When I run vim in a win32 console window, after I exit I end up with a bunch of junk on the screen - old command output, etc, because cmd doesn't clear line contents when scrolling down. I've included an example below:
Is there a way to make vim clear the whole screen buffer (not just the part that is visible), either when starting it or on exit? Or to save the entire state (buffer contents, scroll position, and cursor position) and restore afterward?
On further investigation, the restorescreen option was being set incorrectly in my vimrc.
I had this code (I don't know where I got it):
if exists(&restorescreen)
if has("win32")
set restorescreen
else
set norestorescreen
endif
else
set t_ti= t_te=
endif
but exists(&restorescreen) actually evaluates to 0.
if &restorescreen if you want tho check if restorescreen is set, or if exists('&restorescreen') if you want to find out if there is an option named restorescreen (but that should always return 1, since said option is always compiled in).
