Summary: Some general parsing utilities used for parsing textual chord representations.


Top level parsers

parseData :: (ListLike s a, Show a) => P (Str a s LineColPos) b -> s -> b Source #

Top-level parser that ignores error-reporting, regardless of there were error in the parse

parseDataWithErrors :: (ListLike s a, Show a) => P (Str a s LineColPos) b -> s -> (b, [Error LineColPos]) Source #

Top-level parser that returns both the result as well as a (possibly empty) list of error-corrections.

parseDataSafe :: (ListLike s a, Show a, Show s) => P (Str a s LineColPos) b -> s -> b Source #

This is identical to parseData however it will throw an error when the the list with parsing errors is not empty. No, this will not make your program more safe. However, in certain cases you really want to be sure that parsing has finished without errors. In those cases you should use parseDataSafe.

Some general parsers

pString :: (ListLike state a, IsLocationUpdatedBy loc a, Show a, Eq a) => [a] -> P (Str a state loc) [a] Source #

Parses a specific string

pLineEnd :: Parser String Source #

Parses UNIX and DOS/WINDOWS line endings including trailing whitespace

pManyTill :: P st a -> P st b -> P st [a] Source #

Parses an arbitrary times the first parsing combinator until the parsing second parsing combinator is encountered. The result of the second parsing combinator is ignored.
