Re: Getting Lilyjazz fonts back in business

[Jan]

Hi Mark,
Indeed, I missed the supplementary files when I manually installed the style. 
This did the trick.
Thanks a lot for your clear and prompt reply.

I have, but thanks for the suggestion.  MKVIDEO is not nicely
distributed (no git repo) so I didn't have a good look.

The problem with every lilypond video generation solution I've come
across:

ly2video
lilypond-html-live-score
LilypondToBandVideoConverter [1]
MKVIDEO

and even this unreleased one:

https://www.youtube.com/watch?v=JqwrqhPQIWQ

Is that page transitions are abrupt.  It's hard to follow the music
when the page transitions and you can't read ahead.  For my intended
use, it's not good enough.

I know that ly2video can scroll the music and leave the cursor
stationary, but that's not a good solution to this problem either.

Seeing two lines of music at a time is the right solution for me: the
current line and the next line.  At least on my phone's screen.

Really lilypond-html-live-score is quite impressive.  I like how they
use svg elements instead of png.  If the page would scroll
automatically while the music was playing it would very useful to me.
 At the same time, I would prefer a video to an html page.  It's easy
to slow a video down to learn more difficult parts.

However, ly2video seems to be the only solution that will take a
beatmap file to sync up audio with the notation.  It's called midi-
rubato and this is crucial for the kind of scrolling video scores that
I'm interested in making.

lilypond-html-live-score uses an engraver with /consists like event-
listener.ly. ly2video uses the after-line-breaking callback.

The problem is that the line breaks and page breaks don't have such a
callback.

Having a closer look at mkvideo, it's using after-line-breaking as
well.  But I noticed something interesting:

\paper {
#(define (page-post-process layout pages)
 (after-pb-processing layout pages))
}

earlier, after-pb-processing is defined.  So I copied that definition
with my own alteration:

#(define (after-pb-processing layout pages)
(format #t "\nafter-pb-processing"))

I ran lilypond.  There were no complaints and after-pb-processing did
print at the very end.  Once.  There are two pages though so I expected
to see it twice.

I don't know how I missed page-post-process before.  The documentation
says:

page-post-process (procedure)

If this function is defined (within the \paper block), LilyPond uses it
to post-process pages, for example, to extract the table of contents
and writing the information to an auxiliary file.  The call happens
after page breaking has been performed.

The syntax is
#(define (page-post-process layout pages) ... )

It would seem that page-post-process is called after all the page
breaking is performed.  I need something called when each page break is
performed.

I had a look at where page-post-process was used, in paper-book.cc, but
I didn't see anything else.  By the time it's at 'book' it's probably
too late.  I found page-breaking.cc which looked promising, but there's
no callback defined in there.  And the comments indicate that the page
chunking code is done before any drawing.

I also took a look at LilypondToBandVideoConverter, but it's pretty
complicated.  Ultimately he's using /consists with engravers too.
 Nothing about page breaks.

Unfortunately another dead end, but I appreciate the reply nonetheless
Karlin.

Thanks,
Stef

Re: Getting Lilyjazz fonts back in business

[Mark Probert]

Hi, Jan.

There are four elements to making lilyjazz work. These are, in script form,

  sh "cp lilyjazz/otf/* #{lilypond}/#{REV}/fonts/otf"
  sh "cp lilyjazz/svg/* #{lilypond}/#{REV}/fonts/svg"
  sh "cp lilyjazz/stylesheet/* #{lilypond}/#{REV}/ly"
  sh "cp lilyjazz/supplementary-files/**/*.otf #{lilypond}/#{REV}/fonts/otf”

I would guess you need to copy the supplimentary file otfs. This are for the 
chords and text

HTH

 ..mark.

clefs, time signatures, and key signatures

[Werner LEMBERG]

Folks,


please have a look at Merge Request 2188 and comment there on how to
proceed with the new distances between clefs and time signatures,
together with the new distances between clefs and key signatures.

  https://gitlab.com/lilypond/lilypond/-/merge_requests/2188

The question is whether the new distances should be based on the
widest standard clef glyph (which is the alto clef, and which is done
currently in the MR), or whether they should be based on the most
common one, the treble clef.

I looked into the code and there is an after-line-breaking in system.cc

  (void) g->get_property ("after-line-breaking");

This is used in a similar way to other places I see after-line-breaking 
 used, such as haripin.cc.  So I presume this get_property() call has a
side effect of running scheme code (ie. a callback).

