VERSION

10

SYNOPSIS

12       The autobox::dump pragma adds, via the autobox pragma, a method to
13       normal expression (such as scalars, arrays, hashes, math, literals,
14       etc.)  that produces a human/perl readable representation of the value
15       of that expression.
16
17           use autobox::dump;
18
19           my $foo = "foo";
20           print $foo->perl;   # "foo";
21
22           print +(5*6)->perl; # 30;
23
24           my @a = (1..3);
25
26           print @a->perl;
27           # [
28           #  1,
29           #  2,
30           #  3
31           # ];
32
33           print {a=>1, b=>2}->perl;
34           # {
35           #  "a" => 1,
36           #  "b" => 2
37           # };
38
39           sub func {
40               my ($x, $y) = @_;
41               return $x + $y;
42           }
43
44           my $func = \&func;
45           print $func->perl;
46           #sub {
47           #    BEGIN {
48           #        $^H{'autobox_scope'} = q(154456408);
49           #        $^H{'autobox'} = q(HASH(0x93a3e00));
50           #        $^H{'autobox_leave'} = q(Scope::Guard=ARRAY(0x9435078));
51           #    }
52           #    my($x, $y) = @_;
53           #    return $x + $y;
54           #}
55
56           You can set Data::Dumper options by passing either arrayrefs of option
57           and value pairs or just keys (in which case the option will be set to
58           1).  The default options are C<qw/Indent Terse Useqq Sortkeys Deparse/>.
59
60           print ["a", 0, 1]->perl([Indent => 3], [Varname => "a"], qw/Useqq/);
61           #$a1 = [
62           #        #0
63           #        "a",
64           #        #1
65           #        0,
66           #        #2
67           #        1
68           #      ];
69
70           You can also call the class method ->options to set a different default.
71
72           #set Indent to 0, but leave the rest of the options
73           autobox::dump->options([Indent => 0], qw/Terse Useqq Sortkeys Deparse/);
74
75           print ["a", 0, 1]->perl; #["a",0,1]

BUGS

81       Has all the issues autobox has.
82
83       Has all the issues Data::Dumper has.
84
85       This pragma errs on the side of human readable to the detriment of Perl
86       readable.  In particular it uses the terse and deparse options of
87       Data::Dumper by default.  These options may create code that cannot be
88       eval'ed.  For best eval results, set options to "qw/Purity/".  Note,
89       this turns off coderef dumping.
