Try using:

 \override TextSpanner.bound-details.left-broken.text = ""

like this:

\version "2.22.2"

mybar = { c4 d c d }
\score {
  \relative c' {
\mybar \mybar \mybar
\override TextSpanner.bound-details.left.text = "poco a poco
accelerando"
\override TextSpanner.bound-details.left-broken.text = "" % <-- add this
c \startTextSpan d c d
\mybar
\mybar \break
\mybar
\stopTextSpan
\tempo "Tempo I"
\mybar \mybar \mybar \mybar
  }

Hi Bevan!

I think what you are looking for is:

\override TextSpanner.bound-details.left-broken.text = ##f

textSpanner - disable repeat of text on new line

[Bevan Broun]

Hi All

When using a text spanner I get the text repeated after a line break,
followed by new dashes. Can I disable getting the repeat of the text and
only get dashes on the new line? I have a case where the repeated text is
banging up against some other text and it would be clearer with just dashes
on the new line.

Thanks

  \relative c' {
\mybar \mybar \mybar

c \startTextSpan d c d
\mybar
\mybar \break

Thanks, for your detailed explanation.
To get around it one could do:

#(define (add-to-interfaces iface name grob-descriptions-alist)
  (map
(lambda (x)
  (if (eq? (car x) name)
  (let* (;; Use `list-copy' like `completize-grob-entry' in

 (ifaces-entry
  (assoc-get 'interfaces meta-entry)))
(set! ifaces-entry (cons iface ifaces-entry))
(set! meta-entry (assoc-set! meta-entry 'interfaces ifaces-entry))

Well, I need to directly connect two notes/rests, probably with a lot
of other stuff in between.
For this connection several styles are possible
(1) A straight line (maybe dashed or dotted)
Thus TextSpanner was my first thought. Alas, in most cases the line will
not be horizontal so I need some stencil override anyway.
Pretty simple, though, can be made to work automatically.
(2) A curve, probably a s-curve.
Thus current thread topic
(3) A multiple kneed line:
 
|___||
 v
(the graphic will likely not survive mail delivery unchanged, though
maybe you can imagine it)

To summarize, all three possibilities will need other stencils.
If control-points are available (Slur) it is probably not hard to get to (1).
For (2), a Slur may be good out of the box, otherwise vshape will always work.
For kneed lines (3), make connected-path-stencil may work.

All three possibilities can be made to work with TextSpanner and Slur.
I think I have to experiment, what works out better.

  Harm

\shape works because it's an override/tweak to the control-points
property, and your code reads this property.

\vshape is implemented with separate grobs, ControlPoint and
ControlPolygon. This is so that you can override their basic
properties (color, layer, thickness, ...) independently from the
bezier grob. They are created by the Show_control_points_engraver,
which acknowledges bezier curve grobs and reads their
show-control-points-property. Your custom TextSpanner isn't
recognized because it doesn't have the bezier-curve-interface,
and this is what Show_control_points_engraver acknowledges.
Do you have a specific reason to use a TextSpanner? How
about using a Slur?

What do you mean with 'dedicated grobs'?

> What is the context of your question?

I'm working on documentation for all grobs, and I also add cross
references from one grob to similar grobs (if it makes sense).  While
doing that I noticed that `TextSpanner` has no auxiliary grob for
aligning.

That sounds like you have

instead of

I think (cannot verify this weekend) that this is only going to work in 2.23 
thanks to \ottava having been converted to a stream event. In 2.22, try

\once \override Staff.OttavaSpanner.outside-staff-priority = 0
\ottava 1

Hi Kenneth,

That line was in the file that you sent. I had to comment it out as

Re: How to do TextSpanner + markup + override vertical placement all at the same time?

[Kevin Barry]

Hi Kenneth,

I think you can fix the problem with the relative positioning by
setting the 'outside-staff-priority, e.g.:

\tweak #'outside-staff-priority #0 \ottava 1

will cause the ottava marking to be put closer to the staff than the text span.

[Kenneth Wolcott]

Hi;

  I figured out how to get the formatting of the "a tempo" and "rall."
merged with the text spanning; but I still can't seem to figure out
how to get the "a tempo" to be above the ottava marking.

  Updated screenshot attached.

  Attached full Lilypond code as well.

Thanks,
Ken

Re: `\textLengthOn` for `TextSpanner` grobs

[Jean Abou Samra]

Le 30/11/2021 à 21:55, Jean Abou Samra a écrit :


Basically, extra-spacing-width etc. work on items, and
not on spanners. If you want a spanner to occupy space
at its bounds, the state of the art is that you have
to create "stub" items.

