HAML中的多行字符串 [英] Multiline string in HAML

问题描述

因为我不希望任何行都超过80列，所以我想将最后一行分成两行.按照建议的

Because I don't want any of my lines to be wider than 80 columns, I want to split the last line into two lines. Adding a comma at the end of the line works as suggested here but then the comma appears inside the string. Is there a nice and clean way of doing this with HAML?

- if object.errors.any?
  %section.form_error_message
    %h4.form_error_message__title
      = "#{pluralize(object.errors.size, 'errors')} prevented this form from submitting. Please fix these errors and try again."

我希望将它们全部塞入该屏幕截图左侧的80列中.

I want it all to be tucked inside 80 columns like they are on the left of this screenshot.

推荐答案

Haml支持多行序列使用|字符:

- if object.errors.any?
  %section.form_error_message
    %h4.form_error_message__title
      = "#{pluralize(object.errors.size, 'errors')} prevented this form from |
        submitting. Please fix these errors and try again."                  |

在这种情况下，您实际上并不需要它，您可以直接使用插值以纯文本格式，您不需要=:

In this case you don’t really need this though, you can use interpolation directly in plain text, you don’t need the =:

- if object.errors.any?
  %section.form_error_message
    %h4.form_error_message__title
      #{pluralize(object.errors.size, 'errors')} prevented this form from
      submitting. Please fix these errors and try again.

(此命令的输出会稍有不同，因为它将包含换行符.不过，除非在例如<pre>标记内，否则您不会在呈现的HTML中注意到这一点.)

(The output of this will be slightly different, as it will include the newline. You should’t notice that in the rendered HTML though, unless you are e.g. inside <pre> tags.)
