RE: Ineffective \override

[Fairchild]

Mats -

I had scoured the documentation prior to posting, but missed the thread
Werner initiated.

For posterity, here is a list of things that work in v 2.4.3:

   \override NoteHead           #'transparent = ##t
   \override Stem               #'transparent = ##t
   \override Dots               #'transparent = ##t
   \override Beam               #'transparent = ##t
   \override Rest               #'transparent = ##t
   \override Accidental         #'transparent = ##t
   \override Slur               #'transparent = ##t
   \override PhrasingSlur       #'transparent = ##t
   \override Hairpin            #'transparent = ##t
   \override TextScript         #'transparent = ##t
   \override Script             #'transparent = ##t
   \override DynamicText        #'transparent = ##t
   \override Staff.BarLine      #'transparent = ##t
   \override NoteHead           #'no-ledgers  = ##t

The last two may not be buggy, but I agree with Werner that they are fishy,
and with your characterization as tricky.  Certainly they are inconsistent
from a user view.  I endorse Werner's plea for documentation.

Thanks for the help.

I really recommend you to read the full chapter on "Changing defaults". The
answer to this specific question is in the section "Layout tunings within
contexts" with reference to "Changing context properties on the fly".

This is indeed a tricky special case. See
http://lists.gnu.org/archive/html/bug-lilypond/2005-04/msg00133.html
and the other emails of that thread to learn more.
