amvcp-code-syntax

What problem does it solve?

Creates reliable, dependency-free syntax-highlighted code blocks with gutters, copy, and accurate multi-click line selection—while preserving byte-exact source fidelity for copy/paste.

Core Features & Use Cases

• Dependency-free tokenizer + integrity probe: highlights only when rendered text round-trips byte-exact to the original source; otherwise falls back to plain escaped text.
• Interactive code chrome: builds a per-line gutter, copy-to-clipboard button, wrap-marker stripe, and selection model from semantic HTML only.
• Theme-safe token palette: uses a 12-role token palette with mandatory light/dark mirrors and selection-yield rules so tokens remain readable when selected.
• Language resolution contract: supports a fixed alias map and deliberate fail-soft behavior (no guessing; unknown language => plain).

Quick Start

Render a code block by writing plain semantic HTML, declaring the language once (class="language-<id>" or data-ve-lang="<id>"), and letting the runtime tokenizer generate the gutter, copy button, tokens, and selection behavior.
