Dumpvalue - provides screen dump of Perl data.


SYNOPSIS

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


DESCRIPTION

       Creation

       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', `HighBit', `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.

       `UsageOnly'
           very 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


       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.

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

       Methods

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

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

       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 (pos­
           sibly negated).

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

       set_quote
             $d->set_quote('"');

           Sets `tick' and `unctrl' options to suitable values
           for printout with the given quote char.  Possible val­
           ues are `auto', `'' and `"'.

             $d->set_unctrl('"');

           Sets `unctrl' option with checking for an invalid
           argument.  Possible values are `unctrl' and `quote'.

       compactDump
             $d->compactDump(1);

           Sets `compactDump' option.  If the value is 1, sets to
           a reasonable big number.

       veryCompact
             $d->veryCompact(1);

           Sets `compactDump' and `veryCompact' options simulta­
           neously.

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

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