Re: Restricting cross staff stems

[Andrew Bernard]

Hi Malte,

Many thanks to you. Although I had said I did not want to fudge this
scenario by shiftng the notes to make them miss the crossStaff alignment, I
was unaware that the sensitivty of crossStaff is so high, and this small
move not only works just fine to suppress the crossStaff but is completely
unobservable. Not such a bad hack after all. One could even create a
function \crossStaffOff and just use this. Quite acceptable I think.

Sorting out annotation interface questions (GSoC)

[Urs Liska]

Hi all,

our GSoC student Jeffery has done quite some work on writing a
comprehensive LaTeX package to typeset annotations produced from a
LilyPond document. I assume he'll soon wrap it up to merge something
like a V1.0, but we've started turning to work on the LilyPond side of
things already, enhancing the existing state of the ScholarLY package
(https://github.com/openlilylib/scholarly).

Right now we're discussing a few things on the interface for defining
annotations, and I suggested to extend this discussion to the
lilypond-user list.

Right now we have a number of annotation *types*, expressed through the
commands \musicalIssue, \criticalRemark, \lilypondIssue, \question and
\todo. They are used as (e.g.)

\criticalRemark \with {
  author = "Urs Liska"
  context = "Piano, r.h."
  message = "Incredibly sophisticated observation"
  my-arbitrary-prop = "User can use custom properties"
} Slur c ( d )

Annotations (can) *refer* to a type of fact in the sources, for example:
“pitch”, “rhythm”, ”paper”, ”watermark”, ”erasure”.
I think it's natural to express this as an additional property (e.g.)
"category":

\musicalIssue \with {
  author = "Urs Liska"
  context = "lyrics"
  message = "Should ß be changed to ss here?"
  category = lyrics-modernization
} LyricText
Fluß

(Instead of a symbol this can also accept a symbol list for multiple
categories.)
Maybe that's better called "tags"?

Finally annotations can refer to the type of editorial action/decision
it does. At least for musical issues and critical remarks. The
annotation can refer to an editorial addition, deletion or emendation.
Here it is currently not clear whether this would warrant a separate
property or if it can be understood as a kind of subset of the tags
discussed before. But it should be considered in the context of another
issue:

Annotations can trigger (to-be-implemented) "editorial functions" that
apply visible highlighting, for example produce dashing for slurs that
have been added by the editor. This could be expressed by a property
*apply*:

\musicalIssue \with {
  author = "Urs Liska"
  context = "violin 1"
  message = "Slur obviously forgotten in original edition"
  apply = addition
} Slur

My question is: is this "application" the same as the type of annotation
action from the previous issue? Or could it occur that a project wants
to document types of editorial decisions independently from applying
visual indications of that?

Any feedback appreciated
Urs

Unfortunately, it's a little more complicated in 2.18.2, but the
development version has:

4.2.2 Setting the staff size

3. To set the staff size for a single staff within a system,
   use the \magnifyStaff command.
   For example, traditionally engraved chamber music scores
   with piano often used 7mm piano staves while the other
   staves were typically between 3/5 and 5/7 as large (between
   60% and 71%). To achieve the 5/7 proportion, use:
   \score {
  <<
\new Staff \with {
  \magnifyStaff #5/7
} { ... }
\new PianoStaff { ... }
  >>
   }
   If you happen to know which fontSize you wish to use,
   you could use the following form:
   \score {
  <<
\new Staff \with {
  \magnifyStaff #(magstep -3)
} { ... }
\new PianoStaff { ... }
  >>
   }
   To emulate the look of traditional engraving, it is best
   to avoid reducing the thickness of the staff lines.

Cheers,
David.

I've to admit I forgot about grob-transformer, before you mentioned it.

David K put up some examples replying to user requests, but I think it
should be documented more widely, maybe a snippet in
/Documentation/snippets will do it already or additionally(?) an entry
in the extending-manual.

To be fair, it isn't the "same musical moment" at all unless your name
is LilyPond.

Well, I tend to cheat with the "same musical moment" rather than the
graphics.  In this case, I'd likely use something like

\new Score \with { \numericTimeSignature }
\repeat volta 2 { c1 }
\alternative { { \time 3/4 c2. \grace { \bar "" \time 4/4 s128 } }
   { \time 3/4 c2. } }

The spacing is not perfect but not all that bad.

LilyPond interprets the input successively, repeats are disregarded.

So your problem can be reduced to:
{ \time 3/4 R2. \time 4/4 \time 3/4 R2. }
where you want to print two TimeSignatures at the same musical moment.
LilyPond will _never_ do this.
Honestly, I've never seen this before.

