Except that it doesn't work and my knowledge of how classes work in PHP
is insufficient.
Doing:-
$this->render('wiki text string');
in a syntax plugin just tries to call the plugin's own render:-
function render($mode, &$renderer, $data)
and of course produces a run time error. As far as I can see syntax
plugins extend DokuWiki_Syntax_Plugin and DokuWiki_Syntax_Plugin extends
Doku_Parser_Mode which seems to be a parent/top-level class. I'm not
quite clear *what* the plugin base class is parent of.
.... ah!! It should be:-
$renderer->render('wiki text string');
Where $renderer is the second parameter passed into the plugin's
render() function.
