NAME¶
Net::Jabber::Bot - Automated Bot creation with safeties
VERSION¶
Version 2.1.5
SYNOPSIS¶
Program design: This is a Moose based Class.
The idea behind the module is that someone creating a bot should not really have
to know a whole lot about how the Jabber protocol works in order to use it. It
also allows us to abstract away all the things that can get a bot maker into
trouble. Essentially the object helps protect the coders from their own
mistakes.
All someone should have to know and define in the program away from the object
is:
- 1. Config - Where to connect, how often to do things,
timers, etc
- 2. A subroutine to be called by the bot object when a new
message comes in.
- 3. A subroutine to be called by the bot object every so
often that lets the user do background activities (check logs, monitor web
pages, etc.),
The object at present has the following enforced safeties as long as you do not
override safety mode:
- 1. Limits messages per second, configurable at start up,
(Max is 5 per second) by requiring a sleep timer in the message sending
subroutine each time one is sent.
- 2. Endless loops of responding to self prevented by now
allowing the bot message processing subroutine to know about messages from
self
- 3. Forum join grace period to prevent bot from reacting to
historical messages
- 4. Configurable aliases the bot will respond to per
forum
- 5. Limits maximum message size, preventing messages that
are too large from being sent (largest configurable message size limit is
1000).
- 6. Automatic chunking of messages to split up large
messages in message sending subroutine
- 7. Limit on messages per hour. (max configurable limit of
125) Messages are visible via log4perl, but not ever be sent once the
message limit is reached for that hour.
FUNCTIONS¶
- new
- Minimal:
my $bot = Net::Jabber::Bot->new(
server => 'host.domain.com' # Name of server when sending messages
internally.

server => 'host.domain.com' # Name of server when sending messages
internally.

, max_messages_per_hour => 100
);
Setup the object and connect to the server. Hash values are passed to new as
a hash.
The following initialization variables can be passed. Only marked variables
are required (TODO)
- safety_mode
-
safety_mode = (1,0)
Determines if the bot safety features are turned on and enforced. This mode
is on by default. Many of the safety features are here to assure you do
not crash your favorite jabber server with floods, etc. DO NOT turn it off
unless you're sure you know what you're doing (not just Sledge Hammer
ceratin)
- server
- Jabber server name
- server_host
- Defaults to the same value set for 'server' above. This is
where the bot initially connects. For google for instance, you should set
this to 'gmail.com'
- conference_server
- conferencee server (usually conference.$server_name)
- port
- Defaults to 5222
- tls Boolean value. defaults to 0. for google, it is
know that this value must be 1 to work.
- connection_type defaults to 'tcpip' also takes
'http'
- username
- The user you authenticate with to access the server. Not
full name, just the stuff to the left of the @...
- password
- password to get into the server
- alias
- This will be your nickname in rooms, as well as the login
resource (which can't have duplicates). I couldn't come up with any reason
these should not be the same so hardcoded them to be the same.
- forums_and_responses
- A hash ref which lists the forum names to join as the keys
and the values are an array reference to a list of strings they are
supposed to be responsive to. The array is order sensitive and an empty
string means it is going to respond to all messages in this forum. Make
sure you list this last.
The found 'response string' is assumed to be at the beginning of the
message. The message_funtion function will be called with the modified
string.
alias = jbot:, attention:
example1:
message: 'jbot: help'
passed to callback: 'help'
- message_function
- The subroutine the bot will call when a new message is
recieved by the bot. Only called if the bot's logic decides it's something
you need to know about.
- background_function
- The subroutine the bot will call when every so often
(loop_sleep_time) to allow you to do background activities outside jabber
stuff (check logs, web pages, etc.)
- loop_sleep_time
- Frequency background function is called.
- process_timeout
- Time Process() will wait if no new activity is
received from the server
- ignore_server_messages
- Boolean value as to whether we should ignore messages sent
to us from the jabber server (addresses can be a little cryptic and hard
to process)
- ignore_self_messages
- Boolean value as to whether we should ignore messages sent
by us.
