Import snippet from LSR

New page

Whilst staves can be grouped and nested using a variety of notations, such as <code>SystemStartSquare</code> or <code>SystemStartBrace</code> (which can be achieved automatically through the <code>systemStartDelimiterHierarchy</code> property), some editions of symphonic music use SystemStartBracket at different levels, which may result in unwanted collision between bracket tips.

Here is a possible workaround, which masks the extraneous part of some bracket tips in order to give the impression that they merge with the lower-level bracket.

<lilypond version="2.24.0">
%% If newer version like 2.25.xx are used, `normalize-color` needs to be applied.
%% This should become the default once LSR moves to 2.26.
#(define my-color
(if (eqv? (second (ly:version)) 25)
(normalize-color white)
white))

maskUpperTip =
#(lambda (grob)
(let ((mask (ly:round-filled-box '(-1 . 1.25) '(-1.14 . 0) 0)))
(ly:stencil-stack
(ly:system-start-delimiter::print grob)
Y UP
(ly:make-stencil
(list 'color my-color (ly:stencil-expr mask))))))

maskLowerTip =
#(lambda (grob)
(let ((mask (ly:round-filled-box '(-1 . 1.25) '(-0.0 . 1.14) 0)))
(ly:stencil-stack
(ly:system-start-delimiter::print grob)
Y DOWN
(ly:make-stencil
(list 'color my-color (ly:stencil-expr mask))))))
