Общ преглед

Локализация, общо взето, е процесът на снабдяване на даден софтуер с потребителски интерфейс на различни езици. Във FreeCAD можете да зададете езика на потребителския интерфейс през Редактиране → Предпочитания → General. FreeCAD използва Qt за да поддържа потребителски интерфейс на множество езици. На системи Unix/Linux, FreeCAD използва по подразбиране потребителските регионални настройки на вашата система.

Помагане за превеждане на FreeCAD

Едно от много важните неща, с които потребителите могат да допринесат за FreeCAD (ако например нямат умения за програмиране), е да помогнат за превода на различните му аспекти (изходен код, уики, уебсайт, документация и др.) на друг език. Ето начините да направите това.

Превеждане на програмния код на FreeCAD

FreeCAD използва система за съвместно превеждане онлайн на трета страна, наречена Crowdin.

Той е платен софтуер, но безплатен за FOSS проекти. По-долу са дадени инструкции как да го използвате:

Ако активно участвате в превода на FreeCAD и искате да бъдете информирани, преди следващото издание да е готово за стартиране, за да има време да прегледате превода си, моля, присъединете се към един от екипите за превод на Crowdin FreeCAD.

Note: Подробности за това как да използвате crowdin можете да намерите на страницата Crowdin Administration.

Превод на външни работни маси

Посетете Превеждане на външни работни маси.

Предпочитания за преводачи на FreeCAD

Започвайки от FreeCAD 0.20, следните променливи могат да бъдат добавени ръчно към раздела BaseApp/Preferences/General на файла user.cfg, за да помогнат с разработването на нови преводи:

AdditionalLanguageDomainEntries - за напълно нови езици за FreeCAD, които още не се поддържат от програмния код, можете да използвате това потребителско предпочитание, за да добавите към списъка на наличните езици. Форматът за езици е "Language Name"="code"; например: 

<FCText Name="AdditionalLanguageDomainEntries">"Esperanto"="eo";"French"="fr";</FCText>

AdditionalTranslationsDirectory - добавяне на допълнителна директория към FreeCAD да търси *.qm файлове. Това място ще има приоритет прад $userAppDataDir/translations и $resourceDir/translations. Например: 

<FCText Name="AdditionalTranslationsDirectory">C:/Users/FreeCADUser/TestTranslations</FCText>

Превеждане на Укито на FreeCAD

Това уики е хранилището за много съдържание, по-голямата част от което изгражда ръководството за ползване. Можете да прегледате документацията, започвайки от Главна страница, или да разгледате ръководството на потребителя Online Help Toc.

За да превеждате уикито, трябва да имате разрешения за редактиране; вижте How can I get edit permission on the wiki?.

You should also have enough knowledge of wiki markup and follow the general styling guidelines described on WikiPages.

Mediawiki Translation Extension

When the wiki moved away from SourceForge, Yorik installed MediaWiki's Translation extension which facilitates translating pages. Advantages of the translation extension are that the page title can now be translated, it keeps track of translations, it notifies if the original page has been updated, and it maintains translations in sync with the original English page.

The tool is documented in Help:Extension:Translate, and is part of MediaWiki Language Extension Bundle.

To quickly get started on preparing a page for translation, please read the Page translation example. A pair of tags need to surround the entire page to activate the translation system: 

<translate> ... </translate>

The page also needs to be marked for translation.

To see an example of how the translation tool works, visit the Main Page. You will see an automatically generated language bar at the top. Click on Deutsch (German), it will get you to Main Page/de. Right under the title, "Hauptseite" (in English "Main Page"), you can read This page is a translated version of the page Main Page and the translation is XX% complete, XX being the current percentage of translation. Click on "Translate" at the top of the page to start the translation utility to update, correct and review the existing translation.

If you go to Main Page, you will notice that you cannot edit the page directly anymore by clicking the [Edit] tags, and the top link "Edit" has been substituted by the "Translate" link that opens the translation utility.

When adding new content, the English page should be created first, then translated into another language. If someone wants to change or add content in a page, the English page should be modified first.

If you are unsure on how to proceed with the translations, don't hesitate to ask for help in the Development → Wiki subforum or in the specific language subforum in the FreeCAD forum.

Important notes

Every wiki user that has "Editor" permissions is able to launch the translate utility to write, save and review translations.

However, only users with "Administrator" permissions are able to mark pages for translation. A page that is not marked for translation won't make use of the translation extension and won't be correctly synchronized to the English information.

The left sidebar is also translatable, but only Administrators can modify this element of the site. Please follow the dedicated instructions on Localisation Sidebar.

The first time you switch a page to the new translation system, it loses all its old "manual" translations. To recover a translation, you should save an offline copy of the old text before the switch. Then you can use this old translated text to fill in the translation units in the new system. You can also open an earlier version from the history, and get the old text in this way. This has to be done for every language that had a translated page.

Translate the FreeCAD documentation

As per general consensus, the reference page in the wiki is the English page, which should be created first. If you want to change or add content to a page, you should do it to the English page first, and only once the update is completed, port the modification to the translated page.

Old translation instructions

These instructions are for historical background only. Translations should use the new system with the #Mediawiki Translation Extension described above.

