In 2010 I started a project to bring such functionality to Vim. The project
implements the function popuplist with the following interface:
let items = ['Item 1', 'Item 2', 'Item 3']
let opts = {'current': 1 }
let rv = popuplist(items, 'Example', opts)
if rv.status == 'accept'
echo items[rv.current]
endif
The code is in my clone of Vim on branch vim-popuplist:
https://github.com/mmahnic/vim/tree/vim-popuplist
The core is in popuplst.c and various extensions are in puls_x files. The
system is described in runtime/doc/popuplist.txt. The problem for the adoption
in Vim is that it is written in "Object Oriented" C and has to go through a
"precompiler" written in Python (mmoocc.py).
There are various modes for filtering the list: fuzzy matching,regex matching
and word matching. Expressions can also be highlighted without filtering.
Here are some screenshots from the old Python version:
http://vimuiex.sourceforge.net/screenshot/vxrecentfile.png.html. The C version
looks similar.
There are also some known bugs that would have to be fixed, but I haven't had
the time to do it in the last few years although I use it daily through the
vimuiex library. It can run processes (like grep) in the background so the list
of items is growing while the user already explores it; this functionality
should be modified to use channels.
If there is interest the code could probably be used as a start.
