A markdown rendering widget with syntax highlighting for code blocks.

Uses the tui-markdown Rust crate (powered by pulldown-cmark + syntect) to parse markdown and render it with styled text spans. Supports headings, bold, italic, inline code, fenced code blocks with syntax highlighting, bullet lists, links, and horizontal rules.

Ideal for rendering AI assistant responses in a chat interface.

Fenced-code highlighting uses syntect's bundled base16-ocean.dark theme, which is hardcoded by tui-markdown and cannot be overridden through its public API. For themed code display, use ExRatatui.Widgets.CodeBlock directly.

Fields

• :content - the markdown text to render
• :style - %ExRatatui.Style{} for the widget background
• :block - optional %ExRatatui.Widgets.Block{} container
• :scroll - {vertical, horizontal} scroll offset (default: {0, 0})
• :wrap - true to wrap text at widget boundary (default: true)

Examples

iex> %ExRatatui.Widgets.Markdown{content: "# Hello\n\nSome **bold** text."}
%ExRatatui.Widgets.Markdown{
  content: "# Hello\n\nSome **bold** text.",
  style: %ExRatatui.Style{},
  block: nil,
  scroll: {0, 0},
  wrap: true
}

iex> alias ExRatatui.Widgets.{Markdown, Block}
iex> %Markdown{
...>   content: "Some text",
...>   block: %Block{title: "Response", borders: [:all]}
...> }
%ExRatatui.Widgets.Markdown{
  content: "Some text",
  style: %ExRatatui.Style{},
  block: %ExRatatui.Widgets.Block{title: "Response", borders: [:all]},
  scroll: {0, 0},
  wrap: true
}
