require 'rubygems'
require 'chilkat'

imap = Chilkat::CkImap.new()

#  Anything unlocks the component and begins a fully-functional 30-day trial.
success = imap.UnlockComponent("Anything for 30-day trial")
if (success != true)
    print imap.lastErrorText() + "\n"
    exit
end

#  Connect to an IMAP server.
success = imap.Connect("mail.chilkatsoft.com")
if (success != true)
    print imap.lastErrorText() + "\n"
    exit
end

#  Login
success = imap.Login("myLogin","myPassword")
if (success != true)
    print imap.lastErrorText() + "\n"
    exit
end

#  Select an IMAP mailbox
success = imap.SelectMailbox("Inbox")
if (success != true)
    print imap.lastErrorText() + "\n"
    exit
end

#  Once the mailbox is selected, the NumMessages property
#  will contain the number of messages in the mailbox.
#  You may loop from 1 to NumMessages to
#  fetch each message by sequence number.

bUid = false

n = imap.get_NumMessages()
for i in 1 .. n

    #  Download the email by sequence number.
    mimeStr = imap.fetchSingleAsMime(i,bUid)

    #  ... your application may process each MIME string...
end

#  An alternative is to download each email in the form of an
#  email object, like this:

for i in 1 .. n

    #  Download the email by sequence number.
    # email is a CkEmail
    email = imap.FetchSingle(i,bUid)

    #  ... your application may process the email object...

end

#  Disconnect from the IMAP server.
imap.Disconnect()
