GoIRC Client Framework
|
|
======================
|
|
|
|
### Acquiring and Building
|
|
|
|
Pretty simple, really:
|
|
|
|
goinstall github.com/fluffle/goirc
|
|
|
|
You can build the test client also with:
|
|
|
|
make
|
|
./gobot
|
|
|
|
This will connect to freenode and join `#go-nuts` by default, so be careful ;-)
|
|
|
|
### Using the framework
|
|
|
|
Synopsis:
|
|
|
|
import "flag"
|
|
import irc "github.com/fluffle/goirc/client"
|
|
|
|
func main() {
|
|
flag.Parse() // parses the logging flags.
|
|
c := irc.New("nick", "ident", "real name", false, nil, nil)
|
|
// Optionally, enable SSL
|
|
c.SSL = true
|
|
|
|
// Add handlers to do things here!
|
|
// e.g. join a channel on connect.
|
|
c.AddHandler("connected",
|
|
func(conn *irc.Conn, line *irc.Line) { conn.Join("#channel") })
|
|
// And a signal on disconnect
|
|
quit := make(chan bool)
|
|
c.AddHandler("disconnected),
|
|
func(conn *irc.Conn, line *irc.Line) { quit <- true }
|
|
|
|
// Tell client to connect
|
|
if err := c.Connect("irc.freenode.net"); err != nil {
|
|
fmt.Printf("Connection error: %s\n", err.String())
|
|
}
|
|
|
|
// Wait for disconnect
|
|
<-quit
|
|
}
|
|
|
|
The test client provides a good (if basic) example of how to use the framework.
|
|
Reading `client/handlers.go` gives a more in-depth look at how handlers can be
|
|
written. Commands to be sent to the server (e.g. PRIVMSG) are methods of the
|
|
main `*Conn` struct, and can be found in `client/commands.go` (not all of the
|
|
possible IRC commands are implemented yet). Events are produced directly from
|
|
the messages from the IRC server, so you have to handle e.g. "332" for
|
|
`RPL_TOPIC` to get the topic for a channel.
|
|
|
|
The vast majority of handlers implemented within the framework deal with state
|
|
tracking of all nicks in any channels that the client is also present in. These
|
|
handers are in `client/state_handlers.go`. State tracking is optional, and can
|
|
be enabled by passing `true` as the fourth argument to `client.New()`. This API
|
|
sucks and may change in the future.
|
|
|
|
### Misc.
|
|
|
|
Sorry the documentation is crap. Use the source, Luke.

|
[Feedback](mailto:a.bramley@gmail.com) on design decisions is welcome. I am
|
|
indebted to Matt Gruen for his work on
|
|
[go-bot](http://code.google.com/p/go-bot/source/browse/irc.go) which inspired
|
|
the re-organisation and channel-based communication structure of `*Conn.send()`
|
|
and `*Conn.recv()`. I'm sure things could be more asynchronous, still.
