Script throws an error when all of the config Features are turned off

[mapadev]

When running the script with all Features turned off in config.yaml, the script throws:

line 226, in <module>
    splitFont()
line 151, in splitFont
    pyftfeatfreeze.main([f"--features=rvrn,{','.join(fontOptions['Features'])}", outputPath, outputPath])
TypeError: can only join an iterable

I think this happens due to an incompatible YAML file in that case, rather than a bug in the script. If you want to turn off all features you can specify an empty array in YAML like this:

Features: []

My thanks to both of you!

@mapadev, I appreciate the issue. I'll make the script handle this situation more gracefully before closing the issue.

@jwortmann thanks for the suggestion! I haven't tested it yet, but that does seem like a promising workaround until I can get to fixing this in a better way. @mapadev if you want to try it, please let me know if it works!

@arrowtype. The provided solution works for me as I just wanted to try some general settings without embedding any specific features.

Thank you @jwortmann.

Thanks so much for solving this, @jwortmann! I have added your helpful suggestion to the readme.
