---

• [x] 必须有自己的名字
• [x] 必须有 issue number（没需求就不做卡）
• [x] 必须有 前缀（feature/refactor/fix/chore/style/docs）
• [x] 前缀后面必须有冒号
• [x] 冒号后面必须有一个空格
• [x] 空格后面必须小写开头
• [ ] 必须不多于70个字符
• [ ] 详细的错误信息

后两个太难，暂时放弃了。

#!/bin/sh

commit_regex="\[Linesh\]\[#\d*\]\s\(Chore\|Feature\|Fix\|Docs\|Style\|Refactor\|Test\):\s[a-z]"
error_msg="Aborting commit, please double check your commit message."

if ! echo "$1" | grep -iqE "$commit_regex" ;
then
        echo "$error_msg" >&2
        exit 1
fi
