Intro

var animating = false;

// Define an animator consisting of optional incoming and outgoing animations. 
// alwaysAnimate is false unless specified as true: false means an incoming animation will only trigger if an outgoing animation is also in progress.
// forcing dontClone to true means the outward animation will use the original element rather than a clone. This could improve performance by recycling elements, but can lead to trouble: clones have the advantage of being stripped of all event listeners.
function animator( incoming, outgoing, alwaysAnimate, dontClone ){
	// The resulting animator can be applied to any number of components
	return function animate( x, y, z ){
		var config;
		var parent;

Usage

sed -E -f solver.sed input where input is a file containing the maze.

For best results, resize your terminal to match the height of the maze. To disable animations, delete the lines containing p.

Maze format

The solver assumes the following:

• The maze only contains the characters # \nSE
• Every line has the same number of characters
• There is only one start (S) and end (E)
