A Math kiterjesztés matematikai képletek megjelenítésére ad támogatást.

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

A jelenleg a kiterjesztéssel elvégezhető dolgok elérhetők itt: Extension:Math/Szintaxis.

Telepítés

This extension comes with MediaWiki 1.38 and above. így nem kell újra letöltened. Az útmutató egyéb utasításait azonban továbbra is követned kell.
  • Töltsd le a kiterjesztés fájljait, és mentsd el az extensions/ mappán belüli Math könyvtárba.
    Developers and code contributors should install the extension from Git instead, using:cd extensions/
    git clone https://gerrit.wikimedia.org/r/mediawiki/extensions/Math
  • Add hozzá az alábbi kódot a LocalSettings.php fájlod aljára: 
    wfLoadExtension( 'Math' );
  • If you are using MediaWiki version before 1.42, run the update.php script to create the necessary database tables. This is no longer necessary if you are installing Math in MediaWiki 1.42+.
  • To see math beyond a plain text output, follow instructions below for enabling various math output modes.
  • If you have problems for represent formulas when trying to use RESTBase, you can try using the following patch
  •   Kész – A Special:Version oldalon ellenőrizheted, hogy a kiterjesztés ténylegesen feltelepült-e.


Vagrant-telepítés:

  • Vagrant használata esetén telepítsd a vagrant roles enable math --provision paranccsal

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.

Usage

Once installed, you write formulas using TeX markup syntax inside the ‎<math> tag. For example: 

<math>E=mc^2</math>

Renders as:

E=mc2


Képletek megjelenítése

The type of output depends on the software that you use to read the page. If it can, the Math extension outputs MathML. Otherwise, it outputs images in SVG (converting characters to <path> elements) or PNG. Basic math support works for all browsers. But, for best results, you might need to change your settings:

Konfigurációs beállítások

Setting name Default value Description
$wgMathValidModes [ '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.
$wgMathPreferRestbaseURL true Whether to allow using of internal RESTBase path instead of $wgMathFullRestbaseURL and $wgVisualEditorFullRestbaseURL. Set false if you want to use external RESTBase in any case.

Matematikai kimeneti módok

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

Mód: 'mathml'

  Figyelem: Mathoid is no longer actively developed in favor of Native MathML mode. It will eventually be discontinued.

You can use Mathoid, an application that uses MathJax on the server side to convert texvc input to MathML+SVG rendering. Mathoid is currently the Math rendering mode used on Wikipedia.

Mathoid szolgáltatásként

"Mathoid as a service" is the recommended approach for the Math extension, and the default one. If you do not add any additional settings to LocalSettings.php, Math will use the Beta cluster's Mathoid and RESTBase services to do all math formula rendering. The default settings are: 

// Set MathML as default rendering option
$wgDefaultUserOptions['math'] = 'mathml';
$wgMathUseInternalRestbasePath = false;
$wgMathFullRestbaseURL = 'https://wikimedia.org/api/rest_';
$wgMathMathMLUrl = 'https://mathoid-beta.wmflabs.org';
  Figyelem: Wikimedia plans to discontinue RESTBase services including the Mathoid endpoint used by Math extension by default, though there is no specific EOL date yet. For sites using newer MediaWiki versions, Native MathML mode is recommended instead.

You can modify these settings to use different Mathoid and RESTBase services, potentially including your own.

Mathoid's CLI interface

You can instead run Mathoid as a command-line utility on the local server. To use this approach, 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 in a system containing SELinux and you get the message Mathoid cli '/path/to/mathoid/cli.js' is not executable in the error log, you can run the following to make sure that the Apache server allows to change system limits: 

setsebool -P httpd_execmem 1
setsebool -P httpd_setrlimit 1

LaTeX

MediaWiki-verzió:
≤ 1.39

Mode: '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'

Uses the LaTeXML utility. The rendering is done via an online service (set with $wgLaTeXMLUrl, which has a default value of https://latexml.formulasearchengine.com/convert).

Native MathML

MediaWiki-verzió:
≥ 1.40

Mode: 'native'

This mode will generate MathML from LaTeX via PHP without Mathoid. Note this mode does not have image fallback, so formulas will only be displayed correctly if the browser supports MathML. Firefox and Safari introduced MathML support early (2006 and 2008), but support in Chromium-based browsers is a much more recent addition (Chrome 109, released in 2023).

MathJax

MediaWiki-verzió:
≥ 1.42

Mode: 'mathjax'

This mode works the same as Native MathML mode (generating MathML from LaTeX via PHP), but it will use MathJax 3 to render MathML. Therefore it will work for browsers that do not have MathML support, with the overhead of loading MathJax library (bundled in Math extension) on page views.

  Figyelem: Previously, a MathJax mode based on MathJax 2 is provided in MediaWiki 1.19-1.25. To use MathJax to render formulas in MediaWiki 1.26-1.41, see Extension:SimpleMathJax .

No rendering

Mode: '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.

Nyomkövető kategóriák

A kiterjesztés több nyomkövető kategóriát is létrehoz, amivel meg lehet találni a hibákat és elavult funkciókat. Their message keys begin with math-. Administrators may change a tracking category's name in a wiki by editing the message's value in that wiki's MediaWiki namespace. Special:TrackingCategories shows each tracking category's name, message key, and description.

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 .

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. e.g. to force an image being rendered <math forcemathmode="png">...</math>.
  • All images of rendered formula are stored in a cache and not automatically recreated if the page is viewed or edited. To force the re-rendering of all formulas of a page, purge using the ?action=purge&mathpurge=true action. For example the URL https://en.wikipedia.org/w/index.php?title=Integral&action=purge&mathpurge=true will force re-rendering of the w:Integral article. Afterwards you need to bypass your browser cache so that the new created images of the formulas are actually downloaded.

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.
