文件组织

.vscode folder#

Workspace specific files are in a .vscode folder at the root. For example, tasks.json for the Task Runner and launch.json for the debugger.

Launch.json attributes

Variable substitution

Platform-specific properties

In the example below, debugging the program always stops on entry except on macOS:

{
  "version": "0.2.0",
  "configurations": [
    {
      "type": "node",
      "request": "launch",
      "name": "Launch Program",
      "program": "${workspaceFolder}/node_modules/gulp/bin/gulpfile.js",
      "stopOnEntry": true,
      "osx": {
        "stopOnEntry": false
      }
    }
  ]
}

编译调试顺序

launch.json用来调试

task.json用来生成，相当于是任务的集合，可通过ctrl+shift+p，运行任务，比如：

{
	"version": "2.0.0",
	"tasks": [
		{
			"type": "cppbuild",
			"label": "g++ build active file",
			"command": "/usr/bin/g++",
			"args": [
				"-fdiagnostics-color=always",
				"-g",
				"${file}",
				"-o",
				"${fileDirname}/${fileBasenameNoExtension}"
			],
			"options": {
				"cwd": "${fileDirname}"
			},
			"problemMatcher": [
				"$gcc"
			],
			"group": "build",
			"detail": "编译器: /usr/bin/g++"
		}
	]
}

在这里插入图片描述

参考VS Code 运行C++程序以及TASKS.JSON和LAUNCH.JSON文件的基础配置

The task’s properties have the following semantic:

label: The task’s label used in the user interface.
type: The task’s type. For a custom task, this can either be shell or process. If shell is specified, the command is interpreted as a shell command (for example: bash, cmd, or PowerShell). If process is specified, the command is interpreted as a process to execute.
command: The actual command to execute.
windows: Any Windows specific properties. Will be used instead of the default properties when the command is executed on the Windows operating system.
group: Defines to which group the task belongs. In the example, it belongs to the test group. Tasks that belong to the test group can be executed by running Run Test Task from the Command Palette.
presentation: Defines how the task output is handled in the user interface. In this example, the Integrated Terminal showing the output is always revealed and a new terminal is created on every task run.
options: Override the defaults for cwd (current working directory), env (environment variables), or shell (default shell). Options can be set per task but also globally or per platform. Environment variables configured here can only be referenced from within your task script or process and will not be resolved if they are part of your args, command, or other task attributes.
runOptions: Defines when and how a task is run.
c_cpp_properties.json用来配置C++标准

VScode tasks.json和launch.json的设置

注意：

要保证launch.json中preLaunchTask的值与此文件中label的值相同

Tips

调试

如果应用程序在sudo环境下和普通用户环境下表现不一致并且当前调试需要管理员模式，在Ubuntu下一种可能的做法是：

设置配置文件（makefiletool自动生成，stopAtEntry需要自己加，敲“”后会出现提示）：

{
    "makefile.extensionOutputFolder": "./.vscode",
    "makefile.launchConfigurations": [
        {
            "cwd": "/home/qemu/bin/debug",
            "binaryPath": "/home/qemu/bin/debug/hello",
            "binaryArgs": [],
            "stopAtEntry": true,
        }
    ]
}
