Rename src/jolt -> stdlib (the runtime-loaded layer; jolt-core stays the
seed-baked layer) and update the loader / emit-image / doc paths. Drop dead
code: the spike/ experiments, the duplicate clojuredocs-export.edn (json moves
to tools/), the Janet-era jolt.http binding, and the orphaned
persistent_vector.clj whose ns/path didn't even match.
Strip porting residue from comments and docstrings across host/chez, jolt-core,
stdlib, tests, and docs: internal issue ids, "Phase N" markers, and the "vs
Janet" historical exposition, leaving present-tense descriptions and the real
JVM-Clojure semantic contrasts. Same pass over the corpus suite labels. The seed
is unchanged (docstrings/comments aren't emitted), so the self-host fixpoint and
corpus are untouched.
Port tools/spec_coverage.py off the dead janet probe to bin/joltc and regenerate
coverage.md; drop the dead :host/janet rule from certify.clj and regenerate the
conformance profile. Add docs/host-interop.md (the JVM shims and how to register
your own host class from a library) and a writing-style note in CLAUDE.md.
Stabilize the four racy concurrency corpus cases (future-cancel and agent
send/send-off): give the future a sleeping body and the agent a slow action, so
cancel reliably catches an in-flight future and deref reliably reads the
pre-update snapshot. They certify deterministically now, so drop their :flaky
allowlist entries and the orphaned legend.
Rephrase comments that pointed at deleted Janet files (emit.janet, the seed
sources, 'the Janet back end punts ...') to present-tense descriptions of the
Chez behavior. Comment/docstring-only; the self-host fixpoint is unchanged
(comments don't affect the compiled seed).
Delete five files that were Janet-host shims with no Chez path: clojure.java.io
(provided natively by host/chez/io.ss), and jolt.{nrepl,png,interop,shell}
(the janet.* bridge, os/shell, janet.net — none exist on Chez).
jolt-cf1q.6
Add a thread-safe delay type (concurrency.ss): make-delay wraps a thunk; deref/
force run it once under a lock and cache (JVM delays are thread-safe + memoized).
delay? and realized?-on-a-delay are native; the overlay's `delay` macro
(-> make-delay) and `force` (-> deref) now work. realized? wrapper (post-prelude)
and the deref chain gain a delay arm. Removed the np-delay? stub from
natives-parity.ss (the real type lives in concurrency.ss).
Seed unchanged (no re-mint). zero-Janet 2673->2685, 0 new divergences; Janet gate
+ JVM cert green.
jolt-cf1q.7
host/chez/natives-array.ss: a jolt-array over a mutable Chez vector + object/typed
constructors (object-array/int-array/.../byte-array/make-array/into-array/to-array/
aclone), typed aset-*, byte/short coercions, bytes?/bytes/ints/..., and eager
chunk-buffer/chunk-* (Jolt doesn't chunk). count/nth/seq/get and jolt.host/ref-put!
are extended to see a jolt-array, so the overlay's aget/aset/alength work over it.
Numbers it produces are flonums (jolt's rep) so exactness-aware = holds. char-array
stays in io.ss (a char-SEQ that io/reader/str/slurp consume).
natives-parity.ss adds: __reader-features / -set!, reader-conditional, re-matcher,
delay? (stub — no delay type yet), macroexpand / macroexpand-1 (via the host-contract
macro seams).
A Chez array is a DISTINCT object (= the JVM), not a seq, so comparing a BARE array
to a list diverges from the Janet array-as-seq stub — those cases are allowlisted on
both gates (element ops aget/aset/alength/seq/vec pass). zero-Janet 2600->2642,
prelude 2590->2629, 0 new divergences; Janet gate + JVM cert green.
jolt-cf1q.7
Native Chez shims for clojure.core fns that live in the Janet seed but had none
on the zero-Janet spine (they resolved to nil -> "not a fn"):
- host/chez/natives-parity.ss: hash / hash-combine / hash-ordered-coll /
hash-unordered-coll (24-bit masked like core_extra), transient?, rseq (vectors +
sorted colls), cat (transducer).
- jolt-invoke now dispatches a TRANSIENT vec/map/set as a fn (callable on the JVM):
((transient [10 20 30]) 1) -> 20.
- ns.ss: ns-resolve, ns-imports, remove-ns, intern, alias, ns-unalias, refer,
ns-refers, refer-clojure, alter-meta!, reset-meta!, and a real ns-aliases (was a
stub returning {}).
- runtime (require ...)/(use ...) now register :as/:refer into the Chez ns tables
(was a no-op). The Chez analyzer already pre-registers at analyze time, but when
the JANET analyzer compiled the form (prelude path) the Chez tables stayed empty,
so ns-aliases/ns-resolve over an alias diverged — this fixes both paths.
Seed unchanged (overlay doesn't reference these at mint time). zero-Janet corpus
2567->2600, prelude 2557->2590, 0 new divergences on either; Janet gate + JVM cert
green. Filed jolt-vgrp for the pre-existing var-get-of-scalar-native-op quirk.
