json - 哪些有效的JSON文件不是有效的YAML 1.1文件？

Question

YAML 1.2是JSON的超集(对于重复的键，一个minor caveat)是JSON的超集，因此任何有效的JSON文件也是有效的YAML文件。但是，YAML 1.1 specification(具有最多library support)没有提到JSON。大多数有效的JSON文件都是有效的YAML 1.1文件，但是我通过试验PyYaml和Python的标准JSON库发现了至少一个异常(exception):

PyYAML将 double 浮点溢出(例如12345e999)解释为字符串，而Python的JSON库将IEEE infinity解释为字符串。

有没有人拥有完整的差异列表，而差异列表比通过测试特定实现中的极端情况更可靠地确定了吗？ (也就是说，通过比较规范？)例如，我想生成JSON字符串，该字符串将由JSON解析器和YAML 1.1解析器以相同的方式进行解释:我必须对字符串施加哪些约束？

Answer 1

参见here(特别是脚注25)。它说:

The incompatibilities were as follows: JSON allows extended character sets like UTF-32 and had incompatible unicode character escape syntax relative to YAML; YAML required a space after separators like comma, equals, and colon while JSON does not. Some non-standard implementations of JSON extend the grammar to include Javascript's /*...*/ comments. Handling such edge cases may require light pre-processing of the JSON before parsing as in-line YAML
