A new dumper is created by a call

$d = Dumpvalue->new(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

#tick,quoteHighBit,printUndef

Change style of string dump. Default value oftick isauto, one can enable either double-quotish dump, or single-quotish by setting it to" or'. By default, characters with high bit set are printedas is. IfquoteHighBit is set, they will be quoted.

#usageOnly

rudimentary 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 areunctrl andquote.

#subdump

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 namesfoo, and also entries with names which ends onbar, or are shorter than 5 chars.

#set_quote

$d->set_quote('"');

Setstick andunctrl options to suitable values for printout with the given quote char. Possible values areauto,' and".

#set_unctrl

$d->set_unctrl('unctrl');

Setsunctrl option with checking for an invalid argument. Possible values areunctrl andquote.

#compactDump

$d->compactDump(1);

SetscompactDump option. If the value is 1, sets to a reasonable big number.

#veryCompact

$d->veryCompact(1);

SetscompactDump andveryCompact options simultaneously.

#set

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

#get

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