MetronomeMark in line with sectionLabel

[Edizioni Migliori]

Is it possible to make a MetronomeMark (tempo indication) appear
immediately to the right of a \sectionLabel, ideally also
vertically-aligned? The only way I have found so far is by overriding
X-offset, which seems convoluted. See example below:

\version "2.23.80"
\language "english"
{ \sectionLabel \markup \bold \smallCaps "Gigue"
%\override Score.MetronomeMark.X-offset = #9
\tempo 4 = 100
\repeat unfold 8 c'' }

This sounds like a problem with your setup. What is your OS? How did you 
install LilyPond?


Can you try LilyPond 2.23.80 (the current development version)? It is 
normally more robust with relocations and such.

Re: Omitting the destination on a call to format is deprecated. Pass #f as the destination, before the format string.

[Jean Abou Samra]

Hi Valentin,

Le 29/10/2022 à 00:42, Valentin Petzel a écrit :

Lilypond with Guile 1.8 used a less capable version of the format command that
did not feature a destination argument (the default simple-format of Guile).
With Guile 2  Lilypond uses the full, powerful ice9 format (as can be seen
using #(display format)).

ice9 format takes a destination argument as first argument. This one can be any
output port, #t for the current output port (i.e. you print the result) or #f
to return the result.



Not sure what makes you think that?

Test input:

\version "2.22.2"

#(ly:message "~s ~s ~s"
 format
 simple-format
 (@ (ice-9 format) format))


2.22 output:

# # 
#



2.23.80 output:


#format-string . args) | (deprecated-format-string-only)> #simple-format (_ _ . _)> #ice-9/format.scm:1609:9 (destination format-string . args) | 
(deprecated-format-string-only)>




As you can see, the format procedure loaded by default in LilyPond

files is always the one from (ice-9 format).



As far as I can see, simple-format has always required a boolean or port

as first argument. As for (@ (ice-9 format) format), its first boolean

or port argument is optional in Guile 1, optional with a deprecation

warning in Guile 2, and required in Guile 3.

Problems with pdf output using Lilypond Version 2.20.0

[Ian West]

Dear Colleagues,
I have greatly enjoyed using Lilypond on Apple laptops for many years; 
first Lilypond 2.12.3 on a 2008 Apple Mac., then Lilypond 2.18.2. on Apple Mac 
2008 and Apple MacPro 2012. Finally I bought AppleMacPro M2,2022 running 
Monterey 12.4.
I understood that the 64-bit M2 chip required a later version of 
Lilypond and on 12 August 2022 I downloaded Lilypond Version 2.20.0 (Build from 
11-03-2020 16:32). After a few initial problems (I think having to change the 
default ' or " marks.) I used it successfully, following a manual 2.22.2.
I was urged to use Frescobaldi to enter the text, and I got as far as 
downloading MacPorts-2.7.2-12-Monterey. But [a] I like entering text with the 
straightforward text editor as I have been doing for 10 years, and [b] I do not 
want to bother with MacPorts, Frescobaldi, Ghostscript or any command line 
entry. I do not think I have any use for Lilypond if I cannot go on as before; 
at 80 I am too old to change. 
Fortunately, I have, back at home the old white 2008 Apple MacBook 
running Lilypond 2.12.3. But I am in Mexico for 3 months with the AppleMacPro 
M2,2022. I wish I could edit my library of tunes, but it now jams at the end of 
compiling and there is no pdf, but a rotating wheel; and, occasionally the 
'log' message:

I suspect it is a late stage and trivial problem of writing the pdf. Perhaps 
installing Adobe (or another pdf writer) would cure this. Has anyone any ideas.

Re: Omitting the destination on a call to format is deprecated. Pass #f as the destination, before the format string.

Now these messages you get should either come from
A) The score itself using format
B) The score using a function that uses format

I’ve grepped through the current git master sources and all 
occurances of
format do specify a port. This means that most likely you are using 
some
custom scheme functions or libraries that use format. To fix these 
warnings
replace all occurrances of (format string ...) by (format #f string

such files.

