利用vscode當golang編寫IDE的配置過程

vscode以良好的兼容性進來收到追捧。整個vscode執行效率比基於java的ide效率又高。一直用liteide來編寫golang,但是liteide調試時斷點不能實時增刪，每次增刪斷點，重新運行調試纔有用，而且變量窗口觀察 變量又不方便。於是乎開始琢磨用vscode。偶然看到一個大神發佈的一個vscode包含了golang環境。擴展的名字是：VSCode Essentials

立馬安裝這個擴展，寫了golang helloworld. OK，一切正常。
但是，一般golang工程，不可能就一個main.go，vscode如何管理golang工程又不得而知，原來用liteide可以編譯調試的工程，放到vscode就不行。後來仔細梳理了一下。終於實現了 vscode全面編譯原來的liteide的golang工程。
一下幾點要注意：
1，golang工程的目錄結構最好要遵守，我的目錄結構如下圖：

2，創建一個工作區文件 aaa.code-workspace，如上圖，放在根目錄，內容如下：

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

3,創建一個launch.json文件（調試菜單，打開配置，就是它），內容如下：

{
    // 使用 IntelliSense 瞭解相關屬性。 
    // 懸停以查看現有屬性的描述。src\Pic98\main.go
    // 欲瞭解更多信息，請訪問: https://go.microsoft.com/fwlink/?linkid=830387
    "version": "0.2.0",
    "configurations": [
        {
            "name": "Launch",
            "type": "go",
            "request": "launch",
            "mode": "auto",
            "program": "${workspaceRoot}/src/Pic98/main.go", // 每次調試啓動的文件
            "env": {
                "GOPATH":"C:/Users/Administrator/go;${workspaceRoot}", //可以指定gopath
                "GOROOT":"C:/go",

            },
            "args": []
        }
    ]
}

然後把系統環境變量administraor的path的關於go的目錄刪除，只留默認的。path變量必須包含goroot/bin;gopath/bin。
最後就是GOPATH/bin（我的是C:\Users\Administrator\go\bin）目錄下面，最少要有如下11個文件：

    目錄: C:\Users\Administrator\go\bin


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

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

如果沒有就要用go get 安裝；比如安裝 dlv.exe

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

大功告成，變量，監視，堆棧，斷點，log輸出，應有盡有！爽上天了。
