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.
Fixed arities now throw Clojure's ArityException shape — 'Wrong number of
args (N) passed to: name' — on any count mismatch; variadic arities on fewer
than their fixed params. The compiled path already enforced fixed arities via
janet's native fn check and multi-arity dispatch; this adds the check to the
interpreter's single-arity closures (the oracle was silently dropping extra
args and giving a raw tuple-index error for missing ones) and guards the
compiled single-variadic wrapper's minimum. Messages carry the fn name when
there is one. 16 spec rows; the update.cljc suite row flipped green (4703 ->
4704).
Enforcement exposed that seq-to-map-for-destructuring had drifted: the spec
row called the 1-arity fn with two args, and the body silently dropped a
trailing unpaired element. Replaced with the canonical Clojure 1.11 version
(even pairs build the map, a single trailing element passes through — so
(f {:b 2}) kwargs calls work — and an unpaired key throws).
Also: transients RFC notes tuple support from the seed-shrink rounds.
Round 6 of the seed shrink (the printer round, scoped by the perf wall). The
five wrappers move to 20-coll over two new host seams: __write (push a string
to *out*) and __pr-str1 (render one value readably). The renderer itself
stays in the seed — it's representation-coupled (pvec/phm/phs/sorted
internals) and shared with the hot str, and rendering through overlay calls
would pay the per-element call cost everywhere big values get printed.
print-method as a real multimethod is follow-up work.
The new spec rows caught a renderer bug: string bodies were never escaped, so
(pr-str "a\"b") didn't round-trip through the reader. pr-render now
escapes quote/backslash/control chars per Clojure.
Round 5 of the seed shrink. transduce is the canonical 5-liner over reduce
(which already honors reduced and steps lazy seqs); eduction composes with
comp and stays eager into a vector (documented divergence, as before);
td-comp — eduction's last caller — is deleted from the seed. transient
accepts tuples now (reader vectors / map entries), so (into [] (first {:a 1}))
keeps working everywhere a vector does.
into was moved, benched, and moved back: the overlay call layers cost the
into-vec suite ~11% back-to-back (536 vs 480ms), the same per-call wall that
sent even?/odd? home in round 4. A transient conj! fast path didn't pay for
itself either (jolt call overhead dominates, not the per-element conj). The
seed keeps core-into + its private transduce machinery; the binding count
still drops by three.
Round 4 of the seed shrink. zero?, pos?, every? move to the syntax tier
(empty? and the analyzer use them — raw def+fn* per the file constraint);
char? joins the tagged-value predicates in 20-coll. coll? stays seed: host
set? doesn't cover sorted sets (filed jolt-dpn) and the tag check from the
overlay would hit the sorted-coll get trap. pos? guards number? explicitly —
the staged recompile emits bare > as the native janet op, which orders
strings (zero? gets the same guard; spec rows lock both plus neg?).
The canonical every? seq-walks its coll, which exposed that rest/next over
sets, phms, struct maps and sorted colls fell into core-rest's indexed
fall-through and walked the wrapper table's INTERNAL fields — (next #{1 2})
was (nil nil), (clojure.set/subset?) broke. core-rest now seqs those
representations (branches placed AFTER the hot vector/lazy paths; the first
ordering cost seq-pipe 4x). Suite rises 4700 -> 4703; baseline 4660 -> 4695.
even?/odd? are back in the seed after the bench A/B: (filter even? ...) pays
an extra call layer per element through the overlay (seq-pipe 262 -> 1100ms).
They join the perf-wall list with the lazy hot fns.
Round 3 of the seed shrink. To the overlay: identity, constantly, neg?,
even?, odd? (20-coll, ahead of their first in-tier uses), not= and unreduced
(00-syntax — the kernel and seq tiers use them), ==, ensure-reduced,
halt-when, parse-boolean, parse-uuid, newline, seque, array-seq, to-array-2d,
and the masking unchecked-byte/short/char/float/double coercions. parse-uuid
validates via re-matches over a new __make-uuid host binding (overlay source
can't write :jolt/type map literals). memfn moves to 30-macros as a working
macro over the .method call sugar instead of a fn that throws.
