Ruby: Titleize: How do I ignore smaller words like 'and', 'the', 'or, etc

Question

def titleize(string)
  string.split(\" \").map {|word| word.capitalize}.join(\" \")
end

This titleizes every single word, but how do I capture cert

Answer 1

This is pretty straightforward, just add a condition when you call captalize:

$nocaps = ['Jack', 'Jill']

def titleize(string)
  string.split(" ").map {|word| word.capitalize unless $nocaps.include?(word)}.join(" ")
end

The global variables are contrived for this example, it would probably be an instance variable in your real application.
