Running clojure.tools.reader's own suite on jolt surfaced a batch of general
gaps (all runtime, JVM-certified, no re-mint — reader.ss is loaded at runtime
and jolt-core has no octal literals, so selfhost holds):
Reader:
- (load "rel") resolves a non-/ path against the current namespace's directory,
like Clojure — (load "common_tests") from clojure.tools.reader-test loads
clojure/tools/common_tests.clj. Was resolved against the roots directly.
- Octal integer literals: 042 reads as 34, not decimal 42; octal string escapes
(\377 is one char, not \0 + "00"). \oNNN char octal already worked.
- (symbol nil name) now equals (symbol name) and the reader literal — a nil
namespace is the #f no-ns sentinel, not jolt-nil (jolt= compares ns by equal?).
clojure.test:
- thrown-with-msg? honors the class hierarchy (instance?) before falling back to
a simple-name match, so (thrown-with-msg? RuntimeException ...) matches an
ExceptionInfo, like thrown? already did.
Host interop (java layer):
- java.util.regex: Pattern.matcher / Matcher.matches / .group / .groupCount /
.find, and Pattern/compile.
- clojure.lang: RT/map, PersistentList/create, PersistentHashSet/createWithCheck.
- java.lang.Character: digit / isDigit / isWhitespace / valueOf.
- java.util.LinkedList (Deque surface over the ArrayList backing); ArrayList /
LinkedList are now seqable.
- BigInteger 2-arg ctor (string, radix) + .negate / .bitLength / .signum / .abs;
BigInt/fromBigInteger and Numbers/reduceBigInt (identity on jolt's exact ints).
Suite: reader_test 22/30, reader-edn_test 13/16. The remaining failures are
fundamental numeric-model differences (no BigDecimal type; BigInt and Long are
one exact-integer type) or need JVM reflection (record/ctor tagged literals via
getConstructors) — out of scope.
make test green (+8 corpus rows, 0 new divergences), shakesmoke byte-identical.
The host/chez directory mixed jolt's own runtime (value model, seq, reader,
vars, ns, multimethods) with the shims that emulate the JVM: java.* / javax.*
classes, clojure.lang interfaces, and the host-class registry they hang off.
Move that JVM-emulation layer into host/chez/java/ so it reads as a distinct
unit instead of being interleaved with the platform runtime.
Moved (content unchanged): host-static, host-static-methods,
host-static-classes, host-class, dot-forms, records-interop, byte-buffer,
io, io-streams, inst-time, java-time, bigdec, natives-queue, natives-str,
natives-array, math, concurrency, async, ffi.
The load paths in rt.ss/cli.ss and the build.ss runtime manifest are updated
to point at java/; the build inliner follows the (load ...) strings, so the
AOT path needs no other change. All runtime shims, no seed source touched
(the three .clj edits are doc comments), so no re-mint.
Gate green: make test (selfhost fixpoint, certify 0-new, sci 211, infer),
shakesmoke (4 apps byte-identical).
