A keep alive program for Linux/GNOME, inspired by caffeinate(8) on MacOS.

You may install keal using gem install keal, however, this will not install the systemd unit file. So, for now, the recommended way to install keal is:

git clone https://github.com/pinecat/keal
cd keal
bin/setup
sudo rake install
sudo rake install:service

git clone https://github.com/pinecat/keal && cd keal && bin/setup && sudo rake install && sudo rake install:service # one-liner

Currently, bin/setup only supports RPM-based distros. I would like to add support for more distros in the near future, however, if you just want to try it out--on, say Ubuntu--you can run bundle install, and then you'll need to get the following from your package manager:

• glibmm2.4 headers
• ruby development headers
• make
• g++

$ keal [options] [program [args]]

Right now, keal has two options that affect how it runs: -i, and -l. The -i option will disable screen idle (meaning the screen will never turn off it's display). In current versions of GNOME, this is also disable the lock-screen, as the screen will only ever lock after the display as gone blank. The -l option--which disables the screen from locking--may be specified alongside the -i option if you wish, however, it is redundant in that case.

After checking out the repo, run bin/setup to install dependencies. Then, run rake spec 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 the created tag, and push the .gem file to rubygems.org.
