Stage 1 jolt-g3h. set? and disj were special-cased in all three "can't compile"
lists (host_iface special-names, compiler.janet uncompilable-heads, evaluator
special-symbol? + handlers) — but they're pure value-production with callable
core vars (core-set?/core-disj), and those vars are byte-for-byte equivalent to
the evaluator handlers. Removed them from all three lists + dropped the now-dead
evaluator handler arms, so they're ordinary clojure.core fns everywhere: the
analyzer compiles (set? x)/(disj s x) as normal var calls instead of punting to
the interpreter.
Verified identical results in default AND JOLT_MUTABLE builds (no representation
sensitivity — sets are phs in both, unlike vector?/list? which collapse).
With this, the self-hosted analyzer's compile-path fallback set equals the frozen
intentional stateful set (Task 2) — it's now a strict superset of the bootstrap
compiler's compilable surface, so the Janet bootstrap is retireable (Stage 2).
fallback-zero: set?/disj moved to must-compile (31 now), set! into must-punt.
Gate: conformance 267x3 (+5 set?/disj cases), lazy-infinite 44/44, suite 4034/67,
fixpoint, self-host, sci, specs+unit green.
Stage 1 Task 1. analyzer.clj punted set literals to the interpreter
((form-set? form) (uncompilable "set literal")); now it builds the set-node IR
(already defined in ir.clj) from (form-set-items form), and backend.janet emits
(make-phs e1 e2 …) — each element evaluated then the persistent set built,
mirroring compiler.janet's emit-set-expr and the interpreter's :jolt/set path.
Closes a self-hosted-analyzer vs bootstrap-compiler parity gap: #{…} no longer
forces interpreter fallback on the compile path.
Gate: conformance 262x3 (+4 set-literal cases incl computed elements / empty /
in-let), fixpoint, self-host, sci, suite 3981/66, specs+unit green; core-bench
neutral (A/B). set?/disj-as-fns remain deliberately interpreted (in-sync across
all three lists) — adjudicated in Task 2.
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.
- A map entry is a 2-element tuple (Jolt produces tuples only from map iteration;
vector literals are pvecs, lists are arrays). key/val/map-entry? now accept a
2-tuple and reject a plain vector, matching Clojure's MapEntry-vs-vector
distinction — no metadata needed, the representations already differ.
- min-key/max-key reproduce Clojure's NaN-aware folding (2-arg strict </>, then
<=/>=) and require numeric keys (NaN allowed, strings throw).
- subvec coerces float/NaN indices like (int ...) (truncate, NaN->0) then
bounds-checks, instead of throwing on non-integers.
min_key 35/14 -> 49/0 (clean); key/val recover the 2-vector cases; subvec floats
fixed. clojure-test-suite pass 3898->3921. Updated conformance-test (key/val now
needs a real entry). spec: map/map-entry-&-key-ordering (14). jpm test green.
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.
