--handle-input not working with Expo?

Description: I'm trying to run expo start along with another command, I'm using --handle-input but nothing happens when I press r (reload) or i (open on iOS)
Expected Behavior: I would expect the commands to be forwarded to the Expo CLI
Environment: macOS, Node lts/jod
Reproduction: concurrently -k -n 'mobile-client,backend' -c 'red,green' --handle-input 'yarn expo start' 'yarn workspace backend run dev'

Sounds like it's detecting whether it's in TTY mode. I don't know how this is used, but the function name is pretty suggestive:

https://github.com/expo/expo/blob/988261c1a1405aca1f0a32f28bf068306aa03a8c/packages/%40expo/cli/src/utils/interactive.ts#L4-L5

If you pass the --raw flag to concurrently, expo might respond - but at the cost of not having output prefixed.

It'd be cool to have some env variable to force interactivity.

Thanks. Do you think the raw option could be enabled just for a specific command rather than for all of them? So that I can have the output prefixed for all the other commands I run?

Yep, this should already be possible today though through API mode.

concurrently([
	{ name: '...', command: 'foo', raw: true },
	{ name: '...', command: 'bar' } // raw: false by default
])

Docs (it's lacking raw in there, but it works)

That said, I wouldn't say no to making the CLI --raw flag accept indices/names as a way to pick which commands use it.

so would it be --raw 0 and/or --raw label-a right? Could it support multiple raws at the same time? (--raw 0 --raw 1)?

Yes, but I'd favour using comma separators like in most other flags that accept multiple inputs (e.g. --prefix-colors, --names or --success), so --raw foo,bar,1,2,3

Any news on that issue?

I'm using concurrently to run multiple Vue apps at once (concurrently "pnpm:dev:*") and I am unable to send command to any of them.

@ByScripts

Hey @ByScripts, did you try with --raw?
If it works, it'll confirm that your dev:* scripts are detecting it's not a TTY, and therefore ignore input forwarding.
