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.
As with Paul Gartside's original version,
http://pear.math.pitt.edu/mathzilla/itex2mmlBugs.html
itex2MML is Open Source software, released under a dual license: GPL and MPL.
