#Exploring Entity Component Systems in Elm

Entity-Component-System (or ECS) is a pattern for designing programs that is prevalent in the games industry. This pattern consists of three simple parts:

Entity : A uniquely identifiable object that may contain any number of components
Component : A property usually representing the raw data of one aspect of the object. (Position is a component, Velocity is a component, Strength is a component, etc...)
System : A continuous process performing actions on every entity that possesses a component of the same aspect as that system

To understand this, let us try to make a simple example: Boxes that move in space:

a simple git branching model (written in 2013)

This is a very simple git workflow. It (and variants) is in use by many people. I settled on it after using it very effectively at Athena. GitHub does something similar; Zach Holman mentioned it in this talk.

Update: Woah, thanks for all the attention. Didn't expect this simple rant to get popular.

	// Usage:
	// Put this in a separate file and load it as the first module
	// (See https://github.com/jrburke/requirejs/wiki/Internal-API:-onResourceLoad)
	// Methods available after page load:
	// rtree.map()
	// - Fills out every module's map property under rtree.tree.
	// - Print out rtree.tree in the console to see their map property.
	// rtree.toUml()
	// - Prints out a UML string that can be used to generate UML
