Rename src/jolt -> stdlib (the runtime-loaded layer; jolt-core stays the
seed-baked layer) and update the loader / emit-image / doc paths. Drop dead
code: the spike/ experiments, the duplicate clojuredocs-export.edn (json moves
to tools/), the Janet-era jolt.http binding, and the orphaned
persistent_vector.clj whose ns/path didn't even match.
Strip porting residue from comments and docstrings across host/chez, jolt-core,
stdlib, tests, and docs: internal issue ids, "Phase N" markers, and the "vs
Janet" historical exposition, leaving present-tense descriptions and the real
JVM-Clojure semantic contrasts. Same pass over the corpus suite labels. The seed
is unchanged (docstrings/comments aren't emitted), so the self-host fixpoint and
corpus are untouched.
Port tools/spec_coverage.py off the dead janet probe to bin/joltc and regenerate
coverage.md; drop the dead :host/janet rule from certify.clj and regenerate the
conformance profile. Add docs/host-interop.md (the JVM shims and how to register
your own host class from a library) and a writing-style note in CLAUDE.md.
Stabilize the four racy concurrency corpus cases (future-cancel and agent
send/send-off): give the future a sleeping body and the agent a slow action, so
cancel reliably catches an in-flight future and deref reliably reads the
pre-update snapshot. They certify deterministically now, so drop their :flaky
allowlist entries and the orphaned legend.
Bring the docs in line with the actual implementation now that Chez is the sole
substrate.
Deleted the migration/spike/handoff artifacts that only documented the Janet
era or the port effort: the port plan, phase-0 and foundational-runtime spike
writeups (+ the stray root-level copy), the self-hosting design notes, the
architecture-refactor plan, and spike/chez/RESULTS.md.
Rewrote the current reference docs against the Chez facts: building-and-deps and
tools-deps (no jpm/build step — bin/joltc off the checked-in seed, deps via
jolt.deps into ~/.jolt/gitlibs), libraries (SQLite is built-in jdbc.core over
libsqlite3, not a Janet driver), the conformance/spec test-flow docs (the Chez
corpus runner + certify, no .janet harnesses), and the transient / type-hint /
seed-overlay design notes (Chez representations: mutable transients, flat
copy-on-write vectors, HAMT maps, the seed/overlay twin). Fixed the README
collections line (vectors aren't 32-way tries) and added the ffi/transient gate
targets. rfc 0001's numerics open-question is resolved (the Scheme tower).
Renamed the built-in HTTP adapter to jolt.http.server only (dropped the
ring-janet.adapter alias — a Janet-era name).
Running a program is a closed world — every namespace is required, then it runs
to completion — so make it direct-link by default (inlining, record shapes, the
inference's specialization), and for a -m/-M entry auto-enable the whole-program
cross-namespace inference pass. A decomposed multi-namespace program was ~3.7x
slower than the same code in one namespace purely because per-namespace
inference can't see a caller in a not-yet-loaded namespace; this closes that for
the common case with no flags and no hints.
Interactive modes (repl, -e, nrepl-server) stay indirect/open — they have to let
you redefine vars, which direct-linking seals against. Opt-outs:
JOLT_NO_DIRECT_LINK forces the open path even for a program run (hot-reload,
runtime redefinition); JOLT_NO_WHOLE_PROGRAM keeps direct-linking but per-ns;
JOLT_DIRECT_LINK / JOLT_WHOLE_PROGRAM still force-on. Namespaces required inside
-main (after the batch pass) fall back to per-ns inference.
The success checker (RFC 0006) rides on the inference for free, but a casual
program run shouldn't spam type warnings just because it now direct-links, so its
default-on is suppressed when direct-linking was auto-enabled (:direct-link-auto?);
an explicit JOLT_DIRECT_LINK or JOLT_TYPE_CHECK still turns it on. whole-program-
test and devirt-test opt their per-ns baseline out of the new auto-default.
Docs: RFC 0005 gains 'Compilation modes and defaults' + 'Cross-namespace
inference'; RFC 0004 documents cross-ns/param hints; self-hosting-compiler and
--help updated. Full gate green.
0005 proposes replacing the ad-hoc inference lattice with one recursive
structural type (a struct carries its field types, a vector its element type,
recursively), so a lookup returns its field's type and nested access is typed
end to end. It unifies :struct tracking with field tracking, subsumes the
current inference phases, and is the soft-typing (HM + a dynamic top) design:
structural types + core-fn type schemes, solved by lattice join with :any as
top instead of unify-or-fail. Includes the depth cap for termination and an
explicit design-problems section.
0006 (follow-up, depends on 0005) reuses the inference as a loose type checker
in the success-typing discipline (Dialyzer): report only PROVABLY-wrong code
(a concrete type in an operation's throwing error-domain), accept everything
ambiguous, never a false positive. Curated error-domain table, strictness
levels (off/warn/error), clear located messages, and the soundness boundaries
(closed-world, macros, unions).
