autobox::dump
autobox::dump(3pm) User Contributed Perl Documentation autobox::dump(3pm)
NAME
autobox::dump - human/perl readable strings from the results of an EXPR
VERSION
Version 20090426.1746
SYNOPSIS
The autobox::dump pragma adds, via the autobox pragma, a method to normal expression (such as scalars, arrays, hashes, math, literals,
etc.) that produces a human/perl readable representation of the value of that expression.
use autobox::dump;
my $foo = "foo";
print $foo->perl; # "foo";
print +(5*6)->perl; # 30;
my @a = (1..3);
print @a->perl;
# [
# 1,
# 2,
# 3
# ];
print {a=>1, b=>2}->perl;
# {
# "a" => 1,
# "b" => 2
# };
sub func {
my ($x, $y) = @_;
return $x + $y;
}
my $func = &func;
print $func->perl;
#sub {
# BEGIN {
# $^H{'autobox_scope'} = q(154456408);
# $^H{'autobox'} = q(HASH(0x93a3e00));
# $^H{'autobox_leave'} = q(Scope::Guard=ARRAY(0x9435078));
# }
# my($x, $y) = @_;
# return $x + $y;
#}
You can set Data::Dumper options by passing either arrayrefs of option
and value pairs or just keys (in which case the option will be set to
1). The default options are C<qw/Indent Terse Useqq Sortkeys Deparse/>.
print ["a", 0, 1]->perl([Indent => 3], [Varname => "a"], qw/Useqq/);
#$a1 = [
# #0
# "a",
# #1
# 0,
# #2
# 1
# ];
You can also call the class method ->options to set a different default.
#set Indent to 0, but leave the rest of the options
autobox::dump->options([Indent => 0], qw/Terse Useqq Sortkeys Deparse/);
print ["a", 0, 1]->perl; #["a",0,1]

BUGS
Has all the issues autobox has.
Has all the issues Data::Dumper has.
This pragma errs on the side of human readable to the detriment of Perl readable. In particular it uses the terse and deparse options of
Data::Dumper by default. These options may create code that cannot be eval'ed. For best eval results, set options to "qw/Purity/". Note,
this turns off coderef dumping.
Please report any bugs or feature requests to http://github.com/cowens/autobox-dump/issues
SUPPORT
You can find documentation for this module with the perldoc command.
