Re: centering text on a measure

The function in the attached file lets you specify multiple markers for a grob, so it can serve in multiple pairings (there can only be two which use the same tag).  The example in the file should show how this works.

Hope this can be useful in some way --

Hi David,

setting 'markers to a list is a great idea and I've never got warnings or wrong output.

Your definition should be putted in the LSR as soon as it's updated to 2.14.

One tiny thing I noticed testing the code: It's possible to call 'markers from different voices and staffs, even if I use: \once \override Voice ...

One of my testings (without the definitions):

redln = \markup \with-color #red \draw-line #'(0 . 6)
blueln = \markup \with-color #blue \draw-line #'(0 . 15)

>\relative c' {
        \once \override Stem #'color = #red
        \once \override Stem #'markers = #'("x")
        \once \override Voice.TextScript #'extra-offset = #(center-between "x" -6)
        c'4-\redln  c c c
        d d
        \once \override Voice.TextScript #'extra-offset = #(center-between "y" -15)
        d-\blueln
        \once \override Stem #'color = #blue
        \once \override Stem #'markers = #'("y")
        d
}

two =
\relative c {
        c'4
        \once \override Stem #'color = #red
        \once \override Stem #'markers = #'("x")
        c c c
        d d d d
}

three =
\relative c' {
        c'4 c c c
        d d d d
}

four =
\relative c {
        c'4 c c c
        \once \override Stem #'color = #blue
        \once \override Stem #'markers = #'("y")
        d d d d
}
\score {
\new StaffGroup <<
    \new Staff <<
      \new Voice { \voiceOne \one }
      \new Voice { \voiceTwo \two }
    >>
    \new Staff <<
      \new Voice { \voiceOne \three }
      \new Voice { \voiceTwo \four }
    >>
>>
}

This might be a feature. Or is it a problem? I'm not sure.

Best,
