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

To make it return true/false switch the position of pattern and string and use case equality ===

def has_regex?(string)
    pattern = /something/i
    return pattern === string
end

I absolutely needed it to return true boolean value and digged around. It is actually documented in regexp class http://www.ruby-doc.org/core-2.1.3/Regexp.html#method-i-3D-3D-3D
