type IrcMessage = Message ByteString

Messages

data Event a

A decoded IRC message + source.

Constructors

Event

Fields

• _raw :: ByteString

  The message as a bytestring.

• _source :: Source a

  The source of the message (user, channel, or server).

• _message :: Message a

  The decoded message. This will never be a RawMsg.

Instances

Functor Event

Methods

fmap :: (a -> b) -> Event a -> Event b

(<$) :: a -> Event b -> Event a

Eq (NickName a) => Eq (Event a)

Methods

(==) :: Event a -> Event a -> Bool

(/=) :: Event a -> Event a -> Bool

Show (NickName a) => Show (Event a)

Methods

showsPrec :: Int -> Event a -> ShowS

show :: Event a -> String

showList :: [Event a] -> ShowS

data Source a

The source of an IRC message.

Constructors

User (NickName a)

The message comes directly from a user.

Channel (ChannelName a) (NickName a)

The message comes from a user in a channel.

Server (ServerName a)

The message comes directly from the server.

Instances

Functor Source

Methods

fmap :: (a -> b) -> Source a -> Source b

(<$) :: a -> Source b -> Source a

Eq (NickName a) => Eq (Source a)

Methods

(==) :: Source a -> Source a -> Bool

(/=) :: Source a -> Source a -> Bool

Show (NickName a) => Show (Source a)

Methods

showsPrec :: Int -> Source a -> ShowS

show :: Source a -> String

showList :: [Source a] -> ShowS

data Message a

A decoded IRC message.

Constructors

Privmsg (Target a) (Either CTCPByteString a)

A message, either from a user or to a channel the client is in. CTCPs are distinguished by starting and ending with a \001 (SOH).

Notice (Target a) (Either CTCPByteString a)

Like a privmsg, but should not provoke an automatic response.

Nick (NickName a)

Someone has updated their nick.

Join (ChannelName a)

Someone has joined a channel.

Part (ChannelName a) (Reason a)

Someone has left a channel.

Quit (Reason a)

Someone has left the network.

Mode (Target a) IsModeSet [ModeFlag a] [ModeArg a]

Someone has set some channel modes or user modes.

Topic (ChannelName a) a

Someone has set the topic of a channel.

Invite (ChannelName a) (NickName a)

The client has been invited to a channel.

Kick (ChannelName a) (NickName a) (Reason a)

Someone has been kicked from a channel.

Ping (ServerName a) (Maybe (ServerName a))

The client has received a server ping, and should send a pong asap.

Pong (ServerName a)

A pong sent to the named server.

Numeric Int [NumericArg a]

One of the many server numeric responses.

RawMsg a

Never produced by decoding, but can be used to send arbitrary bytestrings to the IRC server. Naturally, this should only be used when you are confident that the produced bytestring will be a valid IRC message.

Instances

Functor Message

Methods

fmap :: (a -> b) -> Message a -> Message b

(<$) :: a -> Message b -> Message a

Eq (Target a) => Eq (Message a)

Methods

(==) :: Message a -> Message a -> Bool

(/=) :: Message a -> Message a -> Bool

Show (Target a) => Show (Message a)

Methods

showsPrec :: Int -> Message a -> ShowS

show :: Message a -> String

Decoding messages

fromByteString :: ByteString -> Either ByteString IrcEvent

attemptDecode :: ByteString -> Maybe (IrcSource, IrcMessage)

Attempt to decode a ByteString into a message, returning a Nothing if either the source or the message can't be determined.

Encoding messages

toByteString :: IrcMessage -> ByteString

Encode an IRC message into a single bytestring suitable for sending to the server.

mkMessage :: ByteString -> [ByteString] -> ByteString

rawMessage

Arguments

:: ByteString

The command

-> [ByteString]

The arguments

-> IrcMessage

Construct a raw message.
