Hi David,

the problem:
in 2.18. the grob-parent of LyricText was NoteHead for both Voice and NullVoice.

In 2.19.37 it's NoteColumn in Voice and PaperColumn in NullVoice.
More, 2.19.37 returns for the LSR-code:
programming error: cyclic dependency: calculation-in-progress
encountered for #'X-extent (PaperColumn)
(with a buid from master with --enable-checking)

Right now I'm not sure how to deal with it (and when I'll have the
time to take a deeper look)


So far, cheers,

No.  Neither does it do all the smart argument detection and default
arguments that music/event/scheme functions do.

Markups are a pretty messy area of their own.

(face-palm) Ah ha! I knew it was something obvious. Thank you, Harm.

By the way, did the syntax for define-markup-command get simplified like
define-music-function so the "layout props" args aren't necessary anymore?
Just curious.

Using \score in define-markup-command

2016-02-29 Thread Abraham Lee 
All,

I'm trying to utilize the \score markup command within a custom
define-markup-command that accepts a music expression, but I can't figure
out how. I'm probably missing something obvious, but here's a minimal
example:



\version "2.19.36"

\markup {
  I know I can do this:
  \score {
\relative c'' { c8[ c] }
  }
}

#(define-markup-command (ezscore layout props mus) (ly:music?)
  (interpret-markup layout props
#{
  \markup {
\score {
  \relative c'' { #mus }
}
  }
#}))

\markup { But I'd like to do this: \ezscore { c8[ c] } }



Any suggestions?

LaissezVibrerTies, RepeatTies and ties at repeat alternatives

2016-02-29 Thread Malte Meyn 

Hi list,

I’m not very happy about LilyPond’s ties and semi-ties. Some 
problems/questions:


1. Is there any difference between LaissezVibrerTies and RepeatTies 
except of the default head-direction? Or could one save redundant code 
(including different grob names for basically the same thing etc.) here?


2. IMO LaissezVibrerTies are almost always too short. And there are only 
very ugly hacks like http://lsr.di.unimi.it/LSR/Item?id=715 to change 
the length; it would be nice to have a grob property 'length or 
'minimum-length.


3. This is what annoys me most: Hacks like 
http://lsr.di.unimi.it/LSR/Item?id=794 shouldn’t be necessary; instead, 
LilyPond should be able to take input ~ at repeat alternatives and get 
things right automagically. Or at least there should be easy-to-use 
commands for ties from/to barlines so abusing \laissezVibrer and 
\repeatTie isn’t necessary. Probably they should behave as if there was 
a line break and then print only the needed half.


(4. Slurs at repeats aren’t really nice either …)

Some opinions on that? How easy would that be implemented?

Here some ideas for 3. and 4.



\version "2.19.36"

% (approximately) desired output
\relative {
  \tieDown \slurUp % for better readability
  d'2( c~
  \repeat volta 2 { c4 d) c( d~ }
  \alternative {
{ d c) d( \afterGrace c\laissezVibrer { \once \hideNotes d) } }
{ \grace { \once \hideNotes c^( } d2\repeatTie c) }
  }
}

% suggested input
%{
\relative {
  \tieDown \slurUp % for better readability
  d'2( c~
  \repeat volta 2 { c4 d) c( d~ }
  \alternative {
{ d c) d( c~ \stopTieAtBarline \stopSlurAtBarline }
{ \startTieAtBarline \startSlurAtBarline d2 c) }
  }
}
%}

% alternative input: detect needed spanners automatically
%{
\relative {
  \tieDown \slurUp % for better readability
  d'2( c~
  \repeat volta 2 { c4 d) c( d~ }
  \alternative {
{ d c) d( c~ \stopSpannersAtBarline }
{ \startSpannersAtBarline d2 c) }
  }
}
%}

Re: Graphic background behind systems

Hi Paul, 

one more try: I've installed LP 2.19.37.
Yes, it has a different behavior: default whiteout style is the "classic"
old box style that covers everything behind. You can set the "outline"
style:

% ---

\version "2.19.36"
samplePath =
#'((moveto 0 0)
   (rcurveto 0 1 1 1 1 0)
   (rlineto 0 -5)
   (rcurveto 0 -1 -1 -1 -1 0)
   (closepath))

\markup {
  \with-dimensions #'(0 . 0) #'(0 . 0)
  \translate #'(0 . -2)
  \line {
\hspace #33
\with-color #red \override #'(filled . #t) \path #0.1 #samplePath
\hspace #18.2
\with-color #red \override #'(filled . #t) \path #0.1 #samplePath
\hspace #18.2
\with-color #red \override #'(filled . #t) \path #0.1 #samplePath
  }
}

\markup {
  \override #'(style . outline)   % new!!!
  \override #'(thickness . 1)% or whatever you like
  \whiteout
  \score {
\new StaffGroup
\new Staff \with {
  \omit Staff.TimeSignature
}
\relative c {
  \set Score.proportionalNotationDuration = #(ly:make-moment 1/8)
  \override Score.SpacingSpanner.strict-note-spacing = ##t
  c'1 | c | c | c |
}
\layout { }
  }
}

% --- 

Does that work for you?

