devel/luacopas 1.1.6p3 OpenBSD

Copas is a dispatcher based on coroutines that can be used by TCP/IP socket request/response servers. It uses LuaSocket as the interface with the TCP/IP stack.

A server registered with Copas should provide a handler for requests and use Copas socket functions to send the response. Copas loops through requests and invokes the corresponding handlers.

Since Copas is coroutine based, using it within a pcall or xpcall context does not work with Lua 5.1 yielding. If you need to use those functions we strongly suggest using Xavante's coxpcall, a coroutine safe version of the Lua 5.1 protected calls.
