uniform representation of source file positions; the order of the arguments is important as it leads to the desired ordering of source positions
initPos :: FilePath -> PositionSource
initialize a Position to the start of the translation unit starting in the given file
posFile :: Position -> StringSource
get the source file of the specified position. Fails unless isSourcePos pos
.
posRow :: Position -> IntSource
get the line number of the specified position. Fails unless isSourcePos pos
posColumn :: Position -> IntSource
get the column of the specified position. Fails unless isSourcePos pos
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
tabPos :: Position -> PositionSource
advance column to next tab positions (tabs are considered to be at every 8th column)
