Unfortunately, servers are usually configured without X forwarding enabled. And the functionality I am describing already exists for terminal-based programs, it's been reimplemented multiple times — see e.g. [0][1], it's just implemented with horrible hackery (by manually driving terminal, processing raw input and counting how much lines of text the terminal screen is probably displaying right now).
I just want to, e.g. write a simple Python program that has
for line in streaming_response.lines():
print(line)
in one thread, and
while True:
cmd = input('> ').strip()
if cmd == 'q':
break
if cmd == 'stop':
requests.post(...)
...
in another, and be able to input my commands without the echo of my input being teared up by the output. Erlang's shell can do that. Readline can be used to do that, but Python's bindings don't export the needed functions. Swapping out the sys.stdout/sys.stdin with my custom interceptors to do this manually... barely works, slow, ugly as hell and complicated.
