No Cell Toolbar View; All slides end up on Same Page

[drscotthawley]

Description

This is a pair of issues together.

1. There is no View > Cell Toolbar option as is expected in RISE
2. Opening a saved RISE notebook file and selecting View > Render as Reveal Slideshow results in all cells that had been designated as slides opening on the same screen together, i.e. no slide divisions.

(3.) Re. point 1, There are no usage instructions to describe how to use this, differently from the original RISE.

Reproduce

I would have tried to use your examples/README.ipynb as an example but it refuses to load.

1. Go to View.
2. Try to click on Cell Toolbar
3. Search README for any usage instructions or links to additional documentation
4. Try to load examples/README.ipynb
5. See error File Load Error for README.ipynb Unreadable Notebook: README.ipynb <ValidationError: "Notebook could not be converted from version 1 to version 2 because it's missing a key: cells">

Alternatively,

1. Try to load an existing .ipynb slideshow
2. Go to View > Render as Reveal Slideshow
3. See that separate slides are all appearing run together on one page.

Expected behavior

• Some way of designating slides.
• Documentation to describe differences from original RISE
• Ability to render separate slides as separate slides

Context

• Python package version:
  Results of conda list extension_name or pip show extension_name:

$ pip show extension_name
WARNING: Package(s) not found: extension_name

• Extension version:

Hi @drscotthawley,

1. To edit the rise cell metadata, you can use the property inspector in the right jupyterlab toolbar. This is indeed deviates from the original rise in Jupyter notebook, but is consistent with how jupyterlab gives access to cell metadata for other
   purposes. Once you have discovered it, it's fairly natural.

2. I did not manage to reproduce. My slides appear properly separated. Could you provide an example notebook, or a screencast?

As a heavy rise user, I am already grateful that something is starting to exist. But there is indeed still a long way to go, including for documentation.

[surfaceowl]

@drscotthawley -- same thing happened to me after creating a new notebook with versions below. The current version of RISE installs with the "slide type" attribute of each cell defaulted to null (actually it's "-"). As a result, all the cells appear on the same page when you run RISE. The trick is to 1) click on the icon of small gears for each notebook cell (see red arrow in image below), 2) look under "common tools" immediately to the left of the small gears, then 3) find the "slide type" drop down box and change it to "slide" (or whatever other choice is right for that cell.

The versions I used are:
jupyterlab==4.0.6
jupyterlab-rise==0.41.0



screenshot

@nthiery -- would be great to document maybe just on the Readme for now, since the interface is so different from older RISE versions running in notebook.




Here is result

[ibgp2]

@surfaceowl Thanks, your message helps a lot, because finding this menu isn't very natural!

Please also note some RISE shortcuts also works:

• Shift-i, set a cell to "slide"
• Shift-b, set a cell to "subslide"
• Shift-g, set a cell to "fragment"

Note that if this cell is a "slide", Shift-i does not revert a cell to "-" (rise 5.7.1, jupyterlab_rise 0.42.0, jupyterlab 4.1.4).
I don't know whether there is a shortcut to set a cell to "-", so currently, I use the "gear" icon in the right panel.
