Re: extents and insert-before-markers

Not particularly. I've been trying to understand the interaction between the "little dance" vm does when it updates summary entries, and the extents I'm putting on top of them. (It's taken me 11 years to get this right.) But now I understand that it works because I'm resetting my extents at every possible opportunity, rather than because of any cunning interaction. I suppose the general case I have in mind is where you have two extents covering adjacent fields: xxxxxyyyyyy and if point is at the first y, there's a clear distinction between adding to the end of field x, and adding to the beginning of field y. If you were using markers to track the fields (as vm does), then insert-before-markers and insert are the way you'd do it. But with extents would the only possibility be to change the openness each time? _______________________________________________ XEmacs-Beta mailing list XEmacs-Beta(a)xemacs.org http://lists.xemacs.org/mailman/listinfo/xemacs-beta
