Version 2.10.0 (2016-02-15):

Happy Presidents Day!

In this release, it's just some additional rules to update to the airbnb preset, new rules, and fixes.

Preset Changes

• Add maximumLineLength to the airbnb preset (reference) (Oleg Gaidarenko)
• Add disallowSpacesInsideTemplateStringPlaceholders to the airbnb preset (not explicit but used in examples) (Oleg Gaidarenko)
• Add disallowNewlineBeforeBlockStatements rule to the mdcs preset (reference) (Mauricio Massaia)

New Rules

disallowSpacesInsideTemplateStringPlaceholders

(ikokostya)

Disallows spaces before and after curly brace inside template string placeholders.

// usage in config
"disallowSpacesInsideTemplateStringPlaceholders": true

// Valid
`Hello ${name}!`

// Invalid
`Hello ${ name}!`
`Hello ${name }!`
`Hello ${ name }!`

requireImportsAlphabetized (Ray Hammond)

Requires imports to be alphabetized

// usage in config
"requireImportAlphabetized": true

// Valid
import a from 'a';
import c from 'c';
import z from 'z';

// Invalid
import a from 'a';
import z from 'z';
import c from 'c';

Rule Updates

• requireSpaceBeforeKeywords: add a allExcept option for filtering out default keywords (gpiress)
  • This allows you do specify exceptions to the all keywords instead of creating an array of whitelisted keywords when you only want to blacklist a few.

Bug fixes

• requireNumericLiterals: miss if first argument is an Identifier (Robert Jackson)
• disallowSpacesInsideTemplateStringPlaceholders: skip the edge case (Oleg Gaidarenko)
• requirePaddingNewLinesBeforeExport: exclude if only statement in block (Brian Schemp)
• maximumLineLength: some nodes might contain null values (Oleg Gaidarenko)

Docs

• Correct date in the changelog (Oleg Gaidarenko)
• Various rule corrections (Christopher Cook)

Version 2.9.0 (2016-01-23):

Changed the changelog date format to be YYYY-MM-DD.

Whoo a release during this blizzard! Hopefully, this will be our last release before we start pushing out pre-release versions of 3.0. (If necessary, we can push bug fixes to 2.x)

The plan:

• Push the 2.9.0 release
• Create a 2.x branch off of master
• Switch master to be the 3.0 branch
• Merge in 2.x changes + cleanup stuff for a 3.0 alpha release.
• Do what we can in our 3.0 milestone. We would really appreciate any help!
  • Especially for deprecating rules/options, rule merging, renames/inconsistencies that we don't catch.

New Rules

Version 2.8.0

Happy new year! Small changes this time, small, but important fixes which still warrants the minor bump.

Aside from bug fixes, this update includes improvement for the airbnb preset and allExcept option for the disallowNewlineBeforeBlockStatements

Version 2.7.0

It's this time of the year again, 2.7 is here!

One new rule, cool amount of fixes and massive jsdoc rule set update.

New Rules

Although there's only one new rule in this release, it's pretty powerful! Say thanks to @ficristo!

Version 2.6.0 (11-18-2015):

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

New Rules

Version 2.5.1 (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 (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:

// 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.

New Rules

Version 2.4.0 (10-22-2015):

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

Fix option

• The --fix CLI flag can now be used programatically and through 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 - to have an opposite rule to disallowSpaceBeforeComma:

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

• requireAlignedMultilineParams - a nice addition to our indentation rules:

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

Some new rule options

• requireDotNotation now supports fancy letters like π -

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

• maxNumberOfLines can now ignore comments with the {"allExcept": ["comments"]} option
• requireObjectKeysOnNewLine can ignore object properties on the same line with {"allExcept": ["sameLine"]} option -

var whatDoesAnimalsSay = {
    cat: 'meow', dog: 'woof', fox: 'What does it say?' // this is cool now
};

Fixes

• Account for bare blocks in both disallowNewlineBeforeBlockStatements and disallowSpaceBeforeBlockStatements

// allows
var a = 1;

{
  let b = 1;
}

Version 2.3.5 (10-19-2015):

Why not fix some more bugs!

Bug fixes

• Fix: requireSpacesInForStatement account for parenthesizedExpression (Henry Zhu)

// allows ()
for (var i = 0; (!reachEnd && (i < elementsToMove)); i++) {

• Fix: disallowCommaBeforeLineBreak: fix for function params (Henry Zhu)

// allows
function a(b, c) {
  console.log('');
}

• Fix: requirePaddingNewLineAfterVariableDeclaration - allow exported declarations (Henry Zhu)

// allows
export var a = 1;
export let a = 1;
export const a = 1;

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

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

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

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

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