I've been happily playing with Ur/Web and am pleased with the results so far.
One problem I am stuck on however is creating a callback from Ur, in other
words, calling a C function that can then call Ur functions. Unless I am
misreading the docs this doesn't seem to be currently supported.
In looking at the generated C code, the api's generated are very straight
forward, would it be possible to simply call those from a C function or would
this have unintended consequences?
Glad to hear you're happy so far. :)
You're right that there is no documented support right now for calling
Ur functions from C. One big impediment is that function names are
"mangled" in a way that is intentionally unspecified and
nondeterministic, so it will not be easy to predictably identify an Ur
function from C.
You would certainly need to understand Ur region-based memory management
to call Ur functions safely.
Can you fill us in more on your big-picture context? Why do you want to
call Ur functions from C?
