Net::XMPP::Debug - XMPP Debug Module

Net::XMPP::Debug is a module that provides a developer easy access to logging debug information.

Debug is a helper module for the Net::XMPP modules. It provides the Net::XMPP modules with an object to control where, how, and what is logged.

    $Debug = Net::XMPP::Debug->new();
    $Debug->Init(
           level  => 2,
           file   => "stdout",
           header =>"MyScript");
    $Debug->Log0("Connection established");

new
    new(hash)
    
creates the Debug object. The hash argument is passed to the Init function. See that function description below for the valid settings.
Init
    Init(
         level      => integer,
         file       => string,
         header     => string,
         setdefault => 0|1,
         usedefault => 0|1,
         time       => 0|1)
    
initializes the debug object.
The level determines the maximum level of debug messages to log:
  0 - Base level Output (default)
  1 - High level API calls
  2 - Low level API calls
  ...
  N - Whatever you want....
    
The file determines where the debug log goes. You can either specify a path to a file, or "stdout" (the default). "stdout" tells Debug to send all of the debug info sent to this object to go to stdout.
header is a string that will preappended to the beginning of all log entries. This makes it easier to see what generated the log entry (default is "Debug").
setdefault saves the current filehandle and makes it available for other Debug objects to use. To use the default set usedefault to 1.
The time parameter specifies whether or not to add a timestamp to the beginning of each logged line.
LogN
  LogN(array)
    
Logs the elements of the array at the corresponding debug level N. If you pass in a reference to an array or hash then they are printed in a readable way. (ie... Log0, Log2, Log100, etc...)

  $Debug = Net::XMPP:Debug->new(level=>2,
                               header=>"Example");
  $Debug->Log0("test");
  $Debug->Log2("level 2 test");
  $hash{a} = "atest";
  $hash{b} = "btest";
  $Debug->Log1("hashtest", \%hash);
You would get the following log:
    Example: test
    Example: level 2 test
    Example: hashtest { a=>"atest" b=>"btest" }
If you had set the level to 1 instead of 2 you would get:
    Example: test
    Example: hashtest { a=>"atest" b=>"btest" }
