There's a sort of definition in Learning Manual 4.3.3: "Distances and 
lengths in LilyPond are generally measured in staff-spaces, the distance 
between adjacent lines in the staff".

Re: Combining Multimeasure rests

[Urs Liska]

No idea anybody?

I think I can narrow down the question even more:

Running the attached file gives


(make-music (quote Music))

on the command line. So what I need seems to be a test that returns true 
if passed the above Scheme construct.

I'm not completely sure if that will bring me forward, but I do hope so ...

I’m not sure what ‘\staff-space’ is. I know the meaning of ‘staff-space’ 
(without the slash), though.  Is that what you meant?

This is possible with a custom Scheme function but not currently part of 
LilyPond.
It is, however, part of abjad if you want to go down that route - 
abjad.mbrsi.org It has a pretty complete LilyPond parser and can do all sorts 
of cool merging stuff.

Well, it *is* from the context of a Scheme function, which is attached 
to the initial post of this thread.

abjad.mbrsi.org  It has a pretty complete 
LilyPond parser and can do all sorts of cool merging stuff.


While I have been interested in looking at abjad for quite some time I 
don't think that's a possible approach here.
I have my input files and they contain function calls in between the 
music or rests. Depending on the compilation context these functions 
return breaks or nothing, so they are just there. And parsing/updating 
the input files is not an option.


The combinable-rest? predicate in the function files considers an 
'element of the ly:music? it is passed combinable if it is

- a rest and
- is called 'MultiMeasureRestMusic and
- doesn't have any 'articulation

What I need is a way to either
- accept the above construct of an empty music function in the 
combinable-rest? test or

- drop the item from the 'elements list

No, I mean `\staff-space', e.g.

  line-width = 50\staff-space

as documented in section `Distances and measurements'.

Note that I can similarly say

  line-width = 10\staff-height

so I suspect it's the code in function `set-paper-dimension-variables'
together with 'layout-set-absolute-staff-size-in-module' (both in file
`paper.scm') that defines the commands and its values.

Interesting - never knew this existed.
It seems suspicious.  What happens is that in paper-defaults-init.ly, there is 
a line:

  %% ugh. hard coded?
  #(layout-set-absolute-staff-size (* 20.0 pt))

The comment says it all :-) Not that I am not guilty of hardcoding…no stones 
are thrown…

Jump to paper.scm, where we have:

layout-set-absolute-staff-size

that calls:

layout-set-absolute-staff-size-in-module

which sets staff-space as the staff height / 4.

So beyond the hard coding of 20.0, there is a further layer of (uncommented) 
hard-coditude that assumes we have 4 spaces in the staff.

Re: Combining Multimeasure rests

Cool, after learning lots about types and stripping elements out of a

For reference:
(make-music (quote Music))

was the question.

#(define test (make-music (quote Music)))

#(display (ly:music-property test 'name))


returns


Music


So my problem could be solved by checking if an argument is ly:music? 
and if its 'name property is "Music".


I'll include that function in openLilyLib soon.

lyrics extender and acciaccatura

[Jean-Charles Malahieude]

Hi all,

Trying to align a syllable to acciaccaturas, I came across an extender 
problem:


The extender should stop *before* the rest, not when encountering the 
next acciaccatura.


\version "2.19.15"

Music = {
  r4 \acciaccatura { c'8 } e'4~ e'2~
  e'1
  r4 \acciaccatura { e'8 } c'2.
}

TextKO = \lyricmode { Ah __ KO }
TextBetter = \lyricmode { "Ah __" Hum }

\score {
  \new Staff <<
\new Voice = "music" { \Music }
\new Lyrics \lyricsto "music" \TextKO
\new Lyrics \lyricsto "music" \TextBetter >>

  \layout { }
}

The problem I see here is that the X-parent of the LyricText is being set

Hi Kieren,

I will have a look at it, and I also have some ideas about options for a 
more manual approach to line breaking (partially from seeing how easy it

But for now I've found the solution for my case (i.e. the merge of rests

Re: Where is \staff-space defined?