Behavior fixes toward Clojure, each with spec rows: == now throws on
non-numbers instead of comparing them, and halt-when is the canonical
::halt-map version (the halt value replaces the whole reduction result, no
double completion). list? and map-entry? stay in the seed — both are
representation-coupled (plist/tuple checks).
clojure-test-suite goes 4701 -> 4700: update.cljc expects
(update {:k 1} :k identity 1 2 3 4) to throw an arity error, and jolt fns
don't enforce fixed arity anywhere (pre-existing, language-wide — the seed's
Janet identity threw natively). Filed as jolt-6xn; fixing it should flip
several suite rows at once.
Jolt numbers don't overflow, so +'/-'/*'/inc'/dec' and the whole unchecked-*
family are just the checked ops — now one-line defs in core/20-coll.clj
instead of ~25 seed bindings. int? and num move the same way.
unchecked-divide-int now goes through quot, so dividing by zero throws like
the JVM instead of silently truncating infinity. unchecked-int/long gain
char handling via int, matching Clojure ((unchecked-int \a) => 97). The
masking byte/short/char coercions are not aliases and stay in the seed for
a later round.
Also drops a second duplicate set of unchecked defns that was shadowing the
first at module load.
The seed copies of inst?/inst-ms and the multimethod table ops
(get-method/methods/remove-method/remove-all-methods/prefer-method) are dead
code — the overlay redefines all of them (20-coll.clj, 30-macros.clj) — so
they're deleted along with duplicate bindings-table entries (unreduced,
eduction, unchecked-inc/dec/add/subtract).
New spec rows for methods/remove-all-methods caught two real bugs in the
evaluator's setup fns: methods-setup returned the live host table (count
rejected it, and callers could mutate dispatch state), and
remove-all-methods-setup swapped in a fresh table the dispatch closure never
saw. methods now returns a phm snapshot; remove-all-methods clears in place.
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.
The cache key was built with janet's (hash ...), which is seeded per
process, so it never matched across invocations and every jolt-deps run
re-resolved and re-fetched. Store the raw key material instead.
Run the jpm git calls silenced (:silent) with a one-line progress note
on stderr — the checkout chatter ("HEAD is now at ...") was landing on
stdout and corrupting the documented JOLT_PATH=$(jolt-deps path) capture.
Covered by two new deps-resolve checks: a cross-process cache-hit probe
(sentinel-tampered cache file) and a stdout-cleanliness check against a
local file:// git dep.
yogthos/config now loads and runs end to end: config.edn/.lein-env
deep merge, env vars keywordized and type-converted, PushbackReader
over io/reader, reload-env via alter-var-root. New shims:
java.io.PushbackReader (read/unread), Long/parseLong, BigInteger.,
Boolean/parseBoolean, System/getProperties; clojure.edn/read now
drains an actual reader (it used to read one LINE from a raw janet
file handle, so multi-line config files and shim readers both broke).
Three real bugs shaken out, each with regression specs:
- An empty rest arg bound () instead of nil. ((fn [& r] (if r 1 2)))
returned 1; the truthy () sent config's (or (.exists f) required)
down the wrong branch. Fixed in the interpreter and the compiled-fn
emission. Internal apply boundaries (protocol dispatch, core-apply)
now accept a nil seq like Clojure's (apply f x nil).
- seq/map over a raw janet table (System/getenv, os/environ) yielded
nothing, so config's read-system-env came back empty. Raw host
tables now seq as kv entries like any map, in core-seq,
realize-for-iteration, and coll->cells. The old spec row hid this
behind a vacuous (every? pred empty) — replaced with one that
asserts non-emptiness.
- edn/read single-line limitation, as above.
test/integration/config-lib-test.janet runs the real library from
~/src/config (skips when absent).
Git clones now default to a shared, sha-immutable cache —
$JOLT_GITLIBS, else <config-dir>/gitlibs — instead of a per-project
./jpm_tree, the tools.gitlibs ~/.gitlibs model. Passing tree
explicitly still works (tests do). The resolved-roots cache moves
out of the clone tree to the project-local .cpcache/jolt-deps.jdn,
since roots depend on the project while clones don't.
deps.edn grows :tasks, the honest subset of babashka's: a string
task is a shell command, a map task is {:main-opts [...] :doc}.
jolt-deps tasks lists them (merged user+project), jolt-deps task
NAME runs one. Bare-expression tasks are out of scope: the reader
hands back parsed data and round-tripping to source is fragile.
