I'm writing a simple script to view Twitter tweets but I'm having trouble converting URLs (http://...) into HTML anchors.

I need a pure Perl solution, I can't use a package, it must be a reg exp.

Here's what I have so far, clearly not working.

#!/usr/bin/perl

$tweet = 'Mayor Nickels leads the pack as Seattle campaign contributio
+ns break $1 million mark http://tinyurl.com/ckpxmu #seattle #seattlen
+ews';
$_ = $tweet;
s/(http.*)/<a href=\"\1\">\1<\/a>/;
print $_ . "\n";
[download]

I need the regular expression to stop when it hits white space, in this example not including the hashtags (#seattle #seattlenews).

I just don't know how to do that. Needless to say my regular expression knowledge is limited to only the most basic operations.

Thanks,
Keith

• Are you posting in the right place? Check out Where do I post X? to know for sure.
• Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:

  <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>

• Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
• Want more info? How to link or How to display code and escape characters are good places to start.
