microlog 6: New feature – Log Topics

Andrei Gramakov — Wed, 18 Sep 2024 20:18:30 +0000

Hi!

I continue developing my logging library. I’m not getting much positive response from the internet, but the developing itself is too fun, so I continue adding new features (and use them in my other projects 🙂)

This time I added log topics. Each log message can have a topic, and you can control whether to print messages from each topic. It does not pollute the output with unnecessary messages and is very handy during debugging. Here is an example from a testing desktop application

And here is a real-life example from my Raspberry Pi Pico-based remotion project:

As usual, here is the link to the repository:

For this release, I’ve put extra effort into the README file so you can find examples of usage for every feature. All the functions are documented in the header file, but if you have any questions or proposals, drop me a message, and I’ll try to respond.

Happy coding!

New Release: microlog 5.1.0

Here is a new version of microlog with improved custom callback handling.

It is not always simple to redirect printf output on some platforms. For this in the last release, I’ve added a new ulog_add_callback function.

void arduino_callback(ulog_Event *ev, void *arg) {
    static char buffer[128];
    ulog_event_to_cstr(ev, buffer, sizeof(buffer));
    Serial.println(buffer);
}

...

ulog_add_callback(arduino_callback, NULL, LOG_INFO);

microlog is a C-based thread-save portable and customizable logging library, aiming to provide powerful functionality while keeping the usage intuitive and the learning curve shallow. microlog can be quickly integrated to any project by copying 2 files or as a meson/cmake subproject.
