NAME
Acme::Given::Hash - you like given but it's too much typing.
SYNOPSIS
use Acme::Given::Hash;
my $result = $given ~~ gvn { $value1 => $scalar
, $value2 => do { ... }
, $value3 => sub{ ... }
} || $default ;
# is going to result in the same thing as:
my $result;
given($given) {
when ($value1) { $result = $scalar }
when ($value2) { $result = do{ ... }}
when ($value3) { $result = sub{...}->() }
default { $result = $default }
};
# if you use an arrayref you can do more complex matching
$result = $given ~~ gvn [ 'scalar' => 'still works, just like the hash'
, qr{reg} => [qw{also works}]
, [1..5] => 'works too'
, {a=>b,c=>d} => 'same here'
, sub{$_>100} => 'for subs $_ is localized to the value of $given.'
, gvn { foo => 'bar' } => 'also works but "bar" will be seen as a true value rather then the thing to match'
];
EXPORTED FUNCTIONS
gvn
my $given_hash_obj = gvn {...};
my $given_array_obj = gvn [...];
This is really just a simple constructor that blesses the given structure in to an object where ~~ is overridden as to trip the value of the structure.
