1 项目描述
在文本中查找替换对应的字符串,功能如下:
thisisbefore(self,func) 替换成thisisafter(func,self).
2详细设计
2.1字符串查找替换
string regexReplace(string sMsg,string sSreach,string sReplace) { string sRet = ""; std::regex rPattern(sSreach);//搜索串 sRet = std::regex_replace(sMsg,rPattern,sReplace); return sRet; }
@H_502_27@2.2self与func交换位置
string regexSelfChangePos(string sMsg) { string sFunc = ""; string sSelf = ""; std::smatch rPotRet; std::regex rPotPattern("[(](\\s*[a-zA-Z]+[0-9]*[a-zA-Z]+[0-9]*[.]*[a-zA-Z]+[0-9]*[a-zA-Z]+[0-9]*\\s*),(\\s*[a-zA-Z]+[0-9]*[a-zA-Z]+[0-9]*[.]*[a-zA-Z]+[0-9]*[a-zA-Z]+[0-9]*\\s*)[)]"); const std::sregex_token_iterator end; for (std::sregex_token_iterator itPot(sMsg.begin(),sMsg.end(),rPotPattern); itPot != end; ++itPot) { std::string sPot = *itPot; if (std::regex_search(sPot,rPotRet,rPotPattern)) { sFunc = rPotRet[1].str(); sSelf = rPotRet[2].str(); } } sFunc = regexDelBlank(sFunc); sSelf = regexDelBlank(sSelf); string tmp = sSelf + "Tmp"; sMsg = regexReplace(sMsg,sFunc,tmp); sMsg = regexReplace(sMsg,sSelf,sFunc); sMsg = regexReplace(sMsg,sFunc + "Tmp",sSelf); return sMsg; }
@H_502_27@2.3文件读写操作
int fileTest() { char* old_locale = _strdup(setlocale(LC_CTYPE,NULL)); setlocale(LC_CTYPE,"chs"); CString StrFileName("d:\\fileTest.lua"); CStdioFile TempFile,File; if (!File.Open(StrFileName,CFile::modeRead)) return -1; CString StrTempFileName = File.GetFileTitle() + CString(".tmp"); if (!TempFile.Open(StrTempFileName,CFile::modeCreate | CFile::modeReadWrite)) return -1; CString Str; while (File.ReadString(Str)) { string sMsg = (CStringA)Str; sMsg = clickDeal(sMsg); CString strNew(sMsg.c_str()); TempFile.WriteString(strNew + CString("\n")); } File.Close(); TempFile.Close(); CFile::Remove(StrFileName); CFile::Rename(StrTempFileName,StrFileName); printf("successful "); setlocale(LC_CTYPE,old_locale); //还原语言区域的设置 free(old_locale);//还原区域设定 return 0; }
