net/imap idle

[Payton Swick]

Perhaps there's another way to do this without polling, but I added the
IMAP IDLE (and associated DONE) command to Shugo Maeda's excellent
net/imap API.

For those unaware, RFC 2177 adds the IDLE command to the IMAP
specification which allows the server to notify clients when a mailbox
has changed state (particularly when new mail has arrived).

When issued, an IDLE command requires a DONE to complete it, which
should be issued at least every 29 minutes, to prevent a timeout.

Anyway, here's the (tiny) piece of code I wrote to implement this; I
hope it's useful. Feel free to tell me what I did wrong.

class Net::IMAP
def idle
cmd = "IDLE"
synchronize do
tag = generate_tag
put_string(tag + " " + cmd)
put_string(CRLF)
end
end
def done
cmd = "DONE"
synchronize do
put_string(cmd)
put_string(CRLF)
end
end
end
