Describe your issue

In Clojure, it seems that surrounding brackets interfere with the extraction of classes from keywords. E.g.:

(when condition :bg-white :bg-black)

The presence of ) at the end seems to prevent :bg-black from being captured. I have a suggestion for how to fix this in the pre-processor, but I'm afraid that my limited experience of Rust will show, so I will kindly ask for your good input on the matter.

The root cause is that Tailwind’s scanner expects class names as plain strings, not as Clojure keywords or in bracketed/newline-separated forms. The most reliable solution is to always use strings for class names in your Clojure code and, if needed, implement a custom extractor or safelist for edge cases. If you want to contribute a fix or improve the extractor, you can look into writing a custom regex or extractor in your Tailwind config.

Using keywords for classes is quite common in Clojure, and it's a tall order to ask all of those codebases to change, and people to change their habits. Other than that, Clojure syntax is complete, and will never change. V4 currently supports a subset of Clojure syntax, and there are just a couple of things to iron out, so IMO it makes sense to bring that up to 100% and then it's done, permanently.
