See CONTRIBUTING.md for a development installation.

Uninstalling

pip uninstall jupyterlab-slideshow

or

mamba remove jupyterlab-slideshow # 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

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.

Will it generate single-document static HTML presentations?

No. Use nbconvert, but no layers or style customization will work.

For a full static viewing experience, try something like JupyterLite.

Will it generate PDF?

Not yet.
