Re: SVG output - Group multiple grobs together

[James Opstad]

Thanks. I will work through the example. It seems it isn't possible to embed 
more than one item within a group and one group per grob is the only approach 
for the time being. If this is the case then why use groups rather than adding 
the attributes to the grob itself?

All grobs have pointers to other single grobs or arrays of other
grobs.  You gain access to these through such functions as
ly:grob-parent, ly:grob-object, ly:grob-array, ly:item-get-column.
The idea of "multiple grobs within the same group e.g. all the grobs
associated with a single note" can prove to be complex since your idea
of a grouping is not necesarily LilyPond's.  You may have to follow
chains of pointers--as I did below to arrive at the Stem grob from
NoteHead: i.e, through NoteColumn, the Y-parent of the NoteHead.

So here is something quickly hacked together from your code example:

\version "2.19.65"

\pointAndClickOff
\relative c' {
  \once \override NoteHead.output-attributes =
  #(lambda (grob)
 (let* ((acc (ly:grob-object grob 'accidental-grob))
(acc-name (if (ly:grob? acc) (grob::name acc) "none"))
; we need a NoteColumn object for access to other grobs
(nc (ly:grob-parent grob Y))
(stem (ly:grob-object nc 'stem))
(stem-name (if (ly:grob? stem) (grob::name stem) "none"))
(pc (ly:item-get-column grob))
(pc-name (if (ly:grob? pc) (grob::name pc) "none"))
(elts (ly:grob-object pc 'elements)))
   (display elts) ; just so you see a grob array
   (list
(cons 'id 'noteC)
(cons 'accidental acc-name)
(cons 'stem stem-name)
(cons 'column pc-name

  c4 d e f |
}

%%%

Here is a link to something you might find useful.  It stores data
about every grob encountered.

Good question.  I think it's because some grobs produce more than one 
glyph, path, or shape in the SVG, so the groups group these together as 
one thing.  Might be interesting to explore feasibility of conditionally 
adding groups only when needed (for grobs with multiple shapes) and 
otherwise adding properties to the (single) SVG shapes themselves.

Hi, I don't think there is currently a way to do that.  You could give 
each grob you want to group together the same id.  Your SVG will not be 
as concise or elegant (one group per grob), but it might be a way to get 
the job done.

Re: SVG output with 2.19.31

Answering my own issue on further investigation, I refer to Noto Sans Bold 
Italic in an override for dynamics. My system lacks the SVG fonts for this 
typeface. Enabling –V and going through the backtrace led to some insight.

But the error message presented that just refers to font #f is not very

Yes, it works correctly in 2.16. It’s clearly a regression. 

 

I’m wondering how the backend can influence the rendering this much. In

graphical primitives.

To be more specific: To be a regression it had to be working before _on 
purpose_. That is someone has to have deliberately make it work earlier. 
If it just worked before it's no regression.

Maybe there's a category of elements that comprises both sounding notes and

used instead of note above?

Also:

path style=... d=... id=bar1
path style=... d=... id=bar2
path style=... d=... id=bar3
etc...

I thought about the svg grouping option, but that would be a more radical
revision than creating smart id's like above. Such id's would IMPLY grouping,
semantically.  The parsers could sort out and group elements much more easily,
it seams, actually adding the svg grouping, post factum, if need be.

Hi, guys:

I don't think I have the font problem (I'm on Ubuntu, and I viewed the attached
svg files in Inkscape with no apparent problems); however, I can't even get past
step 1 — saving as svg. I end up with a ps file, not svg. I do the
following:

lilypond -o outfile.svg -fsvg infile.ly

and that prints:

Processing `infile.ly'
Parsing...

Preprocessing graphical objects...

And the only thing produced is  outfile.svg.ps, and it IS a post-script file,
not an svg.

What am I doing wrong?

 have you tried the backend svg:
 lilypond -dbackend=svg infile.ly

 svg uses for some reason not the format but the backend option.


keep a look to this issue:

please note that lilypond adds the extension automatically so probably you
want to write

lilypond -o outfile -dbackend=svg infile.ly

Re: svg output

[Gerard McConnell]

Thanks very much gents, it is a font problem.   I opened the svg file with
a text editor and replaced Lilypond's Century Schoolbook L with Times New
Roman for all text occurrences, which solved the problem.   I  guess in
order to avoid having to do that I need to make Inkscape see the Century
Schoolbook L font?   How come Lilypond can find the font but Inkscape
cannot?

By the way, I presume I'm top-posting.  I read somewhere that there's
something wrong with doing that, but doesn't it allow whoever is following
the thread to get the new material without having to go through the old
material?
Thanks again,
Gerard

 Does that help at all?

