Initializing an Ivy agent with the Ivy-Perl library is done by calling function Ivy::start. In theory, initialization is then over. However in
+practice, as for any asynchronous communication or interaction library, nothing
+happens until your application has reached the main loop.
+
The Ivy Perl library provides two kind of main loop: a "local" loop + for perl code, and a "Tk" loop for perl-tk code. +
Here is more details on Ivy::start function:
+
+
+
+ Ivy::start(-loopMode => 'TK',
+ -ivyBus => '2011',
+ -appName => "TOTO",
+ -neededApp => "TITI",
+ -statusFunc => \&statusScan);
+
+
+ivyBus. The string provided
+should follow the convention described in section XX. Example: "127:2010"..
++ +
+
+MainLoop;
+
++
+
+Ivy::stop ();
+
++
+
Emitting a message on an Ivy bus is much like printing a message on the standard
+output. However, do not forget that your message will not be emitted if Ivy has
+not been properly initialized and if you do not have a main loop of some sort
+running. To emit a message, use IvySendMsg, which works like printf:
+
+
+
+Ivy::sendMsg ("...");
+
++
+
Subscribing to messages consists in binding a callback function to a message
+pattern. Patterns are described by regular expressions with captures. When a
+message matching the regular expression is detected on the bus, the callback
+function is called. The captures (ie the bits of the message that match the
+parts of regular expression delimited by brackets) are passed to the callback
+function much like options are passed to main. Use function Ivy::bindRegexp
+to bind a callback to a pattern.
+
+
+Ivy::bindRegexp ("^HELLO WORLD", [\&Start]);
+
+Start to the regular expression specified by
+regex_format.
++
+
+Ivy::bindRegexp ("^HELLO WORLD", NULL);
+
