Pod::Simple::Debug(3) User Contributed Perl DocumentationPod::Simple::Debug(3)
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 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 ();
