Cells not executable in slideshow mode
Opened this issue · 11 comments
Description
After installing jupyterlab-rise, I can see the meta data tags for choosing which kind of slide. However, in slideshow view the slides are not executable, even though they are in Jupyter notebook with RISE
Reproduce
- Create a Jupyter notebook in Jupyter Lab that contains executable Python code.
- Using Common Tools, assign the cells to be Slides
- Invoke slideshow mode
- In slideshow mode edit code and execute cell
Expected behavior
The output of the cell should change based on what has been entered, but it does not.

- Python 3.9.13
Name: jupyterlab
Version: 4.0.5
Summary: JupyterLab computational environment
-

Read the migration plan to Notebook 7 to learn about the new features and the actions to take if you are using extensions.

Please note that updating to Notebook 7 might break some of your extensions.

Just as a data point: I did not manage to reproduce; with the same jupyterlab 4.0.5 and rise 0.40.0,
I can execute cells as expected.
Ubuntu 22.04, Firefox, Python 3.11.5
Ah wait, this could be related to #17: if a code cell already has content,
then that content is executed. But if there is no initial content, whatever
is typed in is ignored, and the cell is executed as an empty cell. Which
looks as if the cell had not been executed.
I can reproduce this.

Try for yourself by running JupyterLab in the following docker image with command (and visit the URL in your browser):

Ah, I should have posted my response in #48 , which I think is more what is going on in my case.
To it looks as if the keyboard shortcut "shift-enter" does not longer execute the cell but navigates to the next slide.
I am having the same issue. The notebook seems to overrule the content in presentation mode, which does the following:
- An empty cell in the notebook cannot be executed in presentation mode. This is what causes the issue stated above by @fiware-austria: execution has no effect and the next cell is entered.
- A cell with content can be executed but changing the content in presentation mode will always produce the same output.
Maybe there is an issue with the separation of "Command Mode" and "Edit Mode"? The cells (in notebook view and presentation mode) are always marked blue but they should be green when in "Edit Mode", if I remember correctly. Also, the shortcuts seem to be "always on", e.g., when I wanted to type # Addition into a cell in presentation mode the speaker view opened when I typed 't'.
I had to downgrade to version 0.2.0 to get it working again. Maybe that helps!
Would be great to get this working, since it is one of the killer-features, that sets rise apart from other presentation tools.

At our institution we used a combination of downgrading and opening the notebook in Nbclassic - not perfect but all functionalities work at the moment.
Just for information: I have been using lately JupyterLab-Deck. There remains a few caveats (JupyterLab 3.6 only, broken space / shift-space navigation with sublides, no conda package), but other than this it has done the job for me.
If your use case allows for JupyterLab 3, I found that cells appear to work normally and run with changes with JupyterLab 3.6.6 and RISE 0.3.0.
FWIW: after PR #62 was merged, I can now reliably edit and execute code in RISE slides.
