\assertBeamSlope

[Chad Linsley]

Can anyone demonstrate how to use this music function?

\assertBeamSlope

I've seen an example of \assertBeamQuant in the Regression Tests but not
\assertBeamSlope.

Re: Small note between staves as time signature

[Lukas-Fabian Moser]

Hi Jakob,

The Danish book of chorales to accompany the official hymnal uses a 
peculiar "time signature" (which isn't really a time signature) for 
some hymns.


It's a small note, in this case a 텞  but elsewhere its a compound 
signature like 텞♩, to indicate the metre.

Maybe also use an actual TimeSignature living in a Dynamics context?

\version "2.24.0"

#(add-simple-time-signature-style
  'note
  (lambda (frac)
    (let ((den (cdr frac)))
  #{ \markup \tiny \note #(ly:make-duration (ly:intlog2 den)) #UP #})))

\layout {
  \context {
    \Dynamics
    \consists Time_signature_engraver
    \override TimeSignature.break-align-symbol = #'key-signature
    \override TimeSignature.style = #'note
  }
  \context {
    \Staff
    \remove Time_signature_engraver
  }
}

\score {
  \new PianoStaff <<
    \new Staff {
  \key d \major
  \after 1*6 { \break \time 2/2 }
  \repeat unfold 100 << d'4 \\ a4 >>
    }
    \new Dynamics {
  s1*25
    }
    \new Staff \with { \clef bass } {
  \key d \major
  \repeat unfold 100 << fis4 \\ d4 >>
    }
  >>
}

Hi Juergen,

Works perfectly! Thank you very much.

I can guarantee you I would never have figured that out on my own!

If anyone has any idea what this kind of notation is called, do let me 
know :)


Best wishes,
Jakob

What breaks the layout is not the variable bindings per se of course, but the 
ly:grob-property calls, and that's because you are asking for information too 
early. At the moment after-line-breaking is
run, page layout is not done yet. Asking for the Y-extent of the brace 
indirectly triggers calculations of the distance between staves while the 
backend is generally not yet in a state where it is
able to compute them correctly. The X-extent of SystemStartBrace is unset 
(https://lilypond.org/doc/v2.24/Documentation/internals/systemstartbrace) which 
means LilyPond uses the default of computing
it from the grob's stencil, so when you ask for the X-extent, it will try to 
compute the stencil, and thus the height, leading to the same problem. 
Similarly, the X-offset is based on side positioning
(ly:side-position-interface::x-aligned-side) so it will request the stencil.

On the other hand, the Y-offset is always 0, so you don't get problems, but 
it's not very useful either.

Re: Othering??

[Arjen]

My guess:

"Othering" is the visual result of a word of 8 letters ending in 
".ing" (e.g., Building) partly being overwritten by the word "Other".
This can happen when a progression line is repeatedly overwritten by 
ending it with a lone carriage return character (CR, ASCII 13) causing 
the cursor to return to the beginning of the same line on the terminal 
screen. Only when a line feed (LF, ASCII 10) is received, the cursor 
will move one line down.

\Loading
|Loading
/Loading
Other

To find out which word exactly is overwritten each time, try capturing 
the output in a file. On unix-like platforms there are several 
techniques for this, redirection comes to mind.

DeepL translate Othering in French by altérisation, which is not
really French either (the right word would be altération)

I suppose this is related to the use of sharp, flat and other beccare
