crashing the goroutine with something I'd expect is 'reasonable'

[knewter]

proc = Porcelain.spawn_shell("bash --no-editing -i", in: :receive, out: {:send, self()})
Proc.send_input(proc, "ls")

This crashes the goroutine and I get a reasonable error struct sent to self(), but I'd have expected it to just work properly vis-a-vis sending ls (without a newline, but meh) into the bash process that's running. spawn produced the same behaviour (and spawn seems more reasonable here obv. but whatever)

Can you explain what I should be doing in order to get this sort of thing to work? In Port I could do this:

port = Port.open({:spawn, "bash --noediting -i"}, [:stderr_to_stdout, :binary, :exit_status])
send(port, {self, {:command, "ls\n"}})

Which bash version do you have? Mine does not recognize --no-editing. So what happens is that the process exits, then you send input to it, and it triggers the panic.

This is a bug, Porcelain should return an error instead. But I don't think it's the kind of bug you are implying here. Can you test with just bash -i?

BTW, the --noediting flag works for me with spawn_shell().

Yeah I just came here to tell you "herp derp, random dash in my bash option that I glossed over last night". Thanks for the reply, and sorry for the mis-reported "bug".

You have made just the right typo to find a bug in goon :) Not the bug you have reported, but still a crash. I'm working on fixing it.

So thanks :)

For what it's worth, the goroutine also crashes when the process it's told to send to no longer exists - at which point it spews a go stacktrace in your iex.
