我有 vim 7.2 的 +ruby 版本（也尝试使用 7.3 和自定义编译版本），但我只能让全功能（ctrl-x ctrl-o）在某些情况下工作。
例如，如果我有
class MegaGreeter
attr_accessor :names
def initialize(names = "world")
@names = names
if @names.nil?
puts "hello #{@names}.each"
end
end
end
omnicomplete 适用于.each，但不适用于.nil。此外，它不会自动完成任何attr_关键字。
我已经在禁用所有插件的情况下尝试过，再次启用所有插件。我也尝试过使用 vim-ruby 插件。我安装的插件有 AfterColors、CSApprox、surround、color_sample_pack、mimicpak、taglist。
我的 .vimrc 中有以下部分（如果需要，我可以发布整个 .vimrc）。我还将 VIM 用于 C++、JavaScript 和大约 1/2 打其他语言，因此其中一些语言也有全能的东西：

那么，有没有一种方法可以在omnicomplete 中获得对Ruby 的完全支持，如果可以的话怎么办？或者，这是omnicomplete 为Ruby 提供的最大功能吗？
