Round 4 of the seed shrink. zero?, pos?, every? move to the syntax tier
(empty? and the analyzer use them — raw def+fn* per the file constraint);
char? joins the tagged-value predicates in 20-coll. coll? stays seed: host
set? doesn't cover sorted sets (filed jolt-dpn) and the tag check from the
overlay would hit the sorted-coll get trap. pos? guards number? explicitly —
the staged recompile emits bare > as the native janet op, which orders
strings (zero? gets the same guard; spec rows lock both plus neg?).
The canonical every? seq-walks its coll, which exposed that rest/next over
sets, phms, struct maps and sorted colls fell into core-rest's indexed
fall-through and walked the wrapper table's INTERNAL fields — (next #{1 2})
was (nil nil), (clojure.set/subset?) broke. core-rest now seqs those
representations (branches placed AFTER the hot vector/lazy paths; the first
ordering cost seq-pipe 4x). Suite rises 4700 -> 4703; baseline 4660 -> 4695.
even?/odd? are back in the seed after the bench A/B: (filter even? ...) pays
an extra call layer per element through the overlay (seq-pipe 262 -> 1100ms).
They join the perf-wall list with the lazy hot fns.
Loading these libs via require worked (load-ns-source interprets, macros
expand lazily) but the same code inlined by uberscript routes through
eval-toplevel and compiled, surfacing four gaps:
- a ^{:map} metadata def name reads as (def (with-meta name m) v); the
analyzer died extracting the name (config.core's defonce env). It now
throws uncompilable so the interpreter, which handles it, takes over.
- declare was a no-op, so a compiled forward reference to a declared
name that collides with a janet root binding bound to the host fn
(selmer.parser's (declare parse) compiled to janet's 1-arg parse).
declare now expands to no-init defs, the interpreter interns them,
and the analyzer routes no-init def to the interpreter.
- class? was missing (selmer.util's exception macro calls it at
expansion time). Always false, like ratio? — no Class objects here.
- require of an unlocatable namespace silently left an empty ns behind,
deferring the failure to an unresolved symbol far from the cause. It
now throws like Clojure's FileNotFoundException. Namespaces entered
in-session count as loaded (Clojure puts them in *loaded-libs*), and
the SCI bootstrap opts out via :lenient-require? since its
clj-targeted requires can't all exist on this host.
ifn? (jolt-1vx) is the canonical IFn set in the overlay: fns, keywords,
symbols, maps (sorted included), sets, vectors, and vars — NOT lists. The
seed version said true for lists and false for struct maps and vars.
Mutable-mode caveat documented (vectors and lists share the array repr
there). 13 predicate rows.
Multimethod dispatch (jolt-heo) now collects EVERY isa-matching method key
and picks the dominant one — x dominates y when prefer-method'd over it or
(isa? x y) — and two matches with no dominant is an ambiguity ERROR, as in
Clojure. It used to take whichever key the table yielded first, silently
ignoring prefer-method. The prefers store upgrades to Clojure's
{x -> set-of-dominated} shape, shared between the dispatch closure and
prefer-method-setup via the var; prefers becomes a macro over a setup fn
(the store lives on the VAR — the multifn value can't carry it, so the old
fn read {} forever). 6 multimethod rows + the conformance row updated to
the canonical shape (335x3).
The reader (jolt-ou8) kept the pending KEY when a comment or #_ sits in a
map's VALUE slot: the old code dropped both, desyncing kv pairing — the
real value became the next key and the closing brace landed in value
position ('Unmatched closing brace'). Selmer's deps.edn (a '; for
development (REPL, etc)' comment between key and value) now parses; 6
reader rows incl. nested commented maps.
