in reply to Question on evaulating a user built regex

What you need to do is place the regex inside the m// operator, then print the match. If you are trying a substitution, then use the s// operator. Eval is unnecesarry.

$user_text =~ m/$user_regex/;
print $&;

    I'm letting the user build the expression, including the regex operator so I need a way for the string to be evaluated at runtime as a regex.

      Then you'll want eval "\$user_text =~ $regex".
