Pod::Simple::Debug -- put Pod::Simple into trace/debug mode
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;
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.
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.
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 ();
