kshift - KDE Theme Shift

kshift is a KDE theme shifting script that activates at set times to switch themes, including sunrise and sunset. When run manually, it sets the color theme and/or wallpaper to the 'correct' value based on current time. It uses plasma-apply-colorscheme for color themes, plasma-changeicons for icon themes, plasma-apply-wallpaperimage for wallpapers, and python os.system() for commands.

During installation, kshift sets systemd timers to run the script at any time a theme is set, including sunrise/sunset. The times set can be the sunrise/sunset keywords or ANY valid 'OnCalendar' time. Information on 'OnCalendar' syntax and capability is available in more detail here

The sunrise and sunset times are updated when kshift is ran.

Installation

Required Programs

• KDE Plasma
• Systemd
• Python 3
• Colorama

Instructions

1. Clone and enter kshift

   $ git clone https://github.com/justjokiing/kshift
   $ cd kshift/src
   

2. Edit the default variables in the variable file defaults.yml or look at usage for command line arguments

    location: USNY0996 # Location Code from https://weather.codes/search
    sunrise: '07:00'   # Default sunrise time, when time data cannot be accessed. These must be in quotes.
    sunset: '19:00'    # Default sunset  time
    rise_delay: 0      # Hour delay for sunrise, can be negative
    set_delay: 0       # Hour delay for sunset
    webdata: true      # Boolean for accessing web for time data
    net_timeout: 10    # How long to wait for network timeout
    themes:
      day:
        colorscheme: BreezeLight  # Check 'plasma-apply-colorscheme -l' for options
        icontheme: breeze
        wallpaper: /usr/share/wallpapers/Flow/contents/images/5120x2880.jpg
        command: ''               # Runs command at theme activation
        time: sunrise             # Keywords 'sunrise', 'sunset', or ANY correct systemd 'OnCalendar' time
      night:
        colorscheme: BreezeDark
        icontheme: breeze-dark
        wallpaper: /usr/share/wallpapers/Flow/contents/images_dark/5120x2880.jpg
        command: ''
        time: 
          - sunset
      october:
        wallpaper: /usr/share/wallpapers/FallenLeaf/contents/images/2560x1600.jpg
        time: '*-10-* *:*:*'
        enabled: false            # Disables theme, it will not run on time
   

   The themes default are set to a set of default day and night KDE themes and wallpapers. You can add as many themes as you would like at many different times, wallpapers, commands, icons, and colorschemes. None of the theme variables are required. If time is not set, there will be no automatic transition. The default for 'enabled' is true.

   The time variables "sunrise" and "sunset" are keywords to kshift and are replaced with the sunrise and sunset times that your location variable sets. Each theme's time will be converted to SystemD 'OnCalendar' syntax. Make sure to use correct YAML syntax.

3. Create the systemd services and add kshift to local bin

   $ ./kshift --install
   

   kshift will now be be installed to ~/.local/bin . Ensure that directory is in $PATH if wanted to be manually executed. The kshift timer will be updated after each execution.

   kshift variables will then be located at ~/.config/kshift/kshift.yml and follows the same format of defaults.yml, any further variable can be done by editing that file or using the --install option.

4. Now check to see if the system timers are on and working.

   $ ./kshift --status
   

   Then test out your themes.
