NeoVim

hyperextensible Vim-based text editor. 基于 vim 的超扩展的文本编辑器. 搭配各种扩展的话, 甚至可以做个IDE. 最后附一份SpaceVIM的配置(尝试了下, 个人用得不舒服).

treesitter.lua配置文件

require 'nvim-treesitter.configs'.setup {
  ensure_installed = "maintained", -- one of "all", "maintained" (parsers with maintainers), or a list of languages
  highlight = {
    enable = true,              -- false will disable the whole extension
  },
}

配置完成之后, 进入nvim, 运行:PlugInstall进行插件的安装.
