub). Replace with: + +```lisp +(hs-register-feature! "worker" + (fn () + (error "worker plugin is not installed — see https://hyperscript.org/features/worker"))) +``` + +This is identical behaviour to E39 but routed through the registry. The stub +lives in the plugin file, not the core parser. No test regression. + +**Phase 2 — full runtime:** + +Parser: `parse-worker-feat` — consumes `worker [(*)] * end`, +returns `(worker Name urls defs)` AST node. + +Compiler: registered under `"worker"` head: +- Emits `(hs-worker-define! "Name" urls defs)` call. + +Runtime additions in the plugin file: +- `hs-worker-define!` — creates a `{:_hs-worker true :name N :handle H :exports (...)}` record, + binds it in the HS top-level env under `Name`. +- `hs-method-call` (existing) detects `:_hs-worker` and dispatches via `postMessage`. +- Worker script body compiled to a standalone SX bundle posted to a Blob URL. +- Return values are promise-wrapped; async-transparent via `perform`/IO suspension. + +Mock env additions for the test runner: `Worker` constructor + synchronous +message loop for the 7 sibling `test.skip(...)` upstream tests (the ones +deferred in E39). + +### 4b. Prolog plugin (`lib/hyperscript/plugins/prolog.sx`) + +Replaces the ad-hoc `hs-prolog-hook` in `runtime.sx`. + +**Parser:** Register `"prolog"` feature — parses +`prolog(, )` at feature level (alternative: keep as an +expression, register a compiler extension only). + +**Compiler:** Registered under `"prolog"` head — emits `(prolog db goal)`. + +**Runtime:** The existing `prolog` function in `runtime.sx` moves here. +`hs-prolog-hook` and `hs-set-prolog-hook!` are removed from `runtime.sx` and +the hook mechanism is replaced by the plugin loading `lib/prolog/runtime.sx` +and wiring the solver directly. + +Remove from `runtime.sx` nodes 140–142 once the plugin is live. + +### 4c. 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`. Errors surface as HS `catch`-able +exceptions. + +This enables inline Lua in HyperScript: + +``` +on click + lua + return document.title:upper() + end + put it into me +end +``` + +--- + +## 5. Load order + +``` +lib/hyperscript/parser.sx ;; defines _hs-feature-registry, hs-register-feature! +lib/hyperscript/compiler.sx ;; defines _hs-compiler-registry, hs-register-compiler! +lib/hyperscript/runtime.sx ;; defines _hs-converters, hs-register-converter! +lib/hyperscript/plugins/worker.sx +lib/hyperscript/plugins/prolog.sx +lib/hyperscript/plugins/lua.sx +``` + +The test runner (`tests/hs-run-filtered.js`) loads plugins after core. The +browser WASM bundle includes all three by default (plugins are small; no +reason to lazy-load them). + +--- + +## 6. 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/designs/sx-adt.md b/plans/designs/sx-adt.md new file mode 100644 index 00000000..8526e767 --- /dev/null +++ b/plans/designs/sx-adt.md @@ -0,0 +1,257 @@ +# SX Algebraic Data Types — Design + +## Motivation + +Every language implementation currently uses `{:tag "..." :field ...}` tagged dicts to +simulate sum types.

