Resolves the deferred partition-all port (jolt-yo3). The earlier CLJ attempt via
lazy take/drop over-realized vs the Janet pstep, tripping the §6.3 laziness
counter. The collection arities now realize EXACTLY n per chunk with a first/rest
loop and continue from the advanced cursor (no re-drop), so (take 3 (partition-all
2 (map counting (range)))) realizes exactly 6 — matching minimal realization in
both interpret and compile modes. Keeps transducer + [n coll] + [n step coll]
arities. letfn-bound recursion sidesteps the compile-mode multi-arity closure bug
(jolt-zxw), like keep-indexed/map-indexed.
Removed from the Janet seed: core-partition-all + its binding + the now-dead
td-partition-all helper (the CLJ version carries its own transducer arity).
Gate: conformance 262x3, lazy-infinite 44/44 (incl the §6.3 partition-all
counter), clojure-test-suite 4004/66, fixpoint, self-host, specs+unit green.
Finishes a port the prior team started and reverted (bb4a3e0): the 40-lazy.clj
tier moved lazy seq fns Janet→Clojure but regressed the suite to 849 because
lazy-seq's expansion leaked as data in compile mode — that was jolt-r81, since
root-fixed (lazy-seq/lazy-cat moved to 00-syntax). With the wall gone, the port
works. This shrinks the Janet seed toward the north star (self-hosted
clojure-in-clojure on a minimal host bootstrap).
Moved to core/40-lazy.clj (wired as a loaded tier after 30-macros):
distinct keep keep-indexed map-indexed cycle repeat iterate
40-lazy.clj completed to full parity: distinct gains its transducer arity;
keep/keep-indexed/map-indexed already had both arities.
Removed from the Janet seed (core.janet): the 7 core-* fns + their core-bindings
entries, the now-dead td-keep/td-map-indexed transducer helpers (the CLJ versions
carry their own), and the already-dead core-partition-by/core-xml-seq (shadowed by
10-seq/20-coll). Net: core.janet −131 lines.
Deferred (kept in Janet, separate follow-ups): partition-all (a CLJ port via
take/drop realizes a non-minimal element count, tripping the §6.3 laziness
counters + a suite file) and repeatedly (canonical CLJ doesn't validate args, so
the repeatedly.cljc throw cases regress). Both need behavior-matching first.
Gate: conformance 262x3, lazy-infinite 44/44, clojure-test-suite 4004/66 (UP from
3981 — the CLJ versions add coverage, e.g. distinct value-equality), fixpoint,
self-host, sci 422/0, fallback-zero, specs+unit, core-bench all green.
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.
