A script to change lightdm-slick-greeter's theme with pywal.

Currently, the slickgreeter-pywal install script will generate a wallpapers directory in /usr/share with full read and write permissions, and it will generate/edit /etc/lightdm/slick-greeter.conf so that there is a [Greeter] section and the line background=/usr/share/wallpapers/wal within the greeter section. The reTheme script just calls wal -i <path-to-image> and copies the image to the file /usr/share/wallpapers/wal.

Once the install script has been run, simply use the command reTheme <path-to-image> inplace of wal -i <path-to-image>.

sudo chmod +x install.sh
sudo ./install.sh
reTheme $(cat $HOME/.cache/wal/wal)

Note that on line 3: (cat $HOME/.cache/wal/wal) can be replaced with the full path to any image.

When the install script is run, the commands reTheme and slick-pywal can be run from the terminal.

The reTheme script works just like the wal -i <path-to-image> command would, except it updates the file that slick-greeter gets it's wallpaper from in addition to calling wal on the image.

reTheme <path-to-image>

The slick-pywal script just copies the last image that wal was invoked on to the file that slick-greeter gets it's wallpaper from.
