ruby syntax extension: double is {|x| x*2}; fib is memoized {|n| n<2 ? 1 : fib(n-2)+fib(n-1)}

RubyIs

Define small functions easier!

Usage

require 'ruby_is'

ruby is { :awesome }
ruby #=> :awesome

rubies are {|how| "#{how} awesome"}
rubies "totally" # => "totally awesome"

inc is ->(a){ puts "calculating #{a}"; a+1 }
inc 42 #=> "calculating 42"; 43

inc_m is always {|a| inc a }
# inc_m is memoized {|a| inc a } # this also works
inc_m 42 #=> "calculating 42"; 43
inc_m 42 #=> 43
inc_m 10 #=> "calculating 10"; 11

inc_m is cached(1) {|a| inc a }
# inc_m is cached(1.second) {|a| inc a }  # if active_support/time have been enabled
inc_m 42 #=> "calculating 42"; 43
inc_m 42 #=> 43
sleep 2
inc_m 42 #=> "calculating 42"; 43
