Documentation
Class for parsing with parsec. Mainly used for .cabal file fields.
For parsing .cabal like file structure, see Distribution.Fields.

Instances
runParsecParser :: ParsecParser a -> FilePath -> FieldLineStream -> Either ParseError a Source #
Run ParsecParser with cabalSpecLatest.
runParsecParser' :: CabalSpecVersion -> ParsecParser a -> FilePath -> FieldLineStream -> Either ParseError a Source #
Like runParsecParser but lets specify CabalSpecVersion used.
Since: Cabal-3.0.0.0
simpleParsec :: Parsec a => String -> Maybe a Source #
Parse a String with lexemeParsec.
lexemeParsec :: (CabalParsing m, Parsec a) => m a Source #
parsec could consume trailing spaces, this function will consume.
eitherParsec :: Parsec a => String -> Either String a Source #
Parse a String with lexemeParsec.
explicitEitherParsec :: ParsecParser a -> String -> Either String a Source #
Parse a String with given ParsecParser. Trailing whitespace is accepted.
CabalParsing and and diagnostics
class (CharParsing m, MonadPlus m, MonadFail m) => CabalParsing m where Source #
Parsing class which
- can report Cabal parser warnings.
- knows

Warnings
Type of parser warning. We do classify warnings.
Different application may decide not to show some, or have fatal behaviour on others
Constructors
| PWTOther | Unclassified warning |
| PWTUTF | Invalid UTF encoding |
| PWTBoolCase |
|
| PWTVersionTag | there are version with tags |
| PWTNewSyntax | New syntax used, but no |

| 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. |
| PWTBuildTypeDefault | Workaround for derive-package having build-type: Default. See https://github.com/haskell/cabal/issues/5020. |
