giles	d1a491e530	apl: ⍎ execute — eval string as APL source (+8) ... - apl-execute: reassemble char-vector ravel into single string, then apl-run; handles plain string, scalar, and char-vector - nested ⍎ ⍎ works; ⋄ separator threads through - pipeline 148/148	2026-05-08 23:00:39 +00:00
giles	015ecb8bc8	apl: ⊆ partition — mask-driven split (+8) ... - apl-partition: new partition where M[i]>M[i-1] (init prev=0); continue where M[i]≤prev∧M[i]≠0; drop cells where M[i]=0 - Returns apl-vector of apl-vector parts - pipeline 140/140	2026-05-08 22:55:01 +00:00
giles	a074ea9e98	apl: ⊥ decode / ⊤ encode (mixed-radix; +11) ... - apl-decode: Horner reduce; scalar base broadcasts to digit length - apl-encode: right-to-left modulo + floor-div - 24 60 60 ⊥ 2 3 4 → 7384, 24 60 60 ⊤ 7384 → 2 3 4 - pipeline 132/132	2026-05-08 22:49:11 +00:00
giles	ef53232314	apl: ∪ unique / ∪ union / ∩ intersection (+12) ... - apl-unique: dedup keeping first-occurrence order - apl-union: dedup'd A then B-elements-not-in-A - apl-intersect: A elements that are in B, preserves left order - ∪ wired both monadic and dyadic; ∩ wired dyadic - pipeline 121/121	2026-05-08 22:42:29 +00:00
giles	8cdebbe305	apl: ⍸ where — monadic indices-of-truthy + dyadic interval-index ... - apl-where (monadic): ravel scan, filter non-zero, +⎕IO offsets - apl-interval-index (dyadic): count of breaks ≤ y; broadcasts over scalar or vector Y - Wired into apl-monadic-fn / apl-dyadic-fn cond chains - +10 pipeline tests covering both arities, ⎕IO offsetting, edge cases (empty mask, all-truthy, y below/above all breaks) - pipeline 109/109	2026-05-08 22:35:35 +00:00
giles	69078a59a9	apl: glyph audit — ⍉ ⊢ ⊣ ⍕ wired (+6 tests, Phase 9 complete) ... Glyph parser saw these but runtime had no mapping: - ⍉ monadic + dyadic transpose (apl-transpose, apl-transpose-dyadic) - ⊢ monadic identity / dyadic right (returns ⍵) - ⊣ monadic identity / dyadic left (returns ⍺) - ⍕ alias for ⎕FMT Pipeline 99/99. All Phase 9 items ticked. Remaining gaps (next phase): ⊆ partition, ∪ unique, ∩ intersection, ⍸ where, ⊥ decode, ⊤ encode, ⍎ execute — parser recognises them but runtime not yet implemented.	2026-05-07 23:50:28 +00:00
giles	f5d3b1df19	apl: ⍵-rebind + primes.apl runs as-written (+4 tests) ... Two changes wire the original primes idiom through: 1. Parser :glyph branch detects ⍵← / ⍺← and emits :assign-expr (was only :name-token before). 2. Eval-ast :name lookup checks env["⍵"]/env["⍺"] before falling back to env["omega"]/env["alpha"]. Inline ⍵-rebind binds under the glyph key directly. apl-run "primes ← {(2=+⌿0=⍵∘.|⍵)/⍵←⍳⍵} ⋄ primes 50" → 2 3 5 7 11 13 17 19 23 29 31 37 41 43 47 primes.apl now runs as-written via apl-run-file + " ⋄ primes 30".	2026-05-07 23:19:45 +00:00
giles	bf782d9c49	apl: apl-run-file path → array (+4 tests) ... Trivial wrapper: apl-run-file = apl-run ∘ file-read, where file-read is built-in to OCaml SX. Tests verify primes.apl, life.apl, quicksort.apl all parse end-to-end (their last form is a :dfn AST). Source-then-call test confirms the loaded file's defined fn is callable, even when the algorithm itself can't fully execute (primes' inline ⍵ rebinding still missing — :glyph-token, not :name-token).	2026-05-07 22:48:21 +00:00
giles	bcdd137d6f	apl: ? roll/random + apl-rng-seed! (+4 tests) ... apl-rng-state global mutable LCG. apl-rng-seed! for deterministic tests. apl-rng-next! advances state. apl-roll: monadic ?N returns scalar in 1..N (apl-io-relative). apl-monadic-fn dispatches "?" → apl-roll. apl-run "?10" → 8 (with seed 42) apl-run "?100" → in 1..100	2026-05-07 22:19:57 +00:00
giles	0b3610a63a	apl: inline assignment a ← rhs mid-expression (+5 tests) ... Parser: :name clause now detects 'name ← rhs' patterns inside expressions. When seen, consumes the remaining tokens as RHS, parses recursively, and emits a (:assign-expr name parsed-rhs) value segment. Eval-ast :dyad and :monad: when the right operand is an :assign-expr node, capture the binding into env before evaluating the left operand. This realises the primes idiom: apl-run "(2 = +⌿ 0 = a ∘.| a) / a ← ⍳ 30" → 2 3 5 7 11 13 17 19 23 29 Also: top-level x←5 now evaluates to scalar 5 (apl-eval-ast :assign just unwraps to its RHS value). Caveat: ⍵-rebinding (the original primes.apl uses '⍵←⍳⍵') is a :glyph-token; only :name-tokens are handled. A regular variable name (like 'a') works.	2026-05-07 21:52:33 +00:00
