Change clefs can be recognised by the glyph name as well. You can try 
putting some sort of (display glyph-name) in the body of the

out more.

Re: How can I hide a volta bracket?

[Scaramoucherz]

Actually, I figured out one way to display the music as I want. I set the
\repeat volta to 7 (since there really are 7), then used the \markup command
to correct the text. I set up two scores: one for the Refrain, and one for
the Verses. I then set up the output to display the Refrain first, then the
Verses. It looks as I want.

program error: mis-predicted force

[Partitura Organum]

Hi all,

Every now and again I see this error when engraving a score"program 
error: mis-predicted force" and then a bunch of numbers. But the score 
looks okay so I ignore it. And since the error never comes with a line 
in the music file where the error originates I never know what is 
actually wrong.


Tonight it happened again. This time I have been able to narrow down the 
source of the error to the next snippet (sort of "Minimal Error Throwing 
Example") :


%% start

\version "2.19.59"

#(set-global-staff-size 18)

\score {
  \new Staff
\relative c'' {
  \key bes \major
   es4 d c8 cis d bes
  \grace {a16 c}
  }
}

 end

All elements are needed for the error to occur. With another 
global-staff-size: no error. Remove one of the notes: no error. Remove 
the key signature: no error. Remove a grace note: no error


So, what am I doing wrong here?

Regards,
Auke

How can I hide a volta bracket?

[Scaramoucherz]

I am working with a song that is set up as:
Refrain
  Ending 1-6
  Final ending
Verses

By setting the \repeat volta 9, I can get the music to show Ending 1-6, and
Final okay. However, there is a volta bracket over the Verses. How can I
hide the volta bracket over the verses, so that the music looks correct?

Thanks

Actually, maybe this makes more sense (for the two functions), since
make-dot-list ought to, well, return a list instead of a combined
stencil.  I've just quoted the two functions I adapted:

#(define (make-dot-list l1)
   (map
(lambda (dl) (make-dot (ly:pitch-notename dl)))
l1))

#(define-markup-command (complete layout props the-chord)
   (ly:music?)
   (ly:stencil-scale
(reduce
 ly:stencil-add
 empty-stencil
 (append
  (make-dot-list (map (lambda (m) (ly:music-property m 'pitch))
   (extract-named-music the-chord 'NoteEvent)))
  (engrave-back)))
1 1))

Your original:

% ici on défini les points qu'on fait sur le piano
#(define (make-dot-list l1)
   (if (null? l1)
   empty-stencil
   (ly:stencil-add
  (make-dot (ly:pitch-notename (car l1)))

  )))

OK, your function is intended to return a list of dots, but you only
call make-dot on the first element of the list.

You need to apply make-dot to every element of your pitch list, and
then combine these into a stencil.  To combine stencils, I use reduce:
(Documentation here:
https://www.gnu.org/software/guile/docs/docs-1.8/guile-ref/SRFI_002d1-Fold-and-Map.html#index-append_002dmap-3619).
I found reduce and fold somewhat difficult to grasp at first, but they
definitely repay study.

My rewrite:

#(define (make-dot-list l1)
   (reduce
ly:stencil-add
empty-stencil
(map
 (lambda (dl) (make-dot (ly:pitch-notename dl)))
 l1)))

%

Your original:

#(define-markup-command (complete layout props the-chord)
   (ly:music?)

 (ly:stencil-scale
  ( ly:stencil-add
(engrave-back)
(make-dot-list (map (lambda (m) (ly:music-property m 'pitch))
  (extract-named-music the-chord 'NoteEvent)))
 )
  1
  1))

Here, the error messages are instructive.  The function ly:stencil-add
expects its arguments to be individual stencils, but you are providing
it with *lists* of stencils (the result of calling engrave-back and
make-dot-list--the latter corrected as I show above, of course!)

The solution once again is to first create a list of stencils, then
combine them using reduce:

#(define-markup-command (complete layout props the-chord)
   (ly:music?)
   (ly:stencil-scale
(reduce
 ly:stencil-add
 empty-stencil
 (cons
  (make-dot-list (map (lambda (m) (ly:music-property m 'pitch))
   (extract-named-music the-chord 'NoteEvent)))
  (engrave-back)))
1 1))

%%

Of course, scaling the stencil to 100% is both axes is a bit redundant!

Another observation: the greenish dots are hard to see.

I've attached the whole file (with some formatting changes that helped
me read it better).

Hope this helps,

David

Hi Ewen,

I should also mention that Kent Dybvig's text The Scheme Programming
Language is freely available online here:

http://scheme.com/tspl4/

And since lilypond uses guile (1.8 curently) you should also read the
reference manual (which is of course not a tutorial, but essential to know
about):

https://www.gnu.org/software/guile/docs/docs-1.8/guile-ref/

Re: Apply a music-function script to all elements of a list

Hi Ewen,

For learning Scheme, this is quite good:

Teach Yourself Scheme in Fixnum Days:

https://ds26gte.github.io/tyscheme/index-Z-H-4.html#node_sec_2.1.4

A surprisingly good resource.

If you want to get serious, then SICP is essential, the text from the
legendary MIT course.

Structure and Interpretation of Computer Programs, by Abelson and Sussman.

Freely available online:

https://mitpress.mit.edu/sicp/

Just having the hardback of this book next to me on my bookshelf makes me
feel good.

There's a 20 video course on Scheme by Abelson on the net somewhere I seem
to recall.

And I think the MIT 6.001 course lectures from 198 or so are now released
on youtube under a Creative Commons licence.

Hi Simon,

Thanks for your answer. I tryied to add a score in my file to have a
bebugging compilable file.

I get an error when I compile your code (join file) : Wrong type (expecting
Stencil): (# # # # incdiato82.ly
   # # # #)

If I take off the 'apply' from 'apply ly:stencil-add , then the lines you
add works but not the make-dot-list function, and if I delete it, the
make-dot-list works but not the background...

I never learned Scheme at school and this language is not so obvious, and I
have a lot of problems to understand it. Even with guile documentation I
need to have the basic and actually I didn't found anything which explain
from zero. Do you know any good book or tutorial / course ?

I try to do my best,

Thanks for your help again,

ewen

Denemo's MusicXML import is very crude, it doesn't even try for chord
names, lyrics and probably quite a lot of other things, just
concentrates on reducing the labor of putting in all those dratted notes
and durations again. The upside of this is that it will often get you
*something* while musicxml2ly generally used to give up if it
encountered something bad in the input.

Happy to test out musicXML import via Denemo any time, in the hopes of
finding places to improve it.

I thought(hoped) that we had got past the

Unfortunately it seems not much has changed since my early 
experience in the 80s. 

I only posted this because I thought that it might be useful to
those working on musicxml2ly.

And, by the way, the chordnames above the staves vanished
somewhere in your import.

I've now got two versions that I can try to work with.

So, thanks for having a go.

Unfortunately MusicXML is IMHO just a rag-bag of ideas for fields to
describe poorly documented music features, every program devises its own
interpretation of the "standard".

FWIW I imported this via Denemo and it looked ok - not sure what it
