caffeine-ng 3.5.0

Tray bar app to temporarily inhibit screensaver and sleep mode.

Caffeine is a little daemon that sits in your systray, and prevents the screensaver from showing up, or the system from going to sleep. It does so when an application is fullscreened (eg: youtube), or when you click on the systray icon (which you can do, when, eg: reading).

This is a fork of Caffeine 2.4, since later versions dropped support for the systray icon in favour of only automatic detection of fullscreen apps only, which resulted rather controversial.

The intention of this fork is to also evolve on its own, not only fixing issues, but also implemented missing features, when relevant.

Caffeine-ng was shortly know as Taurine, a play on its successor’s name, since taurine is a known stimulant, commonly found in energy drinks. However, this name did not last, since the artwork would not match adequately, and changing it was undesirable.

Installation

To install Caffeine-ng please follow steps from appropriate chapter below

Generic installation

To manually install caffeine-ng, run:

python setup.py build
sudo python setup.py install
sudo glib-compile-schemas /usr/share/glib-2.0/schemas

Debian and derivatives

apt install python-docopt python-ewmh python-setproctitle python-wheel python-xdg

And mark them auto if you wish:

apt-mark auto python-docopt python-ewmh python-setproctitle python-wheel python-xdg

Then you need to build sources with:

make clean
make build

Create a package for your distribution:

checkinstall --pkgname=caffeine-ng --pkgversion=3.4 --requires="python-docopt \(\>=0.6.2\),python-ewmh \(\>=0.1.4\),python-setproctitle \(\>=1.1.10\),python-wheel \(\>=0.29.0\),python-xdg \(\>=0.25\)" --conflicts="caffeine" --nodoc python ./setup.py install --install-layout=deb

Replace version string with correct version and append this command with --install=no should you wish to inspect created package before installing it Replace python with python3 in package names above if you wish to build caffeine-ng with python 3

Replace python with python3 or python27 in checkinstall invocation to use specific python version to build caffeine-ng with

checkinstall is available for various distributions, so you may follow these steps adapting them to your distribution

Hacking

• To run: ./bin/caffeine

• To compile translations: ./update_translations

If you want to test out a translation without changing the language for the whole session: “LANG=ru_RU.UTF-8 ./bin/caffeine” (Replace ru_RU.UTF-8 with whatever language you want to use. You will need to a language pack for the specific language) Be aware that some stock items will not be translated unless you log in with a given language.
