Ruby regex tricks

regex_var.rb

# variables from regex
# must be literal; must be on left side of comparison

if /Robin is (?<adjective>\w+)/ =~ "Robin is awesome" then
  puts "#{adjective}"
end

# indexing into a string via regex (whoa)

str = "Robin is awesome"
adjective = str[/Robin is (?:\w+)/, 1]

# or

adjective = str[/Robin is (?<adjective>\w+)/, :adjective]
