valuerecoverWith :: ParseResult src a -> a -> ParseResult src a

Recover the parse result, so we can proceed parsing. runParseResult will still result in Nothing, if there are recorded errors.

valueparseWarning :: Position -> PWarnType -> String -> ParseResult src ()

Add a warning. This doesn't fail the parsing process.

valueparseWarnings :: [PWarning] -> ParseResult src ()

Add multiple warnings at once.

valueparseFailure :: Position -> String -> ParseResult src ()

Add an error, but not fail the parser yet.

For fatal failure use parseFatalFailure

valueparseFatalFailure :: Position -> String -> ParseResult src a

Add an fatal error.

valueparseFatalFailure' :: ParseResult src a

valuegetCabalSpecVersion :: ParseResult src (Maybe Version)

Get cabal spec version.

valuesetCabalSpecVersion :: Maybe Version -> ParseResult src ()

Set cabal spec version.

valuewithoutWarnings :: ParseResult src a -> ParseResult src a

Forget ParseResults warnings.

valueliftParseResult

Chain parsing operations that involve IO actions.

valuewithSource :: src -> ParseResult src a -> ParseResult src a
