Template::Plugin::Clickable(3pm)			User Contributed Perl Documentation			  Template::Plugin::Clickable(3pm)

NAME
Template::Plugin::Clickable - Make URLs clickable in HTML SYNOPSIS
[% USE Clickable %] [% FILTER clickable %] URL is http://www.tt2.org/ [% END %] this will become: URL is <a href="http://www.tt2.org/">http://www.tt2.org/</a> DESCRIPTION
Template::Plugin::Clickable is a plugin for TT, which allows you to filter HTMLs clickable. OPTIONS
target [% FILTER clickable target => '_blank' %] [% message.body | html %] [% END %] "target" option enables you to set target attribute in A links. none by default. finder_class "finder_class" option enables you to set other URI finder class rather than URI::Find (default). For example, [% FILTER clickable finder_class => 'URI::Find::Schemeless' %] Visit www.example.com/join right now! [% END %] this will become: Visit <a href="http://www.example.com/join">www.example.com/join</a> right now! NOTE
If you use this module with "html" filter, you should be careful not to break tags or brackets around the URLs. For example if you have a following URL form, <http://www.example.com/> Clickable plugin will filter this into: <a href="http://www.example.com/"><http://www.example.com/></a> which is bad for HTML viewing. However, if you HTML filter them first and then clickable filter, you'll get: &lt;<a href="http://www.example.com/&gt">http://www.example.com/&gt</a>; which href part is wrong. You'd better try Template::Plugin::TagRescue in this case. [% USE Clickable -%] [% USE TagRescue -%] [% FILTER html_except_for('a') -%] [% FILTER clickable -%] <http://www.example.com/> [%- END %] [%- END %] will give you the right format. AUTHOR
