merge now throws when a non-first arg is a scalar, a set, a list, or a
wrong-length vector (a length-2 vector or a map still merge). Other map-like
tables (records/sorted-maps/host tables, e.g. SCI's namespaces) keep the lenient
conj path so the SCI bootstrap still loads.
merge 29/11/2 -> 35/3/4. clojure-test-suite pass 3874->3880.
spec: 5 merge strictness cases. jpm test green.
- assoc on a vector bounds-checks the index (0..count); out-of-range/negative throw
- dissoc throws on non-maps (numbers/sequences/sets/scalars); nil ok; records/
sorted-maps/meta-maps still handled
- count throws on scalars (numbers/keywords/symbols/booleans/chars)
- subvec validates vector type and 0<=start<=end<=count
- numerator/denominator always throw (Jolt has no ratio type)
- min-key/max-key throw on no values
count 18/2; dissoc 19/3; assoc 36/6; subvec 26/3/5; numerator/denominator throw
cases pass. clojure-test-suite pass 3840->3864. spec: map/strictness (16). jpm test green.
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.
