position :: Int -> String -> Int -> Int -> PositionSource
position absoluteOffset fileName lineNumber columnNumber initializes a Position using the given arguments
Position and length of a token
mkPosLength :: Position -> Int -> PosLengthSource
unPosLength :: PosLength -> (Position, Int)Source
initPos :: FilePath -> PositionSource
initialize a Position to the start of the translation unit starting in the given file
isSourcePos :: Position -> BoolSource
returns True if the given position refers to an actual source file
position attached to built-in objects
isBuiltinPos :: Position -> BoolSource
returns True if the given position refers to a builtin definition
position used for internal errors
isInternalPos :: Position -> BoolSource
returns True if the given position is internal
adjustPos :: FilePath -> Int -> Position -> PositionSource
adjust position: change file and line number, reseting column to 1. This is usually
used for #LINE pragmas. The absolute offset is not changed - this can be done
by adjustPos newFile line . incPos (length pragma).
