uniform representation of source file positions
position :: Int -> String -> Int -> Int -> Position Source #
position absoluteOffset fileName lineNumber columnNumber initializes a Position using the given arguments
posColumn :: Position -> Int Source #
column in the preprocessed file. Inaccurate w.r.t. to the original file in the presence of preprocessor macros.
initPos :: FilePath -> Position Source #
initialize a Position to the start of the translation unit starting in the given file
isSourcePos :: Position -> Bool Source #
returns True if the given position refers to an actual source file
builtinPos :: Position Source #
position attached to built-in objects
isBuiltinPos :: Position -> Bool Source #
returns True if the given position refers to a builtin definition
internalPos :: Position Source #
position used for internal errors
isInternalPos :: Position -> Bool Source #
returns True if the given position is internal
adjustPos :: FilePath -> Int -> Position -> Position Source #
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).
