The Math extension provides support for rendering mathematical formulae. An overview of what can currently be done with this extension is found at the English Wikipedia's documentation.

More information about installing and configuring this extension, including for older versions, can be found at Extension:Math/advancedSettings .

Képletek megjelenítése

The Math extension tries to deliver MathML output, with fallback to images in SVG (converting characters to <path>s) or PNG (least preferentially). Depending on the capabilities of the device you are using, the sort of output is chosen. Basic math support works for all browsers. However, for optimal rendering specific tuning may be needed:

Accessibility support is provided by the VoiceOver screen reader but not by Orca yet.

Telepítés

  • Vagrant használata esetén telepítsd a vagrant roles enable math --provision paranccsal
Kézi telepítés
  • Töltsd le a kiterjesztés fájljait, és mentsd el az extensions/ mappán belüli Math könyvtárba.
  • Add hozzá az alábbi sort a LocalSettings.php fájl aljához:
    wfLoadExtension( 'Math' );
    // See below for installation requirements and configuration settings:
    
  • Futtasd le a frissítőszkriptet, ami automatikusan létrehozza a kiterjesztés által igényelt táblákat az adatbázisban.
  • To see math beyond a plain text output, follow instructions below for enabling various math output modes.
  •   Kész – A Special:Version oldalon ellenőrizheted, hogy a kiterjesztés ténylegesen feltelepült-e.

You should additionally go to the page Special:MathStatus to see whether all of the components of the Math extension now work. For any problems you see, the best option is to create a task on https://phabricator.wikimedia.org

Unfortunately, there is no well tested guide on installing Mathoid and RESTBase to work with the Math extension, but there is at least a working draft. Extension:Math/Restbase please contribute.

In addition, there is a Guide for Installing and Setting up Mediawiki with Restbase and Mathoid in MW1.28.

Math output modes

The setting $wgMathValidModes holds an array with the names of output modes that can be used for rendering. If multiple modes are enabled, logged-in users can set a personal preference in the appearance pane of their user preferences page.

You can also use the $wgDefaultUserOptions setting to set which of these modes should be the default, e.g.:

$wgDefaultUserOptions['math'] = 'mathml';

Mathoid

Mode: 'mathml' (pre-July 2015: MW_MATH_MATHML)

For MW 1.23 and higher, you can use a Mathoid server that uses MathJax to convert texvc input on the server side to MathML+SVG rendering. This is the most recommended option; Mathoid is the rendering mode that will be used on Wikipedia in the future.

Mathoid as a service

To use Mathoid as a service, resulting in performance benefits, the following settings are recommended:

// Set MathML as default rendering option
$wgDefaultUserOptions['math'] = 'mathml';
$wgMathFullRestbaseURL = 'https://en.wikipedia.org/api/rest_';
$wgMathMathMLUrl = 'https://mathoid-beta.wmflabs.org/';

See Mathoid for instructions on how to run your own Mathoid server. Note that as of March 2017 this is likely to also require a RESTBase server/installation (see task T154394).

Mathoid's CLI interface

To use Mathoid's CLI interface, which is possibly easier to set up and resulting in less permanent memory consumption, while degrading performance, the following settings are recommended:

// Set MathML as default rendering option
$wgDefaultUserOptions['math'] = 'mathml';
// Please create a config.yaml in advance. Templates are in the Mathoid repository.
$wgMathoidCli = ['/path/to/mathoid/cli.js', '-c', '/path/to/mathoid/config.yaml'];
// Raise MediaWiki's memory limit to 1.2G for mathoid.
$wgMaxShellMemory = 1228800;

If you run MediaWiki under system containing SELinux and you get Mathoid cli '/path/to/mathoid/cli.js' is not executable message from the error log, you can run

setsebool -P httpd_execmem 1
setsebool -P httpd_setrlimit 1

to make sure the Apache server allow to change system limits.

LaTeX

Mode: 'png' (pre-July 2015: MW_MATH_PNG)

Since MediaWiki 1.32, this mode will also require a Mathoid server to work. In older versions, it requires installing texvc and texvccheck, which may require the most setup work.

LaTeXML

Mode: 'latexml' (pre-July 2015: MW_MATH_LATEXML)

Uses the LaTeXML utility. The rendering is done via an online service (set with $wgLaTeXMLUrl, which has a default value).

No rendering

Mode: 'source', (pre-July 2015: MW_MATH_SOURCE)

This mode will forward the Latex input without rendering, presenting it in a <span> element, surrounded by $ :formula $.

Make sure to set $wgMathDisableTexFilter to 'always' (see below) if you only want the raw latex formula, else an error will appear due to the failed check for PNG depictions.

MathJax

  Figyelem: The client-side MathJax rendering mode is removed in MediaWiki 1.26. See Extension:SimpleMathJax for an alternative.

Lényeges konfigurációs beállítások listája

Setting name Default value Description
$wgMathValidModes array( 'png', 'source', 'mathml' ) Defines the mode allowed on the server.
$wgMathDisableTexFilter 'never' Option to disable the tex filter. If set to true any LaTeX expression is parsed this can be a potential security risk. If set to false only a subset of the TeX commands is allowed. See the wikipedia page Help:Math for details. Use "always" to disable this feature.
$wgMathFullRestbaseURL false The math extension gets the default config from the Visual Editor, if available. Details.

Nyomkövető kategóriák

A kiterjesztés több nyomkövető kategóriát is létrehoz, amivel meg lehet találni a hibákat és elavult funkciókat. A kategóriák pontos nevét MediaWiki-névtérbeli lapok határozzák meg.

MediaWiki-lap Alapértelmezés Leírás
MediaWiki:Math-tracking-category-error Category:Pages with math errors Olyan lapok, ahol a képlet szintaktikailag hibás, így nem dolgozható fel.
MediaWiki:Math-tracking-category-render-error Category:Pages with math render errors Olyan lapok, ahol feldolgozás során ideiglenes hiba akadályozta a képlet megjelenítését. Ezek a lapok normál esetben maguktól megjavulnak egy idő után.
MediaWiki:Math-tracking-category-texvc-deprecation Category:Pages that use a deprecated format of the math tags Olyan lapok, amik elavult texvc-szintaxist használnak (pl. $ % \and \or \part \ang \C \H \bold \Bbb\ \pagecolor). Ezeket a szabványosabb LaTeX-re kell cserélni (rendre \$ \% \land \lor \partial \angle \Complex \mathbb{H} \mathbf \mathbb (removed)). Lásd még: Extension:Math/Roadmap .
MediaWiki:Math-tracking-category-mhchem-deprecation Category:Pages that use a deprecated format of the chem tags

Deprecated chemical markup, see Extension:Math/Roadmap#Step 1 Part C: Manual fixing of mhchem syntax.

Tippek és trükkök

  • You can use the Firefox MathML copy addon to copy formulae to other applications such as Microsoft Word (video), or Google docs with the g(Math) plugin (video)
  • You can override the user preferred and default rendermode by adding the forcemathmode attribute to the <math> element. eg.. to force an image being rendered <math forcemathmode="png">...</math>.

Hibabejelentés

If something is wrong with the math extension you can report that at Phabricator. In addition you should check how your problem relates to the automated unit tests that are generated from the page CoverageTest.
