メタ:国際化ガイドライン

メタウィキの趣旨とは多言語版ウィキである点で、ほとんどのページは翻訳対象とみなされ実際に訳されています。翻訳拡張機能を介して翻訳対象に指定するには、対象のページを<translate>...</translate> でタグ付けして（つまり国際化する ため）翻訳管理者の手で翻訳のマークアップ を受けます。このページではメタウィキにおけるページの国際化に関するガイドラインを提供します。

一般的なガイドライン

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=).

リンク

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. [[{{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.

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.

<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}}.

[[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">.

Translation variables

Translation variables (</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}}),
• parts of complex wikitext or HTML (but please ensure the resulting wikitext for translators is balanced).

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 using spaces, underscores or letters with diatrics in tvar names as well.

Templates

You may prepare a template for translation like any page, but you should ensure the “このページの翻訳を意識した参照読み込みを有効にする” 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>
|=<span lang="en" dir="ltr" class="mw-content-ltr"><full template code></span>
|#default={{#invoke:Template translation|renderTranslatedTemplate|template={{subst:FULLPAGENAME}}|uselang={{PAGELANGUAGE}}|noshift=1}}
}}
