=head1 NAME 

Kwiki::ShortcutLinks - WAFL-phrase shortcuts for arbitrary web links

=head1 SYNOPSIS

 $ cpan Kwiki::ShortcutLinks
 $ cd /path/to/kwiki
 $ echo "Kwiki::ShortcutLinks" >> plugins
 $ kwiki -update
 $ vi shortcuts.yaml
 $ kwiki -update

=head1 DESCRIPTION

This plugin allows the Kwiki maintainer to define a series of short-cut 
wafl phrases via a simple config file.

When the plugin is installed and added to Kwiki via C<kwiki -update>,
a default C<shortcuts.yaml> file is created.  This can be edited and
added to as necessary.  C<kwiki -update> must be run again after
adding, renaming or deleting shortcuts.

The example entry:

  google:   http://www.google.com/search?q=

adds support for the wafl phrase C<{google:...}>, for example:

  Search Google for: {google:Kwiki}

will render as:

  Search Google for: <a href="http://www.google.com/search?q=Kwiki">Kwiki</a>

If the short-cut definition contains extra words, these will be
prepended to the rendered link.  For example:

  rt:       http://ticket-serv/Ticket/Display.html?id= RT Ticket

will render C<{rt:1234}> as:

  <a href="http://ticket-serv/Ticket/Display.html?id=1234">RT Ticket 1234</a>

If you follow the shortcut argument by a pipe and some more text, that text
will be used for the link text, instead of the argument and any leader.  So,
for the above definition of C<rt>, C<{rt:1234|A Hateful Problem}> would render
as:

  <a href="http://ticket-serv/Ticket/Display.html?id=1234">A Hateful Problem</a>

The shortcut can contain the string C<%s>, which will be replaced by
the wafl phrase arguments.  (If there is no C<%s>, the arguments are
appended to the shortcut expansion, as in the examples above.)  So the
config entry:

  wikipedia: http://www.wikipedia.org/w/wiki.phtml?search=%s&go=Go

and the shortcut C<{wikipedia:Cambridge}> will render as

  <a href="http://www.wikipedia.org/w/wiki.phtml?search=Cambridge&go=Go">Cambridge</a>