[Kieren MacMillan]

Hi Mike (et al.),

While you’re in the spacing world…  ;)

Is there any way that a function could give horizontal setting values (e.g., 
bound-padding) in terms of a rhythmic moment [in the current measure]? e.g.,


\override Hairpin.bound-padding = #’(length-of-moment 1/8)


would give horizontal space equal to the width of an eighth note “right now, in 
this [part of the] measure”.

I imagine computing that would have to come after all other horizontal spacing 
was determined, and the layout set — and thus it might be impossible (or at the 
very least unfeasible) — but I thought I’d ask anyway.

Thanks,
Kieren.

   \new Voice = "music" { \grace c'8 }
   \new Lyrics \lyricsto "music" { hi }




Not much of a surprise here.

\new Staff <<
   \new Voice = "music" { \grace c'8 }
   \new Lyrics \with { includeGraceNotes = ##t } \lyricsto "music" { hi }






Thanks, David. I was sure to have seen something about it. Unfortunately 
dig not enough deeply since this clause is only mentioned in NR2.1.3 
Stanzas (as a @subsubheading in "Stanzas with different rhythms") 
instead as in 2.1.2 with "Placing syllables horizontally"!


Even better, includeGraceNotes takes care of the extender's problem that 
was most annoying.

What's the problem?  `paper-defaults-init.ly' sets up the default
value, 20pt.  Admittedly, the comment is irritating, and I wonder why
it is there...

I’m guessing it’s because all the other values in the vile (mm, in, pt) are
in variables whereas the 20.0 is not in a variable but rather hardcoded
as an argument to the function.

A cm will always be a cm, but the staff space as defined here will change if 
its tabs vs traditional staff notation.
It’s just a bit misleading.

I’m not opposed to having this, but perhaps it’d be worth to change the name to 
\five-line-staff-space?

Repeat Volta Bar Types

[Chris Crossen]

Is it possible to get different repeat bar images when using \repeat volta ?

I am post processing the images produced by LilyPond and would like to use a 
double-bar in place of the begin-repeat and end-repeat bars. After my 
post-processing, I can replace the double-bars with the normal repeat bars to 
keep the piece musically correct.

Thank you,

One way, although probably not the best way, is to simply
specify the bar type with the \bar directive:

\version "2.19.3"
\new Staff {
  c'1
  \bar "||" 
  \repeat volta 2 { c'1 c'1 }
  \bar "||"
}

I don't know how to make this work in all cases, however.  Remove
the first bar, for example, and this method breaks.

And we have context-properties for this:

\version "2.19.3"

\layout {
  \context {
\Score
startRepeatType = #"||"
endRepeatType = #"||"
%% not needed in the minimal example
%doubleRepeatType = #"||"

\new Staff {

Thanks, Harm.  But that still doesn't work in the case where the
volta is at the beginning of the piece, and the engraver wishes
an explicit bar line.

Lily by default doesn't engrave an open volta at the start of a
piece, or at a double-barline.  I don't know how many others do,
but I, for one, often override this.

Both of these cases fail:

\version "2.19.3"

\layout {
  \context {
\Score
startRepeatType = #"||"
endRepeatType = #"||"
%% not needed in the minimal example
%doubleRepeatType = #"||"
  }
}

\score {
  \new Staff {
%c'1
\bar "||"
\repeat volta 2 { c'1 c'1 }
  }
}

\score {
  \new Staff {
%c'1
\bar ".|:"
\repeat volta 2 { c'1 c'1 }
  }
}

(Sorry for the last empty mail, misclicked.)

It's because \bar "||" will not print anything at line-begin.

Though consider the following:

\version "2.19.13"

\new Staff {
  \bar ".|:" \repeat volta 2 { c'1 c'1 }
}

#(define-bar-line "||-r" "||" "||" "||")

\score {
  \new Staff {
\bar "||-r"
\repeat volta 2 { c'1 c'1 }
  }

  \layout {
\context {
  \Score
  startRepeatType = #"||-r"
  endRepeatType = #"||-r"
  %% not needed in the minimal example
  %doubleRepeatType = #"||-r"
}
  }
}

Yes.  And perhaps because \bar ".|:" (intentionally?) does not
respect \Score.startRepeatType?

