ubuntu下用visual studio code调试C++

尽管VS Code本质上是一个编辑器，但是对插件的友好支持使得它可以成为很好用的IDE（用完以后果断抛弃了CLion、QTcreator、Kdevelop等一系列IDE），从此只用一个VS CODE。
用VS CODE可以很方便地对C++程序进行debug，以linux Ubuntu环境为例：
Ctrl+Shift+D调出debug界面，然后点左上角的设置按钮，选择C/C++，出现launch.json文件。

    "version": "0.2.0",
    "configurations": [
        {
            "name": "(gdb) Launch",
            "type": "cppdbg",
            "request": "launch",
            "program": "enter program name, for example ${workspaceFolder}/a.out",
            "args": [],
            "stopAtEntry": false,
            "cwd": "${workspaceFolder}",
            "environment": [],
            "externalConsole": true,
            "MIMode": "gdb",
            "setupCommands": [
                {
                    "description": "Enable pretty-printing for gdb",
                    "text": "-enable-pretty-printing",
                    "ignoreFailures": true
                }
            ]
        }
    ]
}

只用对program和args两项设置即可，如设置成：

            "program": "${workspaceFolder}/build/drivable",
            "args": ["build/file.pcd"],

相当于在终端下：

${workspaceFolder}
./build/drivable build/file.pcd

设置好后按F5即可调试，加断点等和其他IDE一样
