Qt Contributors Summit 2022 - Program/QtScrypt

Session Summary

Some time ago, I wrote a hackathon project to enable Python scripting within C++ applications - the outcome was cool :). Due to the similarities, I decided to call it QtScrypt, because it kind of follows a similar idea as QtScript, but with Python. I would like to present the proof of concept I have, and if it's interest from someone else to start the development and create a proper project out of this idea.

Notes

taken by Friedemann Kleint

• Hackathon Project running Python from C++ (Qt Script)
• Idea: Simplify CPython API/Create a high level API for it
• QScryptEngine with an evaluate() function
• QVariant-based (due to mixed types in Python)
• QScryptModule/QScryptFunction
• Some confusion about super ()
• Application bindings exposing QObjects (as historically in Qt Creator)?
• Python scripting of Qt Design Studio was considered , but no capacity
• Use Python instead of JavaScript in Qt Design Studio would be nice (developer POV) , for example Property Editor
• Enable use of scientific packages from Python
