Manual:How to make a MediaWiki skin/ja

外装 (スキン) を作成することは、MediaWiki の内部構造に慣れ親しみ、ウィキメディア運動への貢献を開始するための素晴らしい方法です. CSS、JavaScript、JSON などのフロントエンド技術に精通している場合は、MediaWiki の外装を作成できます. PHP を知っている必要はありませんが、高度なことをしたい場合には役立つかもしれません.

必須ではありませんが、Mustache テンプレートと LESS CSS に精通していると役立ちます. This tutorial assumes that you have installed a working version of MediaWiki, and are running the current development release, if not, it is recommended you do that first.

If you having an existing skin using the PHP BaseTemplate, this guide is not for you. Please see Manual:How to make a MediaWiki skin/Migrating SkinTemplate based skins to SkinMustache instead.

始めてみよう
最初の外装を作成し始めるには、2 つの選択肢をお勧めします.

Option 1 - Fork Example skin
The Example skin https://github.com/wikimedia/mediawiki-skins-Example provides the bare bones implementation of a skin. Clone the repository in your skins folder making sure the folder is called "Example" and add the following to your LocalSettings.php:

If all has gone to plan your skin should be available on the Special:Preferences page of your wiki.

Option 2 - Use the skins lab
The skins lab tool allows you to setup a skin with basic CSS and templates. Once you feel comfortable, you can click "download as ZIP" which will compile the necessary boiler plate for your skin. できあがったリポジトリが簡単に操作できるといいですね. When you have downloaded the ZIP place it in your MediaWiki skins folder and update LocalSettings.php with the following:

If all has gone to plan your skin should be available on the Special:Preferences page of your wiki.

Let people know!
Making a skin will be more fun with other people and much easier too! Once you have got something usable, please consider publishing it to GitHub or. Once the code is publicly available, you should create a skin page (make sure you change the title!) to let people know you are open for collaboration!

Setting up a wiki page has many other benefits. You'll be able to handle bug reports in Phabricator or GitHub issues and receive patches from other volunteers in the MediaWiki community. Somebody should also be able to help you setup translation.

Mustache
In 1.35 we added support for Mustache in skins. We found using Mustache to be very helpful in the development of the Skin:Minerva and Skin:Vector skins as it allows you to separate data from presentation. Mustache partials can be used to reuse templates. To use a partial Partial.mustache in MediaWiki, simply add them to the folder you are working in and reference them using in the master template `skin.mustache`.

The data sent to Mustache templates is relatively flexible. If something is missing, you can use PHP to add data by extending the SkinMustache::getTemplateData function.

The SkinJson skin can be added to a MediaWiki development instance, to inspect the data available to skins. Note that arrays are prefixed "array-", booleans are prefixed with "is-" and objects are prefixed "data-" to help you conceptualize the data you are working with.

Making your skin translateable (i18n)
In skin.json under ValidSkinNames, you can use the `messages` option to define translateable message keys. These keys should correspond to entries inside the i18n/en.json folder. Once registered for the skin, these will be available in your template with a prefix "msg-".

For example in the example below, the message "sitetitle" can be rendered in a Mustache template using

See Localisation for more information on why this is important.

Rnedering template partials
Template partials can be used to render different parts of the skin. In the following example, the skin renders the contents of the templates in the 3 files with the filenames Logo.mustache, Content.mustache and Footer.mustache.

Logo.mustache
Following code block is being used to show the site logo in the Example skin and you will also see the same if you create the skin from the SkinLabs.

From the code block mentioned above, the following line is responsible to show the logo `icon`:

This line assumes that, there is a key  in the array $wgLogos. So in your LocalSettings.php file, if there is a line similar as, then the logo/ icon image will be displayed. The default Mediawiki  exports a   key in the   array.

So to show the logo you need to update the LocalSettings.php and add a key.

Note: If you want to change the logo do not just replace the default logo with a new one in the  path. Because it will be changed to default, when you update the MediaWiki. The recommended way to change the logo is to add a new logo image file and add that path to the LocalSettings.php.

