Allow tilde in nicks

[hexjelly]

Ran into an issue with the message handler returning the "from" variable (nick) as undefined. Noticed the regex does not allow the tilde characters in nicks.

As far as I know and what RFC 2812 specifies, tilde () is not a valid character for a nickname.
Is this possibly an issue with prefixchars (&@%+) on nicknames in a channel?

[hexjelly]

Maybe it's not too prevalent then, I'm not super familiar with the RFC or what server specific stuff there are. I just know on the network I'm using it's allowed; IRCNet.

I agree with @del6597 on this one. Are you sure the ~ character isn't just the prefix of the nick?

@hexjelly Can you include the output of the error you are seeing?

[hexjelly]

Yes I am certain. There is no error, you will just get undefined if you try to use the returned 'message.nick' variable anywhere, as the regex won't match. So anything that uses the parseMessage function. You can follow the RFC, but at least the module will not work properly for anyone that uses the IRCNet network, well for nicks with a tilde in them anyway :) Again, maybe it's the only network out there that doesn't follow the RFC's nick restrictions for all I know though. Though unlikely?

Still, would it not be saner to just have a more open regex to match anything followed by !@ as the source, and let the server decide what it can/will use instead?

I just took a look at IRCNets software changelogs.

This is version 2.11.1 of the IRC software.
===============================================================================

New features in 2.11.1:
    * Clients can use '~' char in nicknames.

@del6597 Thanks for finding that.

@hexjelly You're right. It won't hurt anything to add it.
