Pod::Simple::Debug(3perl)        Perl Programmers Reference Guide       Pod::Simple::Debug(3perl)



NAME
       Pod::Simple::Debug -- put Pod::Simple into trace/debug mode

SYNOPSIS
        use Pod::Simple::Debug (5);  # or some integer

       Or:

        my $debuglevel;
        use Pod::Simple::Debug (\$debuglevel, 0);
        ...some stuff that uses Pod::Simple to do stuff, but which
         you don't want debug output from...

        $debug_level = 4;
        ...some stuff that uses Pod::Simple to do stuff, but which
         you DO want debug output from...

        $debug_level = 0;

DESCRIPTION
       This is an internal module for controlling the debug level (a.k.a. trace level) of
       Pod::Simple.  This is of interest only to Pod::Simple developers.

CAVEATS
       Note that you should load this module before loading Pod::Simple (or any Pod::Simple-based
       class).  If you try loading Pod::Simple::Debug after &Pod::Simple::DEBUG is already
       defined, Pod::Simple::Debug will throw a fatal error to the effect that "it's s too late
       to call Pod::Simple::Debug".

       Note that the "use Pod::Simple::Debug (\$x, somenum)" mode will make Pod::Simple (et al)
       run rather slower, since &Pod::Simple::DEBUG won't be a constant sub anymore, and so
       Pod::Simple (et al) won't compile with constant-folding.

GUTS
       Doing this:

         use Pod::Simple::Debug (5);  # or some integer

       is basically equivalent to:

         BEGIN { sub Pod::Simple::DEBUG () {5} }  # or some integer
         use Pod::Simple ();

       And this:

         use Pod::Simple::Debug (\$debug_level,0);  # or some integer

       is basically equivalent to this:

         my $debug_level;
         BEGIN { $debug_level = 0 }
         BEGIN { sub Pod::Simple::DEBUG () { $debug_level }
         use Pod::Simple ();
