Export subtree in Git with history
提问by matpie
I have a folder in my Git repository that I'd like to move out in to its own repository. Is it possible to move the history of that folder along with the folder?
我的 Git 存储库中有一个文件夹，我想将它移到它自己的存储库中。是否可以随文件夹移动该文件夹的历史记录？
I've previously been doing just a git rm -r --cached subfolder/and then git initon the subfolder. However, the history is not imported in to the new repository.
我以前一直在做一个git rm -r --cached subfolder/然后git init在子文件夹上。但是，历史不会导入到新的存储库中。

Quoting an example from git-filter-branch(1)
引用一个例子 git-filter-branch(1)
To rewrite the repository to look as if foodir/ has been its project root, and discard all other history:
重写存储库以使其看起来好像 foodir/ 已经是它的项目根目录，并丢弃所有其他历史记录：
git filter-branch --subdirectory-filter foodir -- --all
Thus you can, e.g., turn a library subdirectory into a repository of its own. Note the -- that separates filter-branch options from revision options, and the --all to rewrite all branches and tags.
例如，您可以将库子目录转换为它自己的存储库。请注意将过滤器分支选项与修订选项分开的 --，以及用于重写所有分支和标签的 --all。
