List to text transformation with Clojure and Ruby

gistfile1.clj

; Goal: Turn Array `["foo", "bar", "baz"]` into String `"ordered: 1=foo 2=bar 3=baz"`.

; Clojure

;; Read arguments from command line
;; (def argv *command-line-args*)

;; Fake command-line arguments for use in REPL
(def argv (seque ["foo" "bar" "baz"]))

(println "ordered:"
    (apply str 
        (interpose " " 
            (map 
                #(str (first %) "=" (last %)) 
                (map vector 
                    (iterate inc 0) 
                    argv)))))

# Plain Ruby

%w[foo bar baz].each_with_index do |word, i|
    a << "#{i}=#{word}"
end
puts "ordered: #{a.join(' ')}"

# Ruby with Facets

puts "ordered: " + %w[foo bar baz].map_with_index{|word, i| "#{i}=#{word}"}.join(" ")
