[Q] Reload keybinding to retrigger completion from already running fzf

[shadarim]

FZF has a reload action, which would execute a given command and load the results back in fzf. How do I replicate this with fzf-tab ?

Example use would be with:
kill -9 <tab>
and from within the completion hit Ctrl-R to reload the process list.

I can bind the reload as follows:
zstyle ':fzf-tab:complete:*' fzf-bindings 'ctrl-r:reload(ps -ef)'
and this does indeed reload the process list, but with some unwanted side effects:

• list is not searchable anymore
• color changes
• selecting an entry is not outputting anything into the terminal anymore.

I guess this is because the newly generated list is not fed into fzf-tab as completions ?
Any hints on how to get the desired behavior ?

This is very hard.

You have to spawn a new zsh process to generate the new reuslt, and feed ${TMPPREFIX:-/tmp/zsh}-fzf-tab-$USER/completions.$$ to fzf.
