WebIssues uses the Qt Linguist application for translating the Desktop Client and the Web Client applications. In both cases the process looks very similar.

Translation Files

Translators operate mainly on the .ts files which are located in translations directory in case of the Desktop Client and common/data/translations directory in case of the Web Client. There is one .ts file for each language, for example webissues_pl.ts for Polish and webissues_pt_BR.ts for Brazilian Portuguese translation.

In order to translate phrases in the .ts file you will need the Qt Linguist application which is shipped with the Qt Framework and available for all platforms including Linux, Windows and Mac OS. The detailed user guide can be found in the Qt documentation.

If you are using Windows and don't want to download and install the entire Qt framework, you can use the stand-alone version of Qt Linguist: Linguist.zip.

Translation Process

A week or two before a planned release a "string freeze" is announced, meaning that code cannot be added or modified if that changes any user visible strings. All .ts files are updated to reflect changes in the code made since the previous version and that causes some new untranslated strings to appear. The updated .ts files are sent to the translators responsible for each language and they should send back the completed files. Finally, binary files are generated from the .ts files and included in the release packages.

Adding a New Language

New translations can be created by copying and renaming the webissues_untranslated.ts file. In addition, the locale.ini file must be updated with the code and name of the language. In case of the Desktop Client, this file is located in the translations directory. In case of the Web Client, the file is located in common/data and besides the list of languages it also contains culture information. A section with the same name as the language code must be created, containing the format of numbers, dates and times and the first day of week (counting Sunday as 0) for that culture. Available formats are listed in the formats.ini file.

Testing Translations

When testing translation with a development version, it must be downloaded from the SVN repository and compiled (in case of the Desktop Client) or installed (in case of the Web Client).

Standard lupdate and lrelease tools from Qt Framework are used to update and compile the translation files for the Desktop Client. For testing purposes translators can manually release the completed translation files (this can be done directly using the Qt Linguist).

A special set of tools, called lupdatephp and lreleasephp, was created to support translation of the Web Client application. They work almost the same as their standard counterparts, but they understand the coding conventions used in the PHP application and use a different format of the compiled file (which is more efficient to use with PHP that the standard binary format). These tools can be found in the trunk/tools/linguistphp directory in the SVN repository. You can also download Windows binaries if you don't want to compile them manually: LinguistPhp.zip.