Cheers, 
Klaus

Hi Paul, 

you could add
  \with-dimensions #'(0 . 0) #'(0 . 0)
which tells LP to behave as if the following markup had the given dimensions
(in this case: no space at all).
Try:

% ---
\version "2.19.25"
\include "include/defs.ily"

\markup {
  \score {
\new StaffGroup
\new Staff \with {
  \omit Staff.TimeSignature
}
\relative c {
  \set Score.proportionalNotationDuration = #(ly:make-moment 1/8)
  \override Score.SpacingSpanner.strict-note-spacing = ##t
  c,1 c
  c
  -\tweak #'extra-offset #'(-2.5 . -15)  % move to right position
  -\tweak #'layer #-1  % place in bottom layer
  ^\markup {
\with-dimensions #'(0 . 0) #'(0 . 0)
\with-color #(rgb-color 1 0.5 0.5) % specify color
\filled-box #'(0 . 1) #'(0 . 25) #1  % specify size
  }
  c
}
\layout { }
  }
}
% ---

Is that what you need?

Abjad bootcamp this July at Stanford's CCRMA

2016-02-29 Thread Trevor Bača 
Hi everyone,

I'd like to take a moment to mention that I'll be teaching a five-day
bootcamp on composing with Abjad this July at Stanford's CCRMA in Palo
Alto, California:

CCRMA: Formalized Score Control: Using Python & Abjad in Music Composition


Friends and very close collaborators Josiah Wolf Oberholtzer and Jeffrey
Treviño will be teaching with me.

Abjad is Python-based composition environment that uses LilyPond for all
stages of notational output, from precomposition all the way through to
publication-quality finished scores. Abjad is especially useful for
composers who think of the music they write in a "formalized" way: that is,
for composers who write with patterns or processes in their music that can
benefit from being object-modeled.

You can read more about Abjad here:

www.projectabjad.org

And you can take a look at finished scores and listen to pieces here:

http://www.projectabjad.org/gallery.html

If you like academic papers, you can read an overview of Abjad here:

https://github.com/Abjad/tenor2015/blob/master/abjad.pdf

We especially encourage intermediate and advanced users of LilyPond to
consider attending the bootcamp: Abjad brings the full power of the Python
programming language to the syntax of LilyPond files that you are already
familiar with. If you've been thinking about adding a programming component
to your compositional process, the bootcamp in July will be an ideal way to
get started.

We're also happy to announce that Stanford has agreed to work with us to
provide a number of scholarships for women composers who'd like to attend
the bootcamp. We think it's important that composers of all backgrounds
from all over the world should have access to technologies to help make
their work as composers more powerful and more fun!

Best wishes for happy composing and engraving to everyone,

Trevor.

Gregor,

How about this:

%

\version "2.19.36"

#(define (qBarNote grob)
  (grob-interpret-markup grob
#{
  \markup {
\concat {
  \hspace #-0.06
  \path #0.12
#'((moveto 0 -0.6)
   (lineto 0 0.6))
  \musicglyph #"noteheads.s2"
  \hspace #-0.02
  \path #0.12
#'((moveto 0 -0.6)
   (lineto 0 0.6))
}
  }
#}))

qBarNotesOn = {
  \omit Stem
  \override NoteHead.stencil = #qBarNote
}

qBarNotesOff = {
  \undo \omit Stem
  \revert NoteHead.stencil
}

\relative c' {
  2 \qBarNotesOn q4 \qBarNotesOff q |
}

%

There's certainly more that could be done to make the functionality more
robust (like checking for duration, style, etc.), but this should at least
get you going.

Thanks Simon
I should have figured that out. What I have figured out is that a post event
may handle a layer change to -1, but leaves the layout as if the graphic
still occupied space above the staff. SO there is extra white space at the
top. I've moved back to 2.18.2 on one machine but cannot ask Lilypond to do
what it doesn't want to do.It is for a graphic design which I can resolve in
svg after output, so I'm not completely stuck. LP is still admirable!!

\version "2.18.2"
\include "include/defs.ily"

\markup {
\score {
\new StaffGroup
\new Staff \with { 
\omit Staff.TimeSignature
} 
\relative c {
\set Score.proportionalNotationDuration = 
#(ly:make-moment 1/8)
\override Score.SpacingSpanner.strict-note-spacing = ##t
c,1 c
c
 -\tweak #'extra-offset #'(-2.5 . -15)  % move to right 
position
 -\tweak #'layer #-1  % place in bottom layer
 ^\markup {
 \with-color #(rgb-color 1 0.5 0.5) % specify color
 \filled-box #'(0 . 1) #'(0 . 25) #1  % specify size
 }
c 
}
\layout { }
}
}

Do you know the difference between

in the above script? It doesn't work without them!


A direction modifier (- for ‘neutral’, ^ for ‘up’ or _ for ‘down’) is 
needed to mark a post event, i.e. in this case a text script attached to 
a note.

Hi Klaus,

I don't really want to go back to an earlier version, so I've been browsing
the LSR and found something which might work in a similar way, though
different to my original plan.

\version "2.11.56"
\relative c'' {
 a1 a  a
 -\tweak #'extra-offset #'(-2.5 . -15)  % move to right position
 -\tweak #'layer #-1  % place in bottom layer
 ^\markup {
 \with-color #(rgb-color 1 0.5 0.5) % specify color
 \filled-box #'(0 . 1) #'(0 . 25) #0  % specify size
 }
 a
}
from 

http://lists.gnu.org/archive/html/lilypond-user/2008-09/msg00083.html

I should be able to move forward with this, though I can't find an
explanation of the tweak prefixes.
Do you know the difference between
-\tweak
^\tweak and 
 \tweak 

in the above script? It doesn't work without them!
Cheers
Paul
