A library to parse data serialized by PHP into Clojure data structures.

The namespace provides a single function, unserialize, which takes a string of serialized data and returns EDN.

(ns my.namespace
  (:require [bernie.core :refer [unserialize]]))

(unserialize "i:123;") ; => 123
(unserialize "a:2:{i:0;s:3:"foo";i:1;d:456.78;}") ; => ["foo" 456.78]
(unserialize "a:1:{s:3:"foo";i:123}") ; => {:foo 123}

If the data supplied is not valid then an exception will most likely be thrown.

When serializing, PHP makes no distinction between numerically indexed and associative arrays (as it's internal implementation doesn't care). In EDN though we do care as these will end up as vectors or hashmaps respectively.

Bernie takes the approach of checking an array's keys, and if they are all numeric it'll create a vector, otherwise you'll get back a hashmap.

For custom serialization ('C') Bernie assumes the content is serialized data itself. This is because the usual way this is used is as follows:

class Test implements \Serializable
{
    public function serialize()
    {
        return serialize(array(
            // properties
        ));
    }
}

The reference type 'R' is currently not supported, and will return nil.

(unserialize "R:1;") ; => nil

Any invalid data will throw a com.pugh.bernie.UnserializeException.

Bernie is available via Clojars.
