A new dumper is created by a call
$d = new Dumpvalue(option1 => value1, option2 => value2)
Recognized options:
arrayDepth, hashDepthcompactDump, veryCompactglobPrintdumpDBFilesdumpPackagesdumpReusedtick, quoteHighBit, printUndeftick 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.
usageOnlydumpvars calculates total size of strings in variables in the package.
unctrl and quote.
Later in the life of the object the methods may be queries with get()
method and set() method (which accept multiple arguments).
$dumper->dumpValue($value); $dumper->dumpValue([$value1, $value2]);
Prints a dump to the currently selected filehandle.
$dumper->dumpValues($value1, $value2);
Same as $dumper-dumpValue([$value1, $value2]); >.
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.
$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.
$d->set_quote('"');
Sets tick and unctrl options to suitable values for printout with the
given quote char. Possible values are auto, ' and ".
$d->set_unctrl('"');
Sets unctrl option with checking for an invalid argument.
Possible values are unctrl and quote.
$d->compactDump(1);
Sets compactDump option. If the value is 1, sets to a reasonable
big number.
$d->veryCompact(1);
Sets compactDump and veryCompact options simultaneously.
$d->set(option1 => value1, option2 => value2);
@values = $d->get('option1', 'option2');
