I think there's something do with pkg_* in the latest zsh ports, but I
could be mistaken.  Hmm, it seems to be in zsh-devel, but not zsh.  Take
a look anyway.

I made this for manpages, but it's _really_ ugly and slow.  It also
doesn't work sometimes, but I don't care enough to have bothered fixing
it.  It's better than nothing anyway.

function find_manpage() {
        start=$1
        choices=""
        count=0

        # need a colon in IFS to split $MANPATH
        old_IFS="$IFS"
        IFS=":$IFS"

        # need this to prevent error from "no match found"
        setopt nullglob

        for i in ${=MANPATH}; do
                for j in $i/*/${start}*; do
                        # strip off leading path and trailing .n.gz
                        choices="$choices ${${j##*/}%%.?.gz}"
                        let "count = count + 1"
                        if [[ $count -ge 100 ]]; then
                                break 2
                        fi
                done
        done

        # turn off again
        unsetopt nullglob

        # put IFS back to what it was before
        IFS="$old_IFS"
        unset old_IFS

        # set the reply array
        eval reply=($choices)

        # clean up variables
        unset choices start count
}

compctl -K find_manpage man
