GO language study notes one

Learning go through algorithms

First go locale install

Enter goLang official websitehttps://golang.google.cn/dl/

I downloaded the go1.15.15.windows-amd64.msi version

After downloading, start the installation, it will automatically configure the environment variables, and then run cmd to see if the go version command is executed to see if the installation is successful.After installing go, install vscode and download it from the official website.

Then create a new goPath folder, and then create three folders under this folder, src, pkg and bin respectively. This folder is the go execution path, then edit the environment variable, create a new GOPATH in the system environment variable and put the goPathThe path is placed in it, and the ; interval is used to create a new go execution directory later.Then put %GOPATH% in Path.

Then configure the vscode setting.json (the location is in File->Preferences->Settings->The icon in the upper right corner opens the settings)

{"go.buildOnSave": "workspace","go.lintOnSave": "package","go.vetOnSave": "package","go.buildTags": "","go.buildFlags": [],"go.lintFlags": [],"go.vetFlags": [],"go.coverOnSave": false,"go.useCodeSnippetsOnFunctionSuggest": false,"go.formatOnSave": true,"go.formatTool": "goreturns","go.goroot": "D:\\Go","go.gopath": "D:\\GoPath","go.gocodeAutoBuild": false,"workbench.iconTheme": "vscode-icons","gopls": {"experimentalWorkspaceModule": true} },"go.toolsManagement.autoUpdate": true,"window.zoomLevel": -1,"terminal.integrated.sendKeybindingsToShell": true}

Here, change go.goroot to your own go installation location, and go.gopath to the go execution file location.

Install the god extension in vscode after configuration

After installation, create a new go file, vscode will prompt you to install some plugins, click all install.

The installation may not be successful here, if the installation fails, you need to enter cmd to execute

go env -w GO111MODULE=on

go env -w GOPROXY=https://proxy.golang.com.cn,direct

Then execute go env to see if the change is successful, then go back and execute all install , if it still fails, you need to install manually

1. In the %GOPATH%\src\ directory, create the path golang.org\x
2. Go to %GOPATH%\src\golang.org\x, download the source code of the required tools git clone https://github.com/golang/tools.git tools
3. After the clone is completed, a tools folder will be generated, so that the source code required by the tool is ready
4. Go to %GOPATH% and execute

5.  go install github.com/ramya-rao-a/go-outlinego install github.com/acroca/go-symbolsgo install golang.org/x/tools/cmd/gurugo install golang.org/x/tools/cmd/gorenamego install github.com/rogpeppe/godefgo install github.com/sqs/goreturnsgo install github.com/cweill/gotests/gotests

6. Process golint separately, the source code of golint is located at https://github.com/golang/lint, after entering %GOPATH%\src\golang.org\xExecute git clone https://github.com/golang/lintdownload the source code required by golint
7. Go to %GOPATH% and execute go install github.com/golang/lint/golint

At this point, you are basically done, it is possible that the installation of gopls will fail

Also enter %GOPATH% and execute go install golang.org/x/tools/cmd/gopls

Then create a new main folder in src and then execute hold down shift and right-click to enter PowerShell to execute the go mod init main command, and then execute go build

At this point, the go locale is set up.

Finally, if you want vscode to run normally, you also need to configure lang.json (run -> add configuration) to configure it according to your own server and needs

{"name": "Launch","type": "go","request": "launch","mode": "debug","program": "${fileDirname}","env": { //environment variables"GOPATH":"D:/goPath","GOOS":"windows" //To be compiled into win},"args": [],"showLog": true,"configurations": [ ]}
