Hello,
As you may know, I’m the livechat plugin maintainer.
The plugin is translated in several languages, but there are still a lot of missing translations.
Until today, translations were made directly in the project repository.
This was not easy for non-developpers, and required a github account.
But, big change, Framasoft accepted to host the plugin translations on their Weblate instance!
This means that users that already have accounts (for example users helping to translate Peertube) can now easily help to translate the plugin.
And of course, this mean that anyone, including non-developers people, will be able to help.
We can now also easily see the current translation state: https://weblate.framasoft.org/widgets/peertube-livechat/-/multi-auto.svg (this picture only shows languages that have at least one translation, there are other available locales). You can also just check the project.
If you want to help, you can check the livechat Weblate project!
I wrote a documentation: Translate :: Peertube plugin livechat documentation . It was written in a hastily, I hope it’s understable.
Don’t hesitate to ask for help if you encounter any issue. And thanks to all people that will help to translate it
