Interwiki Links

Variation for 8.08.2

The interwiki template is written for 9.02, but something can also be achieved with 8.08.  Note this variation does not set a class attribute on the link to allow for customization of the link look-and-feel.  Also note that you will need to invoke it using the template prefix: {{ template.interwiki('wikipedia', 'MindTouch') }}

var prefix = string.ToLower($0 ?? $prefix ?? '');
var path = $1 ?? $path;
var title = $2 ?? $title ?? path;

switch(prefix) {
case 'wikipedia':
    web.link(uri.build('http://en.wikipedia.org/wiki', path), title, title);
    break;
default:
    'Unknown prefix: ' .. prefix .. '.';
}
