Git配置别名中的多行函数无法生效，求可行实现方案

你的Git别名无法工作主要是双引号嵌套冲突、变量未正确引用这两个核心问题，以下是修正后的两种可行实现方式：

方式一：多行写法（推荐，可读性高） #

在.gitconfig中使用多行定义时，需要转义echo里的双引号，同时给分支变量加上引号避免空格问题：

[alias]
reset-dev = "!f() { \
    current_branch=$(git rev-parse --abbrev-ref HEAD); \
    echo \"Work finished on branch '$current_branch'. Now resetting back to 'develop' and deleting the branch.\"; \
    read -p \"Do you want to continue? (Yes/No): \" choice; \
    case \"$choice\" in \
      [Yy]|[Yy][Ee][Ss]) \
        echo \"Continuing...\"; \
        git checkout develop; \
        git pull origin develop; \
        git branch -d \"$current_branch\"; \
        echo \"Switched to 'develop' and deleted $current_branch.\"; \
        echo \"Reset complete.\";; \
      *) \
        echo \"Operation aborted.\"; exit 1;; \
    esac \
}; f"

修改说明： #

• 给每行末尾加上反斜杠\，确保多行被识别为单个命令字符串
• 转义echo语句内的双引号\"，避免和外层的双引号冲突
• 分支变量$current_branch引用时加上双引号"$current_branch"，兼容带空格的分支名
• case语句的结束分支从;;;改为;;（符合bash语法规范）
• 移除命令后的注释，避免干扰脚本执行

方式二：单行写法 #

如果偏好单行定义，需要把所有换行替换为分号，同时处理好引号转义和变量引用：

[alias]
reset-dev = "!f() { current_branch=$(git rev-parse --abbrev-ref HEAD); echo \"Work finished on branch '$current_branch'. Now resetting back to 'develop' and deleting the branch.\"; read -p \"Do you want to continue? (Yes/No): \" choice; case \"$choice\" in [Yy]|[Yy][Ee][Ss]) echo \"Continuing...\"; git checkout develop; git pull origin develop; git branch -d \"$current_branch\"; echo \"Switched to 'develop' and deleted $current_branch.\"; echo \"Reset complete.\";; *) echo \"Operation aborted.\"; exit 1;; esac; }; f"

额外优化建议： #

• 可以在脚本开头加判断，避免误删develop分支：if [ "$current_branch" = "develop" ]; then echo "Cannot delete develop branch."; exit 1; fi;
• 如果需要强制删除未合并的分支，把git branch -d改为git branch -D
