Installation problem

[bluefander]

Hello,

I have this lilypond code:

\version "2.26.0"
\language "deutsch"
\include "/home/stefan/lilypond_extension/esmuflily-main/ly/esmufl.ily"
ekmFont = "Bravura"

\relative c' {

a4 h c d

}

I moved ekmd.scm and ekmd-template.scm to /usr/share/lilypond/2.26.0/scm/lily/
When I run the code above I am getting this error and I have no idea how to fix this.

I fixed the error in "ekmd.scm". Please reinstall it.

But most importantly, ekmFont must be placed before the \include, else it is ignored (also ekmUse before including "cosmufl.ily").

I recommend to install a precast metadata cache file for the desired font, if available, like "ekmd-bravura.scm" for Bravura. It provides much better font-specific support than the universal "ekmd-template.scm".

Thanks for your fix!

I am still running into problems though.
I copied your updated ekmd.scm as well as ekmd-bravura.scm and ekmd-ekmelos.scm to /usr/share/lilypond/2.26.0./scm/lily

If I know run this code which is more or less the code from page 51 of the esmuflily.pdf I am still facing error messages:

\version "2.26.0"
\language "deutsch"

ekmFont = "Bravura"
\include "/home/stefan/lilypond_extension/esmuflily-main/ly/esmufl.ily"

\relative c'' {
\ekmSmuflOn #'rest
\compressMMRests {
\time 2/4
R2 R1 R\breve R\longa R\maxima
}

I can't find a problem with the code.

Maybe all required files - esmufl.ily, ekmd.scm, and ekmd-bravura.scm - should be placed in the same folder outside of Lilypond installation folders. I always do this to be independent of the currently used Lilyüond version.

[bluefander]

Hmm... I might be doing something wrong.
So I deleted all the files you mentioned which I put in the Lilypond installation folders before.
They are located in this directory: /home/stefan/lilypond_extension/esmuflily-main/

In the documentation I read:
Install from folder ly the following files:
• esmufl.ily
• ekmd.scm
• ekmd-template.scm

What does install actually mean?

[tr-igem]

Exactly what you did, to put the files in a folder that is in Lilypond's search path.

Sorry for all the annoyances...
My LLM thinks there is a problem with a missing metatable initialization.
I tried it like this:

\version "2.26.0"
\language "deutsch"

ekmMetadata = "/home/stefan/lilypond_extension/bravura-bravura-1.380/redist/bravura_metadata.json"

\include "/home/stefan/lilypond_extension/esmuflily-main/ly/esmufl.ily"

\relative c'' {
\ekmSmuflOn #'rest
\compressMMRests {
\time 2/4
R2 R1 R\breve R\longa R\maxima
}

}

I tried this metadata file:
https://github.com/steinbergmedia/bravura/tree/master/redist

Still getting the same error.