Gate: jpm exit 0, conformance 335x3, all tests passed.
resolve-sym's last resort silently resolved any unknown Clojure symbol
against Janet's root environment — leaking Janet builtins with JANET
semantics into Clojure code: (type 1) was Janet's :number, (gensym) returned
Janet symbols (the long-documented (symbol (str (gensym))) macro landmine
existed BECAUSE of this), compare/slurp/int?/any? likewise. The explicit
janet/ prefix is the deliberate interop channel; the implicit fallback is
gone — an unresolved symbol is an error.
What the leak was masking, now proper interned vars:
- gensym: jolt's own (already existed, never interned) — returns real jolt
symbols; the macro landmine is dead
- compare: full Clojure total order (nil-first, numbers, strings, keywords,
symbols by ns/name, booleans, chars, uuid/inst, vectors by length then
elementwise; cross-type throws)
- type: :type metadata override, deftype/record tag as symbol, else a
taxonomy keyword (host-classified)
- int?: core-integer? — which had a latent bug the leak hid: (integer?
##Inf) was true (floor of inf is inf); NaN/infinities now excluded
- any?: constantly true (Clojure 1.9; SCI's namespaces.cljc needs it)
- jolt.interop/janet-type now uses the explicit (janet/type x) channel
- evaluator-test uses init (a bare make-ctx resolved EVERYTHING via the leak)
Suite 4470 -> 4532+ pass / 86-87 clean (proper compare unlocks the sort
files); baselines raised. Conformance 326x3 (+5 rows), +22 predicate spec
rows, stdlib battery green, all specs+unit. Coverage dashboard now counts
previously-leak-resolvable names honestly (missing-portable 19 -> 27).
map? treated ANY struct as a map, so (map? 'sym), (map? \a), and
(map? (random-uuid)) were all true; coll? had the same wart. Meanwhile both
were FALSE for sorted maps (and coll? for sorted sets and records), which are
collections in Clojure. Now: a map is a plain struct literal, a phm, a sorted
map, or a record; coll? additionally includes sorted sets. Tagged structs
(anything with :jolt/type) are values.
The loose-map? dependents (destructure's clause ordering, defn's attr-map
guard) already guarded with symbol? first, so nothing relied on the wart —
full gate green, and the suite gained: 4074 -> 4081 pass / 72 clean files
(map_qmark/coll_qmark assertions now correct); baselines raised. 22 new
strictness spec cases.
* core: fix jolt-265 — syntax-quote fully-qualifies core syms to clojure.core/
Re-attempt of the deferred gap, now unblocked. The earlier uberscript break
wasn't qualification itself but an aliased-ref resolution bug it exposed:
resolve-var looked up ns-aliases (e.g. g/foo) against the analyzer's REBOUND
ctx-current-ns (jolt.analyzer, since the analyzer runs interpreted in its own
ns) instead of the namespace being compiled. A user's aliased refs failed
mid-compile (g/hello -> nil in the bundled standalone).
- resolve-var resolves aliases against :compile-ns when set (same ns
h-current-ns uses), falling back to ctx-current-ns — correct for both modes.
- sq-symbol qualifies a resolved clojure.core name to clojure.core/<name>
(Clojure hygiene); special forms stay bare; unresolved syms -> current ns.
Tests updated to the qualified behavior (features-test, reader-forms-spec).
* test: comprehensive spec — regex + sorted colls + random/predicate gaps
Filling the biggest untested clojure.core areas found in a coverage audit
(168 of 506 provided fns had no spec). New + expanded suites:
- regex-spec.janet (20): #"…" literals, regex?, re-find/re-matches/re-seq
(match/no-match/groups), re-pattern, and clojure.string split/replace with
regex (incl $1 backrefs). Whole area was previously unspecced.
- sorted-spec.janet (14): sorted-map/sorted-set construction + ordering, sorted?,
subseq/rsubseq. Pins the working subset — get/conj/assoc/keys/vals on sorted
colls and the by-comparator ctors are not yet first-class (jolt-ti9).
- predicates-spec +14: seqable?, integer?, reduced?/unreduced, not-empty.
- numbers-spec +5: rand/rand-int/rand-nth invariants.
