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).
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.
adds self-hosted compiler is functionally:
- The default compile path is the portable pipeline using jolt.analyzer (Clojure) → host-neutral IR → backend.janet.
- The analyzer is itself Clojure, compiled by jolt for true self-hosting.
- bootstrap-fixpoint passes (stage1 == stage2 == stage3): rebuilding the compiler on its own output.
- clojure.core is now self-hosted in the overlay.
- Stateful forms (defmacro/ns/deftype/defmulti/require/in-ns) are interpreted by design.
- host-interop-spec: add an 'interop / janet bridge' suite — janet/<name> and
janet.<module>/<name> resolution, the value-representation boundary (a Jolt
vector crosses as a Janet table), explicit-only (unprefixed module not
exposed), and unknown-symbol errors.
- nrepl-test: assert a def's value renders as #'ns/name (pr-str loops on a
var's cyclic ns refs, so jolt.nrepl renders vars itself).
Final spec areas. Bugs caught and fixed:
- (def name docstring value) used the docstring as the value; now the 3-arg
docstring form binds the value and records :doc meta
- resolve was a nil stub; now a special form resolving a symbol to its var
(nil if unresolved). Added find-ns (non-creating lookup) and ns-name.
- in-ns didn't evaluate its arg, so (in-ns 'foo) failed; now evaluates it per
Clojure (the integration test's unquoted form updated to the quoted idiom)
- #(... %& ...) built %& as a positional param instead of a & rest param;
now emits (fn* [... & gen] ...) so %& captures the rest
Full public-API spec layer now in place. conformance 218/218, jpm test green.
