Created January 22, 2025 03:36

Python code to generate tables of every set class (OPTC-equivalent) sorted by distance to the perfectly even C-note chord

	# run this with python3

	# See https://harmoniousapp.net/p/71/Set-Classes for more info

	import math

	# Utility functions for dealing with Set Classes
	# a number in binary between 0 and 111111111111b (4093 decimal) can be converted
	# to and from a list of integers, such as [0,4,7] which is 000010010001b or 145 decimal

Hacks to react-native-svg ./src/elements/Path.tsx to fix a bug where <path> elements are not ignoring passed-in x and y attributes, and translating paths off canvas, and thus not rendering some paths. Using withoutXY instead of extract fixes this. Hack to extractFill.ts to allow fill:none to work as expected. Hacks to RNSVGRenderable.m init meth…

	import React from 'react';
	import { withoutXY } from '../lib/extract/extractProps';
	import Shape from './Shape';
	import { RNSVGPath } from './NativeComponents';

	export default class Path extends Shape<{
	d?: string;
	}> {
	static displayName = 'Path';

Find the intersections (two points) of two circles, if they intersect at all

	// based on the math here:
	// http://math.stackexchange.com/a/1367732

	// x1,y1 is the center of the first circle, with radius r1
	// x2,y2 is the center of the second ricle, with radius r2
	function intersectTwoCircles(x1,y1,r1, x2,y2,r2) {
	var centerdx = x1 - x2;
	var centerdy = y1 - y2;
	var R = Math.sqrt(centerdx * centerdx + centerdy * centerdy);
	if (!(Math.abs(r1 - r2) <= R && R <= r1 + r2)) { // no intersection
