debugEnabledFlag :: Bool

Global switch to enable debug tracing in ghc-exactprint Delta / Print

debugPEnabledFlag :: Bool

Global switch to enable debug tracing in ghc-exactprint Pretty

debug :: c -> String -> c

Provide a version of trace that comes at the end of the line, so it can easily be commented out when debugging different things.

debugP :: String -> c -> c

Provide a version of trace for the Pretty module, which can be enabled separately from debug and debugM

debugM :: Monad m => String -> m ()

warn :: c -> String -> c

isGoodDelta :: DeltaPos -> Bool

A good delta has no negative values.

ss2delta :: Pos -> RealSrcSpan -> DeltaPos

Create a delta from the current position to the start of the given RealSrcSpan.

ss2deltaEnd :: RealSrcSpan -> RealSrcSpan -> DeltaPos

create a delta from the end of a current span. The +1 is because the stored position ends up one past the span, this is prior to that adjustment

ss2deltaStart :: RealSrcSpan -> RealSrcSpan -> DeltaPos

create a delta from the start of a current span. The +1 is because the stored position ends up one past the span, this is prior to that adjustment

pos2delta :: Pos -> Pos -> DeltaPos

Convert the start of the second Pos to be an offset from the first. The assumption is the reference starts before the second Pos

undelta :: Pos -> DeltaPos -> LayoutStartCol -> Pos

Apply the delta to the current position, taking into account the current column offset if advancing to a new line

undeltaSpan :: RealSrcSpan -> AnnKeywordId -> DeltaPos -> AddEpAnn

adjustDeltaForOffset :: LayoutStartCol -> DeltaPos -> DeltaPos

ss2pos :: RealSrcSpan -> Pos

ss2posEnd :: RealSrcSpan -> Pos

ss2range :: SrcSpan -> (Pos, Pos)

rs2range :: RealSrcSpan -> (Pos, Pos)

rs :: SrcSpan -> RealSrcSpan

range2rs :: (Pos, Pos) -> RealSrcSpan

badRealSrcSpan :: RealSrcSpan

spanLength :: RealSrcSpan -> Int

isPointSrcSpan :: RealSrcSpan -> Bool

Checks whether a SrcSpan has zero length.

orderByKey :: [(RealSrcSpan, a)] -> [RealSrcSpan] -> [(RealSrcSpan, a)]

Given a list of items and a list of keys, returns a list of items ordered by their position in the list of keys.

sortComments :: [Comment] -> [Comment]

Sort, comparing without span filenames, for CPP injected comments with fake filename

sortEpaComments :: [LEpaComment] -> [LEpaComment]

Sort, comparing without span filenames, for CPP injected comments with fake filename

mkKWComment :: AnnKeywordId -> EpaLocation -> Comment

Makes a comment which originates from a specific keyword.

isKWComment :: Comment -> Bool

Detects a comment which originates from a specific keyword.

noKWComments :: [Comment] -> [Comment]

sortAnchorLocated :: [GenLocated Anchor a] -> [GenLocated Anchor a]

dpFromString :: String -> DeltaPos

Calculates the distance from the start of a string to the end of a string.
