Re: get current bar number

[Jan-Peter Voigt]

Hi Kevin,

yes, you need to get a context object. If you want to use it inside some 
music expression \applyContext is the key:

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
doSomething =
\applyContext #(lambda (context)
                 (display
                  (ly:context-property context 'currentBarNumber)
                  ))

{ c''4 \doSomething d'' }
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

If you are going to write an engraver you can find some informations in 
the archive.
