vscode调试golang环境搭建及配置

准备vscode

在官网下载最新版的vscode:

安装golang插件

• 打开扩展面板

  vscode->查看->扩展

• 找到go插件 在搜索框里输入go, 找到第二行写有 rich go language support for visual studio code的插件, 点击安装

  注意不是排名最高的

• 重启编辑器

配置启动项

• 打开调试面板

  vscode->查看->调试

• 添加调试目标

  在"没有调试"的下拉框中点击"添加配置.."

• 添加目标调试配置

  例子:

  {
      "version": "0.2.0",
      "configurations": [
          {
              "name": "launch",
              "type": "go",
              "request": "launch",
              "mode": "debug",
              "remotepath": "",
              "port": 2345,
              "host": "127.0.0.1",
              "program": "${filedirname}",
              "env": {
                  "gopath":"d:/develop/vscodegolang"
              },
              "args": [],
              "showlog": true
          }
      ]
  }
  

其中: "port", "host"都是go插件自动生成的

"env"为设置环境变量, 设置为你的工程目录就可以(包含bin, src的文件夹)

准备调试插件

此时找到main.go按f5, 会报错提示:

failded to continue:"cannot find delve debugger. install from https://github.com/derekparker/delve & ensure it is in your "gopath/bin" or "path"

我们使用go命令行编译调试器

go get github.com/derekparker/delve/cmd/dlv

将dlv调试器放在gopath(工程目录)的bin目录下

开始调试

选中要调试的main.go, 点击f5, 既可以开始调试

调试快捷键和visual studio系一致

• f9 切换断点
• f10 step over
• f11 step in
• shift+f11 step out

注意点

• 某些结构体成员无法直接显示时, 可以直接选中变量名, 添加到监视, 或者右键点击: "调试:求值"

多项目调试

在launch.json中可以添加多组调试入口, 通过调试面板中选中对应的配置开启不同目标的调试

{
    "version": "0.2.0",
    "configurations": [
        {
            "name": "client",
            "type": "go",
            "request": "launch",
            "mode": "debug",
            "remotepath": "",
            "port": 2345,
            "host": "127.0.0.1",
            "program": "${filedirname}",
            "env": {
                "gopath":"d:/develop/vscodegolang"
            },
            "args": [],
            "showlog": true
        },

        {
            "name": "server",
            "type": "go",
            "request": "launch",
            "mode": "debug",
            "remotepath": "",
            "port": 2345,
            "host": "127.0.0.1",
            "program": "${workspaceroot}/src/server",
            "env": {
                "gopath":"d:/develop/vscodegolang"
            },
            "args": [],
            "showlog": true
        }
    ]
}

"program"中的"${filedirname}"是以当前选中文件作为启动点

更建议使用"program"的"${workspaceroot}", 以包名作为启动点的方式进行配置
