විකිපීඩියා:User scripts/Guide

විකිපීඩියා වෙතින්

To write user scripts, you'll have to learn at least some of the programming language that they are written in: JavaScript.

Try these links:

Also, it would definitely help if you tried using one of our scripts and got it working. The rest of this tutorial assumes you know where the various things are (all explained at Wikipedia:User scripts#How do you install user scripts?).

Forking an existing script[සංස්කරණය]

Starting out, it may be easier to modify an existing script to do what you want, rather than create a new script from scratch. This is called "forking". To do this, copy the script to a subpage, ending in ".js",[n. 1] of your user page. Then, install the new page like a normal user script.

Writing a script from scratch[සංස්කරණය]

While you can write a script directly in your common.js page or skin.js (such as vector.js) page, it is usually better to create a new subpage for it in the form YourUserName/title.js, where title is the name of your script. That keeps your main js pages from getting cluttered, which is helpful when you have multiple scripts installed. You will also want to install the new user script.

Hello world[සංස්කරණය]

To make a Hello world program, insert this code into your User:YourUserName/common.js file.


Next, create the page User:YourUserName/hello-world.js, and insert this code.

$('#bodyContent').prepend('<p>Hello world!</p>');

This will write "Hello world!" on every page, below the title, until you remove the code. This uses JQuery, although you could also write this in pure JavaScript. #bodyContent is a selector that lets us reference the HTML element we want. prepend inserts HTML code as a child of the #bodyContent element, at the beginning.

Your first script[සංස්කරණය]

We will be writing an independent module by modifying your js, so you may want to get our module template. For the purpose of this tutorial, we will write a simple version of the Quick wikify module, which adds the {{Wikify}} maintenance template to articles. To begin, change MODULE_NAME in the module template to "Qwikify". Your template should look like this:

// Qwikify
$(document).ready( function () {
} );

In MODULE_CODE, we want to add the "Wikify" tab, so we will use the addPortletLink function (which requires "mediawiki.util" module). Replace MODULE_CODE with a call to this function. Then we'll bind an event handler so that when this link is clicked, we will call another function named doQwikify() that will actually execute the code. The name is what is shown on the tab, so set that to "Wikify". Most tabs have an id of "ca-(their name)", so set the id to "ca-wikify". The title (also known as mouseover or rollover text) should be something like "Mark for wikification". Lastly, we use jQuery's .click() to listen for clicks on this link, and when that happens execute a function. After we call doQwikify(), it says event.preventDefault(). Since we clicked on a link, we need to tell the browser to prevent its default behavior (which is going to a the url, '#'). We want the page to stay right where it's at, so to prevent the browser from following the link, we prevent that and do our own custom action.

Altogether, your new function should look like this:

// Make sure the utilities module is loaded (will only load if not already)
mw.loader.using( 'mediawiki.util', function () {

    // Wait for the page to be parsed
    $( document ).ready( function () { 

        //see below "Portlets" subsection
        var link = mw.util.addPortletLink( 'p-cactions', '#', 'Wikify', 'ca-wikify', 'Mark for wikification'); 
        $( link ).click( function ( event ) {

        } );
    } );
} );

Now, we must write our actual doQwikify() function. It will edit the edit box, so we need to get the name of that and its form. Viewing the source of the page shows that the form is named editform and the textbox is named wpTextbox1, meaning that the actual text is document.editform.wpTextbox1.value. To add {{wikify}} (and two new lines), we simply do:

document.editform.wpTextbox1.value = "{" + "{wikify}}\n\n" + document.editform.wpTextbox1.value;

(We separate the two "{" brackets in the front of the wikify template so it doesn't get expanded when we write this code on the wiki.)

Finally, we want to submit the form for the user. Luckily, JavaScript has a built-in function just for this named submit(). To submit our editing form, use document.editform.submit(). Your code should now look something like this:

function doQwikify() {
    document.editform.wpTextbox1.value = "{" + "{wikify}}\n\n" + document.editform.wpTextbox1.value;

And that's it! Save the common.js and then do a hard refresh. Go and edit a page such as the Sandbox, and see what happens![1]

On load/document ready function[සංස්කරණය]

The personal "user" module (built from /common.js, /common.css and optionally the skin-specific files for the current skin) and gadgets are loaded on all pages. Most scripts will want to manipulate elements on the page; to do so the page needs to be ready (which may not be the case at the time the modules are loaded). We can defer execution of code by using a special function. Most commonly .ready() from jQuery.

// Define our main function
function myScript() {
  // ... code ...

