YAML

YAML is a human friendly data serialization standard for all programming languages.

zh_cn

大小写敏感
使用缩进表示层级关系
缩进时不允许使用Tab键，只允许使用空格。
缩进的空格数目不重要，只要相同层级的元素左侧对齐即可
# 表示注释，从这个字符一直到行尾，都会被解析器忽略

YMAL can use !! to force the type

age: !!int '56'

in js:

{ name: 'ryo', age: 56 }

String

String default is no need use ``

str: this is a string demo

in js:

{ str: 'this is a string demo' }

If there has space or special word in your string, use ’‘ or ”“

name: "hou: ryo"

{ name: 'hou: ryo' }

The diff between ’‘ and ”“ is:

special word in ’‘ will be transfer, but in ”“ will not

double quote: "long \n long story"
single quote: 'long \n long story'

in js:

{ 'double quote': 'long \n long story',
  'single quote': 'long \\n long story' }

单引号之中如果还有单引号，必须连续使用两个单引号转义。

name: 'mary''s song'

in js:

{ name: 'mary\'s song' }

字符串可以写成多行，从第二行开始，必须有一个单空格缩进。换行符会被转为空格

long string
 a
 ha
 ha

in js:

'long string a ha ha'

多行字符串可以使用|保留换行符，也可以使用>折叠换行

this: |
 angle
 beats
that: >
 little
 busters

in js:

{ this: 'angle\nbeats\n', that: 'little busters\n' }

+表示保留文字块末尾的换行，-表示删除字符串末尾的换行

one: |
 Spring

two: |+
 Summer


three: |-
 Autumn

in js:

{ one: 'Spring\n', two: 'Summer\n\n\n', three: 'Autumn' }

String can insert HTML
