### Completion
The following can replace fish completion menu with fzf. Because of a [fish bug](https://github.com/fish-shell/fish-shell/issues/3469) this will fail on variables and other elements that need escaping (or not).
```
function fzf-complete -d 'fzf completion and print selection back to commandline'
set -l complist (complete -C(commandline -c))
set -l result
string join -- \n $complist | sort | eval (__fzfcmd) -m --tiebreak=index --select-1 --exit-0 --header '(commandline)' | cut -f1 | while read -l r; set result $result $r; end
for i in (seq (count $result))
set -l r $result[$i]
## We need to escape the result.
switch (string sub -s 1 -l 1 -- (commandline -t))
case "'"
commandline -t -- (string escape -- (eval "printf '%s' '$r'"))
case '"'
set -l quoted (string escape -- (eval "printf '%s' '$r'"))
set -l len (string length $quoted)
commandline -t -- '"'(string sub -s 2 -l (math $len - 2) (string escape -- (eval "printf '%s' '$r'")))'"'
case '~'
commandline -t -- (string sub -s 2 (string escape -n -- (eval "printf '%s' '$r'")))
case '*'
commandline -t -- (string escape -n -- (eval "printf '%s' '$r'"))
end
[ $i -lt (count $result) ]; and commandline -i ' '
end
commandline -f repaint
end
```
