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');
