Re: Frescobaldi issue 16: .ly is missing by saving

You are the only one so far reporting that .ly is not automatically 
added.

Maybe it's because you are using an older version of KDE Plasma.

I'm running MXLinux 21.3, based on Debian 11.7, KDE Plasma 5.20.5.

I'm wondering if we can close this old Frescobaldi issue:

Can you please report what happens in other OSes and desktop

Re: frescobaldi themes

Ok, I see now.
Themes are usually desktop themes. In this case we are talking about 
the color schemes of the Frescobaldi editor.


No way to install them at once, according to:
https://github.com/frescobaldi/frescobaldi/issues/1157

I think that Frescobaldi should include at least one dark scheme 
besides the default light one.

I have read something about using tags, but I don't know how should I
use them in my file, which by the way is this:


Don't use tags.

Just use one variable name (say, music) for the \relative block and 
another variable name (say, chords) for the \chords block.
Then call only music in the score block for the singers; and music + 
chords in the score block for the guitar player.


You can find many examples in the documentation about using variables.

Where is actually the best place to post about Frescobaldi support

The Frescobaldi mailing list is the best place. And I would avoid 
crossposting.


The short answer is: as David wrote, the default url is 
http://lilypond.org/doc/stable
This is currently redirecting to the old stable, because LilyPond 
.htaccess file was not updated. There's an open MR here:

https://gitlab.com/lilypond/lilypond/-/merge_requests/1815

As soon as it's merged and uploaded to lilypond.org, Frescobaldi should 
show 2.24 manuals.


The answer to the other questions is more complex. We are working on 
it... I will reply to your question in the Frescobaldi mailing list.

Dear all,

I have a large repository of scores which are currently being built 
as eps documents using the following command:


lilypond -E -dno-gs-load-fonts -dinclude-eps-fonts file.ly

This command, up to version 2.22, generates a single eps file 
(file.eps) trimmed down to just the size of the score.


I recently upgraded from lilypond 2.22.2 to 2.24.0 and the same 
command now produces a full-page output. After searching the lists 
and the documentation, I understand that I have to set 
'use-paper-size-for-page' to false in order to get a trimmed down 
output, but I do not understand how to get a single eps file.


I have tried different combinations of command line args. I am only 
able to generate two output files (file.eps and file-1.eps), both of 
them identical and trimmed down, with the following command:


lilypond -E -dno-gs-load-fonts -dinclude-eps-fonts 
-dno-use-paper-size-for-page demo.ly


Is this how it is supposed to work? Why is lilypond generating a 
second identical file with -1 suffix?


I could easily remove the second file (file-1.eps) in my build chain, 
but I wonder if I am missing something.






There was a similar discussions last month:
https://lists.gnu.org/archive/html/lilypond-user/2022-11/msg00047.html

In your example I would add a \pageBreak to get a better understanding 
of what lilypond does.
I cannot open EPS files currently, but as far as I can see from the 
file manager thumbnails the first file is the two page file, while 
-1.eps and -2.eps are the single pages. They are different:


$ ls -lh *.eps
-rw-r--r--. 1 fede fede 157K 29 dic 14.40 demo-1.eps
-rw-r--r--. 1 fede fede 156K 29 dic 14.40 demo-2.eps

I think you are right and we should probably open a new issue.

Since C059 does not have a glyph for this character, Fontconfig
automatically substitutes some font from the system that does have
this character, according to LilyPond's font configuration file
and the system-wide configuration file.

If you run LilyPond in an isolated environment, it needs to contain
some font with this character, visible by Fontconfig.


I used your minimal example to test it and I found out that I was 
missing the font everywhere, not just in the container. I guess the

I've now installed in my home a FreeSerif font and everything works

Frescobaldi hasn't run on some flavours of Linux properly for two or
three years.  I think it stopped working around CentOS 7.9 and doesn't
work correctly under AlmaLinux.  The flatpack version won't run
correctly either, so beware!



I guess that the flatpak version is not working as you expect because 
you're missing some knowledge about flatpak.

Yes, it currently bundles 2.22.2 and 2.23.7.

