Does umka lang supports reentrancy?

Does umka lang supports reentrancy?
meaning you can safely re-enter the scripting engine from a native (C/C++) callback invoked by a script - e.g., a script calls a registered native function, which then executes another script function on the same VM instance.
Also what is use of pointers in umka lang while no other scripting languages have pointers (for sandboxing no pointers is required)

• Reentrancy. It depends. You cannot call Umka functions from different OS threads. However, you can do it staying on the same thread:
  https://github.com/vtereshkov/umka-lang/blob/master/tests/lib/lib.um#L6
  https://github.com/vtereshkov/umka-lang/blob/master/tests/lib/lib.c#L85

• Pointers. I would say it's the opposite: all other scripting languages have pointers for representing any structures, while almost none of them have structures as values. Their pointers are not called pointers, just because you never have to dereference them explicitly.
  Umka was designed to support any C structures natively. C distinguishes between struct {struct S data;} and struct {struct S *data;}, and so does Umka! You always know the actual memory layout of any Umka structure and can find a one-to-one correspondence in C.

After undef FORCE_INLINE umka compiled in 1.2 seconds.
changing FORCE_INLINE to inline (#define FORCE_INLINE inline) umka compiled in 1.5 seconds. I will leave it defined as inline as compiler will do whatever inlining it feels necessary instead of no inlining.
Amazing.
I was worried about increased link time of my own project after linking the lib (like with angel script big static lib, and chaiscript being fully templates compiles everything every time)

Do I need to include umka.c also in static lib?

[vtereshkov]

No. The fact that you're linking your app against the Umka static lib means that it's your app, rather than umka.c, should call the lib.

Is there a discord or forum also for umka lang?
