为Neovim添加可选功能

Question

I am trying to get hlsearch to work with Neovim. Per the documentation,

'hlsearch' 'hls' 'nohlsearch' 'nohls' 'hlsearch' 'hls'        boolean (default on)
                    global
                    {not available when compiled without the
                    +extra_search feature}

hlsearch is only available when compiled with +extra_search .

 $ vim --version                                                                                                                                                                                                                                                     [11:56:16]

My version of neovim doesn't seem to be compiled with extra_search . Is that indeed the issue, and if so how can I fix it?

Answer 1

It looks like NeoVim has far less compilation options, so hlsearch should be enabled in all builds. That documentation hint about extra_search presumably comes from the original Vim help, and doesn't apply to NeoVim.

So, if you see that :hi Search in its intended yellow, it should work, at least after :set hlsearch
