Wrap output with custom HTML

JavaScript

const html = await highlight(
  'const x = 1',
  htmlInline({
    language: javascript,
    theme: dracula,
    header: {openTag: '<figure><figcaption>index.js</figcaption>', closeTag: '</figure>'},
  })
)

Rust

use lumis::{highlight, HtmlInlineBuilder, formatters::html::HtmlElement, languages::Language, themes};

let html = highlight(
    "fn main() {}",
    HtmlInlineBuilder::new()
        .language(Language::Rust)
        .theme(Some(themes::get("dracula").unwrap()))
        .header(Some(HtmlElement {
            open_tag: "<figure><figcaption>main.rs</figcaption>".to_string(),
            close_tag: "</figure>".to_string(),
        }))
        .build()
        .unwrap(),
);

Elixir

Lumis.highlight!(
  "const x = 1",
  formatter: {:html_inline,
    language: "javascript",
    theme: "dracula",
    header: %{open_tag: "<figure><figcaption>index.js</figcaption>", close_tag: "</figure>"}
  }
)
