Viewing documentation

Once activated, visit the front view of your calendar. A box will be displayed in the top-left corner of the screen. This box displays documentation and details about the templates used in the current view.

The documentation includes:

  1. Plugin file: The path to the selected template file in the plugins directory.
  2. Theme path: The file path where custom template overrides should go in your theme.

It also displays relevant functions and actions can hook into to customize the template:

  1. pre_html: Allows users to filter the HTML by the template name before rendering.
  2. before_include: Fires an action before including the template file.
  3. after_include: Fires an action after including the template file.
  4. template_html: Allows users to filter the final HTML by the template name before render.

Anchoring the documentation

The documentation box appears when hovering over an element, then hides when the element is no longer hovered. Hold the CTRL key to keep the documentation box open.

Copying documentation

Clicking any input contained in the documentation box will copy the content, providing you with a quick way to grab the information.
