Battery Reminder

This is a simple Go program that reminds MacBook Pro users when the battery level is at 20% or 80% charge, to help prolong the battery life of the MacBook.

Purpose

The purpose of this program is to help MacBook Pro users optimize their battery usage and extend the lifespan of their MacBook's battery. By reminding the user when the battery level is at 20% or 80% charge, the user can avoid overcharging or completely discharging the battery, which can damage the battery and reduce its lifespan.

How to use

1. Clone this repository to your local machine.

2. Make sure you have Go installed on your machine.

3. Open a terminal window and navigate to the directory where the program is located.

4. Run the following command to build the program:

   make build
   

5. Run the program using the following command:

   ./build/battery-reminder
   

   The program will run in the background and monitor the battery level of your MacBook Pro. It will remind you with a sound when the battery level is at 20% or 80% charge.

   You can customize the sound files by modifying the paths to the sound files in the main() function of the code.

Running as a background process

To run the battery-reminder program as a background process using nohup, you can follow these steps:

1. Navigate to the directory where your battery-reminder program is located in a terminal window.

2. Run the following command to start your program as a background process:

   nohup ./build/battery-reminder > battery-reminder.log &
   

   This command starts your program in the background and redirects its output to a log file named battery-reminder.log. The & at the end of the command sends the process to the background.

3. To check the status of your program, you can run the following command:

   ps aux | grep battery-reminder
   

   This will show a list of all processes running on your system that contain the string "battery-reminder".

4. To stop your program, you can find its process ID (PID) using the ps command, and then use the kill command to stop it:

   ps aux | grep battery-reminder
   kill PID
   

   Replace PID with the process ID of your battery-reminder program.

That's it! Your battery-reminder program should now run as a background process using nohup. Note that this method does not automatically start your program when your Mac starts up, and you may need to manually start it each time you want to use it.

Compatibility

This program has been tested on macOS, but it may work on other operating systems that support the battery package in Go.
