Add the rule disallowPaddingNewLinesBeforeUseStrict

[nikini]

It's nice that we have the option dissallowPaddingNewLinesAfterUseStrict and requirePaddingNewLinesAfterUseStrict but it would be nice if we could have the same thing for the before the use strict,

The following rules could be added:

disallowPaddingNewLinesBeforeUseStrict

Valid:

(function () {
    'use strict';

    // Code goes here
}());

Invalid:

(function () {

    'use strict';

    // Code goes here
}());

requirePaddingNewLinesBeforeUseStrict

Valid:

(function () {

    'use strict';

    // Code goes here
}());

Invalid:

(function () {
    'use strict';

    // Code goes here
}());

Their values would be either true or false. (Keeping it simple)

Would you like to implement it?

[nikini]

Hmm, sure, but it would take a while since I'm going on vacation tomorrow for 10 days :)

Hey, happy vacation! :)

We released 3.0 recently! We also wrote a post about how 3.0 will be our last major release (since we are deprecating the project) and that we are merging with ESLint!

Thus we won't be working on any new features moving forward which includes new rules/options. We will continue to fix bugs and work on CST/better autofixing for current rules in the upcoming months both to help JSCS users and to gain experience that we can hopefully use in ESLint. But otherwise we both teams will be working on getting ESLint feature parity with JSCS and just a nice transition for our users.

I'm putting an orphaned label to note this issue isn't planned to be worked on, but might be a good contribution as a custom rule (not in JSCS core itself).

I would encourage anyone who wants the rule to try writing it themselves: I would either write a custom rule or submit an issue to ESLint and if accepted a PR. Otherwise a custom rule that won't be in core repo itself.

JSCS rules are also very similar to ESLint rules: here are some resources to get started:

• Project-specific Lint Rules with ESLint
• Creating Custom Rules for ESLint
• Maintaining JavaScript Code Quality with ESLint
