Package for implementing XMPP clients and components.
Package for implementing XMPP clients and components.
The package is built around the concept of an XML stream - a pair of XML
documents written to and read from a TCP connection. Top-level elements in
the document form the messages processed by either end of the connection.

An XML stream is then configured for an XMPP conversation, as either a
client (chat, etc) or component (a sort of server plugin).

Create a client:
Create a client:
jid, err := xmpp.ParseJID("alice@wonderland.lit/some-resource")
addr, err := xmpp.HomeServerAddrs(jid)
stream, err := xmpp.NewStream(addr[0], nil)
X, err := xmpp.NewClientXMPP(stream, jid, "password", nil)
jid, err := xmpp.ParseJID("alice@wonderland.lit/some-resource")

Create a component:
Create a component:
jid, err := xmpp.ParseJID("rabbithole.wonderland.lit")
stream, err := xmpp.NewStream("localhost:5347", nil)
X, err := xmpp.NewComponentXMPP(stream, jid, "secret")

stream, err := xmpp.NewStream("localhost:5347", nil)
X, err := xmpp.NewComponentXMPP(stream, jid, "secret")
Outgoing XMPP stanzas are sent to the XMPP instance's Out channel, e.g. a
client typically announces its presence on the XMPP network as soon as it's
connected:
Outgoing XMPP stanzas are sent to the XMPP instance's Out channel, e.g. a
client typically announces its presence on the XMPP network as soon as it's
connected:
X.Out <- xmpp.Presence{}
X.Out <- xmpp.Presence{}
Incoming messages are handled by consuming the XMPP instance's In channel.
The channel is sent all XMPP stanzas as well as terminating error (io.EOF
for clean shutdown or any other error for something unexpected). The
channel is also closed after an error.

XMPP defines four types of stanza: <error/>, <iq/>, <message/> and
<presence/> represented by Error, Iq, Message (shown below) and Presence
structs respectively.

Note: A "bound" JID is negotatiated during XMPP setup and may be different
to the JID passed to the New(Client|Component)XMPP() call. Always
use the XMPP instance's JID attribute in any stanzas.
