arborium-highlight

Core syntax highlighting engine for arborium.

Features

This crate provides the unified highlighting engine that works with both:

• Statically linked Rust grammars: For CLI tools and servers
• Dynamically loaded WASM plugins: For browser contexts

Why Async?

The parsing is synchronous (tree-sitter fundamentally is), but getting a grammar can be async in browser contexts where plugins are loaded from a CDN via dynamic import(). The async trait supports both use cases with the same API.

Usage

use arborium_highlight::{Span, spans_to_html, HtmlFormat};

// After getting spans from a grammar...
let html = spans_to_html(source, spans, &HtmlFormat::CustomElements);
