@package aeson-diff
@version 0.1.1.1


-- | This module implements data types and operations to represent the
--   differences between JSON documents (i.e. a patch), to compare JSON
--   documents and extract such a patch, and to apply such a patch to a
--   JSON document.
module Data.Aeson.Diff

-- | Describes the changes between two JSON documents.
data Patch
patchOperations :: Patch -> [Operation]

-- | A path through a JSON document is a possibly empty sequence of
--   <a>Key</a>s.
type Path = [Key]

-- | Traverse a single layer of a JSON document.
data Key
OKey :: Text -> Key
AKey :: Int -> Key

-- | Descripts an atomic change to a JSON document.
data Operation

-- | Insert a value at a location.
Ins :: Path -> Value -> Operation
changePath :: Operation -> Path
changeValue :: Operation -> Value

-- | Delete the value at a location.
Del :: Path -> Value -> Operation
changePath :: Operation -> Path
changeValue :: Operation -> Value

-- | Compare two JSON documents and generate a patch describing the
--   differences.
diff :: Value -> Value -> Patch

-- | Apply a patch to a JSON document.
patch :: Patch -> Value -> Value

-- | Apply an <a>Operation</a> to a <a>Value</a>.
applyOperation :: Operation -> Value -> Value

-- | Format a <a>Patch</a>.
