displayLilyMusic -- tested

[Nicolas Sceaux]

Hi,

Here is a tested version of a `display-lily-music' function:
  http://nicolas.sceaux.free.fr/print-lily.scm

The test file (around 115 expressions):
  http://nicolas.sceaux.free.fr/test-print-lily.scm

The result (showing the differences between input and output, using
LilyPond from CVS, 2.5.30):
  http://nicolas.sceaux.free.fr/test-print-lily.pdf

To test it, place print-lily.scm in LilyPond's scm/ share directory.

  \version "2.5.30"
  #(use-modules (scm print-lily))

  displayLilyMusic = #(def-music-function (parser location music) (ly:music?)
                       (init-print-lily parser)
                       (display-lily-music music)
                       music)

  displayLilyMusicForceDuration = #(def-music-function (parser location music) 
(ly:music?)
                       (init-print-lily parser)
                       (display-lily-music music #:force-duration #t)
                       music)

  \include "italiano.ly"
  \displayLilyMusic \tag #'foo { dod re }

  \include "nederlands.ly"
  \displayLilyMusicForceDuration \tag #'foo { cis d }


This can be useful for getting a voice transposition, changing a
\relative snippet to absolute, having all durations printed on
notes, or debugging.

If you think this is not maintanable/good enough for the LilyPond
distribution, then I'll keep it somewhere else.