I won't have the time to work on it more, sorry.



PS: It might be a good idea to open a tracker issue.

Re: `\textLengthOn` for `TextSpanner` grobs

[Jean Abou Samra]

Le 28/11/2021 à 16:10, Werner LEMBERG a écrit :

please have a look at this example

```
{
\set Score.skipBars = ##t
\override TextSpanner.bound-details.left.text = "poco a poco tempo I"
\override TextSpanner.bound-details.right.text = "Tempo I"
R1*4\startTextSpan |
R1\stopTextSpan
}
```

What is the equivalent of `\textLengthOn` for `TextSpanner` grobs so
that the multi-measure rest gets properly stretched horizontally?

Use

   \override TextSpanner.minimum-length = 30
   \override TextSpanner.springs-and-rods = #ly:spanner::set-spacing-rods

Thanks.  Alas, doesn't work correctly for broken spanners:

```
\paper {
   line-width = 100\mm
}

{
   \set Score.skipBars = ##t
   \override TextSpanner.bound-details.left.text = "poco a poco tempo I"
   \override TextSpanner.bound-details.left-broken.text = ""
   \override TextSpanner.bound-details.right.text = "Tempo I"
   \override TextSpanner.bound-details.right-broken.text = ""
   \override TextSpanner.minimum-length = 34
   \override TextSpanner.springs-and-rods = #ly:spanner::set-spacing-rods

   R1*4\startTextSpan | \break
   R1*4\stopTextSpan |
   R1 |
}
```

I also wonder whether there is a solution (or should be a solution)
that doesn't need manual entering of a minimum length value that can
only be found by trial and error.  For example, wouldn't it be
sensible to have the possibility of

```
\override TextSpanner.bound-details
 .left.extra-spacing-height = #'(-inf.0 . +inf.0)
\override TextSpanner.bound-details
 .right.extra-spacing-height = #'(-inf.0 . +inf.0)

Thanks.  Alas, doesn't work correctly for broken spanners:

```
\paper {
  line-width = 100\mm
}

{
  \set Score.skipBars = ##t
  \override TextSpanner.bound-details.left.text = "poco a poco tempo I"
  \override TextSpanner.bound-details.left-broken.text = ""
  \override TextSpanner.bound-details.right.text = "Tempo I"
  \override TextSpanner.bound-details.right-broken.text = ""
  \override TextSpanner.minimum-length = 34
  \override TextSpanner.springs-and-rods = #ly:spanner::set-spacing-rods

  R1*4\startTextSpan | \break
  R1*4\stopTextSpan |
  R1 |
}
```

I also wonder whether there is a solution (or should be a solution)
that doesn't need manual entering of a minimum length value that can
only be found by trial and error.  For example, wouldn't it be
sensible to have the possibility of

