Re: self-alignment-X on DynamicTextSpanner?
Thanks, Jean and Valentin, for the replies. I’ll certainly be able to
achieve the result that I want.
However, I do think that DynamicTextSpanner should simply use properties
bound-details.left.self-alignment-X and
bound-details.left.parent-alignment-X
for this, by default. attach-dir doesn’t seem very descriptive and it
deviates from the way horizontal alignment is normally specified in
LilyPond, and likewise being able to specify self-alignment-X would seem
to be the normal thing to expect.
I’ll submit such a request to the bug list.
Best, Simon

Hello Simon,
You need to use bound-details.left for these kind of things. There you have
the property attach-dir, which acts like parent-alignment-X for the endpoint.
This one defaults to LEFT, so you cannot really get any further by this. The
other way is to use the text property to add a \right-align to have the actual
markup aligned to the right (you might want to change attach-dir to CENTER, as
the fff does the same.
We can infact add some sugar for this, like here.
Cheers,
Valentin

To explain the behavior with left-bound-info: this is an
internal property that gets populated with values from
bound-details and values computed automatically. If you
override a subproperty, since callbacks aren't supported
for subproperties, you just override the calculation of
this property from bound-details and logic, and there
is nothing in it but the suboverride you have done.
Then it's not surprising that everything starts going
wrong.
To answer the question: attach-dir is the equivalent of
parent-alignment-X, controlling where on the note head
(left, center, right, intermediate values) the reference
point of the text goes. There is no direct equivalent
for self-alignment-X, but you can do
\version "2.22.1"
{
1-\tweak self-alignment-X 1 \fff
1\tweak bound-details.left.text \markup \general-align #X #0 "cresc."
