1) Because enabling native MathML now requires special configuration steps
from the users, they can as well just check their math font setup. Hence we
remove the Web font fallback.
2) We then can actually just remove ext.math.desktop.css since no specific
style is necessary any more on desktop.
3) We also no longer need to add the Web font to the list of font-family on
the <math> element. We actually just remove the whole font-family rule so
that it is up to web engines developers & users to decide the best math font
to use (e.g. via the "Fonts for mathematics" option in the font preference
menu of Firefox).
Change-Id: I1818d288b0f28715a460e3163590e4d0374c42b4
This version (for MediaWiki 1.19) has some changes since previous versions:
* rendering options have been reduced to just 'Always PNG' and 'Leave it as TeX'
** all other rendering options will merge to PNG.
* initial experimental support for integrating MathJax client-side rendering
See the README in the math subdirectory for more info on setting up the
low-level conversion tools.
See the README in the texvccheck subdirectory for more info on setting up the
security checking tools for MathJax and LaTeXML.
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
$wgMathUseLaTeXML = true;
It is possible to choose LaTeXML as default option (for anonymous user) by setting
$wgDefaultUserOptions['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.
Furthermore, a core version of wmf/1.22wmf7 or newer is recommended.
Otherwise, errors in LaTeXML can lead to mal-formatted XML output and disturb the
page layout.
MathJax configuration:
Client-side configuration of MathJax can be done by specifying a mathJax.config
table, which takes a table as described in:
http://docs.mathjax.org/en/v1.1-latest/options/index.html#configuration
Example:
if ( typeof mathJax === 'undefined' ) {
mathJax = {};
mathJax.config = {
showProcessingMessages: true
};
}
Attributes of the <math /> element:
attribute "display":
possible values: "inline", "block" or "inline-displaystyle" (default)
"display" reproduces the old texvc behavior:
The equation is rendered with large height operands (texvc used $$ $tex $$ to render)
but the equation printed to the current line of the output and not centered in a new line.
In Wikipedia users use :<math>$tex</math> to move the math element closer to the center.
"inline" renders the equation in with small height operands by adding {\textstyle $tex } to the
users input ($tex). The equation is displayed in the current text line.
"inline-displaystyle" renders the equation in with large height operands centered in a new line by adding
{\displaystyle $tex } to the user input ($tex).
For testing your installation run
php tests/phpunit/phpunit.php extensions/Math/tests/
from your MediWiki home path.
== Logging ==
The math extension supports PSR-3 logging:
Configuration can be dona via
$wgDebugLogGroups['Math'] = [ 'level' => 'info', 'destination' => '/path/to/file.log' ];
