Tareas abiertas · Reportar un bug 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. ## Viewing math The Math extension tries to deliver MathML output, with fallback to SVG or PNG images respectively. 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. ## Instalación See this thread for information on how to install this extension for MediaWiki 1.31 and later. • Si usas Vagrant, instala con vagrant roles enable math --provision === Instalación manual === • Descarga y extrae los archivos en el directorio «Math» dentro del directorio extensions/ existente. • Añade el siguiente código a tu LocalSettings.php (preferiblemente al final): wfLoadExtension( 'Math' ); // See below for installation requirements and configuration settings:  • Ejecuta el script de actualización, que creará automáticamente las tablas que necesita esta extensión en la base de datos. • To see math beyond a plain text output, follow instructions below for enabling various math output modes. • Listo – Navega a Special:Version en tu wiki para verificar que la apariencia se haya instalado correctamente. Para quienes usan MediaWiki 1.24 o versiones anteriores: Estas instrucciones describen la nueva forma de instalar extensiones usando wfLoadExtension(). Si necesitas instalar esta extensión en versiones anteriores (MediaWiki 1.24 y anteriores), debes usar lo siguiente en lugar de wfLoadExtension( 'Math' );: require_once "$IP/extensions/Math/Math.php";


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.:

$wgMathFullRestbaseURL = 'https://en.wikipedia.org/api/rest_';  See Mathoid for instructions on how to run your own Mathoid server. Note that as of March 2017 this is likely to also require a RESTbase server/installation (see task T154394). #### Mathoid's CLI interface To use Mathoid's CLI interface, which is possibly easier to set up and resulting in less permanent memory consumption, while degrading performance, the following settings are recommended: // Set MathML as default rendering option$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;


### LaTeX

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

This is the mode that requires the most setup work, since at least the texvc utility has to be installed for it to work, and ideally texvccheck as well. See Installing texvc for how to install both of these.

### LaTeXML

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

### MathJax

Mode: MW_MATH_MATHJAX

This mode uses the MathJax application for client-side rendering. It is now deprecated, and requires MediaWiki 1.25 or lower in order to run. See Client-side rendering with MathJax for how to use it.

## Lista de todas las opciones de configuración

Establecer el nombre Valor predeterminado Descripción
$wgMathValidModes array( 'png', 'source', 'mathml' ) Defines the mode allowed on the server.$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.

## Reporte de errores

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.
