Metagit

Git的Git存储库

如果你

• 有一个满是Git存储库的目录
• 想要对这些存储库的配置进行版本控制
• 像Git一样

那么你可能觉得Metagit很有用。它为管理Git存储库提供了一个类似Git的体验。

演示

初始化Metagit存储库

$ cd ~/projects/    # or wherever you store your Git projects, or use metagit -C
$ metagit init      # creates .metagit, a Git repo where tracked project configs are kept
Initialized Metagit repository in /home/dmtucker/projects
$ metagit status
Untracked projects
  (use "metagit add <project>..." to begin tracking)
	project1/
	project2/

跟踪项目配置的变化

$ metagit add project1/ project2/    # start tracking some projects
$ git -C project1/ remote add foo git@somehost.com:foo/project1.git
$ rm -rf project2/
$ metagit status
Changes
  (use "metagit add/rm <project>..." to accept changes)
  (use "metagit restore <project>..." to undo changes)
	modified: project1
	deleted:  project2

Git跟踪文件中的行。Metagit跟踪项目中的配置。

$ metagit diff
diff --git a/project1 b/project1
index 515f483..93a874c 100644
--- a/project1
+++ b/project1

此示例删除了project2以演示下面的metagit restore，但请注意，仅跟踪配置。如果您需要所有project2，应从备份中恢复。

$ metagit restore project2  # only restores git config! not branches/tags/etc.
$ metagit add project1      # add the project again to keep the changes
$ metagit rm project1       # stop tracking a project (does not affect the actual project)

关于.metagit

.metagit只是您项目文件夹中的另一个Git存储库。它是通过metagit init创建的，该命令自动开始跟踪它。当使用metagit add开始跟踪项目时，该项目的.git/config文件将被复制到.metagit并提交。

$ git -C .metagit log
36cec91 (HEAD -> master) Remove project1
a1ed312 Add project1
185ed15 Add project2
e4d274d Add project1
1e16b5e Add .metagit

提示：将.metagit存储库的副本视为（Metagit）"克隆"您的项目文件夹。例如，将.metagit存储库推送到GitHub以允许轻松设置新的开发机器

$ mkdir ~/projects
$ cd ~/projects/
$ git clone git@github.com:dmtucker/.metagit.git
...
$ metagit restore project2
