Re: Controlling markup vertical position

[Menu Jacques]

Hello,

As it turns out, using \tempo solves the issue:

Cello =  \relative f {
  \clef "bass" \key f \major \time 4/4
  \tempo "Bassi"
  g,2 \f
  \tempo "Vcl."

  des''4 \p ( c4 ) | % 18
}

\relative {
  \Cello
}

Re: Lilypond 2.19.31 on openSUSE Leap 42.1

[Andrew Bernard]

In fact, it libffi.so is a dynamic dependency of three libraries:

/usr/lib64/libpangoft2-1.0.so.0
/usr/lib64/libpango-1.0.so.0
/usr/lib64/libgobject-2.0.so.0

What is that supposed to be?  I am not even sure what this does.  Maybe
we should check that case and flag an error: there is no context
specified to which this is supposed to apply.  You probably want
something like a

\Staff

before the \RemoveEmptyStaffContext.

So you might well find that libffi 6 has been around a while but Leap

Does anybody have an idea where the libffi dependency comes from?  It's
not linked explicitly as far as I can tell.


Don't wonder abut troubles, SuSE is Windows owned.

This is a downside, but in general I find it can be managed pretty well. So

I'm trying to format directly in LilyPond an interview (the single

LaTeX just because of this minor part of the book.


I've two questions:

1) There's any way to place the text on two columns AND let LilyPond 
reflow it depending on the available space on the page?
The documentation contains an example where you must decide in 
advance what goes into column left and what into column right. I'd 
like to avoid this.


No, Lily can’t currently typeset in multiple columns. I’m 
surprised to see that there is no feature request in the tracker. 
This should be available both as a paper variable (say \paper { 
columns = 2 }) and as a markup command/markup list command(?).


Searching "two AND columns" in the open bugs list didn't return any 
relevant issue.
I guess that this should be added? Do you have better keywords to 
search?







2) I'm trying to create a shortcut for formatting the question and 
the answer.
I wonder if the new \etc can be used for this purpose or should I 
rather create a markup function.


IIUC, \etc can only be used for music functions (at least until 
now… :-)). So you need a custom markup or markup list command.


Ok, adapting the example in the Extending manual was easy:

\version "2.19.31"

#(define-markup-list-command (question layout props args) (markup-list?)
  #:properties ((par-indent 2))
  (interpret-markup-list layout props
#{\markuplist \justified-lines \bold { #args } #}))

#(define-markup-list-command (answer layout props args) (markup-list?)
  #:properties ((par-indent 2))
  (interpret-markup-list layout props
#{\markuplist \justified-lines { #args } #}))

\markuplist {

In a way it seems natural that this can interfere with an engraver like
the ones involved in the annotations. Unfortunately I'm at a loss as to
what that may mean and how to proceed.

I don't think there's anything you could do better.

There is no openLilyLib mailing list yet, and I don't think it makes
much sense to have one. I may do that if there should arise objections
about the respective discussions being off-topic here ...

So if you have questions you should post them on lilypond-user. However,
if you feel you are encountering a problem you can (should)
(additionally) open an issue at

Re: Lilypond 2.19.31 on openSUSE Leap 42.1

[Andrew Bernard]

On openSUSE Leap 42.1 I find using ldd:

ldd /usr/lib64/libpango-1.0.so.0
linux-vdso.so.1 (0x7ffe94bb6000)
libgobject-2.0.so.0 => /usr/lib64/libgobject-2.0.so.0 
(0x7f7bd8393000)
libgmodule-2.0.so.0 => /usr/lib64/libgmodule-2.0.so.0 
(0x7f7bd818e000)
libglib-2.0.so.0 => /usr/lib64/libglib-2.0.so.0 (0x7f7bd7e7f000)
libm.so.6 => /lib64/libm.so.6 (0x7f7bd7b7e000)
libpthread.so.0 => /lib64/libpthread.so.0 (0x7f7bd7961000)
libc.so.6 => /lib64/libc.so.6 (0x7f7bd75b9000)
->libffi.so.4 => /usr/lib64/libffi.so.4 (0x7f7bd73b)
libdl.so.2 => /lib64/libdl.so.2 (0x7f7bd71ac000)
libpcre.so.1 => /usr/lib64/libpcre.so.1 (0x7f7bd6f45000)
/lib64/ld-linux-x86-64.so.2 (0x557b63f22000)

So it would seem to come from pango.