// Schedule it to run after the HTML page is parsed
$( document ).ready( myScript );

// This shorthand is also valid
jQuery( myScript );

Since the function is called only once, many users prefer to shorten this code with an anonymous function:

$( document ).ready( function () {
  // ... code ...
} );

// Or
jQuery( function () {
  // ... code ...
} );

Note: $ and jQuery are the same object; choosing between them is purely a matter of opinion.

Many scripts use this function simply to add some script interface, such as a link in a portlet. Then the main part of the code is executed after the user clicks on that link.

Built-in scripts[සංස්කරණය]

All Wikipedia pages include some built-in MediaWiki JavaScript code, with variables and functions that can be used in user scripts. The specific code depends on the viewed page and current users, for more details see Wikipedia:Catalogue of CSS classes#Stylesheets and JavaScript.

Of most interest are:

Development and testing[සංස්කරණය]

The following development environments can be used to develop and test your script.


  • Using the preview button: You can edit your script directly on your /common.js page, then click [Show preview] and the new code is executed right away on the preview page.
  • Saving it: If required elements are missing on the preview page (for example, your script does something on history pages), you will have to save the script in order to test it. However, it's not convenient and creates unnecessary entries in the page history.
  • Execute it in your browser's JavaScript console: All modern browsers come with a JavaScript console and other development tools. You can type or paste and execute your code there; script errors and warnings will also be shown there. How to open the console depends on your browser:
You may need to click the Console tab if a different pane is currently open.

Loading it from a localhost web server[සංස්කරණය]

The best and most recommended way to load a JavaScript file during development is from your local web server (see below for an easy way to install a web server). Put this string in your /common.js:

mw.loader.load( 'https://localhost/wikipediatest.js' );

In some environment, you need write this like[2]:

mw.loader.load( '' );

Then run any web server on your computer and create the wikipediatest.js file in the appropriate folder. The code inside this file will be executed as if it was inside your personal script.

You can edit your wikipediatest.js file with any text editor, perhaps with syntax highlighting and other convenient features, save the file and simply reload any Wikipedia page to see the results. (You don't need to wait, and if your web server is nice or you set it right, you don't even need to bypass your browser cache.)

Most modern code editors and IDEs allow you to set up a localhost server – eg. use atom-live-server in Atom, and Live Server in VS Code. WebStorm and PhpStorm have the feature built in, without requiring an extension. You can also use a third party program such as Node.js's npx http-server command, or XAMPP. Here is a video tutorial of the Node.js method.

On Windows, you could also use for example TinyWeb which is less than 100 kbyte on disk and doesn't require installation. Save and unzip tinyweb.zip for example into c:\Program Files\Tinyweb, create a shortcut to tiny.exe, and add an argument in shortcut properties — path to your folder with wikipediatest.js and any file index.html (required). Start TinyWeb with this shortcut; unload it with Task Manager.

Note that this method doesn't work in Opera 9.50 (and later) due to added security restrictions, see Opera 9.50 for Windows changelog: "Local servers can use remote resources, but not vice versa". In Chrome, it may be necessary to enable SSL, otherwise the script will refuse to load.


Some browsers allow you to automatically execute your JavaScript code on specific web pages. This way you don't have to be logged in to Wikipedia. One example is Tampermonkey. However, making user scripts work with one of these extensions might require some modifications to the script code.

Running pieces of code[සංස්කරණය]

You can run pieces of code on already loaded pages via the JavaScript console. See the guide for doing this in Chrome. It works similarly in most other browsers.

Once you have finished the user script code, you can save it as a page so that others can import it. By convention, scripts are in your userspace and have titles ending in ".js",[n. 1] for example "User:YourUsernameHere/MyCoolScript.js". Others can then install the new script.

Text editors and debugging[සංස්කරණය]

Text editors[සංස්කරණය]

You can use anything from a simple text editor, to a more feature-packed code editor or IDE. Here are some features we recommend:

  • Color code JavaScript code
  • Quickly insert standard JavaScript keywords and methods with Ctrl+↵ Enter
  • Show the list of all functions and quickly jump to any function
  • Code folding
  • If you plan to use non-ASCII characters in string, your text editor should support UTF-8.

Here are some recommended editors, by operating system.

JavaScript Debuggers[සංස්කරණය]

These are typically built into browsers, in their DevTools window. Debuggers allow you to step debug (go through your JavaScript code line-by-line, hover over variables to see their values, etc.)

