how to pull?

[Gluoo]

I want to pull the latest files from git repo, but I don't know how to do this, can anybody tell me? thanks.

I can clone a repo:
rep, cloneErr := git.PlainClone(LOCAL_CLONE_PATH, false, &git.CloneOptions{
URL: GIT_REP_URL,
Progress: os.Stdout,
})

but did not find any API of pull request, just find a fetch API, but not work well

repo, openErr := git.PlainOpen(LOCAL_CLONE_PATH)
pullError := repo.Fetch(&git.FetchOptions{
RemoteName: "origin",
Progress: os.Stdout,
})

after run the fetch API, nothing changed in my local repo.

Hey @Gluoo,

Repository.Fetch is analogous to git fetch, so it will update references under refs/remotes/, but will leave you local branches and working directory unmodified.

Worktree.Pull is analogous to git pull and will fetch changes from the remote, update references in refs/remotes/, AND merge the changes into your current branch.

Here is an example of how to use the API:

package main

import (
	"fmt"
	"os"

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

// Pull changes from a remote repository
func main() {
	CheckArgs("<path>")
	path := os.Args[1]

	// We instance a new repository targeting the given path (the .git folder)
	r, err := git.PlainOpen(path)
	CheckIfError(err)

	// Get the working directory for the repository
	w, err := r.Worktree()
	CheckIfError(err)

	// Pull the latest changes from the origin remote and merge into the current branch
	Info("git pull origin")
	err = w.Pull(&git.PullOptions{RemoteName: "origin"})
	CheckIfError(err)

	// Print the latest commit that was just pulled
	ref, err := r.Head()
	CheckIfError(err)
	commit, err := r.CommitObject(ref.Hash())
	CheckIfError(err)

	fmt.Println(commit)
}
