xException

This is Pretty beautiful error log, You can listen the error and then to do special job!

使用样例

local x_error = require("xexception")

function listenError(...)

print("need to restart ...")

local temp = { ... }  

local arg = select("1", temp) 

--返回第一个参数和其之后的所有参数 

for i=1,#arg do

        -- print(arg[i])
        
end 

end

x_error.setCallback(listenError)

--测试 tryCatchError

x_error.tryCatchError(function(arg)

for i=1,#arg do

        print("tryCatchError arg"..i, arg[i])
        
        -- error('error..')
        
        n = n/nil
end  

-- n = n/nil

end,10,11,12,"lua")

print()

-- 测试 catchException

x_error.catchException(function(arg)

for i=1,#arg do

        print("catchException arg"..i, arg[i])
        
        error('error..')
        
        -- n = n/nil
        
end  

-- n = n/nil

end,100,101,102,"lua") --输出为100,101,102,lua

print()

-- 测试使用x_error.try, x_error.catch 自定义逻辑

x_error.try {

    function ()
    
        error('hello error')
        
    end
    
   ,
   
   x_error.catch {
   
      function(error)
      
         print('custom error handler...',error)
         
      end
      
   }

}