Anyway, to get it printed as you like you'll have to work around.
Here I choosed to hack BreathingSign.
Ofcourse it's pure graphical and you have to repeat it in any Staff:


\version "2.19.44"

insertTime =
#(define-music-function (fraction)(fraction?)
#{
  \override BreathingSign.stencil =
#(lambda (grob)
  (ly:grob-set-property! grob 'fraction fraction)
  (ly:grob-set-property! grob 'Y-offset '())
  (ly:grob-set-nested-property! grob
'(space-alist staff-bar) '(extra-space . 1.0))
  (ly:time-signature::print grob))
  \breathe
#})

{ \time 3/4 R2. \insertTime 4/4 \time 3/4 R2. }

Hello,

Try adding the following \with block to your Staff:

\new Staff \with {
  fontSize = #-3
  \override StaffSymbol.staff-space = #(magstep -3)
  \override StaffSymbol.thickness = #(magstep -3)
} {
   % Music follows here
}

it's been a while since I used LilyPond so this knowledge might be a bit 
out of date... I think in the development version there's a new way to 
do this.

Hello Federico,

I meant like inside the 1st alternative ending of the repeat. There is a 
3/4 at the beginning and a 4/4 at the end. Do you see it?


When I try to do this in LilyPond:

\alternative {
  { \time 3/4 f8 f( aes16 bes des8~des) des \time 4/4 }
  { _*\time 3/4*_ f,8 f( aes16 bes des8~des) \mark \markup { 
\musicglyph #"scripts.coda" } }

}

... then I don't see the 4/4 time signature at all, but if I delete the 
marked signature (the second \time 3/4), it does show up, though in the 
wrong place (it appears after the bar instead of before it).


Kind regards,

Here's a minimal example:

There shouldn't be a problem with the larger staff sizes. There are a
number of things you can do like increasing note spacing (see the
"Horizontal Spacing" section in the Notation Reference for specific
examples), putting in manual \break and \pageBreak commands. There's also
using some of the \paper variables to encourage the layout algorithm to
spread the measures out more, like

\paper {
  system-count = 4
  page-count = 2
  % etc.
}

Hi Ryan,

below next try.
I'm not really convinced though, see REMARK

\version "2.19.44"

%% REMARK
%% The code below keeps the default glissando-stencil, while adding some
%% text to it. This means the text-stencil needs to be rotated to match the
%% glissando; also some reasonable padding between them needs to be found.
%% It turned out being a pretty difficult task to do so with reasonable
%% exactness and the current code is not always convincing, although usable.
%%
%% TODO
%% Test whether constructing a glissando+text-stencil from scratch causes better
%% results

A very useful function!

It occurs to me that you could override 'positions directly without
consulting the stencil, instead of as a side-effect:


%% ===
tupletAngles =
#(define-music-function (y-off angl)(number? number?)
   "
 y-off a (possible) offset in Y-direction
 angl is supposed to be the angle of the TupletBracket in degrees,
 "
   #{
 \once\override TupletBracket #'positions =
 #(lambda (grob)
(let* ((pos (ly:tuplet-bracket::calc-positions grob))
   (y-length (interval-length pos))
   (x-length (interval-length
(ly:tuplet-bracket::calc-x-positions grob)))
   (alpha (degrees->radians angl))
   (dir (ly:grob-property grob 'direction))
   (new-start (+ (if (= dir 1)
 (max (car pos)(cdr pos))
 (min (car pos)(cdr pos)))
y-off))
   (new-y (* x-length (tan alpha
  (cons new-start (+ new-start new-y
   #})

horizontalTuplets =
\override TupletBracket  #'positions =
#(lambda (grob)
   (let* ((pos (ly:tuplet-bracket::calc-positions grob))
  (dir (ly:grob-property grob 'direction))
  (new-pos (if (= dir 1)
   (max (car pos)(cdr pos))
   (min (car pos)(cdr pos)
 (cons new-pos new-pos)))

%% ===

(For newer versions, maybe it would be helpful to work in the
grob-transformer function?)

Re: Time signature before end of volta repeat

Hi Imanuel

Welcome to LilyPond.
LilyPond should print the new time signature before and after a line 
break, just like in the example you linked.

Here's a minimal example:

\version "2.19.43"
{
 \time 2/4
 \repeat volta 2 {
   c2 c c c \break
 }
 \alternative {
   { \time 3/4 d2. }
   { e2. }
 }
}

Can you provide a minimal example showing what's the problem?

P.S. This is my first post on a mailing list. :D So please forgive me if 
I make any mistakes.
