Subject: promptcr workaround
Date: Tue, 01 Mar 2005 00:17:43 -0800 [thread overview]
Message-ID: <quack.20050301T0017.874qfvbx08@quack.cs.berkeley.edu> (raw)
I've always been unsatisfied with the answer to FAQ entry
3.23 "How do I prevent the prompt overwriting output when there is
no newline?" I dislike zsh's promptcr behavior both on and off.
I don't like silently losing the last line nor having a messed-up
prompt, and didn't like adding an extra newline on every command.
Here's a way to simulate adding the \n only when necessary:
function precmd {
echo -n ${(l:$COLUMNS:::)}
}
This prints $COLUMNS spaces. Iff there's any output on the line
already, it'll wrap to somewhere on the next line. So when zsh
prints the \r it'll always erase only spaces.
