An IRC bot is my "hello world" for network applications. I have a few in Python and one in newLISP.
The bot only supports connecting to a single server and channel.
The bot is started with three command line arguments:
serverthe IRC server to connect tochannelthe channel to joinnickthe nickname to use
The bot understands one command: msg.
The msg command takes two arguments:
- the recipient of the message
- the content (body) of the message
There are public and private messages. A public message is sent by calling the
msg command in a channel. A private message is sent by calling the msg
command in a private chat with the bot.
Messages have the attributes
- sender
- timestamp
- private
- body
When a message to a new recipient is sent, the bot creates a mailbox for that recipient. The mailbox is added to the repository of mailboxes.
The messages are stored until a user with the given recipient nick joins the
channel. Private messages are sent in a private chat, public ones in the
channel. They are sent in the format <timestamp> <sender> <body>. After a
message is sent, it is removed from the recipients mailbox. Empty mailboxes are
removed from the repository.
Messages are not sent immediately if the recipient is currently present in the channel.
There is a maximum number of messages per mailbox. When that limit is reached, no more messages to that recipient are accepted and the bot responds with an error message.
