Hi all,
I have the following script

tie::hash::regex
Tie::Hash::Regex(3pm) User Contributed Perl Documentation Tie::Hash::Regex(3pm)
NAME
Tie::Hash::Regex - Match hash keys using Regular Expressions
SYNOPSIS
use Tie::Hash::Regex;
my %h;
tie %h, 'Tie::Hash::Regex';
$h{key} = 'value';
$h{key2} = 'another value';
$h{stuff} = 'something else';
print $h{key}; # prints 'value'
print $h{2}; # prints 'another value'
print $h{'^s'}; # prints 'something else'
print tied(%h)->FETCH(k); # prints 'value' and 'another value'
delete $h{k}; # deletes $h{key} and $h{key2};
or (new! improved!)
my $h : Regex;
DESCRIPTION
Someone asked on Perlmonks if a hash could do fuzzy matches on keys - this is the result.
If there's no exact match on the key that you pass to the hash, then the key is treated as a regex and the first matching key is returned.
You can force it to leap straight into the regex checking by passing a qr'ed regex into the hash like this:
my $val = $h{qr/key/};
"exists" and "delete" also do regex matching. In the case of "delete" all vlaues matching your regex key will be deleted from the hash.
One slightly strange thing. Obviously if you give a hash a regex key, then it's possible that more than one key will match (consider
c<$h{qw/./}>). It might be nice to be able to do stuff like:
my @vals = $h{$pat};
to get all matching values back. Unfortuately, Perl knows that a given hash key can only ever return one value and so forces scalar context
on the "FETCH" call when using the tied interface. You can get round this using the slightly less readable:
my @vals = tied(%h)->FETCH($pat);
ATTRIBUTE INTERFACE
From version 0.06, you can use attributes to define your hash as being tied to Tie::Hash::Regex. You'll need to install the module
Attribute::Handlers.
METHODS
FETCH
Get a value from the hash. If there isn't an exact match try a regex match.
EXISTS
See if a key exists in the hash. If there isn't an exact match try a regex match.
DELETE
Delete a key from the hash. If there isn't an exact match try a regex match.
