Re: Persian accidentals (koron and sori)

[Noeck]

Dear Werner,

I am all for it and know nothing about Persian music.

One comment: When looking at Fig. 11 in your PDF, two suggestions came
to my mind. The handwritten accidentials show some less sharp edges
because the ink is flowing in the inner angles of the glyph. As you
already take the liberty to match the style of classical accidentials,
how about avoiding some sharp inner  angles by

1. filling the tiny white triangle in the sharp-like glyph (I am less
convinced)

2. making the right inner angle round (looks good to me)

I have two images attached where the additinal ink is painted in red and
in black.

Of course, this is just a suggestion.

Joram






I know, thanks.  Here you can find some glyph examples

Scores can describe what a player should think or feel even though the

You can search the list archives for "\after" a small function that can

Re: Why does -dbackend=svg -dcrop remove system-system-spacing?

[Noeck]

Hi,

many years ago, I asked for a -dcrop options for SVG for a very similar
usecase: adding SVG images to a website (a markdown extension in
particular). It was then implemented some time later and I was happy
with it (with my single line scores). It might be that Étienne Beaulé
implemented it, but that is just a guess from a distant memory - git
could surely tell.

I am writing that here, because I’d like to add that as far as I
remember, the intention for -dcrop was like Trevor explained and the
removal of inter-system white-space seems like an accident to me.

what you describe sounds somewhat similar to gridly:

I have never been in need for such an approach. Which is why I don't
know enough about gridly to describe it properly. And it is not about
spreadsheets just the time/voice-segmentation sounds similar to me. But
perhaps you can have a look at it.

But implementing a conversion from spreadsheet to a Python list of lists
is pretty straight forward, too. I would use pandas or openpyxl to read
the spreadsheet. Sth. like

import pandas as pd
pd.read_excel(filename).values.tolist()

I have doubts that I myself would like to edit it in a spreadsheet - I
just appreciate the text based approach and git too much to do that.

tl;dr: problem solved with own build of python3-poppler-qt5


I build the python3-poppler-qt5 code according to the wiki and it works
now with Fresobaldi 3.1.2 from github.

Ubuntu provides a consistent (yet very old) combination of Frescobalid
3.0.0 and python3-poppler-qt5 0.24.2. So can’t see a bug on Ubuntu’s
side. Even though it is a pity that they will ship this old version
until 2025 with an LTS-update only in 2022.

As I wanted to use a new Frescobaldi (3.1.2), I had to follow the wiki
and build python3-poppler-qt5 0.75.0 myself. This combination works now.

By the way, one of several reasons to my own Frescobaldi was that the
version from the package repository depends on lilypond which depends on
python2 as the only application on my system. (I know, I could instruct
apt to ignore it and the lilypond installer also ships with python2).

Well not the package, but the code. I looked at the github page¹ and it
seems that the Ubuntu package (0.24.2 from 2015) is very old compared to
recent releases on github (0.75.0 from 2019). Should I use 0.75.0 instead?

I looked at the dependencies of the frescobaldi package and now

The music view is there, it is empty (gray). The tools menu looks normal
and I can choose the music view there and also deselect it. The SVG view
works and shows the document (if I compile it to SVG). The PDF-document
drop down in the symbols tool bar is gray and empty.

One other piece of information: I get this warning when starting
frescobaldi in the terminal:

And the application has no icon in the Gnome menu. Could it be a Wayland
issue? Using the second variable does not change anything obvious.

No. The PDF never appears, even with the most basic input like:

{ a }

I guess, the problem is related to the fact that I did not install
Frescobaldi properly but just run the Python file. But starting the
installed version does not open up Frescobaldi at all...

PDF not shown in Frescobaldi

Hi,

when I compile a file with Frescobaldi, lilypond is invoked and creates
a PDF in the same folder as it should. But Frescobaldi does not show it.
When I go to Tools > Directories > Open current folder, I can open the
PDF there. It worked correctly with Frescobaldi 3.0.0 from the package repo.

