如何将子文件夹转换为子存储库？
How to transform a subfolder into a subrepository?
我的存储库中有一个子文件夹，我想将其提取到子存储库中。问题是您必须提交从原始存储库中删除该文件夹中的所有文件，这会在尝试更新到较早版本时产生问题。此外，如果您首先启动了一个子仓库，将其添加到 .hgsub，然后才提交删除原始文件，它也会从子仓库中删除它们（有点混乱）。
是否有更好的方法告诉 Mercurial 文件已移至子存储库，未更改？
在这里保持理智的关键是 Mercurial 的 convert 功能。基本方法已在 http://mercurial.aragost.com/kick-start/en/subrepositories/ 中总结如下：
Converting Folder Into a Subrepository
A project might contain a folder with some code, which at a later point is realized should be used across different projects. This code could of course just be copied to a repository, which the projects could include as subrepository. This would however mean that we would loose our precious history of these files.
The way to do it, is by converting a folder into a repository, using the convert extension and then include this repository as a subrepository in the different projects.

如果这是一个选项，那么您可以考虑使用 convert 两次，将原始存储库分成两部分 - 一个包括所选文件（及其历史记录），另一个不包括它们。
