Question

I am looking for a way to find a url in a string and convert it to a link.

The url may be anywhere in the string (beginning, middle, or the end).

Regex is preferred but CPAN modules are welcome.

You can use Regexp::Common to find the string and then do a substitution to make it into a links.
In the absence of any thing else I have used the URL as the link text.

    use Regexp::Common "URI";
    my $string="Some text containing http://stackoverflow.com/questions/4587876/perl-convert-url-string-to-link in middle" ;

    $string =~    s( ($RE{URI}{HTTP}) )
                  (<a href="$1">$1</a>)gx  ;

    print $string ;