Also fixes load-config skipping the symbol-key normalization when
only one config file existed — :tasks/:deps keys stayed raw reader
symbols (which embed positions and never compare equal), so lookups
missed. Regression rows in deps-tasks-test; docs updated for the
whole tools.deps surface (aliases, -A/-M, user config, conflicts,
gitlibs cache, tasks).
deps.edn :aliases now work the tools.deps way, scoped to what jolt
supports (git/:local, no maven): :extra-paths and :extra-deps
accumulate across selected aliases, :main-opts is last-wins. The CLI
grows -A:dev:test (selects aliases for path/run/repl/-e) and
-M:alias (runs the alias :main-opts through jolt). A user-level
deps.edn ($JOLT_CONFIG, else $XDG_CONFIG_HOME/jolt, else ~/.jolt)
merges under the project file: :deps and :aliases merge per key with
the project winning, everything else replaces.
Resolution is now breadth-first so a top-level coordinate always
beats a transitive one for the same lib (it was DFS first-wins —
a dep's pin could shadow the project's own). Conflicting coordinates
for one lib warn on stderr with both coords and which won. Also
fixes dedup keying: it hashed the symbol struct's string repr, which
carries reader position metadata, so the same lib from two files
never deduped.
resolve-deps-cached keys on project edn + user edn + aliases.
Tests: deps-aliases-test and deps-conflicts-test, local deps only.
Selmer now loads and renders templates on jolt: variables, filters
(upper, date with JVM patterns), if/for tags, nested lookups, HTML
escaping, and render-file with its last-modified template cache.
New src/jolt/javatime.janet provides the java.time surface Selmer's
date filters use (DateTimeFormatter/Instant/ZoneId/LocalDateTime/
FormatStyle/Locale, epoch-ms backed, host-local timezone) plus the
java.io/java.lang/java.net shims its template reader needs
(StringReader, StringBuilder, URL, File/separator, Class/forName).
Everything registers through three new evaluator registries
(class-statics, tagged-methods, class-ctors), so the module is data
plus an install call.
Fixes shaken out along the way, each load-bearing for Selmer and
correct on their own:
- :refer :all silently referred nothing (it iterated the :all keyword)
- ns :import ignored vector specs and didn't share deftype ctor vars
- dot calls on deftype/reify instances never consulted the protocol
registry, so (.render-node node ctx) failed where (render-node ...)
worked
- instance? rejected expression type args like (Class/forName "[C")
- char-array didn't accept a string
- io/resource now searches the loader's source roots (the classpath
analog); io/reader handles char arrays, URLs, readers, and returns
an in-memory reader with :read-line-fn for file paths
- String .split (regex, JVM trailing-empty semantics), file-path
methods (.toURI/.toURL/.getPath/.lastModified/.exists)
- System/getProperty (os.name & co), the janet/* bridge now works
inside env-less fibers, and qualified class names that syntax-quote
mangles (selmer.util/StringBuilder) fall back to the ctor registry
Spec rows cover the shim surface; test/integration/selmer-test.janet
runs the real Selmer from ~/src/selmer (skips cleanly when absent).
\p{L}/\p{Lu}/\p{Ll}/\p{N}/\p{Z}/\p{Ps}/\p{Pe} (+\P negation) land in
both escape positions of the regex compiler, mapped onto the byte PEGs:
ASCII exact, any high byte (inside a UTF-8 sequence) counts as a LETTER —
so ^\p{L}+$ accepts UTF-8 words while \p{N}/\p{Z} stay ASCII. (?u) was
already a tolerated no-op flag. Unknown property names error at compile.
