json5hs: Serialising to and from JSON5

---

This library provides a parser and pretty printer for converting between Haskell values and JSON5.

Example

ghci> import qualified Text.JSON5 as J
ghci> J.encode [("key1",1),("key2",2)]
"[[\"key1\",1],[\"key2\",2]]"

ghci> import Text.JSON5.String (runGetJSON)
ghci> input <- getLine 
{'singleQuotes': 0xabcde, pos: +3, infnan: +Infinity, escape: "\t\u1234", trailing-comma: ['here',], }
ghci> runGetJSON J.readJSValue input
Right (JSObject (JSONObject {fromJSObject = [("singleQuotes",JSNumber (JSRational (703710 % 1))),("pos",JSNumber (JSRational (3 % 1))),("infnan",JSNumber (JSInfNaN Infinity)),("escape",JSString (JSONString {fromJSString = "\t\4660"})),("trailing-comma",JSArray [JSString (JSONString {fromJSString = "here"})])]}))

ghci> ppJSValue (JSObject (JSONObject [("key1",JSString (JSONString "string")),("key2",JSNumber (JSRational 42)),("key3",JSArray [JSBool True,JSNull])]))
{"key1": "string", "key2": 42, "key3": [true, null]}
