Re: Upline articulation
Hi Malte and Thomas,
This is all really great and appreciated.
But where are these functions located, or, dare I ask, documented?

If I understand correctly, that's not entirely correct.
In general, a markup-command is done by the macro `define-markup-command'.
We get two procedures from it, in this case: `draw-line-markup' and
`make-draw-line-markup'.
See:
#(format #t "\ndraw-line-markup:\n~y"
draw-line-markup)
#(format #t "\nmake-draw-line-markup:\n~y"
make-draw-line-markup)
As you can see from the displayed results `draw-line-markup' needs
three arguments. Two of them are the default `layout' and `props'
`make-draw-line-markup' only one. The default ones are already done.
That's the reason why we can do
$(make-draw-line-markup '(0 . 1)) without anything else.
Using `draw-line-markup' would need to have those defaults arguments supplied.
In ly-syntax this automatically happens while doing
\markup \draw-line ...
But it's possible to use 'draw-line-markup' directly:
{
\override Beam.stencil =
#(draw-line-markup
$defaultpaper
(list (ly:output-def-lookup $defaultpaper 'text-font-defaults))
'(1 . 1))
c'8[]
}
A little strange and inconvenient, but possible...
So I think it's important to know that while using
`make-draw-line-markup' we use a procedure.
Whereas $(markup #:draw-line '(0 . 1)) will be transformed.
Makes a difference for some involved scheme-coding...
That said, for the most use-cases below is fine and doable:

Cheers,

P.S. I hope I made myself clear, not that easy for me to explain
complex stuff as a non-native speaker.

The function make-draw-line-markup is the markup command draw-line that
can be used as
#(make-draw-line-markup '(0 . 1))
or
\markup \draw-line #'(0 . 1)
or
#(markup #:draw-line '(0 . 1)
Same for all other markup commands.
So you can just replace the line
(make-draw-line-markup '(0 . 1)))
in your original code by
(make-override-markup '(thickness . 3)
(make-draw-line-markup '(0 . 1)
or by
(markup #:override '(thickness . 3)
#:draw-line '(0 . 1
or by
#{ \markup \override #'(thickness . 3)
\draw-line #'(0 . 1) #}))

Upline articulation
I need a custom articulation common in 18 c scores which is a short vertical line above the note. I have the following code which works just fine: upline = #(let ((m (make-articulation "stopped"))) (set! (ly:music-property m 'tweaks) (acons 'font-size 3 (acons 'stencil (lambda (grob) (grob-interpret-markup grob (make-draw-line-markup '(0 . 1 (ly:music-property m 'tweaks m) I cannot recall where I obtained this code from. But I want to have the line thicker. I don't know how to modify this. Grepping the lilypond installation I am unable to find the function make-draw-line-markup. Where does that come from? Can I use another function that takes a thickness as an additional parameter? Andrew ___ lilypond-user mailing list lilypond-user@gnu.org https://lists.gnu.org/mailman/listinfo/lilypond-user
