*in*, read-line, read, with-in-str, and line-seq land as a new overlay IO
tier (core/50-io.clj). *in* is a dynamic var holding a reader — a plain map
of two closures, :read-line-fn (next line, nil at EOF) and :read-fn (next
form, advancing past exactly that form). The default *in* reads real stdin
with a shared leftover buffer, so read and read-line interleave correctly;
with-in-str rebinds *in* to a string reader over one atom-held buffer —
(read) consumes its form, a following (read-line) returns the rest of that
line, as in Clojure. read has the 0/1/3 arities (EOF throws, or returns
eof-value when eof-error? is false).
The Janet seed grows two seams next to read-string: __stdin-read-line (one
line off stdin, newline stripped) and __parse-next (one form off a string ->
[form rest], nil at end of input) — and loses the line-seq stub.
Two traps hit and documented for future tiers: a map LITERAL with :jolt/type
as a key is read as a tagged form (don't tag overlay value maps), and a
leftover seed stub holding the same name breaks direct-linked self-recursion
— the overlay line-seq's recursive call bound to the stub's root, truncating
after one line. The stub's string-splitting behavior is kept as a documented
extension.
20 new io-spec rows (read-line EOF/interleave, read arities + eval round-trip,
line-seq incl. real-stdin paths). Gate green: conformance 326x3, suite 4577,
full jpm test.
* core: fix jolt-265 — syntax-quote fully-qualifies core syms to clojure.core/
Re-attempt of the deferred gap, now unblocked. The earlier uberscript break
wasn't qualification itself but an aliased-ref resolution bug it exposed:
resolve-var looked up ns-aliases (e.g. g/foo) against the analyzer's REBOUND
ctx-current-ns (jolt.analyzer, since the analyzer runs interpreted in its own
ns) instead of the namespace being compiled. A user's aliased refs failed
mid-compile (g/hello -> nil in the bundled standalone).
- resolve-var resolves aliases against :compile-ns when set (same ns
h-current-ns uses), falling back to ctx-current-ns — correct for both modes.
- sq-symbol qualifies a resolved clojure.core name to clojure.core/<name>
(Clojure hygiene); special forms stay bare; unresolved syms -> current ns.
Tests updated to the qualified behavior (features-test, reader-forms-spec).
* test: comprehensive spec — regex + sorted colls + random/predicate gaps
Filling the biggest untested clojure.core areas found in a coverage audit
(168 of 506 provided fns had no spec). New + expanded suites:
- regex-spec.janet (20): #"…" literals, regex?, re-find/re-matches/re-seq
(match/no-match/groups), re-pattern, and clojure.string split/replace with
regex (incl $1 backrefs). Whole area was previously unspecced.
- sorted-spec.janet (14): sorted-map/sorted-set construction + ordering, sorted?,
subseq/rsubseq. Pins the working subset — get/conj/assoc/keys/vals on sorted
colls and the by-comparator ctors are not yet first-class (jolt-ti9).
- predicates-spec +14: seqable?, integer?, reduced?/unreduced, not-empty.
- numbers-spec +5: rand/rand-int/rand-nth invariants.
Fix: sorted? was bound to core-sorted-map? so it returned false for sorted-sets;
now true for both sorted maps and sets (core-sorted?).
Filed: jolt-ti9 (sorted collections incomplete: get/conj/assoc/keys/vals don't
operate on the sorted wrapper; sorted-*-by ignore the comparator).
Gate green incl full jpm build + jpm test.
* core: close surfaced gaps — first-class sorted colls, with-out-str, rand arity, deref reduced
jolt-ti9: sorted-map/sorted-set are now first-class across the collection fns —
get/assoc/dissoc/conj/contains?/keys/vals/disj and call-as-fn all operate on the
wrapper and preserve sort order. The by-comparator constructors (sorted-map-by/
sorted-set-by) now thread the user comparator (numeric or boolean-predicate) through
all derived colls. Sorted predicates/ctors/ops moved above core-conj so the
collection fns can branch on them; jolt-invoke (interpreter) gets inline branches.
jolt-rfw: add with-out-str (binds output to a string buffer) + the macro.
jolt-ek3: (rand n) arity and deref-of-reduced (uuid? still deferred).
Specs: new io-spec.janet; sorted-spec expanded to pin the now-working map/set ops
and by-comparator ordering; predicate/number spec restorations.
* remove old doc
* core: fix stale comment — by-comparator sorted ctors are implemented