So the first step is to check if the manual translation has already been started for your language (look in the left sidebar, under "manual").
If not, head to the forum and say that you want to start a new translation, we'll create the basic setup for the language you want to work on.
You must then gain wiki edit permission.
If your language is already listed, see what pages are still missing a translation (they will be listed in red). The technique is simple: go into a red page, and copy/paste the contents of the corresponding English page, and start translating.
Do not forget to include all the tags and templates from the original English page. Some of those templates will have an equivalent in your language (for example, there is a French Docnav template called Docnav/fr). You should use a slash and your language code in almost all the links. Look at other already translated pages to see how they did it.
Add a slash and your language code in the categories, like [[Category:Developer Documentation/fr]]
And if you are unsure, head to the forums and ask people to check what you did and tell you if it's right or not.
Four templates are commonly used in manual pages. These 4 templates have localized versions (Template:Docnav/fr, Template:fr, etc...)

  • Template:GuiCommand : is the Gui Command information block in upper-right of command documentation.
  • Template:Docnav : it is the navigation bar at the bottom of the pages, showing previous and next pages.
  • Template:Userdocnavi : gives direct links to the main base pages

Page Naming Convention
Please take note that, due to limitations in the Sourceforge implementation of the MediaWiki engine, we require that your pages all keep their original English counterpart's name, appending a slash and your language code. For example, the translated page for About FreeCAD should be About Freecad/es for Spanish, About FreeCAD/pl for polish, etc. The reason is simple: so that if translators go away, the wiki's administrators, who do not speak all languages, will know what these pages are for. This will facilitate maintenance and avoid lost pages.
If you want the Docnav template to show linked pages in your language, you can use redirect pages. They are basically shortcut links to the actual page. Here is an example with the French page for About FreeCAD.

  • The page About FreeCAD/fr is the page with content
  • The page À propos de FreeCAD contains this code:
#REDIRECT [[About_FreeCAD/fr]]
  • In the About FreeCAD/fr page, the Docnav code will look like this:
{{docnav/fr|[[Online_Help_Startpage/fr|Bienvenue dans l'aide en ligne de FreeCAD]]|[[Feature_list/fr|Fonctionnalités]]}}

The page "Bienvenue dans l'aide en ligne de FreeCAD" redirects to Online_Help_Startpage/fr, and the page "Fonctionnalités" redirects to Feature_list/fr.

Translate the FreeCAD website

Translation of the FreeCAD website is now done through Crowdin. The file is named homepage.po.

Development - How to Add Localisation

This section is for developers who want to add localisation to their code.

Preparing your FreeCAD/master modules for translation

These are the parts to the FreeCAD translation process:

  • extract text strings from source code into *.ts files
  • load *.ts files into FreeCAD Crowdin.
  • translation of strings within Crowdin
  • extract modified/new *.ts files from Crowdin
  • convert *.ts files into *.qm files and update each module's *.qrc file
  • update FreeCAD master

All of the above steps are performed by the "translation scripts" which are run by an administrator periodically.

Preparing your module for translation is quite easy. First, you need to ensure that you have a "translations" directory in myModule/Gui/Resources. Then open a terminal window (or Windows/OSX equivalent) in your "translations" directory and enter the following command: 

lupdate -ts myModule.ts

This creates an empty translation file. Once this is done, you need to ensure that the translation scripts are updated as in this pull request.

Everything after this is automatic as far as a developer is concerned. The administrator will extract the text strings, the translators will translate them, then the administrator will extract the translations and update FreeCAD/master.

Preparing your 3rd party module or macro for translation

3rd party modules or macros are translated in much the same fashion, except that you must do some of the work yourself. This forum discussion describes the details.

Update: see Translating an external workbench

Automating Crowdin Translation Updates

Currently FreeCAD maintainers use the Crowdin API via Crowdin Scripts to pull and push translations in to Crowdin and back in to the Github repo. The Crowdin API gives FreeCAD maintainers the ability to automate aspects of the project's translation workflow, for more info refer to the Crowdin API documentation.

Scripting

See also: FreeCAD Scripting Basics.

To get a dictionary with the languages the FreeCAD interface supports, use the supportedLocales method of the FreeCADGui module. 

locales = FreeCADGui.supportedLocales()

After execution locales will contain: 

{'English': 'en', 'Afrikaans': 'af', 'Arabic': 'ar', 'Basque': 'eu', 'Catalan': 'ca', 'Chinese Simplified': 'zh-CN', 'Chinese Traditional': 'zh-TW', 'Croatian': 'hr', 'Czech': 'cs', 'Dutch': 'nl', 'Filipino': 'fil', 'Finnish': 'fi', 'French': 'fr', 'Galician': 'gl', 'German': 'de', 'Hungarian': 'hu', 'Indonesian': 'id', 'Italian': 'it', 'Japanese': 'ja', 'Kabyle': 'kab', 'Korean': 'ko', 'Lithuanian': 'lt', 'Norwegian': 'no', 'Polish': 'pl', 'Portuguese': 'pt-PT', 'Portuguese, Brazilian': 'pt-BR', 'Romanian': 'ro', 'Russian': 'ru', 'Slovak': 'sk', 'Slovenian': 'sl', 'Spanish': 'es-ES', 'Swedish': 'sv-SE', 'Turkish': 'tr', 'Ukrainian': 'uk', 'Valencian': 'val-ES', 'Vietnamese': 'vi'}

To get the current interface language use the getLocale method of the same module: 

locale = FreeCADGui.getLocale()

If the current language is English locale will contain: 

'English'

To get the corresponding language code you can use use: 

locale = FreeCADGui.supportedLocales()[Gui.getLocale()]

If the current language is English the result will be: 

'en'

To set the current interface language use the setLocale method of the same module. You can specify the language or the language code: 

FreeCADGui.setLocale('Russian')
FreeCADGui.setLocale('ru')
