A console notebook player

Ths is a console/terminal program for running a Jupyter notebook.

You start it up by specifying a notebook file:

$ nbplayer conx-notebooks/MNIST.ipynb nbplayer 0.0.0: type `help` or `?` to see commands

The first cell of the notebook will show in the In[0] area, followed by the nbplayer prompt:

Viewing: conx-notebooks/MNIST.ipynb -------------------------------------------------------- In [0]: | # The MNIST Dataset | | In this notebook, we will create a neural network to recognize handwritt | | We will experiment with two different networks for this task. The first | | Let's begin by reading in the MNIST dataset and printing a short descrip  MNIST.ipynb [0/84] > 

The prompt is composed of the name of the notebook, and the current cell/total cells.

If you press enter, then you will execute that cell (if it is code) and then go to the next cell.

In [1]: >>> import conx as cx MNIST.ipynb [1/84] > 

At the prompt, you can enter any of the following:

• kernal language expressions or statements
• empty line - execute current cell and advance
• n - goto next cell (skip this cell)
• p - goto previous cell
• NUMBER - goto cell #
• +AMOUNT - goto cell ahead, relative movement
• -AMOUNT - goto cell previous, relative movement
• --POSITION - from end
• ! shell command - execute command at the operating system (client side)
• q or ^d - quit nbplayer

Possible future options:

• re search forward/reverse for cell with next match
• run all code cells up to here
• i - insert cell
• d - delete cell
• u - undo operation in stack
• r - redo operation in stack
• code - show only code (toggles on/off)
