Thank you Phil

I now managed this with

\override MultiMeasureRest.staff-position = #0 from the Documentation
for one voice. The other voice gets s1.

Bernhard

An alternative would be to use the merge-rests-engraver. That way you can 
type rests per voice as they are, and the engraver merges them if they 
happen to be the same length. Very neat.

fwiw, I use the

#(set-default-paper-size "a4" 'landscape)

syntax and everything works just fine and normal for me. I use okular as
my pdf viewer. It seems to be a hard thing to get right, however,
because that cropped print you mention, I seem to get quite a lot with
firefox. If the damn web-page won't print properly losing stuff to the
right, I often select landscape, only to discover the paper prints
landscape fine, but the print itself is still cropped to portrait width!!!

Re: Extend Whiteout property

[Lukas-Fabian Moser]

What you can do now is

  * fork this repository
  * register the fork and the main Github repository as "remotes" in
your local repository (I suggest to name them "github" and
"" if you have the Savannah
repository as "origin")
  * create a branch for your path
  * commit
  * push to your fork
  * create a Pull Request on Github
  * tell us here about it because we won't be automatically notified
about it.

That way anyone can look at your code, and you should be able to 
refine the code together with others.
At some point you may then do the required registrations and upload 
your patch for review (as per LilyPond's Contributrs' Guide), or you 
may ask someone else to "sheperd" your patch through the review process.


Thanks much for the step-by-step description! I think I managed to 
follow it through, now. (I admit I was a bit shocked by my own courage 
after reading the line "lfm83  wants to merge 
1 commit into lilypond:master from lfm83:snapshot/whiteout-nonquadratic" 
- but if I understand it correctly, a) this is what indeed should appear 
and b) the github repository is not the 'real' repository and I couldn't 
do too much harm there anyway?)


But apologies in advance in case I messed up; this whole 
distributed-development business is still a bit of a mystery to me. :-)

PS. Kieren, by now it works for box and rounded-box style whiteouts.

Re: [Frescobaldi] convert-ly don't work in 3.0.1 in Windows

[Federico Bruni]

Hi Anders

I confirm the problem on Windows 7.
Detailed versions:

Frescobaldi: 3.0.1
Python: 3.5.2
python-ly: 0.9.4
Qt: 5.8.0
PyQt: 5.8.1
sip: 4.19.1
poppler: 0.52.0
python-poppler-qt: 0.24.2
OS: Windows-7-6.1.7601-SP1

I wonder if any Windows user using Frescobaldi 3 can confirm it. That's 
why I've added lilypond-user in Cc.


My **guess** is that Frescobaldi is trying to use the bundled python3 
to run convert-ly (which is a LilyPond file) and this is going to fail. 
It does even on Linux:


$ python3 /usr/bin/convert-ly /home/fede/tmp/lilypond/converting.ly

   ^
SyntaxError: Missing parentheses in call to 'print'. Did you mean 
print(log[0])?


The best fix would be make LilyPond convert-ly work on python3 as 
well...
Even though Frescobaldi should handle better this kind of errors and at

I don't see why, unless your PDF viewer is unable to rotate pages.

I avoid ever writing that because it gives the impression that it's
going to produce a4landscape paper output, which of course it doesn't.
NR §4.1.2 has an odd way of saying this: "When the paper size ends
with an explicit ‘landscape’ or ‘portrait’, the presence of a
'landscape symbol only affects print orientation, not the paper
dimensions used for layout." AIUI the effect of the 'landscape symbol
is unchanged: the pages¹ are rotated and the layout changes to match.

> Can’t test printing right now.

OK, but the results of such a test would not in general be applicable
to others, as we all have different printers, queues, drivers, OSes, etc.
Rotating the print on a fixed-orientation page can be an efficient
strategy depending on the individual's circumstances.

Yes, copiers and printers aren't in the habit of saying, "Are you sure?"

¹ I would have written "print" rather than "pages". In the context,
"Pages" invites confusion with the paper itself.

Thanks, especially to Kieren and foxfanfare, for pointing me in the right
direction. I ended up using
score-markup-spacing
markup-system-spacing
markup-markup-spacing

system-system-spacing

OK, I have put my hands on the code that calls convert-ly 
(https://github.com/wbsoft/frescobaldi/commit/ab9cda16d96564a86fd2580c05d3ec86c63b7e51) 
.


It turns out that indeed Frescobaldi just invokes 'convert-ly' (with the 
absolute path, according to the current LilyPond version) without any 
notion of Python2/Python3.


On Linux this is a shell script that explicitly starts the Python 
bundled with LilyPond,


I don't know what exactly happens with this on Windows, but I think it 
*should* work, since it relies on what is bundled with LilyPond, not the 
Python3 from Frescobaldi.


I think I'd need more information to give a better opinion.

Hello,

I just updated from version 2 to the latest version 3 for Windows
(Frescobaldi.Setup.3.0.0-2.exe)
When I try to use convert-ly nothing happens!

The dialog shows up as usual, with the current version and the new
version, but that's it!

If I run convert.ly in the Lilypond bin directory then it works...



What's wrong?

Re: Extend Whiteout property

Hi Lukas-Fabian,

What you can do now is

  * fork this repository
  * register the fork and the main Github repository as "remotes" in
your local repository (I suggest to name them "github" and
"" if you have the Savannah
repository as "origin")
  * create a branch for your path
  * commit
  * push to your fork
  * create a Pull Request on Github
  * tell us here about it because we won't be automatically notified
about it.

That way anyone can look at your code, and you should be able to 
refine the code together with others.
At some point you may then do the required registrations and upload 
your patch for review (as per LilyPond's Contributrs' Guide), or you 
may ask someone else to "sheperd" your patch through the review process.


Thanks much for the step-by-step description! 


You're welcome. I wasn't in the situation to do an actual description at 
the time, but you seem to have managed going through the outline 
yourself :-)


I think I managed to follow it through, now. (I admit I was a bit 
shocked by my own courage after reading the line "lfm83 
 wants to merge 1 commit into 
lilypond:master from lfm83:snapshot/whiteout-nonquadratic" - but if I 
understand it correctly, a) this is what indeed should appear


Yes, that's the point of "pull requests" (or "merge requests" as they 
are named in some other systems).


and b) the github repository is not the 'real' repository and I 
couldn't do too much harm there anyway?)


That's correct too, actually there are even two layers in play here: as 
you noticed it's not the real repository but "only" a mirror, *and* you 
don't have any privileges even on that mirror. You have created a 
"fork", which is yet another mirror, but on Github itself. In that 
mirror you can do what you want, but merging anything into the 
"lilypond" repository would only be possible for someone with "push 
access" to that repository.




But apologies in advance in case I messed up; this whole 
distributed-development business is still a bit of a mystery to me. :-)


AFAICS you didn't mess up, the pull request looks like a pull request 
should look like (I'm not speaking about the code itself, I have no idea 
about that).


So it would be nice if someone with the C++ knowledge could have a look 
at https://github.com/lilypond/lilypond/pull/3 and comment on it there.
Note: the goal is not to merge the branch into the Github mirror but 
only to provide review. Once there is agreement on the code someone 
should sheperd the patch through the regular review process.

PS. Kieren, by now it works for box and rounded-box style whiteouts.

Hi Urs,

thanks for all the detailed explanations!

I just might add that, I think, the C++ part of the changes is almost 
"trivial" (one had to make sure that the stencil-whiteout gets activated 
not only for boolean- or number-valued 'whiteout' property, but for 
pairs [of numbers] as well). The real work is all scheme, namely in 
scm/stencil.scm.
