Overview

The class-validity oracle for Verifier, built from a compiled Tailwind CSS file. Tailwind’s JIT generates a rule for every valid class it finds in your content globs — so as long as your component .rb files are in those globs, the compiled output contains exactly the valid classes among those you declared. A declared class missing from the output is a typo, a hallucination, or a value your theme doesn’t define.

oracle = ViewComponentCssDsl::Verifier::CompiledCssOracle.new(
  "app/assets/builds/tailwind.css"
)
oracle.include?("bg-blue-500")  # => true
oracle.include?("bg-blurple")   # => false

Caveat: the oracle is only as fresh as the build. Rebuild Tailwind before verifying, or a just-added valid class will be flagged as unknown.

Class selector: a dot, then word chars / hyphens / CSS escapes. Tailwind escapes special chars with a backslash (‘.hover:bg-blue-500`) and leading digits as hex (`.32 xl:grid`).