```
\override TextSpanner.bound-details
.left.extra-spacing-height = #'(-inf.0 . +inf.0)
\override TextSpanner.bound-details
.right.extra-spacing-height = #'(-inf.0 . +inf.0)
```

in combination with the `extra-spacing-width` property to get
automatically the correct value(s)?

Re: TextSpanner to end of bar / end of piece

[Lukas-Fabian Moser]

Hi Harm,

So this seems to mean that right-broken.text should be changed by a 
hook that determines if we are at a line break. I'llt try to see if I 
can figure out how to do this.


It seems to suffice to copy right.text into right-broken.text only for 
the last bit of a broken TextSpanner:


   \override TextSpanner.after-line-breaking =
    #(lambda (grob)
   ; Copies bound-details.right settings to bound-details.right-broken
   ; for the last part of a broken spanner.
   ; This is needed because, if to-barline = ##t and the last part ends
   ; at a line break, the values from right-broken are used.
   (let*
    ((orig (ly:grob-original grob))
 (siblings (if (ly:grob? orig)
   (ly:spanner-broken-into orig)
   '(
    (if (not (null? siblings))
    (if (eq? grob (car (last-pair siblings)))
    (ly:grob-set-nested-property!
 grob
 '(bound-details right-broken)
 (ly:assoc-get 'right (ly:grob-property grob 
'bound-details)))




Thanks for the hint, Harm!

Hi Harm,

Though, if the TextSpanner does not end at line-end you'll need 
different settings.

Probably doable by some scheme-coding ...


Ah, yes. It seems that with to-barline, the right-broken.text is used at 
the end of the line. Thanks!


So this seems to mean that right-broken.text should be changed by a hook 
that determines if we are at a line break. I'llt try to see if I can 
figure out how to do this.

Hi Lukas,

below works for me:

  \override TextSpanner.bound-details.right.text = "R"
  \override TextSpanner.bound-details.left.text = "L"

  <>\startTextSpan

TextSpanner to end of bar / end of piece

[Lukas-Fabian Moser]

Folks,

two questions about the behaviour of textSpanners:

First question:

If a TextSpanner ends at the beginning at a bar which happens to be a 
line break, then


- with TextSpanner.to-barline = ##f, I get the left-broken.text and the 
right.text immediately after one another at the beginning of the second 
system,


- with TextSpanner.to-barline = ##t, I get no artifacts in the next 
line, but right.text is missing in the first system.


What I want: The text spanner should end at the last barline of the 
first system, but right.text should be printed.


Second question: Is it possible to let a TextSpanner end precisely at 
the end of a piece (last barline) with right.text being printed?


I can approximate the desired behaviour in both cases by letting the 
TextSpanner end a very short amount of time before the actual end of the 
bar, but that feels conceptually wrong and also does not yield the 
correct position of "R".


Lukas

TextSpanner implements the same [relevant] interfaces:

Thanks for chiming in.  I don’t really follow, though.  I poked around a bit

broken TextSpanner

[bobr...@centrum.is]

Somewhere in the docs I ran across this structure (v2.20 or v2.22).  I have not 
been able to find it again:


  \override TextSpanner.bound-details.left.text = \markup{\dynamic "mf" "dim."}
  \override TextSpanner.bound-details.right.text = \markup{ \dynamic "pp" }
  \override TextSpanner.breakable = ##t

An example showed how this produced a mezzo-forte with 'dim.' at \startTextSpan 
and after the line break the end note with 'pp' at \stopTextSpan.

What I get is "mf dim."..'pp'

line break

'mfdimpp' all jammed together and overlapping under the note after the break.


Is such a thing possible as in the above code or do I need to work around this 
some other way?

I'm a little out of practice, but here's my attempt at automating:
\version "2.21.5"

#(define (patterned-markup glyph)
   (lambda (grob)
 (let* ((stil (ly:line-spanner::print grob))

(spanner-angle (atan (/ (interval-length spanner-extent-Y)
   spanner-length-X)))
(spanner-angle (degrees->radians spanner-angle))
(glyph-stil (ly:font-get-glyph (ly:grob-default-font grob) glyph))
(glyph-stil (ly:stencil-rotate glyph-stil spanner-angle 0 0))
(glyph-extent-X (ly:stencil-extent glyph-stil X))
(glyph-length-X (interval-length glyph-extent-X))
(reps (round (/ spanner-length-X glyph-length-X

 (ly:grob-set-property! grob 'stencil new-stil)
 (loop
  (1+ x)
  (ly:stencil-combine-at-edge new-stil X RIGHT glyph-stil 0.0)))

Hi Artur,
This is not exactly what you ask for but you could do something like:

\version "2.22.0"
{
  c'1
  -\tweak X-extent #'(0 . 0)
  ^\markup\pattern #25 #X #0 \musicglyph #"scripts.turn"
  1 1 1 1 1 1 1 1 1

Add a vertical line to TextSpanner

[Thomas Morley]

Hi,

I'm trying to add a vertical line to the left side of a TextSpanner.
This line should connect the TextSpanner with the middle line of the
StaffSymbol.

Here a manual done example code:

{
  \once \override TextSpanner.bound-details.left.text =
\markup
  \with-dimensions #'(0 . 0) #'(0 . 0)
  \draw-line #'(0 . -2.85)
  b1\startTextSpan
  b1\stopTextSpan

