微软的Visual Studio代码编辑器非常不错,但它对构建c++项目没有默认支持。

我如何配置它来做到这一点?


当前回答

有一个更简单的方法来编译和运行c++代码,不需要配置:

安装代码运行器扩展 在文本编辑器中打开您的c++代码文件,使用快捷键Ctrl+Alt+N,或者按F1,然后选择/键入运行代码,或者右键单击文本编辑器,然后在上下文菜单中单击运行代码,代码将被编译并运行,输出将显示在输出窗口中。

此外,您可以在设置中更新配置。如果你想使用不同的c++编译器,c++的默认配置如下:

"code-runner.executorMap": {
    "cpp": "g++ $fullFileName && ./a.out"
}

微软现在有一个C/ c++语言扩展。你可以通过“快速打开”(Ctrl+p)来安装它,然后输入:

ext install cpptools

截至2016年5月,这是非常基本的。

构建任务是特定于项目的。要创建一个新项目,请在Visual Studio Code中打开一个目录。

按照这里的说明,按Ctrl + Shift + P,输入Configure Tasks,选择它并按Enter。

的任务。Json文件将被打开。将以下构建脚本粘贴到文件中,并保存:

{
    "version": "0.1.0",
    "command": "make",
    "isShellCommand": true,
    "tasks": [
        {
            "taskName": "Makefile",

            // Make this the default build command.
            "isBuildCommand": true,

            // Show the output window only if unrecognized errors occur.
            "showOutput": "always",

            // Pass 'all' as the build target
            "args": ["all"],

            // Use the standard less compilation problem matcher.
            "problemMatcher": {
                "owner": "cpp",
                "fileLocation": ["relative", "${workspaceRoot}"],
                "pattern": {
                    "regexp": "^(.*):(\\d+):(\\d+):\\s+(warning|error):\\s+(.*)$",
                    "file": 1,
                    "line": 2,
                    "column": 3,
                    "severity": 4,
                    "message": 5
                }
            }
        }
    ]
}

现在转到菜单文件→首选项→键盘快捷键,为构建任务添加以下键绑定:

// Place your key bindings in this file to overwrite the defaults
[
    { "key": "f8",          "command": "workbench.action.tasks.build" }
]

现在,当您按下F8时,Makefile将被执行,错误将在编辑器中下划线显示。

要在VS代码中构建/运行c++项目,您需要手动配置任务。Json文件,在工作空间文件夹的。vscode文件夹中。 打开任务。json,按ctrl + shift + P,并键入Configure tasks,并按enter,它将带你到tasks.json

在这里,我提供我的任务。json文件,并添加了一些注释,使文件更容易理解,可以作为配置任务的参考。Json,希望对大家有用

tasks.json

{
    "version": "2.0.0",
   
    "tasks": [
        
        {
            "label": "build & run",     //It's name of the task , you can have several tasks 
            "type": "shell",    //type can be either 'shell' or 'process' , more details will be given below
            "command": "g++",   
            "args": [
                "-g",   //gnu debugging flag , only necessary if you want to perform debugging on file  
                "${file}",  //${file} gives full path of the file
                "-o",   
                "${workspaceFolder}\\build\\${fileBasenameNoExtension}",    //output file name
                "&&",   //to join building and running of the file
                "${workspaceFolder}\\build\\${fileBasenameNoExtension}"
            ],
            "group": {
                "kind": "build",    //defines to which group the task belongs
                "isDefault": true
            },
            "presentation": {   //Explained in detail below
                "echo": false,
                "reveal": "always",
                "focus": true,
                "panel": "shared",
                "clear": false,
                "showReuseMessage": false
            },
            "problemMatcher": "$gcc"
        },
        
    ]
}

现在,直接从VS code任务文档中声明

type属性说明:

type:任务类型。对于自定义任务,这可以是shell或process。如果指定了shell,则对命令进行解释 作为shell命令(例如:bash、cmd或PowerShell)。如果 如果指定了进程,则该命令将被解释为进程到 执行。

控件可以控制终端的行为 任务中的表示属性。json。它提供以下属性:

reveal: Controls whether the Integrated Terminal panel is brought to front. Valid values are: - always - The panel is always brought to front. This is the default - never - The user must explicitly bring the terminal panel to the front using the View > Terminal command (Ctrl+`). - silent - The terminal panel is brought to front only if the output is not scanned for errors and warnings. focus: Controls whether the terminal is taking input focus or not. Default is false. echo: Controls whether the executed command is echoed in the terminal. Default is true. showReuseMessage: Controls whether to show the "Terminal will be reused by tasks, press any key to close it" message. panel: Controls whether the terminal instance is shared between task runs. Possible values are: - shared: The terminal is shared and the output of other task runs are added to the same terminal. - dedicated: The terminal is dedicated to a specific task. If that task is executed again, the terminal is reused. However, the output of a different task is presented in a different terminal. - new: Every execution of that task is using a new clean terminal. clear: Controls whether the terminal is cleared before this task is run. Default is false.

    ]
