I andrew, thanks for your help!

Very low... but I'm learning!
Your exemple was a big help, especially because the order of appearence of
the elements in my function wasn't good and didn't allowed me to add a
variable in the original markup...
So now I can add all the parameters I wanted:
\version "2.19.81"
hook =
#(let ((direction? (lambda (n) (= 1 (abs n)))))
(define-event-function (direction on-line lenght offset)
(direction? boolean? number? pair?)
(let* ((self-al (if on-line 0 0.31))
(self-al (if (= direction 1) (- self-al) self-al))
(hook-markup #{
\markup \path #0.12 #`((moveto 0 0)
(rlineto -0.85 0)
(rlineto 0 ,lenght))
#})
)
#{
\tweak self-alignment-Y $self-al
\tweak extra-offset #offset
\tweak extra-spacing-width #'(-0.5 . 0)
\finger \markup \scale #(cons 1 direction) #hook-markup
#})))
\layout {
\context {
\Voice
fingeringOrientations = #'(left)
}
}
\relative {
<e'\hook #DOWN ##t 3 #'(0.75 . 0)>4 <f\hook #DOWN ##f 6 #'(0.75 . 0)>
<f\hook #DOWN ##f 6 #'(0.75 . -1)>
}
I have two questions though:
1) As can see, the markup is centered aligned. If the lenght is higher, it
moves further from the note head. I can adjust it with my Y-offset command,
but I think there is a way to make it by default top aligned, no?
2) This solution adds a lot of numbers after the initial \hook command.
Isn't there a way to tell the function some default values for the "lenght"
and "offset" parameters I have added, and just tweak them if necessary in
the score?