既定
A skin at minimum requires a single style ResourceLoader module. It will look a bit like this:

The features key allows you to use useful boiler plate defaults for a variety of things including i18n and normalize which are documented in the MediaWiki core php documentation. Features can be a list of keys (opt-in policy) or in 1.36 an object (opt-out policy). If you are not sure, please omit the features key to use the recommended defaults.

CSS / LESS
The skin.json is a manifest of all the assets your skin uses. Under the `ResourceModules` key you should find the style module for your skin listed under `skins.example`. Here, under the "styles" key you can add LESS or CSS files. They will be loaded in the order they are listed. With LESS you can use @import statements in the same folder. More information about what's possible can be found in ResourceLoader/Developing_with_ResourceLoader.

When using images you should be able to use relative URIs to access the image assets.

Images
You can extend Manual:$wgLogos with any data you choose to. This will allow site admins to configure images as they choose, but you must always conditionally render them.

In cases where images must be hardcoded for some reason., and cannot use a CSS background-image, or wgLogos for any reason you will need to extend the data sent to the template

JavaScript
JavaScript code in skins, runs in an environment where you can rely on the `mw` and `jQuery` objects having been loaded. We recommend using ResourceLoader/Package_files which will allow you to require file assets.

For information on the available API and libraries see core JS documentation.

More advanced
More advanced information will provided on an as requested basis. Please ask a question on the talk page to accelerate the addition of documentation!

i18n
Messages defined in i18n/en.json can be passed directly to your Mustache template by inclusion in skin.json. Note, that you can use any messages defined inside MediaWiki core.

Extending data
If you need to add additional data for rendering inside your skin's template that cannot be served by messages (as in the i18n section) e.g. raw HTML or complex data structures you can extend the SkinMustache::getTemplateData method.

Default styling via the ResourceLoaderSkinModule class
All skins should define a single style module with the class ResourceLoaderSkinModule. The module defines various default styles to take care of MediaWiki internals. If you want, you can disable these features and provide your own styles. Define features as an empty object to tie yourself into the recommended MediaWiki defaults. A list of support features is provided in our docs.

Example ResourceLoaderSkinModule that disables the logo feature but enables several others:

Integrating with other extensions
Extensions should integrate with you, not the other way round! Try to forget about extensions when writing your skin. User:Jdlrobson/Skins for extension developers is provided for extension developers to ensure they get the best compatibility. The starter templates in Manual:How_to_make_a_MediaWiki_skin will render all possible UI elements. If you omit certain pieces of data you may break support with extensions.

For certain extensions you may want to tweak the styles of the default UI elements, notably Extension:Echo. To do this you will need to read Manual:$wgResourceModuleSkinStyles.

Changing menu content
The composition of menus can be changed by using hooks. For example in Vector, the SkinTemplateNavigation hook is used to relocate the watch star icon. When doing this, remember to check the skin being operated on, to avoid side effects in other skins.

I want to change elements in the head of the HTML page
Skin developers should not concern themselves with modifying anything in the HEAD of a document. Modifications of the HEAD are better served via extensions and configuration inside LocalSettings.php. For any questions please use the

I am writing an extension that needs to style itself differently depending on the skin
Extensions can make use of skin styles to ship skin-specific styles using the skinStyles key. See Manual:$wgResourceModuleSkinStyles.

Building skins for 1.35
In 1.35 support for building skins was not as straightforward as in 1.36. If you wish to build a skin for 1.35, using template data provided in 1.36, you will need to extend the SkinMustache  PHP class. A polyfill for the Example skin is provided.

Your feedback is important
If something is not easy, we'd like to make it easier, so your feedback is important. If you run into problems, then please file a bug report in the mediawiki core skin architecture project in Phabricator, and we'll try and find an elegant solution.

Please feel free to ask a question on the talk page. There is no such thing as a stupid question.
