Yours takes no precious vertical space, and I don't have to bother with shifting around till it's at the best place. I am sure that I am breaking some engraving 'rule' but it's a nice glyph. I've seen it in Bosworth Co. scores only, but they seem to use it exclusively instead of the common shape. But I also made up the habit of telling the ones I hand my scores out to that I use a unusual symbol for d'al segno, to avoid irritations.

Re: lilypond authors, release notes, announcements
It looks like we're getting close to the first release candidate. - could any new contributors check: http://lilypond.org/authors.html to make sure they're there? if you have git access, you should be in development team, and choose your own title. If not, you should be listed in current contributors, in whichever categories you think is relevant. Our list of translators looks particularly slim. Send patches for: Documentation/included/authors.itexi - who wants to write release notes? Do it in the same style as previous ones. Keep it brief because various places have size limits. - based on the written policy: http://lilypond.org/doc/v2.13/Documentation/contributor/major-release-checklist - we're not using any potential requirements. - I'm not paying any attention to unsorted stuff. In particular, I'm not going to send any announcements anywhere other than lilypond.org. If you think we should be sending announcements, then start making/updating a list. Since I haven't been very active on the LilyPond lists the last year, I think it would be appropriate to remove my name from the Current development team list. After a computer upgrade, my certificates to the git repository don't work anymore and I gave up trying to fix it, so for the moment I don't have any working git access. Could I please ask Graham or some other kind soul to edit the file and move my name to an appropriate place (perhaps the trash bin :-) ).

You are correct. I looked at the history of the file containing this, using http://git.savannah.gnu.org/gitweb/?p=lilypond.git;a=tree and found that one change is titled: RemoveEmptyStaves: Remove Harakiri engraver before adding it again. This reason is explained there. It is to avoid ever having two engravers of the same type, which caused problems. This kind of detail often goes without comment in code, or at most a 3-word avoid having two, because there would otherwise be so many such comments. Thanks for pointing this out. I can't see a good reason for not adding the comment to the file: If RemoveEmptyStaves is called twice, two Hara_kiri_engravers would be added, which leads to a warning. This code makes sure that no previous Hara_kiri_engraver is left before adding a new one. ? -- Phil Holmes ___ lilypond-devel mailing list lilypond-devel@gnu.org http://lists.gnu.org/mailman/listinfo/lilypond-devel

Re: Score follower
Konstantin, I have a metadata patch floating around that can help you kludge your way through this. It is not too hard, but will require some work: 1) Create a sort of metadata property for whatever grob you wanna trace. 2) for those grobs, create an override for the print method that first calls the correct print method and then uses the generated stencil for xy coordinate info, returning this stencil at the end of the function after having harvested its coordinates. You can have pretty prints to the command line of the grobs' metadata and coordinates, or you can write these to a file using Scheme. If this sounds like Chinese, lemme know and I can try to cook up a simple proof of concept depending on what you want to do.