LilyPond uses stems on all notes, although on some notes they
are invisible. In this case, LilyPond tries (but fails) to
use those invisible stems to place the tremolo beam properly.

Actually, even rests (but not multi-measure rests) internally
have stems.

Hi Everybody!

Below is code I pulled from a larger score to show output warnings for 
a tremolo. I have never had much success with the tremolo interface 
because I am a lazy composer who spent 2 months writing the score, and 
typesetting to make it all pretty for the performers is just too much, 
lol. So, I hand them a score with tremolos that don't slant or angle 
properly. I'm sure someone on this list will tell me how to be more 
precise with tremolos in lilypond :).






Unfortunately, tremolos are an area of LilyPond that is known
not to be very polished — in particular, tremolos on whole notes
look ugly, as you found out. You didn't do anything wrong, LilyPond
is just not capable of typesetting this well automatically right
now. See

https://gitlab.com/lilypond/lilypond/-/issues/1444

Meanwhile, you can place them manually by replacing something
like

\version "2.23.80"

\repeat tremolo 8 {
  bes'16 bes''
}


with

\version "2.23.80"

\repeat tremolo 8 {
  \stemDown
  \override Beam.positions = #'(-2 . 0)
  bes'16 bes''
  \stemNeutral
}

Hi Paul,

please always give the link to the LSR snippet:
https://lsr.di.unimi.it/LSR/Item?id=374
and some example code of your use case.

That said...

I'd always use `grob-transformer', if the original value of a grob is
taken and modified (here Stem.stencil with (ly:stem::print grob)).
This procedure was not available back when the snippet was coded, though.
Making for:

\version "2.23.14"

speakOff = \revert Stem.stencil

speakOnI =
  \override Stem.stencil =
#(grob-transformer 'stencil
  (lambda (grob orig)
 (let* ((x-parent (ly:grob-parent grob X))
(is-rest? (ly:grob-object x-parent 'rest #f)))
   (if is-rest?
   orig
   (ly:stencil-combine-at-edge
orig
Y
(- (ly:grob-property grob 'direction))
(grob-interpret-markup
  grob
  (markup #:center-align #:fontsize -2
  #:musicglyph "noteheads.s2cross"))
-2.3)

\score {
  \new Staff {
\relative c'' {
  a8 b a c
  \speakOnI
  g f r g
  b r d e
  \speakOff
  c a g f
}
  }
}

This does not solve your question, but we can start from it.

(1) Most common would be to code a music-function.
I think it's explained in the Extending Manual.
Making for:

speakOff = \revert Stem.stencil

speakOnII =
#(define-music-function (y-pad)(number?)
#{
  \override Stem.stencil =
#(grob-transformer 'stencil
  (lambda (grob orig)
 (let* ((x-parent (ly:grob-parent grob X))
(is-rest? (ly:grob-object x-parent 'rest #f))) ;; no
need to chaeck for  ly:grob?
   (if is-rest?
   orig
   (ly:stencil-combine-at-edge
orig
Y
(- (ly:grob-property grob 'direction))
(grob-interpret-markup
  grob
  (markup #:center-align #:fontsize -2
  #:musicglyph "noteheads.s2cross"))
y-pad)
#})

\score {
  \new Staff {
\relative c'' {
  a8 b a c
  \speakOnII #-2.3
  g f r g
  b r d e
  \speakOff
  c a g f
}
  }
}

(2) Read a custom details,sub-property:

speakOff = \revert Stem.stencil

speakOnIII =
  \override Stem.stencil =
#(grob-transformer 'stencil
  (lambda (grob orig)
 (let* ((x-parent (ly:grob-parent grob X))
(is-rest? (ly:grob-object x-parent 'rest #f)))
   (if is-rest?
   orig
   (let* ((details (ly:grob-property grob 'details))
  (my-y-move (assoc-get 'my-y-move details -2.3)))
 (ly:stencil-combine-at-edge

This works fine, writing "\speak c4" for instance.

