canonical/node_modules/jscs/CHANGELOG.md

Canonical code style linter and formatter for JavaScript, SCSS and CSS.

## Version [2.6.0](https://github.com/jscs-dev/node-jscs/compare/v2.5.1...v2.6.0) (11-18-2015):

Thanks to @seanpdoyle, we're able to move some of the ES6 rules from [ember-suave](https://github.com/dockyard/ember-suave) to JSCS!

### New Rules

#### [`disallowVar`](http://jscs.info/rule/disallowVar) (Sean Doyle)

Disallows declaring variables with `var`.

`"disallowVar": true`

```js
// Valid
let foo;
const bar = 1;
```

```js
// Invalid
var baz;
```

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

#### [`requireArrayDestructuring`](http://jscs.info/rule/requireArrayDestructuring) (Sean Doyle)

Requires that variable assignment from array values are destructured.

`"requireArrayDestructuring": true`

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

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

#### [`requireEnhancedObjectLiterals`](http://jscs.info/rule/requireEnhancedObjectLiterals) (Sean Doyle)

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

`"requireEnhancedObjectLiterals": true`

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

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

#### [`requireObjectDestructuring`](http://jscs.info/rule/requireObjectDestructuring) (Sean Doyle)

Requires variable declarations from objects via destructuring

`"requireObjectDestructuring": true`

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

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

#### [`disallowSpacesInGenerator`](http://jscs.info/rule/disallowSpacesInGenerator) (Francisc Romano)

Checks the spacing around the `*` in a generator function.

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

```js
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.

```js
"requireCamelCaseOrUpperCaseIdentifiers": {
  "strict": true
}
```

```js
// 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`](http://jscs.info/rule/disallowCommaBeforeLineBreak)
  - [`requireCommaBeforeLineBreak`](http://jscs.info/rule/requireCommaBeforeLineBreak)

* `requireSpaceBeforeBinaryOperators`: report "operator =" correctly when erroring (Rob Wu)
* `requireAlignedMultilineParams`: do not throw on function without body (Oleg Gaidarenko)

### Preset Changes
* `WordPress`: add `requireBlocksOnNewLines` (Gary Jones)

## Version [2.5.1](https://github.com/jscs-dev/node-jscs/compare/v2.5.0...v2.5.1) (11-06-2015):

Just some bug fixes and an internal change before we integrate CST.

### Fixes

* `disallowUnusedParams`: ignore eval exressions (Oleg Gaidarenko)
* `Configuration`: do not try to load presets with function values (Oleg Gaidarenko)
*  `requirePaddingNewLinesAfterBlocks` - don't throw on empty block  (Oleg Gaidarenko)
* `requireSpacesInGenerator` - account for named functions (Henry Zhu)

### Internal changes

* Add `Whitespace` token in preparation for using CST (Marat Dulin)

## Version [2.5.0](https://github.com/jscs-dev/node-jscs/compare/v2.4.0...v2.5.0) (10-28-2015):

### Preset Updates

Thanks to markelog and Krinkle, the built-in wikimedia preset will be hosted at https://github.com/wikimedia/jscs-preset-wikimedia. 

The purpose of this change is so that organizations can update their preset as needed without waiting for JSCS to update to another minor version (even though we are releasing more often anyway). The plan is to not update our preset dependencies until a new minor version of JSCS.

Example:

```js
// JSCS package.json
"jscs-preset-wikimedia": "~1.0.0",
```

- Wikimedia updates their preset to to `1.1.0`
- A new user runs `npm install` with jscs and will get version `1.0.0` of the wikimedia preset
- If the user wants to update the preset themselves, they can add a direct dependency in their package.json
- Otherwise they can wait for JSCS to have a minor version update (`2.4.0` to `2.5.0`) which will update all presets.

If you would like to maintain one of the default supported presets, please let us [know](https://github.com/jscs-dev/node-jscs/issues/1811).

### New Rules

#### [`requireSpacesInGenerator`](http://jscs.info/rule/requireSpacesInGenerator) (stefania11)

Checks the spacing around the `*` in a generator function.

```js
"requireSpacesInGenerator": {
    "beforeStar": true,
    "afterStar": true
}
```

```js
// allowed
var x = function * () {};
function * a() {};
var x = async function * () {};
```

> Thanks to Stefania and Christopher for working on this rule this past Sunday during the JS Open Source workshop at the NY Javascript meetup!

