Ignore commands if autocomplete to directory is possible

I am an old loyal user of ZSH but this is my first community mail. Pardon
me for any errors.

I am using setopt auto_cd. But when autocompleting for directories, i want
that first preference is to be given to directories than to commands. Which
means, if directory is present that matches the substring then zsh should
not search for commands.

For examples, if i type 'ex' and then press <tab> and an 'examples'
directory was present it should get autocompleted. If 'examples' directory
is not there, then it should options for 'exit' 'exec' etc commands. This
would make cd'ing to directories much more faster.

There should be some neat zstyle completion for this, but i am not able to
figure that out. Closest related thread was : disable substring match on
command name <http://www.zsh.org/mla/users/2014/msg00279.html>. But it was
hard for me to tweak it to my needs.

Is there some good completion style possible for this?

PS: My completion zstyle is currently using oh-my-zsh's
completion.zsh<https://github.com/robbyrussell/oh-my-zsh/blob/master/lib/completion.zsh>

Thanks.

Hmm.  Ordinarily you'd do this with the tag-order style like

    # Note this does not actually work
    zstyle ':completion:*:-command-::' tag-order \*-directories

(the "everything else" is implied if no directories match).  However,
this doesn't work for autocd because the _autocd function explicitly
calls _command_names before testing the autocd option and then calling
_cd.  So there's no way to exclude command names with a style in this
context, except by *always* exluding them (which you don't want).

You have two options.

You can replace the _autocd function with this:

    _autocd() { [[ -o autocd ]] && _cd || _command_names }

Or you can use a group-order style:

    zstyle ':completion:*:-command-::' group-order \*-directories

which will cause all the directory names to appear first in the menu,
even though any commands that match will also appear.
