高效使用Vscode（C++&Python）

1.关于vscode

下载地址： https://code.visualstudio.com/download (linux / win)
建议：拥有一个微软账号或者github账号登录vscode来保存和更新自己的

2.vscode常用插件安装

3.关于SSH

什么是SSH
一种安全的网络协议

两种连接方式

• a. 终端连接
• b. vscode连接（上文提到的remote插件必须装好）

Vscode 如何进行ssh连接

• Host:主机名可以自己随便定义一个名字

文件传输(关于scp)
下载:

从当前服务器，向ip为ry2.ggpu.net，用户名为root，端口号为16101的服务器传送数据到/data/yws目录下

scp -r -P 16101   /data/yws/code root@ry2.ggpu.net:/data/yws
1

上传:

4.高效的快捷键和自定义设置

4.1 快捷键

其他参考： https://betterprogramming.pub/15-useful-vscode-shortcuts-to-boost-your-productivity-415de3cb1910

4.2 设置alias

可以通过alias的方式，用更加简单的字符串去代表比较长的字符串。可以通过
vim ~/.bashrc 在配置文件中 添加alias简化的命令。

alias ll= 'ls -alF'
alias la= 'ls -A'
alias l= 'ls -CF'
alias cdme= 'cd /datav/'
alias cs= 'clear'
alias sfm= 'du --block-size=MiB --max-depth=1 | sort -rn'
alias sfg= 'du --block-size=GiB --max-depth=1 | sort -rn'
alias bb = 'vim ~/.bashrc'
alias ss = 'source ~/.bashrc'

也可以不打开~/.bashrc直接在终端通过echo的方式写入命令，例如:
echo alias ss= \"ls -A\" >> ~/.bashrc
然后快捷指令生效, source ~/.bashrc

5.高效调试配置(tasks.json 和 launch.json)

需要配置：c_cpp_properties.json,launch.json,settings.json,tasks.json,这四个配置文件；

5.1 配置launch.json

创建launch.json

lanuch.json文件的脚本

• lanuch.json配置了python debug和c++ debug,实现python 和c++ 进行混编。

Python 和 c++

{
	"version":"0.2.0",
	"configurations": [
	// python debug
	{
		"name":"Python file",
		"type":"python",
		"request":"launch",
		"program":"${file}", // 当前文件
		//"program":"src/main.py",  // 如果指定当前目录具体的文件，介意这样写
		"program":"src/main.py",
		"console": "integratedTerminal",
		"justMyCode":true  //设置false的话，你可以进入一些库的源码里面进行调试，比如说进入pytorch的一部分源码		
	},
	
	// c++ debug
	{
	 	"name": "C++ file",
	 	"type": "cppdbg",
	 	"request":"launch",
	 	"program": "${workspaceFolder}/workspace/pro", // 这里的pro指的是你要调试的文件，这里指的是cpp最终生成的可执行文件
	 	"args": [],
	 	"environment":[{"name":"LD_LIBRAYRY_PATH","value":"$(LD_LIBRAYRY_PATH):/mypath/to/lib/"}], //相当于直接  export LD_LIBRAYRY_PATH=$LD_LIBRAYRY_PATH:/mypath/to/lib
		"stopAtEntry":false,
		"cwd":"${workspaceFolder}/workspace",  //c++ 运行过程时会在这寻找依赖和其他文件（比如 图片）
		 "externalConsole": false,
            "MIMode": "gdb",
            "miDebuggerPath": "/usr/bin/gdb",
            "environment": [
                {
                    "name": "LD_LIBRARY_PATH", 
                    "value": "/home/yuanwushui/anaconda3/lib/python3.9/site-packages/trtpy/trt8cuda112cudnn8/lib64:/home/yuanwushui/anaconda3/lib:/home/yuanwushui/anaconda3/lib/python3.9/site-packages/trtpy/trt8cuda112cudnn8/py39:/home/yuanwushui/anaconda3/lib/python3.9/site-packages/trtpy/cpp-packages/opencv4.2/lib:/home/yuanwushui/anaconda3/lib/python3.9/site-packages/trtpy/lib:$LD_LIBRARY_PATH"
                }
            ],
            "setupCommands": [
                {
                    "text": "-enable-pretty-printing",
                    "ignoreFailures": true
                }
            ],
		"preLaunchTask":"build"   //在运行launch之前先运行task.json里面的东西，因为task.json中的label是"build"
	}
	
 ]

5.2 配置tasks.json

创建tasks.json

• 按 F1
• 选择“任务：配置任务
  
• 按 Enter 键，vscode 将为您创建一个示例 task.json
  
  tasks.json文件的脚本

"version":"2.0.0",
"task":[
	{
		"label":"build",
		"type": "shell",
		"command":"make pro -j6"	// 这里的pro指的是你要调试的文件，这里指的是cpp最终生成的可执行文件
	}
]

每次运行launch之前都会运行tasks （这里指的是都会编译一遍）

5.3配置settings.json

创建settings.json
参见: 怎么快速打开vscode settings.json文件

settings.json文件的脚本

• 在.vscode/settings.json中配置"*.cu":"cuda-cpp"可以实现cuda的语法解析

settings.json

{
    "files.associations": {
        "*.cpp": "cpp",
        "*.cu": "cuda-cpp",

5.4 配置c_cpp_properties.json

• 让 intelliSense engine（语法提示，自动补全）能够找到所需要的头文件

c_cpp_properties.json

{
    "configurations": [
        {
            "name": "Linux",
            "includePath": [
                "${workspaceFolder}/**",
                "/home/yuanwushui/anaconda3/lib/python3.9/site-packages/trtpy/trt8cuda112cudnn8/include/**",
                "/home/yuanwushui/anaconda3/lib/python3.9/site-packages/trtpy/cpp-packages/opencv4.2/include/**"
            ],
            "compilerPath": "/usr/bin/gcc",
            "cStandard": "gnu11",
            "cppStandard": "gnu++11",
            "intelliSenseMode": "linux-gcc-x64"
        }
    ],
    "version": 4

5.4 C++ Python 联合调试

在launch中配置好python 和c++的debug配置如下

那我们如何确定我们按f5的时候是debug python 还是c++呢？

可以通过上图红色箭头这个来选择debug的是Python file 还是C++ file，其中Python file 和C++ file 是在launch.json中定义的name变量的值。

同时在调试的窗格中也要选择调试的是python,还是C++：
