The fourth example engraver here:

Running this code in 2.24 crashes on initializing the engraver with In

(expecting Item): ().

Thanks for the report. I suppose you did not realize that this “Extending LilyPond” resource is not part of the official documentation, it’s something I wrote up and maintain externally (unlike the official Extending Manual, which lives at https://lilypond.org/doc/v2.24/Documentation/extending/index.html). Thus, any feedback you have should be sent to me privately, not to the bug list.

Best,
