The printer's two entry points (jolt-pr-str in rt.ss, jolt-pr-readable in printing.ss)
get register-pr-str-arm! / register-pr-readable-arm!, plus register-pr-arm! for the
types whose str and readable forms match (bigdec/inst/uuid/tagged/record/ns/var). The
normalize arms (sorted, lazy-seq, queue) and the uri readable arm register per-printer.
Also folds in the hash (dyn-binding var-cell), class (io uri/uuid/file), and get
(transients) arms missed earlier.
natives-array's get stays a case-lambda wrapper on purpose: its 2-arg path errors on
an out-of-bounds index while the 3-arg path returns the default, an arity distinction
the (coll k d) registry collapses — left as-is to preserve behaviour.
Completes jolt-lmot: all six dispatchers (hash/class/get/=/pr-str/pr-readable) off the
set!-rebind chains. make test green, 0 new corpus divergences; pr-str/str of inst,
uuid, bigdec, sorted-map, record-with-lazyseq, queue all verified.
Replace the set!-capture-and-rebind chains extending jolt-hash (3 sites: inst-time/
host-table/records) and jolt-class (3 sites: bigdec/natives-queue/host-table) with a
register-hash-arm! / register-class-arm! registry (the pattern already used by
register-str-render!). The base dispatcher walks its arms — disjoint types, so order
is immaterial — then falls to the base cases. The entry is stable, so the per-site
(def-var! "clojure.core" "class" …) re-points are gone.
Behaviour-preserving (runtime .ss, no re-mint): jinst hash, bigdec/queue/record
class, record hash, and a sorted-map hashing as its plain map all verified; make test
green, 0 new corpus divergences. First two of six dispatchers; get/=/pr-str follow.
jolt-str-render-one and instance-check were each extended by a chain of
set!-wrapping closures spread across ~10 and ~5 host files, so the real
behavior of either was scattered and load-order-dependent. Give each a
registry the base file owns: converters.ss/records-interop.ss define the
registry plus a register-* helper, and each extending file registers one arm
instead of capturing %prev and set!-ing the global.
str-render arms are type-disjoint; instance-check arms run newest-first (the
old outermost-wins order) and may return 'pass to defer. The string-token ->
symbol normalization the natives-array arm did for every inner arm moves to
the dispatcher head; array tokens stay strings for that arm to decide.
jolt-ogib.14. Runtime-only shims, no re-mint.
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.
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.
