Hi Adam,
There's a way to turn LilyPond markup commands like \draw-line into
Scheme expressions; the method is documented in 12.4.1 "Markup
construction in Scheme" in the 2.11 version of the manual; and I think
the concept is exactly the same in 2.10.
So maybe this will work ...
\once \override TextSpanner #'edge-text = #(cons
(markup #:draw-line '(0 . -1))
(markup #:draw-line '(0 . -1)))
... though, again, I don't have a 2.10 install loaded to test with.
Does this get it?

Hello,
the problem is that I can't figure out how to set up the #'edge-text
property to draw the lines (the markup doesn't accept the draw-line
command, and it's not included in the list of valid markup commands for
2.10.10). Now I've spent at about an hour with adopting the code that I
got a few days ago for Bartok-pizz to make it able to draw a line (as
the Bartok-pizz sign has a line included), with the following code:
\override TextSpanner #'edge-text = #(cons (markup #:stencil
(ly:stencil-add
(ly:make-stencil
(list 'draw-line x1 x2 x3 x4 x5)
'(x6 . x7) '(x8 . x9)
)
)
) (markup #:stencil
(ly:stencil-add
(ly:make-stencil
(list 'draw-line x10 x11 x12 x13 x14)
'(x15 . x16) '(x17 . x18)
)
)
) )
where the values x1-x18 are number parameters. The problem is, that I'm
googleing and searching every documentation I've found, but I can't
guess the meaning of these 18 parameters (in fact, just 9, as the other
9 are supposed to mean the same thing).
Could anybody explain for me what these numbers mean, and how to force
them to draw a simple vertical line which fits to the textspanner's line?
Thank you,
Adam
P.S. Sorry for the many questions I'm posting, but I started using
Lilypond a week ago or so, and I couldn't find up to now an acceptable
reference manual for it (so, a collection of documents that contain
every possible command with their every possible parameters and values,
like for example the javadocs for Java). Does exist this kind of
documentation somewhere?
