hash::flatten
Hash::Flatten(3pm) User Contributed Perl Documentation Hash::Flatten(3pm)NAME
Hash::Flatten - flatten/unflatten complex data hashes
SYNOPSIS
# Exported functions
use Hash::Flatten qw(:all);
$flat_hash = flatten($nested_hash);
$nested_hash = unflatten($flat_hash);
# OO interface
my $o = new Hash::Flatten({
HashDelimiter => '->',
ArrayDelimiter => '=>',
OnRefScalar => 'warn',
});
$flat_hash = $o->flatten($nested_hash);
$nested_hash = $o->unflatten($flat_hash);
DESCRIPTION
Converts back and forth between a nested hash structure and a flat hash of delimited key-value pairs. Useful for protocols that only
support key-value pairs (such as CGI and DBMs).
Functional interface
$flat_hash = flatten($nested_hash, \%options)
Reduces a nested data-structure to key-value form. The top-level container must be hashref. For example:
$nested = {
'x' => 1,
'y' => {
'a' => 2,
'b' => 3
},
'z' => [
'a', 'b', 'c'
]
}
$flat = flatten($nested);
use Data::Dumper;
print Dumper($flat);
$VAR1 = {
'y.a' => 2,
'x' => 1,
'y.b' => 3,
'z:0' => 'a',
'z:1' => 'b',
'z:2' => 'c'
};
The "\%options" hashref can be used to override the default behaviour (see "OPTIONS").
$nested_hash = unflatten($flat_hash, \%options)
The unflatten() routine takes the flattened hash and returns the original nested hash (see "CAVEATS" though).
OO interface
$o = new Hash::Flatten(\%options)
Options can be squirreled away in an object (see "OPTIONS")
$flat = $o->flatten($nested)
Flatten the structure using the options stored in the object.
$nested = $o->unflatten($flat)
Unflatten the structure using the options stored in the object.
OPTIONS
HashDelimiter and ArrayDelimiter
By default, hash dereferences are denoted by a dot, and array dereferences are denoted by a colon. However you may change these
characters to any string you want, because you don't want there to be any confusion as to which part of a string is the 'key' and which
is the 'delimiter'. You may use multicharacter strings if you prefer.
OnRefScalar and OnRefRef and OnRefGlob
Behaviour if a reference of this type is encountered during flattening. Possible values are 'die', 'warn' (default behaviour but
warns) or a coderef which is passed the reference and should return the flattened value.
By default references to references, and references to scalars, are followed silently.
EscapeSequence
This is the character or sequence of characters that will be used to escape the hash and array delimiters. The default escape sequence
is '\'. The escaping strategy is to place the escape sequence in front of delimiter sequences; the escape sequence itself is escaped
by replacing it with two instances.
DisableEscapes
Stop the escaping from happening. No escape sequences will be added to flattened output, nor interpreted on the way back.
WARNING: If your structure has keys that contain the delimiter characters, it will not be possible to unflatten the structure
correctly.
CAVEATS
Any blessings will be discarded during flattening, so that if you flatten an object you must re-bless() it on unflattening.
Note that there is no delimiter for scalar references, or references to references. If your structure to be flattened contains scalar, or
reference, references these will be followed by default, i.e. "'foo' => \\\$foo" will be collapsed to "'foo' => $foo". You can
override this behaviour using the OnRefScalar and OnRefRef constructor option.
Recursive structures are detected and cause a fatal error.
SEE ALSO
The perlmonks site has a helpful introduction to when and why you might want to flatten a hash:
http://www.perlmonks.org/index.pl?node_id=234186
CGI::Expand
Unflattens hashes using "." as a delimiter, similar to Template::Toolkit's behaviour.
Tie::MultiDim
This provides a tie interface to unflattening a data structure if you specify a "template" for the structure of the data.
MLDBM
This also provides a tie interface but reduces a nested structure to key-value form by serialising the values below the top level.
