引用YAML（对于Travis CI）

问题描述

我如何在YAML中逃脱一条线？我想要 json ='{title：travis_saulshanabrook_site，key：'$（cat〜/ .ssh / id_rsa.pub）'}'
在列表中，但是我无法将其解析成字符串。我可以把单引号放在整条线上，但是我将不得不逃避我的字符串中的每一个引号，使其很难阅读。字符串将作为中的bash命令运行

$ b $最好的解决方案是使用 | 指示符，使用 - 修饰符删除最终新队。这样就不需要额外的引用。

如果这个标量恰好是YAML文件中唯一使用的标签：

pre> |
json ='{title：travis_saulshanabrook_site，key：'$（cat〜/ .ssh / id_rsa.pub） $'


如果它是键的映射值 abc ：

  abc：|  -  
 json ='{title：travis_saulshanabrook_site关键：'$（cat〜/ .ssh / id_rsa.pub）'''
  

或者如果它是列表的一部分：

   -  |  -  
 json ='{title：travis_saulshanabrook_site ，key：'$（cat〜/ .ssh / id_rsa.pub）'}'
  

How would I escape a whole line in YAML? I want to have json='{"title": "travis_saulshanabrook_site","key": "'$(cat ~/.ssh/id_rsa.pub)'"}' in a list, but I can't get it to parse into a string. I can put single quotes around the whole line, but then I would have to escape every single quote in my string, making it very hard to read. The string will be run as a bash command in Travis CI

解决方案

The most elegant solution is to use the literal style | indicator, with the - modifier to strip the final newline. That way there are no extra quotes necessary.

If this scalar happens to be the only thing in a YAML file use:

|-
  json='{"title": "travis_saulshanabrook_site","key": "'$(cat ~/.ssh/id_rsa.pub)'"}'

if it is a mapping value for key abc:

abc: |-
  json='{"title": "travis_saulshanabrook_site","key": "'$(cat ~/.ssh/id_rsa.pub)'"}'

or if it is part of a list:

- |-
  json='{"title": "travis_saulshanabrook_site","key": "'$(cat ~/.ssh/id_rsa.pub)'"}'
