Async/await support

[erikdung]

Hi, is it possible to add acorn-es7-plugin to parse async/await function? Thanks

Yes, you can use them both (that's why they're plugins in the first place). But it doesn't require anything special on acorn-jsx side.

Also, async/await are natively supported by Acorn without any plugins now, so you just need to set ecmaVersion correctly.

I have the script:

export function configure(trackpoint, feeds, auth, platform) {
    return async function (dispatch) {
        try {
            const response = await put("/api/feed-checker/shop-config", {
                trackpoint,
                feeds,
                platform,
                auth: auth && auth.password && auth.username ? auth : null
            })
            if (response.body.status === 'ok') {
                dispatch(configureSuccess())
                success('Konfigurace byla úspěšně uložena.')
            }
            else {
                const errors = response.body.errors.reduce((sum, error) => {
                    sum[feedMapping[error[0]]] = error[1]
                    return sum
                }, {})
                dispatch(stopAsyncValidation(platform === 'shoptet' ? 'feedForm' : 'feedForm2', errors))
            }
        } catch (error) {
            console.log(error)
            dispatch(configureError(error))
        }
    }
}

I got the error: SyntaxError: Unexpected token i point to line start with async. I also tried set ecmaVersion: 7 without success.

Oh right, sorry - you confused me with acorn-es7-plugin. async/await is in fact ES2017 (ES8), so you need to set ecmaVersion to either 2017 or 8.

[erikdung]

I have tried both, 2017 & 8, but the same SyntaxError appeared.

Certainly doesn't fail here: http://astexplorer.net/#/gist/899c54bf6d2f2d0cf6f02d0d5098338e/e408ffcd33b233e2f7f3ff50f99bf8612bcbbc4d

Make sure you're using latest version of Acorn or something.
