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 type of storage, such as in-memory filesystems, or custom implementations thanks to the Storer interface.

It's being actively develop since 2015 and is being use extensively by source{d} and Keybase, and by many other libraries and tools.

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 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:

go get -u gopkg.in/src-d/go-git.v4/...

We use gopkg.in for having a versioned API, this means that when go get clones the package, is the latest tag matching v4.* cloned and not the master branch.

Examples

Please note that the functions CheckIfError and Info 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/src-d/go-git")

_, err := git.PlainClone("/tmp/foo", false, &git.CloneOptions{
    URL:      "https://github.com/src-d/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/src-d/go-siva")

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

CheckIfError(err)

// Gets the HEAD history from HEAD, just like does:
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.
