This example uses the third-party library "Jiffy".

===Encoding===

<lang lisp>

(: jiffy encode (list 1 2 3 '"apple" 'true 3.14))

</lang>

The result from that can be made a little more legible with the following:

<lang lisp>

(: erlang binary_to_list

(: jiffy encode (list 1 2 3 '"apple" 'true 3.14)))

</lang>

===Decoding===

We can run the encoding example in reverse, and get back what we put in above with the following:

<lang lisp>

(: jiffy decode '"[1,2,3,[97,112,112,108,101],true,3.14]")

</lang>

Here's a key-value example:

<lang lisp>

(: jiffy decode '"{\"foo\": [1, 2, 3]}")

</lang>

===Decoding to Patterns===

We can also extract the key and value using Erlang patterns:

<lang lisp>

(let (((tuple (list (tuple key value)))

(: jiffy decode '"{\"foo\": [1, 2, 3]}")))

(: io format '"~p: ~p~n" (list key value)))

</lang>
