JLLL v2.2.0

What's New in JLLL 2.2.0

Dynamic Classpath Support

Load Maven dependencies at runtime with environment-scoped classloaders:

;; Load external library and use it
(env :depends '("com.google.code.gson:gson:2.10.1")
  (define Gson (class "com.google.gson.Gson"))
  (define gson (new Gson))
  (invoke gson "toJson" '(1 2 3)))
;; => "[1,2,3]"

;; Create reusable environment with dependencies
(define json-env (env :depends '("com.google.code.gson:gson:2.10.1")))
(eval :env json-env '(new (class "com.google.gson.Gson")))

Features:

• Full transitive Maven dependency resolution
• Environment-scoped classloader isolation
• Custom repository support with :repos
• Introspection via (env-classpath)

See docs/dynamic-classpath.md for full documentation.

Console Abstraction

Unified styled I/O operations across CLI and REPL modes:

• New Console interface with PlainConsole and JLineConsole implementations
• Single *console* binding replaces *stdout*, *stdin*, *terminal*, *color-enabled*
• Semantic output methods: printHeader(), printError(), printWarning(), printSuccess()
• Colored output in REPL, plain text in scripts/tests

Breaking Changes

• *stdout*, *stdin* bindings removed - use *console* instead
• *terminal*, *color-enabled* bindings removed from REPL
