PRIME applets

This extension provides an interface to include PRIME applets with relative ease.

What does it do?

This extension provides one Sphinx directives (applet) that can be used to quickly insert a PRIME applet.

Installation

To use this extension, follow these steps:

Step 1: Install the Package

Install the module sphinx-prime-applets package using pip:

pip install sphinx-prime-applets

Step 2: Add to requirements.txt

Make sure that the package is included in your project's requirements.txt to track the dependency:

sphinx-prime-applets

Step 3: Enable in _config.yml

In your _config.yml file, add the extension to the list of Sphinx extra extensions (important: underscore, not dash this time):

sphinx: 
    extra_extensions:
        .
        .
        .
        - sphinx_prime_applets
        .
        .
        .

Applet directive

```{applet}
:url: lines_and_planes/normal_equation_plane_origin
:fig: Images/image_shown_in_print_version.svg
:name: name_that_is_used_to_refer_to_this_figure
:class: dark-light
:title: This title is shown when you full-screen the applet

A plane through the point $P$.
```

::::{note} The url parameter should be the part of the URL after /applet/. So if the full URL is https://openla.ewi.tudelft.nl/applet/lines_and_planes/normal_equation_plane_origin, you should set the parameter to lines_and_planes/normal_equation_plane_origin. ::::

Parameters for an applet

Some parameters can be set for an applet. Only the url and name parameters are required; the rest is optional. It is recommended to add a status to the applet, which can be unreviewed, in-review or reviewed.

```{applet}
:url: lines_and_planes/normal_equation_plane_origin # Required url
:fig: Images/lines_and_planes/normal_equation_plane_origin.svg  # Image shown in print version
:status: reviewed # default is "unreviewed". Other options are "in-review" and "reviewed"
:name: Fig:InnerProduct:ProjectionVectorLine

A title that describes the applet
```

Optional parameters

Parameter	Description	Default
fig	The path to an image that will be shown in the print version of the document	None
title	A string that will be shown as the title of the applet when the applet is in fullscreen mode	""
status	The status of the applet. Can be unreviewed, in-review or reviewed	unreviewed
width	The width of the applet in pixels	100%
height	The height of the applet in pixels	400px

If the fig parameter is not defined, the code will insert the image provided by the applet itself as a fallback.

Control parameters

::::{warning} Work in progress ::::

2D Specific parameters

::::{tip} You should add split-* before the parameter to make it apply to the right scene ::::

Parameter	Description	Default
position2D	The position of the applet in the 2D plane	0,0
zoom2D	The zoom level of the applet in the 2D plane	1

3D Specific parameters

::::{tip} You should add split-* before the parameter to make it apply to the right scene ::::

Parameter	Description	Default
position3D	The position of the applet in the 3D plane	0,0,0
zoom3D	The zoom level of the applet in the 3D plane	1
