I have started playing with BOSL2's new NURBS functionality. I have a
couple of use cases where the most intuitive approach would be to evaluate
the spline up until some distance, or distance from the end. If BOSL's
NURBS library had a length function, I could then use something similar to
"nurbs_curve(control,r,u=[desired_length/spline_length]);" to find that
point.
Before taking the time to write my own nurbs_length, and similar functions,
I thought I would ask if anyone knows a trick with the current
functionality.
Thanks and best regards,

The nurbs support is new and a lot of accessory functions don’t exist. You
can probably cokpuye nurbs length by just swapping nurbs into the bezier
length function. Be aware that the parametrization is not uniform so your
proposed method will be approximate.

Linuxcnc has had nurbs for quite a while. It is not precise simply
because it is intended to be artistic. It may, or may not, actually hit
all the points specified depending on cutting tool geometry. I've given
it some exercise playing with the curves of a rifle barrel, but would
first have to build a toolpost grinder or belt sander. to actually get a
better finish on a barrel. It would also carve pleasing outlines on a
milling machine, but what I've made has always been "square" for correct
mounting reasons. Where I think it should shine for OpenSCAD might be in
designing junction fillets. We'll have to learn how ti use it. Someone
should undertake our use of it and show us how.

Thank you, Adrian. I know that OpenSCAD NURBS was just release last
November and is still quite new, and that many standard support functions
do not yet exist. So, I am NOT complaining ;-) I also know that there are
some numerical estimators for computing NURBS lengths ,and while they are
very accurate, they are still estimations. I'll look into this and see if
I can come up with something that functions now, and I can share it with
others with the intent of polishing it up to submit a pull request.
Thanks again.

If the nurbs function returns a path, why can't you simply use a length
function that returns the length of any path by adding the norms of
adjacent points?

Yes, you can estimate nurbs length by just adding up the polygon length.
Where questions arise is in deciding how finely to sample the nurbs----how
many polygon segments to use. I didn't write the bezier length code, but
it uses some measure to assess how much deviation there is between the
bezier and the polygon and refines the estimate when the deviation exceeds
a threshold.
