[musicxml2ly] handling empty staffs
Hi Bug Squad, I’ve encountered a very strange behaviour when converting a musicxml file to ly and then to svg… Lilipond version 2.19.83 The musicxml file has two measures in a grand staff with two voices. In the first measure both voices start in the lower staff (G3, E3) and in the second measure both voices are the upper staff (E5, C5). This is a simplified version of an Hanon exercise where you usually start at a very low octave and repeatedly increase some note sequence up to a very high octave… I can’t tell whether this is an error of musicxml2ly or lilipond … What do you think? I’ve attached the musicxml file, the ly and the generated svg and a screenshot of how it should look like… Thank you very much and with kind regards Florian ___ bug-lilypond mailing list bug-lilypond@gnu.org https://lists.gnu.org/mailman/listinfo/bug-lilypond

Seems to be a case of the first context not being alive by the time the
other notes come along. If you manually added some spacer rests of
suitable length to the upper Staff...
\context Staff = "1" <<
\mergeDifferentlyDottedOn \mergeDifferentlyHeadedOn
{ s1*2 } %% Keeping context alive.
>>
...then the output appears correct.
Not sure how this helps with musicxml2ly though. Is it capable of
computing the length of music to be able to insert such spacer rests
automatically? Or is there some way to link two contexts together so
that they keep each other alive without needing manual intervention?

issues with musicxml2ly
Hello bug-squad, I ran into three issues when converting a .musicxml file generated with MuseScore into LilyPond: 1) the .ly file outut by musicxml2ly seems to have a weird encoding and outputs an error. There are many hidden characters which I had to remove manually in order to compile the .ly file. 2) slur placement is not taken into account. The entry below has the argument placement set to "below" but musicxml2ly outputs it as a standard pair of ( ) instead of _( _) 3) MusicXML contains information about al niente hairpins but music2xml does not use those. Perhaps this feature could be added? This is how the .musicxml looks like: [...music under which the hairpin is...] Cheers, Gilberto ___ bug-lilypond mailing list bug-lilypond@gnu.org https://lists.gnu.org/mailman/listinfo/bug-lilypond
Request: Print actual number of pages after compiling
This isn't so much a bug as an annoyance. Frequently when I'm typesetting music, I'm trying to resize the output to fit on the minimum number of pages (while remaining readable, of course). When Lilypond is compiling, one of its messages is "Fitting music on 1 or 2 pages..." Obviously, in this situation, I want to know the exact number of pages without re-opening the .pdf file. Could someone add a one-line statement to print out the actual number of pages, near the "Success: compilation successfully completed" message? --- Christopher Heckman ___ bug-lilypond mailing list bug-lilypond@gnu.org https://lists.gnu.org/mailman/listinfo/bug-lilypond

A ly-file can contain multiple books or bookparts or a mix of it.
I don't know how to cover every case, but for the case of a single
book(part) you could do:
\paper {
#(define (page-post-process layout pages)
(format #t "\n\tCurrent book-(part) has ~a pages" (length pages)))
}
\score { { R1 \pageBreak R } }
Cheers,
Harm
