THIS PROJECT HAS MOVED TO GITHUB.

jsoncpp is an implementation of a JSON (http://json.org) reader and writer in C++. JSON (JavaScript Object Notation) is a lightweight data-interchange format. It is easy for humans to read and write. It is easy for machines to parse and generate.

User Reviews

  • Robust, small and standard de facto implementation of JSON parser in C++. We use it in educational purposes to study students.
  • We have been using Json-cpp for quite a number of years in our mobile games, where it has provided solid, reliable, cross-platform parsing with a very small footprint.
  • hello author, I find a bug. when i use reader prase a num string,expleme "49", it is crash type_ is int type,but value_.map_ is not createed
  • hello author, I find two bug. 1.if json more than twenty value,Could lead to a loss of "[" and "{". example: Json::Value root; Json::FastWriter writer; while(bContinue) { hModule = CreateToolhelp32Snapshot(TH32CS_SNAPMODULE, PInfo.th32ProcessID); Module32First(hModule, &MInfo); CloseHandle(hModule); hProcess = OpenProcess(PROCESS_QUERY_INFORMATION,FALSE,PInfo.th32ProcessID); char cFull[1024] = {0}; int iLen = pGetProcessImageFileNameA(hProcess,cFull,1024); Json::Value sysinfo; sysinfo["dwPid"] = (int)PInfo.th32ProcessID; sysinfo["FileName"] = PInfo.szExeFile; sysinfo["FilePath"] = DosDevicePath2LogicalPath(cFull); sysinfo["dwThreads"] = (int)PInfo.cntThreads; sysinfo["dwPriClass"] = (int)GetPriorityClass(hProcess); root.append(sysinfo); bContinue = Process32Next(hSnapshot, &PInfo); } jsondata = writer.write(root); FILE *fp; fp = fopen("aa.txt", "w"); if(fp ==NULL) printf("fails\n"); fprintf(fp, jsondata.c_str()); 2.value["key"] funtion lost aslong(),if value is FileSize. If updated, please notice 674268015@qq.com,Thank you very much.
  • hello author, I find a expression that in json_reader.cpp 566 line. like this: bool badTokenType = ( token.type_ == tokenArraySeparator && token.type_ == tokenArrayEnd ); the boolean expression always return false. I think not '&&' but '||', do you thing so ?
