[tinomai]

Langkit uses pipes which is deprecated since Python 3.11 and removed in Python 3.13.

ae43ef0 bump minimal Python version to 3.11.

At least

• langkit/compiled_types.py
• langkit/libmanage.py
• langkit/utils/init.py

are affected.

See PEP 594 for details.

Hello,

Thank you for reporting this. We just merged the removal of pipes imports: dbacb9b

Note that we don’t have yet the infrastructure internally to reliably test support for Python 3.13, so there may be other issues left, which we’ll address proactively after our infrastructure gets updated.
