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).