Now, the download of lilypond fails to run because it wants libffi.so.6. The 
above information comes from a build from source on openSUSE Leap 42.1 , which 
so far appears to run, at least, but I have not extensively tested it.

Strange LilyPond crash

[Marc Hohl]

Hi list,

I am currently reworking some older stuff that compiled perfectly under 
2.13.x


Yes, I used convert-ly on all files, but nevertheless, I encountered a 
strange problem:


I have a drum part, consisting of an upper and a lower DrumVoice, and if 
I try to compile the full Drum score, I get a segfault.


I tried to reduce the number of notes and realized that if I include 
either drum voice, everything is fine.


Next, I included the complete upper voice and commented out parts of
the lower drum voice. Now lilypond compiles upto a certain point in the 
score, but if I include *one more note*, I get the segfault again.


Well, we talk about 70 measures with eighths, quarter notes and some 
triplets, so I don't believe that LilyPond runs out of memory.


I am currently using 2.19.32.

Any ideas of what's going wrong here?

Marc

Apologies.  In my enthusiasm to boil this down to a minimal example,
I've created an oddball that just looks like Lilypond-abuse. Here it is
again with an extraneous staff restored.  
I don't think there is any problem with lilypond itself.  However,
either this user or Urs' ScholarLy annotation code has a
problem/limitation.
\version "2.19.21"

\include "openlilylib"
\useLibrary ScholarLY
\useModule scholarly.annotate

#(display "Scholarly loaded\n")

\setOption scholarly.annotate.export-targets #'("plaintext" "latex")

\score {
  \context ChoirStaff <<

Well, that seems like a reasonable thing one might want to do.
Currently it's just music expressions and markup commands that yield to
\etc but markup list commands make perfect sense to me as well.

I'll see whether I can submit something like that.

Re: temporarily forcing notes to ignore LyricText width

[William Marchant]

Hi,
I have found that it helps for short sections of music if the words in 
the offending lyrics are all made the same length.  thus "I could do"  
associated with three 8th notes, might become "__I__ could __do__"  This 
makes the spaces even out.

Cheers,
Bill

Hello all,

In the attached snippet, you can see how the notes are evenly spaced when there 
is enough overall width (page 1), but become unevenly spaced when the width is

An automagic fix for this issue is part of the GSoc Lyric overhaul, and hence 
is a long way off from being implemented [if ever!]. In the meantime, I would 
love a tweak that would allow me to tell Lily to ignore the LyricText grobs 
when spacing that measure; I would then go and nudge the individual grobs left

Unfortunately, I can’t seem to find the correct incantation. (Note: I’ve tried

Hello Jacques

Thanks for this example, but this forces you to decide in advance which 
part of text should go into each column. If you change the paper size, 
you'll have to move some text from one column to another. I was hoping 
there was a markup list command to achieve this automatically.

Uh, actually it would appear that I got this wrong: I confused
\RemoveEmptyStaffContext (the old way of doing this which overwrites the
\Staff context definition with a fixed one) with \RemoveEmptyStaves (the
recommended way of doing this).

Maybe we should replace \RemoveEmptyStaffContext with a scheme function
referencing the current setting of \Staff.

And/or add a convert-ly rule to do that.  Either way is not as "backward
compatible" as the current code but I rather doubt that backward
compatibility is doing anybody a favor here.

