presentation-cell

Hides all but the currently active cell, for presentations.

Prerequisites

  • JupyterLab
  • nodejs

Installation

  1. Be sure the prerequisites are installed (conda install jupyterlab -c conda-forge nodejs)
  2. git-clone this theme (git clone https://github.com/jpivarski/JupyterLab-presentation-cell.git)
  3. cd JupyterLab-presentation-cell
  4. jlpm install
  5. jupyter labextension install .

Use

  1. Go to your presentation repo, start JupyterLab, open a notebook
  2. from the Settings → JupyterLab Theme menu, pick "presentation-cell"
  3. click on the cell to be sure it's activated; J and K walk forward and back, ctrl-enter evaluates a cell without moving to the next (very important!)
  4. write a talk/interactive demo in such a way that you don't need more than one cell on the screen at a time
  5. I usually do it at 200% magnification, with the top-menu hidden (ctrl-shift-D).
  6. you kinda have to open a notebook in the normal theme, then switch to "presentation-cell" for some obscure CSS reason; I've gotten used to it.
