# 纯量hello
# 数组- Cat- Dog- Goldfish
# 对象animal: pets

# 单引号name: 'Hi,\nTom'
# 双引号name: "Hi,\nTom"

# YAML允许使用个感叹号(!)强制转换数据类型# 单叹号通常是自定义类型，双叹号是内置类型money: !!str123
date: !Booleantrue

# 不适用引号name: Tom
# 使用单引号name: 'Tom'
# 使用双引号name: "Tom"

debug: truedebug: false

date: ~date: null

# 使用iso-8601标准表示日期date: 2018-01-01t16:59:43.10-05:00

# 注意“|”与文本之间须另起一行# 使用|标注的文本内容缩进表示的块，可以保留块中已有的回车换行value: |  hello  world!
# 输出结果# hello 换行 world！！

# +表示保留文字块末尾的换行# -表示删除字符串末尾的换行value: |hello
value: |-hello
value: |+hello
# 输出结果# hello\n hello hello\n\n

# 注意“>”与文本之间的空格# 使用>标注的文本内容缩进表示的块，将块中回车替换为空格最终连接成一行value: > helloworld!
# 输出结果# hello 空格 world！

# 复制代码注意*引用部分不能追加内容# 使用&定义数据锚点，即要复制的数据# 使用*引用锚点数据，即数据的复制目的地name: &a yamlbook: *abooks:   - java   - *a   - python
# 输出结果book： yamlbooks：[java, yaml, python]
