如何拆分git存储库（按分支）

Question

I started with a piece of code which got split into two small programs each in a different branch.

They share a lot of similarities but I'd like to split them into 2 repos so I can work on both at the same time in an easier fashion. It's annoying to have to commit a change(and get rid of/commit unimortant changes (such as gitignore and makefile flags) before switching context before switching.

It's a pretty simple linear one person history except for that early split and a few unneeded stashes.
What's the best way to accomplish it?

Answer 1

最简单的方法是仅克隆存储库，并可能删除克隆的存储库中不需要的分支。

Answer 2

Even simpler

mkdir program1
cd program1
git init
git pull ../origrepo smallprogram1

rinse, repeat

If you have stuff in a branch history that shouldn't be in that history any more, see git-filter-branch (eg --index-filter 'git rm unwanted-bits' ) and you're good to go

Don't forget to vacuum on your way out ( git gc --prune=... or git repack )
