How to add languages

Explanation

There are two different language code formats:

• Language Code specifies the base language. For example: en
• ISO Country Code is defined as language-COUNTRY. For example: en-US

datahub.io has a table for all languages.

All language-COUNTRY formats should inherit from the base language. See de and de-DE for example.

Adding a new language

1. Fork this repo and clone your fork
2. Create your own branch named add-i18n-LANG. Example

git switch -c add-i18n-en

3. Go to frontend/translations/ and create a new file called LANG.json. Example: en.json
4. Do all the translations for the new language. (Take a look at existing translations and copy where needed)
5. Add your new locale to the project.inlang settings.
6. Open frontend/src/lib/stores/locale.ts, import your new locale from date-fns and add it to the switch statement. Preferably in alphabetical order.
7. Add the corresponding flag emoji in the account page
8. Run format and lint:

pnpm run format
pnpm run lint

8. If no warnings/errors show up, commit, push and create a pull request.
