Instances
runParsecParser :: ParsecParser a -> FilePath -> FieldLineStream -> Either ParseError a #
Run ParsecParser with cabalSpecLatest.
simpleParsec :: Parsec a => String -> Maybe a #
Parse a String with lexemeParsec.
lexemeParsec :: (CabalParsing m, Parsec a) => m a #
parsec could consume trailing spaces, this function will consume.
eitherParsec :: Parsec a => String -> Either String a #
Parse a String with lexemeParsec.
explicitEitherParsec :: ParsecParser a -> String -> Either String a #
Parse a String with given ParsecParser. Trailing whitespace is accepted.
CabalParsing & warnings

Type of parser warning. We do classify warnings.
Different application may decide not to show some, or have fatal behaviour on others

| PWTQuirkyCabalFile | legacy cabal file that we know how to patch |
| PWTDoubleDash | Double dash token, most likely it's a mistake - it's not a comment |
| PWTMultipleSingularField | e.g. name or version should be specified only once. |
