Hi,

I'm using the Parsec library to parse strings for a small experimental language. I'd like to decorate each node in the abstract syntax tree with a pair (Int, Int) that represents the line and column number in the strings. Unfortunately, the SourcePos class in the Parsec library is abstract and I cannot extract the line and column numbers from a SourcePos value. What are my options?

What about these? type Column = Int type Line = Int sourceColumn :: SourcePos -> Column sourceLine :: SourcePos -> Line Regards, Tomasz -- .signature: Too many levels of symbolic links
