(chan n xform) applies a transducer on the put side: a jolt transducer is a
directly-callable closure, composed over a reducing fn whose step gives each
output value into the channel (honoring its buffer kind). One put may yield zero
or more values; a reduced result (e.g. from take) closes the channel; close!
runs the transducer completion arity to flush stateful remainders. Works with
map/filter/mapcat/take/comp/etc.
Buffers: (buffer n) fixed, (dropping-buffer n) drops new values when full,
(sliding-buffer n) drops the oldest. Implemented via a non-blocking give —
(ev/select [ch v] closed-chan) detects a full buffer without parking.
harness: run-spec flushes per suite. spec: core.async/channel-transducers (5),
core.async/buffers (3). jpm test green.
Note: distinct/dedupe/partition-all/partition-by still lack a 0-coll transducer
arity in core (separate gap), so they can't yet be used as channel xforms.
Reorganize the flat 49-file test/ into three layers (jpm test recurses, so all
are still discovered):
- test/unit/ white-box component tests (reader, evaluator, types,
persistent-map, lazy-seq, macro, interop, compiler)
- test/integration/ cross-cutting + regression batteries (conformance, jank,
sci-bootstrap/runtime, features, systematic-coverage, api,
core, namespaces, ported clojure suites) and
.../ports/ ported clojure/cljs test batches pending consolidation
- test/spec/ the behavioral contract (built out in following commits)
- test/support/harness.janet shared defspec table runner (cases compared via
Jolt's own =, with a :throws sentinel) + expect= helpers
Files moved with git mv (history preserved) and import paths fixed for depth.
jpm test green. README Test section updated.
Next: build out test/spec/ to cover the public API area-by-area, mining the
integration batteries and filling gaps.
