Thank you David Olson for copy-editing!

The remaining two posts will take more time because the underlying stuff 
will have to be tidied-up.

You could do something like this:

Nice! This should be added at least to the snippet repository if not to 
vanilla LilyPond. I don’t know whether many people would use it but it’s 
a small addition and AFAIK this feature is present in every other 
engraving software I know …

I like the highlighting idea! Is it compatible at all with 2.18.2 ?

It seems not to be: http://lilybin.com/166vv7/1

While I would strongly suggest that you update to the latest development

as very stable, this would work with 2.18.2:

\epsfile

[Martin Tarenskeen]

Hi LilyPonders,

I am experimenting with the \epsfile command to include various pictures 
in my score. 
http://lilypond.org/doc/v2.19/Documentation/notation/graphic.en.html 
describes:


 \epsfile axis (number) size (number) file-name (string)
Inline an EPS image. The image is scaled along axis to size.

I don't quite understand what "axis (number)" means and how it works. I 
can reproduce the examples, using my own images, but would like to 
understand the values better.


Related issue: When using frescobaldi the syntax help and 
autocompletion balloon gives "\eps-file" instead of "\epsfile". A little bug?

Thanks, "ambitus" works great for a start.
Next step would be automatic checking if the ambitus is within
an instrument capability, which the coloring hint by Aaron should
help with, if I handle to make it work :)

Seems so, yes. IIUC it has been \epsfile for at least a very long time

X and Y are speaking variable names for the numbers 0 and 1 (which you

#(display Y)

), hence the docstring.

... which is of course possible but somehow surprising. AFAIK 
Frescobaldi's "knowledge" about LilyPond's syntax is retrieved 
automatically, although I don't recall whether that involves parsing the 
documentation or running LilyPond itself.


What *is* known is that Frescobaldi's autocompletion works on the 2.18 
syntax because it's official policy to support the "latest stable 
release". We have agreed upon the idea that it would be better to 
support both the current stable and development releases but so far 
noone has found the time to implement that.


It should not be *that* complicated, so any volunteers are encouraged to 
step forward ;-)

Re: \epsfile

[Andrew Bernard]

I think the doc is a bit misleading. Axis is technically a number, but 
it's really #X or #Y, and the following number is that the image is 
scaled along the specified axis to size, a number.


\markup {
  \general-align #Y #DOWN {
\epsfile #X #20 #"context-example.eps"
\epsfile #Y #20 #"context-example.eps"
  }
}

The example is clearer than the text.

It would be nice to include more debug annotations within LilyPond.  
If I am not mistaken, we currently have the following options:


  \paper { annotate-spacing = ##t }
  #(ly:set-option 'debug-skylines)
  \override [Non]PaperColumn.stencil = #ly:paper-column::print

For the future, we could add support for these cases:

- Plotting curve control points.
- Visualizing the extents and origins of grob stencils.
- Indicating the relationships between grobs (i.e. parents, children, 
siblings).


Are there other annotations that folks would find helpful? Providing 
there is enough interest in such support, we should open a ticket for 
tracking the work.



Frescobaldi also offers the following options (in the Layout Control Tool):

- coloring voices with explicit \voiceXXX
  (unfortunately implicit ones in polyphonic settings are not possible)
- coloring explicit directions with ^ or _
- print the grob names

What I'd find interesting in addition would be:

- visualizing extra-offset (by plotting a line between the final and the 
original refpoints)
- visualizing *other* properties of bezier curves, for example angles 
and ratios
  (those that can be set with \shapeII). These are of course not 
available as properties

  but would have to be calculated.
  The results should be printed in a semi-transparent (?) rectangle 
overlaying the score
- in a similar vein there could be a more generic function to "debug" a 
grob by printing
  selected property values on top of the score (something like a ballon 
text, but overlaid)


These visualizations should also be possible to switch on and off in the 
course of the document to just apply them to a selected range or even a 
single item.

The thing is I'm writing multiple scores with the same parts
replicated (some with all 3 voices, some with just 2 voices)
so I'd like to avoid the duplication of ranges. A range is
specific to an instrument so I'd like to specify that in the
header for each instrument, reguardless of score...

Actually, I'm thinking I'd build a database of available ranges
for instruments and players / singers, so that when a score
is intended for playing by known people I'd just reference
their names in the score...

Why not put it in the underlying "input" then?

You could even define a shortcut for this:

Didn't I reply to your inital question, asking for more version details? 
Sorry.


I can't look into the details right now, but the version of the code 
included in Frescobaldi 2.20 obviously isn't compatible with LP 2.19.52. 
We fixed that at some point, but I think that will only be easily 
available with the 3.1 release we are currently planning.


However, you can look into 
https://github.com/openlilylib/oll-misc/tree/master/layout/display and 
try integrating the code in the control-points.ily file. Maybe that 
works for you.


And I suggest updating LilyPond to 2.19.83 if there is no specific 
reason not to do so (although that will probably not help you with the 
issue at hand).

