Yes, I know that there are more appropriate symbols, but I have to conform as
much as possible to the original layout, which uses superscript “o”
everywhere. Indeed this makes sense since the little “o” is the last letter of
every abbreviated word: “Violin_o_ prim_o_” and “Violin_o_ second_o_”, so I
ended up writing something like this (inside \markup):

\concat { "V." \hspace #-0.4 \normal-size-super o "I." \hspace #-0.6 \normal-
size-super o }

which produces an output very similar to the original.


Of course, what it means to “conform as much as possible to the original 
layout” is the question at hand.  If purely visual, your code is 
correct; if purely semantic, “vº1º”/“vº2º” is correct (however the font 
displays that); if both together, then a font with appropriate letter 
and numeral forms is needed.

Improving this "Markup anywhere" snippet

[Colin Baguley]

I wonder whether any of you Lilypond wizards could help me work out how to
improve my Lilypond scores.
Most of my embellishments come from reading/copying bits of code from this
forum - but I admit I don't always fully understand why things work.
However, I have this 'snippet' which I call "Markup anywhere", which
basically allows a markup to be added without disrupting any of the
positioning of other items.
What I would like is to know how it can be improved - so that I can use it
without copying large chunks of code whenever it is required. The amended
markup is demonstrated here:-

c1^\markup { \null \with-dimensions #'(0 . 0) #'(0 . 0)
\translate #'(-10.0 . -4.0)
\override #'(font-name ."Tahoma bold italic")
\fontsize #-2 \with-color #(x11-color "LimeGreen")
\box \box \whiteout
  "Put your text here"

Could this be streamlined and generalised somehow, and yet still be able to
accept various variable to alter position/colour etc

I've attached a lilypond file which demonstrates what I mean.

Just as a side note - why does the \whiteout not work perfectly?

Thank you for reading this and I appreciate any thoughts, amendments, and
suggestions.

Hi Colin,

                \fontsize #-2 \with-color #(x11-color "LimeGreen")
                \box \box \whiteout
              "Put your text here"

Could this be streamlined and generalised somehow, and yet still be 
able to accept various variable to alter position/colour etc
\null \with-dimensions ... seems strange: \null produces an empty 
markup, and _then_ the actual command begins. So you can simplify to


\markup \with-dimensions-from \null \translate .


Just as a side note - why does the \whiteout not work perfectly?


For the whiteout, try specyfing

\override TextScript.layer = 1000

in the music or in the \layout { } block to make sure that text scripts 
are put in the foreground and do not lie under other layout objects.


Does this help already?

Unfortunately, SpacingSpanner options are quite buggy currently.

https://gitlab.com/lilypond/lilypond/-/issues/2630
https://gitlab.com/lilypond/lilypond/-/issues/4493

There is always the good old hack of inserting
"s16" before the altered note to avoid the collision.

Well, how should they? At the point the skip-of-length is evaluated the repeats 
are not yet unfolded. To achieve what you want we could have some mechanics 
where skip events could have an element property, and have the handling be done 
by the engraver.

In recent versions, like version 2.23.6 which you are using, you can use

That's much better than my hack, which involved a few X-offsets.  Thanks!

Complex three-voice left hand

[Knute Snortum]

Hello again.

I am having difficulties engraving a complex three-voice lefthand
measure.  Chopin (bless his heart!) has written some "impossible" note
lengths.  I have two ways that get close to engraving the measure as
Chopin wrote it, but not quite.

Attached is the measure I want to engrave, then my two attempts, then
the input file that created the two attempts.  Any suggestions would
be appreciated.

Re: Complex three-voice left hand

[Valentin Petzel]

Hello Knute,

the thing is that you do not have three voices, but four:
The bass, going ef2 ef4, the treble going df2 df4, the tenor going g4 g gf and 
the alto having that eigth note pattern.

See the appended file for how I’d do it (using forced hshifts, because I do not 
want to bother with finding the correct voice configuration to get some 
offsets).

Cheers,
Valentin

Re: skip-of-length and \unfoldRepeats

[Valentin Petzel]

I’m sorry if this has come across in the wrong way. English is not my native 
language, so sometime I do not get the tone right and sound ruder than I 
intended. I did by no means indent to reprimand you for your legitimate 
question.

With the amazing Jean’s comment #skip-of-length should probably loose all use 
from a users perspective, as the \skip \music command is easier to use and 
more stable (this one basically does exactly what I said previously: It 
creates a SkipMusic event which takes the provided music as it’s element. Thus 
music functions like unfoldRepeats can still access this music as the skip is 
only created during translation (at which point all music functions are 
already evaluated)).

Valentin

OK, how did you search exactly?  Where did you look?  What have you

Werner, the documentation of \skip on music is a ticket
at the moment.

https://gitlab.com/lilypond/lilypond/-/issues/6245

Given that I am not surprised if people don't find it.
A docstring is not easy-to-find nor sufficient documentation.
It's just that in unstable releases it happens to
have undocumented features like that -- of course,
they should get documented before the stable release.
