module Main where

import           Data.Aeson
import qualified Data.HashMap.Strict as H
import           Data.JsonPointer

main :: IO ()
main =
  case jsonPointer "/foo" of
    Left e     -> print e
    Right pntr ->
      case resolvePointer pntr (Object $ H.singleton "foo" $ String "bar") of
        Left e2 -> print e2
        Right v -> print v

Output:

String "bar"
