Perhaps adjusting the system-system-spacing might work then.  For 
instance, consider setting the 'padding value, which forces a minimum 
distance between the skylines of the neighboring systems.  For systems 
that have no pedal marks, they shouldn't need to move assuming your 
'basic-distance is set to a reasonable value, but then the ones that 
have the pedal marks will get too close and push the next system lower.

That work-around does work. Thanks! Is there any way I could make that into a 
global setting - there are a lot of pedals in harp music. . .

Hi Rachel,

For adding some space between systems using markup, this little 'trick' 
could also work, if you want to try it. Does that help?

You cannot "resolve" this error since it is nothing a user should be
able to produce in the first place.  You may have been able to avoid
triggering it.

Ah, that's just superstitious.  Coding chaos could have gotten the same
result in an error like that.  Basically any change can cause a
different garbage collection sequence/behavior and thus mask the
problem.

I think "because" is the wrong word.  Defining an instrument variable
will take up significant memory space, so garbage collection will happen
at a significantly different place.  That's all.

thanks. OK, now I must confess I don't really know what was going wrong
exactly, but I resolved the error.

My main file had a bunch of variables defining each instrument, and a
separate file for score layout that placed them. A bunch of those variables
weren't yet defined; now that they are, the error no longer appears. I have
no idea how that relates to whether the viola part had accidentals on some
notes, or whether a rest was beamed, or whatever, but now it works again.

Coding discipline saves the day, I guess.

Thanks for the help. Sorry I couldn't get anything more productive, but I
couldn't for the life of me reproduce the error, at any point, using gdb.
It only failed in frescobaldi, and (apparently) only because some
instruments were still undefined.

Ugh, OK, now it's getting confusing.

Since gdb can't handle whitespaces in the path, I copied the whole project
directory into a new folder, and rewrote the includes and filenames to
eliminate whitespaces. If I try to compile the document in a path with
whitespaces, I get the ly:trampoline error; the *exact same file*, in a
path without them, fails under different conditions. Also, compiling fails
with those errors in frescobaldi, but not when I run lilypond on the file
from gdb (so there's no backtrace to post).

So now what?

space between text and the next system

1. between the bottom of the text and the following system 
2. between systems when there is no text.

When I get to the (gdb) prompt, I try this:
(gdb) run /[PATH]/plus-minus\ example\ 1.ly -file
Starting program:  /[PATH]/plus-minus\ example\ 1.ly -file
No executable file specified.
Use the "file" or "exec-file" command.

 What am I doing wrong with that command?

I cannot really find the location where this error would get triggered,

garbage-collection/trampoline error with beams and accidentals

[N. Andrew Walsh]

I have the following code:

\version "2.19.82"

\relative c' {
 \clef alto
 \override Score.Stem.stemlet-length = #0.75
 deh,2\f~ deh

 | %2
 deh2
 %\once \override Beam.positions = #'(2.5 . 1.5)
 c'16\rest[ deh,8.]

}

That compiles fine on its own. However, in the context of a full orchestra
score, I get an error with ly:trampoline if:

I uncomment the command for overriding Beam.positions
or
I tie the second deh in the first measure to the deh in the next, forcing
an accidental onto the deh8. that's beamed. (I'm using the "c'16\rest" to
force the rest into the middle of the Stave; is there a better way to do
that?)

So somewhere in there it's running into errors. From the previous posts on
this, it's something wrong with gdb that I need to track down; can someone
help me with debugging?

Coloring notes played on black piano key AND coloring accidental and key signature notes with different colors

Dear all,



Could you help me achieving the following objectives :



1)  In a piano staff, I would like to color (in blue) the notes that
are played on the black piano keys

And if possible :

2)  I would like to color differently the note that are played on a
black piano keys because of the key signature (in blue) from the notes that
are played on black piano keys because of accidentals (in red)

hit on it after long searches of the web and the archives, then based 
on somebody's guess. Somehow there needs to be some _explanatory_ 
document that actually explains these concepts in lilypond, because in 
this case and others, it's non-obvious (to my dim consciousness). I'd 
seriously offer to write such a text, but I am exactly the wrong person 
to do so because I am the one that is baffled still in general by these 
internals.
You're right that there is little specific documentation about 
extra-spacing-width. It is mentioned only briefly in the Learning 
Manual:


see http://lilypond.org/doc/v2.19/Documentation/learning/moving-objects

The problem is that there are far too many of these properties to 
document any but a tiny fraction of them with detailed explanations and 
examples. The approach we, the documentation writers, adopted was to 
attempt to teach people through the Learning Manual how to find 
pertinent properties for themselves by using the Internal Manual. Pretty 
well the whole of section 4 of the LM is devoted to showing users how to 
do this.


