Both printers (jolt-pr-str, jolt-pr-readable) now thread a print depth and
read the two limit vars. *print-length* truncates each collection to N
elements + "...", walking seqs lazily so an infinite seq prints under the
limit without realizing it. *print-level* renders a collection at depth >=
the level as "#". The reader consults *default-data-reader-fn* for an
unregistered #tag before falling back (tagged form on the data seam, throw
on the edn seam). All three interned with nil defaults.
Spec coverage dashboard had 6 missing-portable and 24 dynamic-var entries. The
portable ones are now implemented (missing-portable -> 0, dynamic-var -> 14):
- Stateful matcher: re-matcher now returns a real mutable Matcher; re-find over
it steps through matches and re-groups returns the last match's groups (was an
inert tagged map). Closes re-groups.
- letfn is interned as a clojure.core var so (resolve 'letfn) matches the JVM. It
stays a special form (the value is never invoked, not marked a macro).
- *1 *2 *3 *e interned (nil outside a REPL).
- Portable dynamic vars whose default already matches jolt's behaviour:
*read-eval* *print-dup* *print-namespace-maps* *flush-on-newline*
*compile-files* *math-context* *command-line-args* *file*.
The remaining 14 dynamic-var entries are host-internal (compile-path,
compiler-options, fn-loader, reader-resolver, repl, source-path, ...) or deferred
pending printer/reader support (*print-length* *print-level*
*default-data-reader-fn*). Corpus rows added for each closed gap; coverage.md
regenerated.
clojure.core/*print-meta* was missing, so (binding [*print-meta* true] …) failed
to compile ("var of non-var"). Add it (default false, like the JVM); corpus
covers binding it.
Two small clarity moves from the review:
- dynamic-vars.ss -> dynamic-var-defaults.ss. It holds the default VALUES of a few
core dynamic vars (*clojure-version*, *assert*, …); the near-identical dyn-binding.ss
holds the binding-stack machinery. The names were easy to confuse.
- Pull the ~60-line %-format engine out of the natives-misc.ss grab-bag into
natives-format.ss (its ->long/pad-left/fmt-float helpers were local to it).
rt.ss loads + MODULES.md updated. Runtime .ss, no re-mint; make test green, format +
the dynamic vars verified.
