The "official" way of translating WebExtensions content is the
which requires to define a key for each portion of text to translate.
This can be seen as brain consuming, especially in the case of a big web page, with lots of text parts, like a form. It’s the case of Meta-Press.es main interface, but also for its preferences, like a lot of other WebExtensions.
In order to get close of the standard GNU
gettext way of translating
programs, I decided to use Guillaume Potier’s
gettext.js and to code the
helper functions that was missing to:
collect texts needing translation (
automatically maintain a
template.jsonand corresponding translations,
and translate texts of HTML pages at loading time.
Now Meta-Press.es is available in English, French, Spanish and Esperanto !
To contribute a new language, you have just to fill the blanks in the templace.json file of the Meta-Press.es project, and create a pull-request (or send it via email).
If you’re looking for a simple way of translation / internationalisation for your Firefox Addon project (or a least your option page), I shared the dedicated code as a separate project in the gettext_html_auto.js repository, along with some documentation. You would be welcome to use it.
With month_nb, it’s the 2nd side project made for Meta-Press.es.
