render-ansi

render-ansi converts highlighted byte spans and resolved styles into ANSI/VT escaped terminal text.

What It Provides

• End-to-end helpers:
  • highlight_to_ansi(...) -> String
  • highlight_lines_to_ansi_lines(...) -> Vec<String>
• Low-level render helpers:
  • resolve_styled_spans(...)
  • render_ansi(...)
  • render_ansi_lines(...)

Quick Example

use highlight_spans::Grammar;
use render_ansi::highlight_to_ansi;
use theme_engine::load_theme;

fn main() -> Result<(), Box<dyn std::error::Error>> {
    let theme = load_theme("tokyonight-dark")?;
    let out = highlight_to_ansi(b"set x = 42", Grammar::ObjectScript, &theme)?;
    println!("{out}");
    Ok(())
}

When To Use This Crate

• Use this crate when you want terminal-ready ANSI output.
• If you have your own paint engine (for example native C/TUI), use highlight-spans + theme-engine directly and skip ANSI rendering.
