ruby-on-rails – vim omnicomplete与ruby仅部分有效

2023年3月2日 224次阅读

我有一个
ruby版本的vim 7.2(也尝试过7.3和自定义编译版本),但我只是在某些情况下使用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

omn​​icomplete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.

我已经尝试了所有我的插件已禁用,再次启用所有插件.我也尝试过使用vim-ruby插件.我安装的插件是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).我还使用VIM for C,JavaScript以及大约其他几十种其他语言,因此其中一些语言还有一些完整的内容：

        let Tlist_Ctags_Cmd='/usr/bin/ctags'

    endif

那么,有没有办法可以在omnicomplete中完全支持Ruby,如果有的话怎么样？或者,这是omnicomplete为Ruby提供的最多吗？

最佳答案 Vim自动完成应该开箱即用,我不知道任何方法.nil所以我不确定这是否是一个真正的问题.

但是关于没有完成attr_reader和类似的omnicompletion,setlocal omnifunc = syntaxcomplete#Complete修复它,但是它应该放在ftplugin / ruby​​ / my_custom_ruby_ftplugin.vim而不是仅仅在你的vimrc中,或者如果你喜欢你可以将该setl命令放入autocmd FileType ruby​​ setl omnifunc = syntaxcompelete#在你的vimrc中完成,它应该像你期望的那样工作.
