go-git logo GoDoc Build Status Go Report Card

go-git is a highly extensible git implementation library written in pure Go.

It can be used to manipulate git repositories at low level (plumbing) or high level (porcelain), through an idiomatic Go API. It also supports several types of storage, such as in-memory filesystems, or custom implementations, thanks to the Storer interface.

It's being actively developed since 2015 and is being used extensively by Keybase, Gitea or Pulumi, and by many other libraries and tools.

Project Status

After the legal issues with the src-d organization, the lack of update for four months and the requirement to make a hard fork, the project is now back to normality.

The project is currently actively maintained by individual contributors, including several of the original authors, but also backed by a new company, gitsight, where go-git is a critical component used at scale.

Comparison with git

go-git aims to be fully compatible with git, all the porcelain operations are implemented to work exactly as git does.

git is a humongous project with years of development by thousands of contributors, making it challenging for go-git to implement all the features. You can find a comparison of go-git vs git in the compatibility documentation.

Installation

The recommended way to install go-git is:

import "github.com/sgnl-ai/go-git" // with go modules enabled (GO111MODULE=on or outside GOPATH)
import "github.com/go-git/go-git" // with go modules disabled

Examples

Please note that the CheckIfError and Info functions used in the examples are from the examples package just to be used in the examples.

Basic example

A basic example that mimics the standard git clone command

// Clone the given repository to the given directory
Info("git clone https://github.com/go-git/go-git")

_, err := git.PlainClone("/tmp/foo", false, &git.CloneOptions{
    URL:      "https://github.com/go-git/go-git",
    Progress: os.Stdout,
})

CheckIfError(err)

Outputs:

Counting objects: 4924, done.
Compressing objects: 100% (1333/1333), done.
Total 4924 (delta 530), reused 6 (delta 6), pack-reused 3533

In-memory example

Cloning a repository into memory and printing the history of HEAD, just like git log does

// Clones the given repository in memory, creating the remote, the local
// branches and fetching the objects, exactly as:
Info("git clone https://github.com/go-git/go-billy")

r, err := git.Clone(memory.NewStorage(), nil, &git.CloneOptions{
    URL: "https://github.com/go-git/go-billy",
})

CheckIfError(err)

// Gets the HEAD history from HEAD, just like this command:
Info("git log")

// ... retrieves the branch pointed by HEAD
ref, err := r.Head()
CheckIfError(err)


// ... retrieves the commit history
cIter, err := r.Log(&git.LogOptions{From: ref.Hash()})
CheckIfError(err)

// ... just iterates over the commits, printing it
err = cIter.ForEach(func(c *object.Commit) error {
	fmt.Println(c)
	return nil
})
CheckIfError(err)

Outputs:

Overview

A highly extensible git implementation in pure Go.

go-git aims to reach the completeness of libgit2 or jgit, nowadays covers the majority of the plumbing read operations and some of the main write operations, but lacks the main porcelain operations such as merges.

It is highly extensible, we have been following the open/close principle in its design to facilitate extensions, mainly focusing the efforts on the persistence of the objects.

Commit stores the current contents of the index in a new commit along with a log message from the user describing the changes.

func (*Worktree) Grep 

func (w *Worktree) Grep(opts *GrepOptions) ([]GrepResult, error)

Grep performs grep on a worktree.

func (*Worktree) Move 

func (w *Worktree) Move(from, to string) (plumbing.Hash, error)

Move moves or rename a file in the worktree and the index, directories are not supported.

func (*Worktree) Pull 

func (w *Worktree) Pull(o *PullOptions) error

Pull incorporates changes from a remote repository into the current branch. Returns nil if the operation is successful, NoErrAlreadyUpToDate if there are no changes to be fetched, or an error.

Pull only supports merges where the can be resolved as a fast-forward.

func (*Worktree) PullContext 

func (w *Worktree) PullContext(ctx context.Context, o *PullOptions) error

PullContext incorporates changes from a remote repository into the current branch. Returns nil if the operation is successful, NoErrAlreadyUpToDate if there are no changes to be fetched, or an error.

Pull only supports merges where the can be resolved as a fast-forward.

The provided Context must be non-nil. If the context expires before the operation is complete, an error is returned. The context only affects the transport operations.

func (*Worktree) Remove 

func (w *Worktree) Remove(path string) (plumbing.Hash, error)

Remove removes files from the working tree and from the index.

func (*Worktree) RemoveGlob 

func (w *Worktree) RemoveGlob(pattern string) error

RemoveGlob removes all paths, matching pattern, from the index. If pattern matches a directory path, all directory contents are removed from the index recursively.

func (*Worktree) Reset 

func (w *Worktree) Reset(opts *ResetOptions) error

Reset the worktree to a specified state.

func (*Worktree) ResetSparsely 

func (w *Worktree) ResetSparsely(opts *ResetOptions, dirs []string) error

func (*Worktree) Status 

func (w *Worktree) Status() (Status, error)

Status returns the working tree status.

func (*Worktree) Submodule 

func (w *Worktree) Submodule(name string) (*Submodule, error)

Submodule returns the submodule with the given name

func (*Worktree) Submodules 

func (w *Worktree) Submodules() (Submodules, error)

Submodules returns all the available submodules
