hey i recall seeing this in a blog just found it again but

$ echo '' | fzf --print-query --preview 'echo "a\nb\nc\nd" | awk {q}'

https://github.com/pawelduda/fzf-live-repl

Also Regex is possible

i haven't developed it past concept but the plan was to take whatever successful matching regex pattern i made saving it and for a proper filter later in the script. (also this was based off someone elese's work just cant remember where i picked it up)

declare gvar=''
declare Fvar=''
if [[ -z "$1" ]]; then
  Fvar='.'; else
  Fvar="$1"
fi
if [[ -z "$2" ]]; then
  gvar='.'; else
  gvar="$2"
fi
grep_flag_available="rg '{q}' ./ --color=always --colors=match:fg:12 --no-filename"
fd -uu -t f "$Fvar" | rg "$gvar" --no-filename | fzf --phony \
  --preview="nvimpager -c {} | $grep_flag_available"
unset gvar
unset Fvar
