小工具擴充功能提供了一種方式,能讓使用者選擇其他wiki使用者提供基於JavaScript和CSS的小工具

小工具由位於MediaWiki命名空間頁面中的JavaScript和CSSsnippets 組成。 每個小工具由MediaWiki:Gadgets-definition中的一行所定義,並提供了小工具的名稱及描述,以及JS和CSS程式碼片段的列表(參見底下的用法段落)。

由於小工具位於MediaWiki命名空間(定義小工具的列表和實際的程式碼判斷皆是),因此只有管理員(自1.32起為介面管理員)能編輯程式碼。 這是因為:只有受到wiki社群高度信任的使用者才能編輯JavaScript程式碼,因為它被其他使用者所用,且JavaScript能輕鬆地劫持帳號和監視他人。

安装

  • 下载文件,并将其放置在您extensions/文件夹中的Gadgets目录内。
  • 将下列代码放置在您的LocalSettings.php的底部:
    wfLoadExtension( 'Gadgets' );
    
  •   完成 – 在您的wiki上导航至Special:Version,以验证扩展已成功安装。

致使用MediaWiki 1.24或更早版本的用户:

上面的说明介绍的是安装此扩展的新方法,它使用wfLoadExtension()。 如果您需要在早期版本(MediaWiki 1.24和更早版本)中安装此扩展,而不是wfLoadExtension( 'Gadgets' );,您需要使用:

require_once "$IP/extensions/Gadgets/Gadgets.php";

用法

 
Selection of some gadgets at the user preferences in de.wikipedia

There are two ways to define gadgets depending on the $wgGadgetsRepoClass. If It is 'MediaWikiGadgetsDefinitionRepo' (the default value), the list of available gadgets is defined on MediaWiki:Gadgets-definition. In an alternative way, Gadget definitions defined on pages in the Gadget definition namespace when $wgGadgetsRepoClass is set to 'GadgetDefinitionNamespaceRepo'.

  小心: Migration of the existing gadget definitions is not yet supported, so you will lose previously defined gadgets after changing this option.

Once created with at least one valid gadget, gadgets defined there show up in the "Gadgets" section of Special:Preferences, so users can pick the gadgets they would like to use. An overview of the gadgets defined by MediaWiki:Gadgets-definition is also shown on Special:Gadgets, along with links to the respective system messages, for easy editing. Statistics for non-default gadget usage can be seen at Special:GadgetUsage.

格式

使用MediaWiki Gadgets Definition

Each line in MediaWiki:Gadgets-definition that starts with one or more "*" (asterisks) characters defines a gadget; it must have the following form:

 * gadget_name [options (can be omitted)] | page names

The first field ("gadget_name" in the example) is the gadget's internal name, and references a system message (MediaWiki:Gadget-gadget_name in the example) that contains a short description of the gadget, using wiki syntax.

The internal name is used as part of the name of a form field and must follow the rules defined for NAME attribute values. This means it must begin with a basic Latin letter ([A-Za-z]) and may be followed by any number of letters, digits ([0-9]), hyphens (-), underscores (_), colons (:), and periods (.).

Options format:

[option1 | option2 | ... optionN]

whitespace can be omitted. A single option can either consist of a single option name (in this case it is a flag option), or contain a comma-separated list of values:

option = value1, value2, value3

Examples:

 * mygadget|mygadget.js|mygadget.css

or

 * mygadget[ResourceLoader]|mygadget.js|mygadget.css

or

* mygadget[rights=foo,bar]|mygadget.js|mygadget.css

or

* mygadget[ ResourceLoader | rights=foo, bar ] | mygadget.js | mygadget.css
使用小工具定義命名空間

建立Gadget definition:mygadget頁面並放入以下的JSON程式碼與mygadget[ ResourceLoader | rights=foo, bar ] | mygadget.js | mygadget.css有相同的效果。

{
	"settings": {
		"rights": [ "foo", "bar" ],
		"default": false,
		"hidden": false,
		"skins": [],
		"category": ""
	},
	"module": {
		"scripts": [ "mygadget.js" ],
		"styles": [ "mygadget.css" ],
		"peers": [],
		"dependencies": [],
		"messages": [],
		"type": ""
	}
}

In above example, the Gadget:Mygadget.js and the Gadget:mygadget.css are used. And remember the ResourceLoader option is always true in the gadget definition namespace.  注意:

