在Lua车道之间共享一个全局变量

Question

我想在两个车道之间共享一个全局变量，想法是当lane1更新一个共享变量时，我应该能够在车道2得到预定时获得它的更新值。有针对这个的解决方法吗？

代码片段如下： -

shared_variable = 0 
local function lane1() 
    .. 
    shared_variable = shared_variable + 1 
end 

local function lane2() 
    .. 
    print(shared_variable)-->shared variable is not getting updated,always prints 0 
end 

Thread1= lanes.gen("*",{globals = _G},lane1) 
Thread2= lanes.gen("*",{globals = _G},lane2) 

T1 = Thread1() 
T2 = Thread2() 

T1:join() 
T2:join() 

Answer 1

下面是示例实现wh ERE我们可以分享车道之间的varible（使用设置& get方法）

你告诉

require("lanes") 

shared_variable = 0 

local linda = lanes.linda() 

local function lane1() 
    while true do 
     shared_variable = shared_variable + 1 
     linda:set("var", shared_variable) 
    end 
end 

local function lane2() 
    while true do 
     local v = linda:get("var") 
     print(v) 
    end 
end 

Thread1= lanes.gen("*",{globals = _G},lane1) 
Thread2= lanes.gen("*",{globals = _G},lane2) 

T1 = Thread1() 
T2 = Thread2() 

T1:join() 
T2:join() 

Answer 2

你将不得不使用林多斯的变量自己同步 - 这里的文档：

而且这里是你的代码的固定版本：

require("lanes") 

shared_variable = 0 

local linda = lanes.linda() 

local function lane1() 
    while true do 
     shared_variable = shared_variable + 1 
     linda:send("var", shared_variable) 
    end 
end 

local function lane2() 
    while true do 
     local v = linda:receive("var") 
     print(v) 
    end 
end 

Thread1= lanes.gen("*",{globals = _G},lane1) 
Thread2= lanes.gen("*",{globals = _G},lane2) 

T1 = Thread1() 
T2 = Thread2() 

T1:join() 
T2:join()