### New Rule Options

#### [`requireCurlyBraces`](http://jscs.info/rule/requireCurlyBraces) (Henry Zhu)

```js
"requireCurlyBraces": {
    "allExcept": ["return", "continue", "break", ...],
    "keywords": ["if", "else", "for", "while", ... ]
}
```

```js
// allowed
if (x) return;
if (x) return 1;
if (x) continue;
if (x) break;

// still not allowed
if (x) i++;
```

#### [`requireSpaceAfterComma`](http://jscs.info/rule/requireSpaceAfterComma) add option `{ allExcept: ['trailing'] }` (Brian Dixon)

```js
// allows
var a = [{
    test: /\.jsx?$/,
    exclude: /node_modules/,
    loader: 'babel',
}];
```

### Fixes

#### Account for sparse arrays in comma spacing rules (Brian Dixon)

- [`disallowSpaceBeforeComma`](http://jscs.info/rule/disallowSpaceBeforeComma), [`disallowSpaceAfterComma`](http://jscs.info/rule/disallowSpaceAfterComma)
- [`disallowSpaceBeforeBinaryOperators`](http://jscs.info/rule/disallowSpaceBeforeBinaryOperators), [`disallowSpaceAfterBinaryOperators`](http://jscs.info/rule/disallowSpaceAfterBinaryOperators)

```js
// allowed
var x = [1, , ,2];
```

#### Configuration: correct config dir detection (Oleg Gaidarenko)

Fixes a regression with loading additional rules in a `.jscsrc`

## Version [2.4.0](https://github.com/jscs-dev/node-jscs/compare/v2.3.5...v2.4.0) (10-22-2015):

We're releasing pretty often now, right? :-)

### `Fix` option

- The `--fix` CLI flag can now be used programatically and [through](http://jscs.info/overview#fix) a `.jscsrc` config. 

> This is be useful for plugin authors (not only for jscs plugins but also for `grunt`/`gulp`/`etc...`) 

### Preset updates

- The `jquery` preset (and dependant ones like `wordpress` and `wikimedia`) is less strict, whereas `idiomatic` is now more meticulous.

### Couple new rules

* [`disallowSpaceAfterComma`](http://jscs.info/rule/disallowSpaceAfterComma) - to have an opposite rule to [`disallowSpaceBeforeComma`](http://jscs.info/rule/disallowSpaceBeforeComma):

```js
[1,2,3] // valid
[1, 2, 3] // invalid
```

* [`requireAlignedMultilineParams`](http://jscs.info/rule/requireAlignedMultilineParams) - a nice addition to our indentation rules:

```js
var test = function(one, two,
/*indent!*/  three) {
  ...
};
```

### Some new rule options

* [`requireDotNotation`](http://jscs.info/rule/requireDotNotation) now supports  fancy letters like `π` - 

```js
obj["ಠ_ಠ"] // This is wrong!
obj.ಠ_ಠ // Now you get it :-)
```

* [`maxNumberOfLines`](http://jscs.info/rule/maxNumberOfLines) can now ignore comments with the `{"allExcept": ["comments"]}` option
* [`requireObjectKeysOnNewLine`](http://jscs.info/rule/requireObjectKeysOnNewLine) can ignore object properties on the same line with `{"allExcept": ["sameLine"]}` option - 
```js
var whatDoesAnimalsSay = {
    cat: 'meow', dog: 'woof', fox: 'What does it say?' // this is cool now
};
```

### Fixes

* Account for bare blocks in both [`disallowNewlineBeforeBlockStatements`](http://jscs.info/rule/disallowNewlineBeforeBlockStatements) and [`disallowSpaceBeforeBlockStatements`](http://jscs.info/rule/disallowSpaceBeforeBlockStatements)

```js
// allows
var a = 1;

{
  let b = 1;
}
```

## Version [2.3.5](https://github.com/jscs-dev/node-jscs/compare/v2.3.4...v2.3.5) (10-19-2015):

Why not fix some more bugs!

