Can I edit the properties of System Spacers in LilyPond and double it on the other side of the page?

Question

I can't find any information about system spacers more than:

\paper {
   system-separator-markup = \slashSeparator
}

I find the defaults too small, and I would like to put a second separator aligned to the right (so both sides have one)

Is this possible?

Answer 1

Okay, what I did was to make a copy of the titling-init.ly in another folder (in my documents), edit some things (please change the name of the variable) and include it in my files with \include.

However, It's actually more useful to just copy the slashSeparator variable into a file instead of making a copy of the entire titling-init.ly and play around with the numbers and else so you can see what they mean.

What worked for me was doubling some of the numbers and adding some extra stuff, so this is my result:

NEW-NAME-OF-YOUR-OWN-VARIABLE = \markup {
  \left-column {
  \vcenter \combine
  \beam #4.0 #0.5 #0.96
  \raise #1.4 \beam #4.0 #0.5 #0.96
  }
  \hspace #100
  \right-column {
  \vcenter \combine
  \beam #4.0 #0.5 #0.96
  \raise #1.4 \beam #4.0 #0.5 #0.96
  }
}

You can just copy that into your working file or save it in another file and include it. And then add it to:

\paper {
   system-separator-markup = \NEW-NAME-OF-YOUR-OWN-VARIABLE
}
