Dumpvalue - provides screen dump of Perl data.
use Dumpvalue;
my $dumper = new Dumpvalue;
$dumper->set(globPrint => 1);
$dumper->dumpValue(\*::);
$dumper->dumpvars('main');
my $dump = $dumper->stringify($some_value);
A new dumper is created by a call
$d = new Dumpvalue(option1 => value1, option2 => value2)
Recognized options:
arrayDepth, hashDepth
Print only first N elements of arrays and hashes. If false, prints all the elements.
compactDump, veryCompact
Change style of array and hash dump. If true, short array may be printed on one line.
globPrint
Whether to print contents of globs.
dumpDBFiles
Dump arrays holding contents of debugged files.
dumpPackages
Dump symbol tables of packages.
dumpReused
Dump contents of ``reused'' addresses.
tick, quoteHighBit, printUndef
Change style of string dump. Default value of tick is auto, one
can enable either double-quotish dump, or single-quotish by setting it
to " or '. By default, characters with high bit set are printed
as is. If quoteHighBit is set, they will be quoted.
usageOnly
rudimentally per-package memory usage dump. If set,
dumpvars calculates total size of strings in variables in the package.
Changes the style of printout of strings. Possible values are
unctrl and quote.
Whether to try to find the subroutine name given the reference.
Whether to write the non-overloaded form of the stringify-overloaded objects.
Whether to print chars with high bit set in binary or ``as is''.
Whether to abort printing if debugger signal flag is raised.
Later in the life of the object the methods may be queries with get()
method and set() method (which accept multiple arguments).
$dumper->dumpValue($value); $dumper->dumpValue([$value1, $value2]);
Prints a dump to the currently selected filehandle.
$dumper->dumpValues($value1, $value2);
Same as $dumper-dumpValue([$value1, $value2]); >.
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.
$dumper->dumpvars('my_package');
$dumper->dumpvars('my_package', 'foo', '~bar$', '!......');
The optional arguments are considered as literal strings unless they
start with ~ or !, in which case they are interpreted as regular
expressions (possibly negated).
The second example prints entries with names foo, and also entries
with names which ends on bar, or are shorter than 5 chars.
$d->set_quote('"');
Sets tick and unctrl options to suitable values for printout with the
given quote char. Possible values are auto, ' and ".
$d->set_unctrl('unctrl');
Sets unctrl option with checking for an invalid argument.
Possible values are unctrl and quote.
$d->compactDump(1);
Sets compactDump option. If the value is 1, sets to a reasonable
big number.
$d->veryCompact(1);
Sets compactDump and veryCompact options simultaneously.
$d->set(option1 => value1, option2 => value2);
@values = $d->get('option1', 'option2');
