Hi Harm,
thanks a million! It certainly does get me started. I think this should be
added to the snippet repository. I could prepare a snippet illustrating your
code and some other overrides of details of automatically generated fret
diagrams. Something like that:
\version "2.19.15"
barre = {
\once \override FretBoard.before-line-breaking =
#(lambda (grob)
;(display (ly:grob-property grob 'dot-placement-list))
(ly:grob-set-property! grob 'dot-placement-list
(cons '(barre 6 1 1) (ly:grob-property grob 'dot-placement-list))))
}
fMajorEShape = { <f,-1 c-3 f-4 a-2 c'-1 f'-1> }
\new FretBoards {
\override FretBoards.FretBoard.size = #'2
\override FretBoard.fret-diagram-details.barre-type = #'straight
\override FretBoard.fret-diagram-details.finger-code = #'in-dot
% \override FretBoard.fret-diagram-details.dot-color = #'white
% \override FretBoard.fret-diagram-details.finger-code = #'below-string
\override FretBoard.fret-diagram-details.number-type = #'roman-upper
% \override FretBoard.fret-diagram-details.orientation = #'opposing-landscape
\override FretBoard.fret-diagram-details.mute-string = #"M"
% \override FretBoard.fret-diagram-details.label-dir = #DOWN
\override FretBoard.fret-diagram-details.open-string = #"0"
% \override FretBoard.fret-diagram-details.string-count = #4 % doesn’t work
% \override FretBoard.fret-diagram-details.fret-count = #3
\barre
<f,-1 c-3 f-4 a-2 c'-1 f'-1>
}
What do you think?
Oh wait, I just tried to transpose the chord but the barre indication is always
printed at the first fret:
\version "2.19.15"
barre = {
\once \override FretBoard.before-line-breaking =
#(lambda (grob)
;(display (ly:grob-property grob 'dot-placement-list))
(ly:grob-set-property! grob 'dot-placement-list
(cons '(barre 6 1 1) (ly:grob-property grob 'dot-placement-list))))
}
fMajorEShape = { <f,-1 c-3 f-4 a-2 c'-1 f'-1> }
gMajorEShape = { \transpose f g { \fMajorEShape } }
\new FretBoards {
\barre
\transpose f g { \fMajorEShape }
\barre
\gMajorEShape
\barre
<g,-1 d-3 g-4 b-2 d'-1 g'-1>
\set FretBoards.minimumFret = #3
\barre
\gMajorEShape
}
Is there any way to move it up the fretboard?
Thanks again!
patrick
