(==) :: RelativePos -> RelativePos -> Bool

(/=) :: RelativePos -> RelativePos -> Bool

Show RelativePos

Defined in Ormolu.Utils

Methods

showsPrec :: Int -> RelativePos -> ShowS

show :: RelativePos -> String

showList :: [RelativePos] -> ShowS

attachRelativePos :: [a] -> [(RelativePos, a)]

Attach RelativePoses to elements of a given list.

combineSrcSpans' :: NonEmpty SrcSpan -> SrcSpan

Combine all source spans from the given list.

notImplemented :: String -> a

Placeholder for things that are not yet implemented.

showOutputable :: Outputable o => o -> String

Pretty-print an Outputable thing.

splitDocString :: HsDocString -> [Text]

Split and normalize a doc string. The result is a list of lines that make up the comment.

typeArgToType :: LHsTypeArg p -> LHsType p

Get LHsType out of LHsTypeArg.

unSrcSpan :: SrcSpan -> Maybe RealSrcSpan

Get RealSrcSpan out of SrcSpan if the span is “helpful”.

incSpanLine :: Int -> SrcSpan -> SrcSpan

Increment line number in a SrcSpan.

separatedByBlank :: (a -> SrcSpan) -> a -> a -> Bool

Do two declarations have a blank between them?

separatedByBlankNE :: (a -> SrcSpan) -> NonEmpty a -> NonEmpty a -> Bool

Do two declaration groups have a blank between them?

onTheSameLine :: SrcSpan -> SrcSpan -> Bool

Return True if one span ends on the same line the second one starts.

removeIndentation :: String -> (String, Int)

Remove indentation from a given String. Return the input with indentation removed and the detected indentation level.

groupBy' :: (a -> a -> Bool) -> [a] -> [NonEmpty a]

A generalisation of groupBy to functions which aren't equivalences - a group ends when comparison fails with the previous element, rather than the first of the group.
