NAME

     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
         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.

     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 (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.

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

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

     set_unctrl
           $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
         simultaneously.

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


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