Hi Federico,
for the record, below my own first approach to the problem. Be aware
it's more a sketch of an idea, not ready to commit, although it
compiles.
Much more primitive than Nicolas' code, maybe I'll somewhere find he
time to look into it with more depth (and into all the other points on
my personal todo-list...)
\version "2.19.29"
%% split-stil-list
%% first part contains all stils, which don't exceed `amount' with their
%% accumulated Y-length
%% second part all others.
%% Ofcourse only two sublists are created, which will limit the
%% later defined markup-list-command to two columns
%% If the length of both list don't match, add point-stencils unless they do
#(define (split-stil-list stil-list rl init amount)
(cond ((null? stil-list)
(reverse rl))
((> init amount)
(let* ((rl-lngth (length rl))
(st-l-lngth (length stil-list))
(pt-stil-l
(make-list (abs (- rl-lngth st-l-lngth)) point-stencil)))
(cons
(if (< rl-lngth st-l-lngth)
(append (reverse rl) pt-stil-l)
(reverse rl))
(if (< st-l-lngth rl-lngth)
(append stil-list pt-stil-l)
stil-list))))
(else
(split-stil-list
(cdr stil-list)
(cons (car stil-list) rl)
(+ init (interval-length (ly:stencil-extent (car stil-list) Y)))
amount))))
#(define-markup-list-command (wordwrap-two-columns-lines layout props args)
(markup-list?)
#:properties ((baseline-skip)
(amount 20)
(padding 10)
wordwrap-internal-markup-list)
(let* ((stils
(space-lines
baseline-skip
(interpret-markup-list
layout
props
(make-wordwrap-internal-markup-list #f args))))
(divided-stils (split-stil-list stils '() 0 amount))
(max-X-length-first-column
(apply max 0
(map
(lambda (stil) (cdr (ly:stencil-extent stil X)))
(car divided-stils)))))
(map
(lambda (s t)
(ly:stencil-add
s
(ly:stencil-translate-axis
t
(+ padding max-X-length-first-column)
X)))
(car divided-stils)
(cdr divided-stils))))
%% for testing of page-break-behaviour uncomment:
