Re: use guile to set specific extra-offset values if stem direction is up or down

[padovani]

Hi again,

so.. as the flags are now separate objects (2.15.38), I'm having 
problems to move them to the same place that I am moving the stems... if 
I just reproduce the lambda function I am using with Stems with flags, 
it does not work...

\once \override Stem #'extra-offset =
        #(lambda (grob)
         (if (eq? (ly:grob-property grob 'direction) UP)
          '(-0.02 . -0.25) '(0.02 . 0.25)))

%this fails
\once \override Flag #'extra-offset =
        #(lambda (grob)
         (if (eq? (ly:grob-property grob 'direction) UP)
          '(-0.02 . -0.25) '(0.02 . 0.25)))

So, is there a way to know the Flag direction? Or maybe a wat to access 
the Stem's grob from the Flag one (so that I can point the function to 
the Stem properties?).

Thank you again,

José