  • Firefox - use Tools → JavaScript Console which shows all JavaScript and CSS errors.
  • Chrome and Chromium - use Tools → Developer Tools.
  • Safari - Safari → Preferences → Advanced and enable the "Show Develop menu in menu bar" option. Then use Develop → Show Web Inspector to open up the development tools.
  • Opera - use Tools → Advanced → Error Console which shows all JavaScript and CSS errors.

Basic techniques[සංස්කරණය]

Finding elements[සංස්කරණය]

Every HTML element is a node in a DOM model which allows scripts to access the element, for example, on the following HTML page.

<form name="frmname" id="frmid">
	<textarea name="txtname" id="txtid"></textarea>
	<input id="neighbor" />

We can find element textarea:

  • Using its id: $( '#txtid' )
  • In the array of all elements with the same tag: $( 'textarea' )
  • Using an element next to it: $( '#neighbor' ).prev()
  • As a child of its parent: $( '#frmid' ).children( 'form' )
  • As a form element, using name: $( '#frmid [name="txtname"]' )

This example on jsFiddle

The jQuery API reference is an excellent source for documentation.

Checking the current page[සංස්කරණය]

Many scripts are supposed to work only on some pages. You can check:

  • The page type
if ( mw.config.get( 'wgAction' ) === 'history' ) {  // Continue only on history pages.
if ( mw.config.get( 'wgCanonicalNamespace' ) === 'User_talk') {  // Continue only on User_talk pages.
if ( mw.config.get( 'wgPageName' ) === 'Article_name' ) {  // Continue only for the article "Article name".
  • Presence of elements (only in second and third parts of the script)
function func_start() {
   if ( $( '#editForm' ).length == 0  ) return; //No edit form  ? exit
   // …

Portlets (menus and tabs)[සංස්කරණය]

Portlets are MediaWiki's name for groups of links located in the topbar and sidebar. Here is a diagram of portlet ID's.

MediaWiki portlets as seen in Vector legacy skin.

List of portlets[සංස්කරණය]

  • Top
    • p-personal - The links at the very top right of the page. "personal" stands for "personal tools".
    • p-namespaces - The tabs on the left that never collapse. Not recommended, not much space. The article and talk tabs are located here.
    • p-views - The tabs in the middle that never collapse. Not recommended, not much space. The favorite page star tab is located here.
    • p-cactions - The items in the "More" tab's dropdown menu. "cactions" stands for "content actions".
    • p-search - Adding things here will mess up the appearance of the search box. Not recommended.
  • Left
    • p-logo - Adding things here will mess up the appearance of the logo. Not recommended.
    • p-navigation
    • p-interaction - Has the title "Contribute".
    • p-tb - Has the title "Tools". TB stands for toolbox.
    • p-coll-print_export - Has the title "Print/export". Not a good place to add things, since this should just be for printing and exporting.
    • p-wikibase-otherprojects - Has the title "In other projects". Not a good place to add things, since this should just be for links to other projects such as Wikisource, Wikibooks, etc.
    • p-lang - Has the title "Languages". Not a good place to add things, since this should just be for languages.

Portlet structure[සංස්කරණය]

<div id="p-myname" class="portlet">
 <div class="body">
  <li id="…"> <a >  //Links
  <li id="…"> <a >
  … …

Adding elements[සංස්කරණය]

There is a special function in mediawiki.util.js that simplifies the process of adding your own links to portlets. The advantage of using this function is that your code should work across all skins.


  • portletType,
  • linkURL, - set to # if you don't need to open a page, and want to use a JavaScript listener instead
  • linkText,
  • elementID, (optional) - suggest using a prefix such as ca-, pt-, n-, or t-
  • tooltip, (optional)
  • keyboardShortcutKey, (optional) - set to null if you don't need it [1]
  • nextNode, (optional) - element that this will be added in front of


// Several examples of portlet links

// Adds a link to your js file to the toolbox. tb = toolbox
mw.util.addPortletLink ( 'p-tb', mw.util.getUrl( 'Special:MyPage/common.js' ), 'My JS', 'pt-myvector', 'Visit your js file');

// Add a link to the edit page for your Notes in your personal links
// Note: We assume that short/pretty URLs are in use with ?action, ideally you would check for that.
mw.util.addPortletLink ( 'p-personal', mw.util.getUrl( 'Special:MyPage/Notes' ) + '?action=edit', 'My notes', 'pt-mynotes', 'Edit your personal notes' );

// Adds a link to prefix index for the current page to the toolbox
mw.util.addPortletLink ( 'p-tb', mw.util.getUrl( 'Special:Prefixindex/' + mw.config.get( 'wgPageName' ) ), 'Prefixindex', 'tb-prefixindex');

// Adds a link to logs for your account
mw.util.addPortletLink ( 'p-personal', mw.util.getUrl( 'Special:Log/' + mw.config.get( 'wgUserName' ) ), 'My logs', 'pt-mylogs');

Or you can use JQuery. Simply attach it in another place with .append(), .prepend(), .before(), or .after(). [2][3]. Warning: This is very fragile. You may get it working on a couple skins, but a couple other skins may look broken.

