Re: Line break in beam including rests

[Robert Schmaus]

Hi Nils,

Add 

\override Beam. breakable = ##t

before the break in the second example. That should do it ...

Line break in beam including rests

[Niels]

Dear Lilypond-group,

I want to break after a bar.
In the first example this shown.
However, when a beam spans the break the 8th rest in example 2 causes a 
problem. How can I create a line break here?


Thanks for your help,

Yes, and just for the record: it's not the rest that's changing the

Piano pedal mark collision (\sustainOn, \sustainOff)

[Przemyslaw Pawelczyk]

Hi!

I have a problem with \sustainOn and \sustainOff colliding each other
in some cases.
I use following pattern

s32*31\sustainOn s32\sustainOff

instead of

s1\sustainOff\sustainOn

to achieve a bit better pedalling in MIDI, but it often looks bad on the paper.

Is there any way to improve it globally?
Is there any way to fine tune horizontal position of the pedal indication?

Or maybe there is even a way to use some Scheme magic that would allow
writing simpler form (s1\sustainOff\sustainOn), yet modifying it for
MIDI (changing off placement by given duration, 32 in  the example)?

Exemplary source file and PDF:
http://paste.przemoc.net/lilypond/piano-pedal-mark-collision/

If your actual file is also organized using different \score blocks you
can achieve what you want by moving the layout block *inside* the score
block:

\score {
  \new Staff { \melody }
  \layout {
\context {
  \Score
  \consists \editionEngraver my.Test
}
\context {
  \Staff
  \consists \editionEngraver ##f
}
\context {
  \Voice
  \consists \editionEngraver ##f
}
  }
}

If that's not what you need please give more details on the actual use
case. It may be that we can help you further

This is what I do, all the time.
I’ve never had any problems with it, so I’m assuming it’s the “correct” way.

n.b. You can even have multiple editions *in the same score*, by adding them 
[individually] to the appropriate contexts inside the \score block.

Determining what parameters exist for an item

[Charles O. Lawrence]

Gentlemen,

 

How can I determine what parameters exist for an item?  For example, what
are all the parameters for a TextSpanner?  If my terminology is not correct,
please correct me.

 

If this kind of information is in the documentation, I cannot seem to
uncover it.  If so, Please point me in the right direction.  Is there a way
to programmatically uncover this information?  If so, please provide this
newbie with a code sample to do it.

Re: Edition-engraver: Multiple editions in same file

[Benjamin Strecker]

Thanks, Urs.

That occurred to me after a good night’s sleep.  I think I have *a*
solution now, but I don’t know if it’s the recommended way to do things.

My project contains four scores where the melody is the same but in
different registers.  There are some modifications that I want applied
universally to each score, but the individual scores have their own
requirements from different BreathingSign collisions, slur shapes, etc.

I now have my file organized with a global \layout block:

\layout {
  \context {
\Score
\consists \editionEngraver beams
  }
  \context {
\Staff
\consists \editionEngraver ##f
  }
  \context {
\Voice
\consists \editionEngraver ##f
  }
}

And each of the scores has it's own layout block consisted with an
editionEngraver unique to that score.  Here are the first two, for example:

\score {
  \new Staff {
<< \melody \dynamics \global >>
  }
  \layout {
\context {
  \Staff
  \consists \editionEngraver firstTreble
}
  }
}


\score {
  \new Staff {
<< \transpose e b \melody \dynamics \global >>
  }
  \layout {
\context {
  \Staff
  \consists \editionEngraver highest
}
  }
}

So far this seems to be working, but I don't know if this is considered the
'correct' way to do it.

So have I kept myself on the beaten path or wandered into inadvisable
territory?

Charles,

Here is the way I do it, without programming.  You may find this less
confusing.

1) Look up the object in the Internals Reference, Section 3.1 All layout
objects.  For TextSpanner, you can use this link for version 2.18:

http://www.lilypond.org/doc/v2.18/Documentation/internals/textspanner


2)  The standard settings on this page tell you the default settings for
this object.  These are the most commonly used, but they are not all.

3) At the bottom of the page, the interfaces the object supports are
listed.  In the case of the TextSpanner,
these are font-interface, grog-interface, line-interface,
line-spanner-interface, side-position-interface, and spanner-interface.
Each of these interfaces has a list of properties found in the Internals
Reference section 3.2.  And the property lists are linked from the
TextSpanner page.

4) Going to one of these interfaces, e.g. the font-interface found in the
Internals Reference, section 3.2.36,

http://www.lilypond.org/doc/v2.18/Documentation/internals/font_002dinterfac
e


provides a list of user-settable properties for that interface, which will
affect any output item having that interface.

