This happens when you are triggering a python file inside of xcode. Does not happen on terminal.

Does xcode allocate a real pseudo terminal? Can you run for instance Vim and Emacs in there?

Hi, I just tried importing it into the visidata project to try and improve the prompt that is in there already but got the same error. I know it was a long shot but I thought I'd try! I'm pretty sure visidata is built purely on curses with no additional libs, which in a way makes it a little hard to dev for if you need higher abstractions! So, given this, is there a way to pass the current screen object to prompt_toolkit for it to use? Long shot but I thought I'd ask! TIA!
