unmodified :: Bool

modified :: Bool

nullSrcSpan :: SrcSpan

getSrcSpan :: Data t => t -> Maybe SrcSpan

Get the first SrcSpan found, in top down traversal

prettyprintPatList :: (t -> String) -> Bool -> [t] -> String

getGhcLoc :: SrcSpan -> (Int, Int)

gets the (row,col) of the start of the GHC.SrcSpan, or (-1,-1) if there is an GHC.UnhelpfulSpan

getGhcLocEnd :: SrcSpan -> (Int, Int)

gets the (row,col) of the end of the GHC.SrcSpan, or (-1,-1) if there is an GHC.UnhelpfulSpan

getLocatedStart :: GenLocated SrcSpan t -> (Int, Int)

getLocatedEnd :: GenLocated SrcSpan t -> (Int, Int)

ghcSpanStartEnd :: SrcSpan -> ((Int, Int), (Int, Int))

getStartEndLoc :: Data t => t -> (SimpPos, SimpPos)

startEndLocGhc :: Located b -> (SimpPos, SimpPos)

emptyList :: [t] -> Bool

Get around lack of instance Eq when simply testing for empty list TODO: get rid of this in favour of null built in fn

nonEmptyList :: [t] -> Bool