### Bug Fixes
 * Fix: `requireSpacesInForStatement` account for parenthesizedExpression (Henry Zhu)
 
```js
// allows ()
for (var i = 0; (!reachEnd && (i < elementsToMove)); i++) {
```
 
 * Fix: `disallowCommaBeforeLineBreak`: fix for function params (Henry Zhu)
 
```js
// allows
function a(b, c) {
  console.log('');
}
```
 
 * Fix: `requirePaddingNewLineAfterVariableDeclaration` - allow exported declarations (Henry Zhu)
 
```js
// allows
export var a = 1;
export let a = 1;
export const a = 1;
```

 * Fix: `disallowSpaceAfterKeywords` - fix issue with using default keyword list (Henry Zhu)

```js
// fixes autofix from `return obj` to `returnobj`
```

 * Fix: `disallowTrailingComma`, `requireTrailingComma` - support ObjectPattern and ArrayPattern (Henry Zhu)

```js
// disallow
const { foo, bar } = baz;
const [ foo, bar ] = baz;

// require
const { foo, bar, } = baz;
const [ foo, bar, ] = baz;
```

Fix an issue with `--extract` option being true by default

## Version [2.3.1](https://github.com/jscs-dev/node-jscs/compare/v2.3.0...v2.3.1) (10-14-2015):

A bunch of bug fixes in this release!

### The Future

We are probably going to start 3.0 for the next release (mainly integrating [CST](https://github.com/cst/cst) into JSCS). If you want to know more about CST check out the [previous changelog](https://github.com/jscs-dev/node-jscs/blob/master/CHANGELOG.md#-つ-_-つ--give-cst).

Our current plan is to move our 3.0/cst branch to master and then create a 2.x branch to continue to release bug fixes / contributer PRs. The core team will be mainly focused on tackling issues on our [3.0 roadmap](https://github.com/jscs-dev/node-jscs/issues/1854) (which we are still planning). We would love to hear your feedback on what you think should be in 3.0 and beyond!

### Bug Fixes:

* [`disallowMultipleVarDecl`](http://jscs.info/rule/disallowMultipleVarDecl) - improve `{"allExcept": ["require"]}` logic (ValYouW)

```js
// Allow MemberExpressions: require('a').b.c;
var fs = require('fs');
var Emitter = require('events').EventEmitter;
```

* [`disallowSpaceAfterObjectKeys`](http://jscs.info/rule/disallowSpaceAfterObjectKeys) - Allow no space after key with `align` option. (Andrey Ermakov)


```js
// this should be allowed
var f = {
    "name": 1,
    "x": 2
};
```

* [`disallowUnusedParams`](http://jscs.info/rule/disallowUnusedParams) - correctly output unused param name (Oleg Gaidarenko)

```js
// Should output:
// Param unusedParam is not used at input
var a = function(unusedParam) {}
```

* [`requireDollarBeforejQueryAssignment`](http://jscs.info/rule/requireDollarBeforejQueryAssignment) - validate all keys (Brian Dixon)

```js
// check all keys
var x = {
  bar: 1,
  foo: $(".foo") // error here
};
```

* [`requireDollarBeforejQueryAssignment`](http://jscs.info/rule/requireDollarBeforejQueryAssignment) - Ignore array
destructuring (Simen Bekkhus)

```js
// Don't error with this
const [beep, boop] = meep;
var $s = $("#id")
```

* `CLI` - "auto-configure" argument should always be at the end
(Oleg Gaidarenko)

```bash
// correct autoconfigure args
jscs --autoconfigure ./files/here
```

*  `js-file` - make parser not confuse token types (Oleg Gaidarenko)

```js
// Fixes issues with keywords like with
class A {
  catch() {}
}
```

Again, a big thanks to everything using [JSCS](jscs.info)! Definitely continue to report any bugs and new ideas! We always appreciate any help/PRs!

We'll probably be moving more of the new rule/option issues to [`orphaned`](https://github.com/jscs-dev/node-jscs/issues?q=label%3Aorphaned+is%3Aclosed) which just means that they are on hold but anyone can still PR it or reopen it later. Remember to tweet at us at [@jscs_dev](https://twitter.com/jscs_dev) and chat with us on our [gitter room](https://gitter.im/jscs-dev/node-jscs)!

## Version [2.3.0](https://github.com/jscs-dev/node-jscs/compare/v2.2.1...v2.3.0) (10-07-2015):

A quick update! A few more rules, preset updates, and bug fixes!

> If anyone missed it from the previous minor release, we've been working on https://github.com/cst/cst. This will help us continue to autofix more complex rules in the future. If you want to know more about it check out the [changelog](https://github.com/jscs-dev/node-jscs/blob/master/CHANGELOG.md#-つ-_-つ--give-cst).

Now that we're done implementing all of ES6 the next major thing we'll be working on is intergrating CST into JSCS.

