Extension:Math/advancedSettings/ja

数式拡張機能はtexvcその他のバックエンドを利用し、数式のレンダリングをサポートします. この拡張機能で現在、何ができるかについては数式の表示にまとめてあります.

texvc のインストール
サーバ側で LaTeX から PNG に変換するには、以下のステップに従います.

texvc について
TeXバリデーター兼コンバーターtexvc は数式を入力するとフォーマットし、HTMLやMathML、PNG画像として出力します. 入力データは安全のため解析して精査します.

シェルアクセスが制限された共有ホスト
On a shared host with limited command line access, (e.g. under jailshell) compiling with all the dependencies won't be possible. As a workaround compiling texvc will have to be done offline. Use  to identify the OS of the shared host, and install the same offline. This can be done via a USB boot drive, live CD, virtual machine on a desktop PC or whichever you prefer. Then for example in Ubuntu, all dependencies can be installed using:

Get the Math extension and make texvc etc.:

Upload the  archive to the host and extract the required files  into the $IP/extensions/Math folder.

To test texvc is working (see texvc usage), e.g.:

Linux の配布によってはMediaWiki Mathパッケージにtexvcとtexvccheckが同梱されています.

クライアント側で MathJax を使用して変換
From 1.19/1.20, the Math extension supports rendering via MathJax, a client-side JavaScript library for parsing latex or mathml code and producing in-browser representation using the browser's native support for HTML+CSS, or MathML, or SVG.

This can render math expressions more sharply (using subpixel antialiasing) and larger (scaling up for zoomed view, printing, or high-resolution screens).

Set $wgUseMathJax to enable MathJax rendering mode; it is still somewhat experimental. Users will have a check box on their preferences that will enable MathJax, or set MathJax to the default mode as shown below.


 * 設定 (MW 1.19 - 1.22)


 * 設定 (MW 1.23 - 1.25)

See also How to modify the MathJax contextual menu.


 * Forcing MathJax as the only rendering option (MW 1.23+)

If you have a wiki where MathJax is the only available rendering mode, and wish to force it to be enabled, add the following to LocalSettings.php instead of the above:

This will switch on MathJax by default for all anonymous users and those without preferences saved for the Math extension. Note that if registered users had an alternate rendering mode selected, it will be necessary for them to open Preferences > Appearance and click Save for the new forced setting to take effect. Articles should advise users about the requirement for JavaScript to be enabled in order to see formulae (e.g. through a template for articles including TeX formulae).

サーバ側で MathJax を使用して変換
Beginning from MW 1.23+ you can use a Mathoid server that uses MathJax to convert texvc input on the server side to MathML+SVG rendering. Mathoid is the rendering mode that is going to be used on future Wikipedia. For that the following settings are recommended:

Check out Mathoid to find instructions how to run your own Mathoid server. After enabling the MathML rendering mode you have to run the database update script again to create the required table.

サーバ側で LaTeXML を使用して変換
A convenient option to render LaTeX is to use the LaTeXML web service. This service converts LaTeX to high quality MathML.


 * Settings (MW 1.22) most or all of the 1.23+ settings also work


 * 設定 (MW 1.23 以降)

A short guide to install LaTeXML on your own server can be found here: Install LaTeXML

After enabling the LaTeXML rendering mode you have to run the database update script again to create the required table.

サーバ側で LaTeX を使用して変換
To use your local webserver to convert the texvc input to PNG images via a local LaTeX installation and OCAML based translation from texvc to LaTeX you have to install texvc; see above for how to do that.

Settings in  should refer to the   rendering engine:

を呼び出した後、LocalSettings.phpに以下の変数を定義します.

CSS で MathML に SVG フォールバックモードを設定
MathML は既定ではアクセシビリティのツールからしか見えない設定です. しかしながら以下のスタイルを指定し、強制的にレンダリングを視覚化できます.

すると MathML 数式の書式も自由に変更可能で、たとえば数式用フォントの設定ができます.
