Localisation/it

Localizzazione è in generale il processo che fornisce un software con una interfaccia utente (GUI) multilingua.

In FreeCAD è possibile impostare la lingua dell'interfaccia utente in Modifica → Preferenze → Applicazione.

FreeCAD utilizza Qt per abilitare il supporto di più lingue. Sui sistemi Unix / Linux, FreeCAD utilizza le impostazioni locali di default del sistema.

Helping to translate FreeCAD
One of the very important things you can do for FreeCAD if you are not a programmer, is to help to translate the program in your language. To do so is now easier than ever, with the use of the Crowdin collaborative on-line translation system.

How to Translate

 * Go to the FreeCAD translation project page on Crowdin;
 * Login by creating a new profile, or using a third-party account like your GMail address;
 * Click on the language you wish to work on;
 * Start translating by clicking on the Translate button next to one of the files. For example, FreeCAD.ts contains the text strings for the FreeCAD main GUI.
 * You can vote for existing translations, or you can create your own.

Note: If you are actively taking part in translating FreeCAD and want to be informed before next release is ready to be launched, so there is time to review your translation, please subscribe to this issue: http://www.freecadweb.org/tracker/view.php?id=137

Translating with Qt-Linguist (old way)
The following information doesn't need to be used anymore and will likely become obsolete. It is being kept here so that programmers may familiarize themselves with how it works.


 * Open all of the language folders of FreeCAD shown below
 * Verify that a .ts file with your language code doesn't exist ("fr" for french, "de" for german, etc...)
 * If it exists, you can download that file, if you want to modify/review/better the translation (click the file, then download)
 * If it doesn't exist, download the .ts file without language code (or any other .ts available, it will work too)
 * Rename that file with your language code
 * Open it with the Qt-Linguist program
 * Start translating (Qt Linguist is very easy to use)
 * Once it's completely done, save your file
 * send the files to us so we can include them in the freecad source code so they benefit other users too.

Prerequisites
To localise your application module your need to helpers that come with Qt. You can download them from the Trolltech-Website, but they are also contained in the LibPack:
 * qmake: Generates project files
 * lupdate: Extracts or updates the original texts in your project by scanning the source code
 * Qt-Linguist: The Qt-Linguist is very easy to use and helps you translating with nice features like a phrase book for common sentences.

Project Setup
To start the localisation of your project go to the GUI-Part of you module and type on the command line: This scans your project directory for files containing text strings and creates a project file like the following example:

You can manually add files here. The section TRANSLATIONS contains a list of files with the translation for each language. In the above example MyMod_de.ts is the german translation.

Now you need to run lupdate to extract all string literals in your GUI. Running lupdate after changes in the source code is allways safe since it never deletes strings from your translations files. It only adds new strings.

Now you need to add the .ts-files to your VisualStudio project. Specifiy the following custom build method for them: Note: Enter this in one command line, the line break is only for layout purpose.

By compiling the .ts-file of the above example, a header file MyMod_de.h is created. The best place to include this is in AppGui.cpp. In our example this would be AppMyModGui.cpp. There you add the line to publish your translation in the application.

Setting up python files for translation
To ease localization for the py files you can use the tool "pylupdate4" which accepts one or more py files. With the -ts option you can prepare/update one or more .ts files. For instance to prepare a .ts file for French simply enter into the command line: the pylupdate tool will scan your .py files for translate or tr functions and create a YourModule_fr.ts file. That file can the be translated with QLinguist and a YourModule_fr.qm file produced from QLinguist or with the command Beware that the pylupdate4 tool is not very good at recognizing translate functions, they need to be formatted very specifically ( see the Draft module files for examples). Inside your file, you can then setup a translator like this (after loading your QApplication but BEFORE creating any qt widget): Optionally, you can also create the file XML Draft.qrc with this content: and running pyrcc4 Draft.qrc -o qrc_Draft.py creates a big Python containing all resources. BTW this approach also works to put icon files in one resource file

Translating the wiki
This wiki is hosting a lot of contents, the majority of which build up the manual. You can browse the documentation starting from the Main Page, or have a look at the User's manual Online Help Toc.

Translation plugin
When the Wiki moved away from SourceForge, Yorik installed a Translation plugin which allows to ease translations between pages. For example, the page title can now be translated. Other advantages of the Translation plugin are that it keeps track of translations, notifies if the original page has been updated, and maintains translations in sync with the original English page.

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

To quickly get started on preparing a page for translation and activating the plugin, please read the Page translation example.

To see an example of how the Translation tool works once the translation plugin is activated on a page, you can visit the Main Page. You will see a new language menu bar at the bottom. It is automatically generated. Click for instance on the German link, it will get you to Main Page/de. Right under the title, you can read "This page is a translated version of a page Main Page and the translation is xx% complete." (xx being the actual percentage of translation). Click on the "translated version" link to start translation, or to update or correct the existing translation.

You will notice that you cannot directly edit a page anymore once it's been marked as a translation. You have to go through the translation utility.

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

'''REMARK: The first time you switch a page to the new translation system, it looses all its old 'manual' translations. To recover the translation, you need to open an earlier version from the history, and copy/paste manually the paragraphs to the new translation system.'''

Remark: to be able to translate in the wiki, you must of course gain wiki edit permission.

Old translation instructions
These instructions are for historical background only, while the pages are being passed to the new translation plugin.

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

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.

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 "Bienvenue sur l'aide en ligne" redirects to Online Help Startpage/fr, and the page "Fonctionnalités" redirects to Feature list/fr.
 * The page About FreeCAD/fr is the page with content
 * The page À propos de FreeCAD contains this code:
 * 1) REDIRECT About FreeCAD/fr
 * In the About FreeCAD/fr page, the Docnav code will look like this:

If you are unsure how to proceed, don't hesitate to ask for help in the forum.
