NAME

6       Devel::Dumpvar - A pure-OO reimplementation of dumpvar.pl
7

SYNOPSIS

9         use Devel::Dumpvar;
10
11         # Dump something immediately to STDOUT
12         Devel::Dumpvar->dump( [ 'foo' ], $bar' );
13
14         # Create a dump handle to use repeatedly
15         my $Dump = Devel::Dumpvar->new;
16
17         # Dump via the handler
18         $Dump->dump( 'foo', [ 'bar' ] );

DESCRIPTION

21       Most perl dumping modules are focused on serializing data structures
22       into a format that can be rebuilt into the original data structure.
23       They do this with a variety of different focuses, such as human
24       readability, the ability to execute the dumped code directly, or to
25       minimize the size of the dumped data.
26
27       Excect for the one contained in the debugger, in the file dumpvar.pl.
28       This is a much more human-readable form, highly useful for debugging,
29       containing a lot of extra information without the burden of needing to
30       allow the dump to be re-assembled into the original data.
31
32       The main downside of the dumper in the perl-debugger is that the
33       dumpvar.pl script is not really a readily loadable and useable module.
34       It has dedicated hooks from and to the debugger, and spans across
35       multiple namespaces, including main::.
36
37       Devel::Dumpvar is a pure object-orientated reimplementation of the same
38       functionality. This makes it much more versatile version to use for
39       dumping information to debug log files or other uses where you don't
40       need to reassemble the data.
41

METHODS

43   new( option => value, ... )
44       The "new" constructor creates a new dumping object. Any options can be
45       passed a list of key/value pairs.
46
47       Each option passed to the constructor is set via one of the option
48       methods below.
49
50   to( $output_destination )
51       The "to" option specifies where the output is to be sent to. When
52       undefined, output will go to STDOUT. The output destination can be
53       either a handle object ( or anything else with a ->print method ), or
54       the string 'return', which will cause the "dump" method to collect and
55       return the dump results for each call, rather than printing it
56       immediately to the output.
57
58       If called without an argument, returns the current value.  If called
59       with an argument, returns true or dies on error.
60
61   dump( data1, data2, ... )
62       If called as an object method, dumps a number of data values or structs
63       to the dumping object. If called as a class method, creates a new
64       default dump object and immediately dumps to it, destroying the dumper
65       afterwards.
66

TO DO

68         - Implement options currently available in other dumpers as needed.
69
70         - Currently only supports SCALAR, REF, ARRAY, HASH and Regexp.
71           Add support for all possible reference types.
72
