I would dearly like to be able to replace ex by a more
comfortable older version
eg
not wiping image of recent changes on screen
on exit.
I'm not 100% sure how to do this one. This is likely a terminal
thing. Perhaps you can monkey with the settings as described in
:help xterm-save-screen
where it sounds like the "NOTE 2" at the bottom of that section
describes what you want:
:set t_ti= t_te=
I'm ambivalent about this option, as sometimes I want it, and
sometimes I don't, and I don't think about it until I quit and
find that it's not what I wanted. Some machines I use preserve
the original screen (using the alternate screen for vim), and
some don't. I've just learned to shrug that one off :)
"undo" to "undo" just the last change by
default - not all changes since start of session.
Vim7's undo is mind-blowingly more powerful than any other
software I've used (except maybe VCS software such as
RCS/Subversion/Mercurial/etc). It shouldn't undo all changes
since the start of the session (assuming by "session", you mean
since opening the file). Vim certainly allows you to return to
the old-school way of doing things, as described at
:help undo-two-ways
and following section for how Vim treats undo blocks as well.
etc
Without more details on this "etc", it's hard to point you in the
right direction. However, this mailing list is a friendly place,
so if you encounter more questions, feel free to ask them here
and the list will try and help you out.
I get accused of being the list's resident Ex junkie, so
hopefully I can help. :) I'm likely one of the scant few who
still wants Vim to support true open mode (":help :open"). Not
urgently, but there are times it would have been handy.
Fortunately, I've got some older versions of vi that do support
it for those scarse occasions I want it.
