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)
Later in the life of the object the methods may be queries with get() method and set() method (which accept multiple arguments).
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. unctrl Changes the style of printout of strings. Possible values are unctrl and quote. subdump Whether to try to find the subroutine name given the reference. bareStringify Whether to write the non-overloaded form of the stringify-overloaded objects. quoteHighBit Whether to print chars with high bit set in binary or as is. stopDbSignal Whether to abort printing if debugger signal flag is raised.
dumpValue $dumper->dumpValue($value); $dumper->dumpValue([$value1, $value2]);
Prints a dump to the currently selected filehandle.
dumpValues $dumper->dumpValues($value1, $value2);
Same as $dumper-dumpValue([$value1, $value2]); >.
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.
dumpvars $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.
Sets tick and unctrl options to suitable values for printout with the given quote char. Possible values are auto, and ".
Sets unctrl option with checking for an invalid argument. Possible values are unctrl and quote.
Sets compactDump option. If the value is 1, sets to a reasonable big number.
Sets compactDump and veryCompact options simultaneously.
set $d->set(option1 => value1, option2 => value2); get @values = $d->get(option1, option2);
