Templates download/Language switcher

Starting with BlueSpice 4.3, a language switcher is automatically created for subpages or interlanguage links and this template is no longer needed.

Download

This download file includes two versions of a language switcher. Supported languages can be defined in the templates.

Importing the template

The import file is included in the archive file HW-LanguageSwitcher.zip. Unpack the zip file first.

On the page Special:Import follow these steps:

1. Select file and choose HW-LanguageSwitcher.xml.
2. Enter an Interwiki prefix. Since this field is required, simply add hw (for hallowelt).
3. Keep the selection Import to default locations.
4. Click Upload file... .

The templates are now available in your wiki.

Pages included in the import

The xml import creates the following files in your wiki:

• Template:Languages
• Template:Languages/styles.css
• Template:InterLanguages
• Property:Languages/tracklang
• MediaWiki:Lang
• MediaWiki:Lang/de
• MediaWiki:Lang/en
• MediaWiki:Lang/fr
• MediaWiki:Lang/nl

How it works

Template:Languages

This template is used to switch between a page and its translated versions when the translations are maintained as subpages.

The template defines some variables to determine which languages you want to support. It automatically determines the content language of your wiki installation. This variable "cl" is required and must not be deleted.

• You need to define at least one language for the switcher to make sense. Each language variable is named as lowercase l (for language) "l1", "l2",.... The value needs to be provided as the ISO 639-1 language code for the language. For Spanish, you would define:

  {{#vardefine:l4|es}}
  

• After defining the variables, you need to add them to the actual switcher:

  {{#switch: {{SUBPAGENAME}}
  |{{#var:l1}}={{#var:switcher}}
  |{{#var:l2}}={{#var:switcher}}
  |{{#var:l3}}={{#var:switcher}}
  |{{#var:l4}}={{#var:switcher}}
  |{{#var:clswitcher}}}}
  

• A tracking property enssures that the different languages are available for further processing through Semantic MediaWiki. This allows to create page lists of the different languages.:

  <!-- set tracking property //-->
  [[Languages/tracklang::{{#switch: {{SUBPAGENAME}}|{{#var:l1}}={{#var:l1}}|{{#var:l2}}={{#var:l2}}|{{#var:l3}}={{#var:l3}}|{{#var:l4}}={{#var:l4}}|{{#var:cl}}}}]]
  

• Alternatively, especially in BluesSpice free (where no SMW functions and therefore no attributes are available by default), tracking categories can be used. These are commented out in the template by default. The comment must therefore be removed and all languages tracked as a category:

  {{#switch: {{SUBPAGENAME}}|{{#var:l1}}=[[Category:{{#var:l1}}]]|{{#var:l2}}=[[Category:{{#var:l2}}]]|{{#var:l3}}=[[Category:{{#var:l3}}]]|{{#var:l4}}=[[Category:{{#var:l4}}]]|[[Category:{{#var:cl}}]]}}
  

• In addition, you should add the language to the template description for the extension TemplateData:

  "description": {
          "en": "Language switcher",
  		"de": "Sprachwechsler",		
  		"fr": "Sélecteur de langue",
  		"nl": "Taal verandering",
  		"es": "Cambiador de idioma"
  	}
  

Template:InterLanguages

This template is used to switch between a page and its translated versions when the translations are not maintained as subpages, but are technically not associated at all.

The template defines some variables to determine which languages you want to support. The variable "self" defines the current page. It is required and must not be deleted.

The language variables are defined just like in the template Languages. If you define additional language variables, the newly defined languages has to be added to the language menu. The links are created in the following container:

<div id="langbar-hz">
...
</div>

Simply add each language with the l-number matching your language variable by copying this line and replacing the number:

{{#if: {{{pgnamel4|}}}|{{#switch:{{{pgnamel4|}}}|{{#var:self}}=[[{{FULLPAGENAME}}{{!}}{{#var:l4}}]]|[[{{{pgnamel4}}}{{!}}{{#var:l4}}]]}}|}}

In addition, you need to add the language to the template description and the available fields in the TemplateData editor.

In source editing mode:

1. Click Manage TemplateData
   

   Manage TemplateData
   
   
2. Click Add parameter
   

   Add new languages (as parameters)
3. Select any new language you have added and click Apply.
   

   Selecting a newly added paramter
4. Add the language abbreviation for the new language as a label and activate the Suggested checkbox and click Done.
   

   Parameter settings
5. Click Add language to add a new template description for this language.

6. Select the user language that corresponds to the current language parameter.
   

   select user language
   
   
7. Enter a template description and click Apply. This description is shown when the user selects a template in the visual editor.

Important!If you have changed the original default values for the language variables, make sure to change the language labels here accordingly. The labels for the l1, l2, l3,... languages need to match.

check correct language associations

Alignment of the language switcher

By default, the language switcher appears on the right side of the page. To display it on the left side, change the following line in the page Template:Languages/styles.css:

#langbar-hz {text-align: left;}

Adding the language switcher to a page

It is possible to use both language switchers in the same wiki. They connect language versions in different scenarios:

• Using the language switcher template Languages (for language versions that are maintained as subpages)
• Using the language switcher template InterLanguages (for language versions that are maintained as independent pages)
