1. newtype ParsecT e s (m :: Type -> Type) a

   megaparsec	Text.Megaparsec.Internal

   ParsecT e s m a is a parser with custom data component of error e, stream type s, underlying monad m and return type a.

2. ParsecT :: (forall b . () => State s e -> (a -> State s e -> Hints (Token s) -> m b) -> (ParseError s e -> State s e -> m b) -> (a -> State s e -> Hints (Token s) -> m b) -> (ParseError s e -> State s e -> m b) -> m b) -> ParsecT e s (m :: Type -> Type) a

   megaparsec	Text.Megaparsec.Internal

   No documentation available.

3. module Text.Megaparsec.Pos

   Textual source position. The position includes name of file, line number, and column number. You probably do not want to import this module directly because Text.Megaparsec re-exports it anyway.

4. data Pos

   megaparsec	Text.Megaparsec.Pos

   Pos is the type for positive integers. This is used to represent line number, column number, and similar things like indentation level. Semigroup instance can be used to safely and efficiently add Poses together.

5. data PosState s

   megaparsec	Text.Megaparsec.State

   A special kind of state that is used to calculate line/column positions on demand.

6. PosState :: s -> Int -> SourcePos -> Pos -> String -> PosState s

   megaparsec	Text.Megaparsec.State

   No documentation available.

7. module Safe.Partial

   ConstraintKind synonym for marking partial functions

8. type Partial = HasCallStack

   safe	Safe.Partial

   A constraint synonym which denotes that the function is partial, and will (on GHC 8.* and up) produce a stack trace on failure. You may mark your own non-total functions as Partial, if necessary, and this will ensure that they produce useful stack traces.

9. type Partial = HasCallStack

   extra	Control.Exception.Extra

   A constraint which documents that a function is partial, and on GHC 8.0 and above produces a stack trace on failure. For example:

   myHead :: Partial => [a] -> a
   myHead [] = error "bad"
   myHead (x:xs) = x
   

   When using Partial with GHC 7.8 or below you need to enable the language feature ConstraintKinds, e.g. {-# LANGUAGE ConstraintKinds #-} at the top of the file.

10. type Partial = HasCallStack

    extra	Extra

    A constraint which documents that a function is partial, and on GHC 8.0 and above produces a stack trace on failure. For example:

    myHead :: Partial => [a] -> a
    myHead [] = error "bad"
    myHead (x:xs) = x
    

    When using Partial with GHC 7.8 or below you need to enable the language feature ConstraintKinds, e.g. {-# LANGUAGE ConstraintKinds #-} at the top of the file.
