Is it possible to intercept command line output in real time?

Question

Python

Good afternoon, OS - windows 7.
I am writing a simple program for myself, in which the archiver (winrar) is launched via the command line (via the subprocess module), extracts files and closes. Winrar sends the extraction progress to the console, can I intercept it in real time and bind it to a variable?

Answer 1

This solution is much prettier. Naturally, some refinement with a file of the SubprocessProtocol class will be required. I recently checked - it works, and you can simultaneously intercept both stdout and stderr.
PS Just in case, the data parameter in pipe_data_received is bytes, so it needs to be decoded into a utf-8 string. If under Windows there are Russian file names, you will have to figure out what encoding rar uses. Most likely - cp866.
