Lua 文件处理

一、文件读存：  
\-- 似乎不支持大文件(不能超过9k?)  
function FileSaveLoad()  
      local file = io.open("c:\\\\in.lua", "r");  
      assert(file);  
      local data = file:read("\*a"); \-- 读取所有内容  
      file:close();  
      file = io.open("c:\\\\out.lua", "w");  
      assert(file);  
      file:write(data);  
      file:close();  
end  
FileSaveLoad();  
  
二、非循环表格处理：

HERO = 1;  
MONSTER = 2;  
BUILDING = 3;  
SUMUNIT = 4;  
cha = \{\};  
cha\[1\] =   
\{   
      basic =   
      \{   
      Name = "农民",    \--NPC名字  
      cha\_type = HERO,  \--NPC模型  
      \},  
      combat =   
      \{   
       acquire = 600.00,  \--主动攻击范围  
       basic\_def = 10,   \--基础防御  
      \},  
\};

function SaveTableContent(file, obj)  
      local szType = type(obj);  
      print(szType);  
      if szType == "number" then  
            file:write(obj);  
      elseif szType == "string" then  
            file:write(string.format("%q", obj));  
      elseif szType == "table" then  
            \--把table的内容格式化写入文件  
            file:write("\{\\n");  
            for i, v in pairs(obj) do  
                  file:write("\[");  
                  SaveTableContent(file, i);  
                  file:write("\]=\\n");  
                  SaveTableContent(file, v);  
                  file:write(", \\n");  
             end  
            file:write("\}\\n");  
      else  
      error("can't serialize a "..szType);  
      end  
end

function SaveTable()  
      local file = io.open("e:\\\\00\_00\_00\_海外组\_学习\\\\写入.txt", "w");  
      assert(file);  
      file:write("cha = \{\}\\n");  
      file:write("cha\[1\] = \\n");  
      SaveTableContent(file, cha\[1\]);  
      file:write("\}\\n");  
      file:close();  
end

SaveTable();
