Hello, I'm writing an IRCd. For this topic it doesn't really matter if you know much about IRC. Its a simple code style problem.
Quick overview of the problem:
No message may be longer than 512 characters
If the message is more, it must be broken into pieces
The NAMES reply sends all the nicknames of users on a channel, and quickly grows beyond 512 characters.
I currently concocted this marvelous piece of code, it works perfectly. However, its just not "ruby-like". This piece of code is more what you expect in some piece of C code.
# 11 is the number of all fixed characters combined in the reply
pre_length = 11 + servername.length + mynick.length + channel.name.length
list = [""]
i = 0
channel.nicks.each do |nick, client|
list[i+=1] = "" if list[i].length + nick.length + pre_length > 500
list[i] << "#{channel.mode_char(client)}#{client.nick} "
end
list.each { |l| send_numeric(RPL_NAMREPLY, channel.name, l.strip) }
send_numeric(RPL_ENDOFNAMES, channel.name)
So my question is, any ideas to do this more nicely?
PS. code has been slightly modified to make it easier to understand out-of-context
