Grammar and parsing

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

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

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

Like readFields but also return lexer warnings

ParseResult

data ParseResult a Source #

A monad with failure and accumulating errors and warnings.

runParseResult :: ParseResult a -> ([PWarning], Either (Maybe Version, NonEmpty PError) a) Source #

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

parseString Source #

Arguments

:: (ByteString -> ParseResult a)	File contents to final value parser
-> Verbosity	Verbosity level
-> String	File name
-> ByteString
-> IO a

parseWarning :: Position -> PWarnType -> String -> ParseResult () Source #

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

parseWarnings :: [PWarning] -> ParseResult () Source #

Add multiple warnings at once.

parseFailure :: Position -> String -> ParseResult () Source #

Add an error, but not fail the parser yet.

For fatal failure use parseFatalFailure

parseFatalFailure :: Position -> String -> ParseResult a Source #

Add an fatal error.

Warnings

data PWarnType Source #

Type of parser warning. We do classify warnings.

Different application may decide not to show some, or have fatal behaviour on others

Note: the first argument should return Strings without newlines and properly prefixes (with --) to count as comments. This unsafety is left in place so one could generate empty lines between comment lines.