Programming error with removeEmptyStaves

[Jean-Charles Malahieude]

Hi all,

How could I find the culprit in a 5 staves score which looks all right? 
The logs say

Those errors disappear as soon as I either remove

from the layout block, or randomly omit one or some of the staves.

thanks David, you've solved my problem (and probably saved Urs some work
too).  Somehow I had missed that there is a new, better, way to remove
empty staves.  With the new syntax the problem with ScholarLy goes away.
Thanks also to  Trevor Ba?a for his blog post at

Scheme question: convert a range

[Simon Albrecht]

Hello,

The subject certainly seems cryptic – it’s difficult to summarize, but 
an example will make it clear immediately.
I want to write a scheme procedure, which takes a pair like #'(3 . 7) 
and returns a list with all the numbers in the range: #'(3 4 5 6 7)

How is this done most easily?

TIA, Simon

Re: Testing requested: new manuscript viewer tool for Frescobaldi

Hi Simon, hi Federico,

thanks for your advices. Yeah, it works! :-)
This is a really cool feature. I hope it will soon be available for 
windows as well.


Cheers,
Klaus

It is a feature of Python (in which frescobaldi is written) that a 
program needn’t be compiled/installed to be run. You need to
1. get the source files for frescobaldi and python-ly from 
, either by downloading 
 
and  or using 
‘git clone’ and checking out the ‘manuscript-viewer’ branch.
2. add the following three lines to ~/.bashrc, where path/to/python-ly 
and path/to/frescobaldi are the paths to the respective directories:

# add python-ly to PYTHONPATH
PYTHONPATH=path/to/python-ly:$PYTHONPATH
alias frescobaldi='path/to/frescobaldi/frescobaldi'
3. and then you can just run 'frescobaldi' on the command line to test 
the feature.


I hope that this is correct and will help; if there are any questions, 
feel free to ask.

Re: how to simulate or vectorize free hand curve notation

Dear Ryan,

Oh my goodness. Almost as hair raising as the contemporary scores I have to

Hi JM

You could try using extra-offset:

Cello =  \relative f {

Oh, I see, I had overlooked that aspect.

Maybe a Python script reading the text in and creating something like the above 
with the text split into as many such elements as required by the geometry of

#(define (bookGenerator please))

[Pierre-Luc Gauthier]

Hi there,

I have been trying to make a book generator function using scheme
inside Lilypond.

The book generating function itself works but I am the goal would be
to have another function to iterate over a list of parts to be
generated as books.

I cannot seem to find what I am doing wrong since I am just starting
to understand (even slightly) how to use scheme in Lilypond.

Here is what I have to show :

%%%

\version "2.18.2"

\language "english"

piccoloPart = \new Staff {
  \new Voice {
\relative c' {
  d4 e fs g |
  a1\fermata |
}
  }
}

bassPart = \new Staff {
  \new Voice {
\relative c {
  \clef bass
  c4 d e f |
  g1\fermata |
}
  }
}

#(define compilePart
   ;; This function is used to do and engrave a book
   ;; $segment should be a musical expression
   ;; $name should be a string for the book output suffix
   (define-void-function (parser location segment name)
 (ly:music? string?)
 (let ((paper #{ \paper {} #})
   (layout #{ \layout {} #})
   (book #{ \book { \score { $segment } } #}))

   (ly:book-process book paper layout name

% _This_ is to test the compilePart function
%\compilePart \piccoloPart #"piccolo"
%\compilePart \bassPart #"bass"

parts = #(list
  ;; This is a list of parts to be engraved
  '("piccolo" . #{ \piccoloPart #} )
  '("bass" . #{ \bassPart #} ))

#(define processAllParts
   ;; This function is used to call the compilePart function for
   ;; each part entry in the parts list.
   (define-void-function (parser location parts)
 (list?)
 (map
  (lambda (p)
(let (
   (name (car p))
   (music (cdr p))
   (show (lambda (name thing)
   ;; This is in the hope to see what's wrong
   (begin
(display (string-append "\nAbout to show "

Re: Text-spanner text repeated at start of line

[David Sumbler]

Thanks for the help with this problem.  It has taken me until now to
have a chance to experiment further with it.

I ended up not using the \markupMap idea, because I don't in any case
want the "(minim=138) part of the tempo marking to be bold.

