WWW::Shorten::URLchen - Perl interface to URLchen.de

SYNOPSIS

Top

  use WWW::Shorten 'URLchen';

  $short_url = makeashorterlink($long_url);
  $long_url  = makealongerlink($short_url);

DESCRIPTION

Top

A Perl interface to the web site urlchen.de. URLchen simply maintains a database of long URLs, each of which has a unique identifier.

Functions

Top

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

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

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

EXPORT

makeashorterlink, makealongerlink
