Hello,
how can a snippet in the LSR be corrected?
http://lsr.dsi.unimi.it/LSR/Snippet?id=633
is not perfect, it should look like
---[snip]---
%LSR Contributed by Frederico Bruni
%% Hide fret number: useful to draw slide into/from a casual point of
%% the fretboard.
hideFretNumber = { \once \override TabNoteHead #'transparent = ##t
\once \override NoteHead #'transparent = ##t
\once \override Stem #'transparent = ##t
\once \override NoteHead #'no-ledgers = ##t %<--- NEW
}
Oh, I forgot: it would look even better (since the LSR is on 2.12) with
the following
additions:
% the next definition and the layout block are necessary only for
versions <2.13.6:
#(define-public (glissando::calc-tab-extra-dy grob)
(let* ((original (ly:grob-original grob))
(left-bound (ly:spanner-bound original LEFT))
(right-bound (ly:spanner-bound original RIGHT))
(left-pitch (ly:event-property (event-cause left-bound) 'pitch))
(right-pitch (ly:event-property (event-cause right-bound) 'pitch)))
(if (< (ly:pitch-semitones right-pitch) (ly:pitch-semitones left-pitch))
-0.75
0.75)))
\layout {
\context {
\TabVoice
\override Glissando #'extra-dy = #glissando::calc-tab-extra-dy
}
}
music= \relative c' {
\grace { \hideFretNumber d8\2 \glissando s2 } g2\2
\grace { \hideFretNumber g8\2 \glissando s2 } d2 |
\grace { \hideFretNumber c,8 \glissando s } f4\5^\markup
\tiny "Slide into"
\grace { \hideFretNumber f8 \glissando s } a4\4
\grace { \hideFretNumber e'8\3 \glissando s } b4\3^\markup \tiny
"Slide from"
\grace { \hideFretNumber b'8 \glissando s2 } g4 |
}
\score {
<<
\new Staff {
\clef "G_8" % <--- NEW
\music }
\new TabStaff {
\music }
>>
}
---[snip]---
otherwise the tablature won't fit to the displayed notes; moreover,
the ledger lines
of the hidden notes are still visible (ok, if the clef is G_8, then
the ledger lines won't be there anymore, but for sake of maximum
usability, the
snippet should be prepared for users sliding around on the sixth
string :-).
Thanks
Marc
