Swap Alfred theme at sunrise and sunset. Goes well with f.lux and macOS's night mode.
It uses launchd to call itself at sunrise and sunset (or as soon thereafter as your machine boots/wakes), and tells Alfred to change its theme.
toggle_alfred_theme.py [-v|-q] [-d|--dark <theme>] [-l|--light <theme>]
**You must first edit this script (or the accompanying bash wrapper)
to set your location!**
These scripts (Python script and bash wrapper) live at:
https://gist.github.com/deanishe/ce442c3a768adedc9c39
Change Alfred's theme depending on whether it's dark outside. Theme
is changed immediately when the script is run and the script will
also call itself again at sunrise and sunset (via launchd) to change
Alfred's theme. It's works well together with F.lux, which can
switch to Yosemite's dark mode at sunset.
Just run the script *once* with your preferred themes:
python toggle_alfred_theme.py --dark 'Dark Theme' --light 'Light Theme'
or if you're using the wrapper:
toggle-alfred-theme.bash --dark 'Dark Theme' --light 'Light Theme'
and it will ensure Alfred's theme is changed every day at sunrise
and sunset.
To change your preferred themes, just run the script again.
Note: Because the script calls itself via launchd, if you move the
script, it will stop working until you run it again.
Usage:
toggle_alfred_theme.py (-h|--help)
toggle_alfred_theme.py --timezones
toggle_alfred_theme.py (-t|--times)
toggle_alfred_theme.py [-n] [-v|-q] [--dark <theme>] [--light <theme>]
Options:
-h, --help Show this help message
-n, --nothing Show what would be set, but make no changes
-t, --times Show sunrise and sunset times for next 7 days
--timezones Show a list of (>500) supported timezones
-l, --light <theme> Alfred theme to use after sunrise
-d, --dark <theme> Alfred theme to use after sunset
-v, --verbose Show debugging info
-q, --quiet Only show warnings and errors
Installation & Setup:
This script requires the `astral` and `pytz` libraries. Install with:
pip install astral
It's better to install them in the same directory as this script (or
use a virtualenv), in order not to muck up your Python installation
or break other software:
pip install --target=/directory/where/this/script/is astral
Adjust the settings at the top of this script in the CONFIG section
(or in the bash wrapper) to match your location.
`TZ_NAME` must be one of the timezones recognised by `pytz`. To see
a list of all supported timezones, run this script with the
--timezones option. (Note there are over 500 timezones.)
You can usually find your town's latitude, longitude and elevation
on its Wikipedia page.
How it works:
When run, the script will immediately set Alfred's theme according
to whether it's light or dark out, then tell OS X to run the script
again at the next sunset/sunrise. Even if your computer is off/asleep
when the script is supposed to run, it will be run immediately on
boot/wake.
Note: Yosemite has some issues with running LaunchAgents on wake. If
the script isn't running when it's supposed to on Yosemite, but the
script reports the correct times, it's a problem with Yosemite, not
this script.
The script has to fork into the background (i.e. exit successfully
immediately) because `launchctl` doesn't like the script updating
the Launch Agent while it's running it.
There are two files, the Python script and a bash wrapper. The wrapper's only purpose is to store your configuration, so you can upgrade the Python script without having to edit it again.
You must set your location in one of the scripts before usage.
You can usually find the latitude, longitude and elevation of your town on its Wikipedia page.
