⚠️ Pre-Release
--------------

[](#️-pre-release)

This plugin is in active development and not yet available on the Craft Plugin Store. Features and APIs may change before the initial public release.

Features
--------

[](#features)

- **Code field with a real editor** — live syntax highlighting in the Control Panel, with line numbers, tab/indent handling, undo/redo, and an optional in-editor language switcher
- **~177 languages** — Prism's full language set, bundled and loaded on demand (with dependency resolution); choose which appear in field dropdowns
- **25 themes** — from classic Prism themes to Dracula, Nord, One Dark, VS Code Dark+ and more; set one plugin-wide or override it per page
- **Highlighting extras** — line numbers, copy-to-clipboard button, matching-brace highlighting, and inline CSS colour swatches
- **Twig API** — print a Code field, re-render with overrides, or highlight any string with the `|highlight` / `|prism` filters
- **Integration trait** — let other plugins highlight code with graceful fallback when this plugin isn't installed
- **Bundled & offline** — Prism core, all languages, and all themes are served from the plugin's own assets (no CDN)
- **CSS-variable theming** — restyle the wrapper and copy button without overriding selectors
- **12 languages** — Control-Panel UI translated out of the box
