1. 背景

公司使用的代码仓库是Gitlab，个人代码仓库又是Github。每次提交代码的时候，需要切换不同的提交作者和提交邮箱，非常容易出错。这个脚本是根据repo url自动设置提交作者，避免每次手动配置。

2. 方法

2.1 安装Git

Linux 上安装Git直接使用 sudo yum install git 或者 sudo apt-get install git 命令即可。
Windows 上安装到官网下载安装软件安装即可。安装地址

2.2 添加脚本

在/root/下添加.git-templates/hooks 目录，添加脚本post-checkout，脚本内容如下：

#!/bin/bash

#checkout hook to locally set user name and email based on user defined patterns
#The patterns are matched against the clone url.
#
#Based on http://www.dvratil.cz/2015/12/git-trick-628-automatically-set-commit-author-based-on-repo-url/

function warn {
  echo -e "\n$1 Email and author not initialized in local config!"
}

email="$(git config --local user.email)"
name="$(git config --local user.name)"

if [[ $1 != "0000000000000000000000000000000000000000" || -n $email || -n $name ]]; then
  exit 0
fi

#get remote name:
#  only one: take it
#  more: take "origin", or fail
remote="$([[ $(git remote | wc -l) -eq 1 ]] && git remote || git remote | grep "^origin$")"

if [[ -z $remote ]]; then
  warn "Failed to detect remote."
  exit 0
fi

url="$(git config --local remote.${remote}.url)"

if [[ ! -f ~/.git-clone-init ]]; then
cat << INPUT > ~/.git-clone-init
#!/bin/bash

case "\$url" in
  *@github.com:*    ) email=""; name="";;
  *//github.com/*   ) email=""; name="";;
esac
INPUT
  warn "\nMissing file ~/.git-clone-init. Template created..."
  exit 0
fi
. ~/.git-clone-init

if [[ -z $name || -z $email ]]; then
  warn "Failed to detect identity using ~/.git-clone-init."
  exit 0
fi

git config --local user.email "$email"
git config --local user.name "$name"

echo -e "\nIdentity set to $name <$email>"

2.3 添加配置文件

在/root/.gitconfig文件中（没有的话自行创建）添加如下内容，指定使用的模板：

[user]
[init]
        templatedir = /root/.git-templates
[push]
        default = simple

在/root/.git-clone-init中针对不同的git仓库添加提交作者和邮箱：

#!/bin/bash

case "$url" in
  *@github.com:*    ) email="test@qq.com"; name="xq";;
  *//github.com/*   ) email="test@qq.com"; name="xq";;
  *@gitlab.com:*    ) email="test@google.com"; name="xq";;
  *//gitlab.com/*   ) email="test@google.com"; name="xq";;
esac

2.4 验证

更改脚本post-checkout的权限并执行。 sudo chmod 777 post-checkout sh post-checkout

尝试从github 克隆一个仓库：

[root@yxj-test git_storage]# git clone git@github.com:XueqiangChen/scripts.git
Cloning into 'scripts'...
Warning: Permanently added the RSA host key for IP address '52.74.223.119' to the list of known hosts.

Receiving objects: 100% (8/8), done.

Identity set to XueqiangChen <569503960@qq.com>

可以看到最后一行的打印出来的信息，自动针对该仓库设置了提交作者和邮箱，下一次提交就会使用这个提交作者和邮箱。
