Meta:Internationalization guidelines

Meta-Wiki aims to be a multi-language wiki, so most pages are expected to be translatable and translated. To be translatable through Translate extension, a page should be tagged with <translate>...</translate> (i.e. internationalized) then marked for translation by a translation admin. This page aims to present guidelines for page internationalization on Meta-Wiki.

General guidelines

Generally, you should follow Translate extension’s guidelines about marking a page for translation: when possible, please avoid to manually split translation units closing the translate tag, you should let empty lines do the job instead.

Main new 2020 syntax requirements

• If you want to split a list into several units, do not put linebreaks inside of texts which should become one unit. You should also exclude bullet points/numbering hashtags from the translate tag.
• If you insert a translate tag inside a parameter value of a template call, ensure the parameter is named (else add a numeric name, like 1=).

Segmentation examples

Bad syntax	Good syntax
== <translate>Section heading</translate> == <translate>This is a paragraph.</translate> <translate>This is another paragraph.</translate> {{Template}} == <translate>Another heading<translate> ==	<translate> == Section heading == This is a paragraph. This is another paragraph. </translate> {{Template}} <translate> == Another heading == </translate>
<translate> * This is a long list: ** There are more than 160 words in this list, ** or there are more than 8 items. </translate> <translate> * So it is better to split it in several smaller units. * But we must exclude bullet points from translate tags to keep the list accessible. </translate>	* <translate>This is a long list:</translate> ** <translate>There are more than 160 words in this list,</translate> ** <translate>or there are more than 8 items.</translate> * <translate>So it is better to split it in several smaller units.</translate> * <translate>But we must exclude bullet points from translate tags to keep the list accessible.</translate>

Specific elements

Links

Any page which could be translated should be linked with Special:MyLanguage/ prefix, even if it not actually internationalized. The main pages which do not need this prefix are talk pages and templates without textual content. To make translation easier, please wrap target of internal links inside <tvar name=1> … </tvar> (tvar name can be a number only, this is sufficient).

For links to Wikipedia article, you should use {{lwp}} template for the target and wrap it inside a tvar. E.g. [[<tvar name=1>{{lwp|Rosa Parks}}</tvar>]] produces en:Rosa Parks in English pages and fr:Rosa Parks in French pages.

For other cross-wiki and external links, if a translation exists, you should not put the link target inside tvar. Of course, if the target website has a language detection system (like MediaWiki's Special:MyLanguage/), you may use this system and put the full link inside tvar.

Bad syntax	Good syntax
<translate> This is a text with an [[internal link]] and an [https://openstreetmap.org external link]. </translate>	<translate> This is a text with an [[<tvar name=1>Special:MyLanguage/internal link</tvar>|internal link]] and an [<tvar name=url>https://openstreetmap.org</tvar> external link]. </translate>

Categorization

You should exclude category declarations from translate tags. Instead, add {{#translation:}} after the category name: [[Category:Target category{{#translation:}}]]. This way, only the main English page is categorized into the target categories, translation pages are categorized in per-language categories.

Bad syntax	Good syntax
<translate>[[Category:Wikipedia]]</translate>	[[Category:Wikipedia{{#translation:}}]]

Images

Thumbs and large images

If the image can be localized (e.g. it contains some text and a translated version exists), it should be fully included in translate tags.

Else, you should only wrap alt= value in <translate nowrap> tags and caption in <translate> tags.

If left or right is used as image parameter: remove it if it is useless (thumbnails default to right in English), or replace it with {{dirleft}} or {{dirright}}.

Bad syntax	Good syntax
<translate> [[File:landscape.jpg |thumb |left |alt=sunset |Photo of a beautiful landscape]] </translate>	[[File:landscape.jpg |thumb |{{dirleft}} |alt=<translate nowrap>sunset</translate> |<translate>Photo of a beautiful landscape</translate>]]
[[File:English Wikipedia screenshot.png|thumb|right|<translate>Wikipedia homepage</translate>]]	<translate> [[File:English Wikipedia screenshot.png|thumb|Wikipedia homepage]] </translate>

Icons

Inline icons may be simply wrapped in a <tvar name=img>.

Bad syntax	Good syntax
<translate> [[File:pretty hello word.png|alt=Hello]] everybody! [[File:smiley.png|alt=🙂]] How are you? </translate>	<translate> [[File:pretty hello word.png|alt=Hello]] everybody! <tvar name=icon>[[File:smiley.png|alt=🙂]]</tvar> How are you? </translate>

Translation variables

Translation variables (<tvar name=name></tvar> syntax) should be used to hide text from translators in order to prevent them from translating it.

The following examples should be wrapped inside tvar:

• automatically-localized or non-localizable link targets,
• usernames,
• numbers likely to change (they should be wrapped inside {{formatnum:}} then inside tvar),
• tag attributes (e.g. <span <tvar name=attr>class="css_class" style="background-color:blue"</tvar>>hello</span>),
• template name and parameters (e.g. {{<tvar name=1>center|5px</tvar>|hello}}).

The following examples should not be wrapped inside tvar:

• people and place names (even if they are rarely translated, they may be transliterated),
• XML tags without attributes, like <code> (the translation interface handles them),
• localizable link targets (i.e. links to multilingual website).

Translation variable names

To help translators, please keep tvar names as short and readable as possible. If translators don’t need to know their content, using numbered names is a good idea because digits are quick to type for most translators and are common in many languages (so that most beginners do not accidentally translate them).

However if tvar is inside a sentence, it should have an explicit name to allow translators to understand what it contains and so write it easily in the right place in their translation (it is pretty common for an email address, URL, wikitext tag name…).

Avoid putting proper names (people, places…) inside tvar: even if they are rarely translated, as they may be transliterated in several languages.

You may put parts of complex wikitext or HTML inside tvar, but please ensure the resulting wikitext for translators is balanced.

Templates

You may prepare a template for translation like any page, but you should ensure the “Enable translation aware transclusion for this page” checkbox is checked when you mark the page for translation.

If your template is expected to be included in non-translatable pages (e.g. user pages) and should be even translated in these pages, you can use the pre-2021 hack with switch, replacing uselang={{PAGELANGUAGE}} with uselang={{int:lang}} in the code shown below.

Pre-2021 hacks

Before MediaWiki 1.36.0-wmf.32 (2021-02-23), you should ensure English pages include the /en subpage of a template instead of a template directly.

One way was to replace each occurrence of {{my translated template|param}} with {{TNT|my translated template|param}}, except in templates or transcluded pages which should contain {{ {{TNTN|my translated template}} |param}} instead.

Another way was to edit the template to make it call itself {{TNT}}. To this end, you should put the full template code inside a switch which evaluated an empty translate tag, with a default case which called {{TNT}}.

{{#switch:<translate></translate>
|=<full template code>
|#default={{#invoke:Template translation|renderTranslatedTemplate|template={{subst:FULLPAGENAME}}|uselang={{PAGELANGUAGE}}|noshift=1}}
}}
