Manual Reference Pages - DEVEL::DUMPVAR (3)
Devel::Dumpvar - A pure-OO reimplementation of dumpvar.pl
# Dump something immediately to STDOUT
Devel::Dumpvar->dump( [ foo ], $bar );
# Create a dump handle to use repeatedly
my $Dump = Devel::Dumpvar->new;
# Dump via the handler
$Dump->dump( foo, [ bar ] );
Most perl dumping modules are focused on serializing data structures
into a format that can be rebuilt into the original data structure.
They do this with a variety of different focuses, such as human
readability, the ability to execute the dumped code directly, or
to minimize the size of the dumped data.
Excect for the one contained in the debugger, in the file dumpvar.pl.
This is a much more human-readable form, highly useful for debugging,
containing a lot of extra information without the burden of needing to
allow the dump to be re-assembled into the original data.
The main downside of the dumper in the perl-debugger is that the
dumpvar.pl script is not really a readily loadable and useable module.
It has dedicated hooks from and to the debugger, and spans across
multiple namespaces, including main::.
Devel::Dumpvar is a pure object-orientated reimplementation of the
same functionality. This makes it much more versatile version to use
for dumping information to debug log files or other uses where you
dont need to reassemble the data.
new( option => value, ... )
The new constructor creates a new dumping object. Any options can
be passed a list of key/value pairs.
Each option passed to the constructor is set via one of the option
to( CW$output_destination )
The to option specifies where the output is to be sent to. When
undefined, output will go to STDOUT. The output destination can be
either a handle object ( or anything else with a ->print method ),
or the string return, which will cause the dump method to collect
and return the dump results for each call, rather than printing it
immediately to the output.
If called without an argument, returns the current value.
If called with an argument, returns true or dies on error.
dump( data1, data2, ... )
If called as an object method, dumps a number of data values or structs
to the dumping object. If called as a class method, creates a new
default dump object and immediately dumps to it, destroying the dumper
- Implement options currently available in other dumpers as needed.
- Currently only supports SCALAR, REF, ARRAY, HASH and Regexp.
Add support for all possible reference types.
