v7.0.0

7.0.0

Highlights

• Major rewrite: parser now builds on css-tree for correctness and performance.
• Package is pure ESM and uses exports; no CommonJS output.
• Walker helpers are exposed via registerWalkers() and can enable walk* methods like walkWords.

Breaking changes

• ESM‑only: require('postcss-values-parser') is no longer supported. Use import.
• Node.js 20.19+ required (per engines).
• Walker helpers aren’t attached by default. If you relied on root.walkWords(...) in v6, call registerWalkers(Container) once to add the walk* methods.
• Internal AST is compatible but not identical (migrated to css-tree under the hood). Class names like Word, Numeric, Func, etc., remain.

Migration

• Replace CommonJS with ESM imports.

• Register walker helpers before using any walk* APIs:

  import { parse, Container, registerWalkers } from 'postcss-values-parser';
  registerWalkers(Container);

  const root = parse('var(--foo)');
  root.walkWords((word) => {
  if (word.isVariable) console.log(word.value);
  });

• Review docs for updated node shapes and stringifier behavior.
