Re: Horizontal brackets

[Siska Ádám]

Hello,


actually, that was the first thing I tried, but it seems to me that the 
draw-line command doesn't exist in 2.10.25 (sorry for the prior 
misspelling, I'm using 2.10.25, not 2.10.10 -- although this doesn't 
really make a difference, I suppose). But, after tweaking a few hours 
with the code I got for the Bartok-pizz, I succeeded! :-)

That was the code I created:

%%%%%%%%%%%%%%

simpleBracket = {
 \override TextSpanner #'edge-text = #(cons
   (markup #:stencil
     (ly:stencil-add
       (ly:make-stencil
         (list 'draw-line 0 0 0 0 1)
         '(0 . 0) '(1 . 1)
       )
     )
   )
   (markup #:stencil
     (ly:stencil-add
       (ly:make-stencil
         (list 'draw-line 0 0 0 0 1)
         '(0 . 0) '(1 . 1)
       )
     )
   )
 )
 \textSpannerUp
 \once \override TextSpanner #'dash-fraction = ##f
}

[...]

<< \new Voice {
     \hideNotes
     \simpleBracket
     \stemDown g2.\startTextSpan \glissando e''4.\stopTextSpan
     \unHideNotes
   } {
     \simpleBracket
     <g dis'>2.\startTextSpan \glissando <e'' his'>4.\stopTextSpan
 } >>

%%%%%%%%%%%%%%


(The two voices are needed because I had to put this over a chord 
glissando, and also because I needed two brackets.)

Well, doesn't look very nice (as the distance between the two brackets 
is enormous, and also because one bracket is supposed to be nested into 
the other), but works!!!!!! :-) :-) :-)

Thank you very much!
Adam