Chasing the acceptance target (cuerdas via deps-conformance) pulled in the
rest of its clj-compat chain, each a real gap:
- the deps-conformance harness reads libraries under clj-compat reader
features (deps are clj/cljc by definition — without :clj, cuerdas's
#?(:clj (instance? Pattern x)) branches resolved to NIL bodies)
- instance? knows Pattern/java.util.regex.Pattern (regex values) and
Character (cuerdas's rx/regexp? gate on split)
- the java.lang.String method surface: .toLowerCase/.toUpperCase/.trim/
.indexOf(-1 on miss)/.lastIndexOf/.substring/.charAt/.startsWith/
.endsWith/.contains/.replace/.equalsIgnoreCase/... — ASCII case mapping,
unknown methods error (the old path silently returned nil)
- the (.method obj args) SUGAR now desugars to (. obj method args) in the
interpreter — it was never implemented (bare .method heads resolved as
vars, hence 'Cannot call nil')
- Long/MAX_VALUE / MIN_VALUE statics (f64 approximations)
deps-conformance: medley ok, cuerdas ok (was check-error); dependency now
loads its clj branches and fails only on its single-segment ns resolution.
30 new spec rows (11 regex, 19 interop). Gate exit 0.
ifn? (jolt-1vx) is the canonical IFn set in the overlay: fns, keywords,
symbols, maps (sorted included), sets, vectors, and vars — NOT lists. The
seed version said true for lists and false for struct maps and vars.
Mutable-mode caveat documented (vectors and lists share the array repr
there). 13 predicate rows.
Multimethod dispatch (jolt-heo) now collects EVERY isa-matching method key
and picks the dominant one — x dominates y when prefer-method'd over it or
(isa? x y) — and two matches with no dominant is an ambiguity ERROR, as in
Clojure. It used to take whichever key the table yielded first, silently
ignoring prefer-method. The prefers store upgrades to Clojure's
{x -> set-of-dominated} shape, shared between the dispatch closure and
prefer-method-setup via the var; prefers becomes a macro over a setup fn
(the store lives on the VAR — the multifn value can't carry it, so the old
fn read {} forever). 6 multimethod rows + the conformance row updated to
the canonical shape (335x3).
The reader (jolt-ou8) kept the pending KEY when a comment or #_ sits in a
map's VALUE slot: the old code dropped both, desyncing kv pairing — the
real value became the next key and the closing brace landed in value
position ('Unmatched closing brace'). Selmer's deps.edn (a '; for
development (REPL, etc)' comment between key and value) now parses; 6
reader rows incl. nested commented maps.
Gate: jpm exit 0, conformance 335x3, all tests passed.
jolt.passes is the new portable pipeline stage between the analyzer and the
back end: pure IR -> IR rewrites, total over node :ops (unknown ops pass
through with folded children), loaded with the compiler namespaces and
resolved lazily by analyze-form (JOLT_NO_IR_PASSES=1 disables — the same
escape-hatch pattern as the macro oracle). The shape is flatiron's opt.clj
applied to the jolt IR, which is what jolt-2om asked for.
The first pass is constant folding: a call of a foldable numeric SEED fn
(the later tiers don't exist when the compiler loads) whose args are all
constant numbers becomes a constant, and an if with a constant test becomes
the taken branch (dead-branch elimination — the untaken side never even
resolves). Folding computes with the ACTUAL jolt fns, so results match
runtime semantics by construction; a fold that would throw (mod 5 0) is
left for runtime.
Two walk lessons paid for in debugging: let/loop bindings are
[name init-ir] PAIRS, not maps (assoc'ing :init into a pair corrupts it);
and a throw inside the interpreted pass unwinds past the interpreter's ns
restores, so analyze-form restores the compile ns after the (protected)
pass call — without that, one pass error left current-ns in jolt.passes and
the rest of the tier compile resolved against the wrong namespace (sort-by
landed on the 2-arg JANET builtin).
ir-passes-test pins folds, conservatism (free vars, throwing folds), and
end-to-end eval. Gate exit 0.
Every walk over a lazy seq created FRESH wrapper tables around the shared
rest-thunks (ls-rest, ls-seq/ls-count, realize-for-iteration, the printers,
reduce — each had its own make-lazy-seq loop), so independent walks re-ran
the thunks: side effects duplicated, and a doall'd seq of futures was
re-spawned serially by the deref walk. Every walker now goes through
ls-rest-cached, which memoizes the rest wrapper on its node — thunks run
exactly once, as in Clojure. Costs ~10% on walk-heavy benches (the per-node
cache get/put — Clojure's LazySeq pays the same); net still -9% vs the
pre-linear-walks baseline. Three regression rows pin once-only effects and
value stability across walks.
