BTL does not load on FreeCAD versions using Python 3.9

[DavidHenri008]

I just installed the latest 0.9.9 version in my FreeCad 0.21.2 and unfortunately, the icon is not displayed. I rebooted several times and still not showing...

Edit: I just saw some error

Looks like you are using a FreeCAD with an old Python version. The error references a line that uses the new "match" statement, which is available starting from Python 3.10.

[DavidHenri008]

I have python version 3.10 installed. But I am not pointing to it in the settings

[knipknap]

I am not sure how that works on Windows. Perhaps FreeCAD ships with an included Python? In any case, does it work when you define the path?

[DavidHenri008]

Unfortunately not. I still have the issue after I set the path.

Python 3 is not compatible with python 2. Do you run this with version 2 or 3 of python?

[knipknap]

Python 2 is EOL. BTL uses Py 3 only.

I just pushed a commit to remove the match statement. It should now be compatible with Python 3.9

[DavidHenri008]

I will give it a try. It is strange because the match statement was supported from 3.10 and up... I will try to identify which version of python is executed by my FreeCad.

[DavidHenri008]

Oh wow... look at this, I am somehow running version 3.8:

[DavidHenri008]

So on windows, the python version is distributed with FreeCad...

[knipknap]

It shouldn't matter anymore, BTL master should work anyway.

As the compatibility issue was fixed, I am closing the issue. Feel free to re-open if the problem persists.
