position :: Int -> String -> Int -> Int -> Position #

`position absoluteOffset fileName lineNumber columnNumber` initializes a `Position` using the given arguments

type PosLength = (Position, Int) #

Position and length of a token

posFile :: Position -> String #

source file

posRow :: Position -> Int #

row (line) in the original file. Affected by #LINE pragmas.

posColumn :: Position -> Int #

Deprecated: column number information is inaccurate in presence of macros - do not rely on it.

column in the preprocessed file. Inaccurate w.r.t. to the original file in the presence of preprocessor macros.

posOffset :: Position -> Int #

absolute offset in the preprocessed file

initPos :: FilePath -> Position #

initialize a Position to the start of the translation unit starting in the given file

isSourcePos :: Position -> Bool #

returns `True` if the given position refers to an actual source file

nopos :: Position #

no position (for unknown position information)

isNoPos :: Position -> Bool #

returns `True` if the there is no position information available

builtinPos :: Position #

position attached to built-in objects

isBuiltinPos :: Position -> Bool #

returns `True` if the given position refers to a builtin definition

internalPos :: Position #

position used for internal errors

isInternalPos :: Position -> Bool #

returns `True` if the given position is internal

incPos :: Position -> Int -> Position #

advance column

retPos :: Position -> Position #

advance to next line

adjustPos :: FilePath -> Int -> Position -> Position #

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)`.

incOffset :: Position -> Int -> Position #

advance just the offset

class Pos a where #

class of type which aggregate a source code location

Minimal complete definition

posOf
