# 使用vscode与服务端R交互

vscode 一款让人爱不释手的IDE，也是前端工程师一大杀器。在window上使用R对数据进行操作，当数据量太大的时候，电脑就会吃不消；而服务端的R一看起来就灰常的枯燥。加上最近vscode增加了对R语言的支持，使得在vscode中编写R脚本变成现实，vscode多session的特点使得能够同时打开多个窗口使用服务端的R进行大数据的计算。

服务端R使用常见3种方法

* 1.`Rstudio-server`建立网页版的Rstudio，需要管理员权限
* 2.使用conda安装Rstudio，再使用x-manger将信号转发，软件收费
* 3.使用vscode与连接服务器，直接与服务端进行交互

我使用的是第3种方法

## 1.vscode安装插件

使用`Remote-SSH`插件连接服务器

* 点击魔方图标，搜索关键字`remote-ssh`
* 下载对应的插件即可

## 2.使用`Remote-SSH`连接·服务器

### 2.1如下所示进行信息的配置

### 2.2配置信息如下

* 如果存在墙的话，可以使用x-shell隧道将信号转发到本地

  参考 <https://zpliu.gitbook.io/booknote/mysql/02sqlyog-ruan-jian-pei-zhi> 进行隧道转发

## 3.验证密码

* 密码输入后就登录成功了

![输入密码](https://43423.oss-cn-beijing.aliyuncs.com/img/20200322221756.png)

* 选择要显示的目录，这里需要再一次输入密码

  ***这里选择\*\*\*\*`.vscode`\*\*\*\*目录是方便vscode根据文件的变化情况进行自动刷新***

* 登录成功后的样子

## 4.给服务器装vscode的插件

* `R`
* `R LSP Client`

![服务端插件](https://43423.oss-cn-beijing.aliyuncs.com/img/20200322221903.png)

### 4.1分别对插件`R`和`R LSP Clint`进行配置

* 主要就是将**服务器端的R执行脚本绝对路径**添加进去

![插件配置信息](https://43423.oss-cn-beijing.aliyuncs.com/img/20200322221921.png)

* `R LSP Client`插件也是同样的进行配置

## 5.重启vscode

* 再次输出服务器密码进行登录
* 在目录下创建一个新的`test.R`文件

![脚本编写](https://43423.oss-cn-beijing.aliyuncs.com/img/20200322221943.png)

* 在`test.R`文件中编写脚本

  ```r
  install.packages("ggplot2")
  require(ggplot2)
  qplot(carat, price, data = diamonds, xlab = "hhh", xlim = c(1, 5))
  ```
* 快捷键`ctrl + enter`按行执行脚本
* `ctrl + shift +s`执行整个文件

### 5.1最终效果

* vscode能够自动跟踪文件的变化，刷新图片进行显示

## 云端部署vscode

由于没有管理员权限，就只能以非管理员的形式进行安装了

### 1.在云服务器中安装`code-serve`

```bash
## 下载最新版本的压缩包 https://github.com/cdr/code-server/releases/tag/v3.9.2

wget -c https://github.com/cdr/code-server/releases/download/v3.9.2/code-server-3.9.2-linux-amd64.tar.gz
##运行code-serve
cd   code-server-3.9.2-linux-amd64/bin
./code-server
```

### 2.配置code-serve

> 参考 <https://github.com/cdr/code-server/blob/main/docs/guide.md>

设置登录密码

```bash
##配置文件 ~/.config/code-server/config.yaml
 # Replaces "auth: password" with "auth: none" in the code-server config.
sed -i.bak 's/auth: password/auth: none/' ~/.config/code-server/config.yaml
```

### 3.安装插件

有的插件可能不是开源的，在vscode 上可以安装而在conde-serve上不行，但是code-server上有自己的开源插件marketplace，通过GitHub来构建Vs code上的代码

因此如何安装code-serve上缺失的一些插件呢？

* 对于插件`HTML Snippets`而言

```bash
## 下载github上的源代码
wget -c https://github.com/abusaidm/html-snippets/archive/refs/heads/master.zip
## 解压到code-serer extension目录即可
unzip master.zip
```

遇到vscode不能识别python编译器的问题，好像是python插件版本的问题

> 参考 <https://github.com/microsoft/vscode-python/issues/14959#issuecomment-778113519>

### 配置代码补齐工具`Kite`,不适用于centos
