Exact lookup

1. readConstr :: DataType -> String -> Maybe Constr

   base	Data.Data

   Lookup a constructor via a string

2. readBinaryWith :: ReadPrec a -> ReadPrec b -> String -> (a -> b -> t) -> ReadPrec t

   base	Data.Functor.Classes

   readBinaryWith rp1 rp2 n c' matches the name of a binary data constructor and then parses its arguments using rp1 and rp2 respectively.

3. readData :: ReadPrec a -> ReadPrec a

   base	Data.Functor.Classes

   readData p is a parser for datatypes where each alternative begins with a data constructor. It parses the constructor and passes it to p. Parsers for various constructors can be constructed with readUnaryWith and readBinaryWith, and combined with (<|>) from the Alternative class.

4. readPrec1 :: (Read1 f, Read a) => ReadPrec (f a)

   base	Data.Functor.Classes

   Lift the standard readPrec and readListPrec functions through the type constructor.

5. readPrec2 :: (Read2 f, Read a, Read b) => ReadPrec (f a b)

   base	Data.Functor.Classes

   Lift the standard readPrec function through the type constructor.

6. readUnaryWith :: ReadPrec a -> String -> (a -> t) -> ReadPrec t

   base	Data.Functor.Classes

   readUnaryWith rp n c' matches the name of a unary data constructor and then parses its argument using rp.

7. readsBinary1 :: (Read1 f, Read1 g, Read a) => String -> (f a -> g a -> t) -> String -> ReadS t

   base	Data.Functor.Classes

   Deprecated: Use readsBinaryWith to define liftReadsPrec

8. readsBinaryWith :: (Int -> ReadS a) -> (Int -> ReadS b) -> String -> (a -> b -> t) -> String -> ReadS t

   base	Data.Functor.Classes

   readsBinaryWith rp1 rp2 n c n' matches the name of a binary data constructor and then parses its arguments using rp1 and rp2 respectively.

9. readsData :: (String -> ReadS a) -> Int -> ReadS a

   base	Data.Functor.Classes

   readsData p d is a parser for datatypes where each alternative begins with a data constructor. It parses the constructor and passes it to p. Parsers for various constructors can be constructed with readsUnary, readsUnary1 and readsBinary1, and combined with mappend from the Monoid class.

10. readsPrec1 :: (Read1 f, Read a) => Int -> ReadS (f a)

    base	Data.Functor.Classes

    Lift the standard readsPrec and readList functions through the type constructor.
