Re: Creating LilyPond Object Models

[Paul Morris]

Hi Urs,

It was inspired mostly by Carl’s post and working on Jianpu notation.  A 
tutorial on this is not a bad idea.  That said: 

(1) it would benefit from fitting into, or coming after, a broader overview of 
LilyPond like Carl has written

(2) it sounds like the way we create scheme engravers may change in the near 
future (based on David Kastrup’s post from earlier today) so probably best to 
wait until after that

(3) it might be good to add some more documentation of this to the official 
extending manual first.

For now maybe I’ll just add my example with comments to the LSR as a quick 
temporary measure.

Cheers,
-Paul
