Function generator: error in yield statement

[zdychacek]

Hi,

I am getting an error in yield statement 'Error: expected an assignment or function call' message in following code:

function *g (): Iterable<number> {
    for (let i: number = 0; i < 100; i++) {
        yield i;
    }
}

Is there really any error in my code?

Thanks for your reply,

O.

This looks like an error reported by the compiler rather than TSLint... can you post your full stack trace or console output?

A problem on the TSLint side might be that we target ES5 instead of ES6. I think generators only work in ES6.

When I run tslint main.ts I get following main.ts[3, 3]: expected an assignment or function call, so I think this issue has something to do with TSLint.

I am targetting ES6.

Here is my tsconfig.json:

{
  "compilerOptions": {
    "module": "commonjs",
    "noImplicitAny": true,
    "target": "es6",
    "experimentalDecorators": true
  }
}

Hope this information helps somehow.

Thanks,

O.

@zdychacek Sorry, I didn't mean that you need to be targeting ES6; I meant that TSLint ought to have an option that makes it target ES6 when analyzing your code. I don't know if that's the issue for sure though. Definitely a bug either way, thanks for reporting it!

[jkillian]

Seems like we can handle this better even when internally targeting ES5, see the above PR. Should be in a release sometime soon

[zdychacek]

Great, thank you!

the fix will be released in v2.5.2. until then, I think you can avoid the issue with /* tslint:disable */ flags?
