LangUtils

LangUtils is an extension for MediaWiki, an open-source wiki software package, written by seb26. To wikis that support multiple languages on the same site, LangUtils provides extra tools and functionality for navigation and displaying language-specific content.

Functionality

LangSwitch – 1.16.5+ – enables {{#langswitch:}} and other function hooks to display the correct translation depending on the page. The below function hooks are available: * {{#langswitch:}} – a #switch replacement. Define language strings as separate arguments (e.g. | ru = Russian) and the correct string will display depending on the page language. If string not available, display in English. * {{#ifpagelang:}} – test for a particular page language. Example: {{#ifpagelang:fr|French|Not French}} would provide different outputs. Any instances of '$1' in the text will also be replaced with the code for that page. Example: {{#ifpagelang:de|German|Not German, $1}} would result in "Not German, en" if used on an English page. * {{PAGELANG}} – outputs the page language code. Additionally, another title can be specified: {{PAGELANG:Page/ru}} would output "ru". * {{PAGELANGSUFFIX}} – if the page is non-English, this will output "/xx"; if the page is English, however, no text will be returned. Convenient for creating links to pages depending on the language. Additionally, another title can be specified: {{PAGELANGSUFFIX:Page/ru}} would output "/ru".
SidebarList – 1.14.0+ – adds a list of all existing translations to the navigation links (replaces manual solutions like {{languages}})
- SidebarList also provides links for file pages (for File:Test.png, it will link to File:Test fr.png, File:Test de.png, etc).
PageClass – 1.17.0+ – adds pagelang-xx class to the <body> tag to allow language-specific CSS
ChangeAnonLang – 1.18.0+ – if there is no user logged in (anonymous), change the language of the site interface to match the page language. For example, on Page/de, anonymous users will see the site interface in German as well as the page content. Users who are logged are unaffected, and continue to see the appropriate language specified in Preferences.

Installation

The following code should be added to LocalSettings.php:

wfLoadExtension('LangUtils');

Development

Testing

Developed for, and tested on MediaWiki stable branch (currently 1.39.3).
Untested on 1.18.0 or lower.

TODO

Test on older versions.
WindPower suggestions:
- Logo link modification
  - Solved by changing "MediaWiki:Mainpage/fr" to "Main Page/fr". Investigate into whether overwriting MW interface strings worth it.
- Customize link format (e.g. default "Title/lang", allow for "lang:Title" or other formats)
- Modify link to Special:RandomPage so as to allow proper 'random' pages in languages
- (done) Change site interface language depending on the page language for anonymous users