### New Rules:

#### [`disallowIdenticalDestructuringNames`](http://jscs.info/rule/disallowIdenticalDestructuringNames) (ES6) (Henry Zhu)

```js
// Valid for "disallowIdenticalDestructuringNames": true
var {left, top} = obj; // shorthand
var {left, top: topper} = obj; // different identifier
let { [key]: key } = obj; // computed property
```

```js
// Invalid for "disallowIdenticalDestructuringNames": true
var {left: left, top: top} = obj;
```

#### [`disallowNestedTernaries`](http://jscs.info/rule/disallowNestedTernaries) (Brian Dixon)

```js
// Valid for "disallowNestedTernaries": "true"
// Valid for "disallowNestedTernaries": { "maxLevel": 0 }
var foo = (a === b) ? 1 : 2;
```

```js
// Invalid for "disallowNestedTernaries": true
// Valid for "disallowNestedTernaries": { "maxLevel": 0 }
var foo = (a === b)
  ? (a === c)
    ? 1
    : 2
  : (b === c)
    ? 3
    : 4;
```


#### [`requireSpaceAfterComma`](http://jscs.info/rule/requireSpaceAfterComma) (Brian Dixon)

> To match [requireSpaceBeforeComma](http://jscs.info/rule/requireSpaceBeforeComma)

```js
// Valid for "requireSpaceAfterComma": true
var a, b;
```

```js
// Invalid for "requireSpaceAfterComma": true
var a,b;
```


### Preset Updates:

- Preset: add more comma rules to jquery and airbnb presets (Oleg Gaidarenko) [`94f175e`](https://github.com/jscs-dev/node-jscs/commit/94f175eec822f62528e6e5ca5aab0eb1de037243)
- Preset: `wordpress` - change `requireCamelCaseOrUpperCaseIdentifiers` from `true` to `ignoreProperties` [`58ba037`](https://github.com/jscs-dev/node-jscs/commit/58ba030744e8c7e55fa40a08bf19e89fc93a7eed)

### Bug Fixes:

- Fix: `disallowParenthesesAroundArrowParam` - account for non-identifiers (`RestElement`, `ArrayPattern`) correctly (Henry Zhu) [`bcfaa51`](https://github.com/jscs-dev/node-jscs/commit/bcfaa5192b09391bdec31adecab14d3861817c8a) [#1831](https://github.com/jscs-dev/node-jscs/issues/1831)
- Fix: `disallowCommaBeforeLineBreak` correctly handle empty object (Oleg Gaidarenko)
[`6571ebb`](https://github.com/jscs-dev/node-jscs/commit/6571ebbbf29e5b96be45ade585e4676de3c2817d) [#1841](https://github.com/jscs-dev/node-jscs/issues/1841)

Again, a big thanks to everything using JSCS! Definitely continue to report any bugs and new ideas! We always appreciate any help/PRs as we don't have that many resources!

### Other

 * disallowDanglingUnderscores: correct documentation (Oleg Gaidarenko)
 * Docs: `disallowMultipleVarDecl` typo (ValYouW)
 * Docs: couple small fixes (Oleg Gaidarenko)
 * Internal: `Checker` - return correct arguments for excluded files (Oleg Gaidarenko)
 * Misc: remove babelType and just use node.type (Henry Zhu)
 * Misc: Update CHANGELOG.md (Craig Klementowski)
 * Misc: Use Chai (Marat Dulin)

## Version [2.2.1](https://github.com/jscs-dev/node-jscs/compare/v2.2.0...v2.2.1) (09-29-2015):

### Bug Fix:

Quick fix related to checker not returning correctly with excluded files.

- [`f12830a`](https://github.com/jscs-dev/node-jscs/commit/f12830a469959f3543c51bfc632fe37292ea6d09) [#1816](https://github.com/jscs-dev/node-jscs/issues/1816)
    - Internal: `Checker` - return correct arguments for excluded files ([markelog](https://github.com/markelog))

## Version [2.2.0](https://github.com/jscs-dev/node-jscs/compare/v2.1.1...v2.2.0) (09-28-2015):

Again, it's been way too long since the last version; we're going to be releasing more often in the future!

In this release, we have a nicer [homepage](http://jscs.info/), 5 new rules, 4 more autofixable rules, many new rule options/bug fixes, and a [jscs-jsdoc@1.2.0](https://github.com/jscs-dev/jscs-jsdoc/blob/master/CHANGELOG.md#v120---2015-09-22) update.

We also added support for using YAML in config files, checking JS style in HTML files, and are **trying out some non-stylistic rules** (like [`disallowUnusedParams`](http://jscs.info/rule/disallowUnusedParams))!

Be on the look out for https://github.com/cst/cst (just finished ES6 support this weekend) if you haven't already.

