Autocomplet with compdef _precommand

Autocomplet with compdef _precommand

Hello,

I use zsh (5.0.7) with the autocd option. I create a function start() that
will run another command :

function start (){
    "$@" &> /dev/null &
}

And I add this line to have autocomplet :

compdef _precommand start

But when I run, for example "start ssh example.com" zsh want replace "ssh"
by ".ssh/" (if I am in $HOME). I think that is because autocd change the
behaviour of _precommand.

How can I use a autocomplet like p_precommand but without the autocd
behavur ?

Thanks for your help!

Unfortunately this is a little tricky.

The easiest thing might be this:

    _start () {
	setopt localoptions noautocd
	_precommand "$@"
    }
    compdef _start start

More generically, the only zstyle that modifies autocd behavior is for
the "-command-" special context, so you have to use "zstyle -e" with
an evaluated test that determines whether "start" was the precommand
word AND whether the tags are being looked up for "cd":

    zstyle -e :completion::complete:-command-:: tag-order \
      '(( $precommands[(I)start] && $funcstack[(I)_cd] )) && reply=(-)'

Question for zsh-workers:  Is it worth adding a style to _precommand
to selectively turn off autocd?  If so, what should it be called?

Isn't that already possible? —

    zstyle -e :completion::complete:-command-:: tag-order \
      '(( $precommands[(I)start] )) && reply=("!local-directories" -)'

It would be nice not to need to use -e and to know about $precommands.
E.g. I was asking about something like

    zstyle :completion::complete:precommand-start:: autocd off

Or perhaps

    zstyle :completion::complete:precommand-start:: localoptions noautocd

which would be a more generic style name that other cases might use. But
what to make the context is also a problem.
