Extension:Math/ja

Math拡張機能は、数式を表現するためのサポートを提供します. この拡張機能で現在できることの概要は、英語版ウィキペディアのドキュメントにあります.

古いバージョンを含め、この拡張機能のインストールと設定に関する詳細はにあります.

Viewing math
Math拡張機能は、MathML出力をSVGまたはPNG画像にそれぞれフォールバックして出力しようとします. 使用しているデバイスの機能に応じて、出力の種類が選択されます. Basic math support works for all browsers. However, for optimal rendering specific tuning may be needed:


 * Firefoxや他のGeckoを使用している他のブラウザでは、ネイティブMathML拡張機能と算術フォントをインストールする必要があります. アクセシビリティサポートは、NVDA、VoiceOverまたはOrcaによって提供されます.  Additionally, NVDA requires the MathPlayer plugin to read mathematics.
 * Safariやその他のWebKitを使用しているブラウザでは、あなたのブラウザー設定のカスタムスタイルシートに数式フォントをインストールし、ネイティブのMathMLレンダリングを有効にしていくつかのCSSルールを挿入することもできます.

アクセシビリティサポートはVoiceOverスクリーンリーダーで提供されますが、まだOrcaでは提供されていません.


 * Chromeでは、ChromeVoxやMathJax plugin経由の視覚的レンダリングを利用するには、ブラウザの設定のカスタムスタイルシートにいくつかのCSSルールを挿入する必要があります.
 * いくつかのバージョンのInternet Explorerでは、MathPlayerを支援技術として使用することができます.

インストール
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 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
モード: '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.

To use Mathoid, the following settings are recommended:

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 ).

LaTeX
モード: '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
モード: '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
モード: '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 $wgMathFullRestbaseURL 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
モード: 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.

Tips and tricks

 * 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)

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.
