Style Guide

Style Guide

We ask that developers respect the following guidelines when contributing pull requests to Enyo.

Indentation

The Enyo source code uses leading tabs for indentation of code.

Blocks

First curly brace at end of line, final curly brace on a line by itself:

for (var i=0; i<100; i++) { // first curly brace at end of line
    ...
} // final curly brace on a line by itself

Always use curly braces:

// bad
if (x) foo(); 

// good
if (x) {
    foo();
}

Else clauses have the else keyword between the braces:

if (x) {
    ...
} else if (y) {
    ...
} else {
    ...
}

Punctuation

We use a like-English rule whenever possible. For example, no spaces on the inside of associations, and one space after a colon:

var x = (x + 7) * 3;
var y = {neft: "zap"};
var z = [1, 2, 3, (4 + 5)];

Single space after any keyword, except function:

for (var i=0; i<100; i++) {
	...
}

while (x = 3) {
	... 
}

x = function() {
	...
}
