Re: Any possibility to define a new accidental-style ?

[Valentin Villenave]

Hello everybody,

a few months ago, I started this thread to ask how to define an
accidental-style I really needed --and still need.

Rune had kindly answered me, but I guess he hadn't got the time to
figure out how to do it; this is why I ask again today, in case
someone couls help me.

Moreover, this is really a popular way to print accidentals in
contemporary music, and I would reaaly like to see LilyPond handle it.

Let me sum up this behavior:

> --the first accidental in a bar is printed (like in 'default style)

> --if the same note gets natural, even at a different octave, a natural

> --sometimes, cautionnary naturals signs can even be printed in the

As Rune pointed out, the only tricky part here is to distinguish if a
note is immediately repeated, or reappears after a few other notes.

I hope someone will be able to find a way...

Cheers,
Valentin
