RE: PATCH: true C coroutines -- yield across C stack from anywhere

["Jean-Christophe Capdevila" <jccapdevila@...>]

Hello!

Yeap, your little "CurriedLoops" thingy works...but you lost execution
performance...

If i'am not wrong, each call will generate "phantom" calls to CurriedLoops..

And i want if possible to fix this on the C/C++ side...

The most valuable solution will be to tell the vm to stay at current
instruction and not to go to next...

If anyone has a solution on the C/C++ side i take it...

But thanks guys.


JC.

function CurriedLoops(func)
  local unpack = unpack
  return function(...) return while func(unpack(arg)) do end end
end

Goto = CurriedLoops(Goto)
PlayAndWaitAnim = CurriedLoops(PlayAndWaitAnim)

And lo the second mechanism works but looks like the first form :-)
