The Babel extension adds a parser function to replace the old Babel system that completely relied on templates. If an unrecognized language parameter is specified, it will see if there is an existing template with the name and include that.

On Wikimedia projects, the noun Babel (in reference to the Tower of Babel) refers to the texts on user pages aiding multilingual communication by making it easier to contact someone who speaks a certain language. The idea originated on the Wikimedia Commons and has also been implemented on many other wikis.

Installation

Download and move the extracted Babel folder to your extensions/ directory.
Developers and code contributors should install the extension from Git instead, using:cd extensions/ git clone https://gerrit.wikimedia.org/r/mediawiki/extensions/Babel
Add the following code at the bottom of your LocalSettings.php file:
```
wfLoadExtension( 'Babel' );
```
Run the update script which will automatically create the necessary database tables that this extension needs.
Configure as required.
Done – Navigate to Special:Version on your wiki to verify that the extension is successfully installed.

The CSS is located in the file resources/ext.babel.css. You can change the style as desired by overriding them in the page MediaWiki:Common.css.
If the CLDR extension is found language names are taken from that (where translations are unavailable), otherwise built in MediaWiki language names and English defaults are used.

Usage

Syntax for the #babel parser function is as follows:

{{#babel: babelcode1 | babelcode2 | ... }}

Add one of the following codes for each language you speak or understand, separated by |, where xx is the MediaWiki language code, ISO 639-1 code, or ISO 639-3 code for the language. The general usage of each code level is as follows:

xx-0: If you don't understand the language at all.
xx-1: Basic ability—enough to understand written material or simple questions in this language.
xx-2: Intermediate ability—enough for editing or discussions.
xx-3: Advanced level—though you can write in this language with no problem, some small errors might occur.
xx-4: "Near-native" level—although it's not your first language from birth, your ability is something like that of a native speaker.
xx-5: Professional proficiency.
xx or xx-N: Native speakers who use a language every day and have a thorough grasp of it, including colloquialisms and idioms.

To include any other template, add the name of the template, e.g., add User CSS if you want to include Template:User CSS. A prefix or suffix may be added to template names (e.g., User at the beginning) depending on the local configuration. This can be used to restrict the selection and reduce the length of parameters; for example, CSS could include Template:User CSS if configured in such a way.

Parameters

To remove the header and footer, use plain=1 as the first parameter, e.g., {{#babel: plain=1 | babelcode1 | babelcode2 | ... }}. This makes it easier to use Babel with other userboxes.

To hide categories, use the nocat=1 parameter as the first parameter, e.g., {{#babel: nocat=1 | babelcode1 | babelcode2 | ... }}.

Please note that only one of the parameters above is allowed. At the moment, it is not possible to use both parameters; for example, {{#babel: nocat=1 | plain=1 | babelcode1 | babelcode2 | ... }} will not work.

Categorization

If categorization is enabled, the extension creates categories using the Babel AutoCreate bot with the text specified in MediaWiki:babel-autocreate-text-levels and MediaWiki:babel-autocreate-text-main. With basic settings, the categories that the bot creates are not categorized, and to fix this, it is recommended to do the following:

Create a template {{Babel category }} that will generate categories.
Replacing text on MediaWiki:babel-autocreate-text-levels with
```
{{Babel category|level=$1|language=$2|ISO=$3}}
```
Replacing text on MediaWiki:babel-autocreate-text-main with
```
{{Babel category|language=$1|ISO=$2}}
```

This will allow you to categorize categories automatically, and if something happens, you can simultaneously replace the categorization and text in all categories.

Configuration

Configuration parameters

Babel has several configuration parameters which can be modified in LocalSettings.php .

$wgBabelLanguageCodesCdb: (string) the path of the language code database file, the default should suffice.
$wgBabelLanguageNamesCdb: (string) the path of the language name database file, the default should suffice.
$wgBabelCategoryNames: (array of string or boolean, indexed by the strings "1", "2", … "5", "N") where each entry is the name of a category for the skill level indicated by its index, possible variable elements are: %code% (language code), %wikiname% (the name of the language in the wiki's content language), and %nativename% (the name of the language in its language). To disable adding a category for a particular level, set the corresponding value to false.

For example:

$wgBabelCategoryNames = [
	'0' => 'User %code%-0',
	'1' => 'User %code%-1',
	'2' => 'User %code%-2',
	'3' => 'User %code%-3',
	'4' => 'User %code%-4',
	'5' => 'User %code%-5',
	'N' => 'User %code%-N',
];

will use categories like "Category:User en-0" and "Category:User fr-N". The default is just "Category:Fr-N" and so on.

$wgBabelMainCategory

(string) Name of the main (non-level) category for each language to which all users of that language are added. Set to false to disable; defaults to format "Category:Fr". It accepts the same format as $wgBabelCategoryNames above. Example:

$wgBabelMainCategory = 'User %code%';

$wgBabelDefaultLevel: (string) Default ability level to use when none is specified, should be an index from $wgBabelCategoryNames, that is one of the strings "1", "2", … "5", "N". Default is "N".
$wgBabelUseUserLanguage: (boolean) Whether to use the user interface language for the header and footer message. If false (default), it will be in the page content language. This is because using the user interface language may fragment the parser cache.
$wgBabelCategorizeNamespaces: Array of namespaces to only add automatic categorization to. For example, if $wgBabelCategorizeNamespaces = [ NS_USER ];, then Babel will only add categories to pages in the user namespace. The default is null, which means categorizing all namespaces.
$wgBabelCategoryOverride: Whether to allow Babel categories to be overridden on the wiki using MediaWiki:Babel-category-override
$wgBabelAutoCreate: Whether to auto-create categories.

System messages

Several customizations can also be made using MediaWiki namespace messages.

MediaWiki:babel-template "Template:User $1": The format of template names when one is being included.
MediaWiki:babel-portal "": The format of the link's target from the language code. Set to the empty string to not link the language code.
MediaWiki:Babel-autocreate-user "Babel AutoCreate": Username to be used for auto-creation of Babel related categories
MediaWiki:babel-autocreate-text-levels "Users in this category indicate they have skill level $1 for language $2.": Text to insert into auto-created categories for different language levels. You have to change this if you want them to be auto-categorized in the main category of the respective language ($wgBabelMainCategory).
MediaWiki:babel-autocreate-text-main "Users in this category indicate their knowledge of language $1.": Text to insert into auto-created categories for non-level categories. You have to change this if you want them to be auto-categorized in a parent category for all languages.
MediaWiki:babel "Babel user information": The header of the babel box. Set to - to not display a header.
MediaWiki:babel-url "m:User language": The page name where information on the babel extension can be found. Set to - to display no link in the header.
MediaWiki:Babel-footer "": The footer of the babel box. Set to - to not display a footer.
MediaWiki:babel-footer-url ":Category:Babel - Users by language": The page to link to in the footer of the babel box
MediaWiki:Babel-category-override "$1": Overrides any automatically-generated Babel categories. Parameters:
$1 = the category that would be generated normally.
$2 = the language code
$3 = the babel level.
Any categories overridden using this method will not be auto-created to reduce the risk of vandalism or mistaken edits to that page.