// Add a clickable button on the edit article page, above the edit summary.
$('.editOptions').prepend('<button type="button" id="my-custom-button">Do Things</button>');

// Add a listener to your button, that does something when it is clicked.
$('#my-custom-button').click(function(e) {
	// do things

Removing elements[සංස්කරණය]

To hide an element, you can use JQuery's .hide() function.

// Example: remove special characters toolbar from edit page
$( '#editpage-specialchars' ).hide();

// Or modify the CSS directly
$( '#editpage-specialchars' ).css( 'display', 'none' );

Or you can do it by placing code in common.css:

#editpage-specialchars {


Textarea with article wikicode[සංස්කරණය]

The most important element on the edit page is a <textarea> with the article text inside. You can reference it with

var $textbox = $( '#wpTextbox1' );

You can manipulate it using the jquery.textSelection ResourceLoader module.

var $textbox = $( '#wpTextbox1' );
$textbox.textSelection( 'setContents', 'This is bold!' );
$textbox.textSelection( 'setSelection', { start: 8, end: 12 } );
$textbox.textSelection( 'encapsulateSelection', { pre: '<b>', post: '</b>' } );
// Result: Textbox contains 'This is <b>bold</b>!', with cursor before the '!'

Or you can grab <textbox>'s text, create a string, modify it, then write it back. Note; other editing tools might not recognise your changes or cause conflicts if you use this methodology instead of the textSelection api.

// Get value.
let value = $('#wpTextbox1').val();

// Your code goes here. Do things to value. RegEx, .replace(), concatenate, etc.

// Then write it back.

Editing toolbar[සංස්කරණය]

WikiEditor is now the default toolbar when editing the source code of articles, but some users are still using the original toolbar. You can turn on and off WikiEditor by checking and unchecking the "Enable the editing toolbar" check box in your preferences.[n. 2][n. 3]


There is another edit panel under textarea. Usually it's generated from MediaWiki:Edittools by Extension:CharInsert and consists of a lot of JavaScript links. In the English Wikipedia, this approach was replaced by MediaWiki:Gadget-charinsert.js and MediaWiki:Gadget-charinsert-core.js.

Doing something after another user script[සංස්කරණය]

Sometimes you may want to add or remove something from the DOM, but another user script edits the same area of the DOM. It can be random which user script finishes first, creating a race condition.

One way to coordinate this is use the mw.hook interface. Perhaps the other script sends a wikipage_content event when it's done, or can be modified to do so (or you can ask the maintainer).

Another way to avoid this is to use the DOMNodeInserted or DOMNodeRemoved events to listen for when the other user script is finished, ensuring that your user script executes last.

$('body').on('DOMNodeInserted', '.preferences-link.link', function() {
    // do things

User settings[සංස්කරණය]

If you want your users to be able to manually set configuration variables, one way to do this is to have them place window.scriptNameSettingName = 'value here'; in their common.js file. Then within your user script, you can read this value with if ( window.scriptNameSettingName == 'value here' ).

Notice that "scriptName" is one of the pieces of the variable name. This is important to help make sure the variable is unique.

Do not use let scriptNameSettingName = 'value here'; in the common.js file. If the user forgets the setting, you may get undeclared variable errors.

If you want your user script to write and save configuration settings while it is running, you may want to have it write to its own .js file in the user's userspace. See twinkleoptions.js or redwarnConfig.js for examples.

Preventing bugs[සංස්කරණය]

<nowiki> tags[සංස්කරණය]

You may want to place the following code at the top and bottom of your user script, in a comment. This will help prevent bugs, such as ~~~~ turning into your signature when you update your code.


Your code here.


