.SH "NAME"
Net::XMPP::Debug \- XMPP Debug Module
.SH "SYNOPSIS"
.IX Header "SYNOPSIS"
Net::XMPP::Debug is a module that provides a developer easy access
to logging debug information.
.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
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.
.SS "Basic Functions"
.IX Subsection "Basic Functions"
.Vb 1
\&    $Debug = Net::XMPP::Debug\->new();
\&
\&    $Debug\->Init(
\&           level  => 2,
\&           file   => "stdout",
\&           header =>"MyScript");
\&
\&    $Debug\->Log0("Connection established");

.IP "new" 4
.IX Item "new"
.Vb 1
\&    new(hash)
.Ve
.Sp
creates the Debug object.  The hash argument is passed
to the Init function.  See that function description
below for the valid settings.
.IP "Init" 4
.IX Item "Init"
.Vb 7
\&    Init(
\&         level      => integer,
\&         file       => string,
\&         header     => string,
\&         setdefault => 0|1,
\&         usedefault => 0|1,
\&         time       => 0|1)
.Ve
.Sp
initializes the debug object.
.Sp
The \fBlevel\fR determines the maximum level of debug
messages to log:
.Sp
.Vb 5
\&  0 \- Base level Output (default)
\&  1 \- High level API calls
\&  2 \- Low level API calls
\&  ...
\&  N \- Whatever you want....
.Ve
.Sp
The \fBfile\fR determines where the debug log
goes.  You can either specify a path to
a file, or \*(L"stdout\*(R" (the default).  \*(L"stdout\*(R"
tells Debug to send all of the debug info
sent to this object to go to stdout.
.Sp
\&\fBheader\fR 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 \*(L"Debug\*(R").
.Sp
\&\fBsetdefault\fR saves the current filehandle
and makes it available for other Debug
objects to use.  To use the default set
\&\fBusedefault\fR to 1.
.Sp
The \fBtime\fR parameter specifies whether or not to add a
timestamp to the beginning of each logged line.
.IP "LogN" 4
.IX Item "LogN"
.Vb 1
\&  LogN(array)
.Ve
.Sp
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...)
.SH "EXAMPLE"
.IX Header "EXAMPLE"
.Vb 2
\&  $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", \e%hash);
.Ve
.PP
You would get the following log:
.PP
.Vb 3
\&    Example: test
\&    Example: level 2 test
\&    Example: hashtest { a=>"atest" b=>"btest" }
.Ve
.PP
If you had set the level to 1 instead of 2 you would get:
.PP
.Vb 2
\&    Example: test
\&    Example: hashtest { a=>"atest" b=>"btest" }
