RFE: Braces should be opened on newline whenever possible

[cowwoc]

Please add a rule that requires opening braces on new line, whenever possible. For example:

function good()
{
  // body goes here
}

instead of:

function bad() {
  // body goes here
}

The only case I'm aware of where this is disallowed is for returning anonymous objects:

return {
  "key": value
}

I would accept a proper pull-request on this.

I would like the opposite to be enforced by an option.

[timmywil]

But only for statements. For instance, I'd like to differentiate between

var o = {
  key: [{
    a: 0
  },
  // okay
  {
    a: 1
  }]
};

and

// good
if (true) {
}
// bad
if (true)
{
}

By statements, I mean, if, else, for, while, switch, do, return, try, catch, and function. Elsewhere is fine.

Perhaps the exception could be narrowed down to whenever the curly is preceded by comma and optional whitespace.

@timmywil you mean all blockStatements and not objectExpressions, right?

This would be similar to *SpaceBeforeBlockStatements and be called *NewlineBeforeBlockStatements. Sound good?

[timmywil]

@mikesherov Yes, thank you for putting it concisely. Sounds great.

[bhardin]

I agree with @timmywil, I'd like to have a rule to enforce the opposite also. Was NewlineBeforeBlockStatements ever implemented?

[cowwoc]

@bhardin yes, but it has yet to be merged. See #536
