Serialising to and from JSON5

The JSON5 Data Interchange Format (JSON5) is a superset of JSON that aims to alleviate some of the limitations of JSON by expanding its syntax to include some productions from ECMAScript 5.1.

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

Example

ghci> import Text.JSON5
ghci> 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 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> import Text.JSON5.Pretty
ghci> ppJSValue $ makeObj [("key1", JSString $ toJSString "value1"), ("key2", JSArray [JSNull, JSBool True])]
{"key1": "value1", "key2": [null, true]}

ghci> import Text.JSON5.Generic
ghci> ppJSValue $ toJSON $ Just [2,1,4]
{"Just": [2, 1, 4]}
ghci> fromJSON (JSString $ toJSString "string") :: Result String 
Ok "string"
