I have my own tool for selecting paths
(github.com/MarcWeber/path-selector).
I'd like to use it within ZSH.
I came up with this:
http://dpaste.com/550269/
(You can replace line 78 by 79)
select-one first uses echo to show the alternatives, then read to get
the item index from the user.
However because echo shows many lines the code copied from
modify-current-argument get's confused.
ctl-l redraws the current line but drops some history.
zle -R does not help
Is there an even better way to implement select-one?
Pointing me to sample code will be enough.

I'd probably just do this:
_my_quickpath() {
[[ -z "${words[CURRENT]}" ]] && (( CURRENT > 0 && --CURRENT ))
compadd -Q -U $($HQUICKFILE --echo "${words[CURRENT]}")
}
compdef -k _my_quickpath menu-select ^g
I'm not entirely sure about the --CURRENT part but you get the idea.
If you insist on doing it yourself without using a completion widget,
then you need to replace line 24-25 of select-one with something along
the lines of
local -a replies
for i ({1..$#@}) { replies+=( "$i: ${${@[$i]}#$strip}" ) }
read-from-minibuffer "$(print -c "${replies[@]}")"$'\n'
And then replace other calls to "read $opt" with a similar call to
read-from-minibuffer. (Oh, it needs to be autoloaded first.)
This of course renders select-one unusuable outside of ZLE, so you'll
have to make a new function out out it if you want select-one for any
other purpose.
