Instructions for enabling itex2MML for WordPress 2.3
These are my temporary notes on how I have enabled itex2MML for my WordPress 2.3 installation. These instructions are based on the work of Frederick Leitner and Jacques Distler
WordPress 2.3 file changes
I have been able to enable itex2MML for WordPress 2.3 by doing the following changes:
- wp-includes/classes.php
- wp-includes/formatting.php
- the header creator in your theme must be changed.
- itexToMML must be updated to latest recommendations of the W3C.
- plugin for WordPress by Jacques Distler
Changes to wp-includes/classes.php
The function send_headers was modified. Here is the diff between the official release and my changes:
174,176d173
< if ( !is_user_logged_in() )
< nocache_headers();
< @header('Content-type: ' . get_option('html_type') . '; charset=' . get_option('blog_charset'));
178c175,183
< @header('Content-type: ' . get_option('html_type') . '; charset=' . get_option('blog_charset'));

Changes to wp-includes/formatting.php
The choice 'math' must be erased from the 'allblocks' variable.
