I'm trying to create an execution environment/shell that will remotely execute on a server, which streams the stdout,err,in over the socket to be rendered in a browser. I currently have tried the approach of using subprocess.run with a PIPE. The Problem is that I get the stdout after the process has completed. What i want to achieve is to get a line-by-line, pseudo-terminal sort of implementation.
My current implementation
test.py
def greeter():
for _ in range(10):
print('hello world')
greeter()
and in the shell
>>> import subprocess
>>> result = subprocess.run(['python3', 'test.py'], stdout=subprocess.PIPE)
>>> print(result.stdout.decode('utf-8'))
hello world
hello world
hello world
hello world
hello world
hello world
hello world
hello world
hello world
hello world
If i try to attempt even this simple implementation with pty, how does one do it?