Frescobaldi 3.1.2 downloaded from https://frescobaldi.org
(not installed via package manager on Linux)
I run it with this command:

python3 ~/frescobaldi-3.1.2/frescobaldi

Ah, lilypond-book makes sense. Because a deb-package does not provide

python2 should not result a Debian or Ubuntu deb which requires python2,
should it?

I should have said that you need to adjust this value to your needs.

You can move the InstrumentName to the left (-) and to the right (+).
Instrument names are right aligned with the left staff edge by default.
You can change that using either X-offset, padding or extra-offset.

Access Clef during after-line-breaking of ClefModifier

Hi,

I have redefined the \clef command to sneak in an override to the
ClefModifier. That works but I can't use it as a layout as it is "baked
in" the music expression.

I guess there is some "after-line-breaking" solution with a lambda
function operating on the grob (ClefModifier). But I could not find it.
I would need access to the kind of clef, the ClefModifier is attached to.


\version "2.20.0"

% this works but is redefining a standard command
clef =
#(define-music-function (clf) (string?)
   #{
 \override Staff.ClefModifier.extra-offset = #(cond
   ((string=? clf "treble_8") '(1.5 . 1)) ; exaggerated position
   ; there are more conditions in real function
   (#t '(0 . 0))
   )
 #(make-clef-set clf)
   #})

{
  \clef "treble_8"
  a1
  \clef "bass_8"
  c,1
}

% how can I know what kind of clef it is here?
{
  \override Staff.ClefModifier.after-line-breaking =

Of course. My wording was wrong here.

I made a small ly-file just to show how the accidentals with numbers

Re: A request on behalf of Turkish Music

[Noeck]

FWIW, SMuFL defines these code points and you can see the style in the
Bravura font. There is a sharp with the number 5, too.

The attachment shows, that they define a fixed glyph combination.

The code in bravura-smufl.ly uses the openlilylib/snippets¹ and it
requires the Bravura font to be installed. In the definitions.ily file,
you can also see how to use the font to print grobs (here the
Accidentals, line 372).

A combination of makam.ly and this definitions.ily should be easy to do.
But as Werner said, having them in the Emmentaler font (one way or the
other) would be better.

Your examples to keep the pedals aligned are interesting and without

Also a matter of taste and (more importantly) use case. I have a piece
at hand with very regular pedal marks. It is basically a repitition of
the same pattern. It is much cleaner to enter this with skips than in
one of the voices. (By the way: Which one? The lowest?)

So for me, the Dynamics context still needs less manual intervention but
your alignment functions are great and I'll have a look at them for
dynamics.

Re: Unwanted warnings/errors on pedals for multiple voices

[Noeck]

Hi Paolo and Kieren,

I am currently running into the same issues. I also find jumping pedal
marks irritating, even the Ped * variant. My preferred algorithm for
pedal spacing and alignment (not backed up by any notation standard)
would be this:

1. Pedal marks are vertically aligned per system
2. The staff padding is a little bit larger than LY defaults to
accommodate single lower notes.
3. The padding to notes and ornaments is very small (default)
4. If still required the whole pedal line is pushed down.
5. If single notes push it down very far (~3 staff spaces), the
alignment breaks up and only this pedal bracket is pushed down.

2+3 minimize the need for exceptions (5).

I try to achieve this manually. Typically some staff-padding does (2)
but is not enough for (4). So a separate context with spacers and pedal
marks is closer. This way, (5) is much more difficult, though.
A separate Dynamics context works quite well but it needs manual
adjustments for (5).

Examples are attached.

Joram

Ties between Fingerings

Hi,

can Lilypond draw ties between fingerings?
I can fake it by using a slur and putting it above the fingering:

  \override Fingering.avoid-slur = #'inside
  cis''-4( c''-4) r

Is that the way to go or is there a semantically correct way of
specifying ties between fingerings instead of notes?

Fingering and slurs

[Noeck]

Hi,

I am transcribing piano music and I see a lot of ugly situations with
fingering and slurs.

