您如何在YAML中阻止评论？ [英] How do you do block comments in YAML?

问题描述

如何在YAML中注释行块？

How do I comment a block of lines in YAML?

推荐答案

YAML支持内联注释，但不支持块注释。

YAML supports inline comments, but does not support block comments.

来自维基百科：

注释以数字符号（＃）开头，可以在一行的任何地方开始，并继续到行尾

Comments begin with the number sign ( # ), can start anywhere on a line, and continue until the end of the line

与JSON的比较，也来自维基百科：

A comparison with JSON, also from Wikipedia:

语法上的区别微妙而很少在实践中出现：JSON允许扩展字符集（如UTF-32），YAML要求在逗号，等号和冒号等分隔符后留一个空格，而JSON则不允许，并且一些非标准的JSON实现将语法扩展为包括Java语言的 / * ... * / 注释。处理此类极端情况可能需要在将JSON解析为嵌入式YAML之前对JSON进行少量预处理。

The syntax differences are subtle and seldom arise in practice: JSON allows extended charactersets like UTF-32, YAML requires a space after separators like comma, equals, and colon while JSON does not, and 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.

# you'll need three pound signs
