Hi Haskellers!
I'm currently trying to write an assembler for Knuths MMIXAL language.
Currently, I'm writing the parser using attoparsec, and have one
question:
In MMIXAL, a string literal starts with a , followed by an arbitrary
amount of arbitrary characters excluding the newline character and
parseConstant = Reference $ try parseLocLabel
| PlainNum $ decimal
| char '#' * fmap PlainNum hexadecimal
| char '\'' * (CharLit $ notChar '\n') * char '\''
| try $ (char '' * (StringLit . B.pack $
manyTill (notChar

I hope, you understand my question.
Not sure. If I understand correctly, if you have
someParser = foo
| bar
| parseConstant
| baz
| quux
and invoke someParser on something like
\Line\nLine\
it tries baz and quux

Can you give a concrete example of the problem that you're seeing here?
