syntax_highlighter_plus 0.2.0

A robust syntax highlighting Flutter package powered by TextMate grammars.

Changelog

0.2.0

• Bundled grammars are now zstd-compressed (assets/grammars/*.json.zst), decompressed on first use and cached for the process lifetime. Cuts the native library size roughly 4x with no measured tokenization overhead.
• Tuned the Rust release profile (LTO, single codegen unit, opt-level = "s", stripped symbols) for a smaller binary at no measured perf cost.

0.1.0

• Replaced the C FFI Oniguruma binding with a Rust TextMate tokenization engine (the onig crate via flutter_rust_bridge). Tokenization now runs asynchronously off the UI thread.
• TextMate grammars are embedded into the native library at build time; embedded languages (e.g. code blocks inside markdown, JS inside HTML) are resolved across grammars.
• Added VS Code theme parsing with TextMate scope-selector matching (SyntaxTheme), including font styles (italic/bold/underline/strikethrough).
• highlight() returns a compact TextSpan tree; adjacent runs with equal styles are merged. An optional style parameter supplies the base TextStyle.
• Token offsets are UTF-16 code units, correct for emoji/CJK sources.

0.0.2

• Integrated Oniguruma as the underlying regular expression engine for improved parsing and compatibility with TextMate grammars.

0.0.1

• Initial release.
