Reverting TextSpanner properties

[Andrew Bernard]

I have a text spanner set up nicely to do sul ponticello -> nat. All works
beautifully. But how does one revert the overrides use to achieve this to
go back to a plain text spanner without undoing each and every line? Can't
you just revert bound-details?

Searching the list archives did not reveal anything for me. Perhaps a poor
choice of search keywords.

I hope this is not one of those cases again where I should not be using
braces in the definition, but it won't compile if I don't.

Thanks! Sure, what you posted wasn’t "minimal"… but at least it
worked, unlike the last time (where you had copied only a piece of the
code and we couldn’t compile it on its own), so I appreciate your

Yes, exactly. See below for an example of how I would do it; as you
can see, there are a _lot_ of variables.

Well, since you’re starting in the middle of the score, it doesn’t
make sense to print a Time Signature like if it was the beginning.
However, this will also remove new Time Signatures, so if you need to
change \time in your divisi section, you’ll need to use something
else.

Just remove (or comment, by adding "%" at the beginning of the line)
my \remove line, and you’ll see the difference.

The only way to print a name for a group of staves is to (logically)
group them as a StaffGroup… (Or a GrandStaff, or ChoirStaff, or
PianoStaff, well you get the idea.)

As you may have noticed, I had to remove (or comment) the individual
names for each divisi staff; otherwise the name for the whole
StaffGroup would be added to these names and it would be messy.

Well, if you need to use your markup several times, you can put it in
a variable as well.

Here is how I would type your example, using many variables (and no
\tags, like I did earlier). As you can see, everything with notes is
defined first, and _then_ comes every structural information: what
should be printed where, in which group, coming after this and before
that, etc. I think it’s a bit cleaner that way.

Please also note that I created two new contexts, miniStaff and
miniStaffGroup (modified from Staff and StaffGroup), to avoid using
\with {…} too much.

[ . . . ]

The melody is hidden but ties and slurs are quite visible.

I think that making objects transparent is going to be the solution,
but am not sure what objects I’m looking for:


Before getting to transparency, know that there are several ways to 
solve the problem of disparate timing in lyrics.  One option is to use 
explicit durations in the lyrics rather than use \lyricsto.  This lets 
you customize the timing per stanza and gives you the most freedom at 
the cost of added verbosity while entering lyrics.  If you have stanzas 
with wildly different timing, this is probably the best option as it 
saves on having to create voices per stanza.


A second option is to stick to a single voice for all stanzas but make 
use of melismata either implicitly via ties and slurs or explicitly via 
placeholder syllables.  For instance, your half note could be written as 
two, tied quarters, which would accommodate both stanzas.  For the 
second stanza, you need only `\set ignoreMelismata = ##t` to be able to 
assign more lyrics as needed.  This approach tends to be best if you 
have only a few variations in timing between stanzas, as it allows you 
to share the majority of the timing in a single Voice.


A third option is to use a NullVoice to specify timing.  This does not 
render any notes in the staff and does not require embedding the 
explicit durations within the lyrics.  This may be handy for cases where 
you would prefer to reuse lyrics variables against different timing, or 
if you simply do not prefer to use explicit durations.


Lastly, you can use a normal Voice but hide its content as you have 
mentioned.  There are a few challenges with this approach.  Firstly, you 
need to set \voiceXxx appropriately to accommodate both voices even 
though one will ultimately be hidden.  Secondly, the hidden voice will 
still take up space in the layout which may produce unexpected spacing.  
Lastly, there are a number of grobs that can appear as part of 
processing the music.  As you have found, \hideNotes is not sufficient.


NOTE: I noticed that in your snippet you included braces around music 
after \hideNotes.  These are superfluous, as \hideNotes does not take 
any arguments.  I am not certain whether it was your intention that the 
effect of \hideNotes only applied to the music expression in braces.  
But for your reference, you need to manually include \unHideNotes to 
reinstate things.



Is it something like this `\override NoteHead.transparent = ##t`?


Yes.  Although, `\hide Grob` is shorthand for `\override 
Grob.transparent = ##t` for any grob, so you might consider it for 
brevity if you are going to go down this path.  The Internals reference 
can be a handy guide for looking up the various grob names: e.g. Tie, 
Slur, PhrasingSlur.


Be aware that setting transparent to true only makes the grobs 
invisible; the grobs will still occupy space within the layout.  In some 
cases this is fine, but hidden grobs can result in what appears to be 
extra whitespace where the grob would have been.  If this is a problem, 
you can use `\omit Grob` instead if it is your desire that the grobs 
should both be invisible and take up no space.  (This second command is 
shorthand for `\override Grob.stencil = ##f` if I am recalling 
correctly.)

