edit to Lilypond wikipedia article

[David Olson]

Hi Lilyponders, 

I just added a sub-section about lyLuaLaTeX to Wikipedia 

[ https://en.wikipedia.org/wiki/LilyPond#Integration_into_LaTeX | 
https://en.wikipedia.org/wiki/LilyPond#Integration_into_LaTeX ] 

If some of you take a look and make changes 
(or instruct me to do so), it can be better. 

Respectfully,

Re: eartraining with lilypond?

Hello Stefan & all,

well, while NOT being a programmer, nevertheless I created a little
web-based cgi-program especially for training note-reading, and it
contains also a part for training absolute hearing.

It's all related to a piano-graphic, on which You can click the
random-created note You've read btw. heared, and it will give a
feedback, if it was wrong or write.

One can chose different difficulties.

The note-reading part contains also some interval-training parts.

What does it have to do with lilypond?
Well, the note symbols I've used are created by lilypond. :-)

I made it in 2010 (3 month) and 2012 (2 month), and it's missing a
chord-training part, but I won't continue this program, and due to not
being a programmer, the code is nearly unreadable (perhaps meanwhile
also for me).

So You can only use it as is.

The good thing is:
There is no costs, no "Werbung", no cookies and so on, the only thing
you have to create is an own two-part user name and an own passwort at
the first session, for getting a later feedback about your progress in
following sessions.

To get the site, you cannot only type

http://www.roland-goretzki.de

because this website I've closed several years ago. But you can get it
by typing the direct URL:

http://www.roland-goretzki.de/cgi-bin/lernspiel.cgi

There You will be asked a user name, it is:
roland
And You will be asked a password, it is:
benjamin

After this you get directly into the program, where You have to create
your own user name and password as mentioned above. The rest ist mostly
self-declaring, I think.

For potential further questions in detail I would prefer the German
language, because I'm no English native speaker, and I assume, You are a
german, don't You?

For all English speakers:
The program is only in German language, I'm sorry.

Best Regards   Roland

PS:
Don't know why I didn't share it in the past - perhaps simply forgotten
OR due to the language and the necessary declaration? ;-)

Read git tags using Scheme

[Noeck]

Hi,

I am using the function below which is adapted from
http://lilypondblog.org/2014/01/why-use-version-control-for-engraving-scores/#more-2151

While it works and the .ly files compile successfully, the function
issues a warning (?) I’d like to get rid of.

1) If the document is in a git directory, this is printed:

 Parsing...git: /…path/to…/lilypond-2.20.0-1/lilypond/usr/lib/libz.so.1:
 no version information available (required by git)

Where does it come from and why is it issued?
Doing `git --version` in bash does not issue it.

2) If the document is not in a git repository another log line is added:

 fatal: not a git repository (or any of the parent directories): .git

Which I understand but I’d like to hide it anyways because I want to use
the same file no matter if it is used with git or not.

Any ideas how to achieve this?

Cheers,
Joram

For people who understand lilypond's internals, is it possible to

Let me first clarify I have only skimmed this thread, so I cannot 
comment on the alignment issue at hand nor whether a custom engraver 
would help.  Rather, I just wanted to speak to your next question:



Or does it have to be written in c++ since a lot of other

There has been a lot of work to enable creating Scheme engravers, though 
not all functionality in C++ is directly exposed to Scheme.  So while 
you might need to reimplement the logic of some helper functions, I 
would say most of what is done in C++ can be done in Scheme.

RE: Running convert-ly on WIndows

[John Schlomann]

Hi Michael,

Thank you for your response.

It appears to be working now. I added environment variables PYTHONPATH and 
PYTHONHOME. I'm not sure they're both needed. I might try removing PYTHONHOME. 
If either of these are described in the LilyPond doc I complete missed them.

PYTHONPATH contains two paths:
  C:\Program Files (x86)\LilyPond\usr\bin
  C:\Program Files (x86)\LilyPond\usr\lib\Python2.4

PYTHONHOME contains only the first of those paths.

Now on to converting several hundred .ly files, including a lot of Scheme code.

Best regards,
John

RemoveEmptyStaves doesnt remove percussion staff

[neuro黃學仁]

How can one remove the empty percussion staff in Grandscore?
The \RemoveEmptyStaves seems not working on percussion staff.

Sample files can be reached at http://orchestra.tw/lilypond_Q
including:
00.ly
bdrum.ly
timp.ly
v1.ly
v2.ly

To run lilypond 00.ly (http://orchestra.tw/lilypond_Q/00.ly),
and it results in 00.pdf (http://orchestra.tw/lilypond_Q/00.pdf)

Thanks very much for any advise~

This sure sounds like the familiar issue with an OS version of
Ghostscript not matching that expected by LilyPond.

What LilyPond version did you use, the download from lilypond.org?
Did you run LilyPond from the command line or from Frescobaldi? I have
the impression that Frescobaldi for some reason chokes again with this
problem (although I think I had fixed it in the past), but didn't have
the time to properly investigate.

Re: resetting accidentals at word breaks

[Lukas-Fabian Moser]

Hi Benjamin,


accidental-styles.chant-cautionary =
#`(#t
      (Staff ,(make-accidental-rule 'same-octave 0))
      (Staff ,(make-accidental-rule 'same-octave #t)))

Great to hear!

Now I am trying to figure out how to draw the first accidental within 
a melisma at the beginning of the group of notes rather than 
immediately before the note it modifies.  I'd be interested if anyone 
has any ideas where to start on that.  I will consult the 
documentation and see what I can come up with.


This is an interesting feature that should also be needed in some forms 
of traditional Gregorian chant notation. (The Graduale Novum uses


but the chosen place is not simply "beginning of word".)

Maybe this could be done by constructing an engraver that i) keeps track 
of possible accidental-start-positions (i.e. word beginnings in your 
case), ii) watches out for accidentals and moves them back horizontally, 
either a) by graphically X-offsetting them or b) by adding an accidental 
to the first note of the word (with Y-offset).


Unfortunately, this is completely out of my depth, but I wouldn't be 
surprised at all (yet quite impressed) if, for instance, Aaron or Harm 
were able to come up with something like that.


Assuming, of course, that this is not already implemented by the 
Gregorian folks?

I hope you don't find this question insulting, but you didn't by chance 
have the PDF files open in Adobe reader or some other PDF viewer that 
locks the file? If so, the simple solution is to close the PDF file 
before trying to run Lilypond.


If not, it might help others to provide debugging hints if you tell what

Denemo (a graphical front end for LilyPond) has various educational
games. One I added recently works by playing a few notes at random from
a bar of music and the waiting for you to play the last played note on
your MIDI keyboard. The idea is that you create a bar of music with a
selection of notes you want to practice and then run the game on that.
Some of the older games play intervals and ask you to name them, etc.
Not really anything to do with LilyPond though...

Re: Alignment issues of Time signature above the staff

[Chen Leo]

Hi Kevin,

Thank you for your suggestion.

I have looked into the source files of lilypond, and the original 
time-signature-engraver is written in c++.

https://github.com/lilypond/lilypond/blob/master/lily/time-signature-engraver.cc

For people who understand lilypond's internals, is it possible to write a 
custom time-signature-engraver that synchronise with the barlines and does not 
add extra space to other staves by just using scheme? Or does it have to be 
written in c++ since a lot of other files seems to be included in the original 
time-signature-engraver file?

Thanks,
Leo

eartraining with lilypond?

[Stefan Thomas]

Dear community,
has someone experiences and/or ideas for using lilypond for
eartraining-purposes?
I know, there is gnu-solfege, but it has the disadvantage, that it doesn't
exist as an app or can be used browser based.
Are there other projects/ideas around?
Thanks,
Stefan

Thanks.

Well, you just *did* submit a patch, and I'm going it to apply soon.
BTW, you can also send e-mails to the 'bug-lilypond' list without
being subscribed; it just takes longer until such e-mails are
forwarded from the quarantine area, and you might miss responses.

Note that those 'barriers' have mainly historical reasons; we will
probably soon move to a different system that should provide a better
framework for one-time patches like yours.

On the other hand, submitting patches regularly needs *a lot* of
self-discipline, this is, you have to follow strict rules to make a
good-looking patch – you can't expect that developers are cleaning up
random contributions.  Believe me, submitting via git-cl or doing a
pull request on github and friends is just the last step, and it is by
far the easiest part in the whole process.

Care to share more details on what you do exactly?
Exact command, where you invoke it etc. pp.

SVG style and contributing barrier to entry

Hi!

I just discovered that the “style” tag created inside svg output uses
the wrong syntax, e.g.

```
