Caffeine-ng

⚠️ Migrated to codeberg.org

This project has migrated to codeberg.org

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).

History

Caffeing-ng (since 2014) started as a fork of Caffeine 2.4, since the original version dropped support for the systray icon in favour of only automatic detection of fullscreen apps only, which turned to be a rather controversial decision.

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.

System requirements

• Python 3.6 to 3.9 is required.
• caffeine-ng works with the following screensavers / screenlockers:
  • Anything that implements the org.freedesktop.ScreenSaver API (this includes KDE, amongst others)
  • gnome-screensaver
  • XSS
  • Xorg + DPMS
  • xautolock
  • xidlehook.

See setup.py for required python packages

Installation

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

First install all the required packages:

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

And mark them auto if you wish:

apt-mark auto python-click 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-click \(\>=0.6.2\),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 in checkinstall invocation to use specific python version to build caffeine-ng.

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.