  \once \override TextSpanner.bound-details.left.text =
\markup
  \with-dimensions #'(0 . 0) #'(0 . 0)
  \draw-line #'(0 . -4.5)
  b1\startTextSpan
  b''1\stopTextSpan

  \once \override TextSpanner.bound-details.left.text =
\markup
  \with-dimensions #'(0 . 0) #'(0 . 0)
  \draw-line #'(0 . -5.7)
  b1\startTextSpan
  b''1^!\stopTextSpan
}

Could this be done automagically?

Thanks,
  Harm

This is where providing an example of what you have tried would be

A note is allowed to be the end of one span and the beginning of

Simply adjust the left and/or right padding of the spanner. You can
look it up in the NR and Internals reference.

Re: TextSpanner usability improvements

[Martín Rincón Botero]

Dear all,

in case there are people like me interested in having a basic syntax for
inputting text spanners, I wrote three simple functions for that matter:
\textSpan, \textSpanArrow and \textSpanDoubleArrow. They replace in
practice following overrides with user input:

\override TextSpanner.bound-details.left.text
\override TextSpanner.bound-details.right.text
\override TextSpanner.style
\override TextSpanner.bound-details.right.arrow
\override TextSpanner.bound-details.left.arrow

The syntax of these three functions is:
\textSpan "text" #'linestyle "text", and are used in combination with
\startTextSpan and \stopTextSpan. Overrides and tweaks can still be used,
preferably after and not before, so that what you change is not changed
again by these functions.

\version "2.20.0"

textSpan = #(define-music-function
   (parser location leftmarkup style rightmarkup)
   (markup? symbol? markup?)
   #{
\override TextSpanner.bound-details.left.text = \markup { \upright
#leftmarkup }
\override TextSpanner.bound-details.right.text = \markup { \upright
#rightmarkup }
\override TextSpanner.bound-details.left-broken.text = ##f
\override TextSpanner.bound-details.right-broken.text = ##f
\override TextSpanner.style = #style
\override TextSpanner.bound-details.right.arrow = ##f
\override TextSpanner.bound-details.left.arrow = ##f
   #})

textSpanArrow = #(define-music-function
   (parser location leftmarkup style rightmarkup)
   (markup? symbol? markup?)
   #{
\override TextSpanner.style = #style
\override TextSpanner.bound-details.right.stencil-align-dir-y = #CENTER
\override TextSpanner.bound-details.left.stencil-align-dir-y = #CENTER
\override TextSpanner.bound-details.right.arrow = ##t
\override TextSpanner.bound-details.left.text = \markup { \upright
#leftmarkup }
\override TextSpanner.bound-details.right.text = \markup { \upright
#rightmarkup }
\override TextSpanner.bound-details.left-broken.text = ##f
\override TextSpanner.bound-details.right-broken.text = ##f
\override TextSpanner.dash-period = 1.0
   #})

textSpanDoubleArrow = #(define-music-function
   (parser location leftmarkup style rightmarkup)
   (markup? symbol? markup?)
   #{
\override TextSpanner.style = #style
\override TextSpanner.bound-details.right.stencil-align-dir-y = #CENTER
\override TextSpanner.bound-details.left.stencil-align-dir-y = #CENTER
\override TextSpanner.bound-details.right.arrow = ##t
\override TextSpanner.bound-details.left.arrow = ##t
\override TextSpanner.bound-details.left.text = \markup { \upright
#leftmarkup }
\override TextSpanner.bound-details.right.text = \markup { \upright

\override TextSpanner.bound-details.left-broken.text = ##f
\override TextSpanner.bound-details.right-broken.text = ##f
\override TextSpanner.dash-period = 1.0
   #})

\relative c' {
  \textSpan \markup { \bold "press." } #'trill \markup { \italic

Exactly, me neither. Forcing the default to be empty text without giving the 
user the chance to give input right there where the music is, is almost as 
undesirable as having “left text” and “right text” as defaults that you have to 
manually override.

In principle, I would support this as well.

Hi Martin,

in general I'm more with Aaron.
P.e., I have no clue which default text one could think of for
TextSpanner's left/right-text!?
Otoh, I'd wish we'd have a LilyPond-data-structure to assign a list of

That said, find attached a TempoSpanner-coding.
I'm not sure it's the best approach at all. For sure there's wide room

Well, it seems we already agreed on one satisfactory syntax with the way you

I hadn’t thought about it that way. I certainly give a lot of importance to 
syntax. Perhaps I should try to contribute in that territory somehow. Not a

I suppose the \with construct could be extended to uses it doesn’t have right

Yes, the script I started writing and that you splendidly finished is
a workaround, not a solution. I’m not a programmer, so the day I can

It would be great if such spanners can be implemented!


It is good to have the "non-programmer" perspective.  Mind you, I would 
argue your use of LilyPond and interest in Scheme means you have already 
begun your journey as a programmer.  (:

how can a proposed syntax (for which functions have to be written yet) as

At no point is my suggestion to “all” of these parameters in a function. My 
suggestion is to have a basic function with “sensible” defaults. They can 
