Dart2JS and Enumerators

Question

I'm using enumerators (experimental) in my project. Pub Build (Generate JS) in my Dart Editor does not work due to the enums. In my console, this command:

dart2js file.dart --enable-enum

does work, but it is inconvinient to do it through the console. Is there any way to add arguments to the default command in Dart Editor (--enable-enums) so it'd allow it to compile into JS?

Running it by default in Dartium works and when copying and pasting the server url (http://localhost:8080/index.html), the dart2js is triggered and it starts working (after average compilation time).

EDIT: Yes, I have enums enabled in my editor.

EDIT2: To enable enums in dart2js, I have this transformer in pubspec.yaml:

transformers:
- $dart2js:
    commandLineOptions: [--enable-enum]

However, I get this error in a file, which uses enums:

Directive not allowed here.
part of thing;
^^^^^^^^^^^^^^^^
[Info from Dart2JS]:

It's weird that it works in the console with the same arguments and not in the editor.

I have filled a bug report here.

Is your enum defined in a `part` file? Is `dart2js` the last transformer in your `pubspec.yaml` transformer section? — Günter Zöchbauer, Jan 02 '15 at 11:33
Yes. The enum is defined in a part, but dart2js transformer is the only one, is it's the last one. — Vilda, Jan 02 '15 at 11:35
Why are you using `--enable-enums` (plural) on command line and `--enable-enum` (singular) in the pubspec.yaml transformer config. I think it should be the same (singular on both) https://code.google.com/p/dart/issues/detail?id=21823#c3 — Günter Zöchbauer, Jan 02 '15 at 11:38
The command line argument has a typo. Sorry. Singular should be correct AFAIK. — Vilda, Jan 02 '15 at 11:40
Have you tried to declare the enum in a library instead of a part? If this works I guess it is a bug with `part`. — Günter Zöchbauer, Jan 02 '15 at 11:42
Please post the link here if you file a bug report at dartbug.com. — Günter Zöchbauer, Jan 02 '15 at 11:59

As of 2016, the enumerators are fully implemented.
