1. type ReadS a = String -> [(a, String)]

   mixed-types-num	Numeric.MixedTypes.PreludeHiding

   A parser for a type a, represented as a function that takes a String and returns a list of possible parses as (a,String) pairs. Note that this kind of backtracking parser is very inefficient; reading a large structure may be quite slow (cf ReadP).

2. ReadOnly :: Mode

   mmap	System.IO.MMap

   file is mapped read-only, file must exist

3. ReadWrite :: Mode

   mmap	System.IO.MMap

   file is mapped read-write, file must exist

4. ReadWriteEx :: Mode

   mmap	System.IO.MMap

   file is mapped read-write, if file does not exist it will be created with default permissions, region parameter specifies size, if file size is lower it will be extended with zeros

5. module Control.Monad.Reader

   • Computation type: Computations which read values from a shared environment.
   • Binding strategy: Monad values are functions from the environment to a value. The bound function is applied to the bound value, and both have access to the shared environment.
   • Useful for: Maintaining variable bindings, or other shared environment.
   • Zero and plus: None.
   • Example type: Reader [(String,Value)] a
   The Reader monad (also called the Environment monad). Represents a computation, which can read values from a shared environment, pass values from function to function, and execute sub-computations in a modified environment. Using Reader monad for such computations is often clearer and easier than using the State monad. Inspired by the paper /Functional Programming with Overloading and Higher-Order Polymorphism/, Mark P Jones (http://web.cecs.pdx.edu/~mpj/) Advanced School of Functional Programming, 1995.

6. type Reader r = ReaderT r Identity

   monads-tf	Control.Monad.Reader

   The parameterizable reader monad. Computations are functions of a shared environment. The return function ignores the environment, while m >>= k passes the inherited environment to both subcomputations:

7. newtype ReaderT r (m :: Type -> Type) a

   monads-tf	Control.Monad.Reader

   The reader monad transformer, which adds a read-only environment to the given monad. The return function ignores the environment, while m >>= k passes the inherited environment to both subcomputations:

8. ReaderT :: (r -> m a) -> ReaderT r (m :: Type -> Type) a

   monads-tf	Control.Monad.Reader

   No documentation available.

9. ReadError :: Text -> String -> AddCellErrors

   xlsx	Codec.Xlsx.Parser.Stream

   Could not read current cell value

10. data ReadingOrder

    xlsx	Codec.Xlsx.Types.StyleSheet

    Reading order See 18.8.1 "alignment (Alignment)" (p. 1754, esp. p. 1755)
