Add support for ES6 features

[jampy]

Currently webpack seems to fail parsing JavaScript code that contains ES6 syntax like generators.

Module parse failed: ..../main.js Line 20: Unexpected token *
You may need an appropriate loader to handle this file type.
| }
| 
| function * ex_test() {
|   throw new Error("work!");
| }

Could you please adjust the static code analysis so that it doesn't break with code that uses generators?

I'm trying to use generators natively in browsers that support them, so don't want to use a transpiler in this case..

We can do this once esprima 2.0 is published...

esprima-fb package can be used instead as it provides es6 features and is robust (used by Facebook for JSX toolchain).

[syranide]

@andreypopp Aren't all the non-JSX features of esprima-fb part of the esprima harmony branch?

👍 I'd like to use ES6 output too.

Esprima 2 is now available and Webpack tests pass with 2.1.0.

This should work in the webpack-2 branch

@pornel webpack-2 is using acorn.

Any news on this ? Is there a way to hack it to let webpack just pass through es6 code, and let the developer the responsibility to send supported code to wherever ?

Hi, has anyone found a solution/workaround?
Cheers

You can use the webpack-2 branch. It is using a ES6 parser (acorn) and understands import export and System.import.

@sokra I experimented with bumping the dependencies (package.json) to Esprima 2.5, ran npm test and so far nothing breaks the tests. This is the easiest to allow webpack to consume ES6 code.
Is this something that is desireable? If yes, I can create a PR.

I've bumped it for 1.12... Let's see how this works out.

1.12 is working for my project (babel blacklist regenerator), and tests passed, though very low coverage. Maybe this can be closed, if no need for further confirmations.
