Tslint: key-spacing

[jamiewinder]

Unless I'm missing something, there is no way to enforce whitespace after a property key in an object literal:

    const b = {
        a : 1, // bad
        b: 2 // good
    };

I think this is covered in ESLint by key-spacing

This would be best as an enhancement to the whitespace rule. We should probably update that rule to mirror how typedef-whitespace works since #971.

Looking forward

This is pretty old, and a strange feature since we already have a rule disallowing trailing whitespace. Going to close, feel free to re-open/make a new issue if you disagree.

@johnwiseheart, how can the rule requested by @jamiewinder be enforced with currently available rules?

[xemlock]

@adanski @jamiewinder Looks like this cannot be done by the built-in rules alone. whitespace.check-type checks only for space after colon, and typedef-whitespace, although more configurable, works only for type definitions.

So I wrote whitespace-before-colon rule which complements those rules, and which checks spaces before colons in object literals and destructuring assignments.

I'd like to have this feature. @xemlock's solution was declined, but any progress on @adidahiya's proposed solution?

[adidahiya]

@NoBrainer See #4534, at this point basically all formatting-related features/enhancements will be declined.
