Filter filter:activity-pub.activity.context.build.result: missing object type as parameter

[JohnXLivingston]

Describe the problem to be solved

When using filter:activity-pub.video.json-ld.build.result to add some specific data in the ActivityPub video object, the documentation recommands using filter:activity-pub.activity.context.build.result to update the JSON-LD context.

filter:activity-pub.video.json-ld.build.result is specific to Video objects, but filter:activity-pub.activity.context.build.result is called for all object types (Video, Comment, Playlist, ...).

There is no easy way to know which object type we are manipulating, so we can't choose to add some specific data only for Video object.

Describe the solution you would like

The hook function should receive an additional type parameter:

PeerTube/server/lib/activitypub/context.ts

Lines 182 to 189 in 8ef8660

	async function getContextData (type: ContextType) {
	const contextData = await Hooks.wrapObject(
	contextStore[type],
	'filter:activity-pub.activity.context.build.result'
	)
	return { '@context': contextData }
	}

Should become something like:

async function getContextData (type: ContextType) {
  const contextData = await Hooks.wrapObject(
    contextStore[type],
    'filter:activity-pub.activity.context.build.result',
    { type }
  )

  return { '@context': contextData }
}
