When I execute an IPython notebook to a reveal.js presentation using
ipython nbconvert mynotebook.ipynb --to slides --post serve
I am getting all the content as a single slide. How do I separate my content into several slides?
I tried using --- (hinted in this video), \n\n\n and === inside the notebook (as separate cells and before my titles), but it didn't change anything. I know that for a Markdown input file in reveal.js one can set the data-separator option, but the generated html file doesn't seem to include the content as Markdown, but inlines everything using HTML tags, so I don't know how to make IPython generate new slide tags where I want them.
(I'm using IPython 1.1 installed via pip)
回答1:
In main toolbar, select the "slideshow" cell toolbar. Then select if you want each cell to be a new "slide", "subslide","fragment"...etc

The correct answer is Matt's answer. You need to use "slideshow" cell and specify the cell type with "slide", "subslide","fragment".
However, reveal.js-3.0.0 is now the latest release, and it doesn't work with IPython Notebook slides.
The browser dev tools give ReferenceError: Reveal is not defined
One solution is to specify some older version
ipython nbconvert your_nobetook.ipynb --to slides --reveal-prefix "http://cdn.jsdelivr.net/reveal.js/2.6.2" --post serve
And even better option is to clone the reveal.js repo into directory of your_notobook.ipynb and checkout version 2.6.2 via git
git clone https://github.com/hakimel/reveal.js.git
cd reveal.js
git checkout 2.6.2
afterwards this should work
ipython nbconvert your_notobook.ipynb --to slides --post serve
This solution works offline.
As of this moment Damian is working on this issue
Plaining to update to reveal.js 3.0.0 soon... thanks for the report, I will take ASAP.

For IPython 4.0.0
When you start IPython with ipython3 notebook (and I think you have to have https://github.com/damianavila/RISE.git installed), then the cells look like this:
You have to set "Cell Toolbar" (green box) to "Slideshow". Then the toolbar highlighted in red will appear. You can try it with the button highlighted in blue.
Cell-types
I'm not too sure what the cell types mean
- -: ?
- Slide: The normal one
- Sub-Slide: vertically-aligned slides (see example)
- Fragment: will be on the same slide as the slide before
- Skip: Don't show this in the presentation. This is nice for configuration / pre-calculation
- Notes: ?
