Ruby: What's the proper syntax for a boolean regex method?

Question

What is the proper syntax for a method that checks a string for a pattern, and returns true or false if the regex matches?

Basic idea:

def has_regex?(str         


        

Answer 1

For anyone's future reference, double bangs are frowned upon from bbatsov's ruby style guide. Instead of using a double bang, just check if the value isn't nil. If the value isn't nil, it exists.

Instead of doing this:

def has_regex?(string)
  !!(string =~ /something/i)
end

You can always do this:

def has_regex?(string)
  !(string =~ /something/i).nil?
end
