When writing template files using Jinja2 for Saltstack, I often define some variables at the beginning of the file. For example:
{% set ip = grains['ip4_interfaces']['eth1'][0] %}
{% set domain = pillar['company_domain'] %}
{% set version = pillar['site_version'] %}
{% set site_url = 'www.' + domain %}
[...]
Everything works fine but when opening the generated file, I get a block of empty lines where the jinja code was.
Am I doing something wrong ? If not, is there any way to get rid of those empty lines when using templates ?