Fix: sorted? was bound to core-sorted-map? so it returned false for sorted-sets;
now true for both sorted maps and sets (core-sorted?).
Filed: jolt-ti9 (sorted collections incomplete: get/conj/assoc/keys/vals don't
operate on the sorted wrapper; sorted-*-by ignore the comparator).
Gate green incl full jpm build + jpm test.
* core: close surfaced gaps — first-class sorted colls, with-out-str, rand arity, deref reduced
jolt-ti9: sorted-map/sorted-set are now first-class across the collection fns —
get/assoc/dissoc/conj/contains?/keys/vals/disj and call-as-fn all operate on the
wrapper and preserve sort order. The by-comparator constructors (sorted-map-by/
sorted-set-by) now thread the user comparator (numeric or boolean-predicate) through
all derived colls. Sorted predicates/ctors/ops moved above core-conj so the
collection fns can branch on them; jolt-invoke (interpreter) gets inline branches.
jolt-rfw: add with-out-str (binds output to a string buffer) + the macro.
jolt-ek3: (rand n) arity and deref-of-reduced (uuid? still deferred).
Specs: new io-spec.janet; sorted-spec expanded to pin the now-working map/set ops
and by-comparator ordering; predicate/number spec restorations.
* remove old doc
* core: fix stale comment — by-comparator sorted ctors are implemented

adds self-hosted compiler is functionally:
- The default compile path is the portable pipeline using jolt.analyzer (Clojure) → host-neutral IR → backend.janet.
- The analyzer is itself Clojure, compiled by jolt for true self-hosting.
- bootstrap-fixpoint passes (stage1 == stage2 == stage3): rebuilding the compiler on its own output.
- clojure.core is now self-hosted in the overlay.
- Stateful forms (defmacro/ns/deftype/defmulti/require/in-ns) are interpreted by design.
- case: quote list literals (read as arrays) in constant position so a wrapped
list ((a b c)) matches by value instead of being evaluated as a call; symbol
constants already quoted. Vector/map/set constants already worked. case errors
in the suite drop to 0 (60 pass).
- associative?: true only for vectors (pvec) and maps (phm/struct/sorted-map),
not lists/tuples-from-seq-fns/lazy-seqs/sets.
- reversible?: true for vectors and sorted-map/sorted-set only.
- update: coerce f via as-fn so (update m k :kw)/(update m k a-set) work; extra
args already handled.
- nth: (nth nil i)/(nth nil i default) returns nil/default instead of throwing.
clojure-test-suite pass 3649->3678, errors 122->105, clean files 44->46.
associative?/reversible? files now fully clean. spec: predicates + control/case.
jpm test green.
Mine the cljs port batteries into the spec layer and delete them (their behavior
is covered by spec; the unique functions they exercised are now specced).
Removed test/integration/ports/ entirely.
New/expanded spec coverage from the mining:
- spec/exceptions-spec: try/catch/finally, throw, ex-info/ex-message/ex-data/ex-cause
- doto, pr-str, keyword/symbol constructors, atom?, dynamic var binding
Two rare edges filed (jolt-...): rethrow of a caught ex-info re-wraps it; var-set
on a dynamic var inside binding no-ops. Core try/catch/ex-info and binding work.
Test layout is now spec (22 files, ~677 cases) / integration / unit / support.
conformance 218/218, jpm test green.
Add spec suites for numbers/arithmetic, strings (str + clojure.string), and
type/value predicates. Bugs they caught and fixed:
- <, >, <=, >= were binary-only; now variadic ((< 1 2 3) chains)
- seq? was true for vectors; vectors are not ISeq in Clojure, so (seq? [1])
is now false (true only for lists/lazy-seqs)
- clojure.string/index-of and last-index-of were 1-based (stray inc); now
0-based per Clojure
Corrected a systematic-coverage assertion that encoded the old seq? bug.
jpm test green, conformance 218/218.