### Autofixing: Support for 4 more rules!

Thanks to [@markelog](https://github.com/markelog), we also have autofix support for the following rules:

- [`disallowSemicolons`](http://jscs.info/rule/disallowSemicolons)
- [`requireSemicolons`](http://jscs.info/rule/requireSemicolons)
- [`disallowQuotedKeysInObjects`](http://jscs.info/rule/disallowQuotedKeysInObjects)
- [`requireCapitalizedComments`](http://jscs.info/rule/requireCapitalizedComments)

> We will also be labeling which rules don't support autofixing (only a few).

### Configuration: YAML support, and linting JS in HTML files

We weren't even thinking about different config formats, but [@ronkorving](https://github.com/ronkorving) stepped in and added support for using YAML as a config format!

So now you can use a `.jscsrc / jscs.json` (JSON) file or a `.jscs.yaml` (YAML) file.

[@lahmatiy](https://github.com/lahmatiy) has landed support for linting javascript in HTML files with the [extract](http://jscs.info/overview#extract) option! Thanks so much for sticking with us for that PR.

Example usage:
```
jscs ./hello.html --extract *.html
```

### New Rules

#### [`disallowMultiLineTernary`](http://jscs.info/rule/disallowMultiLineTernary) (Brian Dixon)

```js
// Valid for "disallowMultiLineTernary": true
var foo = (a === b) ? 1 : 2;
```

#### [`requireMultiLineTernary`](http://jscs.info/rule/requireMultiLineTernary) (Brian Dixon)

```js
// Valid for "requireMultiLineTernary": true
var foo = (a === b)
  ? 1
  : 2;
```

#### [`disallowTabs`](http://jscs.info/rule/disallowTabs) (Mike Ottum)

It disallows tab characters everywhere!

#### [`disallowUnusedParams`](http://jscs.info/rule/disallowUnusedParams) (Oleg Gaidarenko)

Another cool rule [@markelog](https://github.com/markelog) added is actually a non-stylistic rule with autofixing support! It checks to make sure you use the parameters in function declarations and function expressions!


```js
// Invalid since test is unused
function x(test) {
}
var x = function(test) {
}
```

#### [`validateCommentPosition`](http://jscs.info/rule/validateCommentPosition) (Brian Dixon)

Comments that start with keywords like `eslint, jscs, jshint` are ignored by default.

```js
/* Valid for "validateCommentPosition": { position: `above`, allExcept: [`pragma`] } */
// This is a valid comment
1 + 1; // pragma (this comment is fine)

/* Valid for "validateCommentPosition": { position: `beside` } */
1 + 1; // This is a valid comment
```

Just as a reminder, you can disable certain AST node types with the [`disallowNodeTypes`](http://jscs.info/rule/disallowNodeTypes.html) rule which takes in an array of node types.

For example: if you want to disable arrow functions for some reason, you could do

`"disallowNodeTypes": ['ArrowFunctionExpression']`.

### Presets: Idiomatic.js and other updates

We finally added support for [Idiomatic.js](https://github.com/rwaldron/idiomatic.js)! There are a few more rules we still need to add, so leave a comment in the [issue](https://github.com/jscs-dev/node-jscs/issues/1065) or create a new one.

* `Google`: remove `capitalizedNativeCase` option in the JSDoc `checkTypes` rule (Sam Thorogood)
* `Idiomatic`: add initial preset (Henry Zhu)
* `jQuery`: add `disallowSpacesInCallExpression` rule to (Oleg Gaidarenko)
* `jQuery`: use `ignoreIfInTheMiddle` value for `requireCapitalizedComments` rule (Oleg Gaidarenko)
* `jQuery`: add `validateIndentation` rule (Oleg Gaidarenko)
* `Wikimedia`: enable `es3` (James Forrester)

### Rule Options/Changes

* `requireSpacesInsideParentheses`: `ignoreParenthesizedExpression` option (Oleg Gaidarenko)
* `disallowSpaceAfterObjectKeys`: add `method` exception option (Alexander Zeilmann)
* `disallowSpaceBeforeSemicolon`: add `allExcept` option (Oleg Gaidarenko)
* `requireCapitalizedComments`: add `ignoreIfInTheMiddle` option (Oleg Gaidarenko)
* `disallowSpacesInsideParentheses`: add quotes option (Oleg Gaidarenko)
* `requireSpacesInsideParentheses`: add quotes option (Oleg Gaidarenko)
* `requireCapitalizedComments`: add default exceptions (alawatthe)
* `requireArrowFunctions`: create an error on function bind (Henry Zhu)
* Misc: Bucket all rules into groups, test case to ensure new rules have a group (indexzero)

### Bug Fixes

We fixed a bug with exit codes not matching the [wiki](https://github.com/jscs-dev/node-jscs/wiki/Exit-codes) (Oleg Gaidarenko).

