See the Base16 repository for more information.
This theme was built with Base16 Builder.
As scide currently doesn't support theme files, themes have to be appended to
sc_ide_conf.yaml config file. On Linux systems this file is normally located at ~/.config/SuperCollider/sc_ide_conf.yaml
Make sure scide is closed while installing the themes.
Open sc_ide_conf.yaml on your favorite text editor and copy the desired
themes: entry from themes/*.yaml.
The base16-* themes should show up in the Configuration window on scide:
