  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:
 
  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)
  }
  # 增加help的选项说明
  usage() {
      echo "usage: git flow hotfix [list] [-v]"
      echo "       git flow hotfix start [-F] <version> [<base>]"
      echo "       git flow hotfix finish [-Fsumpk] <version>"
      echo "       git flow hotfix publish <version>"
      echo "       git flow hotfix delete [branch]"
      echo "       git flow hotfix track <version>"
  }
  cmd_default() {
      cmd_list "$@"
  }
  
  cmd_list() {
      DEFINE_boolean verbose false 'verbose (more) output' v
      parse_args "$@"
  
      local hotfix_branches
      local current_branch
      local short_names
      hotfix_branches=$(echo "$(git_local_branches)" | grep "^$PREFIX")
      if [ -z "$hotfix_branches" ]; then
          warn "No hotfix branches exist."
                  warn ""
                  warn "You can start a new hotfix branch:"
                  warn ""
                  warn "    git flow hotfix start <version> [<base>]"
                  warn ""
          exit 0
      fi
      current_branch=$(git branch --no-color | grep '^* ' | grep -v 'no branch' | sed 's/^* //g')
      short_names=$(echo "$hotfix_branches" | sed "s ^$PREFIX  g")
  
      # determine column width first
      local width=0
      local branch
      for branch in $short_names; do
          local len=${#branch}
          width=$(max $width $len)
      done
      width=$(($width+3))
  
      local branch
      for branch in $short_names; do
          local fullname=$PREFIX$branch
          local base=$(git merge-base "$fullname" "$MASTER_BRANCH")
          local master_sha=$(git rev-parse "$MASTER_BRANCH")
          local branch_sha=$(git rev-parse "$fullname")
          if [ "$fullname" = "$current_branch" ]; then
              printf "* "
          else
              printf "  "
          fi
          if flag verbose; then
              printf "%-${width}s" "$branch"
              if [ "$branch_sha" = "$master_sha" ]; then
                  printf "(no commits yet)"
              else  --phpfensi.com
                  local tagname=$(git name-rev --tags --no-undefined --name-only "$base")
                  local nicename
                  if [ "$tagname" != "" ]; then
                      nicename=$tagname
                  else
                      nicename=$(git rev-parse --short "$base")
                  fi
                  printf "(based on $nicename)"
              fi
          else
              printf "%s" "$branch"
          fi
          echo
      done
  }
  
  cmd_help() {
      usage

      FLAGS "$@" || exit $?
      eval set -- "${FLAGS_ARGV}"
      # read arguments into global variables
      VERSION=$1
      BRANCH=$PREFIX$VERSION
  这里就是我多master/develop的技巧,我这里会判断要新建的分支的前缀,要是qq_开头就会基于master_qq和develop_qq创建分支,所以你可以根据你的需要在这里加一些方法.
