Send CTCP commands with The Lounge

CTCP commands are special messages that can be sent to a channel or other clients. Servers do not interpret their content, as it is the role of the receiving client to do so.

In fact, you might have used a CTCP command without knowing it. In The Lounge and most IRC clients, sending /me says hello world actually sends the CTCP ACTION command with says hello world as a parameter. It is then interpreted by clients to display it in the way you are familiar with.

With The Lounge, you can send a CTCP command by sending messages starting with /ctcp. If you are sending requests to other users using The Lounge, here are the currently implemented ones:

• /ctcp <nick> version returns something along the lines of VERSION thelounge v3.0.0 -- https://thelounge.chat/
• /ctcp <nick> source returns SOURCE git+https://github.com/thelounge/thelounge.git
• /ctcp <nick> ping foo returns PING foo

The Lounge does not support all CTCP commands, such as DCC.

When querying other users, know that their clients might inform them that you are requesting information about them, in the form of a notification or sound.
