Perl version 5.10.0 documentation - Pod::Simple::Debug

NAME

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

SYNOPSIS

use Pod::Simple::Debug (5);

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;

# or some integer

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);

is basically equivalent to:

BEGIN { sub Pod::Simple::DEBUG () {5} }

use Pod::Simple ();

And this:

use Pod::Simple::Debug (\$debug_level,0);

is basically equivalent to this:

my $debug_level;

BEGIN { $debug_level = 0 }

BEGIN { sub Pod::Simple::DEBUG () { $debug_level }

use Pod::Simple ();

# or some integer