So I have ended up with:
accelVivaceText = {
  \override TextSpanner.line-X-offset = #'(0.5 . 0.5)
  \override TextSpanner.line-Y-offset = 0.5
  \addTextSpannerText \lyricmode {
\markup \upright \bold "accelerando molto" -- 
\markup \upright \bold al --
\markup \upright \concat {
  \bold "Vivace (" \general-align #Y #-1 \tiny \note #"2" #UP " = 138)" } } 
}

Some time in the future, a real text-spanner mode would be useful for
this sort of case, so that the problem of wanting the instruction to
appear once in the score and once in each of the parts would be solved,
hopefully, just as it is currently for normal tempo markings.

As it is, the relevant passage in my quartet file looks like this (using
\parallelMusic):
% bar 40
\tag #'forScore {
  c8 a b a b \accelVivaceText a \startTextSpan gs a \noBreak |
  c8 a b a b a gs a |
  c8 a b a b a gs a |
  c8 a b a b a gs a | }
\tag #'forPart {
  c8 a b a b \accelVivaceText a \startTextSpan gs a \noBreak |
  c8 a b a b \accelVivaceText a \startTextSpan gs a \noBreak |
  c8 a b a b \accelVivaceText a \startTextSpan gs a \noBreak |
  c8 a b a b \accelVivaceText a \startTextSpan gs a \noBreak | }
% bar 41
b8_\cresc gs a gs a gs fs gs |
b8_\cresc gs a gs a gs fs es |
b8_\cresc gs g gs g fs gs fs |
b8_\cresc gs g gs g fs e fs |
% bar 42
a8 fs gs fs gs fs e fs |
fs8 gs es fs es fs fs es |
gs8 a gs g a g a g |
gs8 fs e gs fs gs fs fs |
% bar 43
gs8 e fs e fs fs es fs |
fs8 gs es fs es fs fs es |
fs8 g fs es fs g fs g |
es8 fs g fs g fs g fs |
% bar 44
\tag #'forScore {
  g8\ff \stopTextSpan es fs es fs fs fs fs |
  fs8\ff g! es fs es fs fs fs |
  fs8\ff g fs es fs es fs es |
  es8\ff fs g es fs es fs fs | }
\tag #'forPart {

  fs8\ff \stopTextSpan g! es fs es fs fs fs |
  fs8\ff \stopTextSpan g fs es fs es fs es |
  es8\ff \stopTextSpan fs g es fs es fs fs | }

Hello,

As it turns out, using \tempo solves the issue:


Well, it depends on what you’re typesetting there, but a \tempo

very fragile.

But how about:
%%
\version "2.19.30"

\relative f {

That’s closer to what the artisanal engraver did, at least for the "Bassi".

Re: Controlling markup vertical position

[Kieren MacMillan]

Hi Jacques,

> As it turns out, using \tempo solves the issue:

OH, PLEASE DON’T DO THIS!

Don’t use a MetronomeMark (which is the grob generated by \tempo) where a 
TextScript (which is the grob generated by \markup) is appropriate. This *may* 
appear to “solve the issue”, but really it doesn’t, and it certainly adds a 
whole bunch of new issues — immediately obvious or eventually to surface — 
which needn’t ever be encountered if you simply use the correct grobs and 
tweaks to begin with.

Re: temporarily forcing notes to ignore LyricText width

Hi All,
Try my snippet attached.  I know it's not automatic, but it does work.

Hello all,

In the attached snippet, you can see how the notes are evenly spaced when there 
is enough overall width (page 1), but become unevenly spaced when the width is

An automagic fix for this issue is part of the GSoc Lyric overhaul, and hence 
is a long way off from being implemented [if ever!]. In the meantime, I would 
love a tweak that would allow me to tell Lily to ignore the LyricText grobs 
when spacing that measure; I would then go and nudge the individual grobs left 
or right as necessary to make the measure look great.

Unfortunately, I can’t seem to find the correct incantation. (Note: I’ve tried 
setting LyricText.X-extent and #'extra-spacing-width, but with unexpected and 
not uniform results.)

