# jello

A tiny single file header only logging library for C++23

This library makes use of std::print and std::format so make sure your compiler supports this!

## Example

```cpp

// this is optional, will default to logging everything and not writing to log files

jello::configure(

    jello::Level::Info, // the debug message will no longer be shown :)

    "./test.log"        // the logs are now also printed to a file

);

jello::debug("Hello, World!");

jello::info("Hello, World!");

jello::warning("Hello, World!");

jello::error("Hello, World!");

jello::fatal("Hello, World!");

```

![Output example](./.github/screenshot.png)

Example: Overwrite raylib logging

```cpp

SetTraceLogCallback([](int message_type, const char* text, va_list args) {

    std::vector buffer(1024);

    auto size = vsprintf(buffer.data(), text, args);

    std::string log_str {buffer.begin(), buffer.begin() + size};

    switch (message_type) {

    case LOG_TRACE:

        jello::debug("TRACE {}", log_str);

        break;

    case LOG_DEBUG:

        jello::debug(log_str);

        break;

    case LOG_INFO:

        jello::info(log_str);

        break;

    case LOG_WARNING:

        jello::warning(log_str);

        break;

    case LOG_ERROR:

        jello::error(log_str);

        break;

    case LOG_FATAL:

        jello::fatal(log_str);

        break;

    }

});

```
