1、先給出用到的字符串處理函數代碼

--字符串分割函數 --傳入字符串和分隔符，返回分割后的table function string.split(str, delimiter)if str==nil or str=='' or delimiter==nil thenreturn nilendlocal result = {}for match in (str..delimiter):gmatch("(.-)"..delimiter) dotable.insert(result, match)endreturn result end--字符串按位分割函數 --傳入字符串，返回分割后的table，必須為字母、數字，否則返回nil function string.gsplit(str)local str_tb = {}if string.len(str) ~= 0 thenfor i=1,string.len(str) donew_str= string.sub(str,i,i) if (string.byte(new_str) >=48 and string.byte(new_str) <=57) or (string.byte(new_str)>=65 and string.byte(new_str)<=90) or (string.byte(new_str)>=97 and string.byte(new_str)<=122) then table.insert(str_tb,string.sub(str,i,i)) elsereturn nilendendreturn str_tbelsereturn nilend endfunction string.trim(s)return (string.gsub(s, "^%s*(.-)%s*$", "%1")) end

?

2、表格對象代碼（class見我上上篇文章lua高階用法 OO的實現）

TableData = class()function TableData:ctor()self.data = {} endfunction TableData:GetById(id)local num = #self.datafor i=1,num doif(id==self.data[i].Id) thenreturn self.data[i];endendprint( string.format("nil==TableData:GetById(%d)",id)) return nil; end

?

3、給出讀表器代碼

require 'Utility/LuaStringExt' require 'Table/TableData'TableReader = {}function TableReader.ReadAllLines(text)return string.split(text,'\n') endfunction TableReader.IsEmptyLine(str)if(str=='' or str[0]=='#') thenreturn trueendreturn false endlocal TableFieldType = {INT = 0,FLOAT = 1,STRING = 2,UNKNOW = 3 }local Syntax_INT = 'INT' local Syntax_FLOAT = 'FLOAT' local Syntax_STRING = 'STRING'function TableReader.ParseType(str)local types = {}local fields = string.split(str,'\t')for i=1,#fields dolocal sytax = fields[i]if(Syntax_INT==sytax) thentable.insert(types,TableFieldType.INT)elseif(Syntax_FLOAT==sytax) thentable.insert(types,TableFieldType.FLOAT)elseif(Syntax_STRING==sytax) thentable.insert(types,TableFieldType.STRING)elsetable.insert(types,TableFieldType.UNKNOW)print('Error:',i,'unknow type['..sytax..']')endendreturn types endfunction TableReader.ParseField(str)local fieldsTable = {}local fields = string.split(str,'\t')for i=1,#fields dotable.insert(fieldsTable,fields[i])endreturn fieldsTable endfunction TableReader.ParseValue(fieldsTable,typeTable,str)local ret = {}local fields = string.split(str,'\t')for i=1,#fields doif(TableFieldType.INT==typeTable[i] or TableFieldType.FLOAT==typeTable[i]) thenret[fieldsTable[i]] = tonumber(fields[i])elseif(TableFieldType.STRING==typeTable[i]) thenret[fieldsTable[i]] = fields[i]elseprint('Error:ParseValue',i)endendreturn ret endfunction TableReader.LoadTable(text)local tab = TableData.new();local lines = TableReader.ReadAllLines(text)local lineNum = #lineslocal types = nillocal fieldsTable = nilfor i=1,lineNum dolocal str = string.trim(lines[i])if(not TableReader.IsEmptyLine(str)) thenif(nil==types) thentypes = TableReader.ParseType(str)elseif(nil==fieldsTable) thenfieldsTable = TableReader.ParseField(str)elsetable.insert(tab.data,TableReader.ParseValue(fieldsTable,types,str))endendendreturn tab end

?

4、使用代碼

local table = TableReader.LoadTable(str) local data = table:GetById(0) print(data.Desc)

?
