Constructor Details
#initialize(jid, password, status = nil, status_message = "Available", host = nil, port = 5222) ⇒ Simple
Create a new Jabber::Simple client. You will be automatically connected to the Jabber server and your status message will be set to the string passed in as the status_message argument.
jabber = Jabber::Simple.new(“[email protected]”, “password”, “Chat with me - Please!”)

Instance Method Details
#accept_subscriptions=(accept_status) ⇒ Object
Change whether or not subscriptions (friend requests) are automatically accepted.

# File 'lib/xmpp4r-simple.rb', line 312 def accept_subscriptions=(accept_status) @accept_subscriptions = accept_status end |
#accept_subscriptions? ⇒ Boolean
Returns true if auto-accept subscriptions (friend requests) is enabled (default), false otherwise.

#add(*jids) ⇒ Object
Ask the users specified by jids for authorization (i.e., ask them to add you to their contact list). If you are already in the user’s contact list, add() will not attempt to re-request authorization. In order to force re-authorization, first remove() the user, then re-add them.
Example usage:
jabber_simple.add("[email protected]")
Because the authorization process might take a few seconds, or might never happen depending on when (and if) the user accepts your request, results are placed in the Jabber::Simple#new_subscriptions queue.

#connected? ⇒ Boolean

#contacts(*contacts, &block) ⇒ Object
If contacts is a single contact, returns a Jabber::Contact object representing that user; if contacts is an array, returns an array of Jabber::Contact objects.
When called with a block, contacts will yield each Jabber::Contact object in turn. This is mainly used internally, but exposed as an utility function.

#deliver(jid, message, type = :chat) ⇒ Object
Send a message to jabber user jid.
Valid message types are:
* :normal (default): a normal message.
* :chat: a one-to-one chat message.
* :groupchat: a group-chat message.
* :headline: a "headline" message.
* :error: an error message.
If the recipient is not in your contacts list, the message will be queued for later delivery, and the Contact will be automatically asked for authorization (see Jabber::Simple#add).
message should be a string or a valid Jabber::Message object. In either case, the message recipient will be set to jid.

#deliver_deferred(jid, message, type) ⇒ Object
Queue messages for delivery once a user has accepted our authorization request. Works in conjunction with the deferred delivery thread.
You can use this method if you want to manually add friends and still have the message queued for later delivery.

#new_subscriptions(&block) ⇒ Object
Returns an array of subscription notifications received since the last time new_subscriptions was called. Passing a block will yield each update in turn, allowing you to break part-way through processing (especially useful when your subscription handling code is not thread-safe (e.g., ActiveRecord).
e.g.:
jabber.new_subscriptions do |friend, presence|
puts "Received presence update from #{friend.to_s}: #{presence}"
end

# File 'lib/xmpp4r-simple.rb', line 279 def new_subscriptions(&block) dequeue(:new_subscriptions, &block) end |
#new_subscriptions? ⇒ Boolean

#presence_updates(&block) ⇒ Object
Returns an array of presence updates received since the last time presence_updates was called. Passing a block will yield each update in turn, allowing you to break part-way through processing (especially useful when your presence handling code is not thread-safe (e.g., ActiveRecord).
e.g.:
jabber.presence_updates do |friend, new_presence|
puts "Received presence update from #{friend}: #{new_presence}"

Available values for presence are:

It’s not possible to set an offline status - to do that, disconnect! :-)
