I think you want "vared -h ..." ?
Yep. Thanks!
A change to zshdb's command reading now has this on github (and the -e mentioned below). I still have some work to integrate better with the history but that will come later.
If the -p flag is given, the following string will be taken as the
prompt to display at the left. If the -r flag is given, the
following string gives the prompt to display at the right. If the
-h flag is specified, the history can be accessed from ZLE. If the
-e flag is given, typing ^D (Control-D) on an empty line causes
vared to exit immediately with a non-zero return value.
You can combine this with "fc -p"/"fc -P" to use a different history in
vared. See Functions/Misc/sticky-note for an example.
As for whether a descriptor is "interactive", probably the closest you
can get is "[[ -t 0 ]]" (replace 0 with the fd you're interested in).
I was right - what I had worked out on my own this isn't as robust, simple or elegant as this solution. Thanks again.
