{% for ...} loop creates line breaks

[alanlivio]

The following code with indented lines generates break lines between macros elements

{% for social in config.extra.social %}
  {% set icon = social.icon.replace('/','-') %}
  :{{icon}}: [{{ social.title }}]({{ social.link }})  
{% endfor %} 

The desired behavior works online contatenation

{% for social in config.extra.social %}{% set icon = social.icon.replace('/','-') %}:{{icon}}: [{{ social.title }}]({{ social.link }})  {% endfor %}

try changing {% and %} to {%- and -%}, respectively.

@eyllanesc Spot on: mkdocs-macros uses the standard Jinja2 templating engine. That feature is documented under Whitespace Control.

Thank you both @eyllanesc and @fralau. The %- worked. The issue can be closed.
