## Summary Slang is basically a Slim template language for Crystal language, so the very same Slim parser works fine. Slim template: https://github.com/slim-template/slim Slang template: https://github.com/jeromegn/slang ## Test plan Create a simple slang file with some tailwind-css and check if the CSS is being extracted: ```slim doctype html html head title This is a title body.min-h-screen header.stick.top-0.z-10 section.max-w-4xl.mx-auto.p-4.flex.items-center.justify-between h1.text-3xl.font-medium This is a slang file ``` To test it, get any slim template, rename the extension to .slang Fixes tailwindlabs#17851 --------- Co-authored-by: Jordan Pittman <jordan@cryptica.me>