Lilypond seems to draw the slur and then puts the fingering on the
inside if there is space and on the outside if not. From the score, I am
reading, I deduce these rules:

- fingering above the slur at slur tips
- fingering inside the slur otherwise
- fingering is above the staff for c'' and higher notes and
  inside the staff for lower notes

Is this a general practice or just happens to be what I see here?

I can regularly switch from avoid-slur between inside and outside and
set staff-padding to ##f and revert it by hand. But can you give me some
hints how to implement the rules above? I.e.

1. change avoid-slur based on slur beginnings and endings and
2. change staff-position based on the pitch of the note?

MWE:

\relative {
  \time 3/4
  \tempo "default"
  b'4.-2( a8-1 cis-2 e-4) |

  \tempo "inside"
  \override Fingering.avoid-slur = #'inside
  b4.-2( a8-1 cis-2 e-4) |
  \revert Fingering.avoid-slur

  \tempo "what I want"
  b4.-2(
  \once \override Fingering.staff-padding = ##f
  \override Fingering.avoid-slur = #'inside
  a8-1
  % I know this looks bad, but I that is the best rule I could find
  % \override Fingering.staff-padding = ##f  % manual override
  cis-2
  \revert Fingering.avoid-slur

  a1 \bar  ".|:-||" \break   % works as expected
  a1 \bar  "||:" \break  % does not work
  a1

The bar should be as in the English docs:

I guess this is from some ancient version when barline nomenclature was
different.

Well, there is a lot more which is not up to date, examples are

I can only contribute from time to time, let's say 2 paragraphs and then

That sounds fine. You always show notes with the same pitch. It might
make sense to look at slanted beams, too. But as there is no problem
currently, I would not expect one due to the gap change.

Btw, how do you produce such a tremolo?
I know these (depending on the notehead), but how to attach one beam and

Re: Proposal: Changing tremolo beam gap implementation

Hi Torsten,

I would also expect the "gap" to be the free space between stem and beam.

In your attached image, I wonder if you have drawn the upper beam from
the inner edge of the stem only for demonstration reasons, what a gap=0
would be. The stems and beams have slightly rounded corners, haven't
they? So if the beam touches the stem, it should overlap to avoid little
notches where they touch.
In other words, while currently gap=0 is a valid choice, with your
proposed gap definition, gap should either be >0 or -stem-thickness but
not 0, right?

{
  \override Beam.gap = 0.13  # roughly equivalent to free space = 0
  \repeat tremolo 4 { a32 e' }
}

Isolated durations on rests

Hi,

is this behaviour intentional?

  \version "2.20.0"
  { r4 8 a b }

The "8" is equivalent to c'8. I think I understand what happens: the
isolated duration is given a default pitch c'.
What I would expect is that it is another rest, equivalent to

  { r4 r8 a b }

Was this just easier to implement that way for isolated durations or is
there another reasoning behind that behaviour?

I spoke too soon here. It would actually be nice to put the includes first.
Can I use fromproperty also in Scheme code? Or does the late evaluation
contradict with the usage in Scheme?

So I did another try and used the footer markup, but I can't use
fromproperty in Scheme code. This is what I tried:

\version "2.20.0"

\header { title = "Title" }
\paper {
  oddFooterMarkup = \markup \fill-line {
\null
#(if
  (string-null? (markup->string #{
\markup \fromproperty 'header:license #}))
  #{ \markup \with-url

 \fromproperty 'header:license #} "")
% the lines above should finally produce this if license is defined:

  }

Dear Aaron,

Yes, it is my intention. I want to work with strings and not markup as I

> Next, why use strings and string-append at all?

Because that is just a tiny example. I would like to create links to CC
licenses based on a license field etc.
What I am lacking here still, is how to do \with-url in Scheme or a
mechanism to show parts only under a certain condition:

\markup { "Text" ??if \license then \with-url #"url" "License" endif?? }

> Finally, \fromproperty is important as it defers the evaluation of the

Re: Function operating on header

Thanks Francisco! That's great news!

