No break or return statement found in case

[notslang]

function foobar() {
  switch (y) {
    case "one":
      if (x == 'foo') {
        return 'bar';
      } else {
        return 'foo';
      }
  }
}

function foobar() {
  switch (y) {
    case "one":
      throw new Error();
  }
}

Both of these examples fail because it doesn't detect the return in the if statement, or the throw that would end the function.

This pattern may seem kinda weird/contrived, but it's actually used in real code: https://github.com/pouchdb/GQL/blob/0b8d892d4922df56b301951402d614b9311250e5/pouchdb.gql.js#L635

I don't think it's contrived at all, I've ran into it myself.

It doesn't detect a break even if it isn't in an if statement. For example, the following gives an 'unexpected indentation' error:

function foo (data) {
  var i = 9;
  switch (data) {
    case 'foo':
      i = 99;
      break
    case 'bar':
      break;
  };
  while (i > 0) {
    i--
  };
};

empy case produces empty when.

And when I convert from coffee to JS, even if I put empty ; inside of when, it gives back the funny code without break statement.

when 'bar'
  ;

↓

case 'bar':

I too receive the same:

I'm guessing this won't get fixed as this has been an issue for over a year, no response has been given, and the last release was in July of 2015.

@tgaeta what editor is that?

I am getting the same problem

https://github.com/opal/opal/blob/acba5f18fb45e1c226c015abbe2cb99a26121bf6/opal/corelib/kernel.rb#L342 this code is failing on the conversion

@tgaeta what editor is that?

It is the js2.coffee website

This problem is frustrating, is there any way I could get around this?
