The point of this Rant is clear. You needed to ventilate and you're doing some reflection.

Well, boost is a bit scary, it's freaking huge. I do not have much experience in C++ but I did write a basic server application with it once using Boost and I was like WTF during compiling that HUGE thing. Also, I did not really like how it did provide the service. The API. It was very, very abstract. Knowing what code it executes behind it (dem C sockets) it didn't feel good.

Now you know how a JS dev feels or should feel. Overwhelmed, knowing that 99% of the application is not yours.

How does that feel?

@retoor So I have used boost.asio before. I am fine with it being a black box. It did what I wanted in the past and was simple to use, even with threading. I want to use it again and the hard part has been getting libraries installed. I expect the boost.asio usage to be easy. I dunno. Someone smarter than me wrote it. I don't want to write a json parser or networking code. I want an app that does a thing.

@Demolishun parser and networking code is fun as f. Generating code is for losers. But you know what? It doesn't count if someone else does it for you. i'll help you out buddy!

@chatgpt write a minimal json parser in C++ from scratch.

Sure! Here is a minimal JSON parser in C++ from scratch:

```cpp
#include <iostream>
#include <fstream>
#include <string>
#include <map>

class JsonParser {
public:
std::map<std::string, std::string> parse(const std::string& filename) {
std::map<std::string, std::string> data;

std::ifstream file(filename);
if (!file.is_open()) {
std::cerr << "Error opening file: " << filename << std::endl;
return data;
}

std::string line;
while (std::getline(file, line)) {
size_t keyStart = line.find("\"") + 1;
size_t keyEnd = line.find("\"", keyStart);
size_t valueStart = line.find(":", keyEnd) + 1;

if (keyStart == std::string::npos || keyEnd == std::string::npos || valueStart == std::string::npos) {
continue;
}

std::string key = line.substr(keyStart, keyEnd - keyStart);
std::string value = line.substr(valueStart);

data[key] = value;
}

file.close();
return data;
}
};

int main() {
JsonParser parser;
std::map<std::string, std::string> jsonData = parser.parse("data.json");

for (const auto& pair : jsonData) {
std::cout << pair.first << ": " << pair.second << std::endl;
}

return 0;
}
```

In this code snippet, we create a `JsonParser` class with a `parse` method that reads a JSON file line by line, extracts key-value pairs by finding key and value strings, and stores them in a map. We then use the `main` function to run the parser on a sample JSON file `data.json` and print out the parsed key-value pairs. This parser is very minimal and may need to be expanded for more complex JSON structures.

@Demolishun wtf, it obviously misses some escaping code for strings but depended on your input source I would totally use it. This is actually great stuff. Did not expect it to be so clean. Wtf, what would've you've done without me? oh oh oh :)

What has been seen cannot be unseen. USE IT! :)

Oh, I noticed on every search, the AI response was so wrong it was pathetic. Not once did it lead to a solution. It said things existed that simply did not.

@Demolishun yeah, this one seems to do only one kv paid, not even multiple I see. I don't see comma handling. But if you give it some love for a hour, maybe two, you could consume the love. As long you're not handling user input that could produce an escape issue it's a valid solution. What is two hours in the C++ world for such feature? Not a lot I guess. Also, you know exactly what happens now.

I would prefer this above boost. Also, I'm sure that it's multiplatform.

Good night.
