go-gitGit 的 Go 语言实现
go-git 是一个 Go 语言实现的高度可扩展的 Git 实现库。可以使用友好的 API 来管理 Git 的仓库。支持不同类型的存储,包括内存文件系统,也可以通过接口 Storer
实现对存储的扩展。
该项目从 2015 年开始开发。项目旨在兼容 git ,所有的操作实现与git完全一样。两者的兼容比较请阅读 compatibility documentation.
基本示例
一个实现 git clone 的最基本示例:
// 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)
输出结果:
Counting objects: 4924, done.
Compressing objects: 100% (1333/1333), done.
Total 4924 (delta 530), reused 6 (delta 6), pack-reused 3533
实现内存存储的示例
将 git 仓库克隆到内存中,并打印 HEAD 的历史记录,类似 git log :
// 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 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)
输出结果:

index entries was not being calculated correctly.