* `disallowParenthesesAroundArrowParam`: fix check for params (Henry Zhu)
* `spacesInsideBrackets`: account for block comments (Oleg Gaidarenko)
* `disallowSemicolons`: ignore needed exceptions (Oleg Gaidarenko)
* `spacesInFunctionExpression`: account for async functions (MikeMac)
* `disallowSpaceBeforeSemicolon`: do not trigger error if it's first token (Oleg Gaidarenko)
* `requireCapitalizedComments`: consider edge cases (Oleg Gaidarenko)
* `requireSemicolons`: handle phantom cases (Oleg Gaidarenko)
* `spaceAfterObjectKeys`: fix for computed properties with more than one token (Henry Zhu)
* Exclude `.git` folder by default (Vladimir Starkov)

### JSDoc updates
* New Rule: [`checkParamExistence`](http://jscs.info/rule/jsDoc#checkparamexistence)
* New Rule: [`requireReturnDescription`](http://jscs.info/rule/jsDoc#requirereturndescription)
* [`enforceExistence`](http://jscs.info/rule/jsDoc#enforceexistence) add `paramless-procedures` exception

### What's JSCS?

The homepage now showcases what JSCS actually does. We were missing a :cat: picture as well so ...

### ༼ つ ◕_◕ ༽つ  GIVE CST!

We've also been busy working on https://github.com/cst/cst.

![cst](https://raw.githubusercontent.com/cst/cst/master/docs/cst-example.png)

CST stands for `Concrete Syntax Tree`, as opposed to AST which stands for `Abstract Syntax Tree`. CST uses a regular AST but adds support for information that you normally don't care about but is vital for a style checker, e.g. spaces, newlines, comments, semicolons, etc. Using a CST will allow us to support more complex autofixing such as adding curly braces while retaining other formatting or much larger transformations.

We just finished supporting all of ES6 this past weekend. [ES6+](https://github.com/cst/cst/issues/39) and [JSX](https://github.com/cst/cst/issues/3) support is also in progress! We'll be integrating CST into JSCS in the [3.0 branch](https://github.com/jscs-dev/node-jscs/tree/3.0), so look out for that soon (CST uses babel as its AST parser).

If you're interested, there was a lot of discussion on CSTs at the [ESTree](https://github.com/estree/estree/issues/41) repo.

Hopefully we can get more community help for JSCS! (check out [CONTRIBUTING.md](https://github.com/jscs-dev/node-jscs/blob/master/CONTRIBUTING.md#how-you-can-help) if you're interested)

We have a [`beginner-friendly`](https://github.com/jscs-dev/node-jscs/labels/beginner-friendly) tag for people to get started on issues.

### Small personal sidenote

Thanks to everyone who has been submitting issues/PRs!

It's been almost a year since I (hzoo) really started contributing to open source. It's still crazy to me that my first pull request was just adding the [table of contents](https://github.com/jscs-dev/node-jscs/pull/677). I was so excited to contribute that day!

Little did I know I would slowly do more and more - typo fixes, docs changes, bugfixes, rules, and then eventually become part of the team! I've become a better communicator and become more confident to give and take constructive feedback. I'm currently still figuring out how to review PRs, label issues, do changelogs (like right now), release, etc.

So much has happened after starting that one simple contribution! Even though I know a lot more about ASTs, javascript/node, and programming style, it all adds up to much more than that technical knowledge.

Contributing here helped me make PRs to a lot of other projects (in my case babel, eslint, and others). I understand more that it doesn't take a special person to start helping out. I really hope to encourage others to join our awesome open source community at large!

## Version [2.1.1](https://github.com/jscs-dev/node-jscs/compare/v2.1.0...v2.1.1)

### Overview

This release consists mostly of bug-fixes. Check them out – there are a lot of them!

We also managed to squeeze two new rules - [requireSpacesInsideParenthesizedExpression](http://jscs.info/rule/requireSpacesInsideParenthesizedExpression.html) and [disallowSpacesInsideParenthesizedExpression](http://jscs.info/rule/disallowSpacesInsideParenthesizedExpression.html), increase performance, and improve ES6 support.

#### Fix regarding global jscs installs and plugins

One of the biggest issues fixed: a **global** jscs install can finally load **local** extensions (à la gulp style) like error-filters, plugins, additional rules, and presets.

