利用vscode当golang编写IDE的配置过程

vscode以良好的兼容性进来收到追捧。整个vscode执行效率比基于java的ide效率又高。一直用liteide来编写golang,但是liteide调试时断点不能实时增删，每次增删断点，重新运行调试才有用，而且变量窗口观察 变量又不方便。于是乎开始琢磨用vscode。偶然看到一个大神发布的一个vscode包含了golang环境。扩展的名字是：VSCode Essentials

立马安装这个扩展，写了golang helloworld. OK，一切正常。
但是，一般golang工程，不可能就一个main.go，vscode如何管理golang工程又不得而知，原来用liteide可以编译调试的工程，放到vscode就不行。后来仔细梳理了一下。终于实现了 vscode全面编译原来的liteide的golang工程。
一下几点要注意：
1，golang工程的目录结构最好要遵守，我的目录结构如下图：

2，创建一个工作区文件 aaa.code-workspace，如上图，放在根目录，内容如下：

{
    "folders": [
        {
            "path": "H:\\DEVTOOLS\\project\\git\\TntLive\\WebSocketServerGo\\Pic98"
        }
    ],
    "settings": {
        "go.inferGopath": true,
    }
}

3,创建一个launch.json文件（调试菜单，打开配置，就是它），内容如下：

{
    // 使用 IntelliSense 了解相关属性。 
    // 悬停以查看现有属性的描述。src\Pic98\main.go
    // 欲了解更多信息，请访问: https://go.microsoft.com/fwlink/?linkid=830387
    "version": "0.2.0",
    "configurations": [
        {
            "name": "Launch",
            "type": "go",
            "request": "launch",
            "mode": "auto",
            "program": "${workspaceRoot}/src/Pic98/main.go", // 每次调试启动的文件
            "env": {
                "GOPATH":"C:/Users/Administrator/go;${workspaceRoot}", //可以指定gopath
                "GOROOT":"C:/go",

            },
            "args": []
        }
    ]
}

然后把系统环境变量administraor的path的关于go的目录删除，只留默认的。path变量必须包含goroot/bin;gopath/bin。
最后就是GOPATH/bin（我的是C:\Users\Administrator\go\bin）目录下面，最少要有如下11个文件：

    目录: C:\Users\Administrator\go\bin


Mode                LastWriteTime         Length Name
----                -------------         ------ ----

-a----       2019-05-30      9:27        8999424 guru.exe

如果没有就要用go get 安装；比如安装 dlv.exe

go get -u github.com/go-delve/delve/cmd/dlv

大功告成，变量，监视，堆栈，断点，log输出，应有尽有！爽上天了。
