1.块符号（普通、流样式、标量）：删除块后，换行符变为空格和额外换行符

---
# Note: It has 1 new line after the string
content:
    Arbitrary free text
    over multiple lines stopping
    after indentation changes...

...

等效JSON

{
 "content": "Arbitrary free text over multiple lines stopping after indentation changes..."
}

2.文字块标量：文字块标量|将包括换行符和任何尾随空格。但删除了额外的

块后面的换行符。

---
# After string we have 2 spaces and 2 new lines
content1: |
 Arbitrary free text
 over "multiple lines" stopping
 after indentation changes...  


...

等效JSON

{
 "content1": "Arbitrary free text\nover \"multiple lines\" stopping\nafter indentation changes...  \n"
}

3.+带文字块标量的指示符：在块后保留额外的换行符

---
# After string we have 2 new lines
plain: |+
 This unquoted scalar
 spans many lines.


...

等效JSON

{
 "plain": "This unquoted scalar\nspans many lines.\n\n\n"
}

4.–带有文字块标量的指示符：–表示删除字符串末尾的换行符。

---
# After string we have 2 new lines
plain: |-
 This unquoted scalar
 spans many lines.


...

等效JSON

{
 "plain": "This unquoted scalar\nspans many lines."
}

5.折叠块标量（>）：

将换行符折叠为空格，但在块之后删除多余的换行符。

---
folded_newlines: >
 this is really a
 single line of text
 despite appearances


...

等效JSON

{
 "fold_newlines": "this is really a single line of text despite appearances\n"
}

您可能不相信，但YAML也可以执行多行键：

?
 >
 multi
 line
 key
:
  value

对于字符串可能包含空格或不包含空格的情况，我更喜欢双引号和带反斜杠的换行符：

key: "String \
  with long c\
  ontent"

但请注意，如果连续行以空格开头，则需要进行转义（因为它将在其他地方被剥离）：

key: "String\
  \ with lon\
  g content"

如果字符串包含换行符，则需要用C样式\n编写。

另请参见此问题。

在Jekyll项目中的YAML文件中，上述解决方案都不适用于我。在尝试了许多选项后，我意识到使用<br>的HTML注入也可以，因为最终所有内容都呈现为HTML：

姓名：|在一个叫La Mancha的村庄<br>我不想记住他的名字<br>。

至少它对我有用。不知道与这种方法相关的问题。

要连接没有空格的长行，请使用双引号并用反斜杠转义换行符：

key: "Loremipsumdolorsitamet,consecteturadipiscingelit,seddoeiusmodtemp\
  orincididuntutlaboreetdoloremagnaaliqua."
