All from adapting jank's form/reader tests; each fix verified in interpret +
compile modes and the spec tests now assert the correct behavior.
- jolt-vdo: case now rejects duplicate test constants at expansion (Clojure
compile error), via bootstrap-safe duplicate detection (00-syntax; analyzer.clj
uses case during its own build, so seed-only fns).
- jolt-w2v: loop bindings are now sequential like let — a later init can
reference an earlier binding. Fixed the interpreter loop* (accumulating scope)
and the back end emit-loop (bind initial inits in a sequential Janet let before
entering the recur target).
- jolt-6x1: #() reader computes the fixed arity from the MAX positional (%2 ->
[p1 p2 & rest]); % and %1 unify; unused lower slots get placeholder params.
- jolt-xl0: ^meta on collection literals ({}/[]/#{}) now attaches — read-meta
passes the NORMALIZED metadata map to with-meta (was the raw meta-form).
- jolt-edb: syntax-quote processes ~/~@ inside set literals (new __sqset builder
in core + set branches in syntax-quote* and syntax-quote-lower).
Deferred: jolt-265 (fully-qualify core syms to clojure.core/ in syntax-quote) —
it passes conformance but breaks the standalone uberscript (the ns macro emits
unqualified require/in-ns, which then qualify and break bundled require/alias).
Reverted to bare (functionally resolves); re-opened with the finding.
Gate green incl full jpm build + jpm test: conformance 269x3, suite >=4034/67,
fixpoint, self-host, sci 422/0, uberscript, all unit + spec (forms 55, reader 31).
Vendoring jank's behavior (not the project): we base our own copies on the
jank test corpus to close coverage gaps, but maintain them ourselves since
jank may diverge. Two new spec batteries (jank-isms translated to Jolt:
letfn* -> letfn, jank catch types -> :default; platform-specific bigdec/
biginteger/ratio/uuid/##Inf/unicode cases omitted):
- test/spec/forms-spec.janet (52): case, fn (arity/variadic/closure/recur/
named), let, letfn, loop, try, if/do/def/call — incl :throws regression
cases (no-match, bad params, nil call).
- test/spec/reader-forms-spec.janet (22): #() (% %N %&), #' var-quote,
^metadata, syntax-quote (gensym/unquote/splice).
Fix surfaced by adaptation: case with no matching clause and no default now
throws 'No matching clause' (Clojure semantics) instead of returning nil
(00-syntax). Gate green incl full jpm build+test.
Other gaps the adaptation surfaced are filed (tests adjusted to jolt's
current behavior + a comment, not silently dropped):
jolt-vdo case duplicate test constants not rejected
jolt-w2v loop bindings not sequential (later init can't see earlier)
jolt-6x1 #() %& miscomputes arity with a higher positional (%2 …)
jolt-xl0 ^meta not attached to collection literals ({}/[]/#{})
jolt-265 syntax-quote doesn't fully-qualify core syms to clojure.core/
jolt-edb syntax-quote ~/~@ not processed inside set literals
