Follow-up to #28744, same root cause in other places. With `sortTailwindcss` on and `preserveWhitespace` off, Tailwind class strings and templates are printed with their whitespace collapsed, but these layout decisions read the source text, so formatting took two runs: ```ts // Sole template argument of a Tailwind call const a = clsx(` p-4 flex items-center ${active ? "bg-white" : "bg-black"} text-black `); // Arrow body tagged with a Tailwind function const b = () => tw` p-4 flex items-center bg-white text-black `; // Short object key (tabWidth: 4) const c = clsx({ "a b": someLongCondition }); ``` - `is_multiline_template_starting_on_same_line` now returns `false` for a template whose line breaks are collapsed - It reads the current Tailwind context (what `TemplateElement` reads) or the one a Tailwind tag pushes, so the arrow body, sole argument and member chain routing callers follow the print - `write_tailwind_string_literal` returns its printed width, and `write_member_name` uses it for the short key decision - An upper bound: the sorter also drops duplicates of known classes - `tailwind_context_for_callee` is shared by the call and tagged template pushes and the layout check, like `tailwind_context_for_jsx_attribute` in #28744 Outputs match Prettier + prettier-plugin-tailwindcss and are idempotent. Not covered here: `is_short_argument` (#28745), Tailwind calls through `MemberChain` never pushing the context, and computed keys. AI assistance (Claude Code) was used for this change.

/oʊ ɛks siː/
The Oxidation Compiler is a collection of high-performance tools for JavaScript and TypeScript written in Rust.
Oxc is part of VoidZero's vision for a unified, high-performance toolchain for JavaScript. It powers Rolldown (Vite's bundler) and enables the next generation of ultra-fast development tools that work seamlessly together.

🙋 Who's using Oxc?
Rolldown and Nuxt use Oxc for parsing. Rolldown also uses Oxc for transformation and minification. Nova, swc-node, and knip use oxc_resolver for module resolution. Preact, Shopify, ByteDance, and Shopee use oxlint for linting.
