1 Why lowbat?

- I've been using minimalist OS installations for work, personnal computing and playing video games for a while now. - I used Arch Linux, I still use Gentoo Linux - which is by far my favorite Linux distribution - as a desktop OS, and now I am using - FreeBSD on my workstation. + I've been using minimalist OS installations for work, personnal computing + and playing video games for a while now.

- Those operating systems and distributions basically come with a kernel, coreutils, a shell and that's pretty much it. - Everything else has to be installed manually. I love this philosophy, the simplicity behind it and the fact that - you know exactly what's on your system at any moment. + Those operating systems and distributions basically come with a kernel, + coreutils, a shell and that's pretty much it.

- As window managers, I used dwm for a while, and I am now using bspwm. They are ultra-fast, very lightweight and do not bring - extra bloatware to my systems. I do not use a status bar as well, I like my applications to use the full screen space available. + As window managers, I used dwm for a while, and I am now using bspwm.

- A big problem for me with this setup for me was that they do not come with some kind of warning or notification system, - like fancier desktop environments would, when my laptop battery is low. That also was before I started using Emacs, discovering - the battery level indicator in the modeline. Ultimatly the frustration was too important when the computer kept shutting down in - the middle of important work too many time. Then I decided to create lowbat to cure this issue. + A big problem for me with this setup for me was that they do not come with some + kind of warning or notification system, like fancier desktop environments would, + when my laptop battery is low.

2 History of lowbat

+

- It started as a very short dash shell (get dash here) script that was working fine but I wanted to experiment a little bit with this. - It turned into a C++ program, which is still the case for the GNU/Linux version. Switching to FreeBSD, I exerimented again by - turning it into an x64 assembly program, following the Intel syntax. These days, I am rewriting it with the AT&T syntax. + It started as a very short dash shell (get dash here) script that was + working fine but I wanted to experiment a little bit with this.

3 How it works

+
+
+
+

3.1 libnotify lowbat

+
+

+ The principle of lowbat is rather simple. When it's running in the + background, it checks every 4 minutes whether your battery is above 15%. + If that is the case, it sleeps for another 4 minutes. When your battery runs + bellow 15%, lowbat checks your battery level every 20 seconds as well as + sending you a notification using libnotify. You can display live + notifications on your desktop using dunst for example, as well as many + other I'm sure. +

+ + +

3.2 espeak lowbat

+
+

+ lowbat also has an option to send a custom voice message to the use + using espeak. Very handy if you are not in front of your computer or + if you want to bring joy to this dramatic event. +

+
+
+ +
+

3.3 unknown lowbat

+
+

+ Sadly, I wasn't able to test lowbat on machines with more that one + battery. My call is that it will only warn you for the first battery, + but I can't be sure. Try it and tell me! +
