perldoc Data::Dumper will get you the full docs, but this should suffice
for simple uses:
given the hash
%hash = (
this => 'that',
hork => 'up',
funny => 'fvbklejrbnvkbe',
subtree => {
name => 'file',
handler => 'on_file_activate',
},
array => [ qw(this is an array of words) ],
);
You could say
print Dumper(\%hash);
and get
$VAR1 = {
'subtree' => {
'handler' => 'on_file_activate',
'name' => 'file'
},
'hork' => 'up',
'funny' => 'fvbklejrbnvkbe',
'this' => 'that',
'array' => [
'this',
'is',
'an',
'array',
'of',
'words'
]
};
you could also say
print Data::Dumper->Dump([\%hash], [qw(new_hash)]);
and get
$new_hash = {
'subtree' => {
'handler' => 'on_file_activate',
'name' => 'file'
},
'hork' => 'up',
'funny' => 'fvbklejrbnvkbe',
'this' => 'that',
'array' => [
'this',
'is',
'an',
'array',
'of',
'words'
]
};
and even go so far as saying
eval Data::Dumper->Dump([\%hash], [qw(new_hash)]);
print "$new_hash->{funny}\n";
and get
fvbklejrbnvkbe
