pod::simple::debug
Pod::Simple::Debug(3) User Contributed Perl Documentation Pod::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...
$debug_level = 0;
DESCRIPTION
This is an internal module for controlling the debug level (a.k.a. trace level) of Pod::Simple. This is of interest only to Pod::Simple
developers.
CAVEATS
Note that you should load this module before loading Pod::Simple (or any Pod::Simple-based class). If you try loading Pod::Simple::Debug
after &Pod::Simple::DEBUG is already defined, Pod::Simple::Debug will throw a fatal error to the effect that "it's s too late to call
Pod::Simple::Debug".
Note that the "use Pod::Simple::Debug ($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 ();
