问题 All, I have been working with vim for some time now, and love everything about it - there is only one thing I really miss from IDEs like RubyMine, and that is advanced autocompletion. For reference, here is my standard VIM setup: https://github.com/wrwright/.vim I have tried ctags with omnicomplete + supertab, and the one major element I miss is the ability to bring up a context sensitive list of attributes/constants/methods. For example, as I learn RubyMotion, I'd love to have some help
