zsh: port completion is no longer available (+mp_completion)

[jrblevin@…]

I upgraded my ports today and noticed that my tab completion was broken for the port command in zsh. While investigating this, I noticed that the zsh-devel port was marked obsolete in favor of the zsh port. I'm glad to see that the zsh port was brought up to date, but is it possible to restore the +mp_completion variant?

The patch should be straightforward. The mp_completion code from zsh-devel simply copied the _port file to the appropriate directory:

variant mp_completion description {Install port(1) completion file} {
    post-destroot {
        set sitedir ${prefix}/share/${my_name}/site-functions
        xinstall -m 0644 ${filespath}/_port \
            ${destroot}${sitedir}
    }
}

The _port file is, of course, still available in the repository:

browser:trunk/dports/shells/zsh-devel/files/_port?rev=100755

I verified that placing this file in /opt/local/share/zsh/site-functions restored my ability to use tab completion with the port command using the current zsh package.

The mp_completion variant was removed in r101584. The reason given in the commit message is that it "installs a file that has zero versioning relationship to anything else that is installed".

I will not be restoring mp_completion, but I’m planning on putting the function file into contrib and creating a subport for it. Eventually, I might even get the zsh devs to include it with zsh itself. In the meantime, a more robust solution for you would be to put _port into a directory you control (i.e., not one under the MacPorts prefix) and add that directory to your fpath.

I’ll leave this ticket open until I add the new subport.

Thanks very much for your quick reply. I'll keep an eye out for the subport, and I'll place the file elsewhere in the meantime.

Why a subport? It doesn't seem like the code for installing mp_completion would have anything in common with the code for building zsh.

[larryv (Lawrence Velázquez)]

I was thinking that it would be more convenient, but you’re probably right; it should be a separate port.

What about crafting a port for zsh-completions on github? It has a completion file for MacPorts.

The port completion file was added as part of the zsh-completions package in r114630. If you need port completions, please install that package.

You should probably mention something about that in the description...
