GHC.Hs.DocString

Description

An exactprintable structure for docstrings

Synopsis

Documentation

data HsDocString Source #

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 -> a

NestedDocString !HsDocStringDecorator LHsDocStringChunk

The docstring is preceded by "{-decorator" and followed by "-}" The chunk contains balanced pairs of '{-' and '-}'

GeneratedDocString HsDocStringChunk

A 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

pprHsDocString :: HsDocString -> SDoc Source #

Pretty print with decorators, exactly as the user wrote it

renderHsDocString :: HsDocString -> String Source #

Just get the docstring, without any decorators

renderHsDocStrings :: [HsDocString] -> String Source #

Just get the docstring, without any decorators Separates docstrings using "nn", which is how haddock likes to render them

exactPrintHsDocString :: HsDocString -> String Source #

Pretty print with decorators, exactly as the user wrote it

pprWithDocString :: HsDocString -> SDoc -> SDoc Source #

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
