Rouge Build Status

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.

Install the gem to get the local REPL:

gem install rouge-lang

rouge

You’ll see the user=> prompt. Enjoy!

example

See boot.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 4.0.1)
