9 use XXX;
10 XXX my $dog = Dog->new({has => ['fleas', 'style']});
11 my $dog = XXX Dog->new({has => ['fleas', 'style']});
12 my $dog = Dog->new(XXX {has => ['fleas', 'style']});
13 my $dog = Dog->new({XXX has => ['fleas', 'style']});
14 my $dog = Dog->new({has => XXX ['fleas', 'style']});
15 my $dog = Dog->new({has => [XXX 'fleas', 'style']});
16
18 XXX.pm exports a function called XXX that you can put just about
19 anywhere
20 in your Perl code to make it die with a YAML dump of the arguments
21 to
22 its right.
23
24 The charm of XXX-debugging is that it is easy to type, rarely requires
25 parens and stands out visually so that you remember to remove it.
26
27 XXX.pm also exports WWW, YYY and ZZZ which do similar debugging things.
28
30 WWW WWW will warn a dump of its arguments, and then return the original
31 arguments. This means you can stick it in the middle of
32 expressions.
33
34 NOTE: If you use WWW with Test::More, it will "diag()" rather than
35 "warn()".
36
37 mnemonic: W for warn
38
39 XXX XXX will die with a dump of its arguments.
40
41 mnemonic: XXX == Death, Nudity
42
43 YYY YYY will print a dump of its arguments, and then return the
44 original arguments. This means you can stick it in the middle of
45 expressions.
46
47 NOTE: If you use YYY with Test::More, it will "note()" rather than
48 "print()".
49
50 mnemonic: YYY == Why Why Why??? or YAML YAML YAML
51
52 ZZZ ZZZ will Carp::confess a dump of its arguments.
53
54 mnemonic: You should confess all your sins before you sleep.
55 zzzzzzzz
56
58 By default, XXX uses YAML.pm to dump your data. You can change this
59 like so:
60
61 use XXX -with => 'Data::Dumper';
62 use XXX -with => 'Data::Dump';
63 use XXX -with => 'Data::Dump::Color';
64 use XXX -with => 'YAML::XS';
65 use XXX -with => 'YAML::SomeOtherYamlModule';
66 use XXX -with => 'JSON::Color';
67 use XXX -with => 'JSON::SomeOtherJsonModule';
68
69 Only modules with names beginning with 'YAML' or 'JSON', and the
70 Data::Dumper, Data::Dump, and Data::Dump::Color modules are supported.
71
72 If you need to load XXX with "require", you can set the dumper module
73 with the $XXX::DumpModule global variable.
74
75 require XXX;
76 $XXX::DumpModule = 'YAML::Syck';
77
78 XXX::XXX($variable);
79
81 If you call a debugging function that calls XXX for you, XXX will print
82 the wrong file and line number. To force XXX to skip a package in the
83 call stack, just define the "XXX_skip" constant like this:
84
85 package MyDebugger;
86 use constant XXX_skip => 1;
87 sub debug {
88 require XXX;
89 XXX::XXX(@_);
90 }
91
92 Now calls to MyDebugger::debug will print the file name you called it
93 from, not from MyDebugger itself.
