A program for tracking battery usage, remaining time, and health.
This program is intended specifically for use with Polybar because it just prints data to stdout. Additionally, while I created it to be used on Thinkpads (hence the name), I think it should work on just about any Linux laptop. I'm still pretty new to Linux and C, so don't quote me on that. The only thing that makes it designed for Thinkpads is that it finds multiple battery directories in /sys/class/power_supply and sums all their relevant energy info rather than only using a single battery like the default Polybar module does. However, it has additional functionality that the default module doesn't have, so it may still be worth using even with only 1 battery.
To create and install the binary, just run the following from the top-level directory:
make
install -m 755 thinkpattery /path/to/installationI like to install mine at ~/.local/bin but it's up to you.
Because I'm pretty new to C, configuration for this program is pretty limited and annoying to do. Most configuration-related variables are either a global const string or a macro. All icon consts can be found in battery_tracker.c, the macro for the exponential moving average alpha value can be found in moving_average.h (read about what changing the alpha value does here), and the update frequency macro (SAMPLE_FREQUENCY) can be found in common.h. All icons that I use are from Fontawesome, so you can either install that and use them as well or use your own icons.
