v2.6.0

Version 2.6.0 (11-18-2015):

Thanks to @seanpdoyle, we're able to move some of the ES6 rules from the ember-suave preset to JSCS!

New Rules

disallowVar (Sean Doyle)

Disallows declaring variables with var.

"disallowVar": true

// Valid
let foo;
const bar = 1;

// Invalid
var baz;

You can also use "disallowKeywords": ["var"]

requireArrayDestructuring (Sean Doyle)

Requires that variable assignment from array values are destructured.

"requireArrayDestructuring": true

// Valid
var colors = ['red', 'green', 'blue'];
var [ red ] = colors;

// Invalid
var colors = ['red', 'green', 'blue'];
var red = colors[0];

requireEnhancedObjectLiterals (Sean Doyle)

Requires declaring objects via ES6 enhanced object literals (shorthand versions of properties)

"requireEnhancedObjectLiterals": true

var obj = {
  foo() { },
  bar
};

var obj = {
  foo: function() { },
  bar: bar
};

requireObjectDestructuring (Sean Doyle)

Requires variable declarations from objects via destructuring

"requireObjectDestructuring": true

// Valid
var { foo } = SomeThing;
var { bar } = SomeThing.foo;

// Invalid
var foo = SomeThing.foo;
var bar = SomeThing.foo.bar;

disallowSpacesInGenerator (Francisc Romano)

Checks the spacing around the * in a generator function.

"disallowSpacesInGenerator": {
    "beforeStar": true,
    "afterStar": true
}

var x = function*() {};
function*a() {};
var x = async function*() {};

New Rule Options

• requireCamelCaseOrUpperCaseIdentifiers: add strict option (Jan-Pieter Zoutewelle)

Also forces the first character to not be capitalized.

"requireCamelCaseOrUpperCaseIdentifiers": {
  "strict": true
}

// Valid
var camelCase = 0;
var UPPER_CASE = 4;

// Invalid
var Mixed_case = 2;
var Snake_case = { snake_case: 6 };
var snake_case = { SnakeCase: 6 };

• disallowSpace(After|Before)Comma: add allExcept: ['sparseArrays'] (Brian Dixon)
• validateQuoteMarks: add "ignoreJSX" value (Oleg Gaidarenko)
• requireMatchingFunctionName: add includeModuleExports option (George Chung)

Fixes

• Account for sparse arrays in rules with spacing and commas (Brian Dixon)
  • disallowCommaBeforeLineBreak
  • requireCommaBeforeLineBreak
• requireSpaceBeforeBinaryOperators: report "operator =" correctly when erroring (Rob Wu)
• requireAlignedMultilineParams: do not throw on function without body (Oleg Gaidarenko)
