VS Code中golang环境配置

1.VSCode 建议安装以下插件：

首先你必须安装 Golang 插件，然后再给 Go 安装工具包。

在 VS Code 中，使用快捷键：command+shift+P，然后键入：go:install/update tools，将所有 16 个插件都勾选上，然后点击 OK 即开始安装。

Installing 16 tools at /Users/maiyang/develop/goworkspace//bin
  gocode
  gopkgs
  go-outline
  go-symbols
  guru
  gorename
  dlv
  godef
  godoc
  goreturns
  golint
  gotests
  gomodifytags
  impl
  fillstruct
  goplay

2.自动化配置：例如 代码自动补全 ，自动引依赖包等

File->Preferences -> Setting ，然后输入 go，然后选择 setting.json，填入你想要修改的配置。或者通过右上角图标

​，进入设置 setting.json页面，添加如下字段信息。实现代码自动补全需要设置字段为go.useCodeSnippetsOnFunctionSuggest ，go.inferGopath。

"go.autocompleteUnimportedPackages": true,         //自动完成未导入的包
“go.useCodeSnippetsOnFunctionSuggest”: true,       //自动提示代码，代码自动补全   
"go.docsTool": "gogetdoc",                         //支持跳转到文件名含.路径等功能
"go.inferGopath": true,                            //开启推断gopath的功能
"go.gocodePackageLookupMode": "go",                //代码包查询模式
"go.gotoSymbol.includeImports": true

可参考setting.json文件格式。

{
  "go.goroot": "",
  "go.gopath": "",
  "go.inferGopath": true,
  "go.autocompleteUnimportedPackages": true,
  "go.gocodePackageLookupMode": "go",
  "go.gotoSymbol.includeImports": true,
  "go.useCodeSnippetsOnFunctionSuggest": true,
  "go.useCodeSnippetsOnFunctionSuggestWithoutType": true,
  "go.docsTool": "gogetdoc",
}
