# Some Jupyter Notebooks and other material.
All of the notebooks are also available as HTML and Markdown files (generated using nbconvert) so you can view them without running Jupyter.

This starts it using the `virtualenv` version of Python so `joy` will be available. Navigate to the `joypy/docs` directory and the notebooks should be able to import the `notebook_preamble.py` file.

I find I have to include `--ip=0.0.0.0` to workaround a bug where it tries to bind to an IPv6 address, YMMV.

## Table of Contents
- 1. Basic Use of Joy in a Notebook
- 2. Library Examples - Short examples of each word in the dictionary. Various formats.
- 3. Developing a Program - Working with the first problem from Project Euler, "Find the sum of all the multiples of 3 or 5 below 1000", several forms of the program are derived.
- 4. Replacing Functions in the Dictionary - Shows the basics of defining new "primitive" functions in Python or as definitions and adding them to the dictionary.
- Factorial Function and Paramorphisms - A basic pattern of recursive control-flow.
- Generator Programs - Using the x combinator to make generator programs which can be used to create unbounded streams of values.
- Hylo-, Ana-, Cata-morphisms - Some basic patterns of recursive control-flow structures.

- Quadratic - Not-so-annoying Quadratic Formula.
- Trees - Ordered Binary Trees in Joy and more recursion.
- Zipper - A preliminary examination of the idea of data-structure "zippers" for traversing datastructures.
- notebook_preamble.py - Imported into notebooks to simplify the preamble code.
- pe1.py pe1.txt - Set up and execute a Joy program for the first problem from Project Euler. The pe1.txt file is the trace. It's 2.8M uncompressed. Compressed with gzip it becomes just 0.12M.
- repl.py - Run this script to start a REPL. Useful for e.g. running Joy code in a debugger.
