pygmentize

Rust library and wrapper around the pygmentize CLI. Apply syntax highlighting to over 500 languages and other text formatted. Render into HTML, SVG, LaTeX, and Terminal (ANSI color sequences).

Example

use pygmentize::{HtmlFormatter, PygmentizeError};

let code = r#"fn main() {
    println!("Hello, world!");
}"#;

let html = pygmentize::highlight(code, Some("rust"), &HtmlFormatter::default())?;
println!("{html}");

Output

(whitespace added to improve clarity)

<div class="highlight">
<pre>
    <span></span>

    <span class="k">fn</span>
    <span class="nf">main</span>
    <span class="p">()</span>
    <span class="w"> </span>
    <span class="p">{</span>

    <span class="w">    </span>
    <span class="fm">println!</span>
    <span class="p">(</span>
    <span class="s">&quot;Hello, world!&quot;</span>
    <span class="p">);</span>

    <span class="p">}</span>
</pre>
</div>
