Looks good to me in 2.19.83 [current highest dev release not from git.] Andrew On 26/8/19 5:56 pm, Michael Gerdau wrote: Find attached my tests with the current (2 weeks old) git version.

Re: Horizontal spacing algorithm
Hi Chad,
FWIW I also had assumed you claimed such a change would be simple.
Anyway, have you actualliy tried the provided spacing examples given in
the (old?) article with a current version of lilypond?
Find attached my tests with the current (2 weeks old) git version. IMO
the current version of Lilypond does not have most (if at all!) of the
mentioned shortcomings, at least not at first glance.
Kind regards,
Michael

Re: Horizontal spacing algorithm
Hi Simon, Hardly an assertion when I used brackets and a question mark around the word “simple”. Anyway, the paper points out that Lilypond uses a version of Gourlay’s algorithm which works great except in examples like the ones he gives (polyrhythms). I’m aware that you can use proportional notation and uniform stretching to fix these examples. However, I find it interesting that the proposed solution incorporates what Lilypond actually does already (which is why it might not be as complicated as it seems). Am I the only one that is curious about this? Why does the horizontal spacing of the now-ancient SCORE software still look so good (in my opinion)?

Re: Horizontal spacing algorithm
Hello Chad, I am not aware that we currently have any developer working on or familiar enough with that area of the source code. Also, the assertion that implementing this would be simple is audacious to say the least: Even looking only at the examples given in that paper, it is by no means a given how much of that more proportional spacing is desirable (which the author even acknowledges himself). And in real life, there are very many other factors influencing spacing.
