type FieldName = ByteString

Grammar and parsing

readFields :: ByteString -> Either ParseError [Field Position]

Parse cabal style ByteString into list of Fields, i.e. the cabal AST.

readFields assumes that input ByteString is valid UTF8, specifically it doesn't validate that file is valid UTF8. Therefore bytestrings inside returned Field will be invalid as UTF8 if the input were.

>>> readFields "foo: \223"
Right [Field (Name (Position 1 1) "foo") [FieldLine (Position 1 6) "\223"]]

readFields won't (necessarily) fail on invalid UTF8 data, but the reported positions may be off.

You may get weird errors on non-UTF8 input, for example readFields will fail on latin1 encoded non-breaking space:

>>> isLeft (readFields "\xa0 foo: bar")
True

That is rejected because parser thinks \xa0 is a section name, and section arguments may not contain colon. If there are just latin1 non-breaking spaces, they become part of the name:

>>> readFields "\xa0\&foo: bar"
Right [Field (Name (Position 1 1) "\160foo") [FieldLine (Position 1 7) "bar"]]

The UTF8 non-breaking space is accepted as an indentation character (but warned about by readFields').

>>> readFields' "\xc2\xa0 foo: bar"
Right ([Field (Name (Position 1 3) "foo") [FieldLine (Position 1 8) "bar"]],[LexWarning LexWarningNBSP (Position 1 1)])

readFields' :: ByteString -> Either ParseError ([Field Position], [LexWarning])

Like readFields but also return lexer warnings.

Destruct a ParseResult into the emitted warnings and either a successful value or list of errors and possibly recovered a spec-version declaration.

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

parseWarnings :: [PWarning] -> ParseResult ()

Add multiple warnings at once.

Add an error, but not fail the parser yet.

For fatal failure use parseFatalFailure

parseFatalFailure :: Position -> String -> ParseResult a

Add an fatal error.
