Virtual Hosts in HHVM

This is a simple way of creating Virtual Hosts for HHVM. When you’re doing this on your local machine. Don’t forget to edit your hosts file and add a loop back to the domain (ex. 127.0.0.1 collideborate.local)

HackLang: Vector、Map、Set で filter、map を使う

Vector、Map にはキーを引数にとることのできる filterWithKey、mapWithKey も用意されている。reduce は用意されていない。

$v = Vector {1, 2, 3, 4, 5, 6, 7, 8, 9, 10}; $ret = $v->filter($value ==> $value % 2 === 0) ->map($value ==> $value * $value); $ret2 = $v->filterWithKey(($key, $value) ==> $key % 2 === 0) ->mapWithKey(($key, $value) ==> $value * $value); var_dump( [4, 16, 36, 64, 100] === $ret->toArray(), [1, 9, 25, 49, 81] === $ret2->toArray() );

$map = Map {'a' => 1, 'b' => 2, 'c' => 3, 'd' => 4, 'e' => 5 }; $ret3 = $map->filter($value ==> $value % 2 === 0) ->map($value ==> $value * $value); $ret4 = $map->filterWithKey(($key, $value) ==> $key === 'c' || $key === 'e') ->mapWithKey(($key, $value) ==> $value * $value); var_dump( ['b' => 4, 'd' => 16] === $ret3->ToArray(), ['c' => 9, 'e' => 25] === $ret4->ToArray() );

Set の場合、filterWithKey、mapWithKey は用意されていない。

$set = Set {1, 2, 3, 4, 5, 6, 7, 8, 9, 10}; $ret5 = $set->filter($value ==> $value % 2 === 0) ->map($value ==> $value * $value); var_dump([4, 16, 36, 64, 100] === $ret5->toValuesArray());
