Rouge

Ruby + Clojure = Rouge.

Why?

Clojure is elegant and fun.
Quick boot time (currently around 0.1s).
Ruby's gems tend to be modern with decent APIs.

You can try a Rouge REPL online at Try Rouge, or install the gem to get the local REPL:

gem install rouge-lang
rouge

You'll see the user=> prompt. Enjoy!

You can discuss on Google Groups' rouge-talk, or on #rouge on Freenode.

example

See boot.rg, em-rg, mechanize-rg, but to demonstrate salient features:

; define a macro
(defmacro defn [name args & body]
  `(def ~name (fn ~name ~args ~@body)))

; call a Ruby method on Kernel (if the ruby namespace is referred)
(defn require [lib]
  (.require Kernel lib))

; call a Ruby method on an Array with a block argument
(defn reduce [f coll]
  (.inject coll | f))

; using Ruby's AMQP gem with an inline block
(.subscribe queue {:ack true} | [metadata payload]
  (puts (str "got a message: " payload))
  (.ack metadata))

What about in Rails?

$ rails console -- -rrouge
Loading development environment (Rails 3.2.6)
1.9.3p194 :002 > Rouge::REPL.repl []

  Content Load (0.7ms)  SELECT "contents".* FROM "contents" WHERE "contents"."id" = 1
