Visual Studio Code同时debug多种代码的方式

今天看了一下，猜应该是configurations里面多写一个就行，试了下，真的可以同时debug Python和Go代码。

可以打断点、单步执行Python和Go代码。

launch.json 如下

{
    // Use IntelliSense to learn about possible attributes.
    // Hover to view descriptions of existing attributes.
    // For more information, visit: https://go.microsoft.com/fwlink/?linkid=
    "version": "0.2.0",
    "configurations": [

        {
            "name": "Python: 当前文件",
            "type": "python",
            "request": "launch",
            "program": "${file}",
            "console": "integratedTerminal"
        },
        {
            "name": "Go: 当前文件",
            "type": "go",
            "request": "launch",
            "program": "${file}",
            "mode": "auto"

        }
    ]
}

然后在DEBUG后面选择用哪一个配置跑就行了。

只是还有两点觉得做得不太好的地方，

一是 watch里面不会显示nil值，而是显示类型。

二是 不知道是否因为加了watch，两个变量都会在未初始化的时候报错，感觉像IDE的bug。
