Doing a git clone of a tag in Go - the easy way

main.go

package main

import (
	"log"

	"gopkg.in/src-d/go-git.v4/plumbing"

	"gopkg.in/src-d/go-git.v4"
)

// Basic example of how to clone a repository using clone options.
func main() {
	url := "https://github.com/arehmandev/pochelm.git"
	directory := "pochelm"
	tag := "v0.2.0"

	gitclonetag(url, directory, tag)
}

func gitclonetag(repourl, directory, tag string) {

	y := plumbing.ReferenceName(tag)

	// Clone the given repository to the given directory, you can also clone branches via ReferenceName: "refs/heads/branchname"
	_, err := git.PlainClone(directory, false, &git.CloneOptions{
		URL:               repourl,
		ReferenceName:     "refs/tags/" + y,
		SingleBranch:      true,
		RecurseSubmodules: git.DefaultSubmoduleRecursionDepth,
	})
	if err != nil {
		log.Fatal(err)
	}
