TrixGenius is a Rails engine and generator that extends the Trix Editor with enhanced functionality using Hotwire (Turbo + Stimulus). It adds AI-powered buttons to the Trix toolbar — including a Correct Spelling feature — to make rich-text editing smarter, more dynamic, and user-friendly.

• 🚀 Plug-and-play generator to scaffold Trix enhancements into your app.
• 🎛️ StimulusJS controller for rich interaction with Trix Editor.
• ✍️ Correct Spelling button — adds a toolbar button to trigger spelling corrections (via API or local logic).
• 🔌 Hooks ready for integration with services like DeepSeek AI.
• 🧪 Designed for customization and extension.

⚠️ This is an alpha release. APIs and behaviors are subject to change as we gather feedback.

1. Add the gem to your Gemfile: https://rubygems.org/gems/trix-genius

   gem 'trix-genius', '~> 0.1.1'

2. Install the gem:

   bundle install

3. Set up Action Text:

   bin/rails action_text:install

4. (Optional) Create a scaffold to test it out:

   bin/rails g scaffold Post title:string content:rich_text
   bin/rails db:migrate

5. Install TrixGenius into your app:

   bin/rails g trix_genius:install

Once installed, your Trix editor will have an AI-enhanced Correct Spelling button.
This is enabled by default and ready to use in any form where you use Action Text’s rich_text_area.

Make sure your .env or Rails credentials include the required key:

DEEPSEEK_API_KEY=your_api_key_here

To enable the "Correct Spelling" button:

1. Make sure trix-genius is installed and your controller is connected.
2. The generator adds a correct_spelling button to the Trix toolbar via Stimulus.
3. Inside your trix_genius_controller.js, the correctSpelling method can trigger an AI call or local spellchecker logic.

<%= form.rich_textarea :content, rows: 4, data: { controller: "trix" }, class: ["block shadow-sm rounded-md border px-3 py-2 mt-2 w-full", {"border-gray-400 focus:outline-blue-600": post.errors[:content].none?, "border-red-400 focus:outline-red-600": post.errors[:content].any?}] %>

Press Button to Correct the text Spelling:

Trix Genius now supports evaluating math expressions inside parentheses within the Trix WYSIWYG editor — with a single click!

When a user types a math expression like (5 + 3 * 2), they can press the "Calculate" button (provided by the gem) to automatically evaluate and replace the expression with its result.

Input (before pressing "Calculate"):

• Add ChatGPT
• Add qwen.ai
• Allow enabled or disabled each feature
• Upload specs for Calculate Expression
