Formatting of socket

IRC is quite a hassle to understand, so the first thing to know about the protocol is the socket and server/client.

It's quite simple on client-side, but server-side has to supply more info:

↗️ PRIVMSG target :content
🔀 :nick!ident@host PRIVMSG target :content
^ Replace nick, ident, host, & target with the respective values described.
↗️ COMMAND arg :content
↙️ :server RPL nick data :content
^ Replace nick with the nickname of the current connection.

Caution

If the command has content, the colon MUST be included, and is at the beginning of the content, not the end of the command/args.

↗️ COMMAND: content
↙️ :server 421 nick COMMAND: :Unknown command
^ Replace nick with the nickname of the current connection.
