Description

While working on a profile with exported preferences from tiki-admin.php?page=profiles&cookietab=2 I have realized when trying to apply that YAML code as a local profile using the following command:
php console.php profile:apply my-preferences profiles

the result is fatal error:

PHP Fatal error:  Unsupported operand types in /var/www/clients/client1/web16/subdirs/.../lib/core/Horde/Yaml/Loader.php on line 363


The problem is my profile YAML file (which I saved as my-preferences.yml in a profiles/ dir) contains one line preferences like this:

preferences:
 main_shadow_end: {if $page eq "HomePage"}</div>{/if}
 main_shadow_start: {if $page eq "HomePage"}<div class="home">{/if}
 ...


When I change it to the multiline syntax (notice the "|" character and new indented line):

preferences:
 main_shadow_end: |
  {if $page eq "HomePage"}</div>{/if}
 main_shadow_start: |
  {if $page eq "HomePage"}<div class="home">{/if}
 ...

then it works with no fatal error anymore!

What can we do to fix this? Fix the YAML exporter somehow to detect if there are any operands like > or < and if yes export the preference value as multiline even when it is just one line of text?

Anything else?

Thanks for your time reviewing this bug.
