Sorry; I retract this email.  It's rubbish!  All that does is invalidate the

I read in the manual:

Manual beams

In some cases it may be necessary to override the automatic beaming
algorithm.  For example, the autobeamer will not put beams over rests or
bar lines, [...]

So the behavior is known, documented, and deliberate.

I thought you were going to write something like this.

1. The report was (supposed to be) about the missing beam over the first 
two quavers, which are not separated by a bar line. So this is not 
covered by the doc excerpt above.
2. If we accept this as a limitation, then it is a severe one IMO. The 
only sensible way to allow mid-bar line breaks is adding a parallel 
track inserting these invisible bar lines in every measure, and if this 
breaks autoBeaming, then there is no way at all. Adding manual beams for 
the entire piece is too much work and completely undesirable.


I’m not speaking about cases like

<<
  { \time 3/4 s4 \bar "" s \bar "" s }
  { 8 8 8 8 8 8 }
>>

yet, where the beam should ideally extend over the whole measure except 
if there is a line break…

lilypond-book: "external" fonts and --pdf option problem

2015-12-07 Thread Dmytro O. Redchuk

Hello bug squad, hello list,

I've found a problem with this "book":

% test.lytex:
% 8<
\documentclass{article}
\begin{document}
\begin{lilypond}
  \include "improviso.ily"
  { c''4 }
\end{lilypond}
\end{document}
% 8<

I want lilypond to engrave it with "improviso" font,
https://fonts.openlilylib.org/improviso/ --- I have set it up, it's
ok.

Now: lilypond-book does well without --pdf option:

$ lilypond-book -I ${HOME}/lilyponds/local-includes --out=out test.lytex
$ cd out
$ latex test && dvips -o test.ps test.dvi && ps2pdf test.ps

Now I have the desired result.

But it fails when I want to do it for pdflatex:
% 8<
$ lilypond-book -I ${HOME}/lilyponds/local-includes --out=out --pdf test.lytex

Layout output to `b5/lily-09c4cef9.eps'...

Writing `/home/dor/tmp/ly-test/out/test.tex'...
% 8<

Now I have pdf containing a score with no clef, key signature and notehead.

I've attached png files produced by
$ convert -density 150 -1.eps -flatten -1.png
for both ways, with and without --pdf.

Is this an issue? How to work around?

Thank you!

I have no any problem with lilypond-book and Emmentaler (lilypond's
default) font. With or without --pdf, really.

I am sorry to be unclear. That \include imports the stylesheet for
improviso font (https://fonts.openlilylib.org/improviso/, an alternate
font for lilypond).

So, without --pdf I have nice result, with --pdf I have a score(s)
with "improviso-related" objects missed.

Hi all,

In the file lily/beam.cc, lines 231-232, we find the following comment:



We want a maximal number of shared beams, but if there is choice, we
take the one that is closest to the end of the stem.

I believe the maximal number of shared beams is indeed necessary, but the
problem is to always take the beam that is closest to the end of the current
stem, since I think this is what leads to the staircase effect. Probably a
better algorithm would be to consider the beam closest to the end of the
stem at the start of a subgroup. Basically, if a beam is added to a subgroup
above the initial beam(s), then all others must be added in the same
direction. Once we are back at the same number (or less) of beams as
initially, then the next group can be created either up or down once again.

E.g. in the image below, the beam for the fourth note in the lower staff
should have been an extension of the bottom beam of the third note, since
the previous subgroup was added above the initial beam:



One more example showing how the subgroups should have been beamed:



I also would like to offer a small bounty to get this fixed: I can pay 30
EUR to anyone who is able to fix this until February 2016. I know that
giving a deadline for a bounty isn't really the most elegant thing to do,
but this issue is greatly affecting my final work for my master's degree and
I must have the score ready by the end of February :(

Cheers,
Gilberto

I used your command, without the include (obviously as I don't have it)

$ lilypond-book out=out --pdf test.lytex


Then I cd into 'out' and run

$ texi2pdf text.texi

The resulting PDF shows me the clef, key signature etc.

So it seems - with my very limited experience -  to be something local
to your environment (or perhaps your 'include').
