When I needed SVG in the past, I found it straightforward to generate it 
from Frescobaldi (http://frescobaldi.org ).

In the Lilypond menu, use "Engrave (Custom)" and choose svg as backend.

If your problem is one of wrong command line arguments, then this approach
might work around it.

Best regards,
Stefaan.

Pieter,

The font files aren't in the regular system font folder (you probably
already figured that out). Thay should be found in a folder like:

C:\Program Files\LilyPond\usr\share\lilypond\current\fonts\otf

The font files are actually called "emmentaler-XX.otf". Just copy all of
them (including the Century Schoolbook ones) to the regular system font
folder (C:\Windows\Fonts) and everything should work in Inkscape. On
Windows, this would be the easiest thing for now.

To create SVG output scores, you need to add the lilypond.exe directory
(C:\Program Files\LilyPond\usr\bin) to the PATH environment variable, but
then you should be able to follow any of the regular command line
instructions in the online manual, like:

lilypond -dbackend=svg test.ly

Regards,
Abraham

.ly to .svg - can't manage to get anything working

[Pieter-Jan Van Damme]

Hello guys,

I've been looking for a method to get Lilypond to output to .svg but none
of the methods described online worked for me (I'm using Windows 7).

I tried:

1) using the command line... well, the documentation has left me even more
confused than before I tried it. That may be because I am not overly
familiar with the command line. And I'm suspecting the documentation is
Linux-oriented.

2) when importing a .pdf into Inkscape the note heads and clefs fail to
materialize. Somewhere online it was said I should either uninstall some
Windows updates (https://plus.google.com/+inkscape/posts/RV4qMPKFXkn -
didn't work) or install a font (didn't find the ones referenced; either
Feta ).

Would you guys have any suggestions for a novice like myself?

I think the most complicated part is addressing multiple voices in one
Staff. But propably there are more things to modify to make it more
intuitive. I will see, what I can do during the next two weeks.

Basically, yes.

That too.  Most uses of format before redefinition will continue to work
just fine as they are bound to the variable in the underlying GUILE
module.

ah - this is also Mark's suggestion. So a LilyPond assignment like that
is defining a scheme variable of the given name to be the scheme
structure that right hand side parses to. I get it (?). 
(I wonder, does that mean that all sorts of standard scheme variable
names such as "format" need to be avoided as names for LilyPond
assignments? Or is some scoping stuff in play here ...)

Thanks to both of you for speedy answers, sorry to ask what may seem so

You can write 1/2 instead of (/ 1 2) here.  In 2.19.0, you can actually
write
#(define denemo-transpose #{ cis #})
but I am afraid that this interpretation is not available in 2.18.0

You could try

denemo-transpose = cis'

Richard,

I'm having trouble visualizing what you're trying to
accomplish, couldn't you just do this?

**

myPitch = cis'

myfunc =
#(define-music-function
   (parser location arg)
   (ly:music?)
   #{ \transpose c' #myPitch #arg #})

{
  c' d' e'
  \myfunc { c' d' e' }
}

**

Otherwise, if for some reason you really need to convert
a string to a pitch object, here's one way to do it:

**

stringToPitch =
#(define-scheme-function
   (parser location str)
   (string?)
   (let* ((clone (ly:parser-clone parser '() location))
  (expr (ly:parse-string-expression clone str)))
   (ly:make-pitch (ly:pitch-octave expr)
  (ly:pitch-notename expr)
  (ly:pitch-alteration expr

myPitch = \stringToPitch #"cis'"

myfunc =
#(define-music-function
   (parser location arg)
   (ly:music?)
   #{ \transpose c' #myPitch #arg #})

{
  c' d' e'
  \myfunc { c' d' e' }
}

**

Hope this helps,
Mark

Creating an ly:pitch? value

[Richard Shann]

In music which has a commentary the commentary often refers to excerpts
from the main music. When the main music is transposed it is sometimes
desirable that the music excerpts in the commentary should have the same
transposition.
To save editing these separately I would like to create a music function
which would be invoked before both the music and any excerpts and would
apply a given transposition.

