Script for adding curent path to `zoxide` complete

I like using zoxide as a replacement for cd, so I also like having the tab complete have the current dirs in the directory in addition to the zoxide complete.

I'm not too sure in my own nushell code, so I don't want to make a pull request, but I'd like to share how I added the current dir to my zoxide complete.

let zoxide_completer = {|spans|
  let path = ($spans.1 | glob $"\(?i\)($in)*" | where {path type | $in == dir} | each {path relative-to (glob "." | first)})
  let zoxide = ($spans | skip 1 | zoxide query -l ...$in | lines | where {|x| $x != $env.PWD})
  ($zoxide | prepend $path)
}

this addition to the completer allows you to do this:

The first two entries are from the current dir, the second two are from zoxide.

There are a few places this script can fail. Firstly being with the path relative-to command. It will straight up fail if the prefix can't be found. I have an immutable distro so my /home/user folder is linked to the /var/home/user folder. This makes it unreliable to use $env.PWD as this will be different from what glob returns, so I just glob . instead, lol. Also, I'm unsure if spans always return more than one element. It seems to work with no arguments, but I don't know how it works.

I'm sure there are better ways of doing this and such, but it works for me. Just wanted to share if anyone wanted to refine it and add it to the external_completers.md file.

Beginne mit dem Lesen von external_completers.md und prüfe, wie Beispiele für externe Completer dargestellt werden. Validiere das vorgeschlagene Nushell-Snippet einschließlich der im Issue erwähnten Fälle ohne Argumente und mit Pfadpräfix. Als abgeschlossen gilt die Aufgabe, wenn das dokumentierte Beispiel zuverlässig Einträge aus dem aktuellen Verzeichnis neben zoxide-Vervollständigungen hinzufügt.
