RedHat 9 (Linux i386) - man page for dumpvalue (redhat section 3pm)

Dumpvalue(3pm)			 Perl Programmers Reference Guide		   Dumpvalue(3pm)

NAME
       Dumpvalue - provides screen dump of Perl data.

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

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", "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, char-
	   acters 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.

       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]);

	   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.

       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 "unc-
	   trl" 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');
