Sugar Dark login theme for SDDM

Sugar is extremely customizable and so sweet it will probably cause you diabetes just from looking at it. Sweeten the login experience for your users, your family and yourself. Sugar is cross platform and all about user experience and functionality. With those principles in mind Sugar was written completely from scratch making it clean and simple not only by looks but by design too.
All controls use the latest Qt Quick Controls 2 for increased performance on low end or even embedded systems and beautiful color transitions.

To learn how to control sugar levels you should check the Sugar Wiki on Github or the very well documented and included theme.conf. Here are some previews of nifty variable names you can set/unset/change to customize your sugar: ThemeColor, Font, HourFormat, ForceRightToLeft, TranslateUsernamePlaceholder This is just a teaser. There are 27 customizable variables in total! This sugar will be yours and only yours.
Sugar comes in two flavors. This one is for the bitter sweet. You can also check out Sugar Light.

Dependencies

sddm >= 0.18.0, qt5 >= 5.11.0, qt5-quickcontrols2 >= 5.11.0, qt5-svg >= 5.11.0

Make sure these are up to date!

Installing the theme

From KDE Plasma

If you are on KDE Plasma—by default openSuse, Neon, Kubuntu, KaOS or Chakra for example—you are lucky and can simply go to your system settings and under "Startup and Shutdown" followed by "Login Screen (SDDM)" click "Get New Theme". From there search for "Sugar Dark" and install.

If for some reason you cannot find the category named "Login Screen (SDDM)" in your system settings then you are missing sddm-kcm. Install this little helper with your package manager first. You will be grateful you did.

From other desktop environments

Download the tar archive from openDesktop and extract the contents to the theme directory of SDDM (change the path for the downloaded file if necessary):

$ sudo tar -xzvf ~/Downloads/sugar-dark.tar.gz -C /usr/share/sddm/themes

This will extract all the files to a folder called "sugar-dark" inside of the themes directory of SDDM.

After that you will have to point SDDM to the new theme by editing its config file, preferrably at /etc/sddm.conf.d/sddm.conf (create if necessary). You can take the default config file of SDDM as a reference: /etc/sddm.conf/usr/lib/sddm/sddm.conf.d/sddm.conf.

In the [Theme] section simply add the themes name: Current=sugar-dark. Also see the Arch wiki on SDDM.

Theming the theme

Sugar is extremely customizable by editing its included theme.conf file. You can change the colors and images used, the time and date formats, the appearance of the whole interface and even how it works.
And as if that wouldn't still be enough you can translate every single button and label because SDDM is still lacking behind with localization and clearly needs your help!

Please read the Sugar Wiki on Github for a detailed description of every variable available, what it does and the values it accepts. The theme.conf itself is also very well commented for you to get right at it.

Motivate a developer

In the past years I have spent quite some hours on open source projects. If you are the type of person who digs attention to detail, know how much work is involved in it and/or simply likes to support makers with a coffee or a beer I would greatly appreciate your donation on my PayPayl account.
Alternatively downloading my themes directly from opendesktop or with the kde sddm system settings module will at least help me a little to be able to attend your issues and requests.
Please consider helping developers you think are worth a penny or two, literally.
