VSCode基础

Settings

• VSCode配置文件分为两种（其中项目会重复）

  • User Settings：用户对所有项目的配置
  • Workspace Settings：针对当前项目的设置

• 配置方式分为两种完全相同

  • UI：提示丰富
  • JSON：配置快捷，JSON字典格式

Command Palette

Python

• 选择默认python环境

Terminal

• 选择默认terminal，可能的terminal包括cmd、powershell、 WSL（若启用Linux子系统）

Original Setting

Terminal

{
	"terminal.integrated.shell.windows"："/path/to/shell",
		// 默认shell
	"terminal.integrated.shellArgs.windows": [ ],
	"terminal.integrated.shellArgs.linux": [ ],
	"terminal.integrated.shellArgs.osx": [ ],
		// VSCode创建terminal启动参数（3系统分别配置）
}

• VSCode terminal分为很integrated、external

• VSCode应该是兼容所有terminal shell，如

  • C:/Windows/System32/cmd.exe
  • C:/Windows/System32/powershell.exe
  • C:/Windows/System32/wsl.exe：WSL启用
  • “/path/to/git/bin/bash.exe”：Git中bash等

• VSCode terminal虽然兼容多种shell，但只能创建默认shell

  • 需要多种shell只能切换默认shell再创建
  • python shell等shell是特殊shell，无法默认创建，必须要 在命令面板中创建（虽然在普通shell中打开python环境， 但是VSCode不认可）

Python

{
	"python.condaPath": "/path/to/conda/Scripts",
		// conda安装目录Scripts文件夹
	"python.venvPath": "/path/to/conda/envs",
		// 虚拟环境目录，VSCode会在其中查找虚拟环境，作为
		// Command Palette中的备选项
	"python.pythonPath": "/path/to/python.exe",
		// 默认python解释器路径
	"python.terminal.activateEnvironment": true,
		// 创建python shell时，尝试中激活虚拟环境
}

• python.terminal.activateEnviroment激活的虚拟环境由 python.pythonPath决定

  • VSCode会尝试执行python.pythonPath同级中 Scripts/activate.bat激活虚拟环境

  • 因此虚拟环境需要安装conda，否则没有 Scripts/ativate.bat无法正常激活默认虚拟环境

CPPC

配置文件

• .vscode/c_cpp_properties.json

  {
  	"configurations": [
  		{
  			"name": "WSL",
  			"includePath": [
  				"${workspaceFolder}/**"
  			],
  			"defines": [
  				"LOCAL",
  				"_DEBUG",
  				"UNICODE",
  				"_UNICODE"
  			],
  			"compilerPath": "/usr/bin/gcc",
  			"cStandard": "c11",
  			"cppStandard": "c++14",
  			"intelliSenseMode": "gcc-x64"
  		}
  	],
  	"version": 4
  }

  • C/C++项目基本配置

• .vscode/tasks.json：利用VSCode的Tasks功能调用WSL的 GCC/G++编译器

  {
  	// tasks.json
  	// See https://go.microsoft.com/fwlink/?LinkId=733558
  	// for the documentation about the tasks.json format
  
  	"version": "2.0.0",
  	"tasks": [
  		{
  			"label": "Build",
  			"command": "g++",
  			"args": [
  				"-g",
  				"-Wall",
  				"-std=c++14",
  				"/mnt/c/Users/xyy15926/Code/cppc/${fileBasename}",
  				"-o",
  				"/mnt/c/Users/xyy15926/Code/cppc/a.out",
  				"-D",
  				"LOCAL"
  			],
  			"problemMatcher": {
  				"owner": "cpp",
  				"fileLocation": [
  					"relative",
  					"${workspaceRoot}"
  				],
  				"pattern": {
  					"regexp": "^(.*):(\\d+):(\\d+):\\s+(warining|error):\\s+(.*)$",
  					"file": 1,
  					"line": 2,
  					"column": 3,
  					"severity": 4,
  					"message": 5
  				}
  			},
  			"type": "shell",
  			"group": {
  				"kind": "build",
  				"isDefault": true
  			},
  			"presentation": {
  				"echo": true,
  				"reveal": "silent",
  				"focus": true,
  				"panel": "shared"
  			}
  		},
  		{
  			"label": "Run",
  			"command": "/mnt/c/Users/xyy15926/Code/cppc/a.out",
  			"type": "shell",
  			"dependsOn": "Build",
  			"group": {
  				"kind": "test",
  				"isDefault": true
  			},
  			"presentation":{
  				"echo": true,
  				"reveal": "always",
  				"focus": true,
  				"panel": "shared",
  				"showReuseMessage": true
  			}
  		}
  	]
  }

  • 这里为方便将运行程序任务同> Task: Run Test Task 任务关联，可以在命令面板执行此指令

• .vscode/launch.json：gdb调试配置

  {
  	// launch.json
  	// Use IntelliSense to learn about possible attributes.
  	// Hover to view descriptions of existing attributes.
  	// For more information, visit: https://go.microsoft.com/fwlink/?linkid=830387
  	"version": "0.2.0",
  	"configurations": [
  		{
  			"name": "(gdb) Bash on Windows Launch",
  			"type": "cppdbg",
  			"request": "launch",
  			"program": "/mnt/c/Users/xyy15926/Code/cppc/a.out",
  			"args": ["-f", "Threading"],
  			"stopAtEntry": false,

  				"debuggerPath": "/usr/bin/gdb",
  				"pipeProgram": "C:\\windows\\system32\\bash.exe",
  				"pipeArgs": ["-c"],
  				"pipeCwd": ""
  			},
  			"setupCommands": [
  				{
  					"description": "Enable pretty-printing for gdb",
  					"text": "-enable-pretty-printing",
  					"ignoreFailures": false
  				}
  			],
  			"sourceFileMap": {
  				"/mnt/c": "c:\\",
  				"/mnt/d": "d:\\"
  			},
  			"preLaunchTask": "Build"
  		},
  	]
  }

Git

{
	"git.ignore.MissingGitWarning": true,
	"git.path": "/path/to/xxxgit.exe"
}

• “git.path”既可以是windows下Git，也可以是“伪装”Git，使用 工具wslgit，让VSCode 直接使用WSL内的Git

KeyMapper

• <c-s-\>`：新建默认terminal绘画
• <c-s-p>：command palette
