VSCode 必须安装以下插件:

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。

All tools successfully installed. You're ready to Go :).

修改默认配置的方法:

在 Preferences -> Setting 然后输入 go,然后选择 setting.json,填入你想要修改的配置

  • 自动完成未导入的包。
1
  "go.autocompleteUnimportedPackages": true,
  • VSCode 的一些插件需要配置代理,才能够正常安装。
1
  "http.proxy": "192.168.0.100:1087",
  • 如果你遇到使用标准包可以出现代码提示,但是使用自己的包或者第三方库无法出现代码提示,你可以查看一下你的配置项。
1
  "go.inferGopath": true,
  • 如果引用的包使用了 ( . “aa.com/text”) 那这个text包下的函数也无法跳转进去,这是为什么?

修改 "go.docsTool" 为 gogetdoc,默认是 godoc

1
  "go.docsTool": "gogetdoc",

其他

  1. 当我们在使用 import 功能的时候,如果无法通过 lint 检查,则不会执行自动 import。
  2. 如果你需要自动 import 的前提是你必须把要导入的包的函数写完整。

附带我的 settings.json

{
  "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",
}

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

打开 setting.json

{
    "go.gopath": "D:\\Go",    
    "go.goroot": "D:\\GoPath",  
    "go.inferGopath": true,
    "go.autocompleteUnimportedPackages": true,
    "go.gocodePackageLookupMode": "go",
    "go.gotoSymbol.includeImports": true,
    "go.useCodeSnippetsOnFunctionSuggest": true,
    "go.useCodeSnippetsOnFunctionSuggestWithoutType": true,
    "go.docsTool": "gogetdoc",
    "go.formatTool": "goimports",
    "go.useLanguageServer": true
}
