Porting perl regexp to ruby

Ruby
1

I have a perl regexp that strips c++ comments (I have not constructed
this myself, found it here:
Perl Documentation - Perldoc Browser ). However, it
uses the ‘e’ modifier that will take the replacement value and evaluate
it. How do I get similar functionality in ruby?

perl regexp below:
s#//(.)|/*[^]*+([^/][^]*+)/|“(\.|[^”\])“|‘(\.|[^’\])‘|[^/"’]+#
$1 ? "/$1 */” : $& #ge;

Look at the documentation for gsub. Specifically the block form.

e.g.:

string.gsub(/regex/) { |matched_string| code_to_evaluate }
