Drag this to the bookmarks bar: RISE 5.7.1/reveal.js 5.2.1
This gives you a button to add the RISE functionality to a Jupyter notebook, either a v6 notebook or an nbclassic one. It starts from the v5.7.1 pip package and combines the necessary code into one huge (500 KB) bookmarklet. Depending on your browser, it may or may not be possible to have a bookmarklet of this size.
This version does not use the reveal.js files that were included in the pip package, it uses the files from reveal.js 5.2.1 as much as possible.
A further modifcation was made: if the first line in a code cell is
#hidden_inputthen the input part of the cell will not be shown on the slides, only the output part.
The code for this can be found at codeberg.org/j0r1/rise_bookmarklet.