This will fix issues with using a custom preset with something like [SublimeLinter](https://packagecontrol.io/packages/SublimeLinter-jscs) which uses the global jscs install.

- To make a custom preset, you need to publish a npm package with a jscs config file
- We recommend the package name starts with `jscs-preset-` or with `jscs-config-` to help with searching for presets on npm and defining it in your config
- This would allow you to specify your preset more succinctly: `”preset”: “awesome”` instead of `”preset”: “jscs-preset-awesome”`
- You can also share multiple presets in one package with `”preset”: “awesome/super-awesome”`, provided that you have `super-awesome.{json, js}` in your package root directory
- Create a `jscs.json` file to store your jscs config
- In your `package.json`, set the `main` field to `jscs.json`

```js
// example package.json in `jscs-config-awesome`
{
  “name”: “jscs-config-awesome”,
  “version”: “1.0.0”,
  “main”: “jscs.json”
}

// example .jscsrc using a custom preset
// assuming the preset package name is `jscs-config-awesome`
{
  “preset”: “awesome”,
  “disallowEmptyBlocks”: false // example of disabling a preset rule with false
}
```

We will add more comprehensive documentation for this feature a bit later, so stay tuned.

#### Disable a rule with `false` or `null`

You can use `false` (instead of only `null`) to disable a rule (such as in a preset). This was a point of confusion for newer users. To disable a rule you can do:

```js
{
  “preset”: “airbnb”,
  “disallowEmptyBlocks”: null // disabling a rule with null
  “disallowSpacesInCallExpression”: false // disabling a rule with false
}
```

## Version [2.1.0](https://github.com/jscs-dev/node-jscs/compare/v2.0.0...v2.1.0)

### Overview
In this release, we added three more rules: two of them are ES6-only, they "protect" you
from the downside of arrow functions (see [1](http://jscs.info/rule/disallowArrowFunctions.html) and [2](http://jscs.info/rule/disallowShorthandArrowFunctions.html) for an explanation of why you might want to enable them) and another universal one if you [like](http://jscs.info/rule/validateOrderInObjectKeys.html) to keep your object neat and tidy.

Airbnb, jQuery, and Wordpress presets are now using some of the new rules we added in the previous release. Whereas, the wikimedia preset is now less strict for [JSDoc](http://jscs.info/rule/jsDoc.html) comments.

## Version [2.0.0](https://github.com/jscs-dev/node-jscs/compare/v1.13.1...v2.0.0)

### Overview

Gosh! We haven’t released a new version in more than two months! What have we done all this time?
Well, we were working hard on the next big step - 2.0!

And we’re finally ready to show it to you. We’ve improved JSCS all over the place!

### `esnext`
It was a big pain to check ES6/JSX code with JSCS, since you had to install special extensions or different parsers. Well, no more of that! Thanks to all the hard work of the @hzoo, now you can just write `"esnext": true` in your config or execute JSCS from the CLI with the `--esnext` flag.
Now all that new fancy code will be examined without any hassle, as [decorators](https://medium.com/google-developers/exploring-es7-decorators-76ecb65fb841), [function bind (::)](https://github.com/zenparsing/es-function-bind) operator, and all valid babel code can be checked by JSCS.

We also added seven ES6-only rules; see below for more information.

### Autofixing
We really want to support autofixing for as many rules as possible. But as it turns out, we are at forefront of this problem; it’s really hard to change the code without affecting unrelated instructions.

What we need is a [Concrete Syntax Tree](https://en.wikipedia.org/wiki/Parse_tree), instead of the [AST](https://en.wikipedia.org/wiki/Abstract_syntax_tree) + tokens structures that we use now. Unfortunately, there is no CST standard for JavaScript at the moment – this is why we decided to step up and come up with our vision of a CST - https://github.com/mdevils/cst. Currently, we are working with the [estree](https://github.com/estree/estree/issues/41) team on this proposal – hoping the development of this crucial part of JavaScript parsing will move faster.

