Mac Vscode C++环境

安装vscode

https://code.visualstudio.com/docs/cpp/config-clang-mac

brew install visual-studio-code

进入vscode下载C++插件

可以使用code . 打开vscode

写cpp代码，运行选择

生成的tasks.json文件修改如下

{
    "version": "2.0.0",
    "tasks": [
        {
            "type": "shell",
            "label": "C/C++: clang++ build active file",
            "command": "/usr/bin/clang++",
            "args": [
                "-std=c++17",
                "-stdlib=libc++",
                "-g",
                "${file}",
                "-o",
                "${fileDirname}/${fileBasenameNoExtension}"
            ],
            "options": {
                "cwd": "${workspaceFolder}"
            },
            "problemMatcher": [
                "$gcc"
            ],
            "group": "build",
            "detail": "Task generated by Debugger."
        },
        {
            "type": "cppbuild",
            "label": "C/C++: clang++ 生成活动文件",
            "command": "/usr/bin/clang++",
            "args": [
                "-std=c++17",
                "-stdlib=libc++", //非常重要，如果没有这行，将不能使用C++17新标准，也不能使用C++11标准
                "-fcolor-diagnostics",
                "-fansi-escape-codes",
                "-g",
                "${file}",
                "-o",
                "${fileDirname}/${fileBasenameNoExtension}"
            ],
            "options": {
                "cwd": "${fileDirname}"
            },
            "problemMatcher": [
                "$gcc"
            ],
            "group": {
                "kind": "build",
                "isDefault": true
            },
            "detail": "调试器生成的任务。"
        }
    ]
}

launch.json文件如下：

{
    // 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": "C/C++: clang++ build and debug active file",
        "type": "cppdbg",
        "request": "launch",
        "program": "${fileDirname}/${fileBasenameNoExtension}",
        "args": [],
        "stopAtEntry": true,
        "cwd": "${workspaceFolder}",
        "environment": [],
        "externalConsole": false,
        "MIMode": "lldb",
        "preLaunchTask": "C/C++: clang++ build active file"
      }
    ]
  }

shift+cmd+p 搜索edit configurations(UI) 找到c_cpp_properties.json 文件如下：

{
    "configurations": [
        {
            "name": "Mac",
            "includePath": [
                "${workspaceFolder}/**"
            ],
            "defines": [],
            "macFrameworkPath": [
                "/Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/System/Library/Frameworks"
            ],
            "compilerPath": "/usr/bin/clang",
            "cStandard": "c17",
            "cppStandard": "c++17",
            "intelliSenseMode": "macos-clang-arm64"
        }
    ],
    "version": 4
}

若想自定义代码风格颜色，cmd+,打开设置界面，搜索主题，找到 setting.json，打开后加上

 // 自定义的颜色
    "editor.tokenColorCustomizations": {


        "comments": "#97999d", // 注释
        "keywords": "#f063a9", // 关键字
        "variables": "#3fc2be", // 变量名 
        "strings": "#e52f66", // 字符串
        "functions": "#34bcd7", // 内置函数名
        "numbers": "#c0c06a", // 数字
        "types": "#34a0e7", //类定义颜色
    }

彻底删除vscode

sudo rm -rf $HOME/Library/Application\ Support/Code
sudo rm -rf $HOME/.vscode

之后删除vscode程序即可。

问题1: vscode无法编译 vector{} 初始化，也不能使用C++17新特性，因为tasks.json是使用cppbuild方式，在args参数中加入

“-std=c++17”,

“-stdlib=libc++”,

#include 
#include 
#include 
#include 
#include 

using namespace std;

tuple func()
{
    return std::tuple(1, 2.2);
}

int main()
{
    vector msg = {"Hello", "C++", "World", "from", "VS Code", "and the C++ extension!"};

    auto [i, d] = func(); // 是C++11的tie吗？更高级
    cout << i << endl;
    cout << d << endl;

    cout << endl;
}

vscode终端无法输入

方法一

1. 在tasks.json下增加

{
   "label": "Open Terminal",
   "type": "shell",
   "command": "osascript -e 'tell application \"Terminal\"\ndo script \"echo hello\"\nend tell'",
   "problemMatcher": []
 }

2. 点击菜单栏的terminal选项下的run task ，在跳出界面选择 open terminal

3. 修改“launch.json”文件中的"externalConsole"的值为“true”

   之后输入时会跳出终端进行输入。

​ 参考Mac VSCode安装

方法二

1. 在vscode中安装“codelldb”插件。安装完成后会提示你要下载一个什么平台文件（xx platform啥的），等待下载完成。

2. 到install from VSIX 选择下载好的codelldb-aarch64-darwin.vsix 文件（这个文件m1芯片的）

3. 修改launch.json文件为

   {
       "version": "0.2.0",
       "configurations": [
         {
           "name": "C/C++: clang++ build and debug active file",
           "type": "lldb",
           "request": "launch",
           "program": "${fileDirname}/${fileBasenameNoExtension}",
           "args": [],
           "cwd": "${workspaceFolder}",
           "preLaunchTask": "C/C++: clang++ build active file"
         }
       ]
   }
   

4. 一定要按fn+f5执行才能在内置终端输入。

​ 之后所有的输出内容均在终端显示了。

注意：

1. 想要使用调试控制台就需要将launch.json文件改为如下，并且将codeLLdb禁用；

2. 想要终端输入就只能使用codeLLdb，launch.json文件如上，并按fn+f5调试，所有输入输出均在终端，若想使用调试控制台，直接点击界面的三角按钮运行。
