Extension:Math/pt-br

A extensão Math fornece suporte para renderização de fórmulas matemáticas on-wiki via texvc e outros backends. Uma visão geral do que pode ser feito atualmente com esta extensão está disponível na documentação da Wikipédia em inglês.

More information about installing and configuring this extension, including for older versions, can be found at.

Ver matemática
A extensão Math tenta fornecer a saída MathML, com retorno para imagens SVG ou PNG, respectivamente.

O suporte matemático básico funciona para todos os navegadores. No entanto, para um processamento ideal, pode ser necessária uma afinação específica:


 * Para Firefox ou outros browsers  Gecko, é necessário instalar a extensão Native MathML extension e math fonts. O suporte de acessibilidade é fornecido por  NVDA, ​​ VoiceOver ou  Orca. Além disso, o NVDA requer o plugin  MathPlayer para ler matemática.
 * For Safari or other WebKit browsers, you may also install math fonts and enable native MathML rendering by inserting some CSS rules into the custom style sheet of your browser preference.

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


 * For Chrome you must insert some CSS rules into the custom style sheet of your browser preference in order to get accessibility support via ChromeVox or visual rendering via the MathJax plugin.
 * Em algumas versões do Internet Explorer, é possível usar MathPlayer como uma tecnologia assistiva.

Instalação
You should additionally go to the page Special:MathStatus to see whether all of the components of the Math extension now work. Se isso não funcionar, crie uma tarefa em https://phabricator.wikimedia.org

Unfortunately, there is no well tested guide on installing and  to work with the Math extension, but there is at least a working draft. 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.:

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

A partir do MW 1.23 + você pode usar um servidor Mathoid que usa MathJax para converter a entrada texvc no lado do servidor para renderização MathML + SVG. Mathoid é o modo de renderização que vai ser usado no futuro Wikipedia. Para isso, as seguintes configurações são recomendadas:

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

Confira Mathoid para encontrar instruções sobre como executar seu próprio servidor Mathoid. Note that as of March 2017 this is likely to also require a server/installation (see ).

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:

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 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.

Tracking categories
The extension creates a number of tracking categories to detect errors and deprecated features. The exact name of the categories is determined by pages in the MediaWiki namespace.

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

Relatório de erros
Se algo está errado com a extensão de matemática você pode denunciar isso em Phabricator. Além disso, você deve verificar como seu problema se relaciona com os testes de unidade automatizada que são gerados a partir da página CoverageTest.