always be tweaked or overridden by the user as desired. That’s what \override 
and \tweak are for.

No they shouldn’t. They have to if they want to have a legible code with a 
proper markup tagging.

I also was thinking of the better possibility that \startTextSpan can take 
arguments. The \with function is not meant for data input but for changing 
context properties. And if we’re starting to put text where it actually belongs 
in the music, certainly saying “left-text” for the \startTextSpan function is 
redundant. If \startTextSpan accepts text, \stopTextSpan should accept the 
right part of the text, so that it appears in the correct place in the music. A 
basic (hypothetical) c1\startTextSpan "left" c1 c1\stopTextSpan "right" would 
be a massive improvement in readability. If this function could stop being 
“misused” for tempo variations (if we had tempo spanners), then I suppose the 
italics by default could go away (I can’t think of other reason why they have 
to be italics by default!)

TextSpanner usability improvements (was Re: Scheme predicative types)

is the impossibility to use proper markup syntax for text spanners.


I am uncertain what you mean by "proper" markup syntax.  Even though 
they are called "TextSpanners", the text can be any markup? value:



{ b'4 -\tweak bound-details.left.text \markup \box ?
  -\tweak bound-details.right.text \markup \circle !
  -\tweak font-series #'bold
  -\tweak font-shape #'upright
  \startTextSpan
  a' g'2 | f'4 g'8 a' g'2 | a'1\stopTextSpan }


Your proposed...


\markupSpan { "sul pont." \arrow "sul tasto" }


...while interesting, is invalid syntax and surely not proper.  Perhaps 
you simply meant something that *looks* like it could be valid LilyPond.




[...] In the case of
text spanners, the default has no musical use: a dashed line with no 
text
on either side. The syntax of a text spanner has the serious omission 
of
starting something without user input (\startTextSpan starts what? The 
user

should have an "interface" to give an initial input.


Consider a \textSpan function that has you specify the left and right 
text.  What happens when you only need left-side text?  Is it 
satisfactory for a user to have to say \textSpan "left" ""?  Next, there 
are options for padding and whether the side of the spanner terminates 
in an arrow.  What happens when you need to specify the padding on one 
side and the arrow-type on the other?  Including all of these as 
parameters to a function could make the function unwieldy to use when 
one only needs to specify a few values.  Optional arguments help to some 
degree, but they aren't perfect especially when there is ambiguity of 
types.


The existing interface for TextSpanners requires that one manually 
\override or \tweak properties so that you only specify what you need.  
This may seem cumbersome when adjusting many things, but it is at least 
very clear what is going on.  You certainly don't have to remember which 
argument is which.  And users of TextSpanners should invest in creating 
their own wrappers for commonly used items.  Consider something like 
this:



startRitSpan =
  -\tweak bound-details.left.text "rit."
  -\tweak to-barline ##t
  \startTextSpan

{ b'4 a' g'2\startRitSpan |
  f'4 g'8 a' g'2 | a'1\stopTextSpan }


The result is something that is more succinct to use within the actual 
music, uncluttered by \overrides and \tweaks.  And being reusable 
assists in keeping the overall score consistent.  (It is mildly annoying 
though to have to use \stopTextSpan, but it is probably better than 
polluting the namespace with a whole host of \stop*Span aliases that all 
do the same thing.)


While the above is some defense of the existing interface, there could 
be ways to improve the experience.  For instance, imagine this:



{ b'4 a' g'2\startTextSpan \with { left-text = "rit."
   to-barline = ##t } |
  f'4 g'8 a' g'2 | a'1\stopTextSpan }


I do wonder if my obsession with ly:context-mod? goes too far, but I 
keep finding that the \with {} construct is a great alternative to 
variable argument lists.  There is never any confusion as properties are 
well-named; plus, the construct is quite extensible.




[...] The second issue is the mentioned 2013
issue. Lilypond lacks the possibility of using text spanners not only 
with

a \tempo syntax (which thanks to your script is very well solved now!),
something that makes the "music" in the code more legible (because 
there is
proper markup of musical events) but also to format the whole thing as 
a

\tempo marking in the score (tempo indications are not attached to the
staff but to the system, and horizontally metronome marks are not 
attached
to the first note of the measure but to the time signature above which 
they

are centered, that's why I included \halign properties in the script as
workaround).


That would point to TextSpanners not being the right fit/tool for the 
job.  What we perhaps need is something like a MetronomeSpanner and 
possibly a RehearsalSpanner--connecting MetronomeMarks and 
RehearsalMarks, respectively.  And then we need a way to attach the 
