Comment #5 on issue 824 by address@hidden: Enhancement: anchors in the music
stream
http://code.google.com/p/lilypond/issues/detail?id=824
Looking at my rather cryptic mails in the bug report, it looks like I
should have been more explicit. The attachment "cash.ly" contains
definitions for the two music functions \anchor and \addAt which, given the
desired input (copied into the end of cash.ly) produces the desired output.
The modification with map-music-function happens in-place, so one should
preferably use this in the same manner as Scheme functions reverse!, namely
when the result is assigned back to the source or not used otherwise
anymore.
When this does not seem user-friendly, adding a ly:deep-music-copy call in
the code will sort this out at the cost of memory use (typically cleared up
by the garbage collector eventually). A different option would be to
open-code the part currently done by map-music-function and create copies
only for those parts of the structure that change by \addAt.
Suggestions about where to put that code in what form?