I have got as far as this, for transposing up a semitone as in
\transpose c cis

\version "2.18.0"

#(define denemo-transpose (ly:make-pitch 0 0 (/ 1 2)))
myfunc = #(define-music-function
 (parser location arg)
 (ly:music?)
 #{
\transpose c' #denemo-transpose #arg
 #})


{c' d' e'
\myfunc 
{c' d' e'}}

As you can see I have defined a global variable denemo-transpose to be
the pitch that c' should be transposed to.
My problem is that the syntax for ly:make-pitch is difficult to
generate, but I can't seem to find anything to convert a string like
"cis'" to an ly:pitch? datum.
As you may guess, the code is intended to be generated programmatically
(from Denemo), which may limit the available solutions.

Any ideas?

absolute baseline-skip

[Karol Majewski]

Hi,

I'm trying to redefine abs-fontsize from define-markup-commands.scm, so that 
baseline-skip is also absolute. Current behavior is that with abs-fontsize, 
baseline-skip scales to global-staff-size, which I don't like. I know that 
there was attempt made by Nicolas Sceaux 
(http://lilypond.1069038.n5.nabble.com/Markup-in-absolute-font-size-td34087.html),
 but no solution there. Here's original code:


#(define-markup-command (abs-fontsize layout props size arg)
  (number? markup?)
  #:category font
  (let* ((ref-size (ly:output-def-lookup layout 'text-font-size 12))
 (text-props (list (ly:output-def-lookup layout 'text-font-defaults)))
 (ref-word-space (chain-assoc-get 'word-space text-props 0.6))
 (ref-baseline (chain-assoc-get 'baseline-skip text-props 3))
 (magnification (/ size ref-size)))
(interpret-markup
 layout
 (cons
  `((baseline-skip . ,(* magnification ref-baseline))
(word-space . ,(* magnification ref-word-space))
(font-size . ,(magnification->font-size magnification)))
  props)
 arg)))


If you have any ideas, please share! Perhaps something like abs-baseline-skip 
is needed?

Re: Template: String Quartet (score-only), first draft

[MarcM]

I found this thread via google and it dates from few years back.

I include the sample at the end of this mail.

You can compare it with the one here:
http://www.lilypond.org/doc/v2.18/Documentation/learning/string-quartet


The documentation shows a sample for string quartet parts  which requires to
uncomment lines.
http://www.lilypond.org/doc/v2.18/Documentation/learning/string-quartet-parts

Would anyone already have another template for quartet part that does not 
 require to uncomment lines of code like the one in the documentation? 
 When i am working on each part i want to print the score of the part then 
 if  i need to print the set of parts i just want to open the 
 quartet_AllParts.ly, typeset and print without having to uncomment lines 
of code everytime.

That's pretty small. I don't remember being that small.

Well, check your PDF file in a PDF viewer.  Most importantly, check the
paper format.  If it is indeed letter and properly positioned, the
problem is when going from PDF to your printer.

I'll try to find a way through the options. I think that when there is 
an automatic way to generate the documentation this will encourage 
authors to do it right in the first place. Just an example: The 
"description" header field will be used in the documentation. And when 
one sees this in the HTML docs one will voluntarily take care of having 
a good description.


But I'll try to keep the complexity as low as possible.
I think the decision to have a single directory for all include files 
was a good one in that respect.

The script will have two stages: parsing the content of the library and
generating documentation from the resulting internal representation. I
think generating complete HTML pages isn't more complicated than
generating Markdown, but the results are better to use: We have more
control over the layout and formatting options than on a Github Wiki,
_and_  we have a self-contained HTML site that can also be deployed
locally.


Yep.



This might be a good opportunity to get my feet wet with PyQt, i.e. not to
write a _script_ but an application. Initially this wouldn't do much more
than a mere script, but with more convenient interactivity. Later it could
add an interface to _edit_ the metadata (e.g. selecting from existing tags,
batch renaming of tags etc.) and also the documentation strings themselves.
And it can even incorporate a convenient documentation browser.

I think we should target the documentation output to be a self-contained
HTML site in the repository itself (in a /doc directory) and only them
consider making it available online too.

At least with the HTML part of such a documentation I'd be glad for
assistance (if I really get this started at all). Not that I'm unable to do
that part but others can do that better, and it's a convenient split-point
to share work.

I am wondering if this is an expected behavior or something is wrong my
computer and/or printer (HP Officejet Pro).

