Lua 完美打印数据 （例子）

例子1 ：

 ableprint = function(data,cstring,deepIndex)  --第二个参数可以为空，第三个参数不要手动添加，它是用来进行打印深度控制的。
     if data == nil then
         print("core.print data is nil");
     end

     if deepIndex == nil then deepIndex =  end
     if cstring == nil then cstring = "" end

     local cs = cstring .. " ";
     print(cstring .."{");
     if(type(data)=="table") then
         for k, v in pairs(data) do
             if(type(v) == "table") then print(cs..tostring(k).." = ");
             else print(cs..tostring(k).." = "..tostring(v)); end

             if(type(v)=="table") then

                 if (deepIndex + ) <  then  --5就是控制的打印深度(你可以根据需要调整)，以防数据结构中存在循环饮用(别以为不可能，我就遇到过)
                     zr.tableprint(v,cs,(deepIndex+));
                 else
                     print(cs.." {"..tostring(v).."}");
                 end
             end
         end
     else
         print(cs..tostring(data));
     end
     print(cstring .."}");
 end

例子2：

 function var_dump(data, max_level, prefix)
     if type(prefix) ~= "string" then
         prefix = ""
     end
     if type(data) ~= "table" then
         print(prefix .. tostring(data))
     else
         print(data)
         if max_level ~=  then
             local prefix_next = prefix .. "    "
             print(prefix .. "{")
             for k,v in pairs(data) do
                 io.stdout:write(prefix_next .. k .. " = ")
                 if type(v) ~= "table" or (type(max_level) == "number" and max_level <= ) then
                     print(v)
                 else
                     if max_level == nil then
                         var_dump(v, nil, prefix_next)
                     else
                         var_dump(v, max_level - , prefix_next)
                     end
                 end
             end
             print(prefix .. "}")
         end
     end
 end
