Question

I want to do something like this:

{% if compress %}{% spaceless %}{% endif %}
...
{% if compress %}{% endspaceless %}{% endif %}

I’m trying to pass ['compress' => true] to the template from PHP to turn on spaceless mode. But it causes an error; template tags need to be nested properly.

Is there any technique that would let me turn spaceless on/off from PHP?

You would have to restructure your template to do something like this instead.

{% import _self as example %}
{% macro stuff(obj) %}
  output stuff with {{ obj.name }}, etc...
{% endmacro %}

{% if compress %}
  {% spaceless %}
    {{ example.stuff(bla) }}
  {% endspaceless %}
{% else %}
    {{ example.stuff(bla) }}
{% endif %}

Using macros avoids you have to duplicate the content. The import statement at the top is important, so don’t forget it.
