Release Notes

Added

  • wasm: source maps. The @momiji-rs/sasso package's compile(scss, { sourceMap: true [, sourceMapIncludeSources: true] }) now returns
    { css, sourceMap } (the v3 map as a parsed object) instead of a bare CSS
    string; without sourceMap it still returns the string (backwards
    compatible). New sasso_compile_map export returns a framed [u32 css_len][css] [map json] buffer. Source maps are now exposed on every surface (lib, CLI,
    wasm).

Fixed

  • Compressed source maps now emit one segment per source line, matching
    dart-sass (compressed packs many tokens onto a line; dart maps only the first
    per source line). Expanded maps are unchanged. The map's CSS is unaffected.
