I'm not content with my skills in engraving coda jumps. I suspect Lilypond could do better if I knew how to code it.
My current method is to use a rehearsal mark to concatenate some text and a Coda glyph, and then apply a trial-end-error X-offset until it lines up the way I want it to, and then when the layout changes, I usually have to adjust it again. In my example code, the first score uses \toCoda to create coda glyph centered very nicely over the barline. I modify the visibility properties of the rehearsal mark so that if the barline is broken, the coda mark will not be visibile at the beginning of a line. I also set the outside-staff-priority so that the coda glyph will be engraved in between the staff and the volta brackets. And yes, many of the coda marks are placed oddly in the code, to demonstrate that the break-visibility property is doing what I want it to do. This code also scales well to the smaller size shown in the second example, although I don't understand why a magnification factor of 1.0 results in a smaller size. The third variable 'txtCoda' contains a more detailed representation of what I like to use, but it requires manual manipulation to get it to align, and one size does not fit all. How can I create a coda mark which: 1) aligns the X-center line of the coda glyph with the X-center of the barline; 2) places the arbitrary "to Coda" alongside the glyph, while leaving the glyph itself centered over the barline; and 3) can be scaled easily (text and glyph) to different sizes, without disturbing the alignment of the coda glyph to the barline? An elegant solution to this would be very welcome. Thank you for your time. Jim
