Vscode中使用Romote远程开发调试Ros2环境

首先，成功安装ros2环境，参考官方文档中的教程，能用运行出来此处的代码

Writing a simple publisher and subscriber (Python) --- ROS 2 Documentation: Iron documentation

下载vscode，进行远程开发，具体参考：Vscode进行远程开发-CSDN博客

在vscode中安装调试ros2所需要的插件，有Python、Pylance、C/C++、CMake Tools、ROS

这些插件安装完成之后，我们已经可以在Vscode中自由跳转Python代码和Ros环境中的rclpy包了

之所以能跳转ros环境的包，是因为我们项目文件夹下面的./vscode中settings.json中成功导入了ros环境的位置

除了.settings.json文件夹，安装Ros插件后，.vscode文件中会自动有一个c_cpp_properties.json文件，里面也是已经自动填充了内容

接下来在.vscode中创建tasks.json文件

会自动生成tasks.json文件，并且插入内容

然后继续在.vscode创建一个文件launch.json文件

      "type": "python",
      "request": "launch",
      "program": "/opt/demo_ws/src/py_pubsub/py_pubsub/publisher_member_function.py", #注意此处改成你自己的要调试的文件路径
      "console": "integratedTerminal",
    },
    // Example gdb launch of a ros executable
    {
      "name": "(gdb) Launch",
      "type": "cppdbg",
      "request": "launch",
      "program": "/opt/demo_ws/py_pubsub/lib/py_pubsub/talker",#此处暂时不太清楚
      "args": [],
      "stopAtEntry": true,
      "cwd": "/opt/demo_ws",
      "externalConsole": false,
      "MIMode": "gdb",
      "setupCommands": [
        {
          "description": "Enable pretty-printing for gdb",
          "text": "-enable-pretty-printing",
          "ignoreFailures": true
        }
      ]
    }
  ],
  "inputs": [
    {
      "id": "package",
      "type": "promptString",
      "description": "Package name",
      "default": "learning_ros2"
    },
    {
      "id": "program",
      "type": "promptString",
      "description": "Program name",
      "default": "ros2_talker"
    }
  ]
}

我们目前只能调试python文件，无法调试 ros executable 。打上断点，即可调试了

还有一个问题是：

没有办法调试srv和msg，目前需要解决一下
