如何克隆一個回購協議(與libgit2)克隆一個git回購(深)
我想要做什麼git clone
做但libgit2
。我可能會問的是git clone
真的深入。
這是我在做什麼至今:
- 初始化回購
- 調整配置文件中添加遠程
- 創建
git_remote
- 下載一個打包文件
- 指數packfile和寫索引(給我們一個.idx文件)
- (編輯)寫所有不同的分支到磁盤。
- (編輯)以某種方式做
git checkout
。
現在我不知道該怎麼做。我唯一的猜測是將.idx
加載到git_index
並使用git_repository_set_index
,但是這並沒有顯示任何文件。
編輯
我測試運行在半克隆回購git checkout master
,並做了工作。現在我只需要找出如何使用libgit2來做到這一點,似乎問題跟蹤器中有一些有用的信息。
編輯2
現在我將添加我當前的代碼中,希望有人總有一天會發現它很有用,在希望是快速啓動代碼,我從來沒有發現。注意:我在這裏使用Obj-C
和Objective-Git
,但它主要是普通的c。

有趣的反饋。這應該以某種方式集成在'gitlib2'庫中。 – VonC