spanner to \tempos or \marks in an equivalent manner as you attach 
TextSpanners to notes.


That approach would better preserve the semantics of the underlying 
elements.  Consuming a \tempo command only to produce a \markup that 
*looks* like a MetronomeMark but is not one leads to issues as you found 
with MIDI.  The Tempo_performer cannot do what it needs to do as it does 
not understand what the \markup means.  That is not to mention that the 
use of \tempo occurs at the wrong moment in the music.  Such a proposed 
MetronomeSpanner would terminate with an actual \tempo command on either 
end at the correct moments.  And the Tempo_performer could be improved 
to understand how to interpolate tempos that are

Thank you Aaron for the explanation. I was trying the make-music solution as

Unfortunately, your solution doesn't allow that:
mySpan = -\tweak bound-details.left.text \etc \startTextSpan

I'm curretly re-writing my shortcuts and configuration files in lilypond. I
try to rationalize it and avoid the massive recourse of independent
shortcuts (for instance, rit=... , moltoRit=... etc.). Maybe that has
already been discussed somewhere else but I wasn't able to find the
solution?

I'm going to bump this, if that's alright. Is there a way to disable

Allowing TextSpanner lines to collide, but not the end text

[michaellee94]

I'm in the middle of editing a score that uses custom TextSpanners (the
Haupstimme and Nebenstimme spanners constructed in
http://lsr.di.unimi.it/LSR/Item?id=843). Sometimes the melodic lines go
above the staff, and in this case, I'd like to make sure that the glyphs
don't collide with the notes, but I don't really care about the invisible
line in between them. I've attached an example of the typical behavior. If
possible, I'd like the positioning of the H and bracket in the right-hand
case to match the positioning in the left-hand case. Would anybody know how
to achieve this? I assume there's a general property of TextSpanners that
allows for it. Thank you for your help!

I think you nailed the root of why I think the naming is confusing. Funnily
enough I do think that the name "padding" is appropriate for Glissandos,
where it is a measure of how much white-space there is between the end of
the glissando and it's notehead. I just don't find it intuitive for
TextSpanners in particular. I agree however that this ship has sailed.

Werner, I looked at the documentation trying to see what I would have
needed to be different in order to be able to find this knowledge on my
own. For me personally it would have been to have the Internals Reference
offer a very concise yet detailed description of the sub-properties of the
bound-details property of the line-spanner-interface
<http://lilypond.org/doc/v2.19/Documentation/internals/line_002dspanner_002dinterface>
.
This is because my workflow in these scenarios is to go to the description
of the object which is giving me trouble, see what interfaces and
properties it has, and from there work out what I need to do. This is also
what the Lilypond manuals suggest
<http://lilypond.org/doc/v2.19/Documentation/learning/properties-of-layout-objects>.
So, if the purpose of the Internals Reference is "to present information
precisely and concisely", for me a precise description would be at the very
least to have a list of it's sub-properties.

I think someone explained to me some time ago (in a similar situation with
an alist of properties although I don't remember specifically with what)
that this is not possible because of the way the documentation is
automatically generated. If this is not possible then a visual example in
this verbose description
<http://lilypond.org/doc/v2.19/Documentation/notation/spanners#using-the-line_002dspanner_002dinterfacehttp://lilypond.org/doc/v2.19/Documentation/notation/spanners#using-the-line_002dspanner_002dinterface>
of the line-spanner-interface would be my next bet: a short snippet that
shows it's effect in a few different grobs would probably be enough to be
able to find it when hunting for a solution.

Do any of the above seem feasible?

Well, that's exactly what happens here.
bound-details.right.padding is the amount of white-space between the
end of the TextSpanner and its right-bound.
Thus the negative value, as opposed to your code going for 'X.
Admittedly, as opposed to other Grob.padding settings no object is
moved, instead the TextSpanner itself changes its appearance.

I _guess_ (without having researched) it's also due to historical reasons:
Going for 'shorten-pair for TextSpanner would have needed additional
code to limit it to certain parts of a broken spanner, whereas
bound-details.left/right/left-broken/right-broken.padding
offers the user a direct method to set whats wished for each end of a
broken TextSpanner.
Thus, replacing the values of
bound-details.left/right/left-broken/right-broken.padding by those
from shorten-pair is not that straight-forward.
Probably the name of the padding-_sub_-property is unfortunate.
Though, I think this ship sailed long time ago.

Btw
\override TextSpanner.padding = 10
