joltc grew from a single -e expression into a real project runner. require now
loads a namespace's .clj/.cljc from the source roots transitively (load-once),
so a multi-file project works; the corpus/unit gates load compile-eval.ss but
not the loader, so their alias-only require is unchanged.
jolt.deps resolves a deps.edn into ordered source roots — git + local deps only
(no Maven), breadth-first so a top-level pin wins, with aliases (:extra-paths/
:extra-deps/:main-opts) and tasks. Git deps clone into a sha-immutable cache
($JOLT_GITLIBS, else ~/.jolt/gitlibs) by shelling out to git via a new
jolt.host/sh primitive. jolt.main dispatches run -m / -M:alias / -A / repl /
path / a deps.edn task. The launcher passes the user's cwd as JOLT_PWD (the
project dir) since it cd's to the repo root for the runtime's relative loads.
Remove the Janet seed (src/jolt/*.janet: reader, value layer, vars/ns, the
tree-walking interpreter, the Janet backend, the optimizing compiler), the
Janet->Scheme cross-compiler (host/chez/{driver,emit,jolt-chez}.janet),
bin/jolt-chez, the jpm build (project.janet) and the Janet test runner
(run-tests.janet), plus the entire Janet test suite. jolt now builds and runs
on Chez alone: bin/joltc off the checked-in seed, bootstrap.ss to rebuild it.
The portable Clojure stays: jolt-core/**, host/chez/**.ss, and the stdlib +
tooling under src/jolt/clojure + src/jolt/jolt (read by the seed build, no
Janet). The gate is 'make test' (self-host, corpus, unit, cli smoke, certify).
Drop the sci and clojure-test-suite submodules (used only by deleted Janet
integration tests); irregex stays.
Filesystem corpus/unit cases that probed project.janet now probe README.md.
jolt-cf1q.6
The runtime counterpart to bootstrap.ss. host/chez/cli.ss loads the checked-in
seed + the zero-Janet spine and compiles+evals a -e expression entirely on Chez;
bin/joltc execs it. With the seed checked in, a clone runs jolt with only Chez
installed — no Janet at build or run time. Multi-form -e wraps in (do ...) to
match Clojure. test/chez/cli-test.janet 9/9.
Emit every non-macro clojure.core form through the live analyzer -> Chez emit
pipeline as a def-var! prelude (prelude mode, tier dependency order), load it
before a user expression, and you get an -e-capable jolt-chez: analysis on Janet,
execution on Chez. driver/emit-core-prelude assembles it (each form behind a
silent load guard so the Phase-2 multimethod forms don't break the rest);
bin/jolt-chez is the -e CLI, caching the prelude on disk keyed by source hash.
run-corpus-prelude.janet is the full parity gate this opens, the prelude-backed
sibling of run-corpus-chez. First baseline: 1220/2497 evaluated cases pass, 0 new
divergences (10 allowlisted: dynamic vars, class names, eval-order — deferred
Phase 2). The rest is the punch-list: ~360 emit-fail (real host interop, out of
the analyzer subset) and ~900 runtime crashes, mostly core fns calling
host-coupled seed natives with no Chez shim yet (str/format/vec, transients).
Follow-ups jolt-t6cr/kl2l/q3w8/9ls5.
Two shims landed to get the prelude to load and run. atoms.ss: atom/deref/swap!/
reset! (+ the compare/vals kernel) — needed at load time for
global-hierarchy = (atom (make-hierarchy)). predicates.ss: the type predicates +
name/namespace/boolean the overlay assumes are seed natives, matching the seed's
strict semantics. post-prelude.ss re-asserts char?/atom? after the prelude: the
overlay implements those by reading :jolt/type, which is false for Chez-native
chars/atoms, so its def-var! would clobber the correct native versions.
Per-case Scheme files are PID-unique so a foreground -e never reads a half-written
file while the gate runs.
