Pod::Simple::Debug

NAME

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

SYNOPSIS

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

Or:

  1.  my $debuglevel;
  2.  use Pod::Simple::Debug (\$debuglevel, 0);
  3.  ...some stuff that uses Pod::Simple to do stuff, but which
  4.   you don't want debug output from...
  6.  $debug_level = 4;
  7.  ...some stuff that uses Pod::Simple to do stuff, but which
  8.   you DO want debug output from...
  10.  $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:

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

is basically equivalent to:

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

And this:

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

is basically equivalent to this:

  1.   my $debug_level;
  2.   BEGIN { $debug_level = 0 }
  3.   BEGIN { sub Pod::Simple::DEBUG () { $debug_level }
  4.   use Pod::Simple ();
