Re: Overriding bar-line behaviour

[Matthias Hüsken]

Sorry for the noise on the mailing list - I knew it was some stupid mistake... 
I tried to override the wrong value, it should have been

\override Score.BarLine #'break-glyph-function = #my-bar-line::calc-glyph-name

instead of

\override Staff.BarLine #'glyph-name = #my-bar-line::calc-glyph-name

Corrected file attached. Cheers,

Matthias