Thanks,
Kieren.

p.s.  Bonus points if this tweak can be applied “externally” (i.e., via the

I tried to reduce the number of notes and realized that if I include

Well, we talk about 70 measures with eighths, quarter notes and some

I am currently using 2.19.32.

Any ideas of what's going wrong here?


Not off the top of my head. I think there’s nothing for it except 
further testing. Please post the smallest version of the code you could 
find which sports the error. One might check

– with which version the error first occurs
– using the same number of notes, but uniform in pitch and/or rhythm
– using normal Staff and Voices (though this will likely not show the 
problem)

– etc.
in order to find some other way of boiling it down.
And if all of this doesn’t work, then you already have got a minimal 
example to use for a bug report – ‘from which nothing can be removed 
without making the bug disappear’.

That’s all ‘wisdom’ I can contribute…

Re: how to simulate or vectorize free hand curve notation

[Ryan Michael]

I see in the Lilypond Reference That you can specifiy for example, the
shape of a Phrasing Slur by giving control points. E.g.

\shape #'((0 . -1) (5.5 . -0.5) (-5.5 . -10.5) (0 . -5.5)) PhrasingSlur

However, is there a way to do this outside of a slur context? Namely I
would like to draw curves like the above slur but without

actually engraving noteheads, just the curve itself.

Well, if the numbers are ascending you could do something like:

(define (expand-interval arg)
   (iota (- (1+ (cdr arg)) (car arg)) (car arg)))

(display (expand-interval '(3 . 7)))

If not, something like this would work:

 (let loop ((elt (car arg)) (result '()))

Re: Controlling markup vertical position

Hi Jacques,

If you want to duplicate the original, you need to [almost] right-align the 
“Bassi”:

  SNIPPET BEGINS
\version "2.19.30"

Cello = \relative f {
  \clef "bass"
  \key f \major
  \time 4/4

\new Voice { \voiceOne \dynamicUp des'4-\tweak self-alignment-X #RIGHT \p( 
^"Vcl." c4) }
  >> \oneVoice | % 18
}

\relative {
  \Cello
}
  SNIPPET ENDS

I’ve also done a few other tweaks and code adjustments in this snippet, to get 
you closer to [how I might code] the original.

Hope this helps!

Re: how to simulate or vectorize free hand curve notation

Hey Ryan,

One way to cheat is to export as an svg file and then edit it in
something like Inkscape and then export that as a pdf. You can create
all sorts of really cool vector graphicy things pretty easily that
way. Unfortunately you cannot then translate that stuff back into your
Lilypond file so it is a one-way street and needs to be the last step.

Re: Scheme question: convert a range

Hi Simon,

Fellow listers have posted many answers while I was cooking up this one. All 
good!


(use-modules (srfi srfi-1))

(define (range r)
(let ((start (car r))
(end (cdr r)))
(iota (+ (- end start) 1) start 1)))

That’s pure Scheme of course. Thomas Morley’s answer is more in the vernacular 
of lilypond. But I just wanted to point out the list functions you would expect 
to exist but don’t in R5RS are in SRFI-1. But lilypond looks after all that for 
you.


The purely recursive solutions are nice, because lists are intrinsically 
recursively defined, but Functional programmers tend avoid doing that and 
prefer to hide the recursion behind generalised functions such as iota. A lot 
easier on the brain and the maintainer. Just a matter of FP style. There are 
many views!

In this case you already have a structure amenable to splitting:
 - 34 bars melody
 - 2*4 bars coda
So you could have melody variable and a coda variable,
and introduce a third variable for the gap;
eg it would then be easy to omit the gap from midi.


But I agree that involving s1 is a depressing sort of hack.


See if you like the attached pauseStaffBL hack any better.
No skips needed - it maltreats bar lines instead.
The demo does '\pauseStaffBL 40 \break' at the end of measure 9.

Actually development for this initial version came to a halt when I went

Frescobaldi, but as this tool is awaiting significantly more development
we think we *have* to iron them out completely.

I'd be interested in the answer too, as I'm getting a flood of emails hours
after they were sent.

