Guidelines

The IRC protocol is a text-based protocol, with the simplest client being any socket program capable of connecting to the server.

The IRC network is like a Spanning tree, where each server is a central node ofr the rest the network it sees.


  • Client

A client is anything connecting to a server that is not another server.

    * Nickname (Unique & MAX 9 Chars);
    * Username;
    * Hostname;
  • Channel

A channel is a named group of one or more clients which will all receive messages addressed to that channel.

    * First Client to join = Channel Operator = Creates the Channel;
    * Channel Endes when the last Client leaves;
    * Messages are sent to all Clients in the Channel;
    * Channel's Name begin with '&' or '#' and MAX of 200 chars.
    * Channel's Name may NOT contain spaces(' '). control G(^G or ASCII 7), or commas (',');
  • Operators

Operators are a special type od clients, with more privilegies. This aims to keep the order in an IRC network.

Channel Operators (also referred to as a chop or chanop and identified by the '@' symbol) have special COMMANDS:

    KICK    - Eject a client from the channel
    MODE    - Change the channel's mode

            > About -p and -s : "Both can’t be set together. And uppon setting one mode, the other one is automatically unset." 
    
    INVITE  - Invite a client to an invite-only channel (mode +i)
    TOPIC   - Change the channel topic in a mode +t channel

  • Messages

      * Comunication is essentially asynchronous (meaning, Clients should not wait for a Reply from the Server.)
  * Messages are always terminated with Carriage Return - Line Feed and they should NOT exceed 512 chars.
  * Server must parse the entire message and return appropriate errors.
  * All Parameters must be check for validity.

    Divided in 3 Main Parts:

    1. Prefix (Opcional)

      • Indicated using a colon (':') (ex: ':isousa') *No whitespaces between the ':' and the prefix.
      • Used to indicate the origin of the message.
      • If there is no prefix, Server will assume it is originated from the connection it was received.
      • If the source can't be found (ex: prefix dont match any user) or if the source is different than the link it arrived from, the message should be ignored.

    2. Command

      • Valid IRC command or a 3 digit number.

    3. Command Parameters (MAX 15)
