default completion function

default completion function

Hello everybody, I would like to make the completion function _gnu_generic
the default completion for those functions that don't have something more
specific attached to them.
If I use:

zstyle ':completion:*' completer _gnu_generic

a command like docker that has his own completion loses it and gets
completed with _gnu_generic.
How can I set a default like that without overwriting existing more
specific completion?

thanks

The obvious way (so probably this is too simple) is to override the
function _default, the normal version of which you'll find in your
$fpath.  As long as your function starts with "#compdef -default-" and
is earlier in your $fpath it should be used in preference.

I wouldn't recommend that.  The _gnu_generic function falls back on
_default so this potentially creates infinite recursion.

Much better:  compdef _gnu_generic -default-
