Re: staffSize music function unreliable at LP v2.19.16

[Pierre Perol-Schneider]

No problem on my side (see attached).

OS : Ubuntu 14.10

Frescobaldi 2.13

LP 2.19.16

Here's a compilable code:

\version "2.19.16"

staffSize = #(define-music-function (parser location new-size)
               (number?)
                #{
                  \set fontSize = #new-size
                  \override StaffSymbol.staff-space = #(magstep new-size)
                  \override StaffSymbol.thickness = #(magstep new-size)
                #})

Ab = \relative c' { f4 g a b  }

\score {
  \new Staff  \with { \staffSize #2 } { \Ab }
  \layout { }
}

Cheers,

Pierre

produces at LP v2.19.15:

but at LP v2.19.16 produces:

Besides being wrong (see, e.g., "Behind Bars" by Elaine Gould, p.13), this causes many scores to require an additional page.

Applying convert-ly to the above snippet changes only the \version number.

I tried all values for new-size between -8 and +8; the only ones that failed were -4 and 2.

(The staffSize music-function was kindly contributed by Eluze in 2013 on this list to overcome limitations of layout-set-staff-size.)

I have been able to reproduce the problem on Windows 7 with Frescobaldi 2.17.2. 

Additionally I found that sizes of 2.1, 1.4, 1.1, 0.7, 0.5, -0.2, -0.3, -0.6, -1.3, -1.4, -2.1 also created the down stem on the F. (I only tested 2.1 to -2.1).
