DWI (Dynamic Wallpaper Improved)

Overview

• 25+ different adaptive wallpapers included
• Easy manual addition of custom wallpapers
• Extensive Pywal support to adjust your program themes as well
• Uses cronjobs to reliably refresh the wallpaper (e.g. every hour)
• Tested on many setups (see the original repository for a list)
• Extended support for GNOME theming
• Many improvements (see below!)

System Requirements

Make sure your system fulfills the following requirements before using DWI:

• GNU Operating System (required): DWI makes use of a lot of standard GNU utilities (such as bash, grep, xargs, etc.). If you're using a common "Linux" distribution, you're probably running the GNU Operating System. If you're on a BSD, Windows, macOS or a demanding Linux distribution (such as Alpine Linux), this script will not work without significant workarounds! One way to make sure you're on GNU is by checking the output of uname -o in a terminal.
• feh (required): This is used to set the wallpaper in most environments
• cron (semi-required): While not necessary for DWI to function, you probably want to run this script every hour or so to refresh your background wallpaper. This can preferrably be done by using a cronjob. A popular tool to manage cronjobs is Cronie. An instruction on how to set up a cronjob with Cronie can be found in the original Dynamic Wallpaper program by adi1090x.
• xrandr (semi-required): Xrandr is only needed if you use the XFCE desktop environment
• pywal (optional): If you use Pywal to theme your applications like your desktop wallpaper, DWI can do that for you automatically!

Improvements

• General
  • Extended help message
  • Added script reinstall.sh to reinstall the dwall.sh script only, e.g. after an update (update via git pull --all --rebase or equivalent)
    Note: If you want to also receive new wallpapers from an update, you have to run install.sh and log in again (depending on your environment). You might be stuck with a black wallpaper until you reload your environment. If you want to avoid logging out, you can also first run uninstall.sh before installing everything again.
  • Removed seemingly unnecessary test.sh file
• Options
  • Added option to copy the wallpaper to a file instead of setting it directly (Thanks Kagia001! 💯)
• Environments
  • Added sway WM support (suggested by ramazanemreosmanoglu 👍)
• Wallpapers
  • Added macOS Big Sur adaptive wallpaper (Thanks egemertdogan! 🎉)
• Pywal
  • Added the option to pass in a different pywal backend using -b [BACKEND]
  • Added the option to create a light or dark theme based on
    • Forcing the light theme (using -l)
    • Automatically guessing day/night time by evaluating
      • The GNOME theme
      • The current time of day
• GNOME
  • DWI also refreshes the lock screen image
  • Better Pywal integration (by taking the current GNOME theme into account)