It also works across separate header blocks and even from within

\fromproperty mechanism. So this works for me:


\header {
  title = "my title"
  composer = "will be replaced"
}

% can also be included via \include
\header {
  composer = \markup { Composer of \italic
#(string-append "»" (markup->string title) "«") }
% instead of string-append, I can now work with the string
}

The order is important. The correct (working) syntax is:

\chordmode { f,,2:3.5.8/+c }

which is an f major chord with an additionall octave on top and a c,,
below. Simply adding the 8 also adds the minor 7th and adding the 5
removes the third which needs to be added again. That leads to :3.5.8

So first the colon then the slash.

Re: print copyright on every page

The default footer is this:

oddFooterMarkup = \markup {

  \on-the-fly #part-first-page \fromproperty #'header:copyright
}
\fill-line {
  %% Tagline header field only on last page in the book.
  \on-the-fly #last-page \fromproperty #'header:tagline
}
  }
}

If you redefine the footer markup without \on-the-fly #part-first-page,
you get it on every page:

\version "2.19.84"

Re: openLilyLib website

[Noeck]

Dear Urs,

it’s great that you found time for that. It looks nice and I think
MkDocs is a good choice (would have been my first choice, too).

While speaking about documentation, I very much like this approach:
https://www.divio.com/blog/documentation/

Some nitpicks from me:

- Should everyone see the "Edit this page" pencils?
   - Those links are broken for me
- If you descend into a package documentation, "Home" will not bring you
to openlilylib.org but to the page of the package. While that is
probably a consequence of your fourth bullet point, I find it confusing.
- Do you like the brown color?

While this theoretically makes sense to separate the packages'
documentation, I would run from git submodule. But perhaps your use case
is easier than where my experience comes from and you can still change
that decision later in case it makes things easier.

What do you mean by signatures?
IMHO, this makes sense for "reference-type" documentation in addition to
other parts of the documentation (cf. link at the top).

Re: \fixed

[Noeck]

What happens if you compile the file? Is \fixed just marked red or is
there an error when compiling? Older versions of Frescobaldi did not
know some commands and treat them as a warning in syntax highlighting
even though the installed LilyPond version might understand the syntax.

That being said, a completely red line usually indicates an error
reported by LilyPond. So the next question is: What LilyPond version are
you using?

Re: Titles italic format ignored

Hi,

as others said, font-name overwrites all of font-family, font-series and
font-shape. You can set the font family like this:

\version "2.19.84"

\paper {
  % define a font ‘arial’ from the font called ‘Arial’
  #(add-pango-fonts fonts 'arial "Arial"
(/ (* staff-height pt) 2.5))
}

% use the font family ‘arial’ in your markup or header markup
\markup \override #'(font-family . arial) \line {
  \bold "Bold" \italic "italic" "regular"

The SVG is the source in the sense "preferred form of modification" – at
least preferred by me :). It is created with Inkscape. I guess it could
be done in LilyPond or TeX or sth else but probably with a similar
amount of complexity (except some text replacement perhaps).
Personally, I would update it via Inkscape (and export to PDF
additionally). The cheat sheet is 8000 lines as SVG (with the line
breaks Inkscape introduces, but you get a feeling). The spacing sheet
3600 lines.

Hi Michael and Karlin,

thank you for your positive reaction. There are 3 files¹:

- “visual index”: https://joramberger.de/files/lilypond_visualindex.pdf
- spacing overview: https://joramberger.de/files/LilypondSpacing.pdf

The cheat sheet is also available in other languages (and as SVG)²:

>> Why isn't this part of the official docs?

I once tried to get them in an appropriate place in the official
documentation. But they were not accepted. For the cheat sheet, main
objections were:

- not source code (even though SVG is an open and text based format)
- needs updates for new versions (well, those basic things did not
  change for at least 7 years now and even if they did…)
- does not fit into the texinfo documentation creation process (ok)

The case of the spacing overview is similar. The visual index is created
from a LilyPond source code. If I (or someone) finds a way to create a
clickable SVG file from it, one could include it into HTML and make it
blend much better into the/a documentation website.