So you simply have to open this file on your local Frescobaldi

Not enough. This is also needed, I think:

Hard to tell by looking at your attachment.
I suggest you write a minimal example to show the problem.

My guess is that in this situation you should:

- place the music/variables in some .ily files (to be included) with no 
\score or \header blocks
- use .ly files to create a single file and another .ly file to create 
the book. Each of them will include the needed .ily files and use 
\score and \header blocks.

There's no standard directory. Just use what you want and then use

On linux, there seems to be no equivalents, at least as far as I can

~/.local/share/lilypond would be it, but it is not created at 
installation time. Is there an environment variable that could be 
set? The docs make reference to LILYPOND_DATADIR, but that seems to 
indicate the global location, as far as I can tell from the following 
description:


LILYPOND_DATADIR
This specifies a directory where locale messages and data files are 
looked up by default, overriding locations defined either at 
compile-time or computed dynamically at run-time (see Relocation

The directory should contain subdirectories called ‘ly’,

Locale refers to localization, i.e. translation files (PO files).

You likely have wrong permissions in some directory in /var.
The error occurs when trying to install the first dependency.

Check /var/tmp.  I have:

$ ls -lhd /var/tmp
drwxrwxrwt. 1 root root 3,4K 6 nov 21.50 /var/tmp

Another possibility is that you don't have enough disk space in /var. 
But this is just a guess, as it implies a wrong error message from 
flatpak.

Re: Frescobaldi+LilyPond flatpak package now available

[Federico Bruni]

Hi Martin

Perhaps you added the flathub repository as root using the --user 
switch? (wrong)


Can you paste the output of this command both as root and as normal 
user?


 flatpak remotes

I have this as normal user:

$ flatpak remotes
Name Options
flathub system
flathub-beta user

Did you read this page?
https://docs.flatpak.org/en/latest/using-flatpak.html#system-versus-user

You shouldn't be root to install any flatpak application. I can't 
remember if adding the repository at system level requires root 
privileges.
In a nutshell, if you add a repository using the --user switch, any 
application installed from that repository will be installed at user 
level and available only to that user; otherwise the default is system 
level.

Hi Federico,

I welcome this since I've been having problems with Frescobaldi under 
both CentOS 7 and 8 for a while.


I followed the setup guide on the host CentOS8 machine and downloaded 
the flathub repository file.  First problem: I had to be root to 
install it - I thought flatpak was meant to be at user level?


I then installed Frescobaldi (using cut-and-paste).  If I tried to 
run it as a user I got the message: "error: 
app/org.frescobaldi.Frescobaldi/x86_64/master not installed".  As a 
test I tried running it as root (I know, bad practice) and the window 
opened, but then hung and would not die.


Any suggestions?

You are using pip2 (python2) installed in ~/.local, but you're trying 
to install a py3 wheel.
pip2 install seems to try to install under /usr/local by default¹, but 
it won't work unless you use sudo.



I would try:

pip3 install --user setuptools


¹ pip3 is smarter and doesn't need the --user switch if called as 
regular user, see below:


$ pip -V
pip 20.2.2 from /usr/lib/python3.9/site-packages/pip (python 3.9)
$ pip install setuptools

Hi Martin

I improved that doc page two years ago, but reading it again now I see 
that it would need a general rewrite.


First of all, how did you install Atom? It's a regular distro package 
(like .deb or .rpm)? Or maybe a flatpak or similar? Did you check if 
the atom binary can be found? Type this in a terminal:


 which -a atom

Are you running lilypond version 2.20? If so, it's Ok.

The environment variables are usually defined in ~/.profile, ~/.bashrc 
or ~/.bash_profile.

Check which files you have already with:

  ls -a ~

I'm on Fedora 33 and I see .bashrc and .bash_profile.
I'll use .bash_profile and add this line:

export LYEDITOR=gedit

(I don't have Atom installed)

Then reload the file and check that the environment variable is 
detected:


$ source ~/.bash_profile
$ echo $LYEDITOR
gedit
$ env | grep LYEDITOR
LYEDITOR=gedit

Add the lilypond-invoke-editor.desktop file as described in the docs.
Now point-and-click should be working. If it doesn't, close the desktop 
session and start a new one, then try again.

