La extensión Accesorios ofrece a los usuarios una forma de elegir "accesorios" basados en JavaScript o CSS que proporcionan otros usuarios de wiki.

Los accesorios están hechos con Snippets (fragmentos) de JavaScript o CSS ubicados en las páginas del espacio de nombres de MediaWiki. Cada accesorio se define mediante una línea en MediaWiki:Gadgets-definition, que proporciona un nombre y una descripción para el accesorio, y una lista de los snippets de JS y CSS que utiliza (consulte la sección Usos a continuación).

Since Gadgets reside in the MediaWiki namespace (the list defining the gadgets as well as the actual code snippets), only sysops (interface admins from 1.32) can edit the code. This is as it should be: only users especially trusted by the wiki community should be able to edit JavaScript code that is used by other users, since JavaScript can easily be used to hijack accounts or spy on people.

Installation

  • Descarga y extrae los archivos en un directorio denominado «Gadgets» dentro de la carpeta extensions/.
    Developers and code contributors should install the extension from Git instead, using:cd extensions/
    git clone https://gerrit.wikimedia.org/r/mediawiki/extensions/Gadgets
  • Añade el siguiente código en la parte final de tu archivo LocalSettings.php : 
    wfLoadExtension( 'Gadgets' );
  • Yes Hecho – Navega a Special:Version en el wiki para verificar que la extensión se haya instalado correctamente.

Usage

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

Once MediaWiki:Gadgets-definition is created with at least one valid gadget, a new "Gadgets" section will be shown on Special:Preferences for all users. Users can enable the gadgets they would like to use there. An overview of gadgets currently defined by MediaWiki:Gadgets-definition is also rendered on Special:Gadgets, along with helpful links to the relevant localisation and script/style pages for easy creation or editing. Statistics about gadget preferences are available at Special:GadgetUsage.

Definition format

Each line on the MediaWiki:Gadgets-definition page should start with a "*" (asterisk) character to define a gadget. The line takes the following format: 

* mygadget [options] | page names

The first field ("mygadget" in the example) is the gadget's internal name. The label for the preferences page comes from an interface message page (MediaWiki:Gadget-mygadget) where the proper name and a short description can be written, which also allows wikitext markup to be used.

The internal name must begin with a basic Latin letter ([A-Za-z]) and may be followed by any number of letters, digits ([0-9]), hyphens (-), underscores (_), and periods (.). The reason for this limitation is that the internal name must be valid as the name of an HTML form name, as MediaWiki interface message key, and as ResourceLoader module name.

Options format: 

[ResourceLoader | option1 | option2 | ... optionN]

The ResourceLoader flag is required unless the gadget contains only styles. Options that are "flags" only need to have their name written to be turned on. Options that need a value are followed by an equals sign and a comma-separated list of values. All whitespace is optional and may be omitted. 

[ResourceLoader | myflag | mykey = value1, value2, value3 ]

Examples: 

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

or 

 * mygadget[ResourceLoader|package]| mygadget.js | mygadget-Foo.js | mygadget-data.json | mygadget.css

or 

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

Using Gadget Definition Namespace

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 are defined on pages in the Gadget definition namespace when $wgGadgetsRepoClass is set to 'GadgetDefinitionNamespaceRepo'.

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

Creation of the Gadget definition:mygadget page and putting in it the below JSON code have the same effect as mygadget[ ResourceLoader | rights=foo, bar ] | mygadget.js | mygadget.css. 

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

In above example, the Gadget:Mygadget.js and the Gadget:mygadget.css are used.

Options

Name Parameters Description Since
ResourceLoader None Marks gadget's scripts as compatible with ResourceLoader . 1.17 (r76527)
dependencies Comma-separated module names These modules will be loaded before the scripts of this gadget execute. See list of default modules. 1.17 (r76639)
rights Comma-separated privilege names Make the gadget available (and visible in preferences) only to users who have the specified privileges. 1.18 (r85268)
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). Note that you need to add both: hidden | default to load a module for all users.
  • 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, task T199478).
Use of skins should be a last resort, and should be restricted to specialized code which relies on DOM manipulated which is used in the absence of non-standardized APIs that are not served by the methods listed on ResourceLoader/Core modules.
 1.19 (r100509)
actions Comma-separated action names Make the gadget available only on the specified page actions. E.g. actions = edit, history to load a gadget only while editing and on history pages.
Specifying edit action will also load it on action=submit. Invalid actions effectively disable the gadget since it can't be run anywhere.
 1.38 (gerrit:747112)
namespaces Comma-separated namespace numbers Make the gadget available only on the specified namespaces. E.g. namespaces = 0, 2 to load a gadget only in mainspace and user namespace. 1.41 (gerrit:624517)
contentModels Comma-separated content models Make the gadget available on pages with the given content models. E.g. contentModels = wikitext to load a gadget only on wikitext pages. 1.41 (gerrit:922062)
default None Enable the gadget by default for everyone (including IPs). Registered users can still disable it in their preferences. 1.18 (r85902)
package None Mark this gadget as packaged. In this mode, only the first JavaScript page will be executed. Other pages can be imported by using the require() function. This mode also enables use of JSON pages, which cannot be included otherwise. 1.38
targets desktop, mobile or desktop,mobile(default) (eliminado en 1.42.0-wmf.16) Set the ResourceLoader target(s) for the gadget.
Do not use targets, instead use skins where absolutely necessary.
 1.21 (gerrit:60954)
type styles (default for CSS-only gadgets) or general (default otherwise) 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.
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 gadget names These CSS-only gadgets will be loaded together with this gadget. These gadgets will be loaded before any dependencies, and their styles will be applied even if JavaScript is disabled. For details, see ResourceLoader/Migration guide (users)#Gadget peers. 1.29.0
supportsUrlLoad None | true | false Make the gadget available to be loaded with the ?withgadget URL query parameter. 1.38
requiresES6 None (eliminado en 1.42.0-wmf.13) Allow use of ES6 syntax (ES2015) in the gadget. Enabling this means server-side syntax validation is skipped for the gadget. Any ES6-requiring gadgets are loaded together in a single web request, which isolates failures due to invalid or unsupported syntax to those gadgets only, without affecting other gadgets and MediaWiki software features. It is recommended to use a tool like ESLint to ensure only valid ES6 syntax is used. Conflicts with default. 1.40.0-wmf.7 (gerrit:758086)
top None (eliminado en 1.29) 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. 1.22 (gerrit:75506)

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


User rights

This extension adds two new user rights, gadgets-edit and gadgets-definition-edit, which by default aren't given to any group.

You can add the following in your LocalSettings.php to provide the appropriate permissions for users who are within the interface-admin group. Editing pages in the Gadget namespace requires the gadgets-edit right and editing pages in the Gadget definition namespace requires the gadgets-definition-edit right. 

$wgGroupPermissions['interface-admin']['gadgets-edit'] = true;
$wgGroupPermissions['interface-admin']['gadgets-definition-edit'] = true;

Pages

The remaining fields on the definition line refer to the JavaScript, CSS or JSON source pages that makes up the gadget module. These are stored in the MediaWiki namespace as interface messages (MediaWiki:Gadget-mygadget.js and MediaWiki:Gadget-mygadget.css in the example). The page names must end with ".css", ".js", or ".json" respectively.

A gadget can use any number of source pages, e.g: 

 * frobinator[ResourceLoader]|frob.js|frob.css|pretty.css
 * l33t[ResourceLoader]|l33t.js
 * foobar[ResourceLoader|package]|foo.js|bar.js|foobar-data.json

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>...‎</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.

Sections

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.