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. 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 444/444. **Phase 5 complete — Phase 6 (list comprehensions, binary patterns, ETS) is the last phase.** +- **2026-04-25 supervisor (one-for-one) green** — `er-supervisor-source` in `lib/erlang/runtime.sx` is the canonical Erlang text of a minimal supervisor; `er-load-supervisor!` registers it. Implements `start_link(Mod, Args)` (sup process traps exits, calls `Mod:init/1` to get child-spec list, runs `start_child/1` for each which links the spawned pid back to itself), `which_children/1`, `stop/1`. 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. Total suite 432/432. +- **2026-04-25 gen_server (OTP-lite) green** — `er-gen-server-source` in `lib/erlang/runtime.sx` is the canonical Erlang text of the behaviour; `er-load-gen-server!` registers it in the user-module table. Implements `start_link/2`, `call/2` (sync via `make_ref` + selective `receive {Ref, Reply}`), `cast/2` (async fire-and-forget returning `ok`), `stop/1`, and the receive loop dispatching `{'$gen_call', {From, Ref}, Req}` → `Mod:handle_call/3`, `{'$gen_cast', Msg}` → `Mod:handle_cast/2`, anything else → `Mod:handle_info/2`. handle_call reply tuples supported: `{reply, R, S}`, `{noreply, S}`, `{stop, R, Reply, S}`. handle_cast/info: `{noreply, S}`, `{stop, R, S}`. `Mod:F` and `M:F` where `M` is a runtime variable now work via new `er-resolve-call-name` (was bug: passed unevaluated AST node `:value` to remote dispatch). 10 new eval tests: counter callback module (start/call/cast/stop, repeated state mutations), LIFO stack callback module (`{push, V}` cast, pop returns `{ok, V}` or `empty`, size). 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. 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. +- **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. +- **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. +- **2026-04-24 bank.erl green** — `lib/erlang/tests/programs/bank.sx` with 8 tests. Stateful server pattern: `Server = fun (Balance) -> receive ... Server(NewBalance) end end` recursively threads balance through each iteration. Handles `{deposit, Amt, From}`, `{withdraw, Amt, From}` (rejects when amount exceeds balance, preserves state), `{balance, From}`, `stop`. Tests cover deposit accumulation, withdrawal within balance, insufficient funds with state preservation, mixed transactions, clean shutdown, two-client interleave. Total suite 343/343. +- **2026-04-24 ping_pong.erl green** — `lib/erlang/tests/programs/ping_pong.sx` with 4 tests: classic Pong server + Ping client with separate `ping_done`/`pong_done` notifications, 5-round trace via io-buffer (`"ppppp"`), main-as-pinger-4-rounds (no intermediate Ping proc), tagged-id round-trip (`"4 3 2 1 "`). All driven by `Ping = fun (Target, K) -> ... Ping(Target, K-1) ... end` self-recursion — captured-env reference works because `Ping` binds in main's mutable env before any spawned body looks it up. 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. 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. +- **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. Next: `!` (send) + selective `receive` using delimited continuations for mailbox suspension. +- **2026-04-24 scheduler foundation green** — `lib/erlang/runtime.sx` + `lib/erlang/tests/runtime.sx`. Amortised-O(1) FIFO queue (`er-q-new`, `er-q-push!`, `er-q-pop!`, `er-q-peek`, `er-q-compact!` at 128-entry head drift), tagged pids `{:tag "pid" :id N}` with `er-pid?`/`er-pid-equal?`, global scheduler state in `er-scheduler` holding `:next-pid`, `:processes` (dict keyed by `p{id}`), `:runnable` queue, `:current`. 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). Total erlang suite 283/283. Next: `spawn/1`, `!`, `receive` wired into the evaluator. +- **2026-04-24 core BIFs + funs green** — Phase 2 complete. Added to `lib/erlang/transpile.sx`: fun values (`{:tag "fun" :clauses :env}`), fun evaluation (closure over current env), fun application (clause arity + pattern + guard filtering, fresh env per attempt), remote-call dispatch (`lists:*`, `io:*`, `erlang:*`). 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. 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. +- **2026-04-24 pattern matching green** — `er-match!` in `lib/erlang/transpile.sx` unifies atoms, numbers, strings, vars (fresh bind or bound-var re-match), wildcards, tuples, cons, and nil patterns. `case ... of ... [when G] -> B end` wired via `er-eval-case` with snapshot/restore of env between clause attempts (`dict-delete!`-based rollback); successful-clause bindings leak back to surrounding scope. 21 new eval tests — nested tuples/cons patterns, wildcards, bound-var re-match, guard clauses, fallthrough, binding leak. Total eval 75/75; erlang suite 189/189. +- **2026-04-24 eval (sequential) green** — `lib/erlang/transpile.sx` (tree-walking interpreter) + `lib/erlang/tests/eval.sx`. 54/54 tests covering literals, arithmetic, comparison, logical (incl. short-circuit `andalso`/`orelse`), tuples, lists with `++`, `begin..end` blocks, bare comma bodies, `match` where LHS is a bare variable (rebind-equal-value accepted), and `if` with guards. 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. - **parser green** — `lib/erlang/parser.sx` + `parser-core.sx` + `parser-expr.sx` + `parser-module.sx`. 52/52 in `tests/parse.sx`. Covers literals, tuples, lists (incl. `[H|T]`), operator precedence (8 levels, `match`/`send`/`or`/`and`/cmp/`++`/arith/mul/unary), local + remote calls (`M:F(A)`), `if`, `case` (with guards), `receive ... after ... end`, `begin..end` blocks, anonymous `fun`, `try..of..catch..after..end` with `Class:Pattern` catch clauses. Module-level: `-module(M).`, `-export([...]).`, multi-clause functions with guards. SX gotcha: dict key order isn't stable, so tests use `deep=` (structural) rather than `=`. - **tokenizer green** — `lib/erlang/tokenizer.sx` + `lib/erlang/tests/tokenize.sx`. Covers atoms (bare, quoted, `node@host`), variables, integers (incl. `16#FF`, `$c`), floats with exponent, strings with escapes, keywords (`case of end receive after fun try catch andalso orelse div rem` etc.), punct (`( ) { } [ ] , ; . : :: -> <- <= => << >> | ||`), ops (`+ - * / = == /= =:= =/= < > =< >= ++ -- ! ?`), `%` line comments. 62/62 green. diff --git a/plans/go-on-sx.md b/plans/go-on-sx.md new file mode 100644 index 00000000..d6a93848 --- /dev/null +++ b/plans/go-on-sx.md @@ -0,0 +1,145 @@ +# Go-on-SX: Go on the CEK/VM + +Compile Go source to SX AST; the existing CEK evaluator runs it.

