带有ruby的vim omnicomplete仅部分有效

Question

我有一个vim 7.2的+ruby版本(也尝试了7.3和自定义编译版本)，但我只在某些情况下使用omnicomplete (ctrl-x ctrl-o)。

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，它不会自动补全任何attr_关键字。

我试过了，我所有的插件都禁用了，所有的插件都启用了。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 )。我还在C++、JavaScript和大约1/2打的其他语言上使用VIM，所以其中一些语言也有完整的东西：

那么，有没有一种方法可以让我在omnicomplete中获得对Ruby的完全支持，如果是这样的话？或者，这是omnicomplete为Ruby提供的最多的功能吗？

Answer 1

Vim自动完成应该是开箱即用的，我不知道有什么方法.nil，所以我不确定这是不是一个真正的问题。

然而，对于没有完成attr_reader之类的所有功能，setlocal omnifunc=syntaxcomplete#Complete会修复它，但是它应该放在ftplugin/ruby/my_custom_ruby_ftplugin.vim中，而不仅仅是你的vimrc中，或者如果你喜欢，你可以把setl命令放在你的vimrc中的autocmd FileType ruby setl omnifunc=syntaxcompelete#Complete中，然后它应该会像你期望的那样工作。
