I searched the archives in order to find a way to insert bar lines at
the left side of staves and found two interesting threads. In the
newer thread you mentioned that it was not possible (because of
something hardcoded) and there was no reply to your article at the
lilypond-devel archive.
However, I found a thread from last year in which you posted an “ugly
solution” which I tried (2.10.25).
The code works, but unfortunately I can neither use my sectionLetter
nor “\bar "||"” insertions.
Is there now a way to have those bar lines in a “non ugly” way, or to
make your code work with my sectionLetter and “\bar "||"”?
TIA
