lua-websockets for lua 5.2

[dehmel.r@...]

Hi,
I have installed lua-websockets with
copas (luarocks install lua-websockets) for lua 5.2 and run into some problems.
Here is my way to solve this problems:

1. I have only lua 5.2 on my Windows
7 and the MinGW compiler.
2. luarocks install lua-websockets
3. Trying to start a test program with
websockets: "lua5.1.dll is missing"
-> pack.dll depends on lua5.1.dll
-> down load the src rock of lpack
-> trying to compile:
--> failed because of lpack.c line:254
luaL_reg the header of lua 5.2 has this type "luaL_Reg"
--> now the pack.dll can be recompiled
with lua 5.2 and linked to lua52.dll
-> trying a websockets test application
--> failed because of "rol"
is nil. Problem is in websockets->tools.lua line:3 local rol = bit.rol
--> because bit32 (the bit replacement
in lua 5.2) has changed the name "rol" to "lrotate"
--> changing line:3 to local rol
= bit.lrotate
-> now the winsocket test application
works fine,

BUT only the test application:
In my application I have to add a thread
to copas. I use this example from the copas manual:
local socket = require("socket")
local copas = require("copas.timer")

local host = "127.0.0.1"
local port = 10000

local skt = socket.connect(host, port)

copas.addthread(function()
   while true do
      print("receiving...")
      local resp = copas.receive(skt, 6)
      print("received:", resp or "nil")
      if resp and resp:sub(1,4) == "quit" then
         skt:close()
         break
      end
   end
end)

copas.loop()

--> this example misses one important
thing:
skt:settimeout(0)
without this addthread() blocks during
the (internal) first call of the thread function before the copas loop
can be started.

Now every thing looks fine!

I'm new in this mailing list - is this
the right place for this information?
