- This style is based on Monaco font (https://github.com/todylu/monaco.ttf).
- Notepad++, of course.
Copy the Material-Dark.xml file to "%APPDATA%\Notepad++\themes" and in a portable installation to "%Notepad++%\themes".
Or simply import it to Notepad++ by going to Menu -> Settings -> Import -> Import Style theme(s) option.
