Question

我正在基于VSCode设置一个可从USB驱动器运行的便携式环境。我已经在根目录（D :)上安装了MinGW和VScode，并创建了一个包含C ++ env的文件夹。组态。编辑：该功能适用于Windows。

因此，我知道为了编译和运行.cc文件，我必须运行Build Task或Task（我只了解基本概念）。我尝试构建应该执行此操作的.json任务，但没有得到任何结果。

我想了解基础知识，因此可以为其他环境创建自己的（简单的）.json任务。

这是我到目前为止尝试过的：

{
"version": "2.0.0",
"tasks": [
    {
        "type": "shell",
        "label": "Compile&Run",
        "command":["D:\\mingw-w64\\x86_64-8.1.0-win32-seh-rt_v6-rev0\\mingw64\\bin\\g++.exe"],
        "args": [
            "-g",
            "${file}",
            "-o",                                    // I think that this is the problem
            "${fileBasenameNoExtension}.out", ",", "./${fileBasenameNoExtension}.out"
        ],

        //I do not fully understand what this next lines mean or do, they came by defaul.
        "options": {
            "cwd": "D:\\mingw-w64\\x86_64-8.1.0-win32-seh-rt_v6-rev0\\mingw64\\bin"
        },
        "problemMatcher": [
            "$gcc"
        ],
        "group": {
            "kind": "build",
            "isDefault": true
        }
    }
]

}

这是我在Linux系统中拥有的task.json，我通过搜索模板来获取它并设法使其正常工作。它正是我需要的。创建并运行一个.out文件。

{
    "version": "2.0.0",
    "tasks": [
        {
            "label": "debug",
            "type": "shell",
            "command": "",
            "args": ["g++","-g", "${relativeFile}", "-o","a.exe"]
        },
        {
            "label": "Compile and run",
            "type": "shell",
            "command": "",
            "args": [
                "g++","-g", "${relativeFile}", "-o","${fileBasenameNoExtension}.out", "&&", "clear" , "&&" , "./${fileBasenameNoExtension}.out"
            ],
            "group": {
                "kind": "build",
                "isDefault": true  
            },
            "problemMatcher": {
                "owner": "cpp",
                "fileLocation": ["relative", "${workspaceRoot}"],
                "pattern": {
                    "regexp": "^(.*):(\\d+):(\\d+):\\s+(warning|error):\\s+(.*)$",
                    "file": 1,
                    "line": 2,
                    "column": 3,
                    "severity": 4,
                    "message": 5
                }
            }
        },

    ]
}

Answer 1

tasks.json不是您要用于运行/调试可执行文件的文件。为此，您想使用launch.json。您可以创建一个依赖于构建任务的启动任务。

由于您非常需要模板，因此我将为您提供反向工程师的职位。由于这不是一个完整的答案，可能会被否决。但这是我可以帮助您的唯一方法。

{
    {
    "version": "2.0.0",
    "tasks": [
        {
            "label": "Build & run",
            "type": "shell",
            "command": "path/to/bin/g++ main.cpp -o main.exe && main",
            "problemMatcher":"$gcc",
            "presentation": {
                "echo": false,
                "reveal": "always",
                "focus": false,
                "panel": "shared",
                "showReuseMessage": false,
                "clear": true
            },
            "group": {
                "kind": "build",
                "isDefault": true
            }
        }
    ]
}

Answer 3

const confirmEnding = (str, target) => str.substr(-target.length) === target ? 
                                                                      true : 
                                                                      false;

这很好用

Answer 4

如果有人正在寻找一种在调试前（按 F5）在 VSCode 中自动构建 cpp 文件的方法，一个简单的解决方案是在 launch.json 文件中添加 "preLaunchTask": "${defaultBuildTask}",。

这里是我在 linux 中使用 g++ 的文件（你可以删除 smfl 库）

tasks.json

{
    "version": "2.0.0",
    "tasks": [
        {
            "type": "cppbuild",
            "label": "C/C++: g++ build active file",
            "command": "/usr/bin/g++",
            "args": [
                "-g",
                "${workspaceFolder}/src/*.cpp",
                "-o",
                "${workspaceFolder}/bin/outputfile",
                "-lsfml-audio",
                "-lsfml-graphics",
                "-lsfml-network",
                "-lsfml-system",
                "-lsfml-window"
            ],
            "options": {
                "cwd": "${workspaceFolder}"
            },
            "problemMatcher": [
                "$gcc"
            ],
            "group": {
                "kind": "build",
                "isDefault": true
            },
            "detail": "compiler: /usr/bin/g++"
        }
    ]
}

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) Launch",
            "type": "cppdbg",
            "request": "launch",
            "program": "${workspaceFolder}/bin/outputfile",
            "args": [],
            "stopAtEntry": false,
            "cwd": "${workspaceFolder}",
            "environment": [],
            "externalConsole": false,
            "MIMode": "gdb",
            "preLaunchTask": "${defaultBuildTask}",
            "setupCommands": [
                {
                    "description": "Enable pretty-printing for gdb",
                    "text": "-enable-pretty-printing",
                    "ignoreFailures": true
                }
            ]
        }
    ]
