如何在 Ansible 中通过文字块标量打破字符串

Question

我在 yaml 脚本中有一个这样的变量：

variable: |
  This is really long long line ---------------------------------------------------------------------------
  And this line is not really long ---------
  And i am just chilling here

我想通过 yamllint 验证我的所有脚本，所以我必须将第一行分成两部分而不更改其内容。 我该怎么做？

如果我尝试从字面上定义它，我会得到这样的结果：

variable: "\
  This is really long long line ---------------------\
  ------------------------------------------------------\n
  And this line is not really long ---------\n
  And i am just chilling here"

我得到这样的信息（注意第二两行中的空格）：

  This is really long long line ---------------------------------------------------------------------------
   And this line is not really long ---------
   And i am just chilling here

其他选项根本不起作用。在这种情况下我如何遵守 yamllint 规则？

Answer 1

您看到此行为是因为您显式添加换行符，然后为文本的其余部分添加回车符。

您可以通过多种方式解决这个问题：

1. 在显式换行符之前添加回车符：

   variable: "\
     This is really long long line ---------------------\
     ------------------------------------------------------
     \nAnd this line is not really long ---------
     \nAnd i am just chilling here"

使用空行添加换行符：

2. variable: "\
     This is really long long line ---------------------\
     ------------------------------------------------------
   
     And this line is not really long ---------
   
     And i am just chilling here"

使用 Jinja 注释来
3. 控制空格：

   variable: |
     This is really long long line ---------------------{#- -#}
     ------------------------------------------------------
     And this line is not really long ---------
     And i am just chilling here

以上所有内容都会给您带来预期的结果：

This is really long long line ---------------------------------------------------------------------------
And this line is not really long ---------
And i am just chilling here
