It would be helpful if custom formatters could handle a returned Promise

It would be quite helpful if custom formatters registered with registerCustomFormat could handle a returned Promise, in particular for the toFile method.

The practical use-case here is running prettier.format (async-only) on contents being written to ensure they conform to a project's code style.

I realize Decap does not support async toFile methods.

The footprint of this change appears to be quite small though, since there are only two calls to formatEntryFile and both are in the context of async functions.

Sure, it’s probably not a big deal.

That's awesome, thanks!

Shipped v0.46.0 with the async support.

I’ve just found this Decap issue. It’s closed but Decap doesn’t support async methods as you said. It’s perhaps closed by accident or as wontfix (because ES6 promise support is relatively new), and I’ve “effectively solved” the very old issue. 🙃

Haha, nice! 9 years old!

Impressive that you're able to knock these out so quickly — a real testament to how much the frontend frameworks have evolved, and your solid code of course.
