f.lux indicator applet

Better lighting for your computer

The f.lux indicator applet fluxgui is an indicator applet to control xflux, an application that makes the color of your computer's display adapt to the time of day: warm at night, and like sunlight during the day. Reducing blue light exposure in the evening can help you fall asleep at night. See https://justgetflux.com/research.html for more details.

This project -- https://github.com/xflux-gui/fluxgui -- is only concerned with the fluxgui indicator applet program, not with the underlying xflux program the indicator applet controls. The xflux program is responsible for actually changing the color of your screen. See https://justgetflux.com/linux.html for more information about xflux.

xflux is downloaded automatically when installing fluxgui. Simply run fluxgui in your terminal after installation to open the applet. You can also easily configure the applet to auto-start on login.

Install Instructions

Only Python 3 is Supported

The fluxgui is only known to work with Python 3.

Ubuntu PPA Package Manager Install

To install via apt:

sudo add-apt-repository ppa:nathan-renniewaldock/flux
sudo apt-get update
sudo apt-get install fluxgui

See ubuntuhandbook.org instructions for more details.

If you have trouble with the PPA version try the manual install below.

Fedora Package Manager Install

There is no Fedora package provided yet. Please use Manual Install below.

Manual Install

To install manually you first install the dependencies using your package manager, and then install fluxgui using the provided setup.py. The manual install can be done locally or system wide.

Install Dependencies Using Package Manager

Ubuntu/Debian

Partial list of Python 3 dependencies (after the uprgrade to GTK+ 3 in PR #112. If you discover the correct deps, please submit a PR):

sudo apt-get install python3-distutils gir1.2-appindicator3-0.1 gir1.2-gtk-3.0

Out of date Python 2 dependencies; the remaining Python 3 deps should be similar:

sudo apt-get install git python-appindicator python-xdg python-pexpect python-gconf python-gtk2 python-glade2 libxxf86vm1  libcanberra-gtk-module
Fedora/CentOS

WARNING: these dependencies may be out of date after the uprgrade to GTK+ 3 in PR #112. If you discover the correct deps, please submit a PR.

sudo yum install git python-appindicator python2-pyxdg python3-pexpect gnome-python2-gconf pygtk2 pygtk2-libglade

Install fluxgui

There are separate instructions in the code below for installing system wide and for installing locally in your user directory; choose one.

# Download fluxgui
cd /tmp
git clone "https://github.com/xflux-gui/fluxgui.git"
cd fluxgui
./download-xflux.py

# EITHER install system wide
sudo ./setup.py install --record installed.txt

# EXCLUSIVE OR, install in your home directory
#
# The fluxgui program installs
# into ~/.local/bin, so be sure to add that to your PATH if installing
# locally. In particular, autostarting fluxgui in Gnome will not work
# if the locally installed fluxgui is not on your PATH.
./setup.py install --user --record installed.txt
       
# Run flux
fluxgui

Manual Uninstall

If you manually installed instead of using package manager, you can uninstall by making setup.py tell you where it installed files and then removing the installed files.

# EITHER uninstall globally
#
# The 'installed.txt' is generated when you install. Reinstall first if you
# as described above if you don't have an 'installed.txt' file.
sudo xargs rm -vr < installed.txt
sudo glib-compile-schemas "$(dirname "$(grep apps.fluxgui.gschema.xml installed.txt)")"

# EXCLUSIVE OR uninstall in your home directory
xargs rm -vr < installed.txt
glib-compile-schemas "$(dirname "$(grep apps.fluxgui.gschema.xml installed.txt)")"

Developing

Coding Style

Try to stick to the same coding style that is already used in the file you are editing. In particular, don't change the style of code you're not already editing for some other reason. Style changes create noise in the Git history and make the git blame output misleading. When reviewing a PR, the maintainers want to focus on the logical changes introduced by your code, and extraneous style changes make that harder.

Running fluxgui Without Installing

When working on fluxgui, you can use

cd <path to your fluxgui.git clone>
# You only need to download xflux once.
./download-xflux.py
glib-compile-schemas .
GSETTINGS_SCHEMA_DIR=`pwd` PATH=`pwd`:$PATH PYTHONPATH=`pwd`/src:$PYTHONPATH ./fluxgui

to test your local copy of fluxgui without installing anything.

Change Logs, Versions, Releases

Note changes in ./debian/changelog.

Use version <ver>~pre until ready to release a version. When releasing a version remove the ~pre suffix from the version strings and commit, copying the changelog changes for the current release into the commit message. Then git tag -a v<ver>, using the commit msg for the tag annotation. Finally, create another commit with the new <next version>~pre version strings and changelog entry.

When releasing the version string needs to be changed in debian/changelog and setup.py, and the release dates needs to be added in debian/changelog.

You can’t perform that action at this time.
