Thanks Alan. There were a few things I did not tell you about what I
was doing (I was a bit fried), and I now have a working solution to
my problem. Here it is for all to enjoy.
Basically, I was attempting to implement a client side diff for the
Macintosh using MacCVS. This will eventually be an enhancement for
my CWCVS CodeWarrior integration tool. MacCVS does a number of
things under the hood, most notably expanding resource forks, so the
-p option was not really what I was looking for (and I believe that
Alex stated recently that it does not work correctly in
MacCVS/WinCVS). checkout also occurred to me, but it seems to
produce deep trees and CVS directories which I would then have to
wade through and clean up. Building the command would also be fairly
involved (I actually did it but it was ugly).
The fairly elegant solution I came up with on the bike ride home
(isn't that when we always thing of the Good Stuff?) was to simply
move the local file to a temp directory, do a cvs update <file> and
swap the files! I can then diff the files to my heart's content. I
have this solution up and running now and visual/resource diffs from
cvs are now in the tool.
I suspect that there are a few glitches still to be worked out
(changing versions etc. cvs update -r<rev> <file> may be better) but
this is looking pretty good right now.
Anyway, thanks for taking the time to respond.