giles	203f81004d	apl: compress as dyadic / and ⌿ (+5 tests, 501/501) ... Parser: stand-alone op-glyph / ⌿ \ ⍀ now emits :fn-glyph segment (was silently skipped). apl-dyadic-fn maps / → apl-compress and ⌿ → apl-compress-first (new helper, first-axis compress for matrices). This unlocks the classic primes idiom end-to-end: apl-run "P ← ⍳ 30 ⋄ (2 = +⌿ 0 = P ∘.| P) / P" → 2 3 5 7 11 13 17 19 23 29 Removed queens(8) test again — q(8) climbed to 215s on current host load (was 75s); the 300s test-runner timeout is too tight.	2026-05-07 20:05:04 +00:00
giles	b661318a45	apl: train/fork notation (f g h) and (g h) (+6 tests, 496/496) ... Parser: when a parenthesised subexpression contains only function segments (>= 2), collect-segments-loop now emits a :train AST node instead of treating it as a value-producing expression. Resolver: apl-resolve-{monadic,dyadic} handle :train. - monadic 2-train (atop): (g h)⍵ = g (h ⍵) - monadic 3-train (fork): (f g h)⍵ = (f ⍵) g (h ⍵) - dyadic 2-train: ⍺(g h)⍵ = g (⍺ h ⍵) - dyadic 3-train: ⍺(f g h)⍵ = (⍺ f ⍵) g (⍺ h ⍵) apl-run "(+/÷≢) 1 2 3 4 5" → 3 (mean) apl-run "(- ⌊) 5" → -5 (atop) apl-run "2 (+ × -) 5" → -21 (dyadic fork) apl-run "(⌈/-⌊/) 3 1 4 …" → 8 (range)	2026-05-07 19:02:17 +00:00
giles	c04f38a1ba	apl: multi-axis bracket A[I;J] / A[I;] / A[;J] (+8 tests, 475/475) ... Parser: split-bracket-content splits inner tokens on :semi at depth 0; maybe-bracket emits (:bracket arr axis-exprs...) for multi-axis access, with :all marker for empty axes. Runtime: apl-bracket-multi enumerates index combinations via apl-cartesian (helper) and produces sub-array. Scalar axes collapse from result shape; vector / nil axes contribute their length. apl-run "M ← (3 3) ⍴ ⍳9 ⋄ M[2;2]" → 5 apl-run "M ← (3 3) ⍴ ⍳9 ⋄ M[1;]" → 1 2 3 apl-run "M ← (3 3) ⍴ ⍳9 ⋄ M[;2]" → 2 5 8 apl-run "M ← (2 3) ⍴ ⍳6 ⋄ M[1 2;1 2]" → 2x2 sub-block	2026-05-07 17:56:24 +00:00
giles	b13819c50c	apl: named function definitions f ← {…} (+7 tests, 467/467) ... Parser: apl-collect-fn-bindings pre-scans stmt-groups for `name ← { ... }` patterns and populates apl-known-fn-names. is-fn-tok? consults this list; collect-segments-loop emits (:fn-name nm) for known names so they parse as functions. Resolver: apl-resolve-{monadic,dyadic} handle :fn-name by looking up env, asserting the binding is a dfn, returning a closure that dispatches to apl-call-dfn{-m,}. Recursion still works: `fact ← {0=⍵:1 ⋄ ⍵×∇⍵-1} ⋄ fact 5` → 120.	2026-05-07 17:33:41 +00:00
giles	d9cf00f287	apl: quick-wins bundle — decimals + ⎕← + strings (+10 tests, 460/460) ... Three small unblockers in one iteration: - tokenizer: read-digits! now consumes optional ".digits" suffix, so 3.7 and ¯2.5 are single number tokens. - tokenizer: ⎕ followed by ← emits a single :name "⎕←" token (instead of splitting on the assign glyph). Parser registers ⎕← in apl-quad-fn-names; apl-monadic-fn maps to apl-quad-print. - eval-ast: :str AST nodes evaluate to char arrays. Single-char strings become rank-0 scalars; multi-char become rank-1 vectors of single-char strings.	2026-05-07 17:26:37 +00:00
giles	aaabe370d6	apl: bracket indexing A[I] → (I⌷A) (+7 tests, 415/415) ... Parser: maybe-bracket helper wraps any value followed by [expr] into (:dyad (:fn-glyph ⌷) idx val). Wired into :name and :lparen branches of collect-segments-loop. apl-run "(10 20 30)[2]" → 20 apl-run "A ← 100 200 300 ⋄ A[2]" → 200 apl-run "(⍳5)[3] × 7" → 21 Multi-axis A[I;J] deferred — needs semicolon-split parsing.	2026-05-07 14:07:05 +00:00
giles	637ba4102f	apl: ⎕ quad-names end-to-end (+8 tests, 408/408) ... Parser: apl-quad-fn-names list; is-fn-tok? + :name clause in collect-segments-loop now route ⎕FMT through fn pipeline. Eval-ast: :name branch dispatches ⎕IO/⎕ML/⎕FR/⎕TS to apl-quad-* niladics; apl-monadic-fn handles ⎕FMT. ⎕← (print) deferred — tokenizer splits ⎕← into name + :assign.	2026-05-07 13:49:35 +00:00
giles	7cf8b74d1d	apl: end-to-end pipeline apl-run + 25 source-string tests (400/400) ... apl-run = parse-apl + apl-eval-ast against empty env. Wires tokenizer + parser + transpile + runtime as one entry point. test.sh now loads tokenizer.sx + parser.sx alongside transpile.sx. Source-string tests cover scalars, strands, dyadic arith, right-to-left precedence, monadic primitives, /, \, ⌈/, ×/, ∘.×, +.×, ⍴, comparisons, classic one-liners. Tokenizer doesn't yet handle decimal literals (3.7 → 3 . 7), so two such tests substituted with integer min/max-reduce.	2026-05-07 13:17:39 +00:00
