Semantic prompt

[KoviRobi]

Hi,

I enjoy PyREPL in Python 3.13, thank you it's great! Especially that now it means python -m asyncio has a proper REPL. I was thinking it could do with semantic prompt integration (e.g. I have C-b C-p set up in Tmux to select the previous output).

To achieve this, I put the following into my PYTHONSTARTUP

import sys

def semantic_displayhook(obj, displayhook=sys.displayhook):
    print("\x1b]133;C\x07", end="", flush=True)
    displayhook(obj)
    print("\x1b]133;D;0\x07\x1b]N;aid=python;cl=v\x07", end="", flush=True)

def semantic_excepthook(exc, val, tb, excepthook=sys.excepthook):
    print("\x1b]133;C\x07", end="", flush=True, file=sys.stderr)
    excepthook(exc, val, tb)
    print("\x1b]133;D;1\x07\x1b]N;aid=python;cl=v\x07", end="", flush=True, file=sys.stderr)

sys.displayhook = semantic_displayhook
sys.excepthook = semantic_excepthook

sys.ps1 = "\1\x1b]133;A;aid=python;cl=v\x07\2>>> \1\x1b]133;I\x07\2"
sys.ps2 = "\1\x1b]133;P;k=c\x07\2... \1\x1b]133;I\x07\2"

I thought I would put this here in case it can be added to defaults in case it's useful to others? I could open a PR if you prefer, looks like the hooks might fit into runcode and maybe get_prompt for the ps1/ps2?

Thank you,
Robert

AFAIK CPython forked the code in this repo and modified it to add new features. So probably you want to report your findings directly on CPython's repo?
