Re: Trying to do a template

[Mats Bengtsson]

I guess that you don't want any new type of contexts, you just want
to redefine the existing ChordNames context type. Then, simply do

\layout {
       \context
       {
               \ChordNames
               \override BarLine #'bar-size = #4
               voltaOnThisStaff = ##t
               \consists Bar_engraver
               \consists "Volta_engraver"
               \consists "Percent_repeat_engraver"
       }
}


\chordmode{ \repeat volta 2  {
\partial 8 s8 | f2:maj f:7 \repeat "percent" 2 {bes1:7}
c:maj c:maj c:maj c:maj c:maj c:maj c:maj
} \alternative {
es e }
}


If you want to pursue your idea to define a new context type and
include it in the context hierarchy, then you would need to do
something like the following. Note that you also have to explicitly
instantiate that context in the score:

\layout {
       \context
       {
               \ChordNames
               \name MyChordNames
               \override BarLine #'bar-size = #4
               voltaOnThisStaff = ##t
               \consists Bar_engraver
               \consists "Volta_engraver"
               \consists "Percent_repeat_engraver"
               \alias ChordNames
       }
       \context
       {
               \Score
               \accepts "MyChordNames"
       }

}


\score{
 \new MyChordNames \chordmode{ \repeat volta 2  {
\partial 8 s8 | f2:maj f:7 \repeat "percent" 2 {bes1:7}
c:maj c:maj c:maj c:maj c:maj c:maj c:maj
} \alternative {
es e }
}
}


One of the best ways to learn these things is actually to look at the
definitions of the default context types, see the file ly/engraver-init.ly.
