How to get Staff context-id from a grob?

[Jan Rosseel]

Hello,

 

I have a problem that I’ve been trying to crack, but I’m failing.

 

In my backend, I am processing grobs, and I would need to get the context-id of the StaffSymbol that a certain grob belongs to.

 

Here’s the bigger picture:

 

 

\new Staff = foobar { 

… << some music>>>

}

 

For all grobs that orginate from notes in “some music” I need to be able to get to the “foobar” string.

 

Is this possible from scheme code?

 

Regards,
