On-demand logging
=================

.. versionadded:: 2017.7.0

The sole purpose of this module is logging messages in the (proxy) minion.
It comes very handy when debugging complex Jinja templates, for example:

.. code-block:: jinja

    {%- for var in range(10) %}
      {%- do salt.log.info(var) -%}
    {%- endfor %}

CLI Example:

.. code-block:: bash

    salt '*' log.error "Please don't do that, this module is not for CLI use!"
