Subject: Re: a dream: gem require auto-installer

Perhaps this one will be less blamed :

  def my_require(gem,pack=nil)
    require gem
  rescue LoadError => e
    print "'#{gem}' package is missing. Can I load #{pack||'it'} \
    from internet without slap or go to hell ? (y/n) : "
    exit! if STDIN.gets.chomp !~ /^y|o$/i
    system("gem install  #{pack||gem} --no-ri --no-rdoc")  ;
    Gem.clear_paths() && require(gem) && puts("loading '#{gem}' ok!")
  end

  my_require 'xxx'
  my_require 'json','json_pure'
  my_require 'green_shoes' ,   'gtk2,green_shoes'
  my_require 'foo' , 'zzz'


Thank you very much for your help,
realy...
