Ok, I’ve been poking around the forums, found out how to get new allowed tags (thanks to Louise Dade + others) and now want to add MathML tag support, so users can post MathML.

A big problem is that the editor box seems to add line break <br /> tags to every line – how do you turn this off?

The array I’m using in the plugin is:

`$tags = array(

// XHTML elements:

'a' => array(

'href' => array(),

'hreflang' => array(),

'title' => array(),

'rel' => array(),

'xml:lang' => array()),

'abbr' => array('title' => array()),

'acronym' => array('title' => array()),

'b' => array(),

'bdo' => array(

'dir' => array(),

'xml:lang' => array()),

'blockquote' => array('cite' => array()),

'br' => array(),

'code' => array(),

// 'del' => array('datetime' => array()),

'dd' => array(),

'dl' => array(),

'div' => array(

'dir' => array(),

'xml:lang' => array()),

'dt' => array(),

'em' => array(),

'i' => array(

'dir' => array(),

'xml:lang' => array()),

// 'ins' => array('datetime' => array(), 'cite' => array()),

'li' => array(),

'ol' => array(),

'p' => array(),

'pre' => array(),

// 'q' => array(),

// 'strike' => array(),

'span' => array(

'dir' => array(),

'xml:lang' => array()),

'strong' => array(),

'sub' => array(),

'sup' => array(),

'u' => array(),

'ul' => array(),

// MathML elements:

'math' => array(

'xmlns' => array(),

'mode' => array()),

'mo' => array(

'lspace' => array(),

'rspace' => array(),

'fence' => array(),

'separator' => array()),

'mi' => array('mathvariant' => array()),

'msub' => array(),

'msup' => array(),

'msubsup' => array(),

'mfrac' => array('linethickness' => array()),

'mn' => array(),

'mstyle' => array(

'scriptlevel' => array(),

'fontstyle' => array(),

'fontweight' => array(),

'mathvariant' => array(),

'displaystyle' => array()),

'mtext' => array(),

'mspace' => array(

'width' => array(),

'height' => array(),

'depth' => array()),

'msqrt' => array(),

'mmultiscripts' => array(),

'mprescripts' => array(),

'none' => array(),

'mroot' => array(),

'mphantom' => array(),

'merror' => array(),

'mover' => array(),

'munder' => array(),

'munderover' => array(),

'maction' => array(

'actiontype' => array(),

'other' => array(),

'selection' => array()),

'mtable' => array(

'align' => array(),

'columnalign' => array(),

'rowalign' => array(),

'equalrows' => array(),

'equalcolumns' => array(),

'columnspacing' => array(),

'rowspacing' => array(),

'columnlines' => array(),

'rowlines' => array(),

'frame' => array()),

'mrow' => array(

'xlink:type' => array(),

'xlink:show' => array(),

'xlink:href' => array()),

'mtr' => array(

'rowalign' => array(),

'columnalign' => array()),

'mtd' => array(

'rowspan' => array(),

'columnspan' => array(),

'rowalign' => array(),

'columnalign' => array()),

'mpadded' => array('width' => array())

);

return $tags;

}`

If anyone’s interested, you can find install at http://www.thetelegraphic.com/bbpress/bbpress/ (for now, once it’s fully working it’ll go to a dedicated domain).

My guess would be that it would be in /bb-includes/formatingfunctions.php somewhere, but I am not sure….

I’ve found a way around this finally, and will be posting up a ‘math-pack’ version of BBpress. I did have to edit /bb-includes/formattingfunctions.php (2 lines – commented out a regular expression).

Basically, the way I came up with was using ASCIIMath.js to replace stuff in backticks. I’ll get a zip up when I have the time (actually hacing to do the maths uses up most of my time)
