I was looking around and toying with [ASCIIMathPHP](http:// www.jcphysics.com/ASCIIMath/) and integrated it with MultiMarkdown and my xhtml2latex XSLT transforms.
You can include math as an inline formula by using a markup similar to inline code, such as ``x^2 + y^2 = 1`` (note the double ``).
You can include a formula as a separate paragraph in the same way, or with a leading tab like:
`x_(1,2) = (-b+-sqrt(b^2-4ac))/(2a)`
(Note the single use of ` when prefaced by a tab)
The leading tab is not required, but is allowed as I suspect most
people would like to be able to indent the formula to distinguish it
from regular text, and don't want it interpreted as a code block.
The processing occurs in a several steps:1) ASCIIMathPHP is run on the source markdown document converting the formulas into MathML blocks.
2) MultiMarkdown is then run in the usual manner, with or without SmartyPants
3) You can then optionally use XSLT to transform the XHTML into LaTeX or whatever by using an updated version of my xhtml2latex, or your own XSLT files. This includes the use of [XSLT MathML Library] (http://xsltml.sourceforge.net/) to convert the MathML into LaTeX.
This allows you to generate XHTML with embedded MathML, or to generate LaTeX source with the math properly displayed. More importantly, it allows you to use ASCIIMath to enter your formulas which is MUCH more human readable than either MathML or LaTeX.
THE PROBLEMI have run into a couple of snags, that I am sure would be quite simple to fix if I knew more about XHTML and XSLT. To demonstrate, I have included a sample plain text file (.txt), as well as two versions of XHTML output - (.xhtml and .html) and a LaTeX file (.tex). These were all generated automatically from the source plain text file.
The .xhtml setup was designed using the layout from http:// www.mozilla.org/projects/mathml/authoring-example.xhtml
It renders properly in Firefox (with the exception of that ugliness in square root signs, but that is not my doing...), but I cannot use this to go through my xhtml2latex.xslt workflow. It appears that the problem lies in the xmlns attribute:
<html xmlns="http://www.w3.org/1999/xhtml";>
If I remove that attribute, the xsltproc stuff works fine.
The .html file is built using the usual DOCTYPE etc from
MultiMarkdown. It does not render properly in Firefox, but it DOES
go through my xhtml2latex.xslt files properly, to generate valid
LaTeX output (i.e. the .tex file).
Also, if I take the .xhtml file and rename it with a .html extension, it no longer renders properly in Firefox.
Once you have the .tex file, it goes without a snag through pdflatex to generate a pdf.
REQUEST FOR HELP!!!I would appreciate any input available in how to smooth this process a bit, specifically:
1) How can I create a valid document with a .html extension? (requiring .xhtml is going to break a bunch of other stuff)
2) How do I fix my xhtml2latex stylesheets (http://
fletcher.freeshell.org/wiki/Markdown_and_XML) to work with a file
that has the xmlns attribute applied to the html node? (Or with
whatever comes out of an answer to #1 above)
3) Any suggestions on the markup syntax? I sort of arbitrarily chose the use of an extra `. I am sure there is a better way of doing this, and would love to hear input.
4) And less importantly, is there a perl version of ASCIIMath out
there somewhere? It would be great to be able to combine the code,
but this can be worked around. Definitely lower on the priority list.
Once I get all of this working more smoothly, I will release the updated software for public use. For now, you can see how it works with sample documents
Thanks in advance! FletcherPS> Yes, I realize that the included mathematical equations are not all correct. It's just a demo...

Title: Sample MultiMarkdownMath Document
# Math Testing #
You can use math in-line, such as ``8 + 4 = 12`` and ``155 / 12 = 10 / 2``.
Or you can use as paragraphs:
``155 / 12 = 10 / 2``
``x^2 + y^2 = 1``
Or with a blockquote-like syntax:
`x_(1,2) = (-b+-sqrt(b^2-4ac))/(2a)`
Code is not translated: `x = pi`
