yaml多行字符串不解析

Question

我不明白为什么第一个YAML多行字符串解析，但是 嵌入为值的第二个不解析：

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

xmas: {   
   day: "Dec 25",
   another_ignore_newlines: >
            this is really a
            single line of text
            despite appearances
   cleanup: "Dec 26"
}

这可能只是YAML的另一个“奇怪”，但为什么.....？

Answer 1

In YAML it is not allowed to have block style nodes nested within flow style。并且xmas的值是一个流样式映射，它包含another_ignore_newlines的（折叠文字）块样式标量值。 这不起作用，因为在,之前的行上也应该有一个尾随cleanup。

尝试删除{和}以及"Dec 25"之后的尾随逗号：

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

xmas:
   day: "Dec 25"
   another_ignore_newlines: >
            this is really a
            single line of text
            despite appearances
   cleanup: "Dec 26"
