A message can be pinned in any type of channel.
When a user pin a message, the pin is synchronized for everyone in the channel.

All pins can be seen for anyone in the channel.

In any channel, the user can search a message with filters. No more. Just that. You want more complicated explications ? I don't.

Direct Message is a channel type where only 2 users can communicate (In text or voice).
The identifier of a DM channel is the username of the receiver at his IP address (Eg. [email protected])
⚠️ The IP address can be changed (Refer to #4 )

DM channel other specifications :

• Users can send messages (Refer to #1 )
• Users can pin messages (Refer to #6 )
• Users can make call (Refer to Call issue)
• Users can edit/delete their own messages (Refer to #7)
• Users can search messages (Refer to #8)
• Users can load history of the channel if the other have it (Refer to History Sync issue)
• Can have E2E Encryption (Refer to E2E Encryption issue)

Some issues are not currently written.

If the receiver is disconnected, save the message in cache and wait until he's connected to send the message.

In function of the receiver's client, send/receive the message differently :

VBAN-M to VBAN-M

Send the full message with all infos. (Timestamp, channel (Can be DM or a group) and attachment meta)

VBAN-M to VBAN-CHAT

Send the message formatted with timestamp. (Eg. [7:54 PM] Hey my friend)
If the message is from a group, start the message with the group name. (Eg. The Best Group > [7:54 PM] Hey my friends)

VBAN-CHAT to VBAN-M

When the message is received, use the current date as timestamp, the channel is DM by default but when the message starts with a group name (Eg. The Best Group > Hey my friends !) use this group as channel.
⚠️ The spaces before and after the '>' are optional to parse the group name.

When a user with a known username connects to VBAN-M, VBAN-M asks the client of this user for his identifier (Refer to #5 ), if the identifier already exist in the database, VBAN-M will replace the old user by the new one by changing its IP address in the database.

⚠️ Subject to changes for security issues ⚠️

When the user change any info of himself (Status, commentary, profile picture, color...), send new infos to all connected friends.

⚠️ Only commentary and color can be sent to VBAN-CHAT (Using a ping)

The user identifier is a long text randomly set who can be exported/imported by the user.
The user identifier is made to identify you when you change your IP Address (Refer to #4 )
Other users can only conserve a hashed version of the identifier.

In a channel, all users can edit/delete their own messages.
When a message is edited/deleted, the user sends to other members of the channel that the message is deleted.
