Re: Barline at beginning of lines of music.

[Richard Shann]

Well, I'm not sure I follow the distinction between defined bar-types
and not, this code

\version "2.18.0"
\defineBarLine ":" #'(":" ":" ":")
\defineBarLine "|" #'(":" ":" ":")
\score { 
 
    \new PianoStaff << 
        \new Staff = "RH"  << 
         \new Voice  { 
         c''  c'' c'' c'' c'' c''  }               
        >>
        \new Staff = "LH"  << 
         \new Voice  { 
          c''  c'' c'' c'' c'' c''  } 
        >>
    >>
}

gives no warning but prints the double dots above instead of below the
top staff.
But perhaps that is a separate bug.
In any case, I seem to have a workable method for creating the bar types
needed for chord charts. Attached is an example of the sort of output.
The code to generate this is now in Denemo's git and will be in the
1.1.8 release.

Thanks to all who replied,

Richard
