Crate zalo 

A syntax highlighting library using TextMate grammars and themes and producing the same output as VSCode.

Example

use zalo::{HighlightOptions, HtmlRenderer, Options, Registry, ThemeVariant};

// Using the `dump` feature and loading the prebuilt assets
let registry = Registry::load_from_file("builtin.msgpack")?;
let code = "let x = 42;";

let options = HighlightOptions::new("javascript", ThemeVariant::Single("catppuccin-frappe"));
let highlighted = registry.highlight(code, options)?;

let render_options = Options {
    show_line_numbers: true,
    ..Default::default()
};
let html = HtmlRenderer::default().render(&highlighted, &render_options);
