Help:Extension:Translate/zh



翻译扩展为使用 MediaWiki 进行翻译工作提供了必要的特性增强. 它可以用于翻译页面内容、wiki 界面、甚至其他软件产品，像它用在translatewiki.net那样. 翻译扩展简单易用的翻译界面，并拥有可以从文本内容中分离出需要翻译的内容的结构，通过将内容分割为可管理的单元，仅显示可翻译文本给翻译者. 每个单元会自动更新变化，翻译人员通过特殊页面或wiki，可以立刻看到那里需要更新.

The Translate extension is used to translate the user interface of MediaWiki and other software projects at translatewiki.net by hundreds of translators every month. At userbase.kde.org it is used to translate almost a thousand content pages with user documentation. It is easy to start using the Translate extension, but at the same time it also scales up and provides advanced reporting, reviewing and workflow features.

功能


界面： 翻译扩展的主要特性是简单实用的翻译界面. 除了类似消息定义和文档这里必要的信息外，你还可以查看其他语言的翻译. 如果定义改变，你会看到该变更. 扩展包含一些内置检查，可以帮助发现常见错误，比如括号不成对、未使用变量. 根据设置，它还可以根据翻译记忆或机器翻译服务提供翻译建议，比如 Google 翻译、微软的 Bing 翻译器和 Apertium.

The usability of the translation interface is enhanced with JavaScript and AJAX. The backend provides WebAPIs than can be used in mobile interfaces or interfaces tailored to specific kind of content. It is also possible to export messages for translation in other off-line and on-line tools that accept the Gettext po file format.

Message groups and tasks: Many of the features are built around two basic concepts: message groups and tasks.

A message group represents a collection of messages. One content page would be one message group, where, in the simplest form, each paragraph would be one message in that group. Messages used in each MediaWiki extension form a message group on translatewiki.net – a few of the largest extensions have multiple groups. You can also make a group of groups, like All newsletters or All Translate extension messages. Many of the statistics and the tasks work on the message group basis.

The tasks, or in other words different listings of messages in a message group, facilitate different use cases. Normally a translator gets a list of all untranslated messages in a chosen message group, but there are tasks where you can review messages or just get a list of all messages, translated or not.



Reporting and statistics: The extension has extensive reporting features ranging from a view of untranslated messages across all message groups in a given language to lists of translators per language with their activity level.

Content translation: If you have ever tried to translate content in MediaWiki without any tools, you know it does not scale. The translated versions get out of date and there is no way to track changes to the master page, so there are many half-translated and outdated translations without a clear overview of the overall status. Translators often feel discouraged when they can not work with small manageable pieces of text. Translators don't find what to work on or what needs updating. The users also get confused by outdated information.

This is all solved with the Translate extension and its page translation feature. It adds a bit of overhead to the pages that need translation, but the benefits far outweigh this. Essentially you only need to mark the parts of the page that need translation. The extension then splits such parts into paragraph sized units and creates a message group for them. After that translators can use all the features described above. In addition you can easily add a language bar with the tag or have links automatically go to the user's preferred language version (only) when it exists, by using links of the form Special:MyLanguage/Pagename.

For more information see the tutorial How to set up a content page for translation and the in-depth documentation of the page translation feature.

Developers: The extension comes with built-in support for many common translation file formats, like Java properties and Gettext po files. It has an extensive set of tools, both in-wiki and on the command line, to efficiently import and export translations.

使用示例
You can translate almost anything with the Translate extension. Naturally there are specialized tools for translation of certain kind of content like video subtitles, that are better done with those tools, but in general Translate performs very well with any kind of text that can be split into messages with length ranging from one word up to one large paragraph. Longer messages become unwieldy to translate and are just harder to work with.

The three primary use cases that the Translate extension supports are content translation, local interface translation and software translation. All of them are covered in the following sections, with links to tutorials and to reference documentation or in-depth topical help where available. Of the three use cases the interface translation has been utilized the least.

内容翻译


Most wikis have content they would like to be available in multiple languages. Whether just a few or hundreds of pages, it doesn't matter. In order to prevent wasting translator's time, pages should be marked for translation only when they are reasonably stable. Each change that is made afterwards can affect tens or hundreds of old translations, and the time needed to update them adds up. Especially with volunteer translators, you should be aware of this aspect, and respect the time they spend making translations and updates, avoiding unnecessary work. If you use the Translate extension to translate pages, you are already well on your way to using the translator time available in the most effective and efficient way.

The way the Translate extension splits up a page into paragraph sized units does not leave too much freedom for translators to change the content. This is usually a good thing and is ideal where continuity and consistency of content across languages is desired. It can be worked around, but in principle this way of doing translations is not generally suitable, for example, for Wikipedia articles, which usually are totally independent of each other. Even if they originally start as a translation from a different language, they usually begin living their own independent life from the original version. With Translate, the original page is always the main version, and new content cannot be developed in translated versions.

With these limitations in mind there are still plenty of cases where this feature is a perfect match. Most, if not all, user documentation falls into this category as well as news-like content that does not change once written. If you have the Translate extension already installed and access rights configured, try creating a page and wrapping the whole text inside  and follow the links, or follow the tutorial How to prepare a page for translation.

多语言维基中的本地界面翻译
One thing almost every wiki has customized is the sidebar. It is possible to create a message group for the custom sidebar messages and also for other local interface customisations.

One interesting expansion is the multilingual pages or templates built with the magic word. The translatewiki.net main page and some Wikimedia Commons templates are good examples of this. The magic word is an alternative to the content translation feature and it is more suitable to mark-up heavy pages just like the translatewiki.net main page. Another nice feature is that the language of the page automatically follows the user interface language, so there is no need for a language bar, although you might want to have an interface language selector instead.

Setting this up is currently a bit more complicated than content translation and needs software configuration, but it is all covered in the tutorial How to make an interface message group.

软件翻译
The Translate extension is a good fit for translating software interface messages. At translatewiki.net, it is used to translate tens of software products from games to web applications. The Translate extension supports reading and updating translations from and to common formats used in web development including Java properties, Gettext and Yaml files.

Change tracking is also available for externally tracked files, because internally the extension uses a cached derivative version of the localisation files where the source text and its translations are stored, instead of using them directly in their original format. Translation administrators can either use the web interface or a command line interface to check new message definitions and "fuzzy" (request update of) translations when they need updating. This works regardless of the underlying file format or version control system (if any).

With simple command line tools, translation administrators can easily import even a large set of existing translations and with just one command they can export all translations in the correct format and in the correct directory structure. You can export directly to your VCS repository checkout, where you can easily commit changes and new files.