 Instead of using \pageBreak (within the music input), you may

 the line and page breaking with two different \paper blocks, one for
 the part and one for the score (using \include).

That number changed from 116 to 90 and then 101.

There was a comment explaining that number:

(TexLive is the biggest one).


Maybe packagers are worried that a new user might complain that 
Frescobaldi can't do anything.
Perhaps Frescobaldi might check on startup if lilypond is installed and 
warn the user if it's not. Looks like a viable solution on Linux and 
Mac, but maybe not on Windows?

italian list or forum

[Federico Bruni]

This is a message for the italian users subscribed to this mailing list.
Some years ago I asked if anybody were interested in creating an 
italian mailing list. We were just three :-( so I gave up:

https://lists.gnu.org/archive/html/lilypond-user/2011-12/msg00653.html

As I'm seeing more and more italians here (and also on Frescobaldi 
mailing list), I think it's the moment to create a new italian 
"community place".

Please let me know if you are interested.

What would you suggest to use?
Some options:

1. Mailing list on gnu.org (as this one)
Pro: supported by GNU project. We are confident the archive of messages 
will remain.

Con: no web interface; "old-fashioned" archive with poor usability.

2. Google group
Pro: can be used as a normal mailing list as well as a forum on the 
browser.
Con: Google might dismiss it one day; I'm not fond of being logged in 
with a google account with my browser, so I would use it as a mailing 
list.


Other options?

I'm for 1.

Let me know your thoughts.

Ciao

Based on Jerry's suggestion I've done a little experimenting. Using a 
structure like this:


\book {
\bookpart {\include "O-Welt-ich-muss-dich.ly"}
\bookpart {\include "O-Welt-ich-muss-dich.ly"}
}

does produce scores in sequence with headings, etc. in place, but the 
music processing is full of errors and the output is nonsensical (see 
attachment). Can someone explain to me why this approach doesn't 
work? I thought that anything in a \bookpart block should be 
independent of everything around it, is that not the case? I even 
tried it with multiple \book blocks, but that produced nothing at all.


IIRC the reason is that you cannot include, within a bookpart, a file 
which contains top level expressions.
This means that, even if you remove the top level expressions (such as 
\score), in any case you'll need an extra file to produce the PDF of 
the single piece.


I usually follow this strategy:

- Piece-Name.ily: file containing only music variables (doesn't produce 
any output), including a variable for the \score block. You'd better 
use variable names which are unique within your project.
- Piece-Name.ly: here I include above file and call the \score 
variable, to print a single PDF.
- If the piece is part of a collection, the collection.ly file will 
include only the .ily file and call the \score variable.

I don't have any experience with highlight.js.
Some years ago I started writing a Pygments definition for LilyPond but 
then I gave up or simply forgot about it.


The Sublimetext and Atom packages might be useful as a reference, but I 
guess that highlight.js will need its own syntax so you'd better start 
from scratch.


The problem with syntax highlighting is maintainance. LilyPond syntax 
changes and a manually compiled list must be updated manually for every 
new stable release.

Is there a way to get durations off a MIDI keyboard in Frescobaldi?


No.

If you use current master, you can type the durations first, e.g.:

s2 s4. s8

Frescobaldi with rumor appears to meet his needs, except for the fact

Frescobaldi 3 (without Rumor) also supports MIDI input.


I have seen no MacPorts or Homebrew solutions for using rumor.  So I 
was hoping to set up rumor to use with one of the Docker containers 
for LilyDev (preferably the lilypond container, rather than the 
lilydev container).


I have never used Docker before, but I was able to get it set up with 
a few false starts (thanks, Federico!).


Could somebody (maybe Federico) give me some pointers on how I might 
add rumor to a Docker container?  Or maybe set up a new Docker 
container?  Since rumor doesn't add the music into Lilypond files, as 
I understand it, but instead creates music to be pasted into a 
lilypond source file, I think I could use rumor in a Docker 
container, and paste the results of a rumor run into a Frescobaldi 
window.




You should thank Dan Eble for all the work on the Docker container.
I think you can just add the rumor package in the Dockerfile and build 
the image.