For example, look up TextScript in the All layout objects of the 
Internals Manual:


http://lilypond.org/doc/v2.19/Documentation/internals/textscript

There you'll find extra-spacing-width and Harm's recipe for setting the 
width of an object to zero.


Reading and understanding section 4 of the LM will greatly help you with 
your understanding (I hope; at least that was my objective!)


Actually, as to your last point about being baffled, it was my being in 
exactly that position several years ago that prompted me to write most 
of the LM. I reasoned that as I was in the same position as most new 
users I was well-placed to document the initial stages of learning to 
use LilyPond as I myself discovered them. That gradually lead to an 
understanding of the internals and the LM was the result.

Re: Ambitus per voice and Ez_numbers_engraver

[Gloops]

Hello Harm
Thank you for this correction ...
Is there any way to engrave the ambitus directly without going through
"note-head :: brew-ez-stencil" in order to avoid the head of the note?

Re: Organization of the piese part by part, not staff by staff

Hello everybody!
This case is usually used: we are instancing staffs, voices and 
putting notes into them. This is simply example:

\new GrandStaff <<
 \new Staff \rightHand
  \new Staff \leftHand

But I want to organizate the piece in other case. For example, I want 
to engrave any rondo. In first, I will instancing staff structure and 
write initialing:

\new GrandStaff <<
  \new Staff { \key c \minor ... }
 \new Staff { \clef bass \key c \minor ... }
>>
Then I declare the variables with music:
refren = <<
\relative c'' { g8 c e es4. f8 d4. es8 c2 }
\relative { r8 r4 c8 es g c c, f g b c, }
>>
episodeA = <<
  ... >>
episodeB = <<
  ... >>
And I will add this music to score block:
\refren \bar "||" \episodeA \refren \episodeB
Is this case possible? If so, how to implement it correctly, where is 
the documentation written about it? Sorry for my bad english.


You probably already know this, but in addition to the answers you 
already have received, the simplest answer for the simplest special 
case, when you only have a single voice of music, is of course:


episodeA = {c d e f}

episodeB = {g f e d }

ending= {c1}

% Pasting it together:

{\episodeA \episodeB \ending}


However, as soon as you have several parallel voices/staves in each of 
the sections, then you either could paste each full voice together as 
described above, or use any of the techniques that Valentine mentioned 
in his reply, for example.

Re: Organization of the piese part by part, not staff by staff

[Павел Буданов]

Thank you for the answers. I learned everything I needed11.01.2019, 03:37, "Saul Tobin" :Fundamentally, the data model of Lilypond is horizontal, even when you delve into the guts of how the program works (iterators, streams, engravers). My advice is to embrace that and adapt your workflow and thinking to take advantage of Lilypond's strengths, rather than fighting against it.In my experience composing with Lilypond, dividing pieces into sections like this leads to more pain later on if I decide I want something like an overlapping hairpin between the sections. Yeah, it's a little annoying to count bars in each part if I decide to add a measure or change a time signature, but it's not that big a deal if you use barchecks and one measure per line of code.Having a single variable for the music for each part to be extracted makes a lot of sense, since it keeps the composer in the mindset of what each player will be seeing.My two cents.On Thu, Jan 10, 2019 at 4:03 PM Valentin Villenave  wrote:On 1/10/19, Павел Буданов  wrote:

Greetings Pavel,
at its heart, LilyPond very much encourages «horizontal thinking»:
it’s easier to enter one melodic voice, then another, then another.

However, there are a few ways to enter music section by section like
what you’re looking for. The first one is to use \context Staff (which
can re-use an existing Staff rather than create a \new one every
time):

%%%

FirstSection = <<
  \context Staff = "voice" \relative c' {
    c2 d e1
  }
  \context PianoStaff = "piano" <<
    \context Staff = "right" \relative c' {
      2  1
    }
    \context Staff = "left" \relative c {
      \clef bass
      e2 b c1
    }
  >>
>>

SecondSection = <<
  \context Staff = "voice" \relative c' {
    a'2 f4 a g1
  }
  \context PianoStaff = "piano" <<
    \context Staff = "right" \relative c' {
      2   q
    }
    \context Staff = "left" \relative c {
      \clef bass
      f,4 g a b c2 c
    }
  >>
>>

\score {
  {
    \FirstSection
    \bar "||"
    \SecondSection
  }
}

%

The second trick you may be interested in learning, is \parallelMusic
(which allows you to enter polyphonic music with every voice at once).
Have a look at this chapter:
http://lilypond.org/doc/stable/Documentation/notation/multiple-voices#writing-music-in-parallel

Good luck!

V.
