Like this: :set nolz | while 1 | e | redraw | $ | call getchar(0) | sleep 1 | endw Correction, this should have been getchar(1) not getchar(0). Addition of getchar(1) also handles resizes properly.

I can see the extra output on the bottom line. I'll look into this later. How do you see the problem with the screen resize? I am trying now to ':call getchar(0)' near 'sleep 1', and with this addition, screen resizes properly. Like this: :set nolz | while 1 | e | redraw | $ | call getchar(0) | sleep 1 | endw Without getchar(0), resize is not handled. Yakov

I can see the extra output on the bottom line. I'll look into this later. How do you see the problem with the screen resize? Originally, &lines is around 50. Screenshot before resize is http://www.wikiupload.com/download_page.php?id=16428 (before-resize.gif). This is normal screen. Here is how I resize: I resize screen height down to 10. Then I resize height back to approximately original height. Here is screenshot after resize (I also give it several seconds of time, but it never really recovers): http://www.wikiupload.com/download_page.php?id=16429 (after-resize.gif).

screen update problem during periodic file "refresh"
I see several problems (that I can't explain) in the vim "refresh"-loop watching the growing file (a-la 'tail -f'). Vim commands are below. Problem #1: There is unexpected output on the bottom line (lines of the file is echoed on the bottom line). Why ? Problem #2: When you vertically resize the xterm window, vim screen is corrupted and never repainted properly. Problem #3: Sometimes, when I press Ctrl-C to quit the loop, vim is in ex mode and responds 'Type :quit to exit Vim' Why ? Problem #4: Since vim repaints properly when waiting for chars, I'd like to put getchartimeout(1000) in place of sleep 1. Do we have getchar() with timeout ? To see the demonstration: 1. In one window, create growing file using these shell command: % while :; do date >>1; sleep 1; done 2. In another window: vim -u NONE ~/xxx :set nolz | while 1 | e | redraw | $ | sleep 1 | endw " notice unexpected output on the bottom line " try to resize screen. It is not restored properly. " Press Ctrl-C to quit. Sometimes, vim quits the loop properly. " Sometime, vim does not quit the loop, stays in ex mode. " (Type :quit to exit Vim) (This command sequence must be not perfect but it demonstrates the problem). Yakov
