go-git GoDoc Build Status Build status codebeat badge

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.

... is this production ready?

The master branch represents the v4 of the library, it is currently under active development and is planned to be released in early 2017.

If you are looking for a production ready version, please take a look to the v3 which is being used in production at source{d} since August 2015 to analyze all GitHub public repositories (i.e. 16M repositories).

We recommend the use of v4 to develop new projects since it includes much new functionality and provides a more idiomatic git API


The recommended way to install go-git is:

go get -u


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")

_, err := git.PlainClone("/tmp/foo", false, &git.CloneOptions{
    URL:      "",
    Progress: os.Stdout,



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")

r, err := git.Clone(memory.NewStorage(), nil, &git.CloneOptions{
    URL: "",


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

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

// ... retrieves the commit object
commit, err := r.CommitObject(ref.Hash())

// ... retrieves the commit history
history, err := commit.History()

// ... just iterates over the commits, printing it
for _, c := range history {

    readwriter: fix bug when writing index. (#10)

    When using ReadWriter on an existing siva file, absolute offset for
    index entries was not being calculated correctly.
