Recent updates
13.2.1
6 months agoRelease 13.2.1 mainly addresses how `code` blocks with `lang` values containing spaces are converted into `className` values in the generated HAST. It also refactors JSDoc typing to use `@import` syntax and enables TypeScript declaration map generation.
13.2.0
6/7/2024Version 13.2.0 adds TypeScript typings so hast `ElementData` can include a `meta` field (intended for `data.meta` when converting from mdast to hast). The remaining changes are mostly internal refactors plus tooling and dependency upgrades.
Features13.1.0
1/11/2024Release 13.1.0 adds support for passing a `file` (a `VFile`) through the `toHast` options so handlers can reference the originating virtual file. The change is reflected in the TypeScript/JSDoc types, README configuration docs, and a new test that validates message emission via the provided `VFile`.
