Expand java.io so libraries that touch the filesystem work unchanged.
File: the full method surface — length, lastModified, can{Read,Write,Execute},
isHidden, list, mkdir(s), delete, createNewFile, renameTo, getParentFile,
get{Absolute,Canonical}File, compareTo/equals/hashCode — plus the statics
separator / pathSeparator / createTempFile / listRoots. A File now keeps the
path as given (new File("rel").getPath() is "rel", .isAbsolute false); a
relative path resolves against JOLT_PWD only when the filesystem is touched,
matching the JVM. slurp/spit and the dir helpers go through the same
resolution, fixing a spit-vs-slurp inconsistency.
Streams (host/chez/io-streams.ss) — each a jhost wrapping a Chez port, so
buffering, EOF and binary<->char transcoding come from Chez:
- FileInputStream / FileOutputStream / ByteArrayInputStream /
ByteArrayOutputStream / BufferedInputStream / BufferedOutputStream
- FileReader / FileWriter / InputStreamReader / OutputStreamWriter /
BufferedReader / BufferedWriter
Buffered* return the wrapped stream (Chez ports are already buffered).
clojure.java.io: input-stream/output-stream now yield real byte streams (were
aliased to the char reader/writer); added copy (byte-exact for byte sources),
make-parents, delete-file. with-open also closes file-writer/port-writer/
print-writer (a pre-existing gap).
All runtime shims, no re-mint. 15 JVM-certified corpus rows; make test +
shakesmoke green.

Chez test harness
The correctness gate for jolt. Pure Chez (+ Clojure for the JVM oracle).
Correctness is judged against the JVM-sourced conformance spec; the spec itself
lives in test/conformance/ (see its SPEC.md). Run the whole gate with make test from the repo root.
The spec corpus
corpus.edn is the contract: ~2920 rows {:suite :label :expected :actual}, with
:expected sourced from reference JVM Clojure by test/conformance/regen-corpus.clj.
It is frozen (the canonical source) — add or change cases here, then re-source the
answers with regen-corpus.clj and re-certify with test/conformance/certify.clj.
The gate runners (host/chez/)
-
run-corpus.ss— runs every corpus case through the spine (read → analyze → IR → emit → eval, all on Chez), comparing each result by value-equality against the JVM:expected. Aknown-failallowlist covers cases jolt can't match because Chez has no JVM host (Java classes, arrays,BigDecimal, opaque host-object printers, …); the gate fails only on a NEW divergence or if the pass count drops below the floor.chez --script host/chez/run-corpus.ss JOLT_CORPUS_LIMIT=200 … # every-Nth stride, fast iteration JOLT_CHEZ_ZJ_FLOOR=N … # override the floor (default 2678) -
run-unit.ss— host-specific unit cases (test/chez/unit.edn) that aren't in the JVM-portable corpus: dot-forms, java statics, io, reader, walk, vars/namespaces, refs. Each:expris evaluated in-process and its printed value compared to a baked:expected(:throwsasserts a raise). -
selfcheck.sh— self-host fixpoint:bootstrap.ssrebuild byte-equals the checked-in seed (host/chez/seed/). -
smoke.sh— realbin/joltc -eCLI smoke.
Other Chez tests
values-test.ss— the value model (nil/truthiness/collections).make values.bench-chez.ss— compute bench through the pipeline (opt-in; not in the gate).
All runners assume chez on PATH.
