Hello,
I just had this idea about a *new* method of spacing.
Maybe this is nuts, and it's almost a hack, but I'm seeing that it could
work, so, please, leave me a feedback.
The idea is create an invisible "obstacle", with a length set in
staff-space units, between grobs.
Then, assign a position to each grob.
The obstacle has a grey color in the following example, but you can use
white color as well.
Here is the example:
%%%%%%%%%%%%%%%%%%%%%%%%
#(define (SpaceBeforePos1 length) #{ \tweak
TextScript.outside-staff-priority 100 ^\markup{ \draw-line #(cons 0
length)} #})
#(define (SpaceBeforePos2 length) #{ \tweak
TextScript.outside-staff-priority 200 ^\markup{ \draw-line #(cons 0
length)} #})
#(define (SpaceBeforePos3 length) #{ \tweak
TextScript.outside-staff-priority 300 ^\markup{ \draw-line #(cons 0
length)} #})
#(define (SpaceBeforePos4 length) #{ \tweak
TextScript.outside-staff-priority 400 ^\markup{ \draw-line #(cons 0
length)} #})
#(define DynamicTextAtPos1 #{ \once \override
DynamicLineSpanner.outside-staff-priority = 110 #})
#(define DynamicTextAtPos2 #{ \once \override
DynamicLineSpanner.outside-staff-priority = 210 #})
#(define DynamicTextAtPos3 #{ \once \override

110 #})

310 #})

410 #})

#(define TupletBracketAtPos4 #{ \once \override
TupletBracket.outside-staff-priority = 410 #})
#(define OttavaBracketAtPos1 #{ \once \override
