Template parameters
- TemplateData
TemplateData is a way to store information about template parameters (the description of those and of the whole template) for both humans and machines. It is used by VisualEditor and possibly other tools like Upload Wizard.
Existing template documentation
At Wikimedia Commons, it is recommended to use {{TemplateBox}} with either useTemplateData=1 or useTemplateData=only on the /doc subpage and transcluding it with {{Documentation}} into the template. <nowiki>-tags can be wrapped around the arguments, if required, to avoid templates being expanded.
Newly created template documentation and imports
Another option, especially for imported templates, or for users with JSON experience, is placing raw <templatedata>-tags into the Wikitext of the template, as described in various Wikipediae.

| Parameter | Description | Type | Status | |
|---|---|---|---|---|
| Default Fallback | default |

| English | en | String | required | |
| Language Code | lang | Language code (only needs to be provided if the language displayed is to be fixed and independent of the user’s preferences). {{#if:{{{lang|}}}|{{{lang}}}|{{int:Lang}}}} is not necessary.

| Recommended use at | Categories, galleries | File description pages (deprecated, can be safely replaced by {{Multilingual description}}) | Small templates, whenever the previous options are not suitable (removes the visual indication of the language before each translated text) | Data tables with translated cells or larger templates, when used on pages that do not have language subpages (e.g. not having Main page/en, Main page/de) and where the language displayed will be automatically determined by the language set in user preferences
|
Data tables with translated cells or larger templates, when used on pages that do have language subpages; most of the time these will be pages prepared with the Translate Extension |
| Requires JavaScript enabled for folding | Yes | No | |||
| Folding can be disabled by user | Yes | No | |||
| Folding is done server-side | No | Yes | |||
| Folding when at least n languages are provided | 1 (all translations are shown without folding if the preferred language selected by the user has no matching translation) | 4 | 1 | ||
| Detection of duplicate, incorrect, or unsupported language codes | Yes | No | Yes | Duplicate language codes are impossible by design. Incorrect or unsupported codes are never displayed, but not reported. The Translate extension's interface (if it's used on the translation subpages) doesn't let the user create translations with invalid codes, but other methods (e.g. entering the translation's URL directly) allow it without any warning. | |
| Allows the same translation to be used for several languages | Yes | No | Yes | ||
| Supports language fallbacks | No | Yes | No | ||
| Collation order of languages (when not folded) | Consistent order by native language name, languages grouped by script:
|
As provided by the user in the wikitext (any inconsistent order may be difficult to lookup visually) | N/A | ||
| Search indexing issues | No (all translations are included on the same page, however search results may be less relevant with many languages mixed) | Yes (may not index all languages depending on search engines, unless there's a list of links for visiting other languages) | Partially (where used; language subpages of templates are indexed) | No (translated pages should include a <languages/> navigation bar for visiting other languages)
| |
| Page size issues | Yes (may exhaust size or time limits in the wiki parser if many languages are included; larger pages to download for all visitors; slower navigation for visitors with slow Internet access; may be costly for visitors with limited data plans) | No (only the content for the selected language or a suitable fallback language is present in the generated page) | |||
| Contains expensive parser functions | No | Yes, checks for several translations along the fallback chain until finds a suitable | Yes, 2–4 checks per call | ||
Examples
Without a default option
Here are a few examples showing template behavior for three languages: English, Italian and Corsu, which defaults to Italian if Corsu text is not available:
| Test | Code | lang=en | lang=it | lang=co |
|---|---|---|---|---|
| No en; default | {{LangSwitch|it=Italian|default=default}}
|
default | Italian | Italian |
| No en; no default | {{LangSwitch|it=Italian|co=Corsu}}
|
LangSwitch Error: no default[1] | LangSwitch Error: no default[1] | LangSwitch Error: no default[1] |
| en; default | {{LangSwitch|en=English|co=Corsu|default=default}}
|
English | default | Corsu |
| en; no default | {{LangSwitch|en=English|co=Corsu}}
|
English | English | Corsu |
| en; skip default | {{LangSwitch|en=English|co=Corsu|default=~}}
|
English | Corsu | |
| en; empty default | {{LangSwitch|en=English|co=Corsu|default=}}
|
English | English | Corsu |
| Skip en; default | {{LangSwitch|en=~|it=Italian|default=default}}
|
Italian | Italian | |
| Skip en; no default | {{LangSwitch|en=~|it=Italian}}
|
Italian | Italian | |
| Empty en; no default | {{LangSwitch|en=|it=Italian}}
|
LangSwitch Error: no default | Italian | LangSwitch Error: no default |
| en; default; skip it | {{LangSwitch|en=English|it=~|co=Corsu|default=default}}
|
English | Corsu | |
| en; default; empty it | {{LangSwitch|en=English|it=|co=Corsu|default=default}}
|
English | default | Corsu |
| en; no default; skip it | {{LangSwitch|en=English|it=~|co=Corsu}}
|
English | Corsu | |
| Forced "lang=co" | {{LangSwitch|en=English|co=Corsu|default=default|lang=co}}
|
Corsu | Corsu | Corsu |
Example for more
<kbd>LangSwitch|de=Grün|es/it/pt=Verde|fr=Vert|default=Green |lang={{{lang|{{int:lang}}}}}}}</kbd> will give Green for language ⧼lang⧽
| red (Q3142) |
bleu (Q1088) |
|---|
This example will translate
red when not English, and bleu when not French
Default option
The default option is intended for providing more language independent option. For example:
{{LangSwitch
|de={{Wd|Warschau}}
|en={{W|Warsaw}}
|fr={{Wf|Varsovie}}
|ja={{W日|ワルシャワ}}
|pl={{WP|Warszawa}}
|ru={{Wr|Варшава}}
|default=[[d:Q270]]
}}
will provide link to Wikipedia articles in case one of the languages provided matches user's language but will link to Commons gallery page (Warsaw) if any other language is used.
The expression {{W|Q270||d}} is equivalent to the shorter [[d:Q270]] (it just does not show the "d:").
Warning
This template SHOULD NOT be used out of software interface purpose. For example it SHOULD NOT be used to manage multilingual description of the subject of a media or a category or whatsoever.
