lua中打印所以类型功能实现

本人测试 number、string、bool、nil、table嵌套table、userdata没问题 共享一下有什么问题请拍砖 代码如下 

cclog = function( ... )
    local tv = "\n"
    local xn = 0
    local function tvlinet(xn)
        -- body
        for i=1,xn do
            tv = tv.."\t"
        end
    end

    local function printTab(i,v)
        -- body
        if type(v) == "table" then
            tvlinet(xn)
            xn = xn + 1
            tv = tv..""..i..":Table{\n"
            table.foreach(v,printTab)
            tvlinet(xn)
            tv = tv.."}\n"
            xn = xn - 1
        elseif type(v) == nil then
            tvlinet(xn)
            tv = tv..i..":nil\n"
        else
            tvlinet(xn)
            tv = tv..i..":"..tostring(v).."\n" 
        end
    end
    local function dumpParam(tab)
        for i=1, #tab do  
            if tab[i] == nil then 
                tv = tv.."nil\t"
            elseif type(tab[i]) == "table" then 
                xn = xn + 1
                tv = tv.."\ntable{\n"
                table.foreach(tab[i],printTab)
                tv = tv.."\t}\n"
            else
                tv = tv..tostring(tab[i]).."\t"
            end
        end
    end
    local x = ...
    if type(x) == "table" then
        table.foreach(x,printTab)
    else
        dumpParam({...})
        -- table.foreach({...},printTab)
    end
    print(tv)
end

使用示例如下代码

    local ttt = {23,aa=23,23,
                    {bbb=23,"dsd",false,nil,
                        {32,ccc="23dd",
                            {23,"sdfsdf",
                                {234,addd="23233jjjjsdOK"}
                            }
                        }
                    },
                    {dd = "sd",23},
                true
                }

    cclog(23,"sdf",ttt,"sdssssf",323223,false)
