Neovim出现的原因

• neovim代码库不需要向后兼容,方便开发维护
• 解决vim插件编写困难,特别是异步操作
• 解决vim插件编写困难,不再要求插件开发者需要熟悉vimscript
• 默认配置适应现代开发需求
• 更容易增加新功能

优化点

• 重构vim代码库,使用统一编码风格
• 放弃对旧系统的支持
• 适应现代开发的默认配置
• 提供丰富的查看开发API,例如python,lua,javascript等
• 支持与外部程序的通信

安装

1.源代码安装

由于需要github支持,在国内不容易安装

#1.安装
make CMAKE_BUILD_TYPE=RelWithDebInfo CMAKE_EXTRA_FLAGS="-DCMAKE_INSTALL_PREFIX=$HOME/neovim"
make install
export PATH="$HOME/neovim/bin:$PATH"

#2.卸载
cmake --build build/ --target uninstall

2.管理包安装

安装的版本比较低

#1.安装neovim
sudo apt install -y neovim

3.下载安装包安装

推荐这种方式安装

#1.根据操作系统下载安装包
https://github.com/neovim/neovim/blob/master/INSTALL.md#install-from-download
#2.解压
tar -xf nvim-linux64.tar.gz
#3.移动到安装位置
sudo mv nvim-linux64 /opt/
#4.设置环境变量
sudo vim /etc/profile
	export PATH="/opt/nvim-linux64/bin/bin:$PATH"
#5.环境变量起作用
source /etc/profile

配置

#遵守XDG基本目录结构
~/.config/nvim/init.vim 对应于 ~/.vimrc
~/.config/nvim 对应于 ~/.vim/

#查看默认设置
:help nvim-defaults

运行

#1.运行neovim
nvim

#2.实现neovim对python3的支持
#启用功能不需要重新编译
python3 -m pip install neovim

健康检查

#1.健康检查
:checkhealth

#2.解决没有剪切板
sudo apt install xclip

#3.WERNING Missing "neovim" npm(or yarn,pnpm) package.
npm install -g neovim