   \new Voice = "chorus" {

This appears to raise the top system without moving anything else;
specifically, without moving the other systems upwards in proportion.
OTOH running LP a second time with smaller margins (and stealing
a page) redistributes the staves automatically. It also takes care
of page numbers etc.

(BTW it might sometimes be more tasteful to steal pages two by two,
ie as double spreads.)

One more thing. I wanted the markup center instrument name for Violin 1 a4
div which you did perfect. But, you say I hackish a bit with making the
StaffGroup in my violin variable. Well, how else would you be able to center
a instrument name like you did if it wasn't a StaffGroup? What if I kept all
instrument staffs separate and added them instead? How could you hide all
instrument  names and replace with centered a4 divisi without Group? I feel
like I did not bad :))

Please. in a simple MWE how can you have a group of string staffs like that
without StaffGroup but also have shortInstrumentName = \markup
\center-column {Vl. "(div. a 4)"} for each staff line separate?

Well, you’re using something a bit unusual : you’re actually starting
a new StaffGroup _inside_ the variable that’s normally used for a
single staff (your first violins) alone.
It’s not impossible, but it’s still a bit hasardous.

So, if you want your "main" Violin1 to keep playing while all of this
is happening, you have to include it as a simultaneous voice, like I
did in the corrected version of your code below.

OK, this is where it become tricky. Because of your rather unusual
hack, _all_ of the divisi part are stored in _one_ variable (where we
usually prefer to define lots of different variables, and then use
these whenever we want). So we have to start with your huge variable
with all the staves inside, and then select the ones we want or filter
the ones we don’t want. LilyPond has a mechanism for that: the \tag
command, that allows you to mark one music expression and everything
inside. See 
http://lilypond.org/doc/v2.19/Documentation/notation/different-editions-from-one-source

Oh, one other thing: you don’t need to copy all your definitions
(global, scoreAViolinI etc.) in every file! Just put them all in one
file, that you can call, for example, "variables.ly":

% file: variables.ly 
global = {…}
scoreAViolinI = {…}
etc.
%%%

And then in another file you can just type :

 file: score.ly %

\include "variables.ly"
\header { title = "Full Score" }
\score {
  \new StaffGroup <<
 \new Staff \scoreAViolinI
 \new Staff … etc …
  >>
}
%

And then you can have other files such as

%% file : solo_part.ly 

\include "variables.ly"
\header { title = "individual part" }
\score {
  \new Staff \scoreAViolinI
}
%%

Anyway. Here’s my version of your code, I’ve used tags and added some

Hello. Not only did I literally include the files as attachment files, which
could not be easier, I also said I am sorry but I do not know how to proceed
so clearly this was the best I could do. Other than not using Liillypond and
not posting for help, I did all work that I could do make helping me easy. I
hope someone else then would kindly download my files and compile them in 5
seconds to help me. I think the code is quite minimal enough if you see 2
files total in body and in attachment. Yes not "MWE" but I think my attempt
is not the most horrible. Thank you. Maybe I should not have body copied
text to scare people away. Obviously you saw the code and felt like MWE was
better. Sorry. In this case if you actually look at divisi problems, it
makes sense. Especially for beginners? 

Just download my ly files please and it's magic :)) all ready for help. MWE
as best I could let's.

You need to change the nonstaff-relatedstaff-spacing so that the 
baselines between the ChordNames and Staff align.  The key is setting 
padding to a large enough negative number, which permits the stencils to 
overlap.  You will still need an additional extra-offset if you want the 
text to sit on the next lower staff line:



\version "2.19.82"
<<
  \new ChordNames \with {
\override VerticalAxisGroup.nonstaff-relatedstaff-spacing =
  #'((basic-distance . 0)(minimum-distance . 0)(padding . -10))
\override ChordName.extra-offset = #'(0 . -1)
  }
  \chordmode { c1 | dis1:m | ees1/g }

That is far too much code for my liking.

Please create a MWE. Chances are that while doing it you'll find a solution to 
your problem.

The code you attached is very obviously NOT a MWE.

ChordNames on Staff

Hi Werner,

currently the code hijacks Glissando. I.e. the default glissando is no
longer printable.
I don't feel such a workaround should be in the docs.

Though, I'd like to come to a behaviour where "Finger-glissandos" are
possible without disturbing default-glissando (between NoteHeads)
That would be a nice amendment for our docs, not only for the harp,
but for guitar, violin, etc

I'll have to find a way to create glissandos and select properly.

