Crate tuika_html 

Terminal-native HTML for tuika.

Two ways in, one engine behind both:

• HtmlRenderer plugs into markdown through tuika’s MarkdownBlockRenderer seam. One implementation handles raw <details>, <table>, and <div> blocks as well as ```html fences.
• Html is a View, the standalone viewer: hand it a fragment, place it in a layout, and it paints like Markdown does.

use tuika::prelude::*;
use tuika_html::{Html, HtmlRenderer};

// In markdown:
let renderer = HtmlRenderer::new();
let doc = Markdown::new("<details><summary>Notes</summary>Body</details>")
    .block_renderer(&renderer);

// Standalone:
let view = Html::new("<h1>Title</h1><p>Prose with <b>bold</b>.</p>");

What renders

Headings, paragraphs, lists (ordered, unordered, nested), definition lists, block quotes, <pre>, <hr>, <table>, <details>/<summary>, and the presentational inline elements — <b>, <em>, <code>, <kbd>, <mark>, <a>, <img> (as alt text), <br>, <sub>, <sup>. Unknown elements stay transparent, so their text still shows. <script>, <style>, and embedded objects are dropped with their content.

Styling resolves through the active StyleSheet roles rather than colors of its own, so HTML inherits the host’s theme along with everything else on the screen.

What does not

There is no CSS, no style attribute, no floats or positioning, and no layout that depends on the document outside the fragment. This renders content, not pages — the goal is that HTML in a transcript reads as well as the markdown around it, not that a terminal becomes a browser.

Untrusted input

HTML in a transcript is untrusted. Control bytes are stripped before any text becomes a cell, so markup can never emit terminal commands; input, output, and nesting are bounded by Limits, and exceeding either the input-size or the nesting bound returns None (markdown then drops the block) rather than doing unbounded work. Nesting is measured on the source before parsing, because html5ever builds — and drops — its tree recursively, and deep enough markup overflows the stack inside the size bound. No network is touched: <img> becomes its alt text, never a fetch.

Structs

Html

A view that renders an HTML fragment to its area.

HtmlRenderer

Renders HTML for tuika’s structured markdown block seam.

Limits

Bounds on one render.

Functions

to_lines

Render an HTML fragment to width-fitted styled lines.

to_lines_with_limits

to_lines with explicit Limits: None when the input is over max_input_bytes.
