NAME ^

WWW::Shorten - Interface to URL shortening sites.

SYNOPSIS ^

  use WWW::Shorten 'Linkz';
  use WWW::Shorten 'MakeAShorterLink';
  use WWW::Shorten 'Metamark';
  use WWW::Shorten 'NotLong';
  use WWW::Shorten 'OneShortLink';
  use WWW::Shorten 'Shorl';
  use WWW::Shorten 'TinyClick';
  use WWW::Shorten 'TinyLink';
  use WWW::Shorten 'TinyURL';

  # Individual modules have have their
  # own syntactic variations.

  # See the documentation for the particular
  # module you intend to use for details, trips
  # and traps.

  $short_url = makeashorterlink($long_url);

  $long_url  = makealongerlink($short_url);

  # If you don't like the function names:
  use WWW::Shorten 'Metamark', ':short';
  $short_url = short_link( $long_url );
  $long_url = long_link( $short_url );

ABSTRACT ^

A Perl interface to URL shortening sites. These sites maintain databases of long URLs, each of which has a unique identifier.

DESCRIPTION ^

The function makeashorterlink will call the relevant web site passing it your long URL and will return the shorter version.

The function makealongerlink does the reverse. makealongerlink will accept as an argument either the full shortened URL or just the identifier.

If anything goes wrong, then either function will return undef.

Subroutines ^

import

Called when the module is used. Loads the correct sub-module

EXPORT

makeashorterlink, makealongerlink

Or, if you specify :short on the import line, you instead get short_link and long_link. If you explicitly want the default set, use :default.

Actually these functions are exported from the relevant subclass.

COMMAND LINE PROGRAM ^

A very simple program called shorten is supplied in the distribution's bin folder. This program takes a URL and gives you a shortened version of it.

EXAMPLES and PROGRAMS ^

Adam Kessel wrote shorlfilter, a program that uses WWW::Shorten to filter a file, converting long URLs to short ones.

    http://bostoncoop.net/adam/shorlfilter

There is also a bin directory in this distribution which contains a sample program.

NO LONGER SUPPORTED ^

The URL-shortening industry is pretty volatile. Many sites exist for a while and then go away. The most famous of those is probably Make A Shorter Link (the site that originally inspired this suite of modules). MASL has been acquired by TinyURL.com and no longer exists.

Here is a list of sites that were once supported by this module and are no longer with us:

MakeAShorterLink
BabyURL
EkDk
qURL (although the differently capitalised Qurl.com now uses their old domain)
ShortLink
SmLnk
URLjr
V3

See Joshua Schachter's blog entry at http://joshua.schachter.org/2009/04/on-url-shorteners.html for some very interesting discussion on some problems that can be caused by the volatility of this part of the web industry.

RELATED MODULES ^

Similar Aim

WWW::MakeAShorterLink is what this module was originally based upon. That module is obsoleted by WWW::Shorten::MakeAShorterLink, one of the many subclasses of WWW::Shorten. Of course, with the demise of Make A Shorter Link, neither the obsolete module nor its replacement are of any use.

Same Area, Different Purpose

CGI::Shorten provides building blocks for you to create your own URL shortening service. It provides routines to shoretn a URL, lengthen one, and it keeps a store. Nice and easy.

BUGS, REQUESTS, COMMENTS ^

Support for this module is supplied using the CPAN RT system via the web or email:

    http://rt.cpan.org/NoAuth/ReportBug.html?Queue=WWW-Shorten
    ( shorter URL: http://xrl.us/rfb )

    bug-www-shorten@rt.cpan.org

This makes it much easier for me to track things and thus means your problem is less likely to be neglected.