On top of that: pmap/pcalls/pvalues (jolt-oeu) over the real-thread futures
— spawn-all-then-deref (the once-only fix is what makes the doall actually
mean that), snapshot semantics documented, multi-coll arity via the
canonical vector-zip. System/currentTimeMillis + nanoTime land as System
statics (the realtime clock — os/time is whole seconds, which quantized
every elapsed measurement to 1000ms). Seven pmap rows incl. a generous-
margin parallelism check (4 x 200ms sleeps under 700ms after warmup).
The native-ops table grows from 9 to 16, each verified for semantic parity
with the jolt fn before inclusion (incl. negative operands): mod is floored
on both sides, rem (janet %) truncates, / is variadic with (/ x) -> 1/x.
quot is deliberately absent — janet div floors where Clojure truncates.
jolt's bit fns are 2-arg (unlike Clojure's variadic), so the bit ops emit
native only at exactly that arity; bit-not is unary. Eight new conformance
rows pin compile=interpret on the new ops at their guarded arities (334x3).
map-read 10.8 -> 9.2 ms (the (mod i 100) in its loop inlines). From the
flatiron review's unchecked-primitive-loops idea.
Reviewing flatiron's morsel batching for applicability turned up something
better hiding under the lazy machinery: every cell over a concrete
collection was produced by slicing the REMAINDER ((tuple/slice c 1) per
element in coll->cells, and rest/next sliced the same way), so any full walk
was O(n^2). mapv over 40k elements took 10.4 SECONDS; a 20k-element
first/rest loop took two.
Cells over indexed collections now walk by INDEX (one shared indexed-cells
helper, O(1) per step), and rest/next of a vector/tuple/list return an O(1)
lazy view from index 1 — which also makes (rest [1 2 3]) a SEQ, as in
Clojure (it was a vector-typed slice; seq?/vector? rows pin the change).
mapv 40k: 10405 -> 182 ms. rest-loop 20k: 2040 -> 31 ms. Whole bench:
seq-pipe -28%, into-vec -24%, str-join -18%, hof -26%, TOTAL 4565 -> 3753
(-18% vs main, back to back). Chunked seqs (jolt-yqc) drop in priority:
the quadratic walks were the actual cost; chunking now only amortizes
per-element closure allocation.
Nine regression rows incl. 20k/50k linear-scaling smoke tests. Gate exit 0.
require-:as wrote the string-keyed :imports table (which resolution reads)
while ns-aliases read the symbol-keyed :aliases table (which nothing wrote)
— so (ns-aliases) was always empty and the alias fn had to write both as a
bridge. :aliases (alias-name string -> ns-name string) is THE store now:
require :as and the alias fn write it, both resolution paths read it first
(falling back to :imports for class imports, which is all that table holds
now), ns-unalias removes one entry, and ns-aliases presents Clojure's
{alias-symbol -> namespace object} shape built from it. ns-resolve's
qualified path goes through the same lookup.
Also: the coverage dashboard's last 'resolvable-not-interned' entry was '.'
— which (resolve '.) returns nil for on the JVM too; the tool now classifies
it as the special form it is, and that category reads ZERO.
7 new unified-alias spec rows (require/alias/ns-unalias round-trips through
both the resolution and introspection views); the white-box namespace test
tracks the accessor rename. Gate exit 0.
(recur (inc acc) (rest xs)) re-entered the fn through its varargs collector,
so the rest seq came back wrapped in a fresh 1-element rest list — xs never
emptied and the interpreter hung (jolt-4df; the compile path was already
correct). recur now re-enters through a dedicated entry that binds the LAST
arg directly as the rest param (n-fixed + 1 args, Clojure's contract), in
both the single-arity and multi-arity fn* paths; the shared body runner keeps
the ns-swap/restore in one place, and fixed arities still re-dispatch through
the arity dispatcher exactly as before.