If LilyPond knew that there was a collision it wouldn’t engrave it that 
way so IMO that’s a bug. Without knowing about a collision LilyPond

I sort of solved the problem without looking at the grob details, so the need

repeat in alternative

[Sandro Santilli]

Is there a way to obtain what I'm finding in this paper sheet ?
http://strk.kbt.io/tmp/repeat-in-alternative.png

It's basically a repating section starting within an alternative
section...

Two options here:


\version "2.19.83"

{
  \time 3/4
  \repeat volta 2 { a'4 b'2 }
  \alternative {
{ g'2 r4 \bar ":|.|:" }
{ c''2. }
  }
  { b'8 a' g'2 \bar ":|." f'2. \bar "|." }
}

{
  \time 3/4
  \set Score.repeatCommands = #'(start-repeat)
  a'4 b'2
  \set Score.repeatCommands = #'((volta "1."))
  g'2 r4
  \set Score.repeatCommands = #'((volta #f) end-repeat start-repeat 
(volta "2."))

  c''2.
  \set Score.repeatCommands = #'((volta #f))
  b'8 a' g'2
  \set Score.repeatCommands = #'(end-repeat)
  f'2. \bar "|."
}


Note that using repeatCommands handles the bar line types for you, 
although it opts for ":..:" as the double-sided repeat.

It’s in fact a second alternative (second volta) in a single repeat.

Nope, I tell a lie.  Here's a third:


{
  \time 3/4
  \repeat volta 2 { a'4 b'2 }
  \alternative {
{ g'2 r4 }
{ \repeat volta 2 { c''2. b'8 a' g'2 } }

}


This one has the volta bracket extending further.

Re: How to color objects that cause collision

Well, you would need to define what exactly _is_a collision?
Printing one grob above the other?
No, can't be a sufficient condition.

Look at this code:
{
  \override Stem.color = #red
  \override Stem.layer = -1000
  b8[
  \override Stem.layer = 1000
  b8]
}

Obviously the Clef collides with StaffSymbol, as well as the TimeSignature.
The NoteHeadcollides with the LedgerLine and Stem.
The Stem collides with the Beam, which collides with the StaffSymbol.

Ofcourse all this is wished.

How to limit to unwished things?
And if unwished things happens, then because Grobs are not aware of each
other. Making it difficult to get something like a "collision yes/no"-info
out of LilyPond

I don't see how to solve.

Re: Mac OS 10.15 Catalina

[Allan Kinnaird]

So here I am (as I see it) :
My current version of Lilypond is not going to work on my Mac if I upgrade to 
Catalina (v10.15) because of an incomprehensible licence impasse between GNU 
and Apple.
Hans Åberg has provided an installable package ( 
https://www.et.byu.edu/~sorensen/lilypond-devel-2.19.83_2.mpkg 
 ) which runs 
as 64-bit on Catalina. It appears that it has problems with convert-ly but is 
otherwise OK. (And Frescobaldi users need to point Frescobaldi preferences 
towards the right version of Lilypond.)
I have downloaded Hans’s file and tried to install it. Unfortunately the 
installer blocked the process, requiring that the OS be 10.15 Catalina - I have 
to go for Catalina before I can test for problems with it.
So, to continue using Lilypond, either I have to stay forever on v2.18.2 and 
have my computer stay forever on OS 10.14, or just go for Catalina, run Hans’s 
installer, and accept what disasters then ensue. (Hans seems a pretty good guy, 
so with luck there won’t be many!)

Not quite.

You can stay on Mojave, and continue to run LilyPond as a 32-bit binary in all 
of the current versions.  Because we have a darwin SDK that is at least tacitly 
approved by Apple, we can build 32-bit.  We just can’t build 64-bit.

If you want to use Hans’s installable port, you’ll need to jump to Catalina.

One possibility that could avoid the potentially risky jump to Catalina would 
be to get somebody to follow Hans’s MacPorts build instructions on Mojave, and 
verify that it works on Mojave.

But we have enough people saying Hans’s port runs on Catalina that I don’t 
think it’s much of a risk, if all you’re worried about is LilyPond.

You could also run LilyPond under Linux in a virtual machine on your mac.

Extract measures with function

[Michael Käppler]

Hi all,
is there a way to extract some particular measure from a voice through a
music function?
Like

bla = { c4 d e f | d e f g | e f g a }

\someMagicFunction #2 \bla -> d e f g
I would be very happy if someone could point me in the right direction.

Thanks,
Michael

Re: Mac OS 10.15 Catalina

[Mario Bolognani]

After having installed Catalina I tried to install Frescobaldi plus LilyPond 
(the 64bit version provided by Hans  Åberg) but, while Frescobaldi 2.20 64bit 
apparently runs normally, I had no success with LilyPond… I am a musician not a 
developer so I’m not able to understand the reasons of this failure. So I am 
back to Mojave and the 32bit versions of Frescobaldi and LilyPond. Waiting for 
good news on the subject.

Best,
