Three canonical-conformance fixes from the post-shrink batch:
- bit-and/bit-or/bit-xor/bit-and-not get Clojure's variadic arities as
20-coll shells folding the binary host ops (now __bit-* seams). 2-arg call
sites still compile to the native janet op via the backend's native-ops
table. The passes.clj constant-fold table now names the seams — the public
fns are overlay and don't exist when the compiler loads (this briefly broke
every compile-mode init).
- core-set? recognizes the :jolt/sorted-set representation (jolt-dpn):
(set? (sorted-set 1)) was false, and ifn? on sorted sets inherited the bug.
- (if) / (if test) / (if test then else extra) throw in both the analyzer
and the interpreter — spec 03-special-forms X1, now marked verified.
Suite 4704 -> 4706; bench and the greeter example benchmark are flat.
Loading these libs via require worked (load-ns-source interprets, macros
expand lazily) but the same code inlined by uberscript routes through
eval-toplevel and compiled, surfacing four gaps:
- a ^{:map} metadata def name reads as (def (with-meta name m) v); the
analyzer died extracting the name (config.core's defonce env). It now
throws uncompilable so the interpreter, which handles it, takes over.
- declare was a no-op, so a compiled forward reference to a declared
name that collides with a janet root binding bound to the host fn
(selmer.parser's (declare parse) compiled to janet's 1-arg parse).
declare now expands to no-init defs, the interpreter interns them,
and the analyzer routes no-init def to the interpreter.
- class? was missing (selmer.util's exception macro calls it at
expansion time). Always false, like ratio? — no Class objects here.
- require of an unlocatable namespace silently left an empty ns behind,
deferring the failure to an unresolved symbol far from the cause. It
now throws like Clojure's FileNotFoundException. Namespaces entered
in-session count as loaded (Clojure puts them in *loaded-libs*), and
the SCI bootstrap opts out via :lenient-require? since its
clj-targeted requires can't all exist on this host.
* test: adapt jank's form/reader tests into spec suites; fix case no-match
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
* core: fix 5 Clojure-conformance gaps surfaced by jank tests
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).
