Change `Parser` type name to `Parsero`

The Parser type takes two arguments: the stream type and the result type. That leads to all parser functions being written like this: p :: Stream s => Parser s a. Changing the constructor to Parsero/MkParsero would let us define a type synonym specifying which stream type we want to use, avoiding repetition: type Parser = Parsero Text

New parser combinators

  • choice :: [Parser a] -> Parser a
  • option :: a -> Parser a -> Parser a
  • surroundedBy :: Parser a -> Parser s -> Parser a
  • try :: Parser a -> Parser a
  • sepBy :: [Parser a] -> Parser a
  • sepBy1 :: [Parser a] -> Parser a
  • eol :: Parser Char
