[Phpwiki-talk] MathML plugin

[<mal...@cs...>]

I've written the plugin and got it producing valid MathML, but I
don't seem to be able to get my browser (FireFox) to display it.

The actual Wiki page, produce with the plugin can be seen at:
http://cgi.cse.unsw.edu.au/~malcolmr/bushfire/index.php?pagename=SandBox
The MathML does not display properly.

I have copied the output into the file: /home/malcolmr/public_html/blart.xhtml
if I open this file directly it shows the MathML correctly.

if I access it via the URL http://www/~malcolmr/blart.xhtml, all I see is
the straight xhtml file listing.

I have a copy of the file in /home/malcolmr/public_html/blart.html
if I open this file directly it does not display the MathML correctly.
Likewise if I access it over the web.

I haven't tested this out with IE yet.

I'm not very XHTML-savvy. Does anyone have any ideas how I can get this to 
do the right thing?

Header and namespace wise everything is correct.
But you need this header:
   "Content-Type: application/xhtml+xml"
instead of
   "Content-Type: text/html"
which phpwiki or php sends automatically.

Your server even sends it as text/plain:

$ GET -esSUd http://cgi.cse.unsw.edu.au/~malcolmr/blart.xhtml
GET http://cgi.cse.unsw.edu.au/~malcolmr/blart.xhtml
User-Agent: lwp-request/2.06

GET http://cgi.cse.unsw.edu.au/~malcolmr/blart.xhtml --> 200 OK

and phpwiki:

.....

I'll see what I can do. We need to override the Content-Type for pdf and 
svg also.

And for IE you you to install a plugin, like
MathPlayer (free, requires IE 6.0)
   http://www.dessci.com/en/products/mathplayer/
   Looks fine.
or Techexplorer plugin.

See also http://www.w3.org/Math/XSL/ for the browser matrix.

I've got the MathML plugin working locally. You can see it in operation
on my wiki at:

http://cgi.cse.unsw.edu.au/~malcolmr/bushfire/index.php?pagename=SandBox

I'll tidy it up a bit and see if I can produce a patch in the near future.
The only outstanding problem I know of it that the "preview" mode doesn't
display properly. That is due to a line in editpage.php which sets 
Content-Type to text/html. Unfortunately, when I change this is seems 
to break things, for reasons I don't understand.

One issue: I can't use the plugin to produce inline math. It appears that
plugins only work if they are the first thing on their line. So something
like:

  Applying Bayes Rule: <?plugin ITex2MML $ P(A|B) = P(B|A)P(A) / P(B) $ ?> 
  we see that...

won't work. Is this a deliberate design issue? Looking at the code, it
seems that plugins are only handled by the BlockParser and not the
InlineParser. I suppose this is sensible for most of the existing 
plugins, but it seems limiting.

This was fixed with 1.3.10.
