yeah, that’ll work. i’m still confused about that whole factory and
protocol business :)
the only change to my previous solution would then be:
class StdOutReaderProtocol(SubprocessProtocol):
def __init__(self, reader, loop=None):
self.reader_prot = StreamReaderProtocol(reader, loop=loop)
def pipe_data_received(self, fd, data):
if fd == 1:
self.reader_prot.data_received(data)
else:
print('stderr from subprocess:', data.decode(), file=sys.stderr,
end='')