That means:

\layout {
  \context {
\Staff
\override System.after-line-breaking = #printPage

should work.  And it doesn't.  I tried \Score context, no context, and
even \Voice context.  None of them printed anything.  If I'm missing
something about how this works, I can't see it.

Getting Lilyjazz fonts back in business

[Jan]

Dear Lilypond users,
I’m trying to use lilyjazz for a jazz lead-sheet, in order to reproduce the 
hand-written style. However, the fonts do not show up as they should, cf. the 
examples for the lilyjazz style. For example, this is a snipped of the 
AllOfMe.pdf 

 example provided at GitHub :



Compiling the AllOfMe.ly 
 
code with lilypond 2.24.3 (after some tweaking to get rid of a deprecated 
syntax) leads to the following:



The notes are correctly reproduced, but the chords and text are using the

the required “ily” styles are found and the fonts are installed where they 
should. 
Any help would be greatly appreciated.

Re: spacing puzzle

[Kieren MacMillan]

Hi David,

Have you looked at all the spacing parameters?
https://lilypond.org/doc/v2.23/Documentation/notation/flexible-vertical-spacing-paper-variables#list-of-flexible-vertical-spacing-paper-variables

In particular:
top-system-spacing
the distance from the top of the printable area (i.e., the bottom of the top 
margin) to the first system on a page, when there is no (title or top-level) 
markup between the two.

Hope that helps!
Kieren.

spacing puzzle

[bobr...@centrum.is]

I have a situation where I have too much music for one page and not enough to 
fill two pages.  My desired solution is to split the material roughly 50/50 
between two facing pages.  Each page would be filled approximately 1/3 but I 
want that 1/3 centered top to bottom.  I can achieve that by tweaking the 
margin sizes but that pushes the page number down the page as well.  I want the 
page numbers up near the corners.  Isn't there a way to "push" a score down the 
page like this?  I need it to happen on the other page as well.

Thanks,

David

It isn't much of an explanation, but in
http://lilypond.org/doc/v2.25/Documentation/notation/lyrics-and-repeats#index-_005cskip-1
is the line Note: do not use an underscore, _, to skip notes – an
underscore indicates a melisma, causing the preceding syllable to be
left-aligned.
A bit terse, to be sure. But mentioning an alignment issue I've always
stayed with using \skip to skip over a note, and only used _ when it really
was a melisma not explicitly notated in the music (such as a tie or a slur).

But the opportunity is missed on these pages, the first of which actually

This was the first time I'd seen the use of "" for something like this.
I'll have to keep it in mind. And looking at those two snippet pages you
linked they make it seem like all three options are equivalent. Yet in the
NR page I linked it says they are different.

Well, I guess the important bit is you found something that does what you
need, and does it in a way that you're okay with.

Re: Centering a word before a gap in the lyrics

Sure. Just use a skip. Like so:

And now I discover that "" will do the same - which makes it doubly curious 
that " " does not.  "" is a lot more elegant than \skip1 as well!

Re: Centering a word before a gap in the lyrics

[Paul Hodges]

I should have tried that again; but I've tried it in the past and it hasn't 
seemed to work.  There must be some other subtlety involved; scores converted 
from Music XML use \skip1 for melismas...  I guess I haven't fully internalised 
the various options for lyric placement.

Paul

Sure. Just use a skip. Like so:

\version "2.25.10"

wordsA = \lyricmode { centred centred centred }
wordsB = \lyricmode { centered \skip 1 centred }

\score {
  \new Staff <<
\new Voice = "vvv" { r2 c'2 g'2 c''2 }
\new Lyrics \lyricsto "vvv" \wordsA
\new Lyrics \lyricsto "vvv" \wordsB
  >>
}


[image: image.png]

One thing to keep in mind - \skip when used in lyrics goes by notes, not
beats. So \skip 1 will skip one note, not an entire 4 beats. If you want to
skip multiple notes in one go (such as dealing with alternate endings with
multiple verses) something like:
\repeat unfold 15 { \skip 1}
comes in handy. A bit more on using \skip can be seen here:
http://lilypond.org/doc/v2.25/Documentation/notation/lyrics-and-repeats#index-_005cskip-1

Centering a word before a gap in the lyrics

Consider the following:

wordsC = \lyricmode { justified " " centred } 
wordsC = \lyricmode { centred \once \override Lyrics.LyricText.color = #white 
"." centred } 
\score {
  \new Staff <<
    \new Voice = "vvv" { r2 c'2 g'2 c''2 }