_moves_ the TextSpanner, nothing else, as everyone would expect.

Hi Stefano,

There are many threads in the archives about this inconsistency with text
spanners. It's very confusing for users, nad ends up wasting lots of time.
It would be great if this could be unified with the 'shorten' commands of
other objects, but I realise the developers are hugely constrained for time
and resources. Maybe one day.

Why not:

  \override TextSpanner.bound-details.right-broken.padding = 0.25
  \override TextSpanner.bound-details.right.padding = -15

The first to keep the default for right-broken TextSpanner.
(Per default bound-details.right-broken is unset for TextSpanners and
thus copies bound-details.right)
The second to affect bound-details.right.padding as wished.

Hi Rick,

Thank you for your answer. I didn't know that 'bound-details had an X
property. It does what I need but it can get tedious to use because I need
to specify a number from the start of the spanner (or the system if the
spanner is broken into many systems). It takes some trial and error to find
the right number and all that work is undone if the spacing changes.

That however led me to writing this function that offsets the 'X value of
the 'right-bound-info property, which is the procedure that calculates
where the spanner ends. I'm copying it here so it can be used if someone
finds it useful or is searching for a similar question in the future.

Subject: Finetuning TextSpanner beginning and end positions?

Hello again everyone,

I was expecting to be able to use shorten-pair for this in the same way that is 
used with Hairpins, but it doesn't seem to work and I can't seem to find what 
property I need to tweak.

Any pointers?
Thanks for your help,

Re: Reverting TextSpanner properties

[Andrew Bernard]

Hi Reggie,

This is just my personal code for a string quartet I am doing, and my use
case may be a little different to normal, as I have to set it all up to be
able to do SP->NAT->SP continuous as well as plain SP->NAT, and ST->NAT,
and so on, so there are more parts to this than just my initial query MWE.
The code was not really proposed as a general purpose solution for this
string playing technique.

You're more than welcome to it, but perhaps we should work this up into a
more robust and well thought out design pattern for inclusion in the LSR?
Also needs to be parameterized to accept sul ponticello or sul tasto.

Well, it's a matter of

sulPont = -\single \spToNatSpan \startTextSpan
stopSulPont = -\endTextSpan

And then you use \sulPont and \stopSulPont where you now use
\startTextSpan and \stopTextSpan .  I find that more straightforward
than what you use but of course it is slightly less efficient.  But
probably not a measurable difference.

Hello David. I added your suggestions but nothing compiles correctly

It's \stopTextSpan, not \endTextSpan.

Note that if you use \sulPont and \stopSulPont, you would no longer need 
(or want) to use \spToNatSpan explicitly.  Also, you would still need to 
use \startTextSpan and \stopTextSpan to get the basic spanner.

Re: Reverting TextSpanner properties

[Andrew Bernard]

Hello Pierre,

This is helpful. I deduce from this that you can only use revert on
bound-details as a while if you override it as a complete alist to begin
with, not as separate overrides for each sub-property as I had. That's an
important thing to know.

Of course, to revert the other overrides, such as font-size, back to the
system default, that would need a separate revert as well for these. I can
find all the system defaults in the lilypond source code.

I was hoping there may be some sort of \reset command, but this is a
figment of my imagination.

\undo \spToNatSpan ?

Personally, I'd rather tweak \startTextSpan rather than set properties
permanently but that's likely a matter of taste.

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.

Re: Shorten TextSpanner dashed line

[Andrew Bernard]

Hi Davide,

You could play with this:

  \override TextSpanner.bound-details.right.padding = 1

Have a look at the internals reference.

Shorten TextSpanner dashed line

[Davide Liessi]

Hi all.
Is it possible to automatically shorten the dashed line in
TextSpanners so that the line of the first TextSpanner ends before the
left text of the second TextSpanner (and thus the two TextSpanners can
align vertically)?

\version "2.19.82"
{
  \override TextSpanner.bound-details.left.text = "test"
  b1\startTextSpan
  b1\stopTextSpan\startTextSpan
  b1\stopTextSpan
}

In alternative, is it possible to shorten the TextSpanners' X-extent
by the appropriate amount?

Best wishes.

Re: Baseline align in TextSpanner

[Trevor Bača]

Hi Davide,

Avoid the the LilyPond \tempo command entirely: then use markup (in text
spanner bound-details) for everything. Alignment (baseline and otherwise)
can then be controlled with text spanner bound-details.

If you need an empty region of of whitespace between two elements in your
(possibly enchained) text spanners, play with the dash fraction / dash
period of the text spanner to make the dashes disappear, leaving only your
markup visible.

Trevor.

