Hello,I’d like to suggest rearranging the instrument names in LSR 650 using \center-column (more elegant in my eyes). Attached you find an updated version of the file. Do you approve?

Hi, 2014-08-01 12:13 GMT+02:00 Phil Holmes <m...@philholmes.net>:----- Original Message ----- From: "Janek Warchoł" <janek.lilyp...@gmail.com>% I'm not 100% satisfied with this code, but i think it's better % than the snippet in the docs. Maybe someone would like % to submit an update? I don't really have enough time now.It's a snippet from the LSR and will be updated considerably anyway in thenext build. You might like to check out http://lsr.di.unimi.it/LSR/Item?id=650Thanks for info, Phil. Well, the new version of the snippet suffers from exactly the same problem as the old version, except _more so_. The fact that the snippet defines *three* separate staff contexts for the "Low" parts, which don't split _at all_, is a complete and utter abomination, and it almost gave me a heart attack. This is unbelievably ugly, and against good programming practices. I have expanded my code from my previous email to also show two staves converging into one (see attached). Please note that i didn't have to make *any* changes to the \score block structure - i have just added commands for new arrows and written more music to the _existing_ variables. I believe this proves my code is superior to the one from the snippet. cheers, Janek =============================================I've updated the LSR with your snippet: the code base will have this following an LSR import.-- Phil Holmes _______________________________________________ lilypond-user mailing list lilypond-user@gnu.org https://lists.gnu.org/mailman/listinfo/lilypond-user
