Hi List,
for conciseness the example should be reduced even more (if someone
wants to post it to LSR I'd recommend this version).
%circled-pattern
#(define-markup-command
(circled-pattern layout props radius angle num arg)
(number? number? number? string?)
(interpret-markup layout props
(fold
(lambda (i prev)
(markup
(#:combine
(#:rotate
(* i (/ angle num))
(#:concat (#:null #:hspace radius arg)))
prev)))
(markup (#:null))
(iota (1+ num))))))
% Test (markup a 180° circled pattern with radius 5 and 17 dots) :
\markup\circled-pattern #5 #180 #16 #"."
% an upside down pattern can be achieved with a negative angle:
\markup\circled-pattern #5 #-180 #16 #"."
