Thank you, Valentin, 

Specially for the examples, I will study, experiment with them and see how I 
can learn how to solve my issues this way.

Don’t copy the contents of the file. Just put the EPS file next to your 
LilyPond file and write


\markup \epsfile #Y #10 "name-of-file.eps"

in your LilyPond code.

Re: Organising files/variables/ in lilypond

[Valentin Petzel]

Hello Eef,

if I understand you correctly you essentially want to put the content of a 
Lilypond file into a variable and evaluate that. This is not possible with 
Lilypond as such, but instead you can avoid Lilypond syntax and directly use 
the scheme hooks.

Instead of doing

all = ...

you can have a scheme function do

(set! all ...)

(but for this to work you need to have the binding "all" existing before by 
doing #(define all #f) (or any other value).

Instead of simply creating a \score ... and let the parser delegate this to 
the correct hook you can pass scores directly via scheme by doing

(add-score #{ \score { ... } #})

Generally there are many ways to do things, and we’d need to know more about 
your specific situation to be able to elaborate a good solution.

Recently I did a mass for which I created a small framework which allows me to 
first register parts and such by doing

\registerPart partname
\partSetTitle partname "Title"

\partSetStaff partname staffname { music }
...

and then when needed do

\partPrint name layoutfunction

to create a specific score or

\printParts layoutfunction

to print all scores.

layoutfunction is then a function taking partname and creating the desired 
score.

I’d then have a folder "layouts" specifying layout functions, a folder 
"styles" specifying stylesheets, and a folder of files registering scores, and 
one or multiple masters reading these files and printing scores with one or 
multiple layout functions.

I’ve included the core library and an example layout function. Maybe this 
approach could be useful for you (I’ve also sent this to the list not too long 
ago).

Cheers,
Valentin

If I understand your request correctly, you can convert the SVG file to 
EPS, for example using librsvg with


rsvg-convert --format=eps file.svg > file.eps

then include it with \epsfile.

Of course, you will need to install librsvg.

There are also countless websites out there where you can do the SVG -> EPS 
conversion step online.

define-markup-command

[Ken Ledeen]

Hi All,

Thanks to Jean Abou Samra I can now create \markup that goes to a place in
a youtube video.

These are of the form:

fis4^\markup \with-url#"https://youtu.be...?t=SEC; {ref} where "SEC" is
replaced with the number of seconds in from the start.

I would like to create a function to simplify things so instead of having
the entire URL repeated everywhere, would have something that looks like

fis4^\mymk "215".

So far, I remain entirely confused about creating a new markup command.  I
won't bother describing my many failed attempts.  I am clearly missing some
basic concepts. I have no problem creating scheme functions to do various
manipulations, but extending the markup function has eluded me.

Any guidance would be most appreciated!

Organising files/variables/ in lilypond

[Eef Weenink]

I have this project: I make arrangements of figured bass pieces. (Generalbass 
Wolf). In total 100 pieces.
Uptill now I organised it this way:
- 1 file with all pieces in it (I did about 10, 90 to go).
The file starts with an include of a startup.ily, with some settings for the 
whole book
then the first piece.
I include a file (arrangeit.ily) to change the music into several voices, 
etcetera using arranger.ly.
I add some lines to change 1-2 voices a bit using also 
arranger.ly
then I include a file (Generalbassmakescore.ily with the settings to create the 
score.
Second piece (with the same variablenames!)
and repeat the includes like mentioned above.
etcetera.

It works, looks well. At the end I have 1 file with alle the pieces and 3-4 
files to do small jobs, It is not fast.

But somehow I have the idea this could be easier/better. But how?
- One idea would be to put all pieces in separate files and include this in one 
file with all jobs: arranging, extra changes, create voice/score. But then I 
will have 101 files

Most easy would be to create a file with procedures I need, include the file 
and call the procedures when needed. . But how? Lilypond does not have 
procedures (as far I know?).
Using functions gives lots of errors.
I tried it with variables, but no luck either.

I try to put these lines in a variable/function/procedures (as an example):
What to do, to make lilypond use the lines between {} simply as a replacement 
of the variable?

arrangeit = {
%- verwerking---
all = #'(pright pleft  soprano alto tenor bass viola contrabas soprano)
#(init all)

 #(begin
   ;;pianopartij
  (rm 'pright '(1-4)   (rel 1 'melody) )
  (rm 'pleft '(1-4)   (rel  'bassline) )

;; koorpartijen
;; sopraan
  (rm 'soprano '(1-4) (note 1 (rel   'melody) ))
;;alt
  (rm 'alto '(1-4)   (note 2  (rel  1 'melody)) )

signs) and not signed notes it's quite not hearable; I found in docs
instructions about how to modify the output level of each midi instrument ,
and the same about output level of applied signs; every time docs refers to
a scm/midi.scm file, for default settings, but I can't understand its
values; I need to know what defaults settings are, for trying to manage
them. Any help about is very appreciated

regards

movement in markups like TeX's `em` and `ex` units

[Werner LEMBERG]

Consider the following snippet:

```
Emaj = \markup { E \raise #1 maj }

\markup \Emaj

\markup \fontsize #10 \Emaj
```

As can be seen, `\raise #1` is not the right value in the second case.
What I would like to have instead is an equivalent to TeX's relative
units `em` and `ex`, being multiples of the width of glyph 'm' and the
height of glyph 'x', respectively (HTML/CSS has that too, BTW).

How can I do that in LilyPond?  I could imagine code like

```
Emaj = \markup { E \raise #(* 1 ex) maj }
```

In other words, font-related command like `\fontsize` could set up
markup-wide entities `ex` and `em` that can be used for offsets
depending the current (scaled) font dimensions.

Or maybe

```
Emaj = \markup { E \raise #(ex 1) maj }
```

where function `ex` examines the current font and gets the 'ex' value?
Ditto for a function `em`.

Re: Markup in the middle of a spanner

[Andrew Bernard]

Others will shortly come in with a formal Scheme solution but I just use 
markup text with a whiteout background and manually offset it to be in 
the middle of the spanner. No good when things shift, but does the job.


I thought there used to be a technique for this in the Lilypond Snippet 
Repository but I can't find it just now.

Markup in the middle of a spanner

[Rip _Mus]

Hello,
do you know any technique to place a markup right in the middle (X axis) of
a DurationLine Grob? (or also a textspanner).

Thank you
