/itexToMML

INTRODUCTION:

This package contains the distribution for itex2MML. Binaries for MacOSX and

Linux are provided in the itex-binaries directory. The source code is in the

itex-src directory. It should compile on most platforms by simply typing

     make

     sudo make install

The resulting itex2MML binary is a stream filter. It takes text with embedded

itex equations on STDIN, converts the itex equations to MathML, and outputs

the resulting text on STDOUT.

Also included are Ruby bindings. They require GNU make and SWIG 1.3, and can be

built with

     make ruby

     make test_ruby

     sudo make install_ruby

The Ruby module provides four public methods

       itex.html_filter(a_string)

               converts all itex equations in a_string to MathML, passing the

               rest of a_string unmodified. Returns the converted string. 

       itex.filter(a_string)

               converts all itex equations in a_string to MathML. Returns just

               the MathML equation(s), as a string.

       itex.inline_filter(a_string)

               treats a_string as an inline equation (automatically supplies

               the surrounding $...$, so you don't have to) and converts it

               MathML. Returns the MathML inline equation, as a string.

       itex.block_filter(a_string)

               treats a_string as a block equation (automatically supplies

               the surrounding $$...$$, so you don't have to) and converts it

               MathML. Returns the MathML block equation, as a string.

Finally, there is a MovableType (2.6 or greater) plugin which provides two

Text Filtering options:

1) itex to MathML

2) itex to MathML with parbreaks

The plugin relies on the itex2MML commandline utility to do the actual

conversion. The first filter is a straight itex2MML translation. The latter

uses the "TeX" (and blogger's) convention that two linebreaks in succession

signify a new paragraph. (The bloggers also like to convert single linebreaks

to <br />, but that would mess with TeX formula entry, so we don't support it.)

A second plugin (also included) provides additionalText Filtering options:

1) Textile with itex to MathML

2) Markdown with itex to MathML

Details describing this plugin are available at: 

    http://golem.ph.utexas.edu/~distler/blog/archives/000374.html

It requires both the itex2MML plugin and the Textile and/or Markdown plugins.

See

      http://golem.ph.utexas.edu/~distler/blog/itex2MMLcommands.html

and Paul Gartside's page

      http://pear.math.pitt.edu/mathzilla/itex2mml.html

for more details on composing in itex and using the itex2MML program.

The version of itex2MML included here is greatly-enhanced, with

many bugfixes and support for a larger subset of LaTeX/AMSLaTeX syntax.

Below I've put some simple notes specific to the use of this plugin.

USAGE NOTES:

1) Tex equations are delimited by $...$ (inline) or \[...\] (display).

Alternatively, $$...$$ can also be used to delimit display equations. So,

just as in a TeX document, be sure you don't have any free-floating $'s

in your text. If you want to enter something that renders as a $, use

the unicode entity $.

2) The itex2MML stream filter does not distinguish between $$...$$ and \[...\].

Both result in display equations. However, the MovableType plugin and Maruku

    http://maruku.rubyforge.org/

the Ruby Markdown implementation, do distinguish between them. Both have

automatic equation-numbering: \[...\] results in a numbered equation. You

can add an optional label

    \[...\label{foo}...\]

and then you can refer to the equation with either (eq:foo) or \eqref{foo}.

These are automatically turned into hyperlinks.

2) If you are using the "itex to MathML with parbreaks" filter, paragraph

breaks are inserted automatically, whenever you insert a blank line in your

text.  If you are using the plain "itex to MathML" filter, you need to put

in the paragraph (and any other) XHTML tags yourself.

3) Mozilla only renders MathML when you serve the document as XML (ie

using the MIME type application/xhtml+xml rather than text/html). You had

better be producing 100% valid XHTML if you want to see *anything* when Mozilla

is operating in that mode.

4)The best way to serve up XML to Mozilla, while still catering to

other browsers is to use mod_rewrite rules in the .htaccess file of your

blog. See

    http://golem.ph.utexas.edu/~distler/blog/archives/000167.html

for how to do that.

PLUGIN INSTALLATION INSTRUCTIONS:

1) Put the contents of the plugins directory into your MovableType plugins

directory.

2) If you are running MacOSX or Linux, I've provided a precompiled binary,

so you can skip to step 3).

If these don't do the trick for you, or if you prefer to compile your own,

cd into the itex-src directory and type "make". The result should be an itex2MML

binary for your architecture.

3) Copy itex2MML into /usr/local/bin/, and make sure it's executable

(mode 755). If you're building from source, you can achieve this by typing

"make install". If you decide to put it in another location, edit

itex2MML.pl to reflect its new location.
