This CLI tool allows you to transform an Atom theme to CSS ready to be used by code highlighted with atom/highlights.
Atom themes are less files so a compilation is required when you want to use those directly.
This simple command clone, compile and adjust CSS for you.
Bu in case you want to...
npm install -g atom-syntax-theme-to-highlights-css
To output the CSS
npx atom-syntax-theme-to-highlights-css /~https://github.com/simurai/duotone-dark-sea-syntax
To copy directly into your clipboard
npx atom-syntax-theme-to-highlights-css --clipboard /~https://github.com/simurai/duotone-dark-sea-syntax
Note: an alias is also available if you have installed the package globally: atomst2hlcss
