------------------------
Setting an empty mapper
------------------------

.. currentmodule:: pycif.plugins.models.template

Before going further, let's initialize properly the ``mapper``.
The ``template`` proposes an example of working ``mapper`` with
no inputs nor outputs.

.. autofunction:: ini_mapper
  :noindex:

The corresponding Yaml to do it is the one below:

.. literalinclude:: ../yml/3_emptymapper.yml
    :linenos:
    :language: yaml

Compared to the yaml from previous steps, the paragraph ``obsoperator`` was added.
This paragraph forces to initialize an execution pipeline, hence requires
the initialization of the ``mapper``.
Please consult the corresponding :doc:`obsoperator page </documentation/plugins/obsoperators/index>`
for further details.
