attachment-offset at slurs

[Roland Goretzki]

Hello list,

meanwhile I'm using lilypond-snapshot 2.4.1.
The standard-solution for slurs is very fine so far. :-)

Nevertheless I'm missing the attachment-offset, which was implemented
with lilypond 2.2.6 (or earlier?), and which I found (together with
ratio and height-limit) the very best solution to fine-tune the slurs.

      (You can have a look at it on

         http://www.mutopiaproject.org/cgibin/piece-info.cgi?id=489

      where the score has very much slurs and the whole output is nearly
      like a copy of the original, and without all possibilities of
      fine-tuning slurs in 2.2.6 this wouldn't have been possible.)

Now with 2.4.1 I've tried to manipulate with slur-details as described
in the documentation, but without any real success, because it is very,
very ugly for a not-programmer like me, if there doesn't exists a
detailled explanation. :-(

    \override Voice.Slur #'slur-details = #'((region-size . 4)
    (head-encompass-penalty . 1000.0) (stem-encompass-penalty . 30.0)
    (closeness-factor . 10) (edge-attraction-factor . 4) (same-slope-penalty
    . 20) (steeper-slope-factor . 50) (non-horizontal-penalty . 15)
    (max-slope . 1.1) (max-slope-factor . 10) (free-head-distance . 0.3)
    (free-slur-distance . 0.8) (extra-object-collision . 50)
    (accidental-collision . 3) (extra-encompass-free-distance . 0.3)
    (head-slur-distance-max-ratio . 3) (head-slur-distance-factor . 10)
    (absolute-closeness-measure . 0.3) (edge-slope-exponent . 1.7))

Is there another explanation-place in the documentation, which I didn't
find?
Otherwise I would beg for re-implementing the attachment-offset. :)
(Or perhaps it could be re-implemented in every case?)

Thanks for any help!

Best Regards           Roland
