Re: Snippet for aligning markup inside another markup

[Michael Käppler]

Hi Aaron and Kieren,
very nice!
(I really should have read how the markup commands make use of 
ly:stencil-aligned-to...)
Here my variant of the code with tweakable alignment. Personally I 
prefer the "scheme only-style" but
I agree that the mixed style Aaron used would be shorter.

%%%%
\version "2.19.80"

#(define-markup-command (aligned-overlay layout props xdir ydir args)
   (number? number? markup-list?)
   (let* ((stencils (interpret-markup-list layout props args))
          (align (lambda (stencil)
                   (ly:stencil-aligned-to
                              (ly:stencil-aligned-to stencil X xdir)
                              Y ydir)))
          (stencils-aligned-merged (apply ly:stencil-add (map align 
stencils))))
     (ly:stencil-aligned-to (ly:stencil-aligned-to 
stencils-aligned-merged X LEFT)
       Y DOWN)))

boxone = \markup \with-color #yellow \filled-box #'(0 . 10) #'(0 . 10) #0
boxtwo = \markup \with-color #green \filled-box #'(3 . 9) #'(5 . 11) #0
boxthree = \markup \with-color #red \filled-box #'(2 . 5) #'(3 . 6) #0

\markup \column {
  "Without alignment"
  \overlay { \boxone \boxtwo \boxthree }
  \line {
      \column {
        "Everything centered "
        \aligned-overlay #CENTER #CENTER { \boxone \boxtwo \boxthree }
      }
      \column {
        "Everything aligned to bottom-left "
        \aligned-overlay #LEFT #DOWN { \boxone \boxtwo \boxthree }
      }
      \column {
        "Different alignments "
        \aligned-overlay #CENTER #UP {
          \boxone
          \aligned-overlay #LEFT #CENTER { \boxtwo \boxthree }
        }
      }
      \column {
        "Values in-between"
        \aligned-overlay #-0.8 #-0.5 {
          \boxone
          \aligned-overlay #0.5 #-0.2 { \boxtwo \boxthree }
        }
      }
  }
}

Cheers,
Michael