Re: how to simulate or vectorize free hand curve notation

[Andrew Bernard]

Hi Ryan,

I feared as much. I assume you are talking about the curve in the extract from 
your sample, attached for reference.

Lilypond slurs are Bezier curves that have two control points. That means you 
can’t create arbitrary wavy curves like that with that object – you need a 
large number of control points for that. (As an aside, if you do want to shape 
slurs there is an even nicer function that \shape called \shapeII in the 
openlilylib library.)

So what are the alternatives? Take a look at the NR section on graphics in 
markup.

http://lilypond.org/doc/v2.18/Documentation/notation/graphic

You could use the path command, which will allow an arbitrarily long list of 
curveto commands – consequently as many control points as you want. Since 
lilypond is not a graphical drawing tool, this approach, for the curves you 
show, would take a very large amount of effort, compiling and adjusting.

You can also use Postscript directly in markup, and you could write Postscript 
path commands. This has similar drawbacks to the above, but you can use 
Ghostscript as a development environment to see the curve. Again, painstakingly 
difficult. Also, if you incorporate Postscript into your lilypond file, it will 
not come out if you need to render the output in SVG.

The least nice way is to export to SVG and then create your curve in the 
document in Inkscape, or other SVG editor. This is a last resort, because once 
you go out to Inkscape you can’t come back again into lilypond.

Lilypond graphics markup allows the inclusion of EPS (encapsulated Postscript). 
So you could draw the curve in Adobe Illustrator, export as EPS, and include as 
an EPS file in lilypond.

I engrave vastly complex New Complexity School scores by a composer colleague 
of mine. The modernist notation challenges lilypond at every turn and every 
measure, so I am used to these issues! In the end, often, I feel defeated by 
the composer who has nothing more than an HB pencil!

There's
https://codereview.appspot.com/270640043/
Once it's finished it may help for tasks like this.
`make-bow-stencil' allows for some nice features. Just have to find
the time to finish it...

 Cheers,

Re: #(define (bookGenerator please))

[Pierre-Luc Gauthier]

So, after reading the "Automated processing of multiple books" thread
and few hours trying to figure this out, I am still not able to make
it work.
The higher order function "for-each" somehow cannot call the
"compilePart" function and Lilyponds GUILE interpreter returns "Wrong
type to apply".

Why?

Simple tests allowed me to prove that "for-each" *can* call functions
like "display" but not my "compilePart".

I am very very new to scheme and let alone scheme inside the pond and
I really got a kick out of this journey finally understanding why
those #, #', #{, #}, $, parser, location, etc were there in the first
place.
It's really satisfying.

Here is the code for my MWE.


\version "2.18.2"

\language "english"

piccoloPart = \new Staff {
  \new Voice {
\relative c' {
  d4 e fs g |
  a1\fermata |
}
  }
}

bassPart = \new Staff {
  \new Voice {
\relative c {
  \clef bass
  c4 d e f |
  g1\fermata |
}
  }
}

compilePart = #(define-void-function ( parser location music name)
 ;; This function is used to do and engrave a book
 ;; $music should be a musical expression
 ;; $name should be a string for the book output suffix
 (ly:music? string?)
 (let ((paper #{ \paper {} #})
   (layout #{ \layout {} #})
   (book #{ \book { \score { $music } } #}))
   (ly:book-process book paper layout name)))

% _This_ is to test the compilePart function
%\compilePart \piccoloPart #"piccolo"
% \compilePart \bassPart #"bass"

parts = #(list
  ;; This is a list of pairs containing parts informations
  '("piccolo" . piccoloPart)
  '("bass" . bassPart))

% _This_ is to test that the data can be extracted succesfully from the list
%\compilePart #(cdr (car parts)) #(car (car parts)) % First entry
%\compilePart #(cdr (car (cdr parts))) #(car (car (cdr parts))) % Second entry

% Somehow _this_ does not work.
%{#(for-each
  (lambda (p)
(let ((name (car p))
  (music (cdr p)))
(compilePart music name )
))
  parts)%}
