3. boolean :: P TT TT

   yi-mode-javascript	Yi.Syntax.JavaScript

   Parses any boolean.

4. newtype CBool

   base	Foreign.C.Types

   Haskell type representing the C bool type. (The concrete types of Foreign.C.Types#platform are platform-specific.)

5. CBool :: Word8 -> CBool

   base	Foreign.C.Types

   No documentation available.

6. fromBool :: Num a => Bool -> a

   base	Foreign.Marshal.Utils

   Convert a Haskell Bool to its numeric representation

7. toBool :: (Eq a, Num a) => a -> Bool

   base	Foreign.Marshal.Utils

   Convert a Boolean in numeric representation to a Haskell value

8. safeReadBool :: String -> Maybe Bool

   tasty	Test.Tasty.Options

   Parse a Bool case-insensitively.

9. withBool :: String -> (Bool -> Parser a) -> Value -> Parser a

   aeson	Data.Aeson

   withBool expected f value applies f to the Bool when value is a Boolean and fails otherwise.

   Error message example

   withBool "MyType" f (String "oops")
   -- Error: "parsing MyType failed, expected Boolean, but encountered String"
   

10. withBool :: String -> (Bool -> Parser a) -> Value -> Parser a

    aeson	Data.Aeson.Types

    withBool expected f value applies f to the Bool when value is a Boolean and fails otherwise.

    Error message example

    withBool "MyType" f (String "oops")
    -- Error: "parsing MyType failed, expected Boolean, but encountered String"
