Hi Luis,
below my approach.
Several comments in code, file and png attached.
Hope there are no problems, I tested it with 2.16.2 up to 2.17.16 from
latest master.
\version "2.16.2" %% and higher
%% Although, it is public I didn't manage to get full acces to
%% `default-script-alist´ from/scm/script.scm.
%% It is possible to modify the values, though, I couldn't create a new
entry.
%%
%% Anyway, working on a copy of `default-script-alist´ guarantees no
bleed-over.
#(define my-script-alist default-script-alist)
%% Some crazy stencils :)
#(define my-crazy-stil
;; A longish ellipse
(ly:stencil-in-color
(make-partial-ellipse-stencil 4 0.5 10 10 0.13 #t #t)
1 0 0))
#(define my-crazy-stil-2
;; A small hexagon
(let* ((th 0.1)
;; Value @code{6} returns a hexagon, try others.
(alpha-step (/ (* 2 PI) 6))
(alpha-start (/ alpha-step 2))
(radius 0.7)
(polypoints
(let loop ((alpha alpha-start))
(if (> alpha (* 2 PI))
'()
(cons (* (abs radius) (sin alpha))
(cons (- 0 (* (abs radius) (cos alpha)))
(loop (+ alpha alpha-step))))))))
(ly:make-stencil `(polygon ',polypoints ,th #f))))
%% Two alists with the name of the new articulation and its settings.
#(define my-wish-list-1
`("ellipse"
. (
(avoid-slur . around)
(padding . 0.20)

%% A macro setting the lists from above in the copy of
`default-script-alist´
%% I didn't manage to program some looping, mapping ... How to do?
%% For now, every new script has to be inserted in a single run.
#(define-macro (set-my-script-alist! ls-1 ls-2)
"Creates a new key-value-pair, taken from ls-2, in ls-1"

%% To use in \notemode you may want to use:

%% Shortcuts.
