Re: how to write a scheme function to override glissando properties
This slide function is great. I always have to tweak the glissando
command because it is always too small.

Hi Marc,
thanks for your solution but I'm still trying to find out what's wrong
with the scheme function I posted. I discussed the need for this function
with Carl and he gave me some advice:
http://www.mail-archive.com/lilypond-devel@gnu.org/msg32745.html.
It might be impossible to find a general set of values for staves and tab
staves. If I don't succeed I learned something about writing scheme
functions, at least. Maybe you can spot the mistake in the function?
Hm, I don't know what's wrong - I tried something like
slide =
#(define-music-function (parser location len thick beg end) (number? number?
ly:music? ly:music?)
#{
\once \override Glissando #'minimum-length = $len
\once \override Glissando #'thickness = $thick
\once \override Glissando #'springs-and-rods =
#ly:spanner::set-spacing-rods
$beg \glissando $end
#})
myMusic = \relative c' {
\slide #10 #5 a4 b4\3
}
\score {
\new Staff {
\new Voice {
\clef treble_8
\myMusic
}
}
\new TabStaff {
\new TabVoice {
\myMusic
}
}
}
and that doesn't work either. I don't understand why ...
I think what happens is that the start note, passed to your function,
is already wrapped up in an object. \glissando is meant for use with a
single note, rather than with a music object.
You can use scheme to add the `start glissando' property to the object though:
\version 2.13.40
slide = #(define-music-function (parser location length startnote)
(number? ly:music?)
#{
\once\override Voice.Glissando #'minimum-length = $length
\once\override Voice.Glissando #'springs-and-rods =
#ly:spanner::set-spacing-rods
#(begin
(set! (ly:music-property $startnote 'elements)
(cons (make-music (quote GlissandoEvent))
(ly:music-property $startnote 'elements)
))
(ly:export $startnote))
#})
{ \slide #7 a'' e'' }

This is reasonable but unfortunately the glissandi staves and tab staves don't have the same length in print even when they were given the same value for minimum-length... Ok, since the property is called minimum-length, of course the greater value wins - the note heads are spaced wide enough so that the greater amount of #'minimum-length fits between. The shorter glissando line will be expanded appropriately... Thinking about it, I think that the default bounds are too big for tablature. Have a look at http://lilypond.org/doc/v2.13/Documentation/internals/glissando In #'bound-details, the padding is set to 1.5 * staff-space, and because the staff-space in tablature is 1.5 times the normal space, the glissando lines are way too far away from the fret numbers. Setting these to 1 will improve the output. \once \override TabVoice.Glissando #'bound-details = #'((right (attach-dir . 0) (padding . 1)) (left (attach-dir . 0) (padding . 1))) a''2 \glissando e' Regards, Marc ___ lilypond-user mailing list lilypond-user@gnu.org http://lists.gnu.org/mailman/listinfo/lilypond-user

Needless to say, that I don't understand it either...
Apparently it's not even possible to override the length of a
glissando in one context without changing the look of the other
context. Look at this:
\version 2.13.44
slides = {
a2\glissando b2\3
}
\score {
\new Staff { \clef treble_8 \slides }
\new TabStaff { \slides }
\layout {
\context {
\Voice
\override Glissando #'minimum-length = #10
\override Glissando #'springs-and-rods =
#ly:spanner::set-spacing-rods
\override Glissando #'thickness = #3
}
\context {
\TabVoice
\override Glissando #'minimum-length = #1
\override Glissando #'springs-and-rods =
#ly:spanner::set-spacing-rods
\override Glissando #'thickness = #10
}
}
}
The values for minimum-length in different contexts influence each
other. The highest value wins. This is reasonable but unfortunately
the glissandi staves and tab staves don't have the same length in
print even when they were given the same value for minimum-length...
Sorry for being not very helpful.
No, no, I appreciate your input very much.

Hi Jakob,
thank you, too for your solution. I did have a look at the section on
adding articulation to notes in Extending but I think I have a
different problem. I actually wanted to write a function that calls
\glissando and overrides its properties more or less for the whole
score. I'd even prefer to tweak the command \glissando in order to
get the same output in a Staff and a TabStaff. But I probably didn't
look in the right place. I just found the definition of \glissando in
property-init.ly:
glissando = #(make-music 'GlissandoEvent)
But I didn't manage to override its properties. Maybe you know how to
do it?
Thanks,
patrick
