Subject: zsh completion for ri

Hi,

ZnZ and I wrote _ri, a zsh completion function for ri. We think it is very useful.
It also works well. But we are not certain about how to use zsh bullt-in functions.
Are there any zsh expert who can brush up this code?

How to install:

1. put _ri file into /usr/share/zsh/functions/Completion/Unix.
2. add the next line to ~/.zshrc

 zstyle ':completion:*' use-cache true

----- from here ------
#compdef ri
 
_arguments -C -s \
  '(-h --help)'{-h,--help}'[print help message]' \
  '(-c --classes)'{-c,--classes}'[Display the names of classes and modules we know about]' \
  '-d+[A directory to search for documentation]:directory:_files -/' \
  '(-f --format)'{-f,--format}'[Format to use when displaying output]:format:(ansi bs html plain simple)' \
  '(-l --list-names)'{-l,--list-names}'[List all the names known to RDoc, one per line]' \
  '(-T --no-pager)'{-T,--no-pager}'[Send output directly to stdout]' \
  '(-w --width)'{-w+,--width+}'[output width]' \
  '(-v --version)'{-v,--version}'[Display the version of ri]' \
  "*:names:->ri_names" \
  && return 0
 
if [[ $state = ri_names ]]; then
  if ( [[ ${+_ri_list_names} -eq 0 ]] || _cache_invalid ri-names ) &&
    ! _retrieve_cache ri-names; then
    _ri_list_names=( $(_call_program ri--list-names ri -l 2>/dev/null) )
    _store_cache ri-names _ri_list_names
  fi
  _wanted ri_names expl 'ri --list-names' compadd "$@" -a _ri_list_names
fi
