Hi Werner,

As I understand it, the \hspace defines the height of the entire
markup box -- i.e., it is explicitly taller than either the fermata
or the (e.g.) "1." -- and thus it is this "larger" box (as set by the
height of an \hspace object) that is affected by the spacing code.
You can also use this hint to line up custom dynamics with opposing
descenders and ascenders, e.g.,
pp gorgeous % all descenders
pp fantastic % all ascenders
will not line up "correctly" by default.
Nice. For the last year or so I've been using a transparent-f trick
for the same purpose, for example:
pppX = #(make-dynamic-script (markup #:combine
#:transparent #:dynamic "f"
#:line(#:hspace 0 #:dynamic "ppp" #:hspace 0)))
and
fffX = #(make-dynamic-script (markup #:combine
#:transparent #:dynamic "f"
#:line(#:hspace 0 #:dynamic "fff" #:hspace 0)))
It's looks like craziness, but writing c'4 \ppX c'4 \fffX causes the
dynamics to align absolutely perfectly once you've set
DynamicLineSpanner #'staff-padding.
I have a definition file of nothing but these custom dynamics that I
use exclusively. It's been more than a year since I've used a built-in
Lily dynamic like \pp or \ff because the vertical alignment with the
transparent-f trick is so much better. (I'd actually suggest changing
out the default dynamics definitions in the distro, but not sure if
that's the behavior anyone else would actually want.)
I think the magic settings you need to get the default (and custom)
dynamics
to align without having to resort to such tricks are:
\override DynamicLineSpanner #'Y-extent = #'(-1 . 1)
\override DynamicText #'Y-offset = #0
As far as I can see (and understand), this gives baseline alignment.
Similar tricks can be used to turn off top/bottom alignment
of text scripts:
\override TextScript #'minimum-Y-extent = #'(-1 . 1)
