Three canonical-conformance fixes from the post-shrink batch:
- bit-and/bit-or/bit-xor/bit-and-not get Clojure's variadic arities as
20-coll shells folding the binary host ops (now __bit-* seams). 2-arg call
sites still compile to the native janet op via the backend's native-ops
table. The passes.clj constant-fold table now names the seams — the public
fns are overlay and don't exist when the compiler loads (this briefly broke
every compile-mode init).
- core-set? recognizes the :jolt/sorted-set representation (jolt-dpn):
(set? (sorted-set 1)) was false, and ifn? on sorted sets inherited the bug.
- (if) / (if test) / (if test then else extra) throw in both the analyzer
and the interpreter — spec 03-special-forms X1, now marked verified.
Suite 4704 -> 4706; bench and the greeter example benchmark are flat.
sorted-map/sorted-map-by/sorted-set/sorted-set-by/sorted?/sorted-map?/
sorted-set?/subseq/rsubseq now live in their own overlay tier (25-sorted.clj).
A sorted coll is a tagged host table with a comparator-ordered :entries
vector, a 3-way :cmp, and the tier's op implementations ATTACHED to the value
(:ops map): the seed's conj/assoc/get/seq/count/... branches are each a
one-line call through (coll :ops), so the ops travel with the value — correct
across contexts, forks, and AOT images, no module-level hooks to re-wire.
The host surface grows by three minimal value primitives: jolt.host/
tagged-table, ref-put! (already there), and ref-get — a raw field read,
because plain get on a sorted coll IS the comparator lookup and reading
:entries with it recurses.
This fixes a pile of Clojure-correctness gaps the Janet kernel had:
- lookup/membership now go through the COMPARATOR: (contains? (sorted-set 1)
1.0) was a deep= scan, (conj (sorted-set 1) 1.0) and assoc of a
comparator-equal key now no-op/replace as in Clojure
- equality is representation-agnostic: (= (sorted-map :a 1) {:a 1}) and
(= (sorted-set 1 2) #{1 2}) were false
- iteration was broken: (map inc (sorted-set 3 1 2)) errored
(realize-for-iteration and coll->cells had no sorted branches)
- empty?/empty saw the host wrapper, not the collection: (empty? (sorted-map))
was false, (empty sc) returned a bare table; it now keeps the comparator
- sorted colls canonicalize as map keys; comparator fns may be boolean
predicates or 3-way (Clojure's fn->comparator)
- sorted-map throws on odd kv count; conj nil is a no-op
Also fixes jolt-h86 en passant: into-conj had no branch for sets (or sorted
colls) and silently returned the target unchanged — (into #{} [:a :b]) was
#{}. The fallback now folds conj. Regression rows in sets-spec.
sorted-spec grows to 77 rows (comparator-based membership, equality,
empty/rseq/printing, seq-fn interop, subseq/rsubseq on maps). Gate green:
conformance 326x3, suite 4577 (vs 4566 prior — the battery gained rows),
sorted+sets specs, full jpm test, bench at parity with main back-to-back
(4521ms vs 4619ms TOTAL under identical load).
Close jolt-do7. Maps/sets keyed by a collection (a map, vector, ...) now compare
by value instead of Janet identity:
- PHM/PHS hash and compare keys through an injected canonicalizer (collection
keys -> value-hashable struct/tuple); keys are still stored as-is
- map literals and core-assoc promote to a phm when a key is a collection
- frequencies/group-by use a phm base so collection elements/keys dedup by value
- set equality is value-based (from earlier)
Real bugs found and fixed along the way:
- set literals #{(inc 1)} did not evaluate their elements (stored raw forms!)
- the REPL printer rendered phm maps as {} (they hit the deftype branch); now a
phm branch prints entries
Added spec cases (maps/collection-keys, sets/literals & value elements).
conformance 218/218, jpm test green.
Add behavioral spec suites for the collection API (~180 cases). Writing them
surfaced and fixed real bugs:
- (count nil) errored; now 0 (Clojure semantics)
- (repeat x) and (repeatedly f) — the infinite 1-arg arities — were unsupported;
now return lazy infinite seqs
- set equality used deep= (representation-sensitive), so a set of map literals
could differ from an equal set built differently; now value-based (each
element value-equal to some element of the other)
Known limitation filed: phm-typed maps (from hash-map) used as set elements /
map keys hash by identity (map *literals* are structs and work).
jpm test green.
