问题描述
我有一个Mercurial存储库，其中包含一些相关项目.我只想将这些项目之一分支到其他地方.
I have a Mercurial repository containing a handful of related projects. I want to branch just one of these projects to work on it elsewhere.
克隆仅仅是一部分存储库，这是实现这一目标的正确方法吗?
Is cloning just part of a repository possible, and is that the right way to achieve this?
推荐答案
您想要的是 窄或部分克隆，但是很遗憾，尚不支持此克隆.
What you want is a narrow or partial clone, but this is unfortunately not yet supported.
如果您已经有一个大型存储库，并且意识到将其拆分为几个较小的存储库是有意义的，则可以使用转换扩展名以进行从水银到水银的转换.请注意，这会创建一个 new 存储库foo，并且您不能在your-big-repo和foo之间推/拉.
If you already have a big repository and you realize that it would make sense to split it into several smaller repositories, then you can use the convert extension to do a Mercurial to Mercurial conversion. Note that this creates a new repository foo and you cannot push/pull between your-big-repo and foo.
默认情况下未启用convert extension，因此请将以下内容添加到存储库的hgrc文件或mercurial.ini文件中:
The convert extension is not enabled by default so add the following to your repo's hgrc file or your mercurial.ini file:
[extensions]
hgext.convert=
然后使用
include "libs/foo"
rename "libs/foo" .
(请注意，即使在Windows上也可以使用正斜杠)并运行
(note you can use forward slashes even on Windows) and run
$ hg convert --filemap map.txt your-big-repo foo
这将使foo成为具有your-big-repo中libs/foo文件夹的完整历史记录的存储库.
That will make foo a repository with the full history of the libs/foo folder from your-big-repo.
如果要从your-big-repo中删除所有foo证据，则可以进行另一次转换，在其中使用exclude libs/foo摆脱目录.
If you want to delete all evidence of foo from your-big-repo you can make another conversion where you use exclude libs/foo to get rid of the directory.
当您拥有多个这样的存储库并且想要整体使用它们时，则应查看子存储库.此功能使您可以在结帐中包括其他存储库，这与svn:externals的工作方式类似.请遵循该Wiki页面上的建议.
When you have several repositories like that and you want to use them as a whole, then you should look at subrepositories. This feature lets you include other repositories in a checkout — similarly to how svn:externals work. Please follow the recommendations on that wiki page.
