I've been dealing with somethign for a few days and have looked around for
discussions about it, but can't seem to find any. My instincts are that the root
of the issue is something that people on this list are most likely to be able to
help with, so here I go...
Since upgrading to Leopard, I've noticed the following behavior, which I can't
understand the root of or how to change. Working from a 80x24 terminal (I've now
reproduced what follows in all of iTerm.app, Terminal.app, and xterm under X11),
if I open a multipage file (in vim or even with less) and page around a bit,
then scroll back through the terminal buffer, the pages in the terminal buffer
display the page redraws from vim or less.
In previous versions of mac os, when I paged up through the terminal buffer, I
would get the last lines printed to the terminal before opening (or resuming to
the foreground) the editor, but not all of the redraws performed by the editor
itself.
I found this very useful, since I could ctrl-z out of vim, run a compile, fg
back into the editor, and page up through the terminal buffer to go through the
compiler output, page around in my editor and do some work, ctrl-z back out and
recompile, etc. Now I can't do this, because the last buffer's worth of compiler
output is seemingly overwritten by the newly opened (or newly resumed) editor
contents.
I'm not sure if this is an ncurses thing or maybe some environment variable I'm
not setting correctly. This seems like the kind of thing that must be pretty
basic and I'm somehow missing the way to change it, so I'm hoping someone here
can help?
