[Code] C++ Code to Filter BetterQuesting's QuestProgress.json File

[NTaterY]

After the recent server wipe, my friend group decided that we would try to continue playing on our own server using the world download. Something that I took notice of was a particularly large QuestProgress.json file...

After seeing this, I decided to filter the file to extract the data associated just with me and my friends. To do this, I wrote some jank C++ code available below. 

We were a group of five players, and after running the code, the file size is much, much smaller!

Feel free to use the code if you want to filter your quest data out of the same file.

#include <fstream>
#include <iostream>
#include <string>
#include <vector>

using namespace std;

const vector<string> UUIDs = {""}; // INSERT UUIDs here
const int num_players = UUIDs.size();

bool matchesUUID(string uuid)
{
    for (int i = 0; i < num_players; i++)
    {
        if(!uuid.compare(UUIDs[i])) return 1;
    }
    return 0;
}

int main()
{
    ifstream input("QuestProgress.json");

    ofstream output("QuestProgressNew.json");

    string buffer[20];
    string line;

    for (int i = 0; i < 2; i++)
    {
        getline(input, line);
        output << line << endl;
    }

    getline(input, line);
    while(line.find("}") == string::npos)
    {
        output << line << endl;
        getline(input, line);
        output << line << endl;
        getline(input, line);
        output << line;

        bool hasMatch = 0;

        if (line.find("}") == string::npos)
        {
            int number = 0;

            getline(input, line);
            while (line.find('}') == string::npos)
            {
                buffer[0] = line;
                getline(input, line);
                buffer[1] = line;

                getline(input, line);
                string uuid = line.substr(line.rfind(":") + 3, 36);

                if (matchesUUID(uuid))
                {
                    if (hasMatch == 0) output << endl;

                    number++;

                    output << buffer[0] << endl << buffer[1] << endl << line << endl;

Awesome!

I like that type of players that try to program Java or C++, they make their world more personal ^^

Gawd looking at this code reminded me how much I hate C++ lol. pointers suck