All of this is explained in section 5.2 of the Notation Reference.
Please read it for more information.

Carl Sorensen

Actually, you can use pretty-print directly, as of 2.19.18.  See

Yes, but unless I’m missing something, you can’t find the default value(s) 
there, right?

I personally would love to be able to get, for any grob, a list of every

Hello Thomas,

I thought I was replying to the list, but I see now that I sent you a
personal email.  I was inside the archives and clicked on the reply button.
Sorry.  I'm not exactly sure how to respond and keep the post's hierarchy
going.  I hope I got it right this time.  All I did was reply to the digest
email, strip out what I didn't need, and replace the default subject.

Thanks for the info.  I had not looked at the "Extending"  manual yet.  I
had gone through first two chapters of the "Learning" manual already.  I had
already "googled" and downloaded a Scheme and Guile manual.  I also had
discovered the "Scores of Beauty" blog, but had not gone through all the
Scheme tutorials yet.  I have a lot of reading studying to do.  Your reply
has been very helpful.

Thanks,

LilyPond uses an input language, which you will need to learn. Best start
reading the "Learning Manual".
Scheme/guile is used as an extension-language in LilyPond. A good starting
point for getting deeper into it is the "Extending Manual".
And ofcourse the guile-manual itself, please note we use guile-1.8 Apart
from the guile-manual, there are a lot of tutorials out there.

Details:
display, string-upcase and lambda are native guile
-> see guile-manual
Maybe look at this one, too:
http://lilypondblog.org/category/using-lilypond/advanced/scheme-tutorials/

display-scheme-music is defined in our source and is the scheme-version of
(LilyPond-syntax) `displayMusic', which is explained in the docs.
I sort of abuse it quite often, because it internally uses `pretty-print'.
(In .ly file I would always need to include the relevant module from guile
for pretty-print, which is tedious).
pretty-print puts out nicely formatted lists.
guile and LilyPond provide a plethora of different displaying procedures ...

ly:grob-properties and ly:grob-basic-properties are defined in C++ for use
in guile.
--> see Internals Reference
Same for 'after-line-breaking, which is a dummy-property called at a certain
point during compilation. Nice to put in all sort of stuff or for displaying
this and that, as done here.

`all-grob-descriptions' is an alist defined in define-grobs.scm.
Although it's public you'll find no documentation about it. Reason:
you shouldn't mess around with internals unless you really know what you're
doing ;)

So far the details for the little coding, but I'm afraid my explanations
will more obfuscate then enlightning...

My recommendation would be:
- try to read and understand the codings provided here on the list.
- Read the manuals: LilyPond, guile, guile-tutorials, etc

I'm not a programmer, though as a LilyPond-starter I had found that not all
was as I wanted it to be. So I started to learn guile to say her what to do
how. I did a lot of exercises: defining substitution-functions and
markup-commands, etc And ofcourse it's very good practise to read/understand
code from others and/or try helping other user.
The LSR is quite nice as well
http://lsr.di.unimi.it/LSR/


Hope it helps a bit,
  Harm

Apart from the guile-manual, there are a lot of tutorials out there.

Details:
display, string-upcase and lambda are native guile
-> see guile-manual
Maybe look at this one, too:
http://lilypondblog.org/category/using-lilypond/advanced/scheme-tutorials/

display-scheme-music is defined in our source and is the
scheme-version of (LilyPond-syntax) `displayMusic', which is explained
in the docs.
I sort of abuse it quite often, because it internally uses
`pretty-print'. (In .ly file I would always need to include the
relevant module from guile for pretty-print, which is tedious).
pretty-print puts out nicely formatted lists.
guile and LilyPond provide a plethora of different displaying procedures ...

ly:grob-properties and ly:grob-basic-properties are defined in C++ for
use in guile.
--> see Internals Reference
Same for 'after-line-breaking, which is a dummy-property called at a
certain point during compilation. Nice to put in all sort of stuff or
for displaying this and that, as done here.

`all-grob-descriptions' is an alist defined in define-grobs.scm.
Although it's public you'll find no documentation about it. Reason:
you shouldn't mess around with internals unless you really know what
you're doing ;)

So far the details for the little coding, but I'm afraid my
explanations will more obfuscate then enlightning...

My recommendation would be:
- try to read and understand the codings provided here on the list.
- Read the manuals: LilyPond, guile, guile-tutorials, etc

I'm not a programmer, though as a LilyPond-starter I had found that
not all was as I wanted it to be. So I started to learn guile to say
her what to do how. I did a lot of exercises: defining
substitution-functions and markup-commands, etc
And ofcourse it's very good practise to read/understand code from
others and/or try helping other user.
The LSR is quite nice as well

Hope it helps a bit,
