tui-syntax

Tree-sitter based syntax highlighting for TUI applications.

This crate provides syntax highlighting that integrates with ratatui, returning styled Line and Span types ready for rendering.

Features

• Tree-sitter based highlighting (accurate, fast)
• Helix-compatible TOML theme format
• Built-in themes (One Dark, GitHub Light)
• SQL language support built-in
• Extensible to other languages via tree-sitter grammars

Example

use tui_syntax::{Highlighter, themes, sql};

// Create highlighter with default dark theme
let mut highlighter = Highlighter::new(themes::one_dark());

// Register SQL language
highlighter.register_language(sql()).unwrap();

// Highlight some SQL
let lines = highlighter.highlight("sql", "SELECT * FROM users WHERE id = 1;").unwrap();

// `lines` is Vec<ratatui::text::Line> ready to render
