[PATCH] completion for opensolaris IPS package manager

["\"xRaich[o]²x\"" <raichoo@googlemail.com>]

I started working on some scripts for opensolaris commands (zpool, zfs, 
beadm and more are in the works). Here is the first for package 
management. It's still pretty basic but supports the features that are 
used the most (or at least i use the most ^^)

#compdef pkg

cmds=(
        'install:install a package'
     'uninstall:uninstall a package'
     'verify:verify a package'
     'info:fetch package info'
     'contents:show package contents'
     'list:list installed packages'
     'search:search for a package'
     'refresh:refresh catalogues'
     'image-create:create new image'
     'image-update:update an image'
     'set-authority:set an authority'
     'unset-authority:unset an authority'
     'authority:list authorities'
     'rebuild-index:rebuild index'
)

_pkg () {
    ret=1
    SHIFTER=0
    if [[ $words[2] == "-R" ]]; then
        if (( CURRENT == 3 )); then
            _directories && ret=0
            return ret
        elif (( CURRENT >= 4 )); then
            SHIFTER=2
        fi
    fi

    if (( CURRENT-SHIFTER == 2 )); then
        _describe 'pkg command' cmds && ret=0
    else
        case ${words[$(( 2 + SHIFTER ))]} in
            install)
                compadd $(awk $'{print $3}' $(find /var/pkg/catalog 
-name catalog -type f) | sort -u) && ret=0
                ;;
            uninstall|verify)
                compadd $(/usr/bin/ls /var/pkg/state/installed | cut -d@ 
-f1) && ret=0
                ;;
            search|info|contents)
                if [[ $words[$(( 3 + SHIFTER ))] == "-r" ]]; then
                    compadd  $(awk $'{print $3}' $(find /var/pkg/catalog 
-name catalog -type f) | sort -u) && ret=0
                else
                    compadd  $(/usr/bin/ls /var/pkg/state/installed | 
cut -d@ -f1) && ret=0
                fi
                ;;
            refresh|unset-authority)
                compadd $(find /var/pkg/catalog/ -type d | sed 1d | cut 
-d/ -f5) && ret=0
        esac
    fi
    return ret
}
