Golang how to install lib with go mod command

Question

I searched some article, all they used this why:

$go mod init project_name

Then created main.go and coded these:

package main

import "github.com/gin-gonic/gin"

func main() {
 r := gin.Default()
 r.GET("/ping", func(c *gin.Context) {
     c.JSON(200, gin.H{
         "message": "pong",
     })
 })
 r.Run() // listen and serve on 0.0.0.0:8080 (for windows "localhost:8080")
}

then go run main.go

but in the fact, I can't remember the lib's full name like "github.com/gin-gonic/gin" , maybe I just remember gin .

So is there some way to install lib like python pip tool or go get like go mod install gin

PS:

because that I am using goland as my IDE, under the GOPATH, I can get the code tips, but under the go mod, I couldn't get it, Then I have started the question of this.

⛔️ No.

If you don't know full name of the package you cann't get it.

You can try to use IDE's tips ( GoLand as example IDE) to find a package without <domain>/<owner>/... , import full package name and use

go mod tidy

to modify go.mod file, but IDE will try to find package in you local cache.

Checkout https://blog.golang.org/using-go-modules

The go module name is unique, so normally starts with domain name (unless it is a build-in module).

So just copy your import string's and run go get you will get it. eg

go get github.com/gin-gonic/gin

To update a module, use -u :

go get -u github.com/gin-gonic/gin

I don't think so because some project have the same name, golang use project path system for your project. Usually yourhost/author/projectname, try googling your lib you try to remember with golang keyword eg gin golang. Most of the time you will find it.

No. That is not how Go works.
