How should I organise translations of plugins?

odelaune

I am wondering what is the best way/the most clever way to organise the translation of plugins?

There are two options:

option 1: one single file with the translations of the main application and the translations of all the plugins
option 2: one file with the translations of the main application and one translation file per plugin

The option 2 seems more logical to me, because when I create new plugins for my main application, I ship the translation of that plugin inside my plugin. However, Qt Creator only uses one translation file for Qt Creator itself and all its plugins. I do not understand why this logic is used.

So if the option 1 is preferred, how to create only one big TS file?
My project has a source directory for the main application and the plugins sources are located in subdirectories.

If the option 2 is preferred, how to write the plugin CMakeLists to handle the translations? Is there something specific with the plugin translations?

Because all plugins are in the same git repo and not distributed indepentendly so no need to fiddle around with more than one translation file.

Is there something specific with the plugin translations?

No. You just need a schema to know which translation file belongs to which plugin.

Ok, here is my progress. Here the CMakeLists.txt of my plugin

set(TS_FILES
    i18n/MyPlugin_en.ts
    i18n/MyPlugin_fr.ts
)

# Adding translations
qt_add_translations(MyPlugin
TS_FILES ${TS_FILES}
LUPDATE_OPTIONS -no-obsolete
OUTPUT QM_FILES)

install(FILES ${qm_files} DESTINATION ${CMAKE_INSTALL_BINDIR})

Initially the MyPlugin_*.ts files are empty, so I need to go to the i18n folder and to run lupdate there. Then I translate strings.

Finally, I compile. There is no error but the strings of MyPlugin are not translated.

Any idea about what is missing?
