Description
The monadic parser type and combinators to construct packrat parsers for code generator.
- parse :: MemoTable tbl => (forall s. Parser tbl str s a) -> SrcPos -> str -> Either ParseError a
- parseString :: MemoTable tbl => (forall s. Parser tbl str s a) -> String -> str -> Either ParseError a
- parseFile :: MemoTable tbl => (forall s. Parser tbl String s a) -> FilePath -> IO (Either ParseError a)
- newtype Parser tbl str s a = Parser {}
- data Result str a
- = Parsed SrcPos str a
- | Failed ParseError
- data ParseError = ParseError SrcLoc String
- class MemoTable tbl where
- memo :: (tbl s -> HashTable s Int (Result str a)) -> Parser tbl str s a -> Parser tbl str s a
- getPos :: Parser tbl str s SrcPos
- setPos :: SrcPos -> Parser tbl str s ()
- anyChar :: ListLike str Char => Parser tbl str s Char
- satisfy :: ListLike str Char => (Char -> Bool) -> Parser tbl str s Char
- char :: ListLike str Char => Char -> Parser tbl str s Char
- string :: ListLike str Char => String -> Parser tbl str s String
- expect :: ListLike str Char => Parser tbl str s a -> Parser tbl str s ()
- unexpect :: ListLike str Char => Parser tbl str s a -> Parser tbl str s ()
- space :: ListLike str Char => Parser tbl str s ()
