Hi,
I'm adding a syntax pluging to handle some special mark up that comes in
two forms -
<card >Some stuff</card>
<card some="stuff" />
These need different handling so I'm adding patterns the Lexer as -
function connectTo($mode) {
$this->Lexer->addEntryPattern('<card.*?[^\/]>', $mode,
'plugin_6d6v2_card');
$this->Lexer->addExitPattern('<\/card>', 'plugin_6d6v2_card');
$this->Lexer->addSpecialPattern('<card.*?\/>', $mode,
'plugin_6d6v2_card');
}
But this throws up an error -
PHP Warning: preg_match() [<a
href='function.preg-match'>function.preg-match</a>]: Unknown modifier
']' in .../inc/parser/lexer.php on line 115
and the plugin's handle function is not not triggered.
The general PHP advice for the error is to use delimiters around the
expression but this is not allowed in the Lexer (according to the wiki).
What regular expression should I be using so that '<card >' will be
flagged as an entry pattern but not '<card />'?
Thanks
Chris
