@ -7,6 +7,16 @@ This version (for MediaWiki 1.19) has some changes since previous versions:
|

See the README in the math subdirectory for more info on setting up the
|
||||
low-level conversion tools.
|
||||
|
||||
MathML support:
|
||||
If you prefer MathML rather than images you can use LaTeXML to convert the
|
||||
math tags to MathML. To use that feature you have to enable LaTeXML by setting
|
||||
$wgUseLaTeXML = true;
|
||||
It is possible to choose LaTeXML as default option (for anonymous user) by setting
|
||||
$wgDefaultUserOptions['math'] = MW_MATH_LATEXML;
|
||||
in the LocalSettings.php file.
|
||||
The LaTeXML option requires php5-curl to be installed. Without php5-curl no proper
|
||||
error handling can be guaranteed.
|
||||
|
||||
MathJax configuration:
|
||||
Client-side configuration of MathJax can be done by specifying a mathJax.config
|
||||
table, which takes a table as described in:
