The topic was to re-invent the wheel yet again and create a terminal emulator.
I hesitate to say this but one approach is to consider the curses module as described by our very own Alan Gauld in a book: https://www.amazon.com/Programming-curses-Python-Alan-Gauld-ebook/dp/B091B85 B77 The topic is how to make a terminal emulator and as Alan mentions, each kind of terminal may accept various kinds of escape sequences. There are files available the are normally used by curses to get a description of sorts of the capabilities and details of a terminal like a VT100 that curses can use to decide what stream of bytes to send to update a screen. You might be able to use something similar, or better, to see what your terminal emulator should emulate. And, it may even be possible for you to emulate lots of terminals with the same basic code. -----Original Message----- From: Python-list <python-list-bounces+avi.e.gross=gmail....@python.org> On Behalf Of Alan Gauld via Python-list Sent: Tuesday, May 14, 2024 3:07 PM To: Gordinator <gordina...@gordinator.org>; python-list@python.org Subject: Re: Terminal Emulator On 14/05/2024 18:44, Gordinator via Python-list wrote: > I wish to write a terminal emulator in Python.

And even a VT330 is quite different from a VT100 although sharing a common subset of control codes. And if you start looking at graphical terminals things get even more interesting! The other thing to consider is whether it will be a standalone app or a GUI component. If the latter do you want to expose your own API or clone the manufacturers? Or both?! Or you could make it an object that can be used both in GUIs and in "robotic" or "batch" mode. So many options. Most of the specs are available online and there must be dozens of terminal emulators around written in C so you should have plenty of sample code to study.
