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
A typo'd symbol used to auto-intern an unbound var and die later as
'Cannot call nil as a function' with no hint which symbol. Now:
$ jolt -e '(undefined-fn 1)'
Error: Unable to resolve symbol: undefined-fn in this context
The analyzer's :unresolved fallthrough now punts to the interpreter
(whose resolver raises the message above when the form runs) instead of
emitting a var-ref that interned the var. A punt rather than a hard
throw because runtime-interning forms (defmulti's setup) legitimately
reference the var they're about to create from a nested do.
Pulling that thread surfaced three real bugs the leniency was masking:
- h-resolve-global resolved unqualified symbols against ctx-current-ns,
which during analysis is jolt.analyzer — so user-ns vars NEVER
resolved through it; the lenient arm happened to emit the right ns.
Now resolves against the compile ns like the qualified branch.
- Top-level (do ...) wasn't split: Clojure compiles and EVALS each
child in sequence so earlier children's runtime effects (defmulti's
intern) are visible while later children compile. eval-toplevel now
splits.
- The stdlib itself had forward references the auto-intern hid:
10-seq's transducers used vreset!/vswap! from 20-coll (moved to
10-seq); in 20-coll qualified-ident?/realized?/list*/underive
referenced defs declared later in the file (reordered); sorted? and
partition-all are genuinely later-tier and got (declare ...).
Test rows updated where they encoded the old leniency: ir-passes'
dead-branch row (unresolved in a dead branch is an error, as in
Clojure), compile-mode's ctx-isolation row (other ctx now errors
instead of reading nil), cli rows assert the new message. Gate green,
conformance 335/335 x3, suite 4718 steady, bench within noise.
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.
