set was a native shim (apply jolt-hash-set (seq->list coll)). It is a
pure composition, so the Clojure version (apply hash-set (seq coll))
lowers to the same code. The compiler uses set, but only off the emit
path (the backend's bare-native-names def and type inference), so it can
live in the kernel tier: compiling that tier never calls set, and by the
time those callers run the tier is already bound.
This is distinct from boolean, which the backend calls for every :if
node on the emit path. Moving boolean even to the kernel tier deadlocks
(compiling the tier that defines boolean needs boolean), so boolean stays
native. Added a comment in predicates.ss recording that.
Re-mint converges in 3 passes and the benchmark suite is unchanged
within noise (collections 43.3 vs 43.1, binary-trees 367 vs 367, the
rest flat).
- == 1-arg returns true for any value (Clojure short-circuits before the number
check), not 'requires numbers'.
- current-time-ms wired to now-millis so the time macro works.
- subvec truncates float/ratio indices via long (Scheme quotient rejects flonums).
- defonce checks bound? not var-get — in a top-level do the name is already an
unbound interned cell, which var-get throws on.
- drop the line-seq corpus row (used janet/spit, N/A); allowlist char-array
(needs Class/forName "[C").
Corpus 2678->2683, floor raised. Re-minted. Full gate green; CI green.
jolt-cf1q.7
Rephrase comments that pointed at deleted Janet files (emit.janet, the seed
sources, 'the Janet back end punts ...') to present-tense descriptions of the
Chez behavior. Comment/docstring-only; the self-host fixpoint is unchanged
(comments don't affect the compiled seed).
Delete five files that were Janet-host shims with no Chez path: clojure.java.io
(provided natively by host/chez/io.ss), and jolt.{nrepl,png,interop,shell}
(the janet.* bridge, os/shell, janet.net — none exist on Chez).
jolt-cf1q.6
adds self-hosted compiler is functionally:
- The default compile path is the portable pipeline using jolt.analyzer (Clojure) → host-neutral IR → backend.janet.
- The analyzer is itself Clojure, compiled by jolt for true self-hosting.
- bootstrap-fixpoint passes (stage1 == stage2 == stage3): rebuilding the compiler on its own output.
- clojure.core is now self-hosted in the overlay.
- Stateful forms (defmacro/ns/deftype/defmulti/require/in-ns) are interpreted by design.
