Add a function to get column number? #5

How about adding a function to get the column number of a line? We now have a function to get the line number, how about the column number?

Thanks for your suggestion. However, a member returning a column number is in practice so little used, that adding it to the standard facilities is not really worth the effort.

If monitoring column numbers is something you require, a simple solution would be to provide the gegerated scanner with an Input class of your own design, and count columns in its get' member. Be sure to update column numbers inreRead' and in the constructors.

But I'll keep your suggestion in mind. I might add it to a future version of flexc++.

Thanks again,
