RE: Weird parentheses

Simon,

Perhaps an alternative is under "compound time signatures" at

Weird indeed.

Some of that sounds like using the number command may be the problem, because 
the font doesn’t contain many normal glyphs. Try experimenting with the 
normal-text markup command.

However, still more weird is that I don’t get any of those problems: the markup 
itself looks OK, but there’s some white space instead of the start of the staff 
symbol. This is on Ubuntu 16.04, with Lily 2.19.82.

I’d experiment in this direction with the markup:

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
\version "2.19.82"

\language "english"

#(define-markup-command (timesig-paren layout props opening?) (boolean?)
    (interpret-markup layout props
      (markup #:normal-text
        #:override '(font-size . 6)
        #:scale '(0.5 . 1)
        #:vcenter
        (if opening? "(" ")"))))


#(define ((time-parenthesized-time up down upp1 downp1 upp2 downp2)
grob)
    (grob-interpret-markup grob
      (markup #:override '(baseline-skip . 0) #:number
        (#:line (
            (#:center-column (up down))
            #:timesig-paren #t
            (#:center-column (upp1 downp1))
            #:normal-text #:lower 0.5 "+"
            (#:center-column (upp2 downp2))
            #:timesig-paren #f )))))

\new Staff {
   \override Staff.TimeSignature.stencil = #(time-parenthesized-time "21" "8" 
"12" "8" "9" "8") } %%%%%%%%%%%%%%%%%%%%%

Output attached – I don’t know where that whitespace comes from.

Best, Simon
