Lightweight presentations for JupyterLab

Installing

pip install jupyterlab-deck

mamba install -c conda-forge jupyterlab-deck # or conda, if you must

See CONTRIBUTING.md for a development installation.

Uninstalling

pip uninstall jupyterlab-deck

mamba remove jupyterlab-deck # or conda if you must

Usage

Get started

After installing, open or create a Notebook.

Other documents work but are not as much fun.

Deck Mode

Start Deck Mode by
in the Notebook Toolbar, click
open the Command Palette and run Start Deck

In Deck Mode, until you configure any slide types, all of your content should appear in a vertically-scrollable stack.

Remote

In Deck Mode, navigate with:
the onscreen remote
if available, up, down, left, right will be available
these correspond to the standard keyboard shortcuts,
→, ↓, ←, ↑
shift+enter executes and advances
the spacebar tries two directions:
space = ↓, or →
shift+space = ↑, or ←

Revealing JupyterLab UX Features

Many of the core JupyterLab UI elements are still available, but hidden by default. Hover over their usual places to reveal them. These include:

the right and left sidebar
the Notebook Toolbar

Hidden JupyterLab UX Features

Some elements are not visible, and cannot be revealed:

the Main Menu
the Status Bar
the Cell Toolbar

Next Steps:
use slideshow types to customize how much of your content appears on-screen.
use layer types to customize foreground/background behavior
use the design tools to customize the appearance of cells
use the slide layout tools to customize the position and size of cells

Exiting Deck Mode

To exit Deck Mode:
from the remote, click the
open the Command Palette and run Stop Deck

Slides

Build a slideshow by changing the slideshow type per cell using the Property Inspector sidebar or the design tools.

type	purpose
`-`	(default) stack underneath the previous cell
`slide`	start a new stack
`fragment`	reveal when activated
`subslide`	start a new cell stack in the optional Y axis
`skip`	hide the cell entirely
`notes`	TBD: moves this cell to the off-screen note viewer

Layers

Pick a layer type from:
the property inspector
or the design tools.

Layers either temporarily or permanently show content, and won't be reached by. Specifying a layer scope will override the slideshow type. Layers have one of the following scopes:

scope	relationship to slides
`deck`	show on all current and future `slide` or `subslides`
`stack`	show until the next `slide`
`slide`	show until the next `slide` or `subslide`
`fragment`	only show until the next `fragment`

Design Tools

In Deck mode, click the ellipsis icon in the bottom left corner

The design tools offer lightweight buttons to:

show/hide the slide layout overlay
set the slideshow type
set the layer type
change a few key appearance properties:
- use the sliders to customize
  - z-index controls the vertical stacking of elements:
    - higher is "closer" to the user
  - opacity controls how vibrant the fonts and colors appear
    - higher is more full
  - zoom controls how big the contents of the cell appear
    - higher is bigger
- un-check the checkbox to restore to the defaults

Slide Layout

After opening the design tools, click the Show Layout button

In slide layout mode, each part of the slide receives an overlay.

Moving a part manually will remove it from the default layout, and allow you to place it anywhere on the screen, but it will keep the same navigation index.

The keyboard shortcuts and remote should still function as normal.

Moving Parts

Click and drag a part overlay to move the part underneath.

Resizing Parts

Click one of the handles in the corners of the part overlay to resize a part.

Reverting Part Move/Resize

After moving a part to a fixed position, click the ↺ button on a part overlay to restore the part to the default layout.

Configuration

Enabling Deck Mode at startup

see the JupyterLab docs about settings overrides.json.

Frequently Asked Questions

Does it work with `notebook 6` aka classic?

No. Use RISE.

Does it work with `notebook 7`?

Mostly. Navigating multiple documents during the same presentation will probably never work, as this is incompatible with the one-document-at-a-time design constraint of the Notebook UX. Each skip to another document will open a new browser tab, though deck should be installed.

Will it generate PowerPoint?

No. This would be a fine third-party extension which could consume notebook metadata created by this extension, jupyterlab-fonts, and nbconvert-compatible slides.
