🏷️ NAME

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

🚀 Quick Reference

Use Case	Command	Description
🔧 Set constant debug level	use Pod::Simple::Debug (5);	Enable debug output at level 5 (integer)
🔄 Use variable debug level	use Pod::Simple::Debug (\$debuglevel, 0);	Control debug level dynamically via scalar reference
⚠️ Load before Pod::Simple	—	Must load this module before Pod::Simple to avoid fatal error

📝 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

• 🔸 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".
• 🔸 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 ();
