hey! I have a Process that gives me both inputStream and errorStream (stdout and stderr respectively), and I need to log the output's of both as soon as they come in. what's the best way to handle that? I guess just doing inputStream.bufferedReader().forEachLine {...} would block and thus not allow stderr to be handled, thus blocking the process
Any ideas?

Use two threads

[Leon K]

is that the only option? no input-stream combination stuff or something?

There is no async io on it so yes.

A crazy workaround would be to use ProcessBuilder redirectTo to two files and read from those async.

[spand]

Not sure what the problem with two threads are though.

NuProcess (github) seems to be an option

Also for fun I wrote a coroutine that polls InputStream::available() and returns a flow. Though this is polling and you release the thread via delay. Not optimal either
