File API (jolt-hjw): io/file and (File. …) build a tagged :jolt/file value
(instance? File true) with a full method surface (isFile/isDirectory/exists/
getName/getPath/getAbsolutePath/listFiles/toPath/delete/createNewFile/…) backed
by os/ and file/. file-seq is File-aware (leaves are File values). str/slurp/spit
coerce :jolt/file to its path. ClassLoader/getSystemClassLoader + a classloader
stub whose getResource returns nil degrade migratus's classpath lookup to the
filesystem. java.nio.file Path/FileSystem/PathMatcher are shimmed just enough for
script-excluded?'s glob (recursive * / ? matcher).
Three bugs found getting migratus's migration discovery to work:
- (assoc nil k v) returned a raw janet table, not a map, so assoc-in built tables
that count/seq rejected. Now returns an immutable map.
- methods/get-method resolved the multimethod symbol at runtime in the current
ns, so a bare multifn ref in its defining ns saw an empty table once defmethods
lived elsewhere. Now they take the multimethod VALUE and recover the var via a
registry (Clojure semantics).
- defmulti now drops a leading docstring/attr-map (migratus's multimethods carry
docstrings) instead of treating the docstring as the dispatch fn.
Conformance 335/335 x3, clojure-test-suite at baseline.