My music is set with \paper {   #(set-paper-size "letter")}

I print on a printer on which the default paper is "letter"

When i print with the default settings the margins are truncated and the
only half of the title of the piece is printed. To print correctly i have 
to

select the option to "print the entire image" which scale the page down to
91%. Is that normal?



I would guess your printer has a top margin that is larger than LilyPond 
sets by default, and larger than most printers.  Have you tried setting a 
larger top-margin?

1) This String quartet example is much nicer than the one in the current
documentation.
http://www.lilypond.org/doc/v2.18/Documentation/learning/string-quartet

Can we include it in the documentation?


2) Would anyone already have another template for quartet part that does 
not

require to uncomment lines of code like the one in the documentation?
When i am working on each part i want to print the score of the part then 
if

i need to print the set of parts i just want to open the
quartet_AllParts.ly, typeset and print without having to uncomment lines 
of

code everytime.



Sorry, Marc, I don't follow you.  Which template?  Which commented lines?

Maybe I am going mad but when I am trying to look at the thread to this
to find out what example ' ... is much nicer ...' I am being taken back
to conversations from 2008!

Would you care to elaborate a bit more Marc (in case I am wrong) as I
cannot find anything else pertaining to this email.

Re: shiftOn shifts to the left

[Alberto Simões]

Hello, Abraham


I think part of the confusion is the musical context for what you are trying
to do. Is this something of your creation or are you transcribing an
existing score that we could look at to get a better understanding?


Yes, I was trying to mimic an existing score. That note is from a third 
voice in the staff below. I know I can change staff, but I though it 
would be easier adding it artificially.



2. Make the "e2." the only "\voiceTwo" notehead at that point in question
and put a spacer where the second voice's "e" would be.

\score {
   \new Staff \relative c'' <<
 {
   \time 3/4
   a4 b c
 }\\<<
   { s4 g a ~ | 2. }
   \new Voice { \voiceTwo e2. | s2. }
 >>
   >>
   \layout{}
}




Yes, this would be an option, but then I miss a note :-)

Oh well, thank you for your help. I will keep the note at the left :)

Best,
Alberto

Re: [openlilylib] Discuss restructuring

[Janek Warchoł]

Hi folks,

as you can see, i'm falling behind with lilypond stuff, but i wanted
to let you know that i've skimmed through this discussion and it LGTM.
The only comment i have is: try to make things as simple as possible
(but not simpler, of course) - i wouldn't like openlilylib getting a
"java-smell" from trying to be overly generic and all-encompassing.
Please continue with my blessing ;-)

best,
Janek

Indeed, it seems that the approach used by Jay is the correct one
(i.e. using an engraver).

Would you like to help with making a patch and shepherding it through
the review process? As you can see, i don't have enough time for
lilypond work, so cannot do it myself.  Of course, i know that this is
an involved process, so i'm willing to offer you assistance (short
Skype call every other day).  It seems to me that Jay's code is of
good quality, so it shouldn't require a lot of work.

best,
Janek

It's been done before (i have quite some music on github) but i think
it's worth a ponding anyway.

Absolutely, but right now i'm not sure if there's not enough people
that could gather at one place at the same time.

Alberto,

I think part of the confusion is the musical context for what you are trying
to do. Is this something of your creation or are you transcribing an
existing score that we could look at to get a better understanding?

Based on this discussion, it seems like you have two options:

1. Apply the "\voiceThree" to the "e2." which shifts the notehead to the
right, but puts the stem up, 

\score {
  \new Staff \relative c'' <<
{
  \time 3/4
  a4 b c
}\\<<
  { e,4 g a ~ | 2. } 
  \new Voice { \voiceThree e2. | s2. } 
>>
  >>
  \layout{}
}

 

or

2. Make the "e2." the only "\voiceTwo" notehead at that point in question
and put a spacer where the second voice's "e" would be.

\score {
  \new Staff \relative c'' <<
{
  \time 3/4
  a4 b c
}\\<<
  { s4 g a ~ | 2. } 
  \new Voice { \voiceTwo e2. | s2. } 
>>
  >>
  \layout{}
}

 

Personally, i like the second option better. Either way, proper usage of the
\voiceX commands  and "\\" syntax should provide the right solution.

Hope that helps,
Abraham

P.S. Changing the stem direction changes the note's NoteColumn for collision
identification, it doesn't _necessarily_ change the voice.