BE CAREFUL if you turn this on!!! Turning this on risks potentially endless
loops. If you're going to do this, please be sure safety is turned on at
least initially.
- out_messages_per_second
- Limits the number of messages per second. Number must be
<gt> 0
default: 5
safety: 5
- max_message_size
- Specify maximimum size a message can be before it's split
and sent in pieces.
default: 1,000,000
safetey: 1,000
- max_messages_per_hour
- Limits the number of messages per hour before we refuse to
send them
default: 125
safetey: 166
- JoinForum
- Joins a jabber forum and sleeps safety time. Also prevents
the object from responding to messages for a grace period in efforts to
get it to not respond to historical messages. This has failed sometimes.
NOTE: No error detection for join failure is present at the moment.
(TODO)
- Process
- Mostly calls it's client connection's "Process"
call. Also assures a timeout is enforced if not fed to the subroutine You
really should not have to call this very often. You should mostly be
calling Start() and just let the Bot kernel handle all this.
- Start
- Primary subroutine save new called by the program. Does an
endless loop of: 1. Process 2. If Process failed, Reconnect to server over
larger and larger timeout 3. run background process fed from new, telling
it who I am and how many loops we have been through. 4. Enforce a sleep to
prevent server floods.
- ReconnectToServer
- You should not ever need to use this. the Start()
kernel usually figures this out and calls it.
Internal process 1. Disconnects 3. Re-initializes
- Disconnect
- Disconnects from server if client object is defined.
Assures the client object is deleted.
- IsConnected
- Reports connect state (true/false) based on the status of
client_start_time.
- _process_jabber_message - DO NOT CALL
- Handles incoming messages.
- get_responses
-
$bot->get_ident($forum_name);
Returns the array of messages we are monitoring for in supplied forum or
replies with undef.
- _jabber_in_iq_message - DO NOT CALL
- Called when the client receives new messages during Process
of this type.
- _jabber_presence_message - DO NOT CALL
- Called when the client receives new presence messages
during Process. Mostly we are just pushing the data down into the client
DB for later processing.
- respond_to_self_messages
-
$bot->respond_to_self_messages($value = 1);
Tells the bot to start reacting to it\'s own messages if non-zero is passed.
Default is 1.
- get_messages_this_hour
-
$bot->get_messages_this_hour();
replys with number of messages sent so far this hour.
- get_safety_mode
- Validates that we are in safety mode. Returns a bool as
long as we are an object, otherwise returns undef
- SendGroupMessage
-
$bot->SendGroupMessage($name, $message);
Tells the bot to send a message to the recipient room name
- SendPersonalMessage
-
$bot->SendPersonalMessage($recipient, $message);
How to send an individual message to someone.
$recipient must read as user@server/Resource or it will not send.
- SendJabberMessage
-
$bot->SendJabberMessage($recipient, $message, $message_type, $subject);
The master subroutine to send a message. Called either by the user,
SendPersonalMessage, or SendGroupMessage. Sometimes there is call to call
it directly when you do not feel like figuring you messaged you. Assures
message size does not exceed a limit and chops it into pieces if need be.
NOTE: non-printable characters (unicode included) will be stripped before
sending to the server via:
s/[^[:print:]]+/./xmsg
- SetForumSubject
-
$bot->SetForumSubject($recipient, $subject);
Sets the subject of a forum
- ChangeStatus
-
$bot->ChangeStatus($presence_mode, $status_string);
Sets the Bot's presence status. $presence mode could be something like:
(Chat, Available, Away, Ext. Away, Do Not Disturb). $status_string is an
optional comment to go with your presence mode. It is not required.
- GetRoster
-
$bot->GetRoster();
Returns a list of the people logged into the server. I suspect we really
want to know who is in a paticular forum right? In which case we need
another sub for this.
- GetStatus
- Need documentation from Yago on this sub.
- AddUser
- Need documentation from Yago on this sub.
- RmUser
- Need documentation from Yago on this sub.
