|
| Generalized Utilities |
|
| These functions are generalized versions of
ones you might see in the Char parser. |
|
| type GeneralizedToken a = (SourcePos, a) |
|
| type GeneralizedTokenParser a st b = GenParser (GeneralizedToken a) st b |
|
| togtok :: a -> GenParser b st (GeneralizedToken a) |
| Generate (return) a GeneralizedToken. |
|
| tokeng :: Show a => (a -> Maybe b) -> GeneralizedTokenParser a st b |
| 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 a |
| 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 a |
| Matches one item in a list and returns it. |
|
| noneOfg :: (Eq a, Show a) => [a] -> GeneralizedTokenParser a st a |
| Matches one item not in a list and returns it. |
|
| specificg :: (Eq a, Show a) => a -> GeneralizedTokenParser a st a |
| Matches one specific token and returns it. |
|
| allg :: Show a => GeneralizedTokenParser a st [a] |
| Matches all items and returns them |
|
| Other Utilities |
|
| notMatching :: GenParser a b c -> String -> GenParser a b () |
| 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. |
