Rich-Harris / CSV Parser

Created October 11, 2012 17:15

A bog standard JavaScript CSV parser. Putting it here so I don't need to keep rewriting it or remembering where I put the last one. Usage self-explanatory, will break if you throw weird shit at it (cells with newlines in them, that sort of thing)

	CSVParser = function ( options ) {
	var defaults, delimiter, rowDelimiter, qualifier, qualified, unqualified;

	options = options \|\| {};

	defaults = {
	delimiter: ',',
	rowDelimiter: '\n',
	qualifier: '"'
	};

Rich-Harris / addCommaSeparators.js

Created June 11, 2013 12:05

Add comma separators (e.g. `addCommaSeparators(1234567) === '1,234,567'`)

	(function ( global ) {

	'use strict';

	var addCommaSeparators = function ( num, precision ) {
	var integer, decimal, remaining, result, lastThree;

	integer = Math.floor( num );
	decimal = num - integer;

Rich-Harris / Player.js

Last active December 18, 2015 17:09

A solution to the problem posed by Mike Pennisi on http://weblog.bocoup.com/info-hiding-in-js/ - per-instance private variables and methods that don't forgo the benefits of prototypal inheritance or rely on obscurity (or ES6)

	var Player = (function () {

	var Player, generateGuid, maxCoins, secrets, get, set, cashIn;

	maxCoins = 100;

	// via http://stackoverflow.com/questions/105034/how-to-create-a-guid-uuid-in-javascript
	generateGuid = function () {
	return 'xxxxxxxx-xxxx-4xxx-yxxx-xxxxxxxxxxxx'.replace(/[xy]/g, function(c) {
	var r, v;

Rich-Harris / linearScale.js

Last active May 4, 2016 19:57

A simple linear scale function generator, similar to D3's

	(function ( global ) {

	'use strict';

	var linearScale = function ( domain, range ) {
	var d0 = domain[0], r0 = range[0], multiplier = ( range[1] - r0 ) / ( domain[1] - d0 );

	// special case
	if ( r0 === range[1] ) {
	return function () {

Rich-Harris / reindex.js

	// addEventListener polyfill IE6+
	if ( !window.addEventListener ) {
	(function ( win, doc ) {

	var property, instance = this;

	for ( property in e ) {
	instance[ property ] = e[ property ];

Rich-Harris / thresholdScale.js

Created July 21, 2013 17:03

Threshold scale generator, similar to D3's

	(function ( global ) {

	'use strict';

	// Threshold scale generator, similar to D3's
	// Usage:
	//
	// scale = thresholdScale([ 0, 20, 40, 100 ], [ 'red', 'green', 'blue' ]);
	// scale( 10 ) -> 'red'
