A Python script to pick a random photo from the specified directory, set the wallpaper (for both light and dark) and the accent color.
## Why does this exist
We'd like to change our wallpaper every 15 minutes and automatically set a pre-defined accent color for each photo. There are many GNOME Shell extensions out there that can do something similar, but we simply want to achieve the same effect **without using any extensions**, especially when upgrading to a pre-release GNOME version that many extensions don't support yet.
So instead of a GNOME Shell extension, we created a Python script that does everything via `gsettings` and hook it up to a systemd timer instead.
## How to use
1. Create a directory with desired photos and note its full path
2. In that directory, rename your photos according to this table
*Suppose the filename is example.jpg*
|Accent Color |Suffix |Expected filename |
|--------------|-------|-------------------|
|Blue |blue |example-blue.jpg |
|Teal |teal |example-teal.jpg |
|Green |gree |example-gree.jpg |
|Yellow |yell |example-yell.jpg |
|Red |redd |example-redd.jpg |
|Pink |pink |example-pink.jpg |
|Purple |purp |example-purp.jpg |
|Slate |- |*any file without valid suffix above*|
*This means if there is no valid color suffix at the end of file name, we will set the accent color to Slate.*
3. In `change-wallpaper.py`, replace the `directory_path` with the path from step 1
4. Put `change-wallpaper.py` to `~/.local/bin` and make sure it is in your `$PATH`
5. In `change-wallpaper.service` replace `youruser` in `ExecStart` line with your actual username.
6.**Optionally**, modify `change-wallpaper.timer` as needed. The default is set to *every 15 minutes*.
7. Put `change-wallpaper.service` and `change-wallpaper.timer` in `~/.config/systemd/user/` and run these commands to get started