Re: Positioning of a tiny voice

Hi Kieren,

unfortunately not, because the "music" voice should behave like a

Positioning of a tiny voice

[Noeck]

Hi,

I would like to add small notes into an already populated staff.
It is the right hand of a piano staff and I don’t want real voices with
their shifts. The tiny font size distinguishes the "upper" voice
already. It should have the least impact possible on the "music" voice.

Here is one example measure:


\version "2.19.84"

upper = \relative {
  \tiny
  \stemUp
  s4 b''
}

music = \relative {
  \key e \minor
  \time 2/4
  b'8 16 c' 8 16 b'
}

\new Staff << \upper \music >>


How to move the b'' exactly on top of the chord below?
What to do about this warning?

warning: this Voice needs a \voiceXx or \shiftXx setting
  b'8 16 c' <
 b, e g b>8 16 b'

That was my intention. LilyPond is one of the few programs still using a

Re: "Mensurstriche" (barlines between systems) and Repeat signs.

[Noeck]

Hi,

I probably don't understand all the implications and I am certainly not
suggesting to change the function signature. But while we are at it:

A definition is usually “name” = “the thing to be defined”.

In the current \defineBarLine function, I always wondered why the first
argument contains a real barline and not just a name for it:

\defineBarLine ".|:-||" #'("||" ".|:" ".|")

The first argument mixes barlines and a suffix. ‘.|:’ is a real bar line
and the ‘-||’ part is a name extension. In order to cleanly separate the
name and the definition, this would me much clearer:

\defineBarLine "myname" #'("||" ".|:" ".|:" ".|")
i.e. "name" #'(start middle end span)

"name" could still be ".|:-||" – or anything else.

Re: staff order

Dear Sean,

the Staff needs to start with a capital S: \new Staff
LilyPond is case-sensitive. That’s all.

Two other points:

1. You have some arbitrarily placed braces. I’d suggest to use them only
where they are needed.

2. Are you really using LilyPond 2.14? That’s really old. I’d suggest to
install a newer version (2.18 "stable" or a also reasonably stable
"development version" 2.19).

Here is your code such with the correct Staff:

\score {
  \new StaffGroup <<
\new Staff {
  \time 3/4
  \key ees \major

\new Staff {

I think \stemUp/Down has its place as a fine tuning not a replacement
for voices.

Here is a snippet where I actually think it is a reasonable choice to
use \stemUp and \stemDown:

\version "2.19.80"

\relative {
  \key c \minor
  \voiceOne
  \stemDown c'16\p^( es fis g \stemUp as\< g fis g \!
  es'\> d c g\! as[ g] \stemDown fis g) |
}

(First voice and first measure of Rachmaninoff, op. 23 No. 7.)

It's piano music and I already use 6 voices to represent the
"voice"-structure of the music. But sometimes the notes of one voice are
played by the other hand and that is indicated by the stem direction.
All other directions are kept (slurs, etc.).

Validity check for lilypond files

[Noeck]

Hi,

is there a way to check the validity of a .ly file?

I am thinking of a syntax check – so basically if the parser/lexer can
read it. It should (a) be quick and (b) not produce any output (could be
deleted as a last resort).

Is there something in python-ly that does that? It looks like the
Frescobaldi auto-engraving only runs if the input is valid.

I guess to check everything, I would have to run lilypond on it and see
if there are any warnings or errors. But I am willing to have less
coverage if I can get the result faster.

Thanks in advance for any hints.

While you can omit accidentals with the first line, you cannot set the
stencil to true. This prints a warning:

The right thing to do is to revert the override:

  fis
  \override Accidental.stencil = ##f
  gis
  \revert Accidental.stencil
  cis'
}

Or equivalently in more recent versions:
