Add Scrollback for joining users.

[zorchenhimer]

Add a scrollback with the last N messages in chat to send to joining users. The number of messages should be configurable.

Yep, seems to be an good idea.
Did you already though of a solution to keep the last N messages ?

• Maybe an in ram rolling stack ?

if i understand correctly a chat message is defined here:

MovieNight/common/chatdata.go

Line 86 in 9ba472b

type DataMessage struct {

Therefore it should be rather easy to implement a rolling stack with a fixed length to enable scrollback.

I bet the 'bigest' problem isn't the stack but handling the new chat user and send just to him the stack content.

Nah, that should be pretty straight forward. A bunch of (hidden) messages are already sent to the client during the join process. Sending the scrollback would just happen after all that. I suppose it could be a new hidden message type so it could be formatted differently or something (eg, greyed out), but that's not exactly necessary.
