Spectrum Chain Development--ide Breakpoint Debugging Introduction

Spectrum Chain Development--ide Breakpoint Debugging Introduction

作者：GirpZhang

Experimental environment

• Windows10

• Go1.9.2.windows-amd64

• Visual Studio Code

• Git 2.18.0

Need to complete the Visual Studio Code + Golang Development environment configuration

• Installing GO1.9.2.WINDOWS-AMD64

• Install Git

• Install Golang, configure Gopath

  本例中使用的 "GOPATH":"E:/GoPath";"GOROOT":"E:/Go"

• Install Visual Studio Code, install the Go plugin, and the introduction is Rich Go language support for Visual Studio code

• Debug Configuration:

  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.."To add a target Debug configuration:

{    "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":"E:/GoPath",                "GOROOT":"E:/Go"            },            "args": [],            "showLog": true        }    ]}

Download Spectrum Code

git clone git@github.com:SmartMeshFoundation/Spectrum.git

Commissioning Preparation

• Create a new multilevel directory under E:/GOPATH/SRC: \github.com\smartmeshfoundation\spectrum

• Copy the code from the downloaded spectrum.git to E:/gopath/src/github.com/smartmeshfoundation/spectrum

• Open Vscode, select File-open folder, open Spectrum folder

• Open Cmd->smc->main.go File

• F5 debugging, you will be prompted with the following error:

Failded to continue:"Cannot find Delve debugger. Install from https://github.com/derekparker/delve & ensure it is in your "GOPATH/bin" or "PATH"

• Then we use the Go command line to compile the debugger, put the DLV debugger in the Gopath bin directory

  • Use the cmd command line to enter the directory E:\GoPath\bin

  • To perform a command installation DLV

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

• Then you can debug normally, and place breakpoints on the spot where you need to do one step:
