Ahh, figured it out myself:
qualifiedIdentifier :: CharParser st [ String ]
qualifiedIdentifier = do
i <- identifier
r <- dotIdentifier
return (i : r)
where
dotIdentifier = do
char '.'
i <- identifier
r <- dotIdentifier
return (i : r)
<|> return []
Does that look sane to people who know Haskell and Parsec
better than me?
Hi Erik,
have a look at the module Text.ParserCombinators.Parsec.Combinator.
Those functions should help you to build up parsers from smaller
building blocks.
Using sepBy1, the above parser can be written as
dot = T.dot lexer
qualifiedIdentifier = sepBy1 identifier dot
