data Posn Source

Source positions contain a filename, line, column, and an inclusion point, which is itself another source position, recursively. Constructors Pn String !Int !Int (Maybe Posn) Instances Eq Posn Show Posn

newfile :: String -> Posn Source

Constructor

addcol :: Int -> Posn -> Posn Source

Updates

newline :: Posn -> Posn Source

tab :: Posn -> Posn Source

newlines :: Int -> Posn -> Posn Source

newpos :: Int -> Maybe String -> Posn -> Posn Source

cppline :: Posn -> String Source

cpp-style printing

filename :: Posn -> String Source

lineno :: Posn -> Int Source

Projections

directory :: Posn -> FilePath Source
