Presentation Configurations
===========================

.. confval:: revealjs_use_section_ids

   :Type: ``boolean``
   :Default: ``False``

   If this is set ``True``,

.. confval:: revealjs_script_files

   :Type: ``List[str]``
   :Default: ``[]``
   :Example: ``["presentation.js"]``

   List of sources that render as ``script`` tags.

   There is bundled Reveal.js script at ``revealjs/js/reveal.js``.

   Example:

   .. code-block:: html

      <div>
        <!-- Presentation body -->
      </div>
      <!-- here!! -->
      <script src="_static/revealjs/js/revealjs.js"></script>
      <script src="_static/presentation.js"></script>

.. confval:: revealjs_script_conf

   :Type: ``str or dict``
   :Default: ``None``

   Configuration of Reveal.js presentation.
   This value is used as options of ``Reveal.initialize`` in output files.

   * If value is string type, handle as raw javascript code.
   * If value is dict object, convert to json string at internal.

   .. note::

      For behavior compatibility,
      it appends ``{"scrollActivationWidth": None}`` as default configuration
      when value is dict object or is not set.

      See it: https://github.com/hakimel/reveal.js/releases/tag/5.0.0

   Example 1: case of str

   .. code-block:: py

      revealjs_script_conf = """
      {
          controls: false,
          transition: 'zoom',
      }
      """

   .. code-block:: html

      <div>
        <!-- Presentation body -->
      </div>
      <script src="_static/revealjs/js/revealjs.js"></script>
      <!-- here!! -->
      <script>
        let revealjsConfig = {};
        revealjsConfig = Object.assign(revealjsConfig, {
          controls: false,
          transition: 'zoom',
        });
        revealjs.initialize(revealjsConfig);
      </script>

   Example 2: case of dict

   .. code-block:: py

      revealjs_script_conf = {
          "controls": False,
          "transition": "zoom",
      }

   .. code-block:: html

      <div>
        <!-- Presentation body -->
      </div>
      <script src="_static/revealjs/js/revealjs.js"></script>
      <!-- here!! -->
      <script>
        let revealjsConfig = {};
        revealjsConfig = Object.assign(revealjsConfig, JSON.parse('{"controls": false, "transition": "zoom", "scrollActivationWidth": null}'));
        revealjs.initialize(revealjsConfig);
      </script>

   example 1 and 2 are behaving same.

.. confval:: revealjs_script_plugins

   :Type: ``List[Dict]``
   :Default: ``[]``
