-- | API for parsing "aeson" JSON tree into Haskell types
--   
--   A flexible parser DSL of JSON AST produced by the "aeson" library with
--   automated and highly detailed error reporting. Provides a featureful
--   toolkit for parsing real-world documents with schemas of any
--   complexity or ambiguity, which the <a>FromJSON</a> instances are
--   simply not fit for.
@package aeson-value-parser
@version 0.19.7.2

module AesonValueParser

-- | JSON <a>Value</a> AST parser.
--   
--   Its <a>Alternative</a> instance implements the logic of choosing
--   between the possible types of JSON values.
data Value a
run :: Value a -> Value -> Either Error a
runWithTextError :: Value a -> Value -> Either Text a

-- | Convert into a function directly applicable as definition of
--   <a>parseJSON</a>.
--   
--   Here's an example of how it can be used:
--   
--   <pre>
--   data Artist = Artist
--     { artistName :: Text,
--       artistGenres :: [Text]
--     }
--   
--   instance <a>FromJSON</a> Artist where
--     <a>parseJSON</a> = <a>runAsValueParser</a> $
--       <a>object</a> $ do
--         name &lt;- <a>field</a> "name" $ <a>string</a> <a>text</a>
--         genres &lt;- <a>field</a> "genres" $ <a>array</a> $ <a>elementList</a> $ <a>string</a> <a>text</a>
--         return $ Artist name genres
--   </pre>