The design uses **string views** implemented as +pure-SX dicts, requiring no OCaml changes. + +### Representation + +A string view is a dict `{:hk-str buf :hk-off n}` where `buf` is a native SX +string and `n` is the current offset (zero-based code-unit index). Native SX +strings also satisfy the predicate (offset = 0 implicitly). + +- `hk-str?` returns true for both native strings and string-view dicts. +- `hk-str-head v` extracts the character at offset `n` as an integer (ord value). +- `hk-str-tail v` returns a new view with offset `n+1`; O(1). +- `hk-str-null? v` is true when offset equals the string's length. + +### Char = integer + +`Char` is represented as a plain integer (its Unicode code point / ord value). +`chr n` converts back to a single-character string for display and `++`. `ord c` +is the identity (the integer itself). `toUpper`/`toLower` operate on the integer, +looking up ASCII ranges. This is already consistent with the existing `ord 'A' = +65` tests. + +### Pattern matching + +In `match.sx`, the cons-pattern branch (`":"` constructor) checks `hk-str?` on +the scrutinee **before** the normal tagged-list path. When the scrutinee is a +string view (or native string), decompose as: +- head → `hk-str-head` (an integer char-code) +- tail → `hk-str-tail` (a new string view, or `(list "[]")` if exhausted) + +The nil-pattern `"[]"` matches when `hk-str-null?` is true. + +### Complexity + +- `head s` / `tail s` — O(1) via view shift +- `s !! n` — O(n) (n tail calls) +- `(c:s)` construction — O(n) for full `[Char]` construction (same as real Haskell) +- `++` on two strings — native `str` concat, O(length left) +- `length` — O(n); `words`/`lines` — O(n) + +No OCaml changes are needed. The view type is fully representable as an SX dict. + +## Ground rules + +- **Scope:** only `lib/haskell/**` and `plans/haskell-completeness.md`.

Built-ins were strict + in all args by default (every collected thunk forced before + invoking the underlying SX fn) — that defeats `seq`'s purpose, + which is strict in its first argument and lazy in its second. + Added a tiny `lazy` flag on the builtin record (set by a new + `hk-mk-lazy-builtin` constructor) and routed `hk-apply-builtin` + to skip the auto-force when the flag is true. `seq a b` calls + `hk-force a` then returns `b` unchanged so its laziness is + preserved; `deepseq` does the same with `hk-deep-force`. 9 new + tests in `lib/haskell/tests/seq.sx` cover primitive, computed, + and let-bound first args, deepseq on a list / `Just` / + tuple, seq inside arithmetic, seq via a fun-clause, and + `[seq 1 10, seq 2 20]` to confirm seq composes inside list + literals.

Two + evaluator changes turn the lazy primitives into a working + language: + 1. Op-form `:` is now non-strict in both args — `hk-eval-op` + special-cases it before the eager force-and-binop path, so a + cons-cell holds two thunks.

