=====
|
|
|
|
A simple Lua wrapper for pthreads.
|
|
|
|
Each thread gets it's own `lua_State` and there is no shared global state.
|
|
The parent thread can pass data to a child thread only as parameters when creating
|
|
the child thread. The child threads can return data back to the parent thread only
|
|
when it return (i.e. ends). The parent needs to call child:join() to get the return
|
|
values from a child thread, this call will block until the child thread ends.
|
|
|
|
The design goals of this module is only provide support for creating new `lua_State`
|
|
and running them in a different thread. This module will not provide any
|
|
methods of thread-to-thread data passing between running threads (i.e. no locks, no shared state).
|

|
Thread to Thread communication methods
|
|
======================================
|
|
|
|
* The recommend method of passing data between threads is to use [ZeroMQ](http://github.com/Neopallium/lua-zmq).
|
|
|
|
* Another method is to use sockets library like [LuaSocket](http://w3.impa.br/~diego/software/luasocket) or [Nixio](http://neopallium.github.com/nixio/).

Installation
|
|
============
|
|
|
|
With LuaRocks 2.0.4.1:
|
|
$ sudo luarocks install https://github.com/Neopallium/lua-llthreads/raw/master/rockspecs/lua-llthreads-scm-0.rockspec
|
|
|
|
With CMake:
|
|
$ git clone git://github.com/Neopallium/lua-llthreads.git
|
|
$ cd lua-llthreads ; mkdir build ; cd build
|
|
$ cmake ..
|
|
$ make
|
|
$ sudo make install
|
|
|
|
|
|
Example usage
|
|
=============
|
|
|
|
local llthreads = require"llthreads"
|
|
|
|
local thread_code = [[
|
|
-- print thread's parameter.
|
|
print("CHILD: received params:", ...)
|
|
-- return all thread's parameters back to the parent thread.
|
|
return ...
|
|
]]
|
|
|
|
-- create child thread.
|
|
local thread = llthreads.new(thread_code, "number:", 1234, "nil:", nil, "bool:", true)
|
|
-- start joinable child thread.
|
|
assert(thread:start())
|
|
print("PARENT: child returned: ", thread:join())
