Compilation time (was: Generate \scaleDurations procedurally)

Hello, When trying to compile the complete score of the piece below (88 staves and 120 quarter notes), I noticed it was taking many hours (I didn't finish the compilation). Trying with shorter versions, I got the following compilation times: - 2x quarter notes -> 16.7", - 4x quarter notes -> 1'17",

Re: Compilation time (was: Generate \scaleDurations procedurally)

Hello Lib, this slowdown appears to be induced by forbidBreakBetweenBarLines = ##f This might be understandable: Your code will division at 30/1, 30/2, ..., 30/88, which might induce a relatively large number of potential break points. This appears to be too much for the line breaking algorithm

Re: shifting accidentals horizontally

Hello Werner, this Problem is not caused by my solution, but generally by your approach of taking the Notes with collision applied (the 8th note bb on the left, the b,e on the right) and shifting the bb until it is right of the others. This still means that the will be offcentered. So this wi

Re: shifting accidentals horizontally

Or rather there is the NoteColumn.ignore-collision property. If set to #t the Note column will not be added to any NoteCollision grob. The problem here is that in this case there need to be no positional correction. So we require some additional check in the engraver to apply this correction d

Re: Compilation time (was: Generate \scaleDurations procedurally)

Dear Jean (and Valentin!), thank you so much! The page breaker was the problem, and after applying your fix the compilation time on my machine is around 3 minutes. I'll soon be able to finish the score, just need to fix the duration ratio and the layout. Again, thank you! Lib P.S. I just found an o

question to generating random pitches snippet

Dear community, I discovered the snippet that lets you generate random pitches in Lilypond. How does Lilypond "know" what are the lowest, what are the highest pitches? How could I change that? Thanks for Your help Stefan

Re: How to make a blank page

Hi Many thanks to you all for your help. I thought you might like to know that I found Simon's solution the best one. Perhaps my minimal example was a little too pared down. In reality, I use headers and footers on my music as well. So my minimal example begins: Jean Abou's suggestion \version "2
