Nice one, but nothing I can do in spare time, I had a look, and CartoCSS
syntax is incompatible
with the way we handle SLD in a few ways, for example, a CSS style in carto
describes a full
map, N layers, whilst in GeoTools/GeoServer we have one SLD per layer, so a
single CSS would
have to be turned into N layers.
There is also a number of properties that have no direct translactions,
that we'd have to
implement support for.
Long story short: it can be done, but it would be a sizeable amount of
work, larger
than just doing a java version of the existing scala tooling (I'm not
calling it a port because
it's really a clean room implementation, I'm just keeping the same syntax).
So.. funding welcomed :-)
Cheers