选项

名称 參數 描述 以来
ResourceLoader None Marks gadget's scripts as compatible with ResourceLoader. ?
dependencies Comma-separated module names See list of default modules. Note that this option has no effect if current gadget has no ResourceLoader-compatible resources (i.e. no styles and scripts not marked as compatible). ?
rights Comma-separated privilege names Make the gadget available (and visible in preferences) only to users who have the specified privileges. ?
hidden None Hide the gadget from the Preferences page. This can be used in two ways:
  • Enable a gadget by default without ability to disable (as modular alternative to Common.js).
  • Gadgets that are not meant for end-users, but rather are meant to be loaded by other gadgets. For example to allow two gadgets to re-use the same internal code, or to register the "core" part of a gadget that only loads on certain pages.
1.28
skins Comma-separated skin names Make the gadget available (and visible in preferences) only to users who use the specified skins. Before MediaWiki 1.32 it was taking into consideration the skin set in preferences for the user, not the current displayed one (like when adding ?useskin=monobook in the URL, 任务T199478) ?
default None Enable the gadget by default for everyone (including IPs). Registered users can still disable it in their preferences. 1.18
targets desktop (default), mobile or desktop,mobile Set the RL target(s) for the gadget. ?
type styles or general Use styles for modules that only modify styling for elements already on the page (e.g. when customizing the skin, layout, or article content). It will cause the CSS files of the module to be included from the page HTML instead of being loaded via JavaScript. For details, see ResourceLoader/Migration guide (users)#Gadget type.

Note: Using styles will not load in any specified JavaScript files. For gadgets that modify styling for elements through both JavaScript and CSS, two individual gadget definitions are required.

1.28
peers Comma-separated module names Require CSS-only gadgets (which usually would be hidden). These gadgets will be loaded sooner than by dependencies, and will be loaded even if JavaScript is disabled. For details, see ResourceLoader/Migration guide (users)#Gadget peers. 1.29.0-wmf.11
(pre-release)
top None (在1.29版本中已移除) Makes the gadget to be top-loaded. This should be used sparingly, but may be needed for some initialization stuff like registering plugins with VisualEditor. ?

You can specify extra dependencies for your gadgets, for example:

* mygadget[ResourceLoader|dependencies=jquery.ui, jquery.effects.clip]|mygadget.js|mygadget.css

Here, we ask ResourceLoader to load modules jquery.ui and jquery.effects.clip with mygadget. Note that gadgets can't depend on scripts from pages, static files or external URLs, only on modules already registered in ResourceLoader. To make a script from a page depend on another script from a page, each should be a gadget which registers itself as a module in ResourceLoader, then they can be made to have dependencies using the following syntax:

* childgadget[ResourceLoader|dependencies=ext.gadget.parentgadget]|childgadget.js

To enable a gadget by default, use "default":

* mygadget[ResourceLoader|default|dependencies=mediawiki.util]|mygadget.js|mygadget.css

To make the gadget available only to users with appropriate permissions, set the rights option. For example,

* ImprovedDeletion [rights=delete] | ImprovedDeletion.js

makes the gadget available only to users who can actually delete pages. Note that restrictions are based on permissions, not user groups like administrators or bureaucrats. Here are some real examples:

* modrollback[ResourceLoader|rights=rollback]|modrollback.js
* UTCLiveClock[ResourceLoader|rights=purge]|UTCLiveClock.js
* Ajax_sysop[ResourceLoader|rights=patrol,rollback,markbotedits,delete]|Ajax_sysop.js

ResourceLoader support

Each gadget's CSS is always loaded via the ResourceLoader. However, older JavaScript is often incompatible with RL, so every gadget must be explicitly marked as compatible in order to have its scripts loaded by RL. Otherwise, plain old <script src="/w/index.php?title=MediaWiki:Gadget-gadget_name.js&action=raw&ctype=text/javascript"> will be used.

Every gadget that at least partially uses ResourceLoader (that is, that has styles or compatible scripts) has its own RL module. The modules are named ext.gadget.<gadget name>.

页面

The remaining fields on the line refer to the JavaScript or CSS code that makes up the gadget, contained in system messages (MediaWiki:Gadget-mygadget.js and MediaWiki:Gadget-mygadget.css in the example); the names of those messages must end with ".js" or ".css", respectively. A gadget can use any number of code messages, specifically, common code can be put into a code message used by several gadgets, in addition to their own specific code, e.g:

 * frobinator|commonStuff.js|frob.js|frob.css|pretty.css
 * l33t|commonStuff.js|tools.js|l33t.js

Please note that if your code contains strings that could be interpreted as wiki syntax (e.g. the signature code ~~~~), you may want to enclose your code into <nowiki> and </nowiki> and put these tags in JavaScript or CSS comments so they're not interpreted when actually used. See the first and last lines of MediaWiki:Gadget-externalsearch-bar.js for an example.

章節

The list of gadgets in MediaWiki:Gadgets-definition can be broken into sections using lines that start and end with two or more "=" (equals) characters, enclosing the name of a system message that defines the section's name - for example:

 == interface-gadgets ==

This would define a new section, with the title defined on the page MediaWiki:Gadget-section-interface-gadgets.