Function scope[සංස්කරණය]

Don't declare named functions in the global namespace. For example, this is bad:

function submitEdit() {/* do stuff */}

$(function{/* main code here */});

What if another of your user scripts also declares a submitEdit() function, but you have modified the code? This can lead to race conditions and hard-to-trace bugs. Instead, use classes named after your script, or place all your functions inside of $(function {});. JavaScript allows nested functions.

    function submitEdit() {/* do stuff */}
    /* main code here */

AJAX (asynchronous JavaScript and XML) is a popular name for a web programming technique that queries the server or fetches content without reloading the entire page.

While programming AJAX can be complex, libraries of functions can make it much easier. Since the 1.16 release, MediaWiki comes with the jQuery library, which provides a convenient framework for easily making Ajax requests.

Common problems[සංස්කරණය]

  • AJAX programmers commonly run into problems if they don't account for AJAX's asynchronicity. If you try to pop up a box with another page's content, you will almost certainly pop up a box containing null. This occurs because the script continued even though the query wasn't finished.

    To correct the problem, you need to use callback functions. Place the next portion of code after a query into a function, and call the function when the query completes. jQuery makes this very easy to do.

  • AJAX scripts cannot reach a page on a different server (for example, google.ca or en.wikisource.org from en.wikipedia.org). Trying to do so will cause the script to halt with or without error. This can be circumvented using a proxy on the current server, but none is available for Wikimedia user scripts.

Basic examples[සංස්කරණය]

MediaWiki provides some modules with helper functions which facilitate the use of its API. The main modules available are

If your script makes use any method or code provided by these modules, remember to indicate the dependencies with mw.loader.using or, in case of gadgets, on its definition at MediaWiki:Gadgets-definition.

This API has several advantages especially when dealing with POST requests. It provides automatic token refresh and retry, handles various error situations and does parameter request building for several common use cases like rolling back a revision.

Be sure to follow the user agent policy by setting a user agent header (see code there). See also mw:API:Etiquette.

Fetch page content[සංස්කරණය]

Fetching a page content can be done using GET.

	url: mw.util.getUrl( 'Wikipedia:Sandbox' )
.then(function( data ) {
	alert( 'The remote page contains:\n' + data );
.catch(function() {
	alert( 'The ajax request failed.' );

Get the wikitext of a page[සංස්කරණය]

Using module mediawiki.api[සංස්කරණය]

Note: make sure to add "mediawiki.api" to your dependencies!

function doSomethingWithText( wikitext ) {
	/* .. */
	alert( 'The wikitext of the page is:\n\n' + wikitext );
function doSomethingInCaseOfError () {
	/* .. */
	console.log( 'err' );
(new mw.Api()).get( {
	prop: 'revisions',
	rvprop: 'content',
	rvlimit: 1,
	indexpageids: true,
	titles: 'Wikipedia:Sandbox'
} )
.then( function ( data ) {
	var q = data.query,
		id = q && q.pageids && q.pageids[0],
		pg = id && q.pages && q.pages[ id ],
		rv = pg && pg.revisions;
	if ( rv && rv[0] && rv[0]['*'] ) {
		doSomethingWithText( rv[0]['*'] );
} )
.catch( doSomethingInCaseOfError );
Using plain jQuery[සංස්කරණය]
		format: 'json',
		action: 'query',
		prop: 'revisions',
		rvprop: 'content',
		rvlimit: 1,
		titles: 'Wikipedia:Sandbox'
	.then(function ( data ) {
		var page, wikitext;
		try {
			for ( page in data.query.pages ) {
				wikitext = data.query.pages[page].revisions[0]['*'];
				doSomethingWithText( wikitext );
		} catch ( e ) {
	.catch( doSomethingInCaseOfError );

Edit a page and other common actions[සංස්කරණය]

Scripts can perform common actions (like editing, protection, blocking, deletion, etc.) through the API. These actions require an edit token, which is valid for any action during the same session. (However, you should get a new token for different tasks in case this changes in the future.)

The code below shows how to edit a page, but it can easily be adapted to other actions by reading the API documentation.

Using module mediawiki.api[සංස්කරණය]

Note: make sure to add "mediawiki.api" to your dependencies!

