在使用 gitflow 做版本控制系统，发现gitflow的时候只能指定一个master/develop，如果要多分支使用要如何操作呢?那么来看看我是如何给gitflow加料的。
公司都是git作为版本控制，公司一些项目组在用gitflow，但是我们组没有强制， 但是我上月出了一次事故，总结就是分支管理问题，所以开始强迫自己使用gitflow, 以前的项目是一个master和一个develop，自己checkout一个分支，然后merge(不理解的可以看看a-successful-git-branching-model).
问题出现了: 项目有几个主分支和开发分支，比如master_sina, master_qq. master_buzz ,而gitflow的时候只能指定一个master/develop, 这样你start一个feature/hotfix之前就要去.git/config里面修改 [gitflow “branch”]项的相关主分支和开发分支，so不方便。看了下源码，给gitflow加点料
添加功能
当你打开了feature/hotfix分支，但是你不想要它了(当然你可以直接git branch -D xx)，使用git flow hotfix/feature delete ,自动帮你删除这个分支，以便你新建其他分支(git flow只容许你一次存在一个hotfix/feature分支)
你想使用gitflow删除其它存在分支嘛？不需要 git branch -D ，你还可以git flow hotfix/feature delete XX
比如我在init的时候指定了master为master_sina, 而当我想创建master_qq的hotfix，我只需要在start的是否给它取名字是’qq_‘开头的即可，要是有其它的需要你可以直接在源码里面添加对应的内容
例子 git-flow-hotfix 我主要标记我修改的部分
代码如下 复制代码 init() {
require_git_repo
require_gitflow_initialized
gitflow_load_settings
VERSION_PREFIX=$(eval "echo `git config --get gitflow.prefix.versiontag`")
PREFIX=$(git config --get gitflow.prefix.hotfix)
}
