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.
Gaps the clj-http-lite suite hit running over jolt-lang/http-client:
- with-open now closes a tagged-table stream shim via its .close method (was a
:close field lookup that only matched the Janet-era tables).
- slurp accepts a bytevector / jolt byte-array / a byte input-stream shim and
honors :encoding — clj-http-lite slurps response bodies and :as :stream bodies.
- (.getBytes s charset) and Charset/forName respect the charset (ISO-8859-1 etc.,
one byte per char), not always UTF-8; Charset/forName returns the name string.
- (class e) reads the JVM :class off a throwable tagged-table, so clojure.test's
(thrown? Class …) / (= Class (class e)) match a library's typed exceptions.
- Registered the HTTP/IO exception class names (IOException, UnknownHostException,
SocketTimeoutException, SSLException, …) so the FQ literals self-evaluate.
All runtime .ss shims, no re-mint. Full gate green.
sorted-map seq/first/entries built plain [k v] vectors, so map-entry? was false
and key/val threw. Build them via a new jolt.host/map-entry seam (entry-flagged
pvec), matching a regular map's entries. Re-minted.
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
jolt was all-flonum (one :number type, inherited from Janet whose only number
type is a double). The Chez runtime has a full numeric tower, so the zero-Janet
path now carries it = JVM Clojure semantics:
(/ 1 2) => 1/2 (exact Ratio, was 0.5)
(integer? 3) => true (integer? 3.0) => false (float? 3.0) => true
(ratio? (/ 1 2)) => true (= 3 3.0) => false (== 3 3.0) => true
(+ 1 2) => 3 (exact) (/ 1.0 2) => 0.5 (double)
jolt= was already exactness-aware (values.ss) and == is value-equality, so
=/== match the JVM split. The reader preserves exactness (integer literals exact,
a/b ratios exact rationals, decimals/exponents flonums); backend_scheme emit-const
renders exact ints/ratios and flonums faithfully; the value-position arithmetic,
count, int, compare, bit ops, parseLong, string .length/.indexOf, range,
timestamps, and array bytes return exact integers (= JVM int/long) instead of
coercing to flonum. double/parseDouble/clojure.math floor|ceil|signum stay double.
Only the zero-Janet path carries the tower (the Janet reader loses exactness into
a double before emit). The prelude/all-flonum path is unaffected for compiled code;
the runtime reader is shared, so a couple of all-flonum reader assertions become
value (==) assertions. ~16 numeric corpus cases now give the JVM tower value vs the
Janet-era :expected and are allowlisted as tower divergences (Chez == reference
JVM) pending the corpus flip to JVM (jolt-ecz0). No BigDecimal type (1M).
Re-minted. zero-janet 2682 (floor 2698->2682, the reclassified tower cases), 0 new
divergences; fixpoint 10/10, bootstrap 6/6, spine 35/35, cli 49/49; Janet gate 155
files 0 failed.
jolt.host/tagged-table, ref-put!, ref-get resolved to jolt-nil on the
prelude, so the 25-sorted tier and every overlay fn that calls sorted?
(empty, ifn?, reversible?, map?, set?, coll?) hit apply-jolt-nil.
host-table.ss provides the three primitives over a Chez mutable htable
record and set!-extends the collection dispatchers (seq/count/get/
contains?/assoc1/dissoc/conj1/disj/empty?/keys/vals/coll?/map?/set? +
printers + equality + value-host-tags) with a sorted arm routing through
each value's :ops table — the seed dispatch pattern, same as records.ss.
first/rest/next fall out free since they seq first. Sorted colls print
in sorted order ({k v, k v} for maps) and = canonicalize like their
unordered counterparts.
emit.janet: a computed call operator (an :invoke/:if expr that yields an
IFn, e.g. ((sorted-map :a 1) :k)) now routes through jolt-invoke instead
of a raw Scheme application.
Prelude parity 1723 -> 1837, 0 new divergences. Floor raised to 1837.
