If I have in a template file
I normally write it like this:
{% if i_want_yes %}
# yes
{% else %}
# no
{% endif %}
Would that work for you?

ansible uses the trim_blocks setting when invoking jinja, by default its ‘yes’.
ansible allows for overrides by creating a special header:
#jinja2: trim_blocks: False
#
# {% if i_want_yes %} yes {% else %} no {% endif %}
#
Many thanks for this information. For future reference where is this documented?
The interaction of ansible with jinga2 seems a bit opaque.

https://groups.google.com/forum/#!topic/ansible-project/qHyIjyal_Ic is a
thread where it came up before, which says
you can use a per template header to override this, you can see an
example in the template docs.
https://docs.ansible.com/template_module.html
which is now at http://docs.ansible.com/ansible/template_module.html, and
which only seems to mention it in a note saying
Since Ansible version 0.9, templates are loaded with trim_blocks=True.
and not any actual examples, or any explanation of what trim_blocks does,
so it could be hard to spot this if you didn't already know what you were
looking for.

That page also doesn't mention
http://docs.ansible.com/ansible/playbooks_filters.html, which I've found
to be super useful in turning up examples of Ansible-specific Jinja filters.
