Haskell Documentation String
Rich structure to support exact printing The location around each chunk doesn't include the decorators
Constructors
MultiLineDocString !HsDocStringDecorator !(NonEmpty LHsDocStringChunk)The first chunk is preceded by "-- decorator" and each following chunk is preceded by "--" Example: -- | This is a docstring for
foo. It is the line with the decorator|and is always included -- This continues that docstring and is the second element in the NonEmpty list foo :: a -> aNestedDocString !HsDocStringDecorator LHsDocStringChunkThe docstring is preceded by "{-decorator" and followed by "-}" The chunk contains balanced pairs of '{-' and '-}'
GeneratedDocString HsDocStringChunkA docstring generated either internally or via TH Pretty printed with the '-- |' decorator This is because it may contain unbalanced pairs of '{-' and '-}' and not form a valid NestedDocString

Create a HsDocString from a UTF8-encoded ByteString.
Pretty print with decorators, exactly as the user wrote it
Just get the docstring, without any decorators
Just get the docstring, without any decorators Separates docstrings using "nn", which is how haddock likes to render them
Pretty print with decorators, exactly as the user wrote it
Annotate a pretty printed thing with its doc The docstring comes after if is HsDocStringPrevious Otherwise it comes before. Note - we convert MultiLineDocString HsDocStringPrevious to HsDocStringNext because we can't control if something else will be pretty printed on the same line