Six spec rows: the original repro, zero-fixed variadic, rest-empties-to-nil,
multi-arity variadic recur, nil rest, and a fixed-arity control.
clojure.edn was nearly complete (sets, #uuid/#inst, :eof all landed earlier);
the :readers opt was ignored and :default missing. Both work now — the
reader stores a tag as a :#name keyword, so the lookup normalizes it to the
symbol Clojure keys :readers with; :default gets (tag value); built-in data
readers stay the fallback. 8 new edn spec rows. This was the last open item
of jolt-0mb (the vendored walk/zip/data/edn battery has been green for a
while: 34/33/61/50, all clean).
Chasing the probe cascade ('Unable to resolve symbol: edn/...' after one
error) found a real evaluator bug: an interpreted fn body runs with
current-ns rebound to its DEFINING ns and restores it with a plain trailing
call — an UNCAUGHT throw skips every restore on the way out, leaving the ctx
stuck in the deepest callee's ns, where alias-qualified lookups then fail
(the same cascade previously seen via sci). The repair lives at the
TOP-LEVEL boundary (loader/eval-toplevel saves the entry ns and restores it
on error before re-raising) — NOT per-call defer/try, which builds a fiber
per frame and blew the C stack on deep interpreted recursion (file-seq)
when tried first. Regression tests cover the cross-eval leak and that
aliases keep resolving.
test/spec/untested-vars-spec.janet adds 143 rows asserting jolt's documented
behavior for the whole implemented-untested category — primed arithmetic,
the array/aset/coercion stubs, unchecked-*, the chunk family, JVM-shape
stubs (class/bean/proxy/memfn as resolve-only or :throws), ns/REPL
machinery, and the misc seqs. tools/spec_coverage.py now checks each var as
a whole TOKEN in the test sources (call-position-only matching missed *1,
+', ., .., /, and bare transducer refs like cat).
Writing rows from probed truth surfaced five real bugs, all fixed:
- comp with a jolt-IFn stage silently returned nil ((comp seq :content)) —
raw Janet keyword application is not jolt invoke. comp is the canonical
overlay defn now (fixed-arity composed fn, so the hot 1-arg path is two
direct calls); the seed keeps a private td-comp only for the transducer
machinery. hof bench +9% vs native, the price of correct IFn dispatch.
- extend (the fn) was a nil-expanding stub MACRO shadowing any definition;
it's a real fn over register-method now, and extends? (a constant-false
stub) is real over extenders
- (.. x f g) hit the 'ClassName.' constructor branch (a name ending in a
dot) and died; .. is the canonical threading macro now
- aclone errored on pvecs; ns-interns/ns-imports returned live host tables
that count/seq reject (now structs)
Thread/sleep + Thread/yield land as Thread statics beside Math/: sleep parks
the WORKER's own event loop (each future thread has one), which makes timed
deref provably fire — futures-spec gains the timeout-fires, sleep-in-body,
and timed-out-future-still-completes rows. The futures impl itself already
ran on real OS threads (ev/spawn-thread + marshalled results); jolt-ejx was
stale.
Dashboard: implemented+tested 433 -> 564 of 694; implemented-untested and
missing-portable are both EMPTY. Gate: jpm exit 0, all tests passed.
The dashboard's missing-portable category is now EMPTY (was 35 when the issue
was filed; this session's io/leaf work had already landed most of them).
The final seven:
- extenders — ctx-capturing clojure.core fn over the protocol type-registry:
the type-tags implementing a protocol, as symbols; nil when none
- find-keyword — keyword: jolt keywords have no intern table, so it always
finds (babashka makes the same call)
- inst-ms* — the raw Inst method; one inst representation, so = inst-ms
- read+string — over the 50-io readers, which now expose :buf and :fill-fn;
returns [form exact-text-consumed], EOF throws or yields [eof-value ""]
with the 3-arity, works for string AND stdin readers
- with-local-vars — fresh free-standing var cells (__local-var seam) bound as
locals; var-get/var-set work on any cell
- with-open — canonical recursive expansion closing through the __close seam:
a map-like value's :close fn or a host file (no .close interop here);
nested closes run inner-first, finally runs on throw
- with-precision — body evaluates with precision/:rounding accepted and
ignored (doubles, no BigDecimal context) — documented divergence
30 new spec rows (test/spec/missing-vars-spec.janet); coverage.md
regenerated: implemented+tested 426 -> 433, missing-portable 7 -> 0.
Gate: jpm exit 0, all tests passed.
