=head1 NAME

Dumpvalue - provides screen dump of Perl data.

=head1 SYNOPSIS

use Dumpvalue;
  my $dumper = Dumpvalue->new;
  $dumper->set(globPrint => 1);
  $dumper->dumpValue(\*::);
  $dumper->dumpvars('main');
  my $dump = $dumper->stringify($some_value);

=head1 DESCRIPTION

=head2 Creation

A new dumper is created by a call

$d = Dumpvalue->new(option1 => value1, option2 => value2)

Recognized options:

=over 4

=item C<arrayDepth>, C<hashDepth>

Print only first N elements of arrays and hashes.  If false, prints all the
elements.

=item C<compactDump>, C<veryCompact>

Change style of array and hash dump.  If true, short array
may be printed on one line.

=item C<globPrint>

Whether to print contents of globs.

=item C<dumpDBFiles>

Dump arrays holding contents of debugged files.

=item C<dumpPackages>

Dump symbol tables of packages.

=item C<dumpReused>

Dump contents of "reused" addresses.

=item C<tick>, C<quoteHighBit>, C<printUndef>

Change style of string dump.  Default value of C<tick> is C<auto>, one
can enable either double-quotish dump, or single-quotish by setting it
to C<"> or C<'>.  By default, characters with high bit set are printed
I<as is>.  If C<quoteHighBit> is set, they will be quoted.

=item C<usageOnly>

rudimentary per-package memory usage dump.  If set,
C<dumpvars> calculates total size of strings in variables in the package.

=item unctrl

Changes the style of printout of strings.  Possible values are
C<unctrl> and C<quote>.

=item subdump

Whether to try to find the subroutine name given the reference.

=item bareStringify

Whether to write the non-overloaded form of the stringify-overloaded objects.

=item quoteHighBit

Whether to print chars with high bit set in binary or "as is".

=item stopDbSignal

Whether to abort printing if debugger signal flag is raised.

=back

Later in the life of the object the methods may be queries with get()
method and set() method (which accept multiple arguments).

=head2 Methods

=over 4

=item dumpValue

$dumper->dumpValue($value);
  $dumper->dumpValue([$value1, $value2]);

Prints a dump to the currently selected filehandle.

=item dumpValues

$dumper->dumpValues($value1, $value2);

Same as C<< $dumper->dumpValue([$value1, $value2]); >>.

=item stringify

my $dump = $dumper->stringify($value [,$noticks] );

Returns the dump of a single scalar without printing. If the second
argument is true, the return value does not contain enclosing ticks.
Does not handle data structures.

=item dumpvars

$dumper->dumpvars('my_package');
  $dumper->dumpvars('my_package', 'foo', '~bar$', '!......');

The optional arguments are considered as literal strings unless they
start with C<~> or C<!>, in which case they are interpreted as regular
expressions (possibly negated).

The second example prints entries with names C<foo>, and also entries
with names which ends on C<bar>, or are shorter than 5 chars.

=item set_quote

$d->set_quote('"');

Sets C<tick> and C<unctrl> options to suitable values for printout with the
given quote char.  Possible values are C<auto>, C<'> and C<">.

=item set_unctrl

$d->set_unctrl('unctrl');

Sets C<unctrl> option with checking for an invalid argument.
Possible values are C<unctrl> and C<quote>.

=item compactDump

$d->compactDump(1);

Sets C<compactDump> option.  If the value is 1, sets to a reasonable
big number.

=item veryCompact

$d->veryCompact(1);

Sets C<compactDump> and C<veryCompact> options simultaneously.

=item set

$d->set(option1 => value1, option2 => value2);

=item get

@values = $d->get('option1', 'option2');

=back