However, I'd like to be able to parameterise the position of the cross 
which is hard-coded as -2.3, so that I can write "\speak #-3.8 c" for 
instance.  I've tried a couple of ways to write it, but I can't find 
one that works.  I suppose that I will need something like "lambda 
(grob posn)" to define the parameter for use at the end, but I can't 
see how to get the value of posn from the LilyPond source into the 
Scheme procedure.


Review the documentation on defining and using music functions:

[1]: 
https://lilypond.org/doc/v2.23/Documentation/extending/music-functions


You could end up with something like this:


speak =
#(define-music-function
  (position)
  (number?)

  (define (stencil-proc grob)
   (let* ((x-parent (ly:grob-parent grob X))
  (is-rest? (ly:grob? (ly:grob-object x-parent 'rest
(if is-rest?
 empty-stencil
 (ly:stencil-combine-at-edge
  (ly:stem::print grob)
  Y
  (- (ly:grob-property grob 'direction))
  (grob-interpret-markup grob
   (markup #:center-align #:fontsize -2
   #:musicglyph "noteheads.s2cross"))
  (- position)

  #{ \once \override Stem.stencil = #stencil-proc #})

{
  \speak 1.6 g'4
  \speak 2.2 b'8 8
  \speak 2.8 a'2

Tremolo

[Craig Bakalian]

Hi Everybody!

Below is code I pulled from a larger score to show output warnings for a 
tremolo. I have never had much success with the tremolo interface 
because I am a lazy composer who spent 2 months writing the score, and 
typesetting to make it all pretty for the performers is just too much, 
lol. So, I hand them a score with tremolos that don't slant or angle 
properly. I'm sure someone on this list will tell me how to be more 
precise with tremolos in lilypond :).


here is the code snippet:

\version "2.23.14" \score {   \new Staff   {     \time 4/2     \key bes 
\major     \repeat tremolo 8 { aes'16 aes''} \repeat tremolo 8 { bes'16 
bes''} |     \repeat tremolo 8 { bes'16 bes''} es''16[ d'' a' bes'] 
bes''[ a'' d'' es''] es'''[ d''' a'' bes''] a'''4 \fermata  |   } }


The warnings:

Re: Passing a parameter to Scheme

[Paul Hodges]

On further thought, I suspect that I can't aim at "\speak #-3.8 c" because 
#-3.8 isn't a music expression so LilyPond won't let me.  I guess I'll need to 
use a \tweak or \set on the parameter variable instead.  But that leaves me 
even further from knowing how to write it, largely because my brain's model of 
computing (honed over 55 years) is entirely based on procedural languages with 
nested scopes (Algol, C) or Assembly language with everything global.  I simply 
don't know how scopes and namespaces work in Scheme, and thus how to define 
that parameter in a way that I can access it to tweak.

 Subject:   Passing a parameter to Scheme 

I am trying to make my first steps in actually modifying some Scheme.  I am 
using a procedure taken from the snippets repository to add a cross to a stem 
(e.g. to indicate sprechgesang):


%%

speak = {
  \once \override Stem.stencil =
    #(lambda (grob)
       (let* ((x-parent (ly:grob-parent grob X))
              (is-rest? (ly:grob? (ly:grob-object x-parent 'rest
         (if is-rest?
             empty-stencil
             (ly:stencil-combine-at-edge
              (ly:stem::print grob)
              Y
              (- (ly:grob-property grob 'direction))
              (grob-interpret-markup grob
                                     (markup #:center-align #:fontsize -2
                                             #:musicglyph "noteheads.s2cross"))
              -2.3
}
%%


This works fine, writing "\speak c4" for instance.


However, I'd like to be able to parameterise the position of the cross which is 
hard-coded as -2.3, so that I can write "\speak #-3.8 c" for instance.  I've 
tried a couple of ways to write it, but I can't find one that works.  I suppose 
that I will need something like "lambda (grob posn)" to define the parameter 
for use at the end, but I can't see how to get the value of posn from the 
LilyPond source into the Scheme procedure.


Help?


Thanks,
Paul
