1. readForwardedFor :: ByteString -> Maybe ByteString

   bugsnag-wai	Network.Bugsnag.Wai

   No documentation available.

2. readFile :: FilePath -> IO String

   cabal-install-solver	Distribution.Solver.Compat.Prelude

   The readFile function reads a file and returns the contents of the file as a string. The file is read lazily, on demand, as with getContents.

3. readIO :: Read a => String -> IO a

   cabal-install-solver	Distribution.Solver.Compat.Prelude

   The readIO function is similar to read except that it signals parse failure to the IO monad instead of terminating the program.

4. readList :: Read a => ReadS [a]

   cabal-install-solver	Distribution.Solver.Compat.Prelude

   The method readList is provided to allow the programmer to give a specialised way of parsing lists of values. For example, this is used by the predefined Read instance of the Char type, where values of type String are expected to use double quotes, rather than square brackets.

5. readLn :: Read a => IO a

   cabal-install-solver	Distribution.Solver.Compat.Prelude

   The readLn function combines getLine and readIO.

6. readMaybe :: Read a => String -> Maybe a

   cabal-install-solver	Distribution.Solver.Compat.Prelude

   Parse a string using the Read instance. Succeeds if there is exactly one valid result.

   >>> readMaybe "123" :: Maybe Int
   Just 123
   

   >>> readMaybe "hello" :: Maybe Int
   Nothing
   

7. readParen :: Bool -> ReadS a -> ReadS a

   cabal-install-solver	Distribution.Solver.Compat.Prelude

   readParen True p parses what p parses, but surrounded with parentheses. readParen False p parses what p parses, but optionally surrounded with parentheses.

8. reads :: Read a => ReadS a

   cabal-install-solver	Distribution.Solver.Compat.Prelude

   equivalent to readsPrec with a precedence of 0.

9. readsPrec :: Read a => Int -> ReadS a

   cabal-install-solver	Distribution.Solver.Compat.Prelude

   attempts to parse a value from the front of the string, returning a list of (parsed value, remaining string) pairs. If there is no successful parse, the returned list is empty. Derived instances of Read and Show satisfy the following:

   • (x,"") is an element of (readsPrec d (showsPrec d x "")).
   That is, readsPrec parses the string produced by showsPrec, and delivers the value that showsPrec started with.

10. readPkgConfigDb :: Verbosity -> ProgramDb -> IO PkgConfigDb

    cabal-install-solver	Distribution.Solver.Types.PkgConfigDb

    Query pkg-config for the list of installed packages, together with their versions. Return a PkgConfigDb encapsulating this information.
