@marcelklehr Do the old APIs still work or do we need to move this for 30?

[marcelklehr]

The old APIs still work, but we're moving most apps to the TaskProcessing API now, so the old APIs will not be used by most providers anymore.

[juliushaertl]

Do you think we need to keep both APIs in parallel then or just just migrating to the new one fine?

[marcelklehr]

I would just migrate to the new one directly.

[juliushaertl]

• Migrate the FakeTranslationProvider to the new task api as it is used by our cypress tests
• Migrate text initial state for translations to new task processing API
• Migrate Translate.vue component to use task procesing API when doing the API call to translate

Notes from chat with Marcel:

• So, the Translate task type defines input and output language slots: https://github.com/nextcloud/server/blob/master/lib/public/TaskProcessing/TaskTypes/TextToTextTranslate.php#L69-L85
• these are defined as enums, the value for which is defined by the provider
• getAvailableTaskTypes contains the possible values in the key inputShapeEnumValues: https://github.com/nextcloud/server/blob/master/lib/public/TaskProcessing/IManager.php#L48-L52
• integration openai implements a translate provider for example: https://github.com/nextcloud/integration_openai/blob/main/lib/TaskProcessing/TranslateProvider.php
• translate2 app will implement this
• translate app not
• deepl/libretranslate need scheduling

Hey there,

The testing app now has a task processing translation provider: OCA\Testing\TaskProcessing\FakeTranslateProvider
