User and room mentions
This module allows users to mention other users and rooms within a room message. This is achieved by including a Matrix URI in the HTML body of an m.room.message event. This module does not have any server-specific behaviour to it.
Mentions apply only to m.room.message events where the msgtype is
m.text, m.emote, or m.notice. The format for the event must be
org.matrix.custom.html and therefore requires a formatted_body.
To make a mention, reference the entity being mentioned in the
formatted_body using an anchor, like so:
{
"body": "Hello Alice!",
"msgtype": "m.text",
"format": "org.matrix.custom.html",
"formatted_body": "Hello <a href='https://matrix.to/#/@alice:example.org'>Alice</a>!"
}
Client behaviour
In addition to using the appropriate Matrix URI for the mention,
clients should use the following guidelines when making mentions in
events to be sent:
- When mentioning users, use the user's potentially ambiguous display name for the anchor's text. If the user does not have a display name, use the user's ID.
- When mentioning rooms, use the canonical alias for the room. If the room does not have a canonical alias, prefer one of the aliases listed on the room. If no alias can be found, fall back to the room ID. In all cases, use the alias/room ID being linked to as the anchor's text.
The text component of the anchor should be used in the event's body
where the mention would normally be represented, as shown in the example
above.
Clients should display mentions differently from other elements. For example, this may be done by changing the background color of the mention to indicate that it is different from a normal link.
If the current user is mentioned in a message (either by a mention as defined in this module or by a push rule), the client should show that mention differently from other mentions, such as by using a red background color to signify to the user that they were mentioned.
When clicked, the mention should navigate the user to the appropriate user or room information.
{{% boxes/note %}} Similar to legacy matrix.to URLs, groups used to be representable by mentions. They follow a similar format to room mentions, though using the group ID in both the link and anchor text. {{% /boxes/note %}}
