##Object Merger

Recurcively merges two objects.

merge(
  {foo:"foo"},
  {bar:{lol:"lol"}}

);

converts canvas image data to a 2d array of booleans

array=img2array(imagedata,width,height)

array[x][y] //gives true or false

very useful for games where you need pixel perfect collision.

Reading an image every time you check for collision is slow. Using a 2d array makes it much faster, and has a very simple syntax (array[x][y]) .

A minimalist masonry function

mason(containerElement,brickElement,brickWidth,brickHeight)

Only works with one size of brick.

The only advantage of using this over using inline-block elements is that you can use css transitions.

This function loops through all images on the page, and serves the appropriately sized image file from a list in a data attribute.

example html:

<img src="default.png" data-widths="400,600,800,1023" data-srcsuffix="-foo.png">

example javascript:

recursively checks every parent of the element to get the ABSOLUTE offset of the element.

call it like this:

getOff(element).x

getOff(element).y

a neat function that allows this:

document.getElementsByTagName('i').innerHTML="pie";

and it will change the innerHTML of all tags AUTOMATICALLY!!!!

incredible!

#Javascript Rss Reader#

Takes a rss feed and prints html (defined by a template) for every post.

Turns indentation into {curly brackets} Great for a yml to json converter or something. Credit to @maettig for writing all* the code.

Turn this:

if(3==3)
    alert("obviously!")
    alert("lol!")

Into:

	//visual basics code from http://www.vb-helper.com/howto_net_circle_circle_tangents.html ported to glsl


	vec4 FindCircleCircleIntersections(vec2 p0, float r0, vec2 p1, float r1){

	vec2 dd = p1-p0;
	float d = length(dd);

	float a = (r0 * r0 - r1 * r1 + d * d) / (2.0 * d);
	float h = sqrt(r0 * r0 - a * a);

	//function

	calendar = function(year,month,template,rowStart,rowEnd,cellStart,cellEnd){

	var tmpl=function(a,b){return a.replace(/\{\{([^{}]+)}}/g,function(c,d){return typeof b[d]=="function"?b[d]():b[d]})}

	return tmpl(template,{
	monthName:"January,February,March,April,May,June,July,August,September,October,November,December".split(",")[month],
	year:year,
	days:function(f,txt,i){