Re: Baseline align in TextSpanner

[Davide Liessi]

Dear Kieren,

your solution works well to keep all TextSpanners baseline-aligned,
but it still does not solve my real problem, which indeed was not
apparent in my first message.
I'm trying to make TextSpanners and tempo markings look the same,
including being aligned at the same baseline.
The reason is to follow the recommendations of Gould for tempo
alteration markings (example at page 184).

A slightly more realistic example follows: I would like to align
\tempo markings and TextSpanners to the same baseline.
As you can see using your trick on both does achieve the desired result.
I renamed the \test function to a more specific \baseline-align.
I'm cc-ing also Harm / Thomas Morley because I'm using his code, so he
may have some insights or suggestions.

Thanks for your help so far.
Best wishes!
Davide

Re: textSpanner at arbitrary positions independent of music

[Ryan Michael]

THank you Pierre,
exactly what i was looking for. However, how can i turn off the left
textSpan property if i want to span four bars which is broken over two
systems, and i don't wish to repeat the "molto rit" for the left attribute
of the span in the second system?

textSpanner at arbitrary positions independent of music

[Ryan Michael]

Hi all

So i have a scenario where I want a textSpanner to follow a heading i have
over the treble clef of a system where there is only action in the left
hand (Bass clef). e.g.

%
\version "2.18.2"
up = \new Staff = "up" {
r1/^\markup{\huge "molto rit."}  r1\startTextSpanner r1 r1\stopTextSpanner
}

down = \new Staff = "down" {
c,,4 c4 c4 c4 c4 c4 c4 c4 c4 c4 c4 c4 c4 c4 c4 c4
}
{
  \new PianoStaff <<
 \up
   \down
  >>
}


my issues is that i want the spanner to really start immediately after the
markup. do i have to make some fake notes in the right hand to anchor the
spanner or can i just move it around by other means?

best,
ryan.

Re: Baseline align in TextSpanner

[Kieren MacMillan]

Hi Davide,

> I want to align TextSpanner texts to baseline.

This works for me:

{
 \override TextSpanner.bound-details.left.text = \markup { \combine 
\transparent "Tj" \test "a" }
 b2\startTextSpan b2\stopTextSpan
 \override TextSpanner.bound-details.left.text = \markup { \combine 
\transparent "Tj" \test "p" }
 b2\startTextSpan b2\stopTextSpan
}

Of course, I prefer to bury the \combine inside any custom markup functions, so 
that I don’t have to remember to add it every time.

Hope that helps!
Kieren.

Baseline align in TextSpanner

[Davide Liessi]

Hi all.
I want to align TextSpanner texts to baseline.
I'm trying to use the code provided by Thomas Morley / Harm in
http://lists.gnu.org/archive/html/lilypond-user/2016-10/msg00365.html
which works very well e.g. with \tempo, but applying \test to
TextSpanner.bound-details.left.text has no effect.
I also tried replacing ly:line-spanner::print in TextSpanner.stencil
with a new function but I couldn't make it work.
An example follows, including Harm's code.
Is there a way to adapt it to my case?
Best wishes.
Davide

\version "2.19.82"

#(define (lists-map function ls)
   "Apply @var{function} to @var{ls} and all of it sublists.
First it recurses over the children, then the function is applied to
@var{ls}."
   (if (list? ls)
   (set! ls (map (lambda (y) (lists-map function y)) ls))
   ls)
   (function ls))

#(define test-proc
   (lambda (e)
 (if (and (list? e) (member 'glyph-string e))
 (begin
  (for-each
   (lambda (x)
 (begin
  (set-car! (cadr x) 0)
  x))
   (cadr (last e)))
  e)
 e)))

  )))

  \override TextSpanner.bound-details.left.text = \markup { \test "p" }

Yes you may be right. There is also this:
http://lilypond.org/doc/v2.19/Documentation/snippets-big-page.html#pitches-modifying-the-ottava-spanner-slope

Though I don't know why in the case of octava-bracket and not for the
TextSpanner, there is a need to override Staff.OttavaBracket.stencil =
#ly:line-spanner::print ?

I agree, I learnt more about bound-details in this forum. The internal
references page is maybe misleading because
(http://lilypond.org/doc/v2.19/Documentation/internals-big-page#textspanner)
will show all the bound-details that are currently used, not all which are
available. 

Many properties can be changed, Y, padding, text, attach-dir,
stencil-align-dir-Y, sencil-offset, etc... left, left-broken, right, etc.
and I also don't know where all of those are listed in the documentation!

That's exactly it. Thanks!

Would be useful as a snippet perhaps... this totally eluded me in the manual. I 
tried to find info about bound-details but missed it somehow.

Hi,

I think you'll have to play with "right-broken" and "left-broken".

Maybe this would help:

\version "2.19.81"

\new Staff \relative c'' {
  
  \override TextSpanner.bound-details.left.text = 
\markup { \small \bold Start }

  \override TextSpanner.bound-details.right.text = 
\markup { \small \bold STOP! }
  \override TextSpanner.bound-details.left-broken.text = ##f
  \override TextSpanner.bound-details.right-broken.text = ##f
  
  c\startTextSpan d e f 
  \break 
  g a b c 
  d1\stopTextSpan
  
}
