###cl-json-helper: A Common Lisp library to assist cl-json.

cl-json encodes and decodes JSON data. cl-json-helper adds two functions to help encoding JSON data and one function to help in processing decoded JSON data.

The nickname xjson can be used for the cl-json-helper package.

[Function]
json-empty ()

	The return value is decoded by cl-json as {}.
	
	Example:
		(cl-json:encode-json-to-string `(("Empty" . ,(xjson:json-empty))))
	=> "{\"Empty\":{}}"

[Function]
json-bool (val)

	Encodes val as "true" or "false"

	Examples:
		(cl-json:encode-json-to-string `(("TRUE" . ,(xjson:json-bool t))))
	=> "{\"TRUE\":true}"
		(cl-json:encode-json-to-string `(("FALSE" . ,(xjson:json-bool nil))))
	=> "{\"FALSE\":false}"

[Function]
json-key-value (key list &key (test #'eql))

	Return the value associated with _key_ in a decoded JSON list, if present, and whether
	or not _key_ was found.
	
	(cl-json:encode-json-to-string '(("HELLO" . "WORLD")
	                                 ("ITS" . "ME")
	                                 ("CEST" . "MOI")))
	=> "{\"HELLO\":\"WORLD\",\"ITS\":\"ME\",\"CEST\":\"MOI\"}"
	
	(cl-json:decode-json-from-string "{\"HELLO\":\"WORLD\",\"ITS\":\"ME\",\"CEST\":\"MOI\"}")
	=> ((:+HELLO+ . "WORLD") (:+ITS+ . "ME") (:+CEST+ . "MOI"))
	
	(xjson:json-key-value :+CEST+ '((:+HELLO+ . "WORLD") (:+ITS+ . "ME") (:+CEST+ . "MOI")))
	=> "MOI"
	   T
	
	(xjson:json-key-value :+FALSE+ (cl-json:decode-json-from-string "{\"FALSE\":false}"))
	=> NIL
	   T
	
	(xjson:json-key-value :+BAR+ (cl-json:decode-json-from-string "{\"FALSE\":false}"))
	=> NIL
	   NIL

json-key-value is just a glorified call to Lisp's assoc
