Add support for changing app language

[cfoellmann]

Have you thought about providing translation support?

I am looking for an rss app for our staff and would be happy to provide German and maybe polish translations

Yes! Thank you. Right now you can find the English version of the strings here. What I would recommend doing is, creating a Google Sheet with key and translated string for the language. I can then create the Kotlin class.

Or if you are comfortable with forking and cloning the project, and creating new Kotlin classes, that would be great as well. Here is the process.

1. Edit the Locales object in TwineStrings.kt to add a new locale ISO tag. In your case de for Germany and pl for Polish.

object Locales {
  const val EN = "en"
  const val DE = "de"
  // more locales
}

2. Then create a new file under the same package as EnTwineStrings, you just have to attach the ISO prefix to the TwineStrings name. So, we will have DeTwineStrings.

3. In that file create a new variable called DeTwineStrings and initialise the TwineStrings data class to add your translations.

@LyricistStrings(languageTag = Locales.DE, default = false)
val DeTwineStrings = TwineStrings(
  // translations
)

4. Run ./gradlew spotlessApply task before raising a PR to make sure code style checks pass.

If this process is a lot, feel free to fallback to just providing me with the Google Sheet, and I can make these changes.

I was able to raise a PR for addition of a german translation

I would add support for other languages at the weekend
