type Column = Int Source #

type Line = Int Source #

type SourceName = String Source #

data SourcePos Source #

The abstract data type SourcePos represents source positions. It contains the name of the source (i.e. file name), a line number and a column number. SourcePos is an instance of the Show, Eq and Ord class.

incSourceColumn :: SourcePos -> Column -> SourcePos Source #

Increments the column number of a source position.

incSourceLine :: SourcePos -> Line -> SourcePos Source #

Increments the line number of a source position.

initialPos :: SourceName -> SourcePos Source #

Create a new SourcePos with the given source name, and line number and column number set to 1, the upper left.

newPos :: SourceName -> Line -> Column -> SourcePos Source #

Create a new SourcePos with the given source name, line number and column number.

setSourceColumn :: SourcePos -> Column -> SourcePos Source #

Set the column number of a source position.

setSourceLine :: SourcePos -> Line -> SourcePos Source #

Set the line number of a source position.

setSourceName :: SourcePos -> SourceName -> SourcePos Source #

Set the name of the source.

sourceColumn :: SourcePos -> Column Source #

the column number from a source position

sourceLine :: SourcePos -> Line Source #

the line number from a source position

sourceName :: SourcePos -> SourceName Source #

the name of the source from a position

updatePosChar :: SourcePos -> Char -> SourcePos Source #

updatePosString :: SourcePos -> String -> SourcePos Source #

The expression updatePosString pos s updates the source position pos by calling updatePosChar on every character in s, ie. foldl updatePosChar pos string.
