Hi Andrew,

Thanks for your reply!

Indeed I was not aware of your work -- actually, this is the first time I am
using openlilylib. That library is quite amazing!

Indeed. I had a look at your slashes, and of course your solution is very
powerful when you need fine control, but what I was looking for was simply a
solution that takes care of it automatically. For my own scores, these
functions I adapted here work very well (in particular because I tend to
force the beam of grace groups to be horizontal on my own compositions, so
my slashes are consistently in the correct position).

If you have the interest in creating some snippets for automatic slash using
your functions, that would be great of course, and I am sure me or other
people will find use for it! But as of now, as I said, this here suits me
very well, and I am not good enough with Scheme to try adapting your
solution. When I asked for help with the bug in my function, I was not
really looking for "improvements" to the results itself but rather some help
to create a conditional for a specific case (grace notes without beam) which
was giving me an error, and now that David has spotted the issue and sent me
a solution it's all working fine for me.

Take care!
Gilberto
