1.卸载原有的vim

sudo yum remove vim
2.使用Git下载vim8源码
git clone git@github.com:vim/vim.git
Git的简单配置可以参考CentOS7-Git配置

3.安装依赖文件

sudo yum install -y python-devel python3-devel ruby ruby-devel lua lua-devel perl per-devel perl-ExtUtils-Embed libX11-devel ncurses-devel

4.编译安装vim8

./configure --with-features=huge \
            --enable-multibyte \
            --enable-python3interp=yes \
            --with-python3-config-dir=/usr/local/python/lib/python3.9/config-3.9-aarch64-linux-gnu \
            --enable-gui=gtk2 \
            --enable-pythoninterp \
            --enable-cscope \
            --prefix=/usr/local/vim

make
make install
添加环境变量
export PATH=$PATH:/usr/local/vim/bin

5.创建软链接
sudo ln -s /usr/local/vim/bin/vim /usr/bin/vim
创建成功后，可以方便的使用vim命令打开vim编辑器

配置选项说明

--with-features=huge:支持最大特性
--enable-pythoninterp:支持python2编写的插件
--enable-python3interp:支持python3编写的插件
--enable-rubyinterp:支持ruby编写的插件
--enable-luainterp:支持lua编写的插件
--enable-perlinterp:支持perl编写的插件
--with-python-config-dir=/usr/lib64/python2.7/config/:指定python2的位置，不同的机器位置不同，确保指定的文件夹中包含config.c文件
--with-python3-config-dir=/usr/local/python3.6/lib/python3.6/config-3.6m-x86_64-linux-gnu/:同上，也要确保有config.c文件
关于python3的安装可以参考CentOS7-Python3安装
--enable-cscope:打开cscope支持
--enable-multibyte:支持多字节，可以输入中文
--prefix=/usr/local/vim:指定vim的安装位置

安装centos7最小化系统，再安装VIM插件coc.nvim出现
Error: javascript bundle not found, please compile code ~ | of coc.nvim by esbuild.
或者出现：
please compile coc.nvim by: npm run build

不管怎样就是安装不上，查资料也不管，最后重新装系统都不行，有的说是升级git，升级后再安装确实管用，但也不一定是这个问题。记录一下git升级

CentOS7上的Git版本太陈旧，在使用过程中会遇到问题，因此需要升级git版本。

git --version

git version 1.8.3.1
　　系统版本：（CentOS 7.6）

安装依赖
　　源代码安装和编译git，需安装一些依赖。

yum install curl-devel expat-devel gettext-devel openssl-devel zlib-devel asciidoc
yum install gcc perl-ExtUtils-MakeMaker

卸载旧版本
yum remove git

编译安装Git
　　Git软件包可在此获取：https://mirrors.edge.kernel.org/pub/software/scm/git/。

　　我们选择最新版的：

git-2.23.0.tar.xz 16-Aug-2019 20:17 5M

安装步骤
复制代码

cd /usr/local/
wget https://mirrors.edge.kernel.org/pub/software/scm/git/git-2.23.0.tar.xz
tar -xvf git-2.23.0.tar.xz
mv git-2.23.0 git
cd git
./configure  --prefix=/usr/local
make && make install
echo "export PATH=$PATH:/usr/local/git/bin" >> /etc/profile
source /etc/profile

验证版本
[root@localhost ~]# git --version
git version 2.23.0

非root用户使用
如果是非root用户使用git，则需要配置下该用户下的环境变量。

$ echo "export PATH=$PATH:/usr/local/git/bin" >> ~/.bashrc
$ source ~/.bashrc

vim安装自动补全插件coc.nvim
一、vim必须8.0以上
二、安装node.js
curl -sL install-node.now.sh/lts | bash
三、安装plug或vundle插件，以下内容加入插件中

Plug 'neoclide/coc.nvim', {'branch': 'master', 'do': 'yarn install --frozen-lockfile'}
或
Plugin 'neoclide/coc.nvim', {'branch': 'master', 'do': 'yarn install --frozen-lockfile'}

然后在vim运行：

:PlugInstall

如果coc.vim下载不了，可以进入插件目录git下载到本地在运行PlugInstall
接着运行

:CocInstall coc-json coc-tsserver

四、把以下内容加入.vimrc ，原文地址：https://github.com/neoclide/coc.nvim

" Set internal encoding of vim, not needed on neovim, since coc.nvim using some
" unicode characters in the file autoload/float.vim

五、进入vim输入CocConfig进入配置文件，然后输入

CocInstall coc-pyright

对于Python3自动补全，其他语言参照：https://github.com/neoclide/coc.nvim/wiki/Install-coc.nvim
六、成功后如果弹出警告框在.vimrc加入以下内容

let g:coc_disable_startup_warning = 1

VIM模式省略，基本命令带过...
插入：i、a、o；I、A、O
保存、退出：q、wq、!q、w、!q、wq=x
移动：h、j、k、l #h一次移动几行
w: 移至下一个单词的词首 #w 一次移动几个单词
e: 跳至当前或下一个单词的词尾
b: 跳至当前或前一个单词的词首
0: 绝对行首
^: 行首的第一个非空白字符
$: 绝对行尾

G：跳转至第#行；

G：最后一行
p：粘贴下
P：粘贴上
y：复制
u:撤销 最多30次 #u 撤销N次
r：替换单个
R：替换多个
.：重复前一次编辑
末行模式下，直接给出行号即可
Ctrl+f: 向下翻一屏
Ctrl+b: 向上翻一屏
Ctrl+d: 向下翻半屏
Ctrl+u: 向上翻半屏
x: 删除光标所在处的单个字符

x: 删除光标所在处及向后的共#个字符

d命令跟跳转命令组合使用

dw, #de, #db

dd: 删除当前光标所在行

dd: 删除包括当前光标所在行在内的#行

末行模式下：
StartADD,EndADDd
.: 表示当前行
$: 最后一行
+#: 向下的#行

:.,+5d  #删除当前后和后5行
:.,$d  删除当前行到最后一行
:2,5d  删除2到5行

Ctrl+r：撤消最近一次撤消操作
可视化模式：
v: 按字符选取
V：按矩形选取
查找
/PATTERN ?PATTERN n，N翻页
在末行模式下使用s命令
s/PATTERN/string/g g全部 i不区分大小写
ADDR1,ADDR2s#PATTERN#string#gi 开始和结束中间内容查找替换

使用vim编辑多个文件
vim FILE1 FILE2 FILE3
:next 切换至下一个文件
:prev 切换至前一个文件
:last 切换至最后一个文件
:first 切换至第一个文件
退出
:qa 全部退出

分屏显示一个文件
Ctrl+w, s: 水平拆分窗口
Ctrl+w, v: 垂直拆分窗口

在窗口间切换光标：
Ctrl+w, ARROW
:qa 关闭所有窗口

分窗口编辑多个文件
vim -o : 水平分割显示
vim -O : 垂直分割显示

将当前文件中部分内容另存为另外一个文件
末行模式下使用w命令
:w
:ADDR1,ADDR2w /path/to/somewhere # 1,10w /root/abc.txt 把当前文件1-10行写入abc.txt 如果有内容就覆盖

将另外一个文件的内容填充在当前文件中
:r /path/to/somefile # :r /etc/issue 把issue内容填充到当前文件光标下方

跟shell交互
:! COMMAND

vim 将文件所有行合并到一行
在 Normal Mode下执行:
ggvGJ
[
gg 用于跳到行首
v 转换成 visual 模式
G 跳到最后一行
J 合并行
