Base16 for Rofi

Copy or link the desired base16-*.rasi theme files to ~/.local/share/rofi/themes/.

git clone https://github.com/tinted-theming/base16-rofi.git
ln -s base16-rofi ~/.local/share/rofi/themes/
rofi -theme base16-default-dark

For older Rofi versions (< 1.4), copy the desired base16-*.config theme file to ~/.config/rofi/config.

git clone https://github.com/jordiorlando/base16-rofi.git
mkdir ~/.config/rofi
ln -s base16-rofi/themes/base16-default-dark.config >> ~/.config/rofi/config

On Fedora, run:

dnf install rofi-themes-base16

For Rofi < v1.4 this repo also provides a hook to switch the color scheme automatically when a base16_shell theme is set. Note that for now, this only works when there is no existing Rofi config file (to avoid overwriting it). The setup is pretty straightforward:

export BASE16_SHELL_HOOKS=$HOME/.config/base16-shell/hooks
mkdir -p $BASE16_SHELL_HOOKS
cp hook/rofi.sh $BASE16_SHELL_HOOKS && chmod +x $BASE16_SHELL_HOOK/rofi.sh

Then set the rofi_config_file and rofi_themes_dir variables in the script.