Lyric Spacing With Slurs - Help Requested

[Br. Cody Jorgensen]

Dear Lilypond Community,


I’m highly unsatisfied with the readability of my melismatic notes in modern 
notation. The spacing seems to be off, with the slur placing the right-most 
note almost as if it were a part of the next lyric’s note. I’ve searched in 
vain (quite some time!) for a way to adjust the horizontal spacing of the slur.


Example (using lilypond 2.18.2)


\score {
 \new Staff \relative c' {
   \time 3/4
   \key g \major
   e4( f) g  | f( d) fis |

 }

}

\addlyrics {
  San -- ctus  |  San -- ctus |

}


Produces the following output:

 


I would like to adjust the horizontal spacing so that the last note of the slur 
is more near the first. It almost appears, without the slur as if the “ctus" is 
the melismatic syllable.


I greatly appreciate any pointers, and apologize for any posting standards I 
have not followed. Your mercy is appreciated!!

The horizontal spacing of the whole phrase will partially determine what the 
score looks like…

Here’s a modified snippet that might give you some hints about things you can 
do to tweak your scores to your liking:

theMusic = {
  \time 3/4
  \key g \major
  e'4( f') g'   |
  f'( d') fis'   |
}

theWords = \lyricmode {
  San -- ctus
  San -- ctus
}

\score {
  <<
\new Staff \new Voice \theMusic
\addlyrics \theWords
  >>
  \layout {
line-width = 4\in
ragged-right = ##f
\context {
  \Score
  \set lyricMelismaAlignment = #-0.7
}
  }
}

Hope this helps!

After investigations I now know that the unit of `SIZE' is indeed
Typographical Points.  This *must* be mentioned right there, since it
otherwise contradicts a statement from section `Distances and
measurements':

  Absolute distances are used for specifying margins, indents, and
  other page layout details, and are by default specified in
  millimeters.

I've applied the corresponding trivial patch to the doc string of
`\abs-fontsize' directly to staging.

Given that responses on this list are often within minutes, and these
my questions stayed unanswered I guess that no-one has thought about
this, which actually surprises me.

Well, below is my solution for such a function.  It took me a very
long time to find out how to compute the factor between the default
global size (20pt) and the actual value set with
`set-global-staff-size'.  Is there a better way?

I suggests that something similar – possibly improved – gets added to
the lilypond core.

Re: absolute font size issues

An alternative to `\abs-baseline-skip' is a scaling function
`pt-to-staff-space', see below.  While being more versatile, it's
probably more awkward to use...

#(define-public (pt-to-staff-space size)
   "Convert from points to staff space units."

   ;; The value `output-scale' gives the size (in mm) of the staff space at
   ;; the global staff size.  By definition, the staff space for a staff
   ;; size of 20pt is 20pt / 4 = 5pt.
   (let* ((5pt (ly:pt 5))
  (output-scale (ly:output-def-lookup $defaultpaper 'output-scale 1))
  (factor (/ output-scale 5pt))
  (staff-space (* 5 factor)))
 (/ size staff-space)))


\header { tagline = ##f }
\paper { print-page-number = ##f }

#(set-global-staff-size 25)

\markup { \abs-fontsize #200 {
\override #'(baseline-skip . 40) {
  \column { A A } } } }

\pageBreak

\markup { \abs-fontsize #200 {
\override #(cons 'baseline-skip (pt-to-staff-space 250)) {
  \column { A A } } } }

Given that responses on this list are often within minutes, and these
my questions stayed unanswered I guess that no-one has thought about
this, which actually surprises me.



Well, I was about to answer, but somehow ...

I defined some \abs-... markup commands myself and wondered if it would 
be feasible to implement a "switch" – something like \absoluteSizeOn
or similar, to avoid the need of defining everything twice –  with 
relative sizes and absolute sizes, respectively.


IIRC, this idea was discussed a long time ago, but the dicussion never 
reached the "critical mass" ;-)