Operators are now first-class values via a small + `hk-make-binop-builtin` helper, so `(+)`, `(*)`, `(==)` etc. + can be passed to `zipWith` and `map`. + Added range support across parser + evaluator: `[from..to]` and + `[from,next..to]` evaluate eagerly via `hk-build-range` (handles + step direction); `[from..]` parses to a new `:range-from` node + that the evaluator desugars to `iterate (+ 1) from`.

Added a thunk type to + `lib/haskell/eval.sx` (`hk-mk-thunk` / `hk-is-thunk?`) backed by a + one-shot memoizing `hk-force` that evaluates the deferred AST, then + flips a `forced` flag and caches the value on the thunk dict; the + shared `hk-deep-force` walks the result tree at the test/output + boundary. Three single-line wiring changes in the evaluator make + every application argument lazy: `:app` now wraps its argument in + `hk-mk-thunk` rather than evaluating it. To preserve correctness + where values must be inspected, `hk-apply`, `hk-eval-op`, + `hk-eval-if`, `hk-eval-case`, and `hk-eval` for `:neg` now force + their operand. `hk-apply-builtin` forces every collected arg + before invoking the underlying SX fn so built-ins (`error`, `not`, + `id`) stay strict. The pattern matcher in `match.sx` now forces + the scrutinee just-in-time only for patterns that need to inspect + shape — `p-wild`, `p-var`, `p-as`, and `p-lazy` are no-force + paths, so the value flows through as a thunk and binding + preserves laziness. `hk-match-list-pat` forces at every cons-spine + step. 6 new lazy-specific tests in `lib/haskell/tests/eval.sx` + verify that `(\x y -> x) 1 (error …)` and `(\x y -> y) (error …) 99` + return without diverging, that `case Just (error …) of Just _ -> 7` + short-circuits, that `const` drops its second arg, that + `myHead (1 : error … : [])` returns 1 without touching the tail, + and that `Just (error …)` survives a wildcard-arm `case`. 333/333 + green, all prior eval tests preserved by deep-forcing the result + in `hk-eval-expr-source` and `hk-prog-val`. + +- **2026-04-24** — Phase 2 evaluator (`lib/haskell/eval.sx`) — ties + the whole pipeline together. Strict semantics throughout (laziness + is Phase 3). Function values are tagged dicts: `closure`, + `multi`(fun), `con-partial`, `builtin`. `hk-apply` unifies dispatch + across all four; closures and multifuns curry one argument at a + time, multifuns trying each clause's pat-list in order once arity + is reached. Top-level `hk-bind-decls!` is three-pass — + collect groups + pre-seed names → install multifuns (so closures + observe later names) → eval 0-arity bodies and pat-binds — making + forward and mutually recursive references work. `hk-eval-let` does + the same trick with a mutable child env. Built-ins: + `error`/`not`/`id`, plus `otherwise = True`. Operators wired: + arithmetic, comparison (returning Bool conses), `&&`, `||`, `:`, + `++`. Sections evaluate the captured operand once and return a + closure synthesized via the existing AST. `hk-eval-program` + registers data decls then binds, returning the env; `hk-run` + fetches `main` if present. Also extended `runtime.sx` to + pre-register the standard Prelude conses (`Maybe`, `Either`, + `Ordering`) so expression-level eval doesn't need a leading + `data` decl. 48 new tests in `lib/haskell/tests/eval.sx` cover + literals, arithmetic precedence, comparison/Bool, `if`, `let` + (incl. recursive factorial), lambdas (incl. constructor pattern + args), constructors, `case` (Just/Nothing/literal/tuple/wildcard), + list literals + cons + `++`, tuples, sections, multi-clause + top-level (factorial, list length via cons pattern, Maybe handler + with default), user-defined `data` with case-style matching, a + binary-tree height program, currying, higher-order (`twice`), + short-circuit `error` via `if`, and the three built-ins. 329/329 + green.

Eight existing + tests updated to the pattern-flavoured AST. Also fixed a pragmatic + layout issue that surfaced in multi-line `let`s: when a layout-indent + would emit a spurious `;` just before an `in` token (because the + let block had already been closed by dedent), `hk-peek-next-reserved` + now lets the layout pass skip that indent and leave closing to the + existing `in` handler. 18 new tests in + `lib/haskell/tests/parser-patterns.sx` cover every pattern variant, + lambda with mixed apats, let pattern-bindings (tuple / constructor / + cons), and do-bind with a tuple pattern. 138/138 green. + +- **2026-04-24** — Phase 1: `case … of` and `do`-notation parsers.
