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.
(type r) returned a symbol user.TyR, so (= (symbol (str (type r))) (type r))
was true; the JVM's type is a Class (not a Symbol) so it's false. jolt models
classes as strings, so a record's type is now its ns-qualified class-name
string — equal to (class r), as on the JVM where type and class coincide for a
record. The symbol-keyed print-method defmethods already fall through to the
default record printing, so they're unaffected. Closes type-of-record.
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
Implement (type x) on the Chez RT (host/chez/natives-meta.ss). Mirrors the
seed's core-type: the :type metadata wins when present, a record yields its
ns-qualified class-name SYMBOL (user.TyR — no-ns sentinel #f so it = the
overlay's (symbol (str t))), everything else a host-taxonomy keyword
(:number/:string/:vector/:map/:set/:seq/:fn/…). Total by construction — a
non-record value falling through to a crash would read as a divergence, so the
cond covers every value type incl. the host wrappers (atom/volatile/regex/var/
transient/uuid -> :jolt/*, a :jolt/type-tagged map like ex-info -> its tag,
sorted-set -> :jolt/sorted-set, sorted-map -> :map) and a final :object.
Also pin sequential?/seq? on lazy seqs (test/chez/_seqpred.janet): the inc M
seq? re-def-var! fix already covers sequential? transitively (sequential? is
overlay and delegates to seq?), so no code change — the earlier "still broken"
note was wrong, it assumed sequential? was native like seq?.
Prelude corpus parity 2000 -> 2002 (the two type cases), floor raised, 0 new
divergences. Gate: _type 37/37 + _seqpred 22/22 (both vs build/jolt oracle),
emit-test 321/321, full jpm test, conformance 355x3.
Capture a def's reader metadata on the Chez var. The :def emit now lowers a def
with non-empty metadata to def-var-with-meta!, which stores the user meta
(^:private / ^Type tag / docstring -> {:doc}) in an eq side-table keyed by the
var-cell. jolt-meta of a var-cell merges that onto {:ns :name} derived from the
cell, so every var reports {:ns :name} like Clojure with the def-time meta
layered on. (^{:map} metadata on a def name stays uncompilable for the compiler
generally — analyzer rejects it, the Janet back end punts to its interpreter,
which Chez lacks — so it's out of subset, not a meta-capture gap.)
Added natives-meta.ss to the prelude-cache fingerprint. Prelude parity
1969 -> 1972, 0 new divergences; the three var-metadata allowlist entries
(^:private / ^Type tag / docstring) dropped. New focused gate
test/chez/_var_meta.janet.
meta/with-meta resolved to jolt-nil. Chez values don't carry metadata, so
collections use an identity-keyed side-table: with-meta returns a fresh copy of
the value (new identity) and records its meta there, leaving the original
unchanged (immutable-with-meta) and dropping meta on a later copying op. Symbols
carry meta in their existing field; meta on a non-metadatable value is nil.
vary-meta works over these. with-meta on a fn stays fn? (jolt is lenient).
emit.janet carries a quoted symbol's reader metadata (^:foo bar) onto the
emitted jolt-symbol so (meta 'x) sees it; symbol = still ignores meta.
Prelude parity 1701 -> 1723, 0 new divergences. jolt-rkbc.