Meanwhile, using some workarounds and hacks, we managed to support autofixing for 4 more rules:

* [requireTrailingComma](http://jscs.info/rule/requireTrailingComma.html)
* [disallowTrailingComma](http://jscs.info/rule/disallowTrailingComma.html)
* [disallowTrallingWhitespace](http://jscs.info/rule/disallowTrailingWhitespace.html)
* [validateQuoteMarks](http://jscs.info/rule/validateQuoteMarks.html)

### New rules
There are 31 new rules, including 16 rules for JSDoc [validation](http://jscs.info/rule/jsDoc.html), and 7 ES6-only rules:

* [requireSpaceBeforeComma](http://jscs.info/rule/requireSpaceBeforeComma.html)
Require spaces before commas
* [disallowSpaceBeforeComma](http://jscs.info/rule/disallowSpaceBeforeComma.html)
Disallow spaces before commas
* [requireVarDeclFirst](http://jscs.info/rule/requireVarDeclFirst.html)
Requires `var` declaration to be on the top of an enclosing scope
* [disallowSpaceBeforeSemicolon](http://jscs.info/rule/disallowSpaceBeforeSemicolon.html)
Disallows spaces before semicolons.
* [requireMatchingFunctionName](http://jscs.info/rule/requireMatchingFunctionName.html)
Requires function names to match member and property names.
* [disallowNodeTypes](http://jscs.info/rule/disallowNodeTypes.html)
Disallow use of certain [node types](https://github.com/jquery/esprima/blob/758196a1c5dd20c3ead6300283a1112428bc7045/esprima.js#L108-L169) (from Esprima/ESTree).
* [requireObjectKeysOnNewLine](http://jscs.info/rule/requireObjectKeysOnNewLine.html)
Requires placing object keys on new line
* [disallowObjectKeysOnNewLine](http://jscs.info/rule/disallowObjectKeysOnNewLine.html)
Disallows placing object keys on new line

#### New ES6-only rules
* [disallowParenthesesAroundArrowParam](http://jscs.info/rule/disallowParenthesesAroundArrowParam.html)
Disallows parentheses around arrow function expressions with a single parameter.
* [requireArrowFunctions](http://jscs.info/rule/requireArrowFunctions.html)
Requires that arrow functions are used instead of anonymous function expressions in callbacks.
* [requireNumericLiterals](http://jscs.info/rule/requireNumericLiterals.html)
Requires use of binary, hexadecimal, and octal literals instead of `parseInt`.
* [requireParenthesesAroundArrowParam](http://jscs.info/rule/requireParenthesesAroundArrowParam.html)
Requires parentheses around arrow function expressions with a single parameter.
* [requireShorthandArrowFunctions](http://jscs.info/rule/requireShorthandArrowFunctions.html)
Require arrow functions to use an expression body when returning a single statement
* [requireSpread](http://jscs.info/rule/requireSpread.html)
Disallows using `.apply` in favor of the spread operator
* [requireTemplateStrings](http://jscs.info/rule/requireTemplateStrings.html)
Requires the use of template strings instead of string concatenation.

There are also a lot of new rule values (see the ["Changelog"](#changelog) section) which makes a lot of rules more flexible.

We also added new rules and values to some presets. If you feel that we’ve missed something, don't be quiet! Send us a PR and we will surely add the needed rules to your favorite preset.

### Simplified inclusion of plugins, presets, and custom rules
Since every possible JSCS extension can now be loaded without defining its full path, it is enough to just specify the needed dependency to your project so it can be found by JSCS.

```js
{
  "plugins": ["./your-local-package"], // Same with `additionalRules` and `preset` options
  "plugins": ["jscs-your-npm-package"],
  "plugins": ["your-npm-package"], // can omit “jscs-” prefix if you want
}
```

### Other
* Support for disabling rules on a [single line](http://jscs.info/overview.html#disabling-specific-rules-for-a-single-line) -
```js
if (x) y(); // jscs:ignore requireCurlyBraces
if (z) a(); // will show the error with `requireCurlyBraces`
```

* Two new reporters - `summary` (could be very helpful to acquire full overview of all possible errors in your project) and `unix`. You could enable them by providing [`--reporter=<reporter name>`](http://jscs.info/overview.html#-reporter-r) flag.

* `node_modules` path is included by default to [`excludeFiles`](http://jscs.info/overview.html#excludefiles)

* For every possible error, like missing or corrupted config, JSCS now provides [different](https://github.com/jscs-dev/node-jscs/wiki/Exit-codes) exit-codes. We believe it might be useful for piping, editors plugins, etc.

* JSCS (like any good unix program) now obeys the [rule of silence](http://www.linfo.org/rule_of_silence.html).

And of course, a lot of bug-fixes, improved ES6 support of existing rules, docs, infrastructure changes, etc.

Although this is major version, we didn't remove deprecated rule values or changed config format, we expecting to do this in the 3.0 version while switching to CST and fully refactor JSCS code-base.
