## Beschrijving

Kodosvet Code Block is a zero-bloat Gutenberg block for displaying code with syntax
highlighting powered by Highlight.js.

**Key Features:**

 * **Native Gutenberg Block** — Full support for the visual editor with Server-Side
   Rendering.
 * **14 Color Themes** — Atom One, GitHub, Monokai, Dracula, Nord, VS Code, Stack
   Overflow, Night Owl, Gruvbox, Solarized, Panda, Tomorrow Night, Shades of Purple,
   Tokyo Night.
 * **Smart Language Detection** — Automatic language identification using multi-
   layered heuristics for PHP, Bash, JavaScript, SQL, JSON, XML, and more.
 * **Swift Guard** — Prevents Highlight.js from misidentifying code as Swift.
 * **Dark/Light Toggle** — Switch all code blocks on the page between dark and light
   themes with one click.
 * **Copy to Clipboard** — One-click code copying with visual feedback.
 * **Line Numbers** — Toggleable line number gutter.
 * **Legacy Migrator** — Built-in tool to scan and convert old `core/code` and `
   core/preformatted` blocks.
 * **Zero Bloat** — Assets are loaded only when a code block is present on the page.
 * **No jQuery** — Pure Vanilla JS on the frontend.

**Migrator Tool:**

Navigate to **Tools  Kodosvet Code Block** to scan your site for legacy code blocks
and migrate them to the modern Kodosvet format with a before/after preview.

### Third-Party Libraries

Syntax highlighting is powered by [Highlight.js](https://highlightjs.org/) 11.11.1,
bundled locally in `vendor/hljs/` (core build + 22 theme stylesheets). Highlight.
js is licensed under the BSD-3-Clause License; the unminified source is available
at [github.com/highlightjs/highlight.js](https://github.com/highlightjs/highlight.js).
No external requests are made at runtime.

## Installatie

 1. Upload the `kodosvet-code-block` folder to `/wp-content/plugins/`.
 2. Activate the plugin through the ‘Plugins’ menu in WordPress.
 3. In the Block Editor, search for “Kodosvet” to insert a code block.
 4. Configure default theme and color palette under **Tools  Kodosvet Code Block**.

## FAQ

### Does this plugin require any build tools?

No. Kodosvet Code Block ships as vanilla JavaScript and CSS — no Node.js, webpack,
or build step required.

### How does the language auto-detection work?

The plugin uses a multi-layer approach:
 1. Explicit language selection in block
settings (highest priority). 2. Markdown fence detection (“`language). 3. First-
line language markers. 4. Smart heuristics for PHP, Bash, JavaScript, SQL, and other
languages. 5. Highlight.js auto-detection (with Swift Guard to prevent false positives).

### Can I migrate my existing code blocks?

Yes! Go to **Tools  Kodosvet Code Block** and click **Scan Posts**. The migrator
will find all posts with `core/code` or `core/preformatted` blocks and let you preview
and migrate them individually or in bulk.

### Does migration create revisions?

Yes. The migrator uses `wp_update_post()`, so WordPress creates a revision for each
migrated post. You can roll back through the standard Revisions interface.

### What happens when I delete the plugin?

The plugin removes its settings (theme preference and color palette) from the database.
Your code block content remains in the posts as Gutenberg block comments.
