damascene-html

HTML → Damascene El transformer.

use damascene_core::prelude::*;
use damascene_html::html;

let tree: El = html("<h1>Hi</h1><p>Hello <strong>world</strong>.</p>");

damascene-html is a focused HTML-to-El transformer, not a browser engine. Damascene's widget kit already echoes most of HTML's semantic vocabulary (text_runs ≈ <p>, span modifiers ≈ inline tags, bullet_list ≈ <ul>, code_block ≈ <pre><code>, table ≈ <table>, …), so a parse through html5ever plus a tag-by-tag mapping onto the existing widget vocabulary produces a faithful render for the subset of HTML that actually fits.

Coverage, in tiers:

• Direct widget mapping — headings, paragraphs with the inline tag set, nested lists (including the task-list shape), block quotes, <pre><code class="language-X">, <hr>, the full table tag family, <img> placeholders.
• Inline style="…" — color, background, padding, border, radius, opacity, sizing, text-align, font properties, text-decoration.
• <style> blocks — tag / class / id / compound / comma-grouped selectors with full specificity sort.
• Generic containers — <div>, <section>, <details>, <figure>, <button>, <input type="checkbox"> (cosmetic).
• Layout reshape — display: flex with direction/alignment, overflow (clip / scroll wrap), box-shadow, monospace font-family detection, margins reconciled into parent gap.

Properties and selectors without a Damascene equivalent drop with lint Findings exposed through the _with_lints entry points — silent fidelity loss is treated as a bug in the contract.

Script-capable content (<script>, <iframe>, on* attributes, javascript: URLs, …) is always dropped. Embedders handling untrusted HTML should still layer a dedicated sanitizer (e.g. ammonia) in front.

Used standalone, or via damascene-markdown's html feature to render inline/block HTML inside markdown. Full contract in the crate rustdoc: docs.rs/damascene-html.
