Is there a way to optimize my listing?

listing.bash

        npm list --global --parseable 2> /dev/null \
            | grep '/generator-' \
            | while read line; do __yo_getSuggestion $line; done \
            | sort -u \
            | uniq

suggestion.zsh

__yo_getSuggestion() {
    modulePath="${1:-DEBUG_ME}"

    pkg="$(basename "$modulePath")"
    (( $+blacklist[(r)$pkg] )) && continue # skip blacklisted items
    package="${pkg//$k}"
    versions=( "$package"/ ) # limit to directories
    description="$(__yo_getDescription "$modulePath")"
    suggestion=$(printf "%s:%s" "$package" "$description")
    # echo "$suggestion"

    generator+=( "$suggestion" )
}
