version

Synopsis

/ctcp <target> version

Description

Ask another client which IRC client and version it is using. The returned information can be customized or falsified by that client or its scripts; it is not a verified software identification. A client may disable or omit the responder, so no reply is guaranteed.

<target> is normally a nickname. The ctcp command also accepts a channel or * for the current channel, where multiple clients may respond. There are no version-specific options or required arguments. In ordinary use, the request travels in an IRC privmsg and the reply in a CTCP notice. Delivery, filtering, and errors depend on the server and destination.

EPIC6 response behavior

The responder is supplied by script/ctcp, loaded by script/builtins, rather than by a C built-in handler. A setup that does not load it needs /load ctcp to install the handler.

The supplied script ignores additional request arguments and constructs this reply:

ircII <client-version> - <client-information>

<client-version> is $J, the client's compiled version name. <client-information> is the current client_information setting, whose default comes from the build's IRCII_COMMENT. The handler does not independently query or append the operating system name or version; such information appears only if included in the configured text or a customized handler.

Replies normally pass through on ctcp_reply and display as CTCP VERSION reply from sender: reply-text unless scripts suppress or customize display. Request hooks or deactivating the registered CTCP can prevent responding. Automatic replies are subject to no_ctcp_flood reply throttling. Encoding conversion and IRC message-space limits can alter or truncate the transmitted text.

Examples

/ctcp john version

Request John's client identification. Customize the final part of your own supplied responder's reply with:

/set client_information Running my own scripts.