For the creation part I've found that I can add additional glissandos
with glissandoMap. See:

val = 0

{
  \override Glissando.after-line-breaking =
  #(lambda (grob)
(ly:grob-set-property! grob 'extra-offset (cons 0 val))
(set! val (1+ val)))

  \set glissandoMap = #'((0 . 0) (0 . 0))
  c'\glissando f'
}

Is it safe to rely on it, or is it rather bug-using?

Cheers,
  Harm

How to fix this divisi please

[Reggie]

Hi. I have put together as much as I can to truly do my best. I hope I am
able to get some help to learn why I am wrong. I have a few questions. One,
how can I input notes in Violin in the empty measures below divisisi? I
don't understand where to insert in my code please. Second, how can I put a
center group name like my attachment image for my strings in my code please.
Finally, how can I create a violin 1 part so each part shows the violin 1
and then only the "appropriate" divisi for each part only? I don't
understand this engraver at all. Each violin one part has all four divisi
staffs. I'd like separate. Thank you for the help. I have included all my
files for help.,

And you can also use \offset to move it relative to its default position:

Guile 1.8 (the main version of Guile working with LilyPond) has 8-bit
characters and strings.  There is ly:wide-char->utf-8 which might work

To that point:

My solution was… unconventional, shall we say… But it solves the problem in

Is there a more conventional solution with the same solution coverage?
Better yet, is there any solution that will work 100% of the time?

Yes, that’s one of the reasons I used the quotes around "must"…  =)

Thanks,

Scheme char issue

[Leo Correia de Verdier]

Dear list!

The following code is not compiling as I think it should. (I think it should 
output a square root sign, it should be valid scheme code for that)

\version "2.19.82"
\void #(display #\x221A)

Is it because I’m stupid, some known issue or something else? Do you know about 
some workaround?

Thanks a lot!
/Leo

Re: text block as spanner

[Leo Correia de Verdier]

Thanks a lot to all for the help and all code you’ve written!
I included Thomas'/Harm's multiple-text-spanners-via-id from February third.

This is what I ended up with:

\version "2.19.80"

\include "multiple-text-spanners-via-id.ly"

longTextInstr =
#(define-music-function (alongtext)
   (string?)
   #{
 -\tweak stencil
 #(lambda (grob)
(let* ((grob-X (interval-length
(ly:stencil-extent (ly:line-spanner::print grob)
X)))
   (layout (ly:grob-layout grob))
   (props (ly:grob-alist-chain grob
(ly:output-def-lookup layout
  'text-font-defaults)))
   (padding .5))

  (ly:text-interface::interpret-markup layout props
#{ \markup {
  \override #(cons 'line-width (- grob-X padding))
  \wordwrap-string #alongtext }
#})
  ))
 \=10\startTextSpan
   #}
   )

wrapLongTextInstr = \=10\stopTextSpan

%{example

\layout {
  \context {
\Voice
\remove #"Text_spanner_engraver"
\consists \alternateTextSpannerEngraver
  }
}

\relative c' {
  c4 d -\longTextInstr "this is a long instruction to be printed over a few
notes"
  e f c d
  g2 e \wrapLongTextInstr
  d
}
%}

A bold workaround is to define the whole infrastructure for
TextSpanners with new/renamed events (class and type), grobs,
engravers and
start/stop-commands.


I forgot to point to a limitation
The provided 'text-spanner->text' doesn't care for line-breaks.


To clarify, 'text-spanner->text' has nothing to do with multiple
TextSpanners.
It's a stencil-override. special line-breaking behaviour is not coded,
though.

There is this:

Looks we have the same conversation every few years lol


:)

Your approach is far less invasive, so preferable.

Not sure if anything needs to be updated.



Ideally, this sort of thing could be added to the code base to avoid
the tangled history!  I never went further with this because of the
effort to rationalize spanners (GSoc?)  I figured adding something
like this would be like adding balconies onto balconies, or whatever
the architectural analogy would be.

The fix mentioned here
http://lists.gnu.org/archive/html/lilypond-user/2017-11/msg00016.html
should be applied, then it still works.

Though, I noticed a little problem here and in scheme-text-spanner
from our regtests, too:
Usually one can set the direction via direction-modifiers, i.e. for
_\startTextSpan the TextSpanner is printed below. This does not work.

The direction may be catched in listener and applied to the grob in
process-music.
So I did in the attached file, not sure whether it's the best fix ...


Thank you kindly--I now see all the colored lines in their irrelevant
glory!  I missed the change you mention and would have spent I don't
know how much time looking for a solution.


Thanks,
 Harm


Best,
David

Hi Craig,

For example:

\version "2.19.82"

{
  c''4   \once \override BreathingSign.Y-offset = 4 \breathe
  c'' c'' c''

That's neat!

Added to my snippet collection.

Thank you,
