How to force line break in Symfony2 translation file

Question

In my messages.en.yml I have an entry that is used for an email body which is in plaintext, so I cannot use any HTML tags. Now when I need a line break and I add a blank line after, the line break appears in my email body.

But when I try to do a line break with a non empty line following, it does not break the lines.

email:
    subject: My Subject
    message: >
        Hello %name%,

        This is my second line

        Best regards,

I've tried to play around with HTML tags or with the \n which I know from PHP. But if I use <br> or <br /> in the translation file and apply the |raw filter in my twig file, the HTML tags still appear in my email body. And also if I use \n to force a line break, no line break is given and instead, the \n appear in my email as well.

Now how can I force the line break if a non empty line is following?

Answer 1

Use |

email:
    subject: My Subject
    message: |
        Hello %name%,

        This is my second line

In your translations file (e.g. messages.en.yml):

your
   translation      
      key:
         here: |
                Lorem ipsum.

                CRMPICCO.

                www.crmpicco.co.uk.

Accessing it in your Twig template:

{{ 'your.translation.key.here'|trans|nl2br }}
