Lua concurrency using channels and coroutines

L3C - Lua concurrency using channels and coroutines

L3C is Lua library for concurrent programming. It's two basic concurrency primitives are lightweight cooperative threads and communication channels.

The project is under heavy development.

Example:

local function to(ch1, ch2)
   while true do
      local x = recv(ch1)
      send(ch2, x + 1)
   end
end

local function from()
   local ch1 = chan()
   local ch2 = chan()

   local ch3 = chan()
   local ch4 = chan()
   
   go (to, ch1, ch2)
   go (to, ch3, ch4)

   local x = 0
   send(ch1, x)
   while x < 20 do
      x = recv(ch2)
      print (x)
      send(ch3, x)
      x = recv(ch4)
      print (x)
      send(ch1, x)
   end
end
