[news.software.b] Xrefs in vn

mark@intek01.UUCP (Mark McWiggins) (03/13/89)

I'm a vn user, and generally quite happy with it.  I just wish it
did cross-referencing, so i wouldn't see articles I've already read.

Since cross-posted articles are just links to the same file, wouldn't 
just keeping a list of inodes found handle this?  Have you already
done this?

This seems so trivial there may be something wrong with it.  I'd
like to hear from anyone who can see a flaw in this technique, or
who's already hacked vn to do it.  If there's no reply from either
camp within a week, I'll try it out and post the results.

Thanks in advance.

This is terribly un-general.  What happens if you ever move your news
spool area to a new filesystem, need to dump/newfs/restore your
current one?  (All the inodes will change, and you'll lose track.)
What happens if you ever want to begin using NNTP? (inode information
won't be available at all.)

If you're going to go to the trouble to add cross-referencing, you may
as well do it by the same mechanisms that the other, more modern
newsreaders use.  Don't intentionally tie yourself down with yet
another newly-invented loss of generality!
