Subject: Detect typed input without swallowing characters
Date: Thu, 10 Feb 2022 22:21:44 +0100 [thread overview]
Message-ID: <CACn48Nq5hW0u9PhrTPSGOZjvohArKpVoXrGsryEM+jQpwfS-zg@mail.gmail.com> (raw)
Hi,
in Oh My Zsh we want to detect whether the user has typed characters
before showing the prompt to auto-update, so that if they have, to
skip it entirely and get them to the prompt as fast as possible.
The current solution is to detect whether there's input with `read -t
-k 1`, but this solution has the downside of swallowing one character.
I've been looking at sysread and zselect to poll stdin (fd 0), but I
believe they only tell whether stdin is ready for reading, not whether
it holds any data. These are the commands I'm using by the way:
sysread -t 0 -i 0
zselect -t 0 -r 0
Is there any way to do this or should I give up entirely?
Thanks!
Marc
