Support top-level await in console

[roblourens]

microsoft/vscode#38316

Need to detect when the console input starts with await, wrap in an async IIFE, and set awaitPromise on Runtime.evaluate to true.

I'm not sure what happens in older runtimes that don't support async/await or awaitPromise.

Hi @roblourens do you have any ETA for this?
Thank you so much

Is there a way to configure a vscode debug launch session to simply enable the --experimental-repl-await flag behind the scenes?

I tried adding it to the runtime args of the node VM running the debugged code, but it didn't change the behaviour, although I can prove the flag works on that VM interactively (allows top-level await).

However, I may not understand exactly how the debug console session comes into existence. If it's not a repl in a node VM then that may be why I can't enable it. Are there other flags which control the debug-session VM?

Params in args in the launch config will be passed to node.