 Should be an easy fix,

Re: svg output

[Gerard McConnell]

Apparently Microsoft has created the problem:

«Known issues with this security update
We are aware of issues related to OpenType Font (OTF) rendering in
applications such as PowerPoint on affected versions of Windows that occur
after this security update is applied. We are currently investigating these
issues and will take appropriate action to address the known issues. »

I'll have a look at the manual and see if I can find out how to use an
alternative font in Lilypond for now.
Thanks again for the help,

the problem isn't solved.  I've placed the .ly and .svg files, and pictures
(screen dumps?) of the .pdf output from Lilypond (which is fine) and the

I have found the combination of Lilypond's .svg output with further editing
in Inkscape to be the perfect solution for my needs.  Thanks very much for
any help with this.

Hmm, when I compile this example, a valid SVG is created.  See the

Are you running a self-compiled LilyPond or one of the binaries from

git tree to a pristine state before compiling?

This is strange. I use a self-compiled LilyPond with the current git status.
I am on branch master, nothing changed ...
After the most recent pull, I am on
SHA1 Id 42840bbfdfe82eddc8e04026865aef278b80fc0a

Apart from that, everything else seems to work properly.

Hi Keith,

Thanks for posting the image.

If question is whether or not this is possible with LilyPond, I would
say Yes!, but I can't really think of any way to easily achieve the
results you want.

You *might* try adding slurs to the melody in the appropriate places,
and then using Inkscape to drag the slurs down to the appropriate
locations.

I'm sorry I can't be of more help; I don't use lyrics with LilyPond
very often, so my knowledge is a bit rusty.

This is a job that non-programmers can do; once a problematic commit is

problematic commit.

 7.6 Finding the cause of a regression

 Please, which job, _what_ can i do?-) What should i do to identify
 problematic commit?

Sorry, I was unclear -- I'm not asking random people to find the
*cause* of a regression.  Just find a regression.

1.  Comparisons: go here, and select the version you want to check:
http://lilypond.org/test/
for example, v2.13.11-1

You'll see the difference in regtests between v2.13.10 and v2.13.11.
For any change, ask yourself if it's a change for the worse or better.
 (or just no real change at all)

2.  Checking all regtests:
http://lilypond.org/doc/v2.13/Documentation/web/development
and find the link for regression tests  (warning: downloads a large
number of images, so be patient)

Each regtest has a short description, then an image.  Does the image
match the description?  If not, send an email to bug-lilypond like

In the ancient-accidental.ly regtest, the accidentals for hufnagel
and vaticana look exactly the same.  Shouldn't they be different?

(this isn't true in 2.13.11, but if they *did* look the same, it would be a bug)

 (Can this regtests checking be automated?.. Yes, i do have
 bash/sed/awk/python and some idea how to use them, it this can help.
 Yes, i'm lazy too, but not so delicious and bad, probably.)

The regtest comparison is automated -- humans only need to check on
average a dozen images, instead of 300 or whatever.

Cheers,
- Graham

Well... i'll try.

Just have subscribed to bug-lilypond.

The problem is... yes, i'm not a programmer, but i'm not a musician,
either :O)

For instance: In the ancient-accidental.ly regtest, the accidentals for
hufnagel and **MENSURAL** look exactly the same.  Shouldn't they be
different? I don't know actually.

Oh well... i will ask (after some read-only grace period) bug-lilypond,

Well, ignore any regtests that you have no clue about.

That said, in our hypothetical bug, it should be pretty clear -- I
don't know anything about ancient accidentals, but since the text
implies that ABC style is different from XYZ style, if I can't see
any visual difference I'll ask if it's a bug.

Re: svg output

[Hugh Myers]

Keeping in mind that I agree with Graham on all points, here is a
recent quote from Wikipedia:

All major modern web browsers except Microsoft Internet Explorer
support and render SVG markup directly.[3] To view SVG files in
Internet Explorer, either users have to download and install a browser
plugin, or the webmaster can include SVG Web, a JavaScript library
currently under development at Google Code[4].

This suggests that 'next year in Jerusalem' is a bit closer than
previously thought.

Ah, okay.  The SVG output has been greatly improved in the past few
months, but there are not any official releases that contain these
improvements yet.

Version 2.13.4 will have these changes, whenever it is released.

In the meantime, you can view examples of the current SVG output here:

Thanks for that suggestion. Do you know where I can get the gnome

However, I think there is a more general issue here about graphical 
notation in scores. I'm using various bits of graphics in this piece

to a bitmap, and also because Inkscape is a good piece of software. If 
fixing the SVG output isn't an option, does anyone have experiences of 
how to do this?


Thanks in advance,

IIRC, it's a compile-time option which by default is off (i.e., you need to 
recompile lily manually).

Again, if your only problem is to adjust offsets etc, then getting the gnome 
back-end to work may be a good solution for this problem too (i.e.: insert 
EPS markups without considering spacing offsets, then move them to the right 
spot using the gnome back-end). A problem here is that EPS images probably 
won't show up in the gnome back-end. IIRC, it's possible to store a bitmap 
preview in an EPS image; in this case it may be possible to hack the gnome 
back-end to extract  display the preview.
