MathML and BBpress working together

Being both a web nerd and Physics student, I decided it was time for BBpress to meet up with MathML.

Here's the steps I took to get it crankin':
1. Made a copy of the default 'kakumei' template, then renamed the folder 'physics', my new template name. I then put a copy of ASCIImath.js in there. This does all the hard work.
2. Changed the physics/header.php from:
```
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN" "http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" <?php bb_language_attributes( '1.1' ); ?>>
```
  to:
```
<?xml version='1.0' encoding='iso-8859-1'?>
<?xml-stylesheet type="text/xsl" href="http://www.w3.org/Math/XSL/mathml.xsl"?>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1 plus MathML 2.0 plus SVG 1.1//EN" "http://www.w3.org/2002/04/xhtml-math-svg/xhtml-math-svg-flat.dtd" >

<html xmlns="http://www.w3.org/1999/xhtml"
      xml:lang="en"
      xmlns:pref="http://www.w3.org/2002/Math/preference"
      pref:renderer="css">
```
  It'd probably still work if you didn't bother with this step, but seeing as BBpress is making XML we may as well.
3. Added <script type="text/javascript" src="<?php echo bb_path_to_url( dirname(__FILE__) . '/ASCIIMathML.js'); ?>"> to physics/header.php - this loads the ASCIIMathML.js javascript and does a majority of the MathML magic.
4. Opened bb-includes/formattingfunctions.php and edited this:
```
function code_trick( $text ) {
	 $text = str_replace(array("\r\n", "\r"), "\n", $text);
	// $text = preg_replace("|<code>(.*?)</code>|e", "'<code>' . encodeit('$1') . '</code>'", $text);
	// $text = preg_replace("|\n<code>(.*?)</code>|se", "'<pre><code>' . encodeit('$1') . '</code></pre>'", $text);
	return $text;
}
```
  To turn off the backtick code replacement - this is what ASCIIMath.js does!
That was it. I'll zip it all up then post it up here. Ideally, it'd be better to not comment out any of the bb-include/ files - if anyone has any suggestions, let me know.

Oh yeah - you can have a play at http://www.thetelegraphic.com/bbpress/bbpress/
That's really just a sandbox for now and won't be there forever.

I'll be releasing the black template it's using too - It's just Kakumei with a different colour scheme.

Get bbpress + mathML.

This is really just a quick knockup - perhaps MathML support would be best in plugin form? I really didn't do all that much, but I'm not familiar with the BBpress plugin system at all so I'm not sure how easy (if possible), it would be.

Thanks!

You can include ASCIIMathML.js in the header via plugin by this sort of code:

`function incMathJs() {
$url = bb_path_to_url( dirname(__FILE__) . '/ASCIIMathML.js')
echo '<script type="text/javascript" src="' . $url . '">';
}
add_action( 'bb_head', 'incMathJs' );

Not sure when or how the JS kicks in, but perhaps that's not necessary? Anyway, you could head over to trac and request that code_trick be made pluggable (so a plugin could overwrite it).

Ah - so ridiculously easy! I'm liking BBpress more and more ;).

I just requested code_trick to become pluggable too - hopefully that'll happen, and soon, so I can just use a plugin and not hack at core files.

Created a TRAC for it and it is in your other thread!
