# 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.