// Edit page via the mw.Api module.
// postWithEditToken( {} ) may be used instead of postWithToken("csrf", {} )
// for actions such as editing that require a CSRF token.
// The line "text: info.text," will cause the call 
// to replace entire page content with supplied data.
// alternatively, one can append or prepend the data to the page, by using
// "appendtext: info.text," or "prependtext: info.text," instead.
// when using "appendtext", it is possible to append the text to a specific section,
// by setting the optional field "section".
function editPage( info ) {
	var api = new mw.Api();
	api.postWithToken("csrf", {
		action: 'edit',
		title: info.title,
		text: info.text, // will replace entire page content
		summary: info.summary
	} ).done(function( data ) {
		alert( 'Page edited!' );
	} ).fail( function(code, data) {
		console.log( api.getErrorMessage( data ).text());
	} );
	title: 'User:' + mw.config.get( 'wgUserName' ) + '/Sandbox',
	text: 'Cool! It works! :-) ~~' + '~~',
	summary: 'Trying to edit my sandbox [[Project:User scripts/Guide|using API]]...'
Using plain jQuery[සංස්කරණය]
// Edit page (must be done through POST)
// the line "text: info.text," will cause the call 
// to replace entire page content with supplied data.
// alternatively, one can append or prepend the data to the page, by using
// "appendtext: info.text," or "prependtext: info.text," instead.
// when using "appendtext", it is possible to append the text to a specific section,
// by setting the optional field "section".
function editPage( info ) {
		url: mw.util.wikiScript( 'api' ),
		type: 'POST',
		dataType: 'json',
		data: {
			format: 'json',
			action: 'edit',
			title: info.title,
			text: info.text, // will replace entire page content
			summary: info.summary,
			token: mw.user.tokens.get( 'csrfToken' )
	.then (function( data ) {
		if ( data && data.edit && data.edit.result && data.edit.result == 'Success' ) {
			alert( 'Page edited!' );
		} else {
			alert( 'The edit query returned an error. =(' );
	.catch ( function() {
		alert( 'The ajax request failed.' );
	title: 'User:' + mw.config.get( 'wgUserName' ) + '/Sandbox',
	text: 'Cool! It works! :-) ~~' + '~~',
	summary: 'Trying to edit my sandbox [[Project:User scripts/Guide/Ajax|using AJAX]]...'

Load JavaScript from Wiki page[සංස්කරණය]

Security warning: Do not load Wikipedia pages that do not end in .js into your script using this method, because anybody can edit those pages.

let title = "User:YourName/YourScript.js";
mw.loader.load( "https://en.wikipedia.org/w/index.php?title="+title+"&action=raw&ctype=text/javascript" );

Load JSON from Wiki page[සංස්කරණය]

JSON is useful when you want to import complex data into your script. For example, maybe you have a bot that publishes certain data to a Wiki page regularly, and you want your script to read that data.

Careful with ctype. Set it to raw for normal Wiki pages, and application/json for pages where a template editor or admin has set the Content Model to JSON.

let jsonData;
let title = "User:YourName/YourData.json";
$.getJSON(mw.config.get('wgScriptPath')+'/index.php?action=raw&ctype=application/json&title='+title, function(data){
	jsonData = data;

Working with CSS[සංස්කරණය]

Some user scripts also use some CSS code, or even are built with CSS only. Then you need to code and test CSS code. That can be done in your /common.css, but it is slow and messy.

Instead, you can load a CSS file from your local web server (see the previous section for an easy-to-install web server). Put this line at the very top of your /common.css:

@import "http://localhost/wikipediatest.css";

Note! Such @import statements must come before any other declarations in your CSS. But there can be /* comments */ above them.

An alternative way is to put this line in your Javascript file instead:

mw.loader.load( 'http://localhost/wikipediatest.css', 'text/css' );

Publishing a CSS file[සංස්කරණය]

Once you have finished the CSS code, you either need to paste it into your /vector.css if it is only for personal use. Or if it is for use by others then you should upload it to for instance User:Yourname/yourscript.css. Then other users can import it by putting the following line in their /common.js file. Note, that is in their ".js", not their ".css".

importStylesheet( 'User:Yourname/yourscript.css' );

If the CSS should be used together with a user script written in JavaScript then you can make it easy for the users. Simply put the line above in the JavaScript code for your user script, then the users only need to "install" your JavaScript.

For completeness, in case someone wonders, users can import your User:Yourname/yourscript.css from their /common.css too. This of course has the advantage that it works even if the user has JavaScript disabled. Although it takes this slightly complex line of code:

@import "/w/index.php?title=User:Yourname/yourscript.css&action=raw&ctype=text/css";
  1. 1.0 1.1 The actual requirement is that the page have contentmodel "javascript". Making a page whose title ends in ".js" will automatically give it that content model and indicates to readers that the page contains JavaScript.
  2. See mw:Extension:WikiEditor/Toolbar customization for information on how to customize WikiEditor.
  3. See User:V111P/js/addToolbarButtons for a script which allows you to easily add buttons to whichever of the two toolbars the user is using.
