如何在Visual Studio代码中使用Delve调试器 [英] How to use Delve debugger in Visual Studio Code

问题描述

我已经为VS代码安装了Go扩展，但无法使其正常工作。

dlv debug可以从终端正常工作。

  dlv debug src / github.com / user / hello 
  

$ b

launch.json ：

  {
版本：0.2.0，
配置：[
 {
name：Launch，
type：go，
request：launch，
mode：debug，
program：$ {workspaceRoot}，
env：{}，
args：[] 
} 
] 
} 
  

你知道如何设置它吗？

解决方案

使用Golang在Visual Studio代码中进行调试，请执行以下步骤：

 （注意：对于Windows操作系统，将所有$ GOPATH替换为％GOPATH ％）
  

• 安装最新版
  
  

  I have installed the Go extension for VS Code, but unable to make it work.

  "dlv debug" works alright from the terminal.

  dlv debug src/github.com/user/hello
  

  The launch.json:

  {
      "version": "0.2.0",
      "configurations": [
          {
              "name": "Launch",
              "type": "go",
              "request": "launch",
              "mode": "debug",
              "program": "${workspaceRoot}",
              "env": {},
              "args": []
          }
      ]
  }
  

  Do you know how to set it up?

  解决方案

  For using Delve debugger in Visual Studio Code with Golang, do the following steps:

  ( Note: for Windows OS replace all $GOPATH with %GOPATH% )
  

  • Install Latest Golang and set GOROOT and GOPATH
  • Add $GOPATH/bin to your OS PATH environment variable.
  • set environment variable: GO15VENDOREXPERIMENT = 1
  • run: go get github.com/derekparker/delve/cmd/dlv and make sure dlv binary generated in your $GOPATH/bin
  • Install Visual Studio Code
  • Launch VS Code Quick Open (Ctrl+P), paste this command: ext install Go , and press enter.
  • click install Rich Go language support for Visual Studio Code
  • click Enable and restart Visual Studio Code
  • Inside Visual Studio Code Open Folder Ctrl+Shift+E , e.g.: $GOPATH\src\hello\
  • Then Open hello.go from that folder (or make new file Ctrl+N and save it on this folder):

  package main
  
  import "fmt"
  
  func main() {
      fmt.Println("Hello World!")
      i := 101
      fmt.Println(i)
  }
  

  • Then Open Debugger Ctrl+Shift+D
  • on this line: i := 101 press F9 to set or toggle beakpoint.
  • Press F5 to start debugging or to Run the application, if asked to select environment: select Go.
  • Press F10 to Step Over.
  • Press F11 to Step Into.
  • Press Shift+F11 to Step Out.
  • Press Shift+F5 to Stop Debugging.
  • Press Ctrl+Shift+F5 to Restart Debugging.

  My launch.json untouched:

  {
      "version": "0.2.0",
      "configurations": [
          {
              "name": "Launch",
              "type": "go",
              "request": "launch",
              "mode": "debug",
              "remotePath": "",
              "port": 2345,
              "host": "127.0.0.1",
              "program": "${workspaceRoot}",
              "env": {},
              "args": [],
              "showLog": true
          }
      ]
  }
