There are a number of useful functions: musicMap (defined in
ly/music-functions-init.ly); for-some-music, map-some-music,
fold-some-music (in scm/music-functions.scm).  Maybe you can get use
out of one of these, either directly or as inspiration.

The lists should have a few examples of at least one or two of these.

Hope this helps a little.

Implement extra-offset for system positioning (issue 324810043 by david.nales...@gmail.com)

2017-04-27 Thread david . nalesnik 

Reviewers: ,

Message:
Please review.  Thanks!



Description:
Implement extra-offset for system positioning

Add the property 'extra-offset to 'line-break-system-details.

It is possible to position systems absolutely using the properties
'X-offset and 'Y-offset of 'line-break-system-details.  Placement,
however, is relative to the top left of the usable space, and can
be difficult to gauge without considerable trial and error.

An 'extra-offset property allows easy movement of systems relative
to where they currently are on the page--either through their
default positioning, or as a result of absolute positioning through
'X-offset and/or 'Y-offset.

System separators will be properly positioned. (Thanks go to Thomas
Morley.)
