Git 以分支的方式同时管理多个项目
当然使用万能的Git分支完全可以满足你这么个性化要求( 以分支的形式管理不同项目 )
首页你需要分支是必须要 创建的吧 (对应不同的项目)
那么问题来了，后创建的分支默认是以当前分支为父分支的，像下面这样:"master-dev"的父分支是master
既然Git在创建是默认给我们的新分支指定了父亲，那么可不可以在创建是不需要呢？
强大的Git同样提供了解决方法(创建时提供 --orphan 参数即可 )：git checkout --orphan 分支名
注意：
尽管创建分支时没有了父分支，但创建成功后，原分支的文件会在创建时添加到当前暂存区的，所以需要移除（ 不需要的情况下 ）
然后再将原分支的文件从当前分支仓库中移除，这样你的分支里的文件对于其他分支来说就是独一无二的了(即使不移除原分支的文件，此文件也是新添加到当前分支的，所以跟其他分支没有任何关系)
而其他分支也完全不可能会影响你当前分支的工作( 不存在依赖关系的前提下 )
当切换到PC分支时，Git仓库里的文件也会发生变化，也就实现了我们的目的
不同的分支其实就是不同的目录和文件，跟其他分支没有关系的
提交记录应该是这样子的
可以看到下面pc分支的提交连接线(蓝色)跟其他的连接线(绿色)是不同的
master-dev是在master上创建的子分支( 存在依赖关系 )
以同样的方式创建分支mobile,同样没有父亲， git checkout --orphan mobile
然后在不同分支进行模拟提交,那么提交记录就有可能是这样的
应用场景不同，请谨慎使用，否则提交历史将惨不忍睹
最终的Git分支和对应的目录及文件是这样的,现在你可以在一个Git里愉快的玩耍了
