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 }
};
EXPORTED FUNCTIONS
gvn
my $given_hash_obj = gvn {...};
This is really just a simple constructor that blesses the given hashref to an object where ~~ is overridden as to trip the value of the hash rather then check to see if the key exists.
TODO
non-scalar matches
Currently the expectation is that you are matching a scalar as one would expect for a given/switch statement, it's not a hard problem to deal with arrays. Though currently there is no need to do this, possibly in the future?
