Generalized Utilities
These functions are generalized versions of ones you might see in the Char parser.
type GeneralizedToken a = (SourcePos, a)Source
type GeneralizedTokenParser a st b = GenParser (GeneralizedToken a) st bSource
togtok :: a -> GenParser b st (GeneralizedToken a)Source
Generate (return) a GeneralizedToken.
tokeng :: Show a => (a -> Maybe b) -> GeneralizedTokenParser a st bSource
Retrieve the next token from a GeneralizedToken stream. The given function should return the value to use, or Nothing to cause an error.
satisfyg :: Show a => (a -> Bool) -> GeneralizedTokenParser a st aSource
A shortcut to tokeng; the test here is just a function that returns a Bool. If the result is true; return that value -- otherwise, an error.
oneOfg :: (Eq a, Show a) => [a] -> GeneralizedTokenParser a st aSource
Matches one item in a list and returns it.
noneOfg :: (Eq a, Show a) => [a] -> GeneralizedTokenParser a st aSource
Matches one item not in a list and returns it.
specificg :: (Eq a, Show a) => a -> GeneralizedTokenParser a st aSource
Matches one specific token and returns it.
allg :: Show a => GeneralizedTokenParser a st [a]Source
Matches all items and returns them
Other Utilities
notMatching :: GenParser a b c -> String -> GenParser a b ()Source
Running notMatching p msg will try to apply parser p. If it fails, returns (). If it succeds, cause a failure and raise the given error message. It will not consume input in either case.
