Changes your nickname.
/nick new-nick
Note:
- Valid nickname characters are as follows: 0-9a-z\[]^_`{|}-
- A nickname must also not begin with a numeric or a hyphen (-).
- Some ircd reserve single character nicknames for service bots, QuakeNet is an example of this.
Here is an example to check if %nick is a valid nickname or not:
var %nick = /V/alid if ($regex(%nick,%i,/^([a-z\Q\|[]^_`{}-\E](-\w\Q\|[]^_`{}-\E)*)/i)) { echo -ag $regml(1) is a valid nickname! } else { echo -ag %nick is not a valid nickname! }
Note: The above example, if you feed it with \Valid!nvalid, it would return it as a valid nickname, although the only valid part of the nick is \Valid. If you type /nick \Valid!nvalid the ircd would trim the nick to \Valid, this is why in the echo of a valid nickname we use $regml(1) instead of %nick, this is a back reference to the valid nickname captured.
If you also want to check that the nickname is atleast two characters long you can replace the * with a + as it will make sure that the second exists:
/^([a-z\Q\|[]^_`{}-\E](-\w\Q\|[]^_`{}-\E)+)/i
The example below will only match if the whole nickname is valid, so it won't truncate the nickname:
/^([a-z\Q\|[]^_`{}-\E](-\w\Q\|[]^_`{}-\E)*)$/i
