6 Pod::Simple::Debug -- put Pod::Simple into trace/debug mode
7
9 use Pod::Simple::Debug (5); # or some integer
10
11 Or:
12
13 my $debuglevel;
14 use Pod::Simple::Debug (\$debuglevel, 0);
15 ...some stuff that uses Pod::Simple to do stuff, but which
16 you don't want debug output from...
17
18 $debug_level = 4;
19 ...some stuff that uses Pod::Simple to do stuff, but which
20 you DO want debug output from...
21
22 $debug_level = 0;
23
25 This is an internal module for controlling the debug level (a.k.a.
26 trace level) of Pod::Simple. This is of interest only to Pod::Simple
27 developers.
28
30 Note that you should load this module before loading Pod::Simple (or
31 any Pod::Simple-based class). If you try loading Pod::Simple::Debug
32 after &Pod::Simple::DEBUG is already defined, Pod::Simple::Debug will
33 throw a fatal error to the effect that "It's too late to call
34 Pod::Simple::Debug".
35
36 Note that the "use Pod::Simple::Debug (\$x, somenum)" mode will make
37 Pod::Simple (et al) run rather slower, since &Pod::Simple::DEBUG won't
38 be a constant sub anymore, and so Pod::Simple (et al) won't compile
39 with constant-folding.

42 Doing this:
43
44 use Pod::Simple::Debug (5); # or some integer
45
46 is basically equivalent to:
47
48 BEGIN { sub Pod::Simple::DEBUG () {5} } # or some integer
49 use Pod::Simple ();
50
51 And this:
52
53 use Pod::Simple::Debug (\$debug_level,0); # or some integer
54
55 is basically equivalent to this:
56
57 my $debug_level;
58 BEGIN { $debug_level = 0 }
59 BEGIN { sub Pod::Simple::DEBUG () { $debug_level }
60 use Pod::Simple ();
