batalert

batalert (aka Battery Alert) is a tool, written in Ruby, to notify the users when their battery is either under-charged (default: < 10%) or over-charged (default: > 90%).

notify the users when their battery is either under-charged (default: < 10%) or over-charged (default: > 90%).

Ever ran out of battery whilst in the middle of work?
Well, say no more! batalert has got you covered!
Just consider installing it and put it on cron so that you never have to worry about running out of battery in midst of your work! Isn't that...amazing? 🚀

This is originally intended for WM users who don't get battery notifications by default, but can be used by everyone who sees its worth!

How does it work?

Batlalert upon being set up, shall notify you when to put your battery on charging and when to unplug it too. Whilst notifying so, it also numerically mentions your battery percentage at that particular moment.

• Install the gem from the rubygems archive:
  $ gem install batalert

• Install the package via apt (only for Debian Sid and Bullseye):
  $ sudo apt install batalert

• Download the deb and install it manually:
  The release page has a .deb binary which can be downloaded with a single click. Once done, run:
  $ sudo dpkg -i <path-to-deb>/batalert_<version>_all.deb

• Set it up manually:
  $ crontab -e

  And then add a line in the following format at the end:
  */n * * * * /usr/bin/batalert

  NOTE: n is the duration of interval (in minutes) after which the binary is executed. So, for instance, if you want to schedule a cron after every 15 minutes (that's what I do), then the line becomes:
  */15 * * * * /usr/bin/batalert

• Use whenever to schedule the cron automatically on your behalf:
  (you can install whenever via gem install whenever or apt install ruby-whenever)

  • Clone this repository:
    $ git clone https://github.com/utkarsh2102/batalert.git
  • Move to its directory:
    $ cd batalert
  • Set the value of interval in config/schedule.rb.
  • Run whenever to schedule the cron:
    $ whenever --update-crontab

After checking out the repo, run bin/setup to install dependencies.
Then, run rake to run the tests.
You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install.
To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.
