- subs requires a string and validates 0<=start<=end<=count (no Janet from-end/clamping); negative/out-of-range/nil indices throw - assoc! on a transient vector bounds-checks the index (0..count) subs 11-fail -> 24/5 (5 remaining are byte-vs-codepoint Unicode, platform); assoc_bang 32/6 -> 35/3. clojure-test-suite pass 3889->3898. spec: string/subs-strictness (7), transient/assoc!-bounds (4). jpm test green.

# clojure-test-suite conformance: runs the external, cross-dialect
|
|
# clojure-test-suite (https://github.com/lread/clojure-test-suite, EPL) against
|
|
# Jolt and asserts the number of passing per-function test files stays at/above
|
|
# a baseline. Like the jank battery, this does NOT vendor the suite — it
|
|
# references ~/src/clojure-test-suite if present and SKIPS cleanly when absent.
|
|
#
|
|
# Each suite file is a `clojure.test` namespace (one per clojure.core/string
|
|
# function). A minimal clojure.test + portability shim (test/support/clojure_test.clj)
|
|
# lets Jolt load them; `when-var-exists` auto-skips fns Jolt doesn't implement.
|
|
#
|
|
# Files are run in a one-shot worker subprocess (test/integration/suite-worker.janet)
|
|
# under a wall-clock deadline. Some suite tests build infinite sequences
|
|
# (cycle/range/transducers-over-infinite) that Jolt's eager evaluator can't
|
|
# truncate and so HANG rather than fail; the deadline contains them — a timed-out
|
|
# file is reported as :timeout and contributes nothing, no manual skip-list needed.
