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

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

你可以在这里阅读:

截至2016年5月,这是非常基本的。

你可以在Visual Studio Code的2.0.0版本任务中引用这个最新的要点,https://gist.github.com/akanshgulati/56b4d469523ec0acd9f6f59918a9e454

您可以轻松地编译和运行每个文件,而无需更新任务。它是通用的,并且还为输入项打开终端。

这里的基本问题是构建和链接c++程序在很大程度上依赖于所使用的构建系统。你将需要支持以下不同的任务,使用一些插件和自定义代码的组合:

General C++ language support for the editor. This is usually done using ms-vscode.cpptools, which most people expect to also handle a lot of other stuff, like build support. Let me save you some time: it doesn't. However, you will probably want it anyway. Build, clean, and rebuild tasks. This is where your choice of build system becomes a huge deal. You will find plugins for things like CMake and Autoconf (god help you), but if you're using something like Meson and Ninja, you are going to have to write some helper scripts, and configure a custom "tasks.json" file to handle these. Microsoft has totally changed everything about that file over the last few versions, right down to what it is supposed to be called and the places (yes, placeS) it can go, to say nothing of completely changing the format. Worse, they've SORT OF kept backward compatibility, to be sure to use the "version" key to specify which variant you want. See details here:

https://code.visualstudio.com/docs/editor/tasks

...但注意冲突:

https://code.visualstudio.com/docs/languages/cpp

警告:在下面所有的答案中,任何以“version”标签低于2.0.0开头的内容都是过时的。

这是我目前能找到的最接近的东西。请注意,我把大部分繁重的工作都交给了脚本,这并没有给我提供任何我可以接受的菜单项,如果不在这里显式地添加另外三个条目,就没有任何好的方法来选择调试和发布。综上所述,以下是我可以容忍的.vscode/任务。Json文件:

            }
        }
    ]
}

Note that, in theory, this file is supposed to work if you put it in the workspace root, so that you aren't stuck checking files in hidden directories (.vscode) into your revision control system. I have yet to see that actually work; test it, but if it fails, put it in .vscode. Either way, the IDE will bitch if it isn't there anyway. (Yes, at the moment, this means I have been forced to check .vscode into subversion, which I'm not happy about.) Note that my build scripts (not shown) simply create (or recreate) a DEBUG directory using, in my case, meson, and build inside it (using, in my case, ninja).

运行、调试、附加、停止。这些是另一组任务,定义在“launch.json”中。至少以前是这样。微软把文档搞得一团糟,我甚至都不确定了。

一个新的2.0.0任务的makefile任务示例。json版本。

在下面的代码片段中,我希望它们会有用。

{
    "version": "2.0.0",
    "tasks": [
        {
            "label": "<TASK_NAME>",
            "type": "shell",
            "command": "make",
            // use options.cwd property if the Makefile is not in the project root ${workspaceRoot} dir
            "options": {
                "cwd": "${workspaceRoot}/<DIR_WITH_MAKEFILE>"
            },
            // start the build without prompting for task selection, use "group": "build" otherwise
            "group": {
                "kind": "build",
                "isDefault": true
            },
            "presentation": {
                "echo": true,
                "reveal": "always",
                "focus": false,
                "panel": "shared"
            },
            // arg passing example: in this case is executed make QUIET=0
            "args": ["QUIET=0"],
            // Use the standard less compilation problem matcher.
            "problemMatcher": {
                "owner": "cpp",
                "fileLocation": ["absolute"],
                "pattern": {
                    "regexp": "^(.*):(\\d+):(\\d+):\\s+(warning|error):\\s+(.*)$",
                    "file": 1,
                    "line": 2,
                    "column": 3,
                    "severity": 4,
                    "message": 5
                }
            }
        }
    ]
}

下面是我如何使用g++编译器配置我的VS for c++,它工作得很好,包括调试选项:

任务。json文件

{
    "version": "0.1.0",
    "command": "g++",
    "isShellCommand": true,
    // compiles and links with debugger information
    "args": ["-g", "-o", "hello.exe", "hello.cpp"],
    // without debugger information
    // "args": ["-o", "hello.exe", "hello.cpp"],
    "showOutput": "always"
}

发射。json文件

{
    "version": "0.2.0",
    "configurations": [
        {
            "name": "C++ Launch (Windows)",
            "type": "cppdbg",
            "request": "launch",
            "program": "${workspaceRoot}/hello.exe",
            "MIMode": "gdb",
            "miDebuggerPath": "C:\\MinGw\\bin\\gdb.exe",
            "stopAtEntry": false,
            "cwd": "${workspaceRoot}",
            "externalConsole": false,
            "visualizerFile": "${workspaceRoot}/my.natvis"
        }
    ]
}

我还在VS Code中安装了“C/ c++ for Visual Studio Code”扩展

如果你的项目有一个CMake配置,那么设置VSCode就很简单了,比如设置任务。Json如下:

{
    "version": "0.1.0",
    "command": "sh",
    "isShellCommand": true,
    "args": ["-c"],
    "showOutput": "always",
    "suppressTaskName": true,
    "options": {
        "cwd": "${workspaceRoot}/build"
    },
    "tasks": [
        {
            "taskName": "cmake",
            "args": ["cmake ."]
        },
        {
            "taskName": "make",
            "args" : ["make"],
            "isBuildCommand": true,
            "problemMatcher": {
                "owner": "cpp",
                "fileLocation": "absolute",
                "pattern": {
                    "regexp": "^(.*):(\\d+):(\\d+):\\s+(warning|error):\\s+(.*)$",
                    "file": 1,
                    "line": 2,
                    "column": 3,
                    "severity": 4,
                    "message": 5
                }
            }
        }
    ]
}

这假设在工作区的根目录中构建了一个带有CMake配置的文件夹。

还有一个CMake集成扩展,它在VScode中添加了一个“CMake build”命令。

PS !问题matcher是为clang-builds设置的。要使用GCC,我相信你需要将fileLocation更改为relative,但我还没有测试过这个。
