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.
Surfaced running the DB libraries (migratus) on the jolt db library:
- java.sql.SQLException .getNextException / .getStackTrace / .printStackTrace on
jolt throwables (conditions + ex-info) return nil/empty, so a library walking
the exception chain doesn't crash.
- java.net.URL ctor + .getProtocol (file/http), alongside the existing url shim.
- A generic java.lang.ClassLoader: getSystemClassLoader / a thread's
contextClassLoader resolve a named resource against the source roots (the same
model as clojure.java.io/resource) — file: URL or nil. Thread/currentThread.
These are generic host capabilities, not DB-specific.
The jolt-lang/db next.jdbc surface now runs migratus far enough to connect, build
the migrations table, and discover migrations; migratus's remaining dependency is
java.nio.file (FileSystems/Path/PathMatcher glob), a JVM filesystem API kept out
of core.
Shake-out from the conformance-library sweep. Host-side fixes (runtime .ss,
no re-mint) plus one analyzer change (re-minted):
- Exception fidelity: ex-info and host-constructed throwables (RuntimeException.
etc.) now carry their JVM class, so (class e), instance? across the exception
hierarchy, .getMessage, and clojure.test thrown?/thrown-with-msg? all work.
- .getBytes returns a seqable/countable byte-array and honors UTF-16/UTF-32;
String. decodes them. ->bytevector accepts byte-arrays (Base64).
- Universal .getClass / .toString / .indexOf / .lastIndexOf on any value/seq.
- record? uses the host jrec? predicate (the old (get x :jolt/deftype) crashed
on a sorted-map by invoking its comparator).
- extend-protocol to abstract host types (clojure.lang.Fn/IFn/APersistentVector,
java.net.URI) dispatches.
- New host classes: clojure.lang.PersistentQueue, java.util.ArrayList,
java.net.URI, java.io.File / java.util.UUID ctors, Double/Float ctors+statics,
regex instance? Pattern, System/setProperty.
- *assert* / *print-readably* are real settable/bindable vars.
- (symbol "ns/name") splits the namespace at the last slash.
- letfn fn params desugar destructuring (analyzer; re-minted).
unit.edn gains exinfo/hostobj/queue/hostctor/destructure regression rows.
malli loads and validates now. Three divergences surfaced building its registry
and :map schema:
dot-forms: (.iterator coll) on a map fell into the map-as-object branch and was
mis-read as a missing :iterator key (nil), so malli's -vmap got nil and crashed
on .hasNext. Route iterator through the collection-interop path — a jiterator
over the seq (the entry iterator for a map).
host-static: register clojure.lang.LazilyPersistentVector/createOwning (-vmap
fills an object-array then hands it over) and PersistentArrayMap/createWithCheck
(malli's eager entry parser relies on its duplicate-key throw; a missing class
was caught and mis-reported as ::duplicate-keys on every map schema).
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
The analyzer lowers the `.` special form (. target member arg*) and the
.-field field-access head to a :host-call instead of leaving them
uncompilable. Janet behaviour is unchanged — its back end punts :host-call
to the interpreter, which re-runs the original `.` form via eval-dot.
The Chez back end routes a non-shimmed :host-call through
record-method-dispatch, extended by a new host/chez/dot-forms.ss with the
arms dispatch-member covers but the record/string base did not, mirroring
src/jolt/interop/collections.janet precedence:
- collection interop first (count/seq/nth/get/valAt/containsKey on a
vector/map/set), so (. {:count 9} count) is the entry count like the seed
- field access for a "-name" member (records and maps)
- the seed's universal object-methods (getMessage/getCause/toString/
hashCode/equals) on a non-record map, winning over a field lookup
- non-record map member: a stored fn is a method called with self, else
the field value
Raw seqs are excluded from coll interop — the seed's behaviour there is
representation-dependent (plain (seq v) vs a lazy-seq) and a normalized cseq
can't mirror it. Also added getMessage/getLocalizedMessage/equals to the
string method surface so a thrown string / Exception. ctor (which keeps the
message string) answers .getMessage.
Parity 2134 -> 2150, 0 new divergences. New test/chez/_dotform.janet 26/26;
emit-test 331/331.
