Implement MathJax support
* lisp/org-exp.el (org-export-with-LaTeX-fragments): New default t, which now means to use MathJax processing for HTML. Also allow new value `dvipng' to force the old image processing. (org-infile-export-plist): Parse for MATHJAX setup line. * lisp/org-html.el (org-export-html-mathjax-options): New option. (org-export-html-mathjax-config): New function. (org-export-html-mathjax-template): New option. (org-export-html-preprocess): Call the LaTeX snippet processor with an additional argument to declare special ways of processing. (org-export-as-html): Bind the dynamical variable `org-export-have-math'. Insert the MathJax script template when it is needed by the document. * lisp/org.el (org-preview-latex-fragment): Call `org-format-latex' with the additional processing argument. (org-export-have-math): New variable, for dynamic scoping. (org-format-latex): Implement specific ways of processing. New function argument for processing type. (org-org-menu): Remove the entry to configure LaTeX snippet processing. MathJax is now the default for displaying math in a browser.

With symbols, sub- and superscripts, HTML is pretty much at its end when
|
||||
it comes to representing mathematical formulas@footnote{Yes, there is
|
||||
MathML, but that is not yet fully supported by many browsers, and there
|
||||
is no decent converter for turning La@TeX{} or ASCII representations of
|
||||
formulas into MathML. So for the time being, converting formulas into
|
||||
images seems the way to go.}. More complex expressions need a dedicated
|
||||
formula processor. To this end, Org-mode can contain arbitrary La@TeX{}
|
||||
fragments. It provides commands to preview the typeset result of these
|
||||
fragments, and upon export to HTML, all fragments will be converted to
|
||||
images and inlined into the HTML document@footnote{The La@TeX{} export
|
||||
will not use images for displaying La@TeX{} fragments but include these
|
||||
fragments directly into the La@TeX{} code.}. For this to work you
|
||||
need to be on a system with a working La@TeX{} installation. You also
|
||||
need the @file{dvipng} program, available at
|
||||
@url{http://sourceforge.net/projects/dvipng/}. The La@TeX{} header that
|
||||
will be used when processing a fragment can be configured with the
|
||||
variable @code{org-format-latex-header}.
|
||||
Going beyond symbols and sub- and superscripts, a full formula language is
|
||||
needed. Org-mode can contain La@TeX{} math fragments, and it supports ways
|
||||
to process these for several export backends. When exporting to La@TeX{},
|
||||
the code is obviously left as it is. When exporting to HTML, Org invokes the
|
||||
@uref{http://www.mathjax.org, MathJax library} (@pxref{Math formatting in
|
||||
HTML export}) to process and display the math@footnote{If you plan to use
|
||||
this regularly or on pages with significant page views, you should install
|
||||
@file{MathJax} on your own server in order to limit the load of our server.}.
|

Finally, it can also process the mathematical expressions into
|
||||
images@footnote{For this to work you need to be on a system with a working
