Is there a function like String#scan, but returning array of MatchDatas?

Question

I need a function to return all matches of a regexp in a string and positions at which the matches are found (I want to highlight matches in the string).

Answer 1

Do you really need the position or is it enough to replace the matches on the fly?

s="I'mma let you finish but Beyonce had one of the best music videos of all time!"
s.gsub(/(Beyonce|best)/, '\1')

=> "I'mma let you finish but Beyonce had one of the best music videos of all time!"
