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

If you are using Ruby 2.4 or later, there are String#match?(regex) and Regexp#match?(string) methods that return booleans without the conversion shenanigans (where needed, usually not), and have improved performance to boot.
